WebChemokine. Chemokines (from Ancient Greek χῠμείᾱ (khumeíā) 'alchemy', and κῑ́νησῐς (kī́nēsis) 'movement'), or chemotactic cytokines, are a family of small cytokines or signaling proteins secreted by cells that induce directional movement of leukocytes, as well as other cell types, including endothelial and epithelial cells. WebChemoattractants are small soluble molecules that bind to receptors on leukocytes causing their stimulation, polarization, and locomotion, in part through the activation of the integrin adhesion molecules. Leukocyte locomotion toward higher concentrations of a chemoattractant is referred to as chemotaxis, and this can occur in a hierarchal manner.
