Cytokines mechanism of action
Cytokines have been classed as lymphokines, interleukins, and chemokines, based on their presumed function, cell of secretion, or target of action. Because cytokines are characterised by considerable redundancy and pleiotropism, such distinctions, allowing for exceptions, are obsolete. The term … See more Cytokines are a broad and loose category of small proteins (~5–25 kDa ) important in cell signaling.
