The study found that the polysaccharide fraction SGP from ginseng can activate macrophages through the MAPK and NF-kappa B signaling pathways, increasing the production of nitric oxide and cytokines. This may help in maintaining homeostasis during viral and bacterial infections.
Panax ginseng C.A. Meyer (ginseng) has shown immune-enhancing activity in many studies. The purpose of the present study was to analyze the chemical properties of a polysaccharide fraction (SGP) purified from heat- processed ginseng and to evaluate its immune-enhancing activity using RAW264.7 macrophages. The results showed that SGP increased inducible nitric oxide synthase expression and nitric oxide production in RAW264.7 macrophages. In addition, SGP increased mRNA expression and secretion of interleukin 6 and tumor necrosis factor alpha. Immunoblotting results showed that SGP increased the phosphorylation of mitogen-activated protein kinases (MAPKs) and NF-kappa B subunit p65 at 500 mu g/mL and 1000 mu g/mL. Taken together, SGP can activate macrophages through the MAPK and NF-kappa B signaling pathways, and it may help maintain homeostasis during viral and bacterial infections.
