Astragalus polysaccharide enhances the immune function of RAW264.7 macrophages via the NF‑κB p65/MAPK signaling pathway

The aim of the present study was to investigate the immunoregulatory effects of Astragalus polysaccharide (APS) on RAW264.7 cells. The production of cytokines by RAW264.7 cells was analyzed using ELISA, while cell viability and optimal concentration of APS were assessed using the Cell Counting Kit‑8 assay. In addition, the mRNA levels of IL‑6, inducible nitric oxide synthase (iNOS) and TNF‑α were determined by reverse...
