Results of the intracellular cytokine staining assay for interleukin 2. (A) Individual responses of CD8+ T cells stimulated by HBV peptide pools in subjects with HBsAg seroclearance (Group1), immunotolerant HBV carriers (Group2) and inactive HBsAg carriers (Group3). (B) Individual responses of CD4+ T cells stimulated by HBV peptide pools in subjects with HBsAg seroclearance, immunotolerant HBV carriers and inactive HBsAg carriers. (C) The mean frequencies of positive CD4+ and CD8+ T cell responses in the three populations. Each bar in 3C represents the mean ± SD percentage of IL-2 secreting CD4+ and CD8+ cells in subjects with positive responses to either the C or S peptide pools.
