Study on Immunostimulating Activity of Macrophage Treated with Purified Polysaccharides from Liquid Culture and Fruiting Body of Lentinus edodes

초록

Lentinus edodes is a well-known edible and medicinal mushroom used in Oriental cultures. Recently, L. edodes has attracted a lot of attention owing to its antifungal activity, antibacterial activity, antiviral activity, hepatoprotective effect, antitumor activities, and immunomodulatory and cytotoxic effects. In this study, the water-soluble crude polysaccharides, CPF and CPB, which were obtained from the fruiting body and culture cell-free broth of L. edodes by hot-water extraction and ethanol precipitation, were fractionated by DEAE cellulose and Sepharose CL-6B column chromatography, resulting in. six polysaccharide fractions, CPFN-G-I, CPFN-G-II, CPFN-G-III, CPFA-G, CPBN-G, and CPBA-G Among these fractions, CPFN-G-I, CPBN-C., and CPBA-G were shown to stimulate the functional activation of macrophages including NO production, cytokine expression, and phagocytosis.
