Medicinal mushroom Ganoderma lucidum (Leyss: Fr) Karst. triggers immunomodulatory effects and reduces nitric oxide synthesis in mice.
This study investigated the effect of Ganoderma lucidum supplementation on lymphocytes and peritoneal macrophages from mice. Our results show that G. lucidum in vivo was able to increase interferon-gamma (IFN-gamma) concentration but reduced CD3(+) and CD8(+) spleen lymphocytes. Ex vivo, IFN-gamma; and interleukin-10 levels were increased and the tumor necrosis factor-alpha (TNF-alpha) level was reduced by peritoneal macrophages from mice fed with G. lucidum. In the absence of stimuli nitric oxide production was reduced in mice fed with G. lucidum, and with lipopolysaccharide stimulation nitric oxide production was increased but was lower than control values (P < .05). G. lucidum was grown by solid-state culture in wheat grain, and a chow containing 10% G. lucidum mycelium was formulated (G10). Swiss male mice were divided into two groups, termed G10 and control groups according to the diet, and were fed for 3 months. Peritoneal macrophages were obtained and investigated with regard to phagocytosis, lysosomal volume, hydrogen peroxide, superoxide anion, and cytokines ex vivo. In the plasma we investigated concentrations of cytokines, and in the spleen we determined subsets of CD3(+), CD4(+), CD8(+), and CD19(+) lymphocytes.
