One man cured of HIV
14 Dec 2010
This would be pretty amazing if it could be consistently replicated.
Doctors who carried out a stem cell transplant on an HIV-infected man with leukaemia in 2007 say they now believe the man to have been cured of HIV infection as a result of the treatment, sale which introduced stem cells which happened to be resistant to HIV infection.
The man received bone marrow from a donor who had natural resistance to HIV infection; this was due to a genetic profile which led to the CCR5 co-receptor being absent from his cells. The most common variety of HIV uses CCR5 as its â€˜docking stationâ€™, site attaching to it in order to enter and infect CD4 cells, and people with this mutation are almost completely protected against infection.
