The clearances of serum HBsAg, HBeAg, and HBV DNA were significantly delayed in mice transferred with CD8+ T cells from CH mice (CT mice) compared to those in mice transferred with CD8+ T cells from AR mice (AT mice) (Figure 2B, left panel, HBsAg, P = 0.017; Figure 2C, left panel, HBeAg, P = 0.049; Figure 2D, HBV DNA, P = 0.021). This evidence concerns the gene CD8A and cyclic hematopoiesis.
