"Top AIDS scientists are scratching their heads about new data from the most famous HIV patient in the world — at least to people in the AIDS community."

"Timothy Ray Brown, known as the Berlin patient, is thought to be the first patient ever to be cured of HIV infection."

"Brown, 45, had two bone marrow transplants in Berlin in 2007 and 2008 to treat leukemia that is apparently unrelated to his HIV infection. The blood cells for the transplants came from a donor with a genetic mutation that makes his cells immune to HIV — they lack receptors the virus needs to gain entry to cells. Details about his case were published in the New England Journal of Medicine."
