WebMay 1, 2024 · Curing HIV infection will require the elimination of a reservoir of infected CD4+ T cells that persists despite HIV-specific cytotoxic T cell (CTL) responses. Although viral latency is a critical factor in this persistence, recent evidence also suggests a role for intrinsic resistance of reservoir-harboring cells to CTL killing. This resistance ... WebNov 30, 2024 · HLA-restricted CTL responses are associated with better control of viremia during primary HIV infection [48,49] and differential rates of clinical disease progression [50,51]. Thus, the reduced expression of HLA-A and HLA-B molecules on the surface of infected cells can protect them from CTL recognition and elimination [ 52 ].
