Chemokine fractalkine
WebSep 1, 1998 · Although some known chemokine receptors have been shown to be expressed in the CNS, the relative abundance of the rat chemokine receptor-like gene RBS11 in the CNS, coupled with additional fractalkine-concordant expression in other peripheral tissues including lung, kidney, and gut, prompted us to consider the RBS11 … WebFractalkine (CX 3 CL1) is the first described chemokine that can exist either as a soluble protein or as a membrane-bound molecule. Both forms of fractalkine can mediate adhesion of cells expressing its receptor, CX 3 CR1. This activity, together with its expression on endothelial cells, suggests that fractalkine might mediate adhesion of leukocytes to the …

WebApr 15, 2000 · Leukocyte adhesion and trafficking at the endothelium requires both cellular adhesion molecules and chemotactic factors. A newly identified CX 3 C chemokine, fractalkine, expressed on activated endothelial cells, plays an important role in leukocyte adhesion and migration. We examined the functional effects of fractalkine on β 1 and β … WebNov 11, 2003 · CX3CL1 (previously known as fractalkine) is the only member of the CX3C subfamily .Unlike any other chemokine, except CXCL16 , it exists in two isoforms: a membrane-anchored form in which the chemokine module is presented to the cell surface on a long mucin-like stalk and a soluble form that results from proteolytic …
WebThe chemokine fractalkine (CX3CL1)/CX3CR1 receptor-ligand pair was reported to be a communication link between neurons and microglia. CX3CL1 is an inhibitory factor expressed on neurons, and its receptor, CX3CR1, is primarily expressed on microglia ( 13, 71 – 73 ). The combination of these two components keeps microglia quiescent.
