title: HIV-1-induced depletion of CD4+ T cells in the gut: mechanism and therapeutic implications.
abstract: The mechanism of CD4+ T cell depletion remains a central unresolved issue in AIDS research. Recent studies have examined the massive depletion of CD4+ T cells observed in macaque models of acute HIV infection. A key question is whether the observed CD4+ T cell death is due to direct consequences of viral infection and to indirect mechanisms including increased expression of mediators of T-cell apoptosis. The therapeutic implications of the early CD4+ T cell loss are discussed.
