细胞素是免疫细胞分泌的激素样介质,是一类在细胞间起联络作用的蛋白质。主要有白细胞介素(IL)、肿瘤坏死因子(TNF)和集落刺激因子等。其中比较重要的白细胞介素是指在白细胞间起作用的一类蛋白质或多肽因子,它在免疫调控中起重要作用;TNF主要由巨噬细胞分泌、在肿瘤免疫和抗感染免疫中有十分重要的意义。细胞素的靶细胞包括免疫和非免疫细胞,因此它的生理、病理作用常超出免疫系统,某些特殊的细胞素还与心血管、骨骼、关节、皮肤和其它疾病的发生有关。签于细胞素的重
Cytokines are hormone-like mediators secreted by immune cells and are a class of proteins that play a role in the intercellular communication. Mainly interleukin (IL), tumor necrosis factor (TNF) and colony stimulating factor. Among them, the most important interleukins are a class of protein or polypeptide factors that play a role in leukocytes. They play an important role in immune regulation. TNF is mainly secreted by macrophages and plays a very important role in tumor immunity and anti-infective immunity Meaning. Cytokines target cells, including immune and non-immune cells, so its physiological and pathological effects often beyond the immune system, some of the special cytokines also with cardiovascular, bone, joint, skin and other diseases.
