It has been known since the 1980s that the progression of human immunodeficiency virus (HIV) was highly variable. In the absence of treatment, some persons succumbed quickly to the virus; others lived for more than 10 years without any sign of immunologic damage. Persons who successfully control the HIV without treatment have been actively studied with the hope of revealing clues that could be used to improve treatment for others, but so far, immunologic treatments for HIV/AIDS have been elusive.
