Figure 1 Frequencies and absolute number of NK cells, CD4+ and CD8+ T cells in different clinical phases. A: Representative dot plots depicting the gating strategy for CD3-CD56+ NK cells, CD56^bright and CD56^dim subsets; B: Frequencies and absolute number of circulating NK cells in different phases; C: Frequencies of CD56^bright and CD56^dim NK cell subsets in different phases; D: Absolute number of CD56^bright and CD56^dim NK cell subsets in different phases; E: Frequencies of CD4+ and CD8+ T cells in lymphocytes in different phases; F: Absolute number of CD4+ and CD8+ T cells in different phases. All data are presented as mean ± SD. NK: Natural killer; HD: Healthy honors; IT: Immune tolerant; IA: Immune active; IC: Inactive carrier; ENEG: Hepatitis B envelope antigen-negative hepatitis.
