Influence of expected HLA-DPB1 expression on HCV viremia and HCV-specific T-cell responses during and after pregnancy. (A) Comparison of change in viral load from third trimester to 3-mo postpartum among women categorized by their number of high-expression HLA-DPB1 alleles. (B–D) Longitudinal differences in viral load (B) and HCV-specific IFN-γ ELISpot breadth (C) and magnitude (D) between women with (gray shaded) and without (white shaded) at least one high-expression HLA-DPB1 allele. P value summary: ns, P ≥ 0.05; *P < 0.05; **P < 0.01; ***P < 0.001.
