Resonating with the signaling bias of CXCR7

Molecular Cell, 2022
Kleist et al. combine NMR spectroscopy and residue contact network analysis to identify a potential allosteric network in CXCR7, a β-arrestin-biased chemokine receptor, which links the extracellular ligand-binding pocket and the intracellular transducer-coupling region through the receptor transmembrane core.

CXCR7, CXCR4 and CXCL12: An eccentric trio?

Journal of Neuroimmunology, 2008
CXCR7, formerly called RDC1 is a recently deorphanized G-protein coupled receptor which binds with high affinity the inflammatory and homing chemokines CXCL11/ITAC and CXCL12/SDF-1. Despite its phylogenetic relation and ligand binding properties CXCR7 does not mediate typical chemokine receptor responses such as leukocyte trafficking.

Shifting Signals with CXCR7

Science Signaling, 2011
CXCR7 heterodimerizes with CXCR4, leading to preferential activation of β-arrestin–mediated signaling pathways.

The novel chemokine receptor CXCR7 regulates trans-endothelial migration of cancer cells

open access: yesMolecular Cancer, 2011
Background Migration of metastatic tumor cells from the bloodstream into lymph nodes is thought to be facilitated by expression of the chemokine receptors CCR7, CXCR4 and, for B cell-derived tumors, CXCR5. Expression of their respective chemokine ligands

SDF‐1α induces differential trafficking of CXCR4‐CXCR7 involving cyclophilin A, CXCR7 ubiquitination and promotes platelet survival

The FASEB Journal, 2014
ABSTRACT Platelet‐derived SDF‐1α (CXCL12) mediates inflammatory and regenerative mechanisms. The present study characterizes the effect of SDF‐1α ligation in platelets. SDF‐1α (0–100 μM) dose and time dependently caused internalization of its receptor CXCR4 (28.9±1.6 vs . 16.

Atorvastatin inhibits CXCR7 induction to reduce macrophage migration

Biochemical Pharmacology, 2014
We have recently reported that CXCR7, the alternate high affinity SDF-1 receptor, is induced during monocyte-to-macrophage differentiation, leading to increased macrophage phagocytosis linked to atherosclerosis. Statins, the most widely used medications for atherosclerosis, were shown to have pleiotropic beneficial effects independent of their ...

Activation of CXCR7 receptor promotes oligodendroglial cell maturation

Annals of Neurology, 2010
AbstractObjective:Differentiation of oligodendroglial precursor cells is crucial for central nervous system (re)myelination and is influenced by multiple extrinsic and intrinsic factors. Chemokines, a group of small proteins, are highly conserved among mammals and have been implicated in a variety of biological processes during development, tissue ...
