A biologically active substance taken from the drug has the ability to promote immune functions such as T, B, CTL, NK and macrophages, and promote the production of cytokines such as IL-2, IL-3 and TNFβ. To enhance the immune function and regulate the neuroendocrine immune regulation (NIM) network in mice bearing tumor, chemotherapy and radiation injury, this paper reviews the progress of research on the immune regulation of Lycium barbarum polysaccharide in recent years [1] . Light yellow fibrous solid, with various effects of regulating immunity and delaying aging, and can be used as medicine. |
