HIV-1 conserved epitopes in Gag and Pol (HIVconsv)

HIV-1 conserved epitopes in Gag and Pol are highly stable regions of the viral proteome that are essential for viral fitness and less prone to mutational escape [1, 4]. The Gag polyprotein provides the structural framework for the virus, while the Pol polyprotein encodes essential enzymes like protease, reverse transcriptase, and integrase [15, 21]. Because mutations in these regions often result in significant fitness costs for the virus, they are ideal targets for T-cell-based therapeutic vaccines [4, 14]. These vaccines, such as the HIVconsv and HTI candidates, aim to refocus the immune system's T-cell response away from variable, immunodominant "decoy" epitopes toward these conserved "Achilles' heels" of the virus [2, 11]. By eliciting robust CD8+ cytotoxic T-lymphocyte (CTL) responses against these epitopes, researchers hope to achieve long-term viral control or functional cure, often in combination with latency-reversing agents in "kick and kill" strategies [12, 13].
