Investigation of immunomodulatory activity of hericium erinaceus on cyclophosphamide-induced immunosuppression in mice

The study  was conducted to assess the immunostimulatory effect of Hericium Erinaceus on cyclophosphamide-induced immunodeficient mice. Animals were  administered Hericium Erinaceus orally at 0.72 g/kg b.w and 1.44 g/kg b.w for seven consecutive days. On the 4th day, CP (200 mg/kg) was intraperitoneally injected into mice. The results illustrated that Hericium Erinaceus at 0.72 g/kg b.w only posed an immunostimulating potency in the cyclophosphamide-induced immunosuppression model. Besides, Hericium Erinaceus at 1.44 g/kg b.w ameliorated the effects of CP on delayed-type hypersensitivity (DTH) response, relative spleen weight, serum IL-2, TNF-α concentration, and micro-histological images of spleen and thymus substantially. This suggested the potential of Hericium Erinaceus to treat immunosuppression diseases in clinical practice.
