Abstract
In order to determine the functional benefits of $Cordyceps$ $militaris$ in the immune system, we examined the immunomodulatory activities of $Cordyceps$ $militaris$ in an immunocompromised C57BL/6 mice model. Mice were injected intraperitoneally with an immunosuppressive drug, cyclophosphamide, and then administered orally with 3% hydroxypropylmethylcellulose or 30, 100, and 300 mg/kg of 50% ethanol extract of $Cordyceps$ $militaris$ (CM 30, CM 100, and CM 300, respectively) for 12 days. Mice treated with CM displayed significantly increased splenocyte proliferation and natural killer cell activity compared to immunosuppressed control mice (p<0.05). The spleen cells isolated from mice treated with CM also displayed increased production of Th1 cytokines, including IL-2, IL-12, IFN-${\gamma}$ and TNF-${\alpha}$, suggesting enhanced cellular immunity in response to CM. However, CM had no significant effect on the production of IL-4 and IL-10. These results indicate that $Cordyceps$ $militaris$ enhances immune function by promoting immune cell proliferation and Th1 cytokine production.
