As shown in Figures 3(f) and 3(g), TGF-β and IL-10 levels, as the major cytokines participating in Treg immune function, were markedly reduced in mice with DSS-induced colitis compared with those in the Con group (p < 0.05); in contrast, mice in the Fro, Cp, and Cs group showed markedly enhance expression of TGF-β and IL-10 compared with mice in the DSS-induced colitis group (p < 0.05). This evidence concerns the gene TGFB1 and colitis.
