Abstract

This study was performed to study the effects of astragalus polysaccharides (APS) in the treatment of ulcerative colitis (UC), and to explore whether myeloid-derived suppressor cells (MDSC) involve in this process. UC model was established by dextran sulfate sodium salt (DSS) inducement in mouse. Then the effects of APS on UC was evaluate at the levels of cytology and molecular biology: exploring the influence of APS on MDSC by analyzing the levels of MDSC before and after the treatments of APS; evaluating the therapeutic effects of APS on UC by pathologic histology. Data showed that the levels of MDSC in bone marrow, spleen, peripheral blood of UC mice were significantly decreased after intervention with APS, indicating APS inhibited the level of MDSC significantly. After depletion bone marrow cells in mice, we further found that the therapeutic effects of APS in MDSC- group was significantly reduced compared with MDSC+ group. It was discovered through pathological analysis that, compared with UC model group, APS intervention group mainly manifested as reduced infiltrating acute and chronic inflammatory cells, necrotic epithelial cells and epithelial ulceration. Therefore, APS could reduce the inflammatory cell infiltration in colonic tissues of UC model mice, repair the damaged colonic mucosa, and promote ulcer healing. In conclusion, APS has a potential application in the treatment of ulcerative colitis, and is dependent or partially dependent on MDSC to achieve this effects.
