细胞因子是由机体的免疫细胞和非免疫细胞合成及分泌的小分子多肽物质，它们能调节其它细胞并发挥细胞的生理功能，在机体对疾病防御及损伤修复过程中起重要作用。但产生过多又可加重组织损伤，过去主要在免疫、炎症性疾病中研究细胞因子；近年来随着分子生物学技术的发展... Cytokines are small molecule polypeptide substances synthesized and secreted by the body’s immune and non-immune cells. They regulate other cells and exert the physiological functions of the cells and play an important role in disease defense and injury repair. However, excessive and can increase tissue damage, the past mainly in immune, inflammatory diseases in the study of cytokines; in recent years with the development of molecular biology technology ...
