Antiretroviral drug therapy alters the profile of human immunodeficiency virus type 1-specific T-cell responses and shifts the immunodominant cytotoxic T-lymphocyte response from Gag to Pol.

Abstract excerpt

Antiretroviral drug therapy and cytotoxic T lymphocytes (CTL) both exert selective pressures on human immunodeficiency virus type 1, which influence viral evolution. Compared to chronically infected, antiretroviral-untreated patients, most chronically infected, treated patients with detectable viremia lack a cellular immune response against the Gag 77-85(SL9) epitope but show a new immunodominant response against...
