Background & Aims: HLA class I alleles are linked to spontaneous control of hepatitis C virus (HCV) and human immunodeficiency virus-1, but for HCV the roles of particular alleles and corresponding CD8(+) T-cell responses remain incompletely defined. We aimed to determine the correlations between these alleles and natural outcomes of HCV and determine associated key T-cell responses.
Methods: In a cohort of HCV individuals, we determined HLA class I alleles, HCV outcomes, T-cell responses, and examined sequence data for mutational changes within key epitopes.
