A London man has been in remission from HIV for a year and a half, without drugs, after receiving a stem cell transplant of virus-resistant cells — raising the prospect that he has become the second person to ever be cured of the disease.
The "London patient" case, cautiously reported in the journal Nature as still too "premature" to be declared a cure, comes a decade after Timothy Brown, known in medical circles as the "Berlin patient" was cured by a similar stem cell transplant, galvanizing the field of HIV research and sparking the search for a cure.
