摘要

The specific mechanisms underlying the var- ied susceptibility of HIV-infected (HIV+) individuals to op- portunistic infections (OI) are still incompletely understood. One hypothesis is that quantitative differences in specific T cell responses to a colonizing organism determine the devel- opment of an AIDS-defining OI. We evaluated this hypothesis for herpes simplex virus (HSV) infection, a common OI in HIV+ patients. Using limiting dilution analyses, the fre- quency of HSV-specific CD8~+ cytotoxic T lymphocyte precur- sors (pCTL) and proliferative precursors were quantitated in peripheral blood mononuclear cells from 20 patients coin- fected with HIV and HSV-2.
