Research Advances in Immunomodulation and Antitumor Activity of Polysaccharides
多糖免疫调节和抗肿瘤研究进展

Enhancing immunity and antiturnor activity is the important biological activity of polysaccharide. Studies showed that it enhanced immunity through improving the activity of immtmocyte, activising the secretion of cell factor, inducing the production of antibody and activising the complementary system, etc. The antitumor ways of polysaccharide mainly were inhibiting the growth of cancer cells and the synthesis of protein and nuclear acid in the cells, inducing apoptosis, affecting the expression of cancer gene and changing the growing specialities of the cancer cell membrane. In this review, research advances in the field of immunomodulation and antitumor activity ofpolysaccharides in recent years were briefly summarized and analysed.
