Soluble mimics of a chemokine receptor: Chemokine binding by receptor elements juxtaposed on a soluble scaffold

cxcr4: a potential chemokine receptor for future regenerative therapeutic target

understanding the molecular mechanisms in regeneration could help the stem cell therapists to improve the clinical practices and could be considered a major milestone in the translation of stem cell research to clinics. chemokines have been described as one of the most significant singling networks in stem cells homing and regeneration of damaged organs. cxcr4/cxcl12 has been known as a key pla...

Preparation and preliminary biological evaluation of [153Sm] samarium AMD3100; towards a possible therapeutic chemokine receptor CXCR4 targeting complex

Introduction: In continuation of recent development of possible C-X-C chemokine receptor type 4 (CXCR4) imaging agents, we report the development of a possible CXCR4 targeted therapy agent. Methods: [153Sm]labeled 1,1′-[1,4-phenylenebis(methylene)] bis-1,4,8,11-tetraazacyclo -tetradecane ([153Sm]-AMD3100) was prepared using [153Sm]SmCl3 and AMD-3100 ...

Chemokine Receptor-Targeted Library

Identification of the binding site for a novel class of CCR2b chemokine receptor antagonists: binding to a common chemokine receptor motif within the helical bundle.

Monocyte chemoattracant-1 (MCP-1) stimulates leukocyte chemotaxis to inflammatory sites, such as rheumatoid arthritis, atherosclerosis, and asthma, by use of the MCP-1 receptor, CCR2, a member of the G-protein-coupled seven-transmembrane receptor superfamily. These studies identified a family of antagonists, spiropiperidines. One of the more potent compounds blocks MCP-1 binding to CCR2 with a ...

Murine astrocytes express a functional chemokine receptor.

Elevated levels of chemokines have been observed in various diseases of the CNS. Little is known, however, about how these chemokines affect parenchymal cells of the CNS. The current studies examine astrocyte chemotaxis to the mouse chemokine macrophage inflammatory protein-1alpha (MIP-1alpha). Murine astrocytes demonstrate directed migration along a chemical gradient in response to 10(-10)-10(...
