Arabinoxylan (Ara) rice bran has been shown to be a potent biological response modifier as manifested by stimulation of different arms of the immune system. We examined the effects of Ara rice bran and exercise on the immune function and cytokines in lipopolysaccharide (LPS)-stimulated rats. As the results, tumor necrosis factor-α as representative inflammatory cytokines showed a significantly lower in Ara supplement group, thus the Ara rice bran had a higher inhibitory activity than the both exercise and control group. However, 4 weeks of exercise training significantly increased inflammatory reactions rather than treatment with Ara in LPS-treated rats. The Ara rice bran acted to decrease the inflammatory reaction. These results suggest that the supplement of Ara rice bran is likely contribute to inflammation response and the Ara rice bran can be used as a possible safe alternative to the immunotherapeutic modalities.
