T-cell receptor recognizing HIVconsv-derived peptide-MHC complexes (HIVconsv-specific TCR)

T-cell receptors (TCRs) recognizing HIVconsv-derived peptide-MHC complexes are specialized immune receptors that target highly conserved regions of the HIV-1 proteome. These TCRs are typically elicited by the HIVconsv vaccine, which incorporates 14 of the most conserved segments of the HIV-1 genome to overcome the virus's high mutational diversity (Létourneau et al., 2007, PLoS ONE). By focusing the T-cell response on these invariant regions, these TCRs aim to provide broad protection across different HIV-1 clades and prevent viral escape (Hanke, 2019, Curr Opin HIV AIDS). In therapeutic contexts, these TCRs are studied for their potential in adoptive T-cell transfer (TCR-T therapy) and as benchmarks for vaccine efficacy (Borthwick et al., 2014, Mol Ther). They function by binding to specific HIV peptides presented by MHC Class I (for CD8+ T cells) or Class II (for CD4+ T cells) molecules, leading to the elimination of infected cells and the orchestration of a robust antiviral immune response (Mutua et al., 2014, PLoS ONE). The development and characterization of these TCRs are central to strategies aimed at achieving a functional cure for HIV.
