VD stimulated the expansion of Tregs and increased IL-10 production. The absolute number (A) and the proportion (B) of CD4+CD25+Foxp3+ Tregs were quantified by flow cytometry. The concentrations of IL-10 secreted by cultured splenocytes (C) and in the mouse serum (D) were determined by ELISA. Results are representatives of three independent experiments. Values are presented as the mean ± SEM (n = 5 mice per group). * and ** indicate significant differences between the values in PbA-infected mice and the baseline levels on day 0 at P<0.05 and P<0.01, respectively. # and ## indicate significant difference between the PbA and PbA+VD groups at P<0.05 and P<0.01, respectively.
