This study was carried out to evaluate the immunomodulatory capacity of edible mushrooms, including Sarcodon aspratus, Letinus edodes and Grifola frondosa in mice. BALB/c mice were administered 50, 500, and 1000 mg/ kg body weight of various mushrooms five times a week over 4 weeks through oral administration. The control mice were administered distilled water. No significant changes in body weight were observed. IL-4 and IFNγ production was evaluated with splenic T lymphocytes stimulated in vitro with phytohemagglutinins for 48 hr. The mice group administered Sarcodon aspratus, Grifola frondosa tend to higher ratio of IFNγ versus IL-4 than the other groups. In addition, the ratio of plasma IgG2a versus IgG1 was also elevated in mice treated with Sarcodon aspratus. These results indicated that Sarcodon aspratus can enhance type-1 helper T cell-mediated cellular immunity. And also, S. aspratus seems to be one of the most useful mushrooms for immunomedicine.
