The immune system plays an important role in maintaining and protecting human health. In the present study, comparison of immuno-modulatory activities between polysaccharides (SFP) and ethanol (SFE) extracts separated from Sargassum fulvellum in macrophages and murine splenocytes were investigated. Immuno-modulatory activities of macrophages were estimated based on cell proliferation, nitric oxide (NO), inducible NO synthase (iNOS), and cytokine production in RAW 264.7 macrophage cells, and lipopolysaccharide was used as a positive control. SFP and SFE treatment did not affect cytotoxicity in RAW 264.7 macrophage cells, and SFP treatment significantly increased NO and cytokine production (, IL-6, and ), whereas SFE did not contribute to the increase in NO and cytokine production. In the case of splenocytes, SFP treatment increased splenocyte proliferation and also highly increased production of Th-1 type cytokines (IL-2 and ) than those of SFE. Through this study, we confirmed that immuno-modulatory activities of Sargassum fulvellum may be due to polysaccharide extracts and this can be a potential nutraceutical.
