Abstract
ABSTRACT Immunosenescence is the degeneration of immunological organs and cells due to aging. Some plants and fungi may have anti-aging benefits through regulating immunosenescence. In this study, mice were fed with two dietary supplement products: Zeng Jian Health Tonic (ZJ) contains extracts from Lentinula edodes, Poria cocos, Tremella fuciformis, cassia seed, Flammulina velutipes, Fructus lycii, chrysanthemum, and mulberry. Zhen Yuan Capsule (ZY) contains extracts from Ganoderma lucidum, Semen cuscutae, Poria cocos, Schisandra chinensis, Codonopsis pilosula, and Atractylodes macrocephala. In addition, the immune organ index, immune cell functions, inflammatory cytokines, and antioxidant enzyme activities were evaluated. The combination of ZJ and ZY could restore the function of lymphocytes and NK cells; decrease the level of pro-inflammatory cytokines including IL-1α, IL-1β, and GM-CSF; increase the level of anti-inflammatory cytokine IL-5; and enhance superoxide dismutase and glutathione peroxidase activities. Therefore, combining ZJ with ZY has anti-aging effects on elderly mice.
