First man ‘functionally cured’ of HIV

Timothy Ray Brown suffered from both leukemia and HIV when he received a bone marrow stem cell transplant in Berlin, Germany in 2007. The transplant came from a man who was immune to HIV, which scientists say about 1 percent of Caucasians are. (According to San Francisco’s CBS affiliate, the trait may be passed down from ancestors who became immune to the plague centuries ago. This Wired story says it was more likely passed down from people who became immune to a smallpox-like disease.)

What happened next has stunned the dozens of scientists who are closely monitoring Brown: His HIV went away.

“He has no replicating virus and he isn’t taking any medication. And he will now probably never have any problems with HIV,” his doctor Gero Huetter told Reuters. Brown now lives in the Bay Area, and suffers from some mild neurological difficulties after the operation. “It makes me very happy,” he says of the incredible cure.
