Immunomodulatory activity in vitro and in vivo of polysaccharide from Potentilla anserina

The polysaccharide (PAP) from Potentilla anserina was evaluated for modulating effects by using mouse peritoneal macrophage and the immunosuppressed-model cyclophosphamide-induced. Phagocytotic and mononuclear phagocytic system function assays showed that PAP stimulated the phagocytosis of phagocyte. Splenocyte proliferation assay showed that PAP acted the effect combining Con A or LPS in splenocyte proliferation. The parameters detected showed that PAP increased thymus and spleen indices, the levels of LDH and ACP in the spleen, and IL-10and IFN-γ in serum in immunosuppressed mice. The results suggest that PAP is involved in immunomodulatory effects leading to the exploration for PAP as a potential immunostimulant.
