Human Immunodeficiency Virus Type 1 Tat Induces Apoptosis and Increases Sensitivity to Apoptotic Signals by Up-Regulating FLICE/Caspase-8

Abstract excerpt

Apoptosis contributes to the loss of CD4 cells during human immunodeficiency virus type 1 (HIV-1) infection. Although the product of the env gene, gp160/gp120, is known to play a role in cell death mediated by HIV-1, the role of other HIV-1 genes in the process is unclear. We found that HIV-1 lacking the env gene (HIVDeltaenv) still induced apoptosis in T-cell lines and primary CD4 T cells. The ability to induce...
