In this study, the anti-inflammatory activity of an extract of the fruiting body of the Tuber himalayense (TH) truffle collected from oak growing areas in Korea was investigated. The extract was not cytotoxic at concentrations below 100 μg/mL in an experiment evaluating inflammation inhibitory effect in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. LPSinduced nitric oxide (NO) and prostaglandin E2 (PGE2) production was inhibited by the extract in a concentration-dependent manner. Western blot assay results indicated that the anti-inflammatory activity of TH extract was likely caused by the reduced production of NO and PGE2 via suppression of induced NO synthase and cyclooxygenase-2 gene expression. In addition, TH extract effectively inhibited the production of interleukin (IL)-1β and IL-6 by macrophages. Thus, TH extract effectively inhibits the overexpression of various inflammatory mediators and could be valuable in formulating anti-inflammatory foods and medicines that target these components.
