Abstract

The impact of naïve precursor frequency on human virus-specific CD8+ T cell immunodominance is not well understood. Using a recently developed MHC class I tetramer enrichment protocol, we found a conserved hierarchy and >10-fold difference in naïve precursor frequencies across three HLA-A2 restricted HCV-specific epitopes. Importantly, the NS31406 epitope with the highest naïve precursor frequency in healthy donors was also the most frequently targeted epitope in a large cohort of chronically HCV-infected patients, both ex vivo and after in vitro stimulation. These results indicate for the first time that immunodominance in a human viral infection is linked to naïve precursor frequency.
