Honduras HIV cohort: HLA class I and CCR5-Δ32 profiles and their associations with HIV disease outcome

Microbiol Spectr. 2023 Dec 12;11(6):e0161323. doi: 10.1128/spectrum.01613-23. Epub 2023 Nov 14.

Abstract

We identify both canonical and novel human leukocyte antigen (HLA)-HIV associations, providing a first step toward improved understanding of HIV immune control among the understudied Honduras Mestizo population. Our results are relevant to understanding the protective or detrimental effects of HLA subtypes in Latin America because their unique HLA diversity poses challenges for designing vaccines against HIV and interpreting results from such vaccine trials. Likewise, the description of the HLA profile in an understudied population that shows a unique HLA immunogenetic background is not only relevant for HIV immunology but also relevant in population genetics, molecular anthropology, susceptibility to other infections, autoimmune diseases, and allograft transplantation.

Keywords: HIV disease outcome; HLA allele frequencies; HLA haplotype structures; HLA linkage disequilibrium; HLA-HIV disease associations; Honduran Mestizos; Latin America; Mesoamerican Mestizos.
