免疫细胞(T 细胞与 B 细胞、其他淋巴细胞、单核巨噬细胞及粒细胞)在炎症、创伤和免疫应答中分泌的激素样介质称细胞因子(Cytokines),或称肽类调节因子,为分子量小于80,000道尔顿的糖蛋白。从50年代发现第一个细胞因子干扰素以后,至今已逾百余种。随着分子生物学研究的进展,大批细胞因子的cDNA 和基因 DNA 克隆已获成功,每年都会有几个新的细胞因子克隆化成功,使细胞因子研究的高潮 The hormone-like mediators secreted by immune cells (T cells and B cells, other lymphocytes, monocyte-macrophages and granulocytes) in inflammation, trauma and immune response are called Cytokines, or peptide regulators, and are Glycoproteins with molecular weights less than 80,000 daltons. More than a hundred species have been found since the first cytokine interferon was discovered in the 1950s. With the progress of molecular biology research, a large number of cytokines and DNA clones have been successfully cloned. Several new clones of clones have been successfully cloned each year, culminating in the study of cytokines
