PG - 1199-208 AB - The average time between infection with human immunodeficiency virus (HIV) and development of acquired immune deficiency syndrome is approximately 8 years. However, progression rates vary widely, depending on several determinants, including HIV-specific immunity, host genetic factors, and virulence of the infecting strain. In untreated HIV-infected patients with different progression rates, we examined HIV-specific T cell responses in combination with host genetic markers, such as chemokine/chemokine-receptor (CCR) polymorphisms and human leukocyte antigen (HLA) genotypes. HIV-specific CD4(+) T cell responses and, to a lesser extent, HIV-specific CD8(+) T cell responses were inversely correlated with progression rate. Slower progression was not related to polymorphisms in CCR genes, HLA genotype, or GB virus C coinfection. These data suggest that HIV-specific T cell responses are involved in protecting the host from disease progression.
