Just recently a second person had a long remission from HIV (meaning that no new HIV viral particles have been replicating in his body) after a haematopoetic stem cell transplant (transplantation of bone marrow, basically. All the precursors to new blood cells are from a donor and don't have a receptor that the viral particle needs to enter the cell) It's a major breakthrough in the treatment of HIV.
