Homing chemokine
Web6 jan. 1998 · Chemokines have been shown to activate β 1 or β 2 integrins on monocytes, neutrophils, and lymphocytes and to serve as chemoattractants for these cells during inflammation ( 13 – 15 ). Circumstantial evidence suggests that they may perform similar functions during lymphocyte homing. WebShare free summaries, lecture notes, exam prep and more!!

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. Meer weergeven 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 … Meer weergeven Chemokines are functionally divided into two groups: • Homeostatic: are constitutively produced in certain tissues and are responsible for basal Meer weergeven • Monocytes / macrophages: the key chemokines that attract these cells to the site of inflammation include: CCL2, CCL3, CCL5, … Meer weergeven Members of the chemokine family are divided into four groups depending on the spacing of their first two cysteine residues. Thus the nomenclature for chemokines is, e.g.: CCL1 for the ligand 1 of the CC-family of chemokines, and CCR1 for its respective … Meer weergeven The major role of chemokines is to act as a chemoattractant to guide the migration of cells. Cells that are attracted by chemokines follow a signal of increasing chemokine … Meer weergeven The main function of chemokines is to manage the migration of leukocytes (homing) in the respective anatomical locations in inflammatory and homeostatic processes.

Chemokines are chemoattractant proteins that participate in homeostatic processes, including lymphocyte homing to secondary lymphoid organs, e.g., lymph nodes and Peyer’s patches, as well as in pathologic conditions such as inflammation, tumor growth, and metastasis.
Web31 mei 2024 · Here, we review the molecular mechanisms underlying MSC homing, based on a multistep model involving (1) initial tethering by selectins, (2) activation by cytokines, (3) arrest by integrins, (4) diapedesis or transmigration using matrix remodelers, and (5) extravascular migration toward chemokine gradients.
