WebLes chémokines sont des cytokines dont le rôle principal est l’activation cellulaire et la stimulation de la migration des leucocytes. C’est en interagissant avec des récepteurs, exprimés à la surface cellulaire et couplés aux protéines G (GPCRs), qu’elles assurent leurs diverses fonctions. WebCytokines 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.
