WebChemokines and their receptors otherwise tend to interact indiscriminately to stimulate upregulation of adherent chemokines, co-stimulatory cytokines and signaling cascades … Inflammatory chemokines function mainly as chemoattractants for leukocytes, recruiting monocytes, neutrophils and other effector cells from the blood to sites of infection or tissue damage. Certain inflammatory chemokines activate cells to initiate an immune response or promote wound healing. See more 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 … See more Chemokines are functionally divided into two groups: • Homeostatic: are constitutively produced in certain tissues and are responsible for basal leukocyte migration. These include: CCL14, CCL19, CCL20, CCL21, CCL25, CCL27 See more • Monocytes / macrophages: the key chemokines that attract these cells to the site of inflammation include: CCL2, CCL3, CCL5, CCL7, CCL8, CCL13, CCL17 and CCL22. • T-lymphocytes: the four key chemokines that are involved in the recruitment of T … See more The major role of chemokines is to act as a chemoattractant to guide the migration of cells.

WebThe CC cytokines are proteins characterized by two adjacent cysteines. The cytokine encoded by this gene may play a role in normal lymphocyte recirculation and homing. It also plays an important role in trafficking of T cells in thymus, and in T cell and B cell migration to secondary lymphoid organs.
