Dataset Summary
Title | Global population analysis of HLA class I affinity toward proteasome-generated peptides from five main SARS-CoV-2 spike protein RBD variants |
Description | Here we report binding index of 305 human HLA class I molecules from 18,771 unique haplotypes of 28,104 individuals to the 821 peptides experimentally observed from spike protein receptor-binding domain (RBD) of 5 main SARS-CoV-2 strains hydrolysed by human proteasomes with constitutive and immuno catalytic phenotypes. Our data read that 4 point mutations in the C-terminal RBD region 496-505 of Omicron B1.1.529 strain results in a dramatic increase of proteasome-mediated release of two public HLA class I epitopes covering 82% and 27% of world population haplotypes. Global population analysis of HLA class I haplotypes specific to these peptides demonstrated decreased mortality of human populations bearing these haplotypes to COVID-19 after but not before December, 2021, when Omicron spread over the world and became dominant SARS-CoV-2 strain. Analysis of population frequency of HLA class I alleles revealed that HLA-B*07:02, -B*08:01, -B*15:01, -C*01:02, -C*06:02 and -C*07:02 potentially provides increased resistance of human population to Omicron. Concluding, we found direct experimental observation, which might be one of the key factors that forced the SARS-CoV-2 virus to cross back the red line of pandemic status. |
