talked at UC Davis a few days ago. I met with him in the afternoon before his talk. It was one of the more interesting discussions I have had in a long time. He has done some very
(e.g., comparative genomics, HIV, feline evolution) though most of what we talked about was not work per se (e.g., we talked a lot about baseball and big cats since my kids are obsessed with big cats).
Anyway, below is a "Storification" of tweets from his talk. Best part - he signed a copy of his

Can't wait for talk at 4 PM today at #UCDavis Genome Ctr by Stephen O'Brien on "Three Decades of Genomics and AIDS" http://pic.twitter.com/dQG4tBsoJonathan Eisen
@phylogenomics Wow! Interesting topic. Wish I was attending.Setor Amuzu
As an evolutionary biologist am jealous of name of Obrien's "Theodosius Dobzhansky Center for Genome Bioinformatics" http://shar.es/4vIBYJonathan Eisen
@phylogenomics any podcasts available?Cuquis R
SJ Obrien - head of new Dobzhansky Inst - intro by Harris Lewin, discussing how Dobzhansky finished his career here at #UCDavis:Jonathan Eisen
Lewin point out that Steven O Brien has been called the Indiana Jones of Genomes (e.g.., http://www.genomenewsnetwork.org/articles/2004/03/19/tears.php ) #ucdavisJonathan Eisen
Lewin: Steven O' Brien is also one of the coordinators of the genome 10K project http://genome10k.soe.ucsc.edu/participants #UCDavisJonathan Eisen
Steven O Brien launching into his talk at #ucdavis http://pic.twitter.com/RTadoUJmJonathan Eisen
O'Brien at #UCDavis: Giving props to T. Dobzhansky and his pioneering work on population geneticsJonathan Eisen
O'Brien at #UCDavis: discussing how population genetics help lead to many whole fields/areas incl. conservation genetics, DNA forensics, etcJonathan Eisen
Stephen J. O'Brien: is on Plagues and people Contagion Genomics & Beyond. 3 areas: Gene Discovery, Conservation Genetics, DNA forensicsDawei Lin
O'Brien at #UCDavis: began work on AIDS epidemic partly as model for way to connect human genetics and infectious diseaseJonathan Eisen
O'Brien at #UCDavis: close to 30 million people have died of AIDS and close to 30 million more are infected w/ HIV & disease still spreadingJonathan Eisen
@Curosik don't think soJonathan Eisen
O'Brien at #UCDavis: heterogeneity in progression in HIV led him to try to use advances in human genetics to look for AIDS restrictive genesJonathan Eisen
SJO: Oct. 1996 AIDS quilt is a symbol of the pandemic disease with 40K Tabard Emblems on that day at the Capitol Hill.Dawei Lin
O'Brien at #UCDavis: early in AIDS epidemic got access to samples from different groups of people to test role of human genes in progressionJonathan Eisen
O'Brien at #UCDavis: looked for genetic variation in AIDS resistance, progression rate, outcomes, response to HAART therapyJonathan Eisen
O'Brien at #UCDavis: in 1996 5 groups discovered that CCR5 (a G coupled seven transmembrane receptor) was target of HIV for cell entryJonathan Eisen
O'Brien at #UCDavis: looked for CCR5 mutations in cohorts of patients w/ HIV & found that homozygous mutations were protectiveJonathan Eisen
SJO: CCR5 is the binding target for HIV. People with CCR5 delta with a 32 peptide deletions do not have HIV infections.Dawei Lin
O'Brien at #UCDavis: those people heterozygous for CCR5 deletions showed slower progression of HIV infectionJonathan Eisen
@phylogenomics would love to see the stats methods on thatLewis Lab
@Lewis_Lab seems to be relatively old data ...Jonathan Eisen
Obrien at #UCDavis: many scientists occasionally like to do more than publish in a good journal, some would like to translate to bedsideJonathan Eisen
SJO: People study genes about infectious diseases should not stop at publishing on a good journal, should bring it to the bedside.Dawei Lin
Obrien at #UCDavis: re: delta32 mutation in CCR5 and modifies Dobzhansky "nothing in medicine makes sense except in light of evolution"Jonathan Eisen
Obrien at #UCDavis: discussing how frequency of CCR5 delta32 mutation has increased rapidly over time; suggest this is due to ++ selectionJonathan Eisen
@phylogenomics I'm not seeing any open access/open data reports.Lewis Lab
Obrien at #UCDavis: 20 mutations in CCR5 have been found outside of delta32 mutation; 18/20 are amino acid changing; suggests ++ selectionJonathan Eisen
SJO: 1/5 people now is CCR5 delta 32 carriers. There are 22 variants. 18 of them changes peptides.Dawei Lin
@Lewis_Lab http://dobzhanskycenter.bio.spbu.ru/pdf/sjop/MS379_Martin.pdf ???Jonathan Eisen
Obrien at #UCDavis: Suggests something influenced CCR5 mutations prior to AIDS epidemic (admits much of his theories on this controversial)Jonathan Eisen
OBrien at #UCDavis now reading from Tears of the Cheetah http://www.amazon.com/Tears-Cheetah-Genetic-Secrets-Ancestors/dp/0312339003 his book on genetics / genomicsJonathan Eisen
@Lewis_Lab maybe from this ??? http://journals.lww.com/jaids/Fulltext/1998/12010/Distinctive_Effects_of_CCR5,_CCR2,_and_SDF1.9.aspxJonathan Eisen
O'Brien at #UCDavis: suggests that bubonic plague may have influenced CCCR5 mutation frequencies over timeJonathan Eisen
O'Brien at #UCDavis: discussing plague epidemic in 1665 and 1666 (reading from his book)Jonathan Eisen
@phylogenomics that got me the statistical test I was looking for--thanks. I don't find the article very intuitive, thoughLewis Lab
O'Brien at #UCDavis: discussing their estimates of the age of the CCR5 delta 32 mutations by looking at the size of the linkage groupJonathan Eisen
O'Brien at #UCDavis: estimates of the date of the origin of the spread of the CCR5 delta 32 mutation is correlated w/ plague epidemicJonathan Eisen
O'Brien at #UCDavis: many many waves of plague epidemics over time (though he notes many other possible epidemics also at same general time)Jonathan Eisen
@phylogenomics thanks. This is a good case study for the stats class.Lewis Lab
"@phylogenomics O'Brien suggests that bubonic plague may have influenced CCCR5 mutation frequencies" No doubt a 1-2 insC mutation.Donald Atkinson
SJO: Conspiracy theories of black death cause CCR5 mutation hike, which mostly found in Caucasians.Dawei Lin
O'Brien at #UCDavis: refs a 2004 Nature study of mice w/ CCR5 delta 32 homozygous mutation; -/- have 90+% reduction in Y.pestis uptakeJonathan Eisen
O'Brien at #UCDavis: after 9/11 & anthrax attack collaborated w/ people to look at smallpox infection in CCR5 delta 32 mutant cellJonathan Eisen
"The O'Brien at #UCDavis" stream of tweets by @phylogenomics is fascinating. Must-read for biology folks.Rob Quarles
@phylogenomics What is his book? I show the PBS vid he was in few years ago to my molec epi class each year to discuss CCR5/plague/HIVTara C. Smith
O'Brien at #UCDavis: many other viruses have been screened for whether they make use of CCR5Jonathan Eisen
@phylogenomics thanks for tweets re O'Brien lecture. Say hi to Steve for me!Kathy Belov
@aetiology Tears of a Cheetah http://www.amazon.com/Tears-Cheetah-Genetic-Secrets-Ancestors/dp/0312339003Jonathan Eisen
Obrien at #UCDavis: delta 32 mutations in CCR5 may lead to higher risk to West Nile virus ...Jonathan Eisen
SJO: people with homozygous CCR5 delta mutations are susceptible to West Nile virus, not HIV.Dawei Lin
Obrien at #UCDavis: looking back to 1996 b/c this is when HAART therapy for HIV was startedJonathan Eisen
Obrien at #UCDavis: showing slide from Tony Fauci of FDA Approved antiretroviral drugs; now many new drugs going after CCR5 interactionJonathan Eisen

Obrien at #UCDavis: here is the WSJ news story about The Berlin Patient http://online.wsj.com/article/SB122602394113507555.htmlJonathan Eisen
Obrien at #UCDavis: says the story of the Berlin patient is an anecdote; emphasizes it is one patient; need more information / data / casesJonathan Eisen
Obrien at #UCDavis: refs SciAm article http://www.scientificamerican.com/article.cfm?id=blocking-hivs-attack where gene therapy for HIV patients reported; he's skeptical about peer reviewJonathan Eisen

Comment at Obrien talk at #UCDavis: says to students in crowd that you have heard a talk about thinking which most people don't do anymoreJonathan Eisen
@phylogenomics Nice. He definitely saw importance of donor appreciation/respect differently than most in the early days.Rebecca Skloot
@phylogenomics I wanna know what happened to his amazing frozen zoo at NCI! Hope he took it w/him; he worried re who would take care of itRebecca Skloot
@RebeccaSkloot he did not discuss this ...Jonathan Eisen
Love @phylogenomics tweets on O'Brien's talk at #UCDavis. Everything he said on CCR5/HIV/Berlin pt is right up my alley.Nathalia Holt
My kids are very happy w/ autographed copy of "Tears of the Cheetah" Steven O Brien gave me after his talk at #ucdavis http://pic.twitter.com/SCEh5AXkJonathan Eisen
As follow up to post about "Tears of a cheetah" - my kids are a bit obsessed w/ big cats ... http://pic.twitter.com/M82V4fiHJonathan Eisen
@phylogenomics How do the cats get along with all the microbes?Cindy Manson
@CynthiaManson1 extremely well http://pic.twitter.com/joOoehUWJonathan Eisen
