Abstract:
This study was aimed to investigate the effect of baicalin on the proportion of Th22 cells and the concentration of IL-22 bothin vivo andin vitro, in order to explore the immune mechanism of baicalin on inflammatory bowel disease mice model. The 3.5% dextran sodium sulfate (DSS) was used on C57BL/6 mice for the establishment of colitis mice model. Mice were randomly divided into the blank control group, model group, and baicalin group. Flow cytometry and ELISA were used in the detection of the proportion of Th22 cells and concentration of IL-22 in peripheral blood serum, respectively. The spleen lymphocytes of mice were isolated and cultured by baicalin medium (0, 10, 20, 40μM) for 48 h. Flow cytometry was used in the detection of the proportion of Th22 cells. The results showed that baicalin reduced the proportion of Th22 cells and the expression of IL-22 bothin vivo andin vitro experiments. It was concluded that baicalin can inhibit Th22 cell differentiation and expression of IL-22in vitro and DSS-induced colitis mice. It indicated that baicalin had a good treatment potential in Th22 cell-mediated inflammatory diseases.
