Title: Control of HIV 1 replication in vitro by vaccine induced human CD8 T cells through conserved subdominant Pol epitopes
Abstract: The specificity of CD8(+) T cells is critical for early control of founder/transmitted and reactivated HIV-1. To tackle HIV-1 variability and escape, we designed vaccine immunogen HIVconsv assembled from 14 highly conserved regions of mainly Gag and Pol proteins. When administered to HIV-1-negative human volunteers in trial HIV-CORE 002, HIVconsv vaccines elicited CD8(+) effector T cells which inhibited replication of up to 8 HIV-1 isolates in autologous CD4(+) cells. This inhibition correlated with interferon-γ production in response to Gag and Pol peptide pools, but direct evidence of the inhibitory specificity was missing. Here, we aimed to define through recognition of which epitopes these effectors inhibit HIV-1 replication.
