How Did the 'Berlin Patient' Rid Himself of HIV?

sciencehabit writes: Researchers are closer to unraveling the mystery of how Timothy Ray Brown, the only human cured of HIV, defeated the virus, according to a new study. Although the work doesn't provide a definitive answer, it rules out one possible explanation. [R]esearchers point to three different factors that could independently or in combination have rid Brown’s body of HIV. The first is the process of conditioning, in which doctors destroyed Brown’s own immune system with chemotherapy and whole body irradiation to prepare him for his bone marrow transplant. His oncologist, Gero Hütter, who was then with the Free University of Berlin, also took an extra step that he thought might not only cure the leukemia but also help rid Brown’s body of HIV. He found a bone marrow donor who had a rare mutation in a gene that cripples a key receptor on white blood cells the virus uses to establish an infection. (For years, researchers referred to Brown as "the Berlin patient.") The third possibility is his new immune system attacked remnants of his old one that held HIV-infected cells, a process known as graft versus host disease.

      IMO he probably still has traces of the virus within his body somewhere, but in such small quantities that it's undetectable. Other viruses are known to do this, such as chickenpox, which can resurface later in the form of shingles if the immune system ever weakens. Except HIV feeds off of the immune system itself, so it's likely he'll never see symptoms of it again.

      However it would be unwise for him to do whatever he did to contract it in the first place as he could either spread his to somebody else or contract another variation of the disease that doesn't rely on the same receptor that he is now immune to (and yes, he does fit the "risk category" demographic if you haven't read his history.)

    Although the work doesn't provide a definitive answer, it rules out one possible explanation. [R]esearchers point to three different factors that could independently or in combination have rid Brown’s body of HIV.

    Unfortunately the summary forgets to mention the explanation that was ruled out or even clearly delineate the three different factors (though the latter was more the fault of the original article).

    From my reading of TFA:

    Explanation 1: Conditioning: The radiation that destroyed his immune system also killed off the HIV (because HIV lives in the cells of the immune system).

    Explanation 2: Shiny new immune system: The new bone marrow had a mutation that was immune to HIV and that cured him (maybe by detecting and killing HIV infected cells?).

    Explanation 3: Graft vs host: The new immune system killed off his old one, not just the HIV infected cells but all the old immune systems cells including those infected with HIV.

    So the researchers took chimps, extracted some stem cells (bone marrow?), infected them with SHIV (Simian HIV), destroyed their immune systems with radiation, then reinjected the uninfected stem cells.

    So they tried supplementing with just selenium and that helped but did not reverse the disease.

    So they looked at what other essential (the body can't make them) molecules it took from the body and ignored non-essential (the body can make more of those molecules and doesn't have to ingest them) molecules the virus stripped from the host cells.

    Low and behold, Tryptophan, Cysteine and Glutamine.

    If you look up what has glutamine an in what amounts, nothing come close to beef[1] and it also has a fair amount of Tryptophan.

    Cysteine is in cheese, the more aged the better. Parrnasian probabky has more than more other common ones I'd guess.

They have so much selenium, that if you eat a handful a day you'll have selenosis in a week - a, um, disruption in the alimentary canal shall we say.

    From both ends. But they're utterly essential for heart, brain and immune system.

    In fact if you look you'll notice Senegal, like Brazil, has natural deposits of selenium in the soil everywhere and it was this that accounted for the reduced rate of incidence of HIV in Senegal - the HIV rate there is as low as it is in the US despite the fact the Senegalese have the same sub saharan cultural practices (and by that I mean fucking a lot) as the rest of the Sub Saharan Africa that has a 5-10X higher rate of HIV infection . This stands out, as does Finland where they put a lot of selenium in the soil to try to slow down heart diseases - the aids rate is lower than normal there too.

    So "eating a lot of protein" per se won't do it. You'd have to use beef, cheese and a brazil nut or two.
