'''David Baltimore''' (born March 7, 1938) is an American [[biologist]], [[university administrator]], and 1975 [[Nobel Prize in Physiology or Medicine|Nobel laureate in Physiology or Medicine]]. He is a professor of biology at the [[California Institute of Technology]] (Caltech), where he served as president from 1997 to 2006.<ref>{{Cite web|title=David Baltimore {{!}} Division of Biology and Biological Engineering|url=https://www.bbe.caltech.edu/people/david-baltimore|access-date=2021-02-28|website=www.bbe.caltech.edu}}</ref> He founded the [[Whitehead Institute]] and directed it from 1982 to 1990. In 2008, he served as president of the [[American Association for the Advancement of Science]].

At age 37, Baltimore won the Nobel Prize with [[Renato Dulbecco]] and [[Howard Martin Temin|Howard M. Temin]] "for their discoveries concerning the interaction between [[Oncovirus|tumour viruses]] and the genetic material of the cell", specifically the discovery of the enzyme [[reverse transcriptase]].<ref>{{Cite web |title=David Baltimore, The Nobel Prize in Physiology or Medicine 1975 |url=https://www.nobelprize.org/prizes/medicine/1975/baltimore/biographical/ |access-date=2023-09-08 |website=NobelPrize.org |language=en-US}}</ref> He has contributed to [[immunology]], [[virology]], [[cancer research]], [[biotechnology]], and [[recombinant DNA]] research. He has also trained many doctoral students and postdoctoral fellows, several of whom have gone on to notable and distinguished research careers.

==Early life and education==
[[File: David Baltimore NIH.jpg|thumb|right|Baltimore in the 1970s]]
Baltimore was born on March 7, 1938, in [[New York City]] to Gertrude (Lipschitz) and Richard Baltimore.  Raised in the [[Queens]] neighborhoods of [[Forest Hills, Queens|Forest Hills]] and [[Rego Park, Queens|Rego Park]], he moved with his family to suburban [[Great Neck, New York]], while he was in second grade because his mother felt that the city schools were inadequate. His father had been raised as an [[Orthodox Judaism|Orthodox Jew]] and his mother was an [[atheist]], and Baltimore observed Jewish holidays and would attend synagogue with his father through his [[Bar Mitzvah]].<ref name="Lippincott">{{cite web | url = http://oralhistories.library.caltech.edu/168/1/Baltimore,D._OHO.pdf | title = David Baltimore – Interviewed | vauthors = Lippincott S | date = October–November 2009 | publisher = [[California Institute of Technology]] | access-date = February 21, 2013 | quote = But she was also committed to her family and to my father's right to have his religion, and we celebrated the major holidays, we fasted on Yom Kippur, and I walked with my father to the shul, which was a long walk from where we lived. }}</ref> He graduated from [[John L.

Luria and Levinthal invited Baltimore to apply to the [[Massachusetts Institute of Technology]] (MIT).<ref name="Lippincott" /><ref name=":0" /> Baltimore's future promise was evident in his work as a graduate student when he entered MIT's graduate program in biology in 1960 with a brash and brilliant approach to learning science, completing his PhD thesis work in two years.<ref name="Crotty">{{cite book| vauthors = Crotty S |date=2003|title=Ahead of the Curve: David Baltimore's Life in Science|publisher=University of California Press|location=Berkeley, California|isbn=9780520239043}}</ref><ref name="thesis-baltimore-1964">{{cite thesis|url=https://www.proquest.com/docview/302176930/|title=The diversion of macromolecular synthesis in L-cells towards ends dictated by mengovirus.|date=1964|publisher=[[The Rockefeller University]]|type=Ph.D.| vauthors = Baltimore D |id={{ProQuest|302176930 }}|url-access=subscription|oclc=38131761}}</ref> His early interest in phage genetics quickly yielded to a passion for animal viruses.<ref name="Lippincott" /> He took the Cold Spring Harbor course on animal virology in 1961 and he moved to Richard Franklin's (got his doctoral degree from Rockefeller Institute) lab at the Rockefeller Institute at New York City, which was one of the few labs pioneering molecular research on animal virology.<ref name="Lippincott" /> There he made fundamental discoveries on virus replication and its effect on cell metabolism, including the first description of an RNA replicase.

==Career and research==
After his PhD, Baltimore returned to [[Massachusetts Institute of Technology|MIT]] for [[postdoctoral research]] with James Darnell in 1963.<ref name=":1">{{cite journal | vauthors = Baltimore D | title = Sixty Years of Discovery | journal = Annual Review of Immunology | volume = 37 | issue = 1 | pages = 1–17 | date = April 2019 | pmid = 30379594 | doi = 10.1146/annurev-immunol-042718-041210 | doi-access = free }}</ref> He continued his work on virus replication using poliovirus and pursued training in enzymology with [[Jerard Hurwitz]] at [[Albert Einstein College of Medicine]] in 1964/1965.<ref name=":1" />

===Massachusetts Institute of Technology===
==== Reverse transcriptase ====
In 1968, he was recruited once more by soon-to-be Nobel laureate [[Salvador Luria]] to the department of biology at MIT as an associate professor of microbiology.<ref name=LuriaS>{{cite book| vauthors = Luria S |date=1984|title=A slot machine, a broken test tube: an autobiography|publisher=Harper & Row}}</ref> [[Alice S. Huang]] also moved to MIT to continue her research on [[vesicular stomatitis virus]] (VSV). They became a couple, and married in October 1968.<ref name="Huang, Caltech"/> At MIT, Huang, Baltimore, and graduate student Martha Stampfer discovered that VSV replication involved an RNA-dependent RNA polymerase within the virus particle, and used a novel strategy to replicate its RNA genome. VSV entered a host cell as a single negative strand of RNA, but brought with it RNA polymerase to stimulate the processes of transcription and replication of more RNA.<ref name=Bhaskaran/><ref name="Huang, Caltech"/><ref name=EB2015>{{cite web|title=David Baltimore|date=2015|website=Encyclopædia Britannica|url=http://www.britannica.com/EBchecked/topic/51022/David-Baltimore}}</ref>

Baltimore extended this work and examined two RNA tumor viruses, [[Murine leukemia virus|Rauscher murine leukemia virus]] and [[Rous sarcoma virus]].<ref name=Bhaskaran/><ref name="nytimesnobel">{{cite news|title=No Nobel Prize for Whining| vauthors = Judson HF |date=October 20, 2003|url=https://query.nytimes.com/gst/fullpage.html?sec=health&res=9C02E4DE123EF933A15753C1A9659C8B63|newspaper=New York Times}}</ref> He went on to discover [[reverse transcriptase]] (RTase or RT) – the enzyme that polymerizes DNA from an RNA template. In doing so, he discovered a distinct class of viruses, later called [[retrovirus]]es, that use an RNA template to catalyze synthesis of viral DNA.<ref name=Dogma>{{cite web|title=Destroying Dogma: the Discovery of Reverse Transcriptase|url=http://centennial.rucares.org/index.php?page=Destroying_Dogma|website=The Rockefeller University}}</ref> This overturned the simplified version of the central dogma of molecular biology that stated that genetic information flows unidirectionally from DNA to RNA to proteins.<ref name="nytimesnobel"/><ref name=QNA>{{cite journal | vauthors = Baltimore D | title = QnAs with David Baltimore.

The viruses that fall into this category include [[HIV]].<ref name="Huang, Caltech"/><ref name=Dogma/>

The discovery of reverse transcriptase, made contemporaneously with [[Howard Martin Temin|Howard Temin]], who had proposed the provirus hypothesis, showed that genetic information could traffic bidirectionally between DNA and RNA. They published these findings in back-to-back papers in the journal ''Nature''.<ref name=Nature1>{{cite journal | vauthors = Baltimore D | title = RNA-dependent DNA polymerase in virions of RNA tumour viruses | journal = Nature | volume = 226 | issue = 5252 | pages = 1209–11 | date = June 1970 | pmid = 4316300 | doi = 10.1038/2261209a0 | s2cid = 4222378 | bibcode = 1970Natur.226.1209B }}</ref><ref name=Nature2>{{cite journal | vauthors = Temin HM, Mizutani S | title = RNA-dependent DNA polymerase in virions of Rous sarcoma virus | journal = Nature | volume = 226 | issue = 5252 | pages = 1211–3 | date = June 1970 | pmid = 4316301 | doi = 10.1038/2261211a0 | s2cid = 4187764 | bibcode = 1970Natur.226.1211T }}</ref> This discovery made it easier to isolate and reproduce individual genes, and was heralded as evidence that molecular and virological approaches to understanding cancer would yield new cancer treatments.<ref name=":3" /> This may have influenced President Richard Nixon's [[War on Cancer]] which was launched in 1971 and substantially increased research funding for the disease. In 1972, at the age of 34, Baltimore was awarded tenure as a professor of biology at MIT, a post that he held until 1997.

====Asilomar conference on recombinant DNA====
Baltimore also helped [[Paul Berg]] and [[Maxine Singer]] to organize the [[Asilomar Conference on Recombinant DNA]], held in February 1975. The conference discussed possible dangers of new biotechnology, drew up voluntary safety guidelines, and issued a call for an ongoing moratorium on certain types of experiments and review of possible experiments, which has been institutionalized by recombinant DNA advisory committees established at essentially all US academic institutions conducting molecular biology research.<ref name="Lippincott"/> Baltimore was well aware of the importance of the changes occurring in the laboratory: "The whole Asilomar process opened up to the world that modern biology had new powers that you had never conceived of before."<ref name=Crotty/>{{rp|111}}

===MIT Cancer Center===
In 1973, he was awarded an American Cancer Society Professor of Microbiology that provided substantial salary support. Also in 1973, he became one of the early faculty members in the newly organized [[David H. Koch Institute for Integrative Cancer Research|MIT Center for Cancer Research]] (CCR), capping a creative and industrious period of his career with nearly fifty research publications including the paradigm-shifting paper on reverse transcriptase.<ref>{{Cite web|title=The Koch Institute: Video – Building the Foundation of Modern Cancer Research: Four Decades of Discovery within the CCR at MIT|url=https://ki.mit.edu/approach/ki/history/ccr|access-date=2021-02-28|website=ki.mit.edu}}</ref> The MIT CCR was led by Salvador E. Luria and quickly achieved pre-eminence with a group of faculty including Baltimore, [[Phillips Robbins]], [[Herman Eisen]], [[Phillip Allen Sharp|Philip Sharp]], and [[Robert Weinberg (biologist)|Robert Weinberg]], who all went on to illustrious research careers.<ref name=LuriaS/> Baltimore was honored as a Fellow of the [[American Academy of Arts and Sciences]] in 1974.<ref name=NobelBio/> He returned to New York City in 1975, for a year-long sabbatical at Rockefeller University working with Jim Darnell.<ref name=":2" />

=== Nobel Prize ===
In 1975, at the age of 37, he shared the Nobel Prize for [[Nobel Prize in Physiology or Medicine|Physiology or Medicine]] with [[Howard Martin Temin|Howard Temin]] and [[Renato Dulbecco]].<ref name=":2" /> The citation reads, "for their discoveries concerning the interaction between tumor viruses and the genetic material of the cell."<ref name="NobelPrize1975">{{cite press release|date=October 1975|title=Physiology or Medicine 1975 – Press Release|url=https://www.nobelprize.org/nobel_prizes/medicine/laureates/1975/press.html|access-date=November 6, 2015}}</ref> At the time, Baltimore's greatest contribution to virology was his discovery of [[reverse transcriptase]] (Rtase or RT) which is essential for the reproduction of [[retrovirus]]es such as [[HIV]] and was discovered independently, and at about the same time, by Satoshi Mizutani and Temin.<ref name="OralHistoryCHF" />

After winning the Nobel Prize, Baltimore reorganized his laboratory, refocusing on immunology and virology, with [[immunoglobulin]] gene expression as a major area of interest. He tackled new problems such as the pathogenesis of [[Abelson murine leukemia virus]] (AMuLV), lymphocyte differentiation and related topic in immunology. In 1980, his group isolated the oncogene in AMuLV and showed it was a member of a new class of protein kinases that used the amino acid tyrosine as a phosphoacceptor.<ref name="Witte">{{cite journal | vauthors = Witte ON, Dasgupta A, Baltimore D | title = Abelson murine leukaemia virus protein is phosphorylated in vitro to form phosphotyrosine | journal = Nature | volume = 283 | issue = 5750 | pages = 826–31 | date = February 1980 | pmid = 6244493 | doi = 10.1038/283826a0 | s2cid = 4239008 | bibcode = 1980Natur.283..826W }}</ref> This type of enzymatic activity was also discovered by [[Anthony R. Hunter|Tony Hunter]], who has done extensive work in the area. He also continued to pursue fundamental questions in RNA viruses and in 1981, Baltimore and [[Vincent Racaniello]], a post-doctoral fellow in his laboratory, used [[recombinant DNA]] technology to generate a [[plasmid]] encoding the genome of [[poliovirus]], an animal RNA virus.<ref name="NobelLecture" /> The plasmid DNA was introduced into cultured mammalian cells and infectious poliovirus was produced. The infectious clone, DNA encoding the genome of a virus, is a standard tool used today in virology.

===Whitehead Institute for Biomedical Research===
In 1982, with a charitable donation by businessman and philanthropist Edwin C. "Jack" Whitehead, Baltimore was asked to help establish a self-governed research institute dedicated to basic biomedical research.<ref name=WI1>{{cite web|title=Whitehead Institute Introduction|url=http://www.wi.mit.edu/about/history}}</ref> Baltimore persuaded Whitehead that MIT would be the ideal home for the new institute, convinced that it would be superior at hiring the best researchers in biology at the time, thus ensuring quality.<ref name=":0" /> Persuading MIT faculty to support the idea was far more difficult. MIT as an institution had never housed another before, and concerns were raised that the wealth of the institute might skew the biology department in directions faculty did not wish to take, and that Baltimore himself would gain undue influence over hiring within the department.<ref name=":0" /><ref name=":1" /><ref>{{Cite news| vauthors = Teltsch K |date=1992-02-04|title=Edwin C. Whitehead, 72, Dies; Financed Biomedical Research|language=en-US|work=The New York Times|url=https://www.nytimes.com/1992/02/04/nyregion/edwin-c-whitehead-72-dies-financed-biomedical-research.html|access-date=2021-04-14|issn=0362-4331}}</ref> The controversy was made worse by an article published by the Boston Globe framing the institute as corporate takeover of MIT.<ref name=":0" /><ref name=":1" /> After a year of intensive discussions and planning, faculty finally voted in favor of the institute.<ref name=":0" /> Whitehead, Baltimore, and the rest of the planning team devised a unique structure of an independent research institute composed of "members" with a close relationship with the department of biology of MIT. This structure continues to this day to attract an elite interactive group of faculty to the Department of Biology at MIT and has served as a model for other distinguished institutes such as the [[Broad Institute]].

[[Whitehead Institute|The Whitehead Institute for Biomedical Research]] (WIBR) was launched with $35 million to construct and equip a new building located across the street from the MIT cancer center at 9 Cambridge Center in Cambridge Massachusetts. The institute also received $5 million per year in guaranteed income and a substantial endowment in his will (for a total gift of $135 million). Under Baltimore's leadership, a distinguished group of founding members including [[Gerald Fink]], [[Rudolf Jaenisch]], [[Harvey Lodish]], and [[Robert Weinberg (biologist)|Robert Weinberg]] was assembled and eventually grew to 20 members in disciplines ranging from immunology, genetics, and oncology to fundamental developmental studies in mice and fruit flies.<ref name="WI2">{{cite web|title=Whitehead Institute Founding Faculty|url=http://www.wi.mit.edu/about/history/founders}}</ref> Whitehead Institute's contributions to bioscience have long been consistently outstanding. Less than a decade after its founding with continued leadership by Baltimore, the Whitehead Institute was named the top research institution in the world in molecular biology and genetics, and over a recent 10-year period, papers published by Whitehead scientists, including many from Baltimore's own lab, were the most cited papers of any biological research institute. The Whitehead Institute was an important partner in the [[Human Genome Project]].<ref name="genome">{{cite web| vauthors = Kumar S |date=July 12, 2000|title=Whitehead scientists enjoy genome sequence milestone|url=http://web.mit.edu/newsoffice/2000/whitehead-0712.html|publisher=Whitehead Institute}}</ref>

Baltimore served as director of the WIBR and expanded the faculty and research areas into key areas of research including mouse and drosophila genetics. During this time, Baltimore's own research program thrived in the new Institute. Important breakthroughs from Baltimore's lab include the discovery of the key transcription factor [[NF-κB]] by Dr. Ranjan Sen and David Baltimore in 1986.<ref name="pmid3091258">{{cite journal | vauthors = Sen R, Baltimore D | title = Multiple nuclear factors interact with the immunoglobulin enhancer sequences | journal = Cell | volume = 46 | issue = 5 | pages = 705–16 | date = August 1986 | pmid = 3091258 | doi = 10.1016/0092-8674(86)90346-6 | s2cid = 37832531 }}</ref> This was part of a broader investigation to identify nuclear factors required for lg gene expression in B lymphocytes. However, NF-κB turned out to have much broader importance in both innate and adaptive immunity and viral regulation. NF-κB is involved in regulating cellular responses and belongs to the category of "rapid-acting" primary transcription factors.

As early as 1984, Rudolf Grosschedl and David Weaver, postdoctoral fellows, in Baltimore's laboratory, were experimenting with the creation of [[Genetically modified mouse|transgenic mice]] as a model for the study of disease.

In 1990, as a student in David Baltimore's laboratory at MIT, [[George Q. Daley]] demonstrated that a fusion protein called bcr-abl is sufficient to stimulate cell growth and cause chronic myelogenous leukemia (CML). This work helped to identify a class of proteins that become hyperactive in specific types of cancer cells. It helped to lay the groundwork for a new type of drug, attacking cancer at the genetic level: [[Brian Druker]]'s development of the anti-cancer drug [[Imatinib]] (Gleevec), which deactivates bcr-abl proteins. Gleevec has shown impressive results in treating [[chronic myelogenous leukemia]] and also promise in treating [[gastrointestinal stromal tumor]] (GIST).<ref name=Nathan>{{cite news| vauthors = Nathan DG |title=The Relevant Biomedical Research|url=http://harvardmagazine.com/2007/01/the-relevant-biomedical.html|access-date=May 25, 2015|work=Harvard Magazine|issue=January–February|date=2007}}</ref><ref name=Gleevec2001>{{cite news| vauthors = Wade N |title=Swift Approval For a New Kind Of Cancer Drug|url=https://www.nytimes.com/2001/05/11/us/swift-approval-for-a-new-kind-of-cancer-drug.html|access-date=May 25, 2015|work=The New York Times|date=May 11, 2001}}</ref><ref name=AMACON>{{cite book| vauthors = Smith G |title=The genomics age: how DNA technology is transforming the way we live and who we are|date=2005|publisher=AMACOM|location=New York|isbn=978-0814408438|page=[https://archive.org/details/genomicsagehowdn0000smit/page/140 140]|url=https://archive.org/details/genomicsagehowdn0000smit|url-access=registration|access-date=May 25, 2015}}</ref>

===Rockefeller University===
Baltimore served as the director of the Whitehead Institute until July 1, 1990, when he was appointed the sixth president of Rockefeller University in New York City. He moved his research group to New York in stages and continued to make creative contributions to virology and cellular regulation.<ref name=":0" /> He also began important reforms in fiscal and faculty management and promoted the status of junior faculty at the university.<ref>{{cite journal | vauthors = Hall SS | title = Baltimore resigns at Rockefeller | journal = Science | volume = 254 | issue = 5037 | pages = 1447 | date = December 1991 | pmid = 1962199 | doi = 10.1126/science.1962199 | bibcode = 1991Sci...254.1447H }}</ref> After resigning on December 3, 1991 (see Imanishi-Kari case), Baltimore remained on the Rockefeller University faculty and continued research until the spring of 1994.

During Baltimore's tenure at Caltech, United States President [[Bill Clinton]] awarded Baltimore the [[National Medal of Science]] in 1999 for his numerous contributions to the scientific world. In 2004, Rockefeller University gave Baltimore its highest honor, Doctor of Science (''honoris causa'').<ref>{{cite journal | vauthors = Bhattacharjee Y |s2cid=172731927 |title=The Balance of Justice |journal=Science |volume=304 |issue=5679 |page=1901 |date=June 25, 2004 |doi=10.1126/science.304.5679.1901a}}</ref>

=== Caltech Laboratory (1997–2019) ===
Baltimore's laboratory at Caltech focused on two major research areas: understanding the development and functioning of the mammalian immune system and translational studies creating viral vectors to make the immune system more effective in resisting cancer. Their basic studies went in two directions: understanding the diverse activity of the NF-κB transcription factor, and understanding the normal and pathologic functions of microRNA.

==== Translational Science Initiatives ====
A primary focus of Baltimore's lab was use of gene therapy methods to treat HIV and cancer.<ref name=":5">{{Cite web|date=2010-05-21|title=David Baltimore|url=https://www.broadinstitute.org/bios/david-baltimore|access-date=2021-04-14|website=Broad Institute|language=en}}</ref> In the early 2000s one of Baltimore's graduate students, Lili Yang, developed a [[lentivirus]] vector that allowed for the cloning of genes for two chains of TCR. Recognizing its potentially profound implications for enhancing immunity, Baltimore developed a translational research initiative within his laboratory called "Engineering Immunity." The Bill and Melinda Gates Foundation awarded the program with a Grand Challenge Grant, and he used the funding to divide the initiative into four research programs and hire additional lab staff to lead each one. Two of the research programs sparked gene therapy start-up companies, Calimmune and Immune Design Corp, founded in 2006 and 2008 respectively.<ref>{{Cite web|title=Calimmune, Inc.|date=June 27, 2015 |url=https://www.linkedin.com/company/calimmune-inc}}</ref><ref>{{Cite web|title=Immune Design Corp – Company Profile and News|url=https://www.bloomberg.com/profile/company/IMDZ:US|access-date=2021-04-14|website=Bloomberg.com|language=en}}</ref> A third program focused on the development of an HIV vaccine, and eventually lead to clinical trials at NIH.<ref name=":1" /> In 2009 Baltimore became director of the Joint Center for Translational Medicine, a shared initiative between Caltech and UCLA aimed at developing bench to bedside medicine.<ref name=":5" />

==== MicroRNA Research ====
A focus of Baltimore's lab from his arrival at Caltech to the lab's closure in 2018 was understanding the role of [[microRNA]] in the immune system.<ref name=":1" /> MicroRNAs provide fine control over gene expression by regulating the amount of protein made by particular messenger RNAs.<ref name="CaltechBio">{{cite web|title=David Baltimore|url=https://www.bbe.caltech.edu/content/david-baltimore|website=Division of Biology and Biological Engineering|publisher=Caltech|access-date=May 25, 2015|archive-url=https://web.archive.org/web/20160601234446/http://www.bbe.caltech.edu/content/david-baltimore|archive-date=June 1, 2016|url-status=dead}}</ref>
In recent research led by [[Jimmy Zhao]], Baltimore's team has discovered a small RNA molecule called microRNA-146a (miR-146a) and bred a strain of mice that lacks miR146a.  They have used the miR146a(-) mice as a model to study the effects of chronic inflammation on the activity of hematopoietic stem cells (HSCs).  Their results suggest that microRNA-146a protects HSCs during chronic inflammation, and that its lack may contribute to blood cancers and bone marrow failure.<ref name="Dish2013">{{cite news|title=RNA Molecule Protects Stem Cells During Inflammation|url=https://beyondthedish.wordpress.com/2013/06/11/rna-molecule-protects-stem-cells-during-inflammation/|access-date=May 25, 2015|work=Beyond the Dish|date=June 11, 2013}}</ref>

===== Splicing Control Research =====
Another concentration within Baltimore's lab in recent years was control of inflammatory and immune responses, specifically splicing control of gene expression after inflammatory stimuli.<ref name=":5" /> In 2013 they discovered that ordered expression of genes following an inflammatory stimulus was controlled by splicing, not transcription as previously supposed.<ref>{{cite journal | vauthors = Hao S, Baltimore D | title = RNA splicing regulates the temporal order of TNF-induced gene expression | journal = Proceedings of the National Academy of Sciences of the United States of America | volume = 110 | issue = 29 | pages = 11934–9 | date = July 2013 | pmid = 23812748 | doi = 10.1073/pnas.1309990110 | pmc = 3718113 | bibcode = 2013PNAS..11011934H | doi-access = free }}</ref> This led to further discoveries that delayed splicing was caused by introns, with the revelation that RNA-binding protein BUD13 acts at this intron to increase the amount of successful splicing (2 articles by Luke Frankiw published in 2019 and 2020).<ref>{{cite journal | vauthors = Frankiw L, Majumdar D, Burns C, Vlach L, Moradian A, Sweredoski MJ, Baltimore D | title = BUD13 Promotes a Type I Interferon Response by Countering Intron Retention in Irf7 | language = English | journal = Molecular Cell | volume = 73 | issue = 4 | pages = 803–814.e6 | date = February 2019 | pmid = 30639243 | doi = 10.1016/j.molcel.2018.11.038 | doi-access = free }}</ref><ref>{{cite journal | vauthors = Frankiw L, Mann M, Li G, Joglekar A, Baltimore D | title = Alternative splicing coupled with transcript degradation modulates OAS1g antiviral activity | journal = RNA | volume = 26 | issue = 2 | pages = 126–136 | date = February 2020 | pmid = 31740586 | pmc = 6961538 | doi = 10.1261/rna.073825.119 }}</ref>

In an autobiographical piece published in Annual Review Immunology in 2019, Baltimore announced that half of his lab space at Caltech would be taken over by a new assistant professor in Fall 2018, and his current lab group would be the last. "I have been involved in research for 60 years, and I think it is time to leave the field to younger people."<ref name=":1" />

===Public policy===
In the span of his career, Baltimore has profoundly impacted national science policy debates, including the AIDS epidemic and recombinant DNA research.<ref name=":5" /><ref name=":6" /> His efforts to organize the Asilomar Conference on Recombinant DNA were key to creating consensus within scientific and policy spheres.

In recent years Baltimore has joined with other scientists to call for a worldwide moratorium on use of a new genome-editing technique to alter inheritable human DNA.<ref name="NYTimes2015" /> A key step enabling researchers to slice up any DNA sequence they choose was developed by Emmanuelle Charpentier, then at Umea University in Sweden, and [[Jennifer Doudna|Jennifer A.

==Controversies==
=== Imanishi-Kari case ===
{{Main|Thereza Imanishi-Kari}}

During the late 1980s and early 1990s, Thereza Imanishi-Kari, a scientist who was not in Baltimore's laboratory but in a separate, independent laboratory at MIT, was implicated in a case of [[scientific fraud]].  The case received extensive news coverage and a Congressional investigation. The case was linked to Baltimore's name because of his scientific collaboration with and later his strong defense of Imanishi-Kari against accusations of fraud.

In 1986, while a professor of biology at MIT and director at Whitehead, Baltimore co-authored a scientific paper on [[immunology]] with Thereza Imanishi-Kari (an assistant professor of biology who had her own laboratory at MIT) as well as four others.<ref>{{cite journal | vauthors = Weaver D, Reis MH, Albanese C, Costantini F, Baltimore D, Imanishi-Kari T | title = Altered repertoire of endogenous immunoglobulin gene expression in transgenic mice containing a rearranged mu heavy chain gene | journal = Cell | volume = 45 | issue = 2 | pages = 247–59 | date = April 1986 | pmid = 3084104 | doi = 10.1016/0092-8674(86)90389-2 | s2cid = 26659281 }}{{Retracted|doi=10.1016/0092-8674(91)90085-D|pmid=2032282|intentional=yes}}</ref> A postdoctoral fellow in Imanishi-Kari's laboratory, Margot O'Toole, who was not an author, reported concerns about the paper, ultimately accusing Imanishi-Kari of fabricating data in a cover-up. Baltimore, however, refused to retract the paper.

O'Toole soon dropped her challenge, but the [[NIH]], which had funded the contested paper's research, began investigating, at the insistence of [[Walter W. Stewart (scientist)|Walter W. Stewart]], a self-appointed fraud buster, and Ned Feder, his lab head at the NIH.<ref name=weiss /> [[United States Congress|Representative]] [[John Dingell]] (D-MI) also aggressively pursued it, eventually calling in [[U.S. Secret Service]] (USSS; [[U.S. Treasury]]) document examiners.<ref>"Fraud in NIH Grant Programs," April 12, 1988; "Scientific Fraud," May 4 & 9, 1989; and "Scientific Fraud (Part 2)," May 14, 1990 (transcript includes April 30, 1990 hearing on [[Robert Gallo|R. Gallo]]'s NIH lab)</ref>

Around October 1989, when Baltimore was appointed president of Rockefeller University, around a third of the faculty opposed his appointment because of concerns about his behaviour in the Imanishi-Kari case. He visited every laboratory, one by one, to hear those concerns directly from each group of researchers.<ref name=weiss>{{citation |title= Conduct Unbecoming? | vauthors = Weiss P |date= October 29, 1989 |work= New York Times |pages= 40–41, 68–69, 95 |url= https://www.nytimes.com/1989/10/29/magazine/conduct-unbecoming.html?pagewanted=all&src=pm |pmid= 11650263 }}</ref>

In a draft report dated March 14, 1991, based mainly on USSS forensics findings, NIH's fraud unit, then called the Office of Scientific Integrity (OSI), accused Imanishi-Kari of falsifying and fabricating data. It also criticized Baltimore for failing to embrace O'Toole's challenge.{{Citation needed|date=September 2008}} Less than a week later, the report was leaked to the press.<ref>{{cite web | vauthors = Hilts PJ | date = March 21, 1991 | url = https://www.nytimes.com/books/98/09/20/specials/baltimore-data.html | title = Crucial Data Were Fabricated In Report Signed by Top Biologist | work = [[The New York Times]] }}</ref> Baltimore and three co-authors then retracted the paper; however, Imanishi-Kari and Moema H.

In July 1992, the US Attorney for the District of Maryland, who had been investigating the case, announced he would not bring criminal or civil charges against Imanishi-Kari.<ref>Gladwell, Malcolm (July 14, 1992) "Prosecutors Halt Scientific Fraud Probe; Researcher Baltimore Claims Vindication, Plans to 'Unretract' Paper".

An HHS appeals panel began meeting in June 1995 to review all charges in detail. In June 1996, the panel ruled that the ORI had failed to prove any of its 19 charges. After throwing out much of the documentary evidence gathered by the ORI, the panel dismissed all charges against Imanishi-Kari. As their final report stated, the HHS panel "found that much of what ORI presented was irrelevant, had limited probative value, was internally inconsistent, lacked reliability or foundation, was not credible or not corroborated, or was based on unwarranted assumptions."  It did conclude that "The Cell paper as a whole is rife with errors of all sorts ... [including] some which, despite all these years and layers of review, have never previously been pointed out or corrected. Responsibility ... must be shared by all participants." Neither OSI nor ORI ever accused Baltimore of research misconduct.<ref name=HHS1996>{{cite web|title=Thereza Imanishi-Kari, Ph.D., DAB No. 1582 (1996) Department of Health and Human Services Departmental Appeals Board Research Integrity Adjudications Panel Subject: Thereza Imanishi-Kari, Ph.D. Docket No. A-95-33 Decision No. 1582|url=https://www.hhs.gov/dab/decisions/dab1582.html|website=HHS.gov|publisher=Department of Health and Human Services|date=June 21, 1996|quote=HHS report exonerating Imanishi-Kari.}}</ref><ref name=gateway>{{cite news |title=The fortune that never was | vauthors = Warsh D | quote=The public skirmish over the reputations of Massachusetts Institute of Technology professor David Baltimore and Tufts University researcher Thereza Imanishi-Kari has been formally ended by a report deeply embarrassing to the government |url=http://www.gatewaycoalition.org/files/Gateway_Project_Moshe_Kam/Resource/DBCre/bosg30jun96.html |newspaper=Boston Globe |date=June 30, 1996 }}</ref> The reputations of Stewart and Feder, who had pushed for the investigation, were badly damaged.<ref name=gateway /> The pair were reassigned to other positions at NIH because they failed to maintain productivity in their roles as scientists and questions were raised about the legitimacy of their self-appointed inquiries into scientific integrity.<ref>{{Cite news| vauthors = Hilts PJ |date=1993-06-13|title=Inspector Ends A Hunger Strike Against Agency|language=en-US|work=The New York Times|url=https://www.nytimes.com/1993/06/13/us/inspector-ends-a-hunger-strike-against-agency.html|access-date=2021-04-14|issn=0362-4331}}</ref>

=== COVID-19 and lab-leak theory ===
In May 2021, Baltimore was quoted in the ''[[Bulletin of the Atomic Scientists]]'' in an article about the origins of the [[COVID-19]] virus, saying, "When I first saw the furin cleavage site in the viral sequence, with its arginine codons, I said to my wife it was the smoking gun for the origin of the virus. These features make a powerful challenge to the idea of a natural origin for SARS2."<ref>{{Cite news|last=Wade|first=Nicholas|date=May 5, 2021|title=The origin of COVID: Did people or nature open Pandora's box at Wuhan?|work=Bulletin of the Atomic Scientists|url=https://thebulletin.org/2021/05/the-origin-of-covid-did-people-or-nature-open-pandoras-box-at-wuhan/|access-date=June 10, 2021}}</ref> This quote was widely shared and gave credence to the possibility of a [[COVID-19 lab leak theory|Wuhan lab leak]] that has been discussed extensively as part of [[investigations into the origin of COVID-19]].

A month later, Baltimore told the ''[[Los Angeles Times]]'' that he "should have softened the phrase 'smoking gun' because I don't believe that it proves the origin of the furin cleavage site but it does sound that way. I believe that the question of whether the sequence was put in naturally or by molecular manipulation is very hard to determine but I wouldn't rule out either origin."<ref>{{Cite news|last=Hiltzik|first=Michael|date=June 8, 2021|title=A Nobel laureate backs off from claiming a 'smoking gun' for the COVID-19 lab-leak theory|work=[[Los Angeles Times]]|url=https://www.latimes.com/business/story/2021-06-08/nobel-laureate-baltimore-smoking-gun-for-the-covid-lab-leak-theory|access-date=June 10, 2021}}</ref>
