Abstract

Discusses a study which shows that the high prevalence of HIV in Africa creates conditions for natural selection of variants that affect the time between HIV infection and the onset of AIDS. Selection pressures exerted on CCR5, a cell-surface receptor for chemokines; Expectation that the HIV epidemic will also affect alleles associated with resistance to HIV infection; Other genetic factors that might increase resistance to AIDS.

Abstract

Reports that a study of the immune responses in sex workers in Nairobi, Kenya, revealed that women who remain seronegative for HIV for several years mounted cytotoxic T lymphocyte responses to a different set of epitopes than those who were HIV positive. Trial of a vaccine that includes the seronegative-specific isotopes; Difficulty of developing a vaccine in Africa, because of genetic variability of the virus and the host population; Outlook for another vaccine that is being tested.
