Relative expression of selected genes in IgM⁺κ⁺CD27⁺ B cells determined by quantitative RT-PCR. Values are normalized to RPS11 for cDNA content and to a universal standard RNA. Comparisons between groups were made using the Kruskal-Wallis test, and P values for HCV⁺MC⁻ compared with HCV⁺MC⁺ subjects were computed using Dunn post test. N.S. indicates not significant (P > .05).
