Cytokines
Cytokine (CK) is a low molecular weight soluble protein induced by immunogens, mitogens or other stimulants. It has many functions in regulating innate and adaptive immunity, hemocytogenesis, cell growth, APSC pluripotent cells and damaged tissue repair. Cytokines can be divided into interleukins, interferons, tumor necrosis factor superfamily, colony-stimulating factors, chemokines, growth factors and so on. Multicellular cytokines play a role in vivo through paracrine, autocrine or endocrine ways, with pleiotropic, overlapping, antagonistic, synergistic and other physiological characteristics, forming a very complex cytokine regulatory network, involved in a variety of important physiological functions of the human body.
