OBJECTIVE:To investigate immunomodulatory effects of Astragalus polysaccharides(APS)on the co-culture of peripheral blood mononuclear cells(PBMCs)with He La cervical cancer cell ***:To assess the proliferation of PBMCs,carboxyfluorescein succinimidyl ester(CFSE)-labeled PBMCs were co-cultured with He La cells and treated with different concentrations of *** of cell culture were collected for cytokines assay via enzyme-linked immunosorbent assay(ELISA).The impact of APS on the proliferation of PBMCs,induction of regulatory T cells(Tregs),and myeloid-derived suppressor cells(MDSCs)was carried out by flow ***:It was observed that APS could increase the proliferation of PBMCs co-cultured with He La cells(P0.05).Furthermore,ELISA results demonstrated that APS could decrease IL-10 and TGF-βconcentration(P<0.05).CONCLUSION:The above-mentioned characteristics showed that APS might be able to modulate immune responses and improve anti-tumor effects through increasing the proliferation of PBMCs and decreasing inhibitory cytokines secretion as critical mediators of immune suppression in the tumor microenvironment.
