ROCKET PHARMACEUTICALS : Management’s Discussion and Analysis of Financial Condition and Results of Operations (form 10-Q) – marketscreener.com

You should read the following discussion and analysis of our financial conditionand results of operations together with the condensed consolidated financialstatements and related notes that are included elsewhere in this QuarterlyReport on Form 10-Q and our Annual Report on Form 10-K for the fiscal year endedDecember 31, 2019 filed with the U.S. Securities and Exchange Commission, or theSEC, on March 6, 2020, or our 2019 Form 10-K. This discussion containsforward-looking statements based upon current plans, expectations and beliefsthat involve risks and uncertainties. Our actual results may differ materiallyfrom those anticipated in these forward-looking statements as a result ofvarious factors, including, but not limited to, those discussed in the sectionentitled "Risk Factors" and elsewhere in this Quarterly Report on Form 10-Q. Inpreparing this MD&A, we presume that readers have access to and have read theMD&A in our 2019 Form 10-K, pursuant to Instruction 2 to paragraph (b) of Item303 of Regulation S-K. Unless stated otherwise, references in this QuarterlyReport on Form 10-Q to "us," "we," "our," or our "Company" and similar termsrefer to Rocket Pharmaceuticals, Inc.

We are a clinical-stage, multi-platform biotechnology company focused on thedevelopment of first, only and best-in-class gene therapies, with directon-target mechanism of action and clear clinical endpoints, for rare anddevastating diseases. We currently have three clinical-stage ex vivo lentiviralvector ("LVV") programs currently enrolling patients in the US and EU forFanconi Anemia ("FA"), a genetic defect in the bone marrow that reducesproduction of blood cells or promotes the production of faulty blood cells,Leukocyte Adhesion Deficiency-I ("LAD-I"), a genetic disorder that causes theimmune system to malfunction and Pyruvate Kinase Deficiency ("PKD"), a rare redblood cell autosomal recessive disorder that results in chronic non-spherocytichemolytic anemia. Of these, both the Phase 2 FA program and the Phase 1/2 LAD-Iprogram are in registration-enabling studies in the US and EU. In addition, inthe US we have a clinical stage in vivo adeno-associated virus ("AAV") programfor Danon disease, a multi-organ lysosomal-associated disorder leading to earlydeath due to heart failure. Finally, we have a pre-clinical stage LVV programfor Infantile Malignant Osteopetrosis ("IMO"), a genetic disorder characterizedby increased bone density and bone mass secondary to impaired bone resorption -this program is anticipated to enter the clinic in 2020. We have globalcommercialization and development rights to all of these product candidatesunder royalty-bearing license agreements. Additional work in the discovery stagefor an FA CRISPR/CAS9 program as well as a gene therapy program for the lesscommon FA subtypes C and G is ongoing.

Recent Developments

On February 20, 2020, we entered into separate, privately negotiated exchangeagreements (the "Exchange Agreements") with certain holders of our outstanding5.75% Convertible Senior Notes due 2021 (the "2021 Convertible Notes") to extendthe maturity date by one year. Pursuant to the Exchange Agreements, we exchangedapproximately $39.35 million aggregate principal amount of the 2021 ConvertibleNotes (which represents approximately 76% of the aggregate outstanding principalamount of the 2021 Convertible Notes) for (a) approximately $39.35 millionaggregate principal amount of 6.25% Convertible Senior Notes due August 2022(the "2022 Convertible Notes") (an exchange ratio equal to 1.00 2022 ConvertibleNote per exchanged 2021 Convertible Note) and (b) $119,416 in cash to pay theaccrued and unpaid interest on the exchanged 2021 Convertible Notes from, andincluding, February 1, 2020 to February 20, 2020. The 2022 Convertible Noteswere issued in private placements exempt from registration in reliance onSection 4(a) (2) of the Securities Act of 1933, as amended (the "SecuritiesAct"). Upon completion of the exchange transactions, approximately $12.65million aggregate principal amount of 2021 Convertible Notes remainedoutstanding.

Gene Therapy Overview

Genes are composed of sequences of deoxyribonucleic acid ("DNA"), which code forproteins that perform a broad range of physiologic functions in all livingorganisms. Although genes are passed on from generation to generation, geneticchanges, also known as mutations, can occur in this process. These changes canresult in the lack of production of proteins or the production of alteredproteins with reduced or abnormal function, which can in turn result in disease.

Gene therapy is a therapeutic approach in which an isolated gene sequence orsegment of DNA is administered to a patient, most commonly for the purpose oftreating a genetic disease that is caused by genetic mutations. Currentlyavailable therapies for many genetic diseases focus on administration of largeproteins or enzymes and typically address only the symptoms of the disease. Genetherapy aims to address the disease-causing effects of absent or dysfunctionalgenes by delivering functional copies of the gene sequence directly into thepatient's cells, offering the potential for curing the genetic disease, ratherthan simply addressing symptoms.

We are using modified non-pathogenic viruses for the development of our genetherapy treatments. Viruses are particularly well suited as delivery vehiclesbecause they are adept at penetrating cells and delivering genetic materialinside a cell. In creating our viral delivery vehicles, the viral (pathogenic)genes are removed and are replaced with a functional form of the missing ormutant gene that is the cause of the patient's genetic disease. The functionalform of a missing or mutant gene is called a therapeutic gene, or the"transgene." The process of inserting the transgene is called "transduction."Once a virus is modified by replacement of the viral genes with a transgene, themodified virus is called a "viral vector." The viral vector delivers thetransgene into the targeted tissue or organ (such as the cells inside apatient's bone marrow). We have two types of viral vectors in development, LVVand AAV. We believe that our LVV and AAV-based programs have the potential tooffer a long-lasting and significant therapeutic benefit to patients.

Gene therapies can be delivered either (1) ex vivo (outside the body), in whichcase the patient's cells are extracted and the vector is delivered to thesecells in a controlled, safe laboratory setting, with the modified cells thenbeing reinserted into the patient, or (2) in vivo (inside the body), in whichcase the vector is injected directly into the patient, either intravenously("IV") or directly into a specific tissue at a targeted site, with the aim ofthe vector delivering the transgene to the targeted cells.

We believe that scientific advances, clinical progress, and the greaterregulatory acceptance of gene therapy have created a promising environment toadvance gene therapy products as these products are being designed to restorecell function and improve clinical outcomes, which in many cases includeprevention of death at an early age.

The chart below shows the current phases of development of Rocket's programs andproduct candidates:

LVV Programs. Rocket's LVV-based programs utilize third-generation,self-inactivating lentiviral vectors to target selected rare diseases.Currently, Rocket is developing LVV programs to treat FA, LAD-I, PKD, and IMO.

Fanconi Anemia Complementation Group A (FANCA):

FA, a rare and life-threatening DNA-repair disorder, generally arises from amutation in a single FA gene. An estimated 60 to 70% of cases arise frommutations in the Fanconi-A ("FANCA") gene, which is the focus of our program. FAresults in bone marrow failure, developmental abnormalities, myeloid leukemiaand other malignancies, often during the early years and decades of life. Bonemarrow aplasia, which is bone marrow that no longer produces any or very few redand white blood cells and platelets leading to infections and bleeding, is themost frequent cause of early morbidity and mortality in FA, with a median onsetbefore 10 years of age. Leukemia is the next most common cause of mortality,ultimately occurring in about 20% of patients later in life. Solid organmalignancies, such as head and neck cancers, can also occur, although at lowerrates during the first two to three decades of life.

Although improvements in allogeneic (donor-mediated) hematopoietic stem celltransplant ("HSCT"), currently the most frequently utilized therapy for FA, haveresulted in more frequent hematologic correction of the disorder, HSCT isassociated with both acute and long-term risks, including transplant-relatedmortality, graft versus host disease ("GVHD"), a sometimes fatal side effect ofallogeneic transplant characterized by painful ulcers in the GI tract, livertoxicity and skin rashes, as well as increased risk of subsequent cancers. Ourgene therapy program in FA is designed to enable a minimally toxic hematologiccorrection using a patient's own stem cells during the early years of life. Webelieve that the development of a broadly applicable autologous gene therapy canbe transformative for these patients.

Each of our LVV-based programs utilize third-generation, self-inactivatinglentiviral vectors to correct defects in patients' HSCs, which are the cellsfound in bone marrow that are capable of generating blood cells over a patient'slifetime. Defects in the genetic coding of HSCs can result in severe, andpotentially life-threatening anemia, which is when a patient's blood lacksenough properly functioning red blood cells to carry oxygen throughout the body.Stem cell defects can also result in severe and potentially life-threateningdecreases in white blood cells resulting in susceptibility to infections, and inplatelets responsible for blood clotting, which may result in severe andpotentially life-threatening bleeding episodes. Patients with FA have a geneticdefect that prevents the normal repair of genes and chromosomes within bloodcells in the bone marrow, which frequently results in the development of acutemyeloid leukemia ("AML"), a type of blood cancer, as well as bone marrow failureand congenital defects. The average lifespan of an FA patient is estimated to be30 to 40 years. The prevalence of FA in the US and EU is estimated to be about4,000, and given the efficacy seen in non-conditioned patients, the addressableannual market opportunity is now thought to be in the 400 to 500 range.

We currently have one LVV-based program targeting FA, RP-L102. RP-L102 is ourlead lentiviral vector based program that we in-licensed from Centro deInvestigaciones Energticas, Medioambientales y Tecnolgicas ("CIEMAT"), whichis a leading research institute in Madrid, Spain. RP-L102 is currently beingstudied in our sponsored Phase 2 registrational enabling clinical trialstreating FA patients initially at the Center for Definitive and CurativeMedicine at Stanford University School of Medicine ("Stanford") and HospitalInfantil de Nino Jesus ("HNJ") in Spain. The Phase 2 portion of the trial isexpected to enroll ten patients total from the U.S. and EU. Patients willreceive a single IV infusion of RP-L102 that utilizes fresh cells and "ProcessB" which incorporates a modified stem cell enrichment process, transductionenhancers, as well as commercial-grade vector and final drug product.

--------------------------------------------------------------------------------

Table of ContentsIn October 2019, at the European Society of Cell and Gene Therapy ("ESGCT") 2019Annual Congress, long-term Phase 1/2 clinical data of RP-L102, from the clinicaltrial sponsored by CIEMAT, for FA "Process A", without the use of myeloablativeconditioning was presented demonstrating evidence of increasing and durableengraftment leading to bone marrow restoration exceeding the 10% thresholdagreed to by the FDA and EMA for the ongoing registration-enabling Phase 2trial. In patient 02002, who received what we consider adequate drug product,hemoglobin levels are now similar to those in the first year after birth,suggesting hematologic correction over the long term.

During the third quarter of 2019, we received alignment from the FDA on thetrial design and the primary endpoint. This alignment was similar to thatpreviously received from the European Medicines Agency ("EMA"). Resistance tomitomycin-C, a DNA damaging agent, in bone marrow stem cells at a minimum timepoint of one year to serve as the primary endpoint for our Phase II study. InDecember 2019, we announced that the first patient of the global Phase 2 studyfor RP-L102 "Process B" for FA received investigational therapy. There will betotal of 10 patients enrolled in the global Phase 2 studies.

In December 2019, we also announced preliminary results from two pediatricpatients treated with "Process B" RP-L102 prior to development of severe bonemarrow failure in our Phase 1 trial of RP-L102 for FA. To evaluate transductionefficiency, an analysis of the proportion of the MMC-resistant colony formingcells was conducted and both patients have thus far exhibited early signs ofengraftment, including increases in blood cell lineages in one patient. Nodrug-related safety or tolerability issues have been reported.

Leukocyte Adhesion Deficiency-I (LAD-I):

LAD-I is a rare autosomal recessive disorder of white blood cell adhesion andmigration, resulting from mutations in the ITGB2 gene encoding for the Beta-2Integrin component, CD18. Deficiencies in CD18 result in an impaired ability forneutrophils (a subset of infection-fighting white blood cells) to leave bloodvessels and enter into tissues where these cells are needed to combatinfections. As is the case with many rare diseases, true estimates of incidenceare difficult; however, several hundred cases have been reported to date.

Most LAD-I patients are believed to have the severe form of the disease. SevereLAD-I is notable for recurrent, life-threatening infections and substantialinfant mortality in patients who do not receive an allogeneic HSCT. Mortalityfor severe LAD-I has been reported as 60 to 75% by age two in the absence ofallogeneic HCST.

We currently have one program targeting LAD-I, RP-L201. RP-L201 is a clinicalprogram that we in-licensed from CIEMAT. We have partnered with UCLA to leadU.S. clinical development efforts for the LAD-I program. UCLA and its Eli andEdythe Broad Center of Regenerative Medicine and Stem Cell Research is servingas the lead U.S. clinical research center for the registrational clinical trialfor LAD-I, and HNJ is serving as the lead clinical site in Spain.

The ongoing open-label, single-arm, Phase 1/2 registration enabling clinicaltrial of RP-L201 has dosed one severe LAD-I patient in the U.S. to assess thesafety and tolerability of RP-L201. The first patient was treated with RP-L201in third quarter 2019. This study has received $6.5 million CLIN2 grant awardfrom the California Institute for Regenerative Medicine ("CIRM") to support theclinical development of gene therapy for LAD-I.

In December 2019, we announced initial results from the first pediatric patienttreated with RP-L201, demonstrating early evidence of safety. Analyses ofperipheral vector copy number ("VCN"), and CD18-expressing neutrophils wereperformed through three months after infusion of RP-L201 to evaluate engraftmentand phenotypic correction. The patient exhibited early signs of engraftment withVCN myeloid levels at 1.5 at three months and CD-18 expression of 45%. No safetyor tolerability issues related to RP-L201 administration (or investigationalproduct) had been identified as of that date. The study is expected to enrollnine patients globally.

Pyruvate Kinase Deficiency (PKD):

Red blood cell PKD is a rare autosomal recessive disorder resulting frommutations in the pyruvate kinase L/R ("PKLR") gene encoding for a component ofthe red blood cell ("RBC") glycolytic pathway. PKD is characterized by chronicnon-spherocytic hemolytic anemia, a disorder in which RBCs do not assume anormal spherical shape and are broken down, leading to decreased ability tocarry oxygen to cells, with anemia severity that can range from mild(asymptomatic) to severe forms that may result in childhood mortality or arequirement for frequent, lifelong RBC transfusions. The pediatric population isthe most commonly and severely affected subgroup of patients with PKD, and PKDoften results in splenomegaly (abnormal enlargement of the spleen), jaundice andchronic iron overload which is likely the result of both chronic hemolysis andthe RBC transfusions used to treat the disease. The variability in anemiaseverity is believed to arise in part from the large number of diverse mutationsthat may affect the PKLR gene. Estimates of disease incidence have rangedbetween 3.2 and 51 cases per million in the white U.S. and EU population.Industry estimates suggest at least 2,500 cases in the U.S. and EU have alreadybeen diagnosed despite the lack of FDA-approved molecularly targeted therapies.Enrollment is currently ongoing and we anticipate treating the first patient inthe third quarter of 2020.

--------------------------------------------------------------------------------

Table of ContentsWe currently have one LVV-based program targeting PKD, RP-L301. RP-L301 is aclinical stage program that we in-licensed from CIEMAT. The IND for RP-L301 toinitiate a global Phase 1 study was cleared by the FDA in October 2019. Thisprogram has been granted EMA orphan drug disease designation and FDA orphan drugdisease designation ("ODD").

This global Phase 1 open-label, single-arm, clinical trial is expected to enrollsix adult and pediatric transfusion-dependent PKD patients in the U.S. andEurope. Lucile Packard Children's Hospital Stanford will serve as the lead sitein the U.S. for adult and pediatric patients, and Hospital InfantilUniversitario Nio Jess will serve as the lead site in Europe for pediatricsand Hospital Universitario Fundacin Jimnez Daz will serve as the lead site inEurope for adult patients.

Infantile Malignant Osteopetrosis (IMO):

IMO is a genetic disorder characterized by increased bone density and bone masssecondary to impaired bone resorption. Normally, small areas of bone areconstantly being broken down by special cells called osteoclasts, then madeagain by cells called osteoblasts. In IMO, the cells that break down bone(osteoclasts) do not work properly, which leads to the bones becoming thickerand not as healthy. Untreated IMO patients may suffer from a compression of thebone-marrow space, which results in bone marrow failure, anemia and increasedinfection risk due to the lack of production of white blood cells. Untreated IMOpatients may also suffer from a compression of cranial nerves, which transmitsignals between vital organs and the brain, resulting in blindness, hearing lossand other neurologic deficits.

We currently have one LVV-based program targeting IMO, RP-L401. RP-L401 is apreclinical program that we in-licensed from Lund University, Sweden. Thisprogram has been granted ODD and Rare Pediatric Disease designation from theFDA. The FDA defines a "rare pediatric disease" as a serious andlife-threatening disease that affects less than 200,000 people in the U.S. thatare aged between birth to 18 years. The Rare Pediatric Disease designationprogram allows for a sponsor who receives an approval for a product topotentially qualify for a voucher that can be redeemed to receive a priorityreview of a subsequent marketing application for a different product. We havepartnered with UCLA to lead U.S. clinical development efforts for the IMOprogram and anticipate that UCLA will serve as the lead U.S. clinical site forIMO. We intend to file an IND for IMO and commence our clinical trial in thefourth quarter of 2020.

Danon disease is a multi-organ lysosomal-associated disorder leading to earlydeath due to heart failure. Danon disease is caused by mutations in the geneencoding lysosome-associated membrane protein 2 ("LAMP-2"), a mediator ofautophagy. This mutation results in the accumulation of autophagic vacuoles,predominantly in cardiac and skeletal muscle. Male patients often require hearttransplantation and typically die in their teens or twenties from progressiveheart failure. Along with severe cardiomyopathy, other Danon disease symptomscan include skeletal muscle weakness, liver disease, and intellectualimpairment. There are no specific therapies available for the treatment of Danondisease. RP-A501 is in clinical trials as an in vivo therapy for Danon disease,which is estimated to have a prevalence of 15,000 to 30,000 patients in the U.S.and the EU, however new market research is being performed and the prevalence ofpatients may be updated in the future.

In January 2019, we announced the clearance of our IND application by the FDAfor RP-A501, and in February 2019, we were notified by the FDA that we weregranted Fast Track designation for RP-A501. University of California San DiegoHealth is the initial and lead center for our Phase 1 clinical trial.

On May 2, 2019, we presented additional preclinical data at the ASCGT annualmeeting, indicating that high VCN, in Danon disease-relevant organs in both miceand non-human primates ("NHN's"), with high concentrations in heart and livertissue (for NHP, cardiac VCN was approximately 10 times higher on average thanin skeletal muscle and central nervous system), which is consistent withreported results in several studies of heart tissue across different species.There were no treatment-related adverse events or safety issues up to thehighest dose. We have dosed three patients in the RP-A501 phase 1 clinicaltrial. We will continue further enrollment with clinical data read-outs in thefourth quarter of 2020.

As of March 2020, we have dosed three patients in the RP-A501 phase 1 clinicaltrial. This completes the first low dose cohort of the Phase 1 study. Based onthe preliminary safety and efficacy data review of this completed cohort, boththe FDA and IDMC has provided clearance to advance to a higher dose cohort inPhase 1 Trial of RP-A501 for Danon Disease. We will continue further enrollmentwith clinical data read-outs in the second half of 2020.

--------------------------------------------------------------------------------

In addition to its LVV and AAV programs, we also have a program evaluatingCRISPR/Cas9-based gene editing for FA. This program is currently in thediscovery phase. CRISPR/Cas9-based gene editing is a different method ofcorrecting the defective genes in a patient, where the editing is very specificand targeted to a particular gene sequence. "CRISPR/Cas9" stands for Clustered,Regularly Interspaced Short Palindromic Repeats ("CRISPR") Associated protein-9.The CRISPR/Cas9 technology can be used to make "cuts" in DNA at specific sitesof targeted genes, making it potentially more precise in delivering genetherapies than traditional vector-based delivery approaches. CRISPR/Cas9 canalso be adapted to regulate the activity of an existing gene without modifyingthe actual DNA sequence, which is referred to as gene regulation.

Strategy

We seek to bring hope and relief to patients with devastating, undertreated,rare pediatric diseases through the development and commercialization ofpotentially curative first-in-class gene therapies. To achieve these objectives,we intend to develop into a fully-integrated biotechnology company. In the near-and medium-term, we intend to develop our first-in-class product candidates,which are targeting devastating diseases with substantial unmet need, developproprietary in-house analytics and manufacturing capabilities and continue tocommence registration trials for our currently planned programs. In the mediumand long-term, we expect to submit our first biologics license applications("BLAs"), and establish our gene therapy platform and expand our pipeline totarget additional indications that we believe to be potentially compatible withour gene therapy technologies. In addition, during that time, we believe thatour currently planned programs will become eligible for priority review vouchersfrom the FDA that provide for expedited review. We have assembled a leadershipand research team with expertise in cell and gene therapy, rare disease drugdevelopment and commercialization.

We believe that our competitive advantage lies in our disease-based selectionapproach, a rigorous process with defined criteria to identify target diseases.We believe that this approach to asset development differentiates us as a genetherapy company and potentially provides us with a first-mover advantage.

Financial Overview

Since our inception, we have devoted substantially all of our resources toorganizing and staffing the Company, business planning, raising capital,acquiring or discovering product candidates and securing related intellectualproperty rights, conducting discovery, research and development activities forthe programs and planning for potential commercialization. We do not have anyproducts approved for sale and have not generated revenue from product sales.From inception through March 31, 2020, we raised net cash proceeds ofapproximately $373.1 million from investors through both equity and convertibledebt financing to fund operating activities. As of March 31, 2020, we had cash,cash equivalents and investments of $275.9 million.

Since inception, we have incurred significant operating losses. Our ability togenerate product revenue sufficient to achieve profitability will depend heavilyon the successful development and eventual commercialization of one or more ofthe current or future product candidates and programs. We had net losses of$24.7 million for the three months ended March 31, 2020 and $77.3 million forthe year ended December 31, 2019. As of March 31, 2020, we had an accumulateddeficit of $207.8 million. We expect to continue to incur significant expensesand higher operating losses for the foreseeable future as we advance our currentproduct candidates from discovery through preclinical development and clinicaltrials and seek regulatory approval of our product candidates. In addition, ifwe obtain marketing approval for any of their product candidates, we expect toincur significant commercialization expenses related to product manufacturing,marketing, sales and distribution. Furthermore, we expect to incur additionalcosts as a public company. Accordingly, we will need additional financing tosupport continuing operations and potential acquisitions of licensing or otherrights for product candidates.

Until such a time as we can generate significant revenue from product sales, ifever, we will seek to fund our operations through public or private equity ordebt financings or other sources, which may include collaborations with thirdparties and government programs or grants. Adequate additional financing may notbe available to us on acceptable terms, or at all. We can make no assurancesthat we will be able to raise the cash needed to fund our operations and, if wefail to raise capital when needed, we may have to significantly delay, scaleback or discontinue the development and commercialization of one or more productcandidates or delay pursuit of potential in-licenses or acquisitions.

Because of the numerous risks and uncertainties associated with productdevelopment, we are unable to predict the timing or amount of increased expensesor when or if we will be able to achieve or maintain profitability. Even if weare able to generate product sales, we may not become profitable. If we fail tobecome profitable or are unable to sustain profitability on a continuing basis,then we may be unable to continue our operations at planned levels and be forcedto reduce or terminate our operations.

Revenue

To date, we have not generated any revenue from any sources, including fromproduct sales, and we do not expect to generate any revenue from the sale ofproducts in the near future. If our development efforts for product candidatesare successful and result in regulatory approval or license agreements withthird parties, we may generate revenue in the future from product sales.

--------------------------------------------------------------------------------

Research and Development Expenses

Our research and development program ("R&D") expenses consist primarily ofexternal costs incurred for the development of our product candidates. Theseexpenses include:

expenses incurred under agreements with research institutions that conduct

research and development activities including, process development,

preclinical, and clinical activities on Rocket's behalf;

costs related to process development, production of preclinical and clinical

materials, including fees paid to contract manufacturers and manufacturing

input costs for use in internal manufacturing processes;

consultants supporting process development and regulatory activities; and

costs related to in-licensing of rights to develop and commercialize our

product candidate portfolio.

We recognize external development costs based on contractual payment schedulesaligned with program activities, invoices for work incurred, and milestoneswhich correspond with costs incurred by the third parties. Nonrefundable advancepayments for goods or services to be received in the future for use in researchand development activities are recorded as prepaid expenses.

Our direct research and development expenses are tracked on a program-by-programbasis for product candidates and consist primarily of external costs, such asresearch collaborations and third party manufacturing agreements associated withour preclinical research, process development, manufacturing, and clinicaldevelopment activities. Our direct research and development expenses by programalso include fees incurred under license agreements. Our personnel, non-programand unallocated program expenses include costs associated with activitiesperformed by our internal research and development organization and generallybenefit multiple programs. These costs are not separately allocated by productcandidate and consist primarily of:

Our research and development activities are central to our business model.Product candidates in later stages of clinical development generally have higherdevelopment costs than those in earlier stages of clinical development. As aresult, we expect that research and development expenses will increasesubstantially over the next several years as we increase personnel costs,including stock-based compensation, support ongoing clinical studies, seek toachieve proof-of-concept in one or more product candidates, advance preclinicalprograms to clinical programs, and prepare regulatory filings for productcandidates.

We cannot determine with certainty the duration and costs to complete current orfuture clinical studies of product candidates or if, when, or to what extent wewill generate revenues from the commercialization and sale of any of our productcandidates that obtain regulatory approval. We may never succeed in achievingregulatory approval for any of our product candidates. The duration, costs, andtiming of clinical studies and development of product candidates will depend ona variety of factors, including:

the scope, rate of progress, and expense of ongoing as well as any future

clinical studies and other research and development activities that we

undertake;

future clinical trial results;

uncertainties in clinical trial enrollment rates;

changing standards for regulatory approval; and

the timing and receipt of any regulatory approvals.

We expect research and development expenses to increase for the foreseeablefuture as we continue to invest in research and development activities relatedto developing product candidates, including investments in manufacturing, as ourprograms advance into later stages of development and as we conduct additionalclinical trials. The process of conducting the necessary clinical research toobtain regulatory approval is costly and time-consuming, and the successfuldevelopment of product candidates is highly uncertain. As a result, we areunable to determine the duration and completion costs of research anddevelopment projects or when and to what extent we will generate revenue fromthe commercialization and sale of any of our product candidates.

Our future research and development expenses will depend on the clinical successof our product candidates, as well as ongoing assessments of the commercialpotential of such product candidates. In addition, we cannot forecast with anydegree of certainty which product candidates may be subject to futurecollaborations, when such arrangements will be secured, if at all, and to whatdegree such arrangements would affect our development plans and capitalrequirements. We expect our research and development expenses to increase infuture periods for the foreseeable future as we seek to complete development ofour product candidates.

The successful development and commercialization of our product candidates ishighly uncertain. This is due to the numerous risks and uncertainties associatedwith product development and commercialization, including the uncertainty of:

--------------------------------------------------------------------------------

Table of Contents

the scope, progress, outcome and costs of our clinical trials and other

research and development activities;

the efficacy and potential advantages of our product candidates compared to

alternative treatments, including any standard of care;

the market acceptance of our product candidates;

obtaining, maintaining, defending and enforcing patent claims and other

intellectual property rights;

significant and changing government regulation; and

the timing, receipt and terms of any marketing approvals.

A change in the outcome of any of these variables with respect to thedevelopment of our product candidates that we may develop could mean asignificant change in the costs and timing associated with the development ofour product candidates. For example, if the FDA or another regulatory authoritywere to require us to conduct clinical trials or other testing beyond those thatwe currently contemplate for the completion of clinical development of any ofour product candidates that we may develop or if we experience significantdelays in enrollment in any of our clinical trials, we could be required toexpend significant additional financial resources and time on the completion ofclinical development of that product candidate.

General and Administrative Expenses

General and administrative ("G&A") expenses consist primarily of salaries andrelated benefit costs for personnel, including stock-based compensation andtravel expenses for our employees in executive, operational, finance, legal,business development, and human resource functions. In addition, othersignificant general and administrative expenses include professional fees forlegal, patents, consulting, investor and public relations, auditing and taxservices as well as other expenses for rent and maintenance of facilities,insurance and other supplies used in general and administrative activities. Weexpect general and administrative expenses to increase for the foreseeablefuture due to anticipated increases in headcount to support the continuedadvancement of our product candidates. We also anticipate that we will incurincreased accounting, audit, legal, regulatory, compliance and director andofficer insurance costs as well as investor and public relations expenses.

Interest Expense

Interest expense is related to the 2021 Convertible Notes, which mature inAugust 2021, and the 2022 Convertible Notes, which mature in August 2022.

Interest Income

Interest income is related to interest earned from investments.

Critical Accounting Policies and Significant Judgments and Estimates

Our consolidated financial statements are prepared in accordance with generallyaccepted accounting principles in the U.S. The preparation of our financialstatements and related disclosures requires us to make estimates and judgmentsthat affect the reported amounts of assets, liabilities, costs and expenses, andthe disclosure of contingent assets and liabilities in our financial statements.We base our estimates on historical experience, known trends and events andvarious other factors that we believe are reasonable under the circumstances,the results of which form the basis for making judgments about the carryingvalues of assets and liabilities that are not readily apparent from othersources. We evaluate estimates and assumptions on an ongoing basis. Actualresults may differ from these estimates under different assumptions orconditions.

Our significant accounting policies are described in more detail in our 2019Form 10-K, except as otherwise described below.

BrainStorm Leases a New Cleanroom Facility at The Tel Aviv Sourasky Medical Center to Manufacture NurOwn for The European Union – BioSpace

NEW YORK, N.Y., and TEL AVIV, Israel, May 07, 2020 (GLOBE NEWSWIRE) -- BrainStorm Cell Therapeutics Inc. (NASDAQ: BCLI), a leading developer of adult stem cell therapies for neurodegenerative diseases, announced today a lease agreement with the Tel Aviv Sourasky Medical Center (Sourasky) in Tel Aviv, Israel, to produce NurOwn in three state-of-the-art cleanrooms. The new facility will significantly increase the Companys capacity to manufacture and ship its product into the European Union and the local Israeli market.

About NurOwn NurOwn (autologous MSC-NTF) cells represent a promising investigational therapeutic approach to targeting disease pathways important in neurodegenerative disorders. MSC-NTF cells are produced from autologous, bone marrow-derived mesenchymal stem cells (MSCs) that have been expanded and differentiated ex vivo. MSCs are converted into MSC-NTF cells by growing them under patented conditions that induce the cells to secrete high levels of neurotrophic factors. Autologous MSC-NTF cells can effectively deliver multiple NTFs and immunomodulatory cytokines directly to the site of damage to elicit a desired biological effect and ultimately slow or stabilize disease progression. BrainStorm has fully enrolled a Phase 3 pivotal trial of autologous MSC-NTF cells for the treatment of amyotrophic lateral sclerosis (ALS). BrainStorm also recently received U.S. FDA acceptance to initiate a Phase 2 open-label multicenter trial in progressive MS and enrollment began in March 2019.

Chinas scientists accused of playing God by creating monstrous cloned apes and primates with human organs – The Sun

CHINESE scientists have been accused of being real-life Dr Frankensteins who play God by cloning apes and editing the genes of babies.

Some of their work has been dubbed monstrous while other cutting edge research could lead to cures for Parkinson's and Alzheimer's.

4

It's important to note that the US and the UK are not immune from conducting tests on animals and in fact carry out THOUSANDS of experiments on primates every year.

However, China has become the capital of research on apes and monkeys believing that our closest relatives hold the key to understanding brain disorders that destroy lives.

Incredibly, the Institute of Neuroscience (ION) in Shanghai, cloned five infant monkeys last year from an adult macaque who had been genetically-edited.

The result was baby primates intentionally born with a mutation that disrupts their wake-sleep cycle.

By giving the monkeys new drugs to treat their pre-existing brain disorders, the scientists hope to develop treatments for illnesses such as Alzheimer's disease.

It's no wonder the ION has been dubbed the "Cern of primate neurobiology".

The Institute successfully cloned two macaque monkeys in 2018 - a world first giving the experts confidence to push ahead with further experiments.

4

Heaping praise on the research, the Chinese Academy of Sciences said: "The achievement heralds a new era in which China can produce batches of standardised monkey clones, which will serve as animal models in the research of the brain's cognitive functions, early diagnoses and interventions of diseases, as well as research and development of drugs.

While China allows genetic manipulation on animals it has banned the use of gene-editing on humans but that hasn't stopped some of its scientists "playing God" with unborn children.

Scientist He Jiankui, 35, rocked the scientific world when he revealed he had altered the embryos of twin girls in 2018.

In December last year, it was revealed that a third child born to a different mum had also been gene-edited.

The rogue expert said he used a tool called Crispr to disable a gene that allows the AIDS virus to enter cells in a bid to make the children immune from the disease.

But why have such experiments been dubbed monstrous by others within the scientific community?

Experts claim gene-editing in people could "divide humans into subspecies" and can cause mutations, genetic problems and even cancer.

Dr Kiran Musunuru, an expert in this area from the University of Pennsylvania, called the experiment unconscionable an experiment on human beings that is not morally or ethically defensible.

4

Professor Julian Savulescu, of the University of Oxford, said: If true, this experiment is monstrous.

The embryos were healthy. No known diseases. Gene editing itself is experimental and is still associated with off-target mutations, capable of causing genetic problems early and later in life, including the development of cancer.

There are many effective ways to prevent HIV in healthy individuals: for example, protected sex.

Last December, Mr Jiankui was jailed for three years after news of the third child's birth was revealed.

He was convicted of practising medicine without a licence and fined 330,000 by a court in Shenzhen, the Xinhua news agency reported.

One of the most controversial experiments to date was the creation of embryos that were part human and part primate.

Last year, Spaniard Juan Carlos Izpisa Belmonte led a team of Chinese researchers with the end goal of creating monkeys which have entirely human organs such as kidneys or livers.

The organs will then be used for human transplants.

Based in China, the team made the chimeras a single organism with cells from more than one genotype - by injecting human stem cells into a fresh monkey embryo.

Biologist Belmonte previously tried adding human cells to embryos of pigs but the disturbing experiment was not successful.

However, because primates are genetically related to humans, the chances of the new research being successful is much greater.

The scientists also use gene-editing technology to disable certain cell formations in the animals to give the human cells a better chance of thriving.

4

In the US and other western democracies, such research is banned however in China, experts are allowed to push the boundaries of scientific ethics.

Importantly, no Frankenstein monster has been born as a result of this research... not yet anyway.

Instead, the hybrid embryos are allowed to develop for around two weeks so their progress can be studied.

Mr Belmonte defended his work with the Chinese, saying: History shows us time and time again that, over time, our ethical and moral standards change and mutate, like our DNA, and what yesterday was ethically unacceptable, if this really represents an advance for the progress of humanity, today it is already an essential part of our lives."

A similar experiment involved two piglets who were born with monkey cells in December at the State Key Laboratory of Stem Cell and Reproductive Biology in Beijing.

The so-called 'pig-monkey chimeras' died a week later.

Away from China, one of the most sinister experiments took place at the University of Munich where two monkeys were given transplanted pig hearts.

The poor creatures died after six months in a study which was deemed a success.

Roeland Nusse receives Canada’s Gairdner International Award | The Dish – Stanford University News

by Krista Conger on May 6, 2020 3:43 pm

ROELAND NUSSE, professor of developmental biology, has received Canadas Gairdner International Awardfor his work on understanding the role of the Wnt signaling pathway in normal development and in cancer.

The Wnt pathway is made up of proteins, including one called Wnt, that transmit signals from outside the cell to the inside to trigger biological functions including gene expression and cell division.

Roeland Nusse was honored with Canadas Gairdner International Award for his work on the Wnt signaling pathway, which plays an important role in normal development and in cancer. (Image credit: Norbert von der Groeben)

The award recognizes excellence in fundamental research that affects human health.

Recipients receive 100,000 Canadian dollars (about $72,000) to use as they wish; Nusse plans to donate his award toUNICEF to help provide protective equipment for health care workers caring for children amid the global COVID-19 pandemic. Nusse is the Reed-Hodgson Professor in Human Biology and the Virginia and Daniel K. Ludwig Professor in Cancer Research.

In 1982, Nusse collaborated withHarold Varmus, then a professor in microbiology and immunology at the University of California, San Francisco, to identify Wnt as a critical cancer-associated gene in a mouse model of breast cancer. Nusse went on to show that the analogous gene in fruit flies, Wingless, plays an important role in regulating normal development. The finding highlighted the connections between normal development and cancer.

More recently, Nusse has focused his research on understanding how Wnt signaling regulates the activity of tissue-specific adult stem cells in response to injury or disease. In 2016, Nusse was awarded a $3million Breakthrough Prizefor his work on Wnt signaling.

Broad Foundation brings together stem cell scientists, engineers and physicians at University of Southern – Mirage News

The Broad Foundation brings together stem cell scientists, engineers and physicians at USC and beyond

Developing new stem cell therapies requires more than a solo biologist having a eureka moment alone in the lab. Real progress relies on collaborations between biologists, engineers and physicians. Thats why The Eli and Edythe Broad Foundation has continued its support of two strategic initiatives: innovation awards bringing together teams of engineers and scientists from USC and Caltech, and clinical research fellowships for physician-scientists.

Engineering new approaches: The Broad Innovation Awards

For the fifth consecutive year, the Broad Innovation Awards are providing critical funding to USC-affiliated faculty members pursuing multi-investigator research collaborations related to stem cells. For the first year, these collaborations are also drawing on the expertise of biomedical engineers from Caltech. Each award provides $200,000 of funding for a one-year project.

Were very excited to be joining our colleagues at USC in pioneering new approaches to advancing stem cell research, said Stephen L. Mayo, chair of the Division of Biology and Biological Engineering at Caltech. Were thankful to The Broad Foundation for supporting cross-town collaborations between scientists with different expertise but common goals.

With support from a Broad Innovation Award, Andy McMahon, the director of the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC, is collaborating with Caltech biomedical engineer Long Cai to leverage a new technology for understanding chronic kidney disease. The technology, called seqFISH, provides information about genetic activity taking place in intact tissueenabling the study of the interactions between cells in their native environments.

Dr. Cais seqFISH technology will provide an unprecedented insight into the cellular interplay underlying chronic kidney disease caused by a maladaptive response to acute kidney injury, said McMahon, who is the W.M. Keck Provost and University Professor of Stem Cell Biology and Regenerative Medicine, and Biological Sciences, as well as the chair of the Department of Stem Cell Biology and Regenerative Medicine at USC. We aim to better understand this maladaptive responsewhich is more common in malesin order to find new targets for preventing the progression to chronic kidney disease.

A second Broad Innovation Award brings together USC Stem Cell scientist Rong Lu and Caltech synthetic biologist Michael Elowitz. Their team will study the spatial organization of blood-forming stem and progenitor cells, also called hematopoietic stem and progenitor cells (HSPCs), which reside in the bone marrow. By pinpointing the locations of specific HSPCs, the scientists may find clues to explain why certain HSPCs are so dominantreplenishing the majority of the bodys blood and immune cells after a disruption such as a bone marrow transplantation.

Spatial advantages may be the primary drivers of what we refer to as the clonal dominance of certain HSPCs, said Lu, a Richard N. Merkin Assistant Professor of Stem Cell Biology and Regenerative Medicine, Biomedical Engineering, Medicine, and Gerontology at USC. Understanding the spatial competition between HSPCs could help improve bone marrow transplantation and provide new insights into aging and the development of diseases such as leukemiawhich are associated with clonal dominance.

Elowitz added: Thanks to the Broad Innovation Award and this exciting collaboration with Rong Lu, we will be able to bring a new, synthetic biology approach to record cell histories and read them out in individual cells within their native spatial context, providing new insights into fundamental questions in blood stem cell development.

A third Broad Innovation Award brings together three collaborators at USC: Michael Bonaguidi, an assistant professor of stem cell biology and regenerative medicine, biomedical engineering, and gerontology; Robert Chow, a professor of physiology and neuroscience, and biomedical engineering; and Jonathan Russin, an assistant professor of neurological surgery and associate surgical director for the USC Neurorestoration Center. Their project focuses on finding new approaches to treating epilepsy by studying neural cells called astroglia. These cells perform a variety of key functions that support the health of neurons in the brain, and they may also play a role in modulating epileptic seizures.

Although adults dont tend to generate many new brain cells, humans do produce a limited number of new astroglia, said Bonaguidi. We will examine these newborn astroglia at the single-cell level to better understand their role in epileptic patients, and to lay the groundwork for identifying new treatments.

The doctors are in: The Broad Clinical Research Fellowships

The Broad Clinical Research Fellowships are also entering their fifth consecutive year. These fellowships support stem cell research by physician-scientists and residents who intend to practice medicine in California.

These fellowships provide a very special opportunity for our medical residents to engage deeply in laboratory research, as a complement to their extensive training in patient care, said Laura Mosqueda, Dean of the Keck School of Medicine of USC. This valuable research experience gives them a much more complete perspective on how to meet the challenges of finding the best possible treatments for their patients.

A USC resident physician in general surgery, Kemp Anderson will spend his fellowship studying necrotizing enterocolitis, a very serious intestinal infection that affects nearly 10 percent of premature infants. Specifically, he will explore how a molecule involved in cellular communication, called farnesoid X receptor, or FXR, might contribute to this disease.

If FXR plays a role in compromising intestinal barrier function in these premature infants, then altering the activity of FXR could potentially yield treatment modalities for necrotizing enterocolitis, avoiding the morbidity and mortality associated with surgical intervention, said Anderson, who is performing the research under the mentorship of Christopher Gayer and Mark Frey at Childrens Hospital Los Angeles (CHLA). Im deeply appreciative of the benefactors and the selection committee for awarding me the Broad Clinical Fellowship, as it is allowing me devoted time to focus on this important project, and to become a more well-rounded physician through this academic pursuit.

Brittany Rocque, a resident physician in general surgery, will use her fellowship to seek better ways to predict, detect and diagnose immune rejection in patients who have undergone liver transplantation. Nearly 60 percent of pediatric patients and at least 15 percent of adult patients reject their liver transplants, and this can currently only be confirmed through an invasive surgical biopsy. Rocque is utilizing the technology Imaging Mass Cytometry to identify and analyze the types of immune cells involved in rejection.

My project has the potential to provide a noninvasive option to assess rejection in transplanted patients, and to expand our understanding of immune rejection, said Rocque, who is being co-mentored by Juliet Emamaullee and Shahab Asgharzadeh at CHLA. Im greatly looking forward to applying my passion for transplantation surgery in the context of basic science, and enhancing my appreciation for the nuances of research, thanks to the Broad Clinical Research Fellowship.

A hematology-oncology fellow who will be transitioning to a junior faculty position at USC next year, Caitlin ONeill will study a condition known as clonal hematopoiesis or CH, a phenomenon common in the aging population. CH involves genetic mutations that cause the expansion of a particular population of blood cells without leukemia or related malignancies. CH increases risks for certain health conditions including heart disease.

During her Broad Clinical Research Fellowship, ONeill will look at one mutation seen in patients with CH: a mutation to the gene called Tet methylcytosine dioxygenase 2, or TET2. ONeill will explore if this mutation promotes blood clots, inflammation and heart disease.

The goal is to inform therapies to prevent heart disease and leukemic progression in aging patients with CH, said ONeill, who is working with co-mentors Casey OConnell and Rong Lu at USC. Im very happy to be working on this project, with support from the Broad Clinical Research Fellowship, during my transition to becoming a faculty member at USC.

Schizophrenia drug points to improved brain cancer radiation therapy – New Atlas

Promising new research from the University of California, Los Angeles (UCLA), suggests an old schizophrenia drug could significantly enhance the efficacy of radiation treatment for one of the deadliest forms of brain cancer.

The general treatment process for glioblastoma, the deadliest adult brain cancer, is surgery followed by radiation therapy alongside a drug called temozolomide. This current standard-of-care still results in a nearly 95-percent mortality rate and, although radiation therapy does generally extend median survival duration, it can result in a dispiriting catch-22 scenario.

Compared to surgery alone, radiation therapy for glioblastoma extends survival duration by up to six months. However, radiation can also trigger a process called phenotype conversion, making it more likely the cancer will ultimately reoccur.

Phenotype conversion occurs when radiation therapy triggers a transformation in non-tumor stem cells, turning them into glioma-initiating cells. The goal of the new research was to find a pharmacological way to stop radiation initiating this phenotype conversion.

The first step was screening 83,000 different compounds to find a molecule that could effectively cross the blood-brain barrier and inhibit radiation-induced phenotype conversion. An old anti-psychotic drug called trifluoperazine, developed in the 1950s to treat schizophrenia, arose as a promising candidate.

The next step was conducting expansive animal tests to see if the drug, combined with radiation therapy, extended general survival rates. The results were incredibly promising, with all drug-treated animals surviving past 200 days, compared to a 67-day survival rate in the animals treated only with radiation.

Many preclinical glioblastoma studies report fairly small increases in overall survival in mice, and that rarely translates into benefits for patients, explains Frank Pajonk, senior author on the new study. But here we see pretty drastic effects in improved overall survival, and I find that very encouraging. It gives us hope that this is all going to translate into a benefit for people.

These very significant animal results suggest a straightforward combination of these two treatments could dramatically increase survival rates for human patients with glioblastoma. As the drug is already FDA-approved for clinical use, the researchers suggest human trials could commence as soon as later this year.

While radiotherapy is one of the few treatments that prolong survival in glioblastoma patients, radiation alone does very little in treating the disease in our models because we are dealing with highly aggressive tumors, says Pajonk. The drug trifluoperazine by itself does not do much either, but we found when you combine them, they become highly efficient. Importantly, the drug does not sensitize cells to radiation but rather prevents the occurrence of resistant glioma stem cells.

It is unclear exactly how the drug prevents phenotype conversion in the face of radiation, but the researchers hypothesize it is due to the nature of its dopamine receptor antagonism. Trifluoperazine is not commonly used in clinical practice nowadays as newer dopamine receptor antagonists have taken its place in psychiatric treatments, due to better efficacy and lower negative side effects.

I think we can find a combination of treatments with radiation that is very tolerable to patients and can do well, says Leia Nghiemphu, principal investigator on the upcoming clinical trial. The next step is to see if we can stop this resistance to radiation in humans.

The new study was published in the journal PNAS.

Scientists finally explained one of the strangest coronavirus symptoms – BGR

One of the qualities of the novel coronavirus that makes it so dangerous is that it doesnt have many specific symptoms that are telltale signs of an infection. Instead, the most common symptoms include signs that present with other viral infections, including the flu. Fever, cough, and shortness of breath might make you think youve been infected, but it can be something else entirely. The sudden loss of taste or smell is the closest thing we have to a telltale COVID-19 symptom, but it doesnt present itself in all those infected.

Other symptoms that can appear in COVID-19 cases can include sore throat, headache, muscle pain, and chills, but these can also develop in other conditions. Then there are gastrointestinal symptoms, including diarrhea and vomiting. The CDC doesnt include them in the list of COVID-19 symptoms but does mention that children might experience them. These gastrointestinal symptoms are unusual for respiratory diseases, but researchers have finally explained why it happens.

Scientists from Hubrecht Institute in Utrecht, Erasmus MC University Medical Center Rotterdam, and Maastricht University in the Netherlands have been able to grow an artificial gut (an organoid) from adult stem cells. they then tried to infect it with the SARS-CoV-2 virus that causes the COVID-19 disease. The researchers discovered that the virus can bind to epithelial cells of the intestine by hooking up to the same ACE2 receptor that lets them enter the lungs. They published their findings in Science Magazine.

Once these cells are invaded, the virus can continue to replicate and increase in number just like it does in the lungs. Moreover, the whole thing starts generating an immune response when the body detects the pathogen. These organoids contain the cells of the human intestinal lining, making them a compelling model to investigate infection by SARS-CoV-2, Hubrecht Institutes Hans Clevers told SciTech Daily.

Gastrointestinal symptoms can appear in up to one-third of COVID-19 patients, the report notes. There are worries that the virus can spread via fecal-oral transmission. Also, other studies theorized that fecal aerosols in bathrooms could infect other people.

Using electron microscopy, the scientists were able to determine the presence of the virus on gastrointestinal cells and found them replicating over time. The white regions in the image above indicate the presence of the coronavirus inside the cells of the organoid, which is colored in blue and green.

The researchers discovered that the virus can enter cells regardless of the level of ACE2 receptors. Even cells with low levels of ACE2 may become the host of replication for the virus. The researchers also looked at the response of the intestinal cells with RNA sequencing. They found that interferon-stimulated genes are activated after an infection, or genes that are known to fight a viral infection.

The observations made in this study provide definite proof that SARS-CoV-2 can multiply in cells of the gastrointestinal tract, Erasmus MCs Bart Haagmans told the blog. However, we dont yet know whether SARS-CoV-2, present in the intestines of COVID-19 patients, plays a significant role in transmission. Our findings indicate that we should look into this possibility more closely.

While the new study is definitely interesting, its unclear what sort of viral concentration in food is required to lead to diarrhea and nausea. Also, its unclear how infectious patients showing such symptoms are for other people. Not to mention that the research cant explain how fast the immune system would clear the gut. But the study proves yet again that good hygiene is of utmost importance whether theres an epidemic around or not.

On a related note, weve discussed before that ordering food from restaurants is safe even if said food is covered with the novel coronavirus. Thats because COVID-19 is a viral disease, and serious complications can arise only after the lungs are infected. Moreover, the actual cooking of food will also destroy all traces of the virus, which is why you should reheat your food at home if you want to be extra safe.

What Do New Neurons in the Brains of Adults Actually Do? – The Scientist

In the spring of 2019, neuroscientist Heather Cameron set up a simple experiment. She and her colleagues put an adult rat in the middle of a plastic box with a water bottle at one end. They waited until the rat started drinking and then made a startling noise to see how the animal would respond. The team did this repeatedly with regular rats and with animals that were genetically altered so that they couldnt make new neurons in their hippocampuses, a brain region involved in learning and memory. When the animals heard the noise, those that could make new hippocampal neurons immediately stopped slurping water and looked around, but the animals lacking hippocampal neurogenesis kept drinking. When the team ran the experiment without the water bottle, both sets of rats looked around right away to figure out where the sound was coming from. Rats that couldnt make new neurons seemed to have trouble shifting their attention from one task to another, the researchers concluded.

Aging humans, in whom neurogenesis is thought to decline, often have trouble remembering details that distinguish similar experiences.

Its a very surprising result, says Cameron, who works at the National Institute of Mental Health (NIMH) in Bethesda, Maryland. Researchers studying neurogenesis in the adult hippocampus typically conduct experiments in which animals have had extensive training in a task, such as in a water maze, or have experienced repetitive foot shocks, she explains. In her experiments, the rats were just drinking water. It seemed like there would be no reason that the hippocampus should have any role, she says. Yet in animals engineered to lack hippocampal neurogenesis, the effects are pretty big.

The study joins a growing body of work that challenges the decades-old notion that the primary role of new neurons within the adult hippocampus is in learning and memory. More recently, experiments have tied neurogenesis to forgetting, one possible way to ensure the brain doesnt become overloaded with information it doesnt need, and to anxiety, depression, stress, and, as Camerons work suggests, attention. Now, neuro-scientists are rethinking the role that new neurons, and the hippocampus as a whole, play in the brain.

Most of the research into neurogenesis involves boosting or inhibiting animals generation of new neurons, then training animals on a complex memory task such as finding a treat in a maze, and later retesting the animals. Decreasing neurogenesis tends to hamper the animals ability to remember.

Alzheimers disease, Parkinsons disease

Training mice or rats on a memory task before manipulating neurogenesis has also been found to affect the strength of the trained memory. Boosting neurogenesis reduced the memorys strength, perhaps an extreme form of forgetting that at normal levels avoids the remembering of unnecessary details.

Alzheimers disease and other forms of dementia

Research has linked decreased neurogenesis with more anxious and depressive behaviors in mice. Stress can reduce neurogenesis, ultimately leading mice to be more anxious in future stressful situations.

PTSD, anxiety, depression

Research has linked decreased neurogenesis with trouble switching focus.

Autism

The first hint that adult animal brains may make new neurons appeared in the early 1960s, when MIT neurobiologist Joseph Altman used radioactive labeling to track the proliferation of nerve cells in adult rats brains.Other data published in the 1970s and 1980s supported the conclusion, and in the 1990s, Fred Rusty Gage and his colleagues at the Salk Institute in La Jolla, California, used an artificial nucleotide called bromodeoxyuridine (BrdU) to tag new neurons born in the brains of adult rats and humans. Around the same time, Elizabeth Gould of Princeton University and her collaborators showed that adult marmoset monkeys made new neurons in their hippocampuses, specifically in an area called the dentate gyrus. While some researchers questioned the strength of the evidence supporting the existence of adult neurogenesis, most of the field began to shift from studying whether adult animal brains make new neurons to what role those cells might play.

In 2011, Ren Hen at Columbia University and colleagues created a line of transgenic mice in which neurons generated by neuro-genesis survived longer than in wildtype mice. This boosted the overall numbers of new neurons in the animals brains. The team then tested the modified mices cognitive abilities. Boostingnumbers of newly born neurons didnt improve the mices performances in water mazes or avoidance tasks compared with control mice. But it did seem to help them distinguish between two events that were extremely similar. Mice with more new neurons didnt freeze as long as normal mice when put into a box that was similar to but not exactly the same as one in which theyd experienced a foot shock in earlier training runs.

These results dovetailed with others coming out at the time, particularly those showing that aging humans, in whom neurogenesis is thought to decline, often have trouble remembering details that distinguish similar experiences, what researchers call pattern separation. The line of thinking is that the memories that are most likely to be impacted by neurogenesis are memories that are really similar to each other, says Sarah Parylak, a staff scientist in Gages lab at the Salk Institute.

As insights into pattern separation emerged, scientists were beginning to track the integration of new rodent neurons into existing neural networks. This research showed that new neurons born in the dentate gyrus had to compete with mature neurons for connections to neurons in the entorhinal cortex (EC), a region of the brain with widespread neural networks that play roles in memory, navigation, and the perception of time. (See Memories of Time on page 32.) Based on detailed anatomical images, new dentate gyrus neurons in rodents appeared to tap into preexisting synapses between dentate gyrus neurons and EC neurons before creating their own links to EC neurons.

To continue exploring the relationship between old and new neurons, a group led by the Harvard Stem Cell Institutes Amar Sahay, who had worked with Hen on the teams 2011 study, wiped out synapses in the dentate gyruses of mice. The researchers overexpressed the cell deathinducing protein Krppel-like factor 9 in young adult, middle-aged, and old mice to destroy neuronal dendritic spines, tiny protrusions that link up to protrusions of other neurons, in the brain region. Those lost connections led to increased integration of newly made neurons, especially in the two older groups, which outperformed age-matched, untreated mice in pattern-separation tasks. Adult-born dentate gyrus neurons decrease the likelihood of reactivation of those old neurons, Sahay and colleagues concluded, preventing the memories from being confused.

Parylak compares this situation to going to the same restaurant after it has changed ownership. In her neighborhood in San Diego, theres one location where shes dined a few times when the restaurant was serving different cuisine. Its the same location, and the building retains many of the same features, so the experiences would be easy to mix up, she says, but she can tell them apart, possibly because of neurogenesiss role in pattern separation. This might even hold true for going to the same restaurant on different occasions, even if it served the same food.

Thats still speculative at this point. Researchers havent been able to watch neurogenesis in action in a living human brain, and its not at all clear if the same thing is going on there as in the mouse brains they have observed. While many scientists now agree that neurogenesis does occur in adult human brains, there is little consensus about what it actually does. In addition to the work supporting a role for new neurons in pattern separation, researchers have accumulated evidence that it may be more important for forgetting than it is for remembering.

In recent years, images and videos taken with state-of-the-art microscopy techniques have shown that new neurons in the dentate gyrus of the hippocampus go through a series of changes as they link up to existing networks in the brain.

A neural stem cell divides to generate a new neuron (green).

As the new neuron grows, it rotates from a horizontal to a vertical position and connects to an interneuron (yellow) in a space called the hilus that sits within the curve of the dentate gyrus. The young neuron also starts making connections with well-established dentate gyrus neurons (blue) as well as neurons in the hippocampus (red).

Once connections are formed, mature neurons send signals into the new neuron, and the cell starts firing off more of its own signals. At around four weeks of age, the adult-born neuron gets hyperexcited, sending electrical signals much more often than its well-established neuronal neighbors do.

As the new neuron connects with still more neurons, interneurons in the hilus start to send it signals to tamp down its activity.

It seems counterintuitive for neurogenesis to play a role in both remembering and forgetting, but work by Paul Frankland of the Hospital for Sick Children Research Institute in Toronto suggests it is possible. In 2014, his team showed that when mice made more new neurons than normal, they were more forgetful. He and his colleagues had mice run on wheels to boost levels of neurogenesis, then trained the animals on a learning task. As expected, they did better than control mice who hadnt exercised. (See How Exercise Reprograms the Brain, The Scientist, October 2018.) In other animals, the researchers boosted neurogenesis after the mice learned information thought to be stored, at least in the short term, in the hippocampus. When we did that, what we found was quite surprising, Frankland says. We found a big reduction in memory strength.

His team was puzzled by the result. Adding to the confusion, the researchers had observed a larger effect in memory impairment with mice that learned, then exercised, than they had seen in memory improvement when the mice ran first and then learned. As he dug into the literature, Frankland realized the effect was what other neuroscientists had called forgetting. He found many theoretical papers based on computational modeling that argued that as new neurons integrate into a circuit, the patterns of connections in the circuit change, and if information is stored in those patterns of connections, that information may be lost. (See Memory Munchers on page 21.)

The notion surprised other neuroscientists, mainly because up to that point theyd had two assumptions related to neurogenesis and forgetting. The first was that generating new neurons in a normal animal should be good for memory. The second was that forgetting was bad. The first assumption is still true, Frankland says, but the second is not. Many people think of forgetting as some sort of failure in our memory systems, he explains. Yet in healthy brains theres tons of forgetting happening all of the time. And, in fact, its important for memory function, Frankland says. It would actually be disadvantageous to remember everything we do.

Experiments have tied neurogenesis to forgetting, anxiety, depression, stress, and attention.

Parylak says this idea of forgetting certainly has provoked a lot of discussion. Its unclear, for example, whether the mice in Franklands experiments are forgetting, or if they are identifying a repeat event as something novel. This is the point, she explains, where doing neurogenesis research in humans would be beneficial. You could ask a person if theyd actually forgotten or if they are making some kind of extreme discrimination.

Despite the questions regarding the results, Frankland and his colleagues continued their work, testing mices forgetfulness with all types of memories, and more recently they asked whether the forgetting effect jeopardized old and new memories alike. In experiments, his team gave mice a foot shock, then boosted hippocampal neurogenesis (with exercise or a genetic tweak to neural progenitor cells), and put the mice in the same container theyd been shocked in. With another group of mice, the researchers waited nearly a month after the foot shock before boosting neurogenesis and putting the mice back in the container. Boosting the number of new neurons, the team found, only weakened the newly made memory, but not one that had been around for a while. This makes a lot of sense, Frankland says. As our memories of everyday events gradually get consolidated, they become less and less dependent on the hippocampus, and more dependent on another brain region: the cortex. This suggests that remote memories are less sensitive to changes in hippocampal neurogenesis levels.

The hippocampus tracks whats happened to you, Frankland says. Much of thats forgotten because much of it is inconsequential. But every now and then something interesting seems to happen, and its these eventful memories that seem to get backed up in other areas of the brain.

Researchers think neurogenesis helps the brain distinguish between two very similar objects or events, a phenomenon called pattern separation. According to one hypothesis, new neurons excitability in response to novel objects diminishes the response of established neurons in the dentate gyrus to incoming stimuli, helping to create a separate circuit for the new, but similar, memory.

At NIMH, one of Camerons first studies looking at the effects of neurogenesis tested the relationship between new neuronal growth and stress. She uncovered the connection studying mice that couldnt make new neurons and recording how they behaved in an open environment with food at the center. Just like mice that could still make new neurons, the neuro-genesis-deficient mice were hesitant to go get the food in the open space, but eventually they did. However, when the animals that couldnt make new neurons were stressed before being put into the open space, they were extremely cautious and anxious, whereas normal mice didnt behave any differently when stressed.

Cameron realized that the generation of new neurons also plays a role in the brain separate from the learning and memory functions for which there was growing evidence. In her experiments, we were looking for memory effects and looked for quite a while without finding anything and then stumbled onto this stress effect, she says.

The cells in the hippocampus are densely packed with receptors for stress hormones. One type of hormone in particular, glucocorticoids, is thought to inhibit neurogenesis, and decreased neurogenesis has been associated with depression and anxiety behaviors in rodents. But there wasnt a direct link between the experience of stress and the development of these behaviors. So Cameron and her colleagues set up an experiment to test the connection.

When the team blocked neurogenesis in adult mice and then restrained the animals to moderately stress them, their elevated glucocorticoid levels were slow to recover compared with mice that had normal neurogenesis. The stressed mice that could not generate new neurons also acted oddly in behavioral tests: they avoided food when put in a new environment, became immobile and increasingly distressed when forced to swim, and drank less sugary water than normal mice when it was offered to them, suggesting they dont work as hard as normal mice to experience pleasure. Impaired adult neurogenesis, the experiments showed, played a direct role in developing symptoms of depression, Cameron says.

The notion that neurogenesis and stress might be tied directly to our mental states led Cameron to look back into the literature, where she found many suggestions that the hippocampus plays a role in emotion, in addition to learning and memory. Even Altman, who unexpectedly identified neurogenesis in adult rodents in the 1960s, and colleagues suggested as much in the 1970s. Yet the argument has only appeared sporadically in the literature since then. Stress is complicated, Cameron says; its hard to know exactly how stressful experiences affect neurogenesis or how the generation of new neurons will influence an animals response to stress. Some types of stress can decrease neurogenesis while others, such as certain forms of intermittent stress, can increase new neuronal growth. Last year, Cameron and colleagues found that generating new neurons helps rats used to model post-traumatic stress disorder recover from acute and prolonged periods of stress.

Neurogenesis appears to play a role in both remembering and forgetting.

Her work has also linked neurogenesis to other characteristics of rodent behavior, including attention and sociability. In 2016, with Gould at Princeton and a few other collaborators, she published work suggesting that new neurons are indeed tied to social behavior. The team created a hierarchy among rats, and then deconstructed those social ranks by removing the dominant male. When the researchers sacrificed the animals and counted new neurons in their brains, the rats from deconstructed hierarchies had fewer new neurons than those from control cages with stable ranks. Rats with uncertain hierarchies and fewer new neurons didnt show any signs of anxiety or reduced cognition, but they werent as inclined as control animals to spend time with new rats put into their quarters, preferring to stick with the animals they knew. When given a drugoxytocinto boost neurogenesis, they once again began exploring and spending time with new rats that entered their cages.

The study from Camerons lab on rats ability to shift their attention grew out of the researchers work on stress, in which they observed that rodents sometimes couldnt switch from one task to the next. Turning again to the literature, Cameron found a study from 1969 that seemed to suggest that neurogenesis might affect this task-switching behavior. Her team set up the water bottle experiments to see how well rats shifted attention. Inhibiting neurogenesis in the adult mice led to a 50 percent decrease in their ability to switch their focus from drinking to searching for the source of the sound.

This paper is very interesting, says J. Tiago Gonalves, a neuroscientist at Albert Einstein College of Medicine in New York who studies neurogenesis but was not involved in the study. It could explain the findings seen in some behavioral tasks and the incongruences between findings from different behavioral tasks, he writes in an email to The Scientist. Of course, follow-up work is needed, he adds.

Cameron argues that shifting attention may be yet another behavior in which the hippocampus plays an essential role but that researchers have been overlooking. And there may be an unexplored link between making new neurons and autism or other attention disorders, she says. Children with autism often have trouble shifting their attention from one image to the next in behavioral tests unless the original image is removed.

Its becoming clear, Cameron continues, that neurogenesis has many functions in the adult brain, some that are very distinct from learning and memory. In tasks requiring attention, though, there is a tie to memory, she notes. If youre not paying attention to things, you will not remember them.

Many, though not all, neuroscientists agree that theres ongoing neurogenesis in the hippocampus of most mammals, including humans. In rodents and many other animals, neurogenesis has also been observed in the olfactory bulbs. Whether newly generated neurons show up anywhere else in the brain is more controversial.

There had been hints of new neurons showing up in the striatum of primates in the early 2000s. In 2005,Heather Cameronof the National Institute of Mental Health and colleagues corroborated those findings, showing evidence of newly made neurons in therat neocortex, a region of the brain involved in spatial reasoning, language, movement, and cognition, and in the striatum, a region of the brain involved in planning movements and reacting to rewards, as well as self-control and flexible thinking (J Cell Biol, 168:41527). Nearly a decade later, using nuclear-bomb-test-derivedcarbon-14 isotopesto identify when nerve cells were born,Jonas Frisnof the Karolinska Institute in Stockholm and colleagues examined the brains of postmortem adult humans and confirmed thatnew neurons existed in the striatum(Cell, 156:107283, 2014).

Those results are great, Cameron says. They support her idea that there are different types of neurons being born in the brain throughout life. The problem is theyre very small cells, theyre very scattered, and therere very few of them. So theyre very tough to see and very tough to study.

Acute Myeloid Leukemia Therapeutics Market Latest Innovations, Drivers and Industry Key Events During Forecast 2017 2025 – Jewish Life News

Leukemia are a heterogeneous group of cancers affecting the bone marrow and White Blood Cells (WBC). Leukemia is characterized by the rapid increase of abnormal blood cells growth or blasts, resulting in a decrease in the numbers of healthy, normal fully modified blood cells, leading to the typical symptoms of bleeding, anemia, and high risk of infection. Leukemia can grow along either the myeloid or lymphoid stem cell lines, it depends on the effect of genetic and epigenetic mutations on the progression of pluripotent stem cells to the various lines of mature cells which then pass into the blood. The effected line, combined with the rate of action and growth of disease reflects the four types of leukemias- Acute Myeloid Leukemia (AML), chronic lymphoblastic leukemia, chronic myeloid leukemia, acute lymphoblastic leukemia. AML: Acute Myeloid Leukemia, is a serious condition, its the most common leukemia suffered by adult people.
