objective(s) alzheimer’s disease (ad) is a complex disease with multifactorial etiology. inflammation has been proven to have an important role in the pathogenesis of ad. both ccr2 and ccr5 genes expression increase in ad patients comparing to control subjects. ccr5 gene encodes a protein which is a member of the beta chemokine receptors family of integral membrane proteins. ccr5-δ32 is a genet...

Both CCR2 and CCR5 genes expression increase in AD patients comparing to control subjects.

chemokines and their receptors  play an important  role in the  late inflammatory stage of asthma. in this study, we aimed to investigate polymorphisms of mcp-1 (ccl2), ccr2 and ccr5 which can affect qualitatively and/or quantitatively their production and thus influence both susceptibility and severity of asthma and its clinical and biological features. mcp-1   (a/g   -2518),  ccr2   (+/64i), ...

The biological activities of chemokine (C-C motif) ligand 2 (CCL2) are mediated via C-C receptor-2 (CCR2). Increased CCL2 level is associated with metastasis many cancers. In our study, we investigated the role CCL2/CCR2 axis in development spontaneous intestinal tumorigenesis using ApcMin/+ mouse model. Ablation CCR2 mice significantly increased overall survival and reduced tumor burden. Immun...

Abstract Although GWAS have implicated chemokine receptors in affecting disease severity, the role of chemokines COVID-19 pathogenesis has not been defined. To bridge this gap, we surveyed expression 14 on blood leukocytes from 19 hospitalized patients vs. healthy controls. Among many differences between and controls, found that CCR2, which shown mediates lymphocyte transendothelial migration, ...

Chemokine receptor CCR2 mediates monocyte mobilization from the bone marrow (BM) and subsequent migration into target tissues. The degree to which CCR2 is differentially expressed in leukocyte subsets, and the contribution of CCR2 to these leukocyte mobilization from the BM are poorly understood. Using red fluorescence protein CCR2 reporter mice, we found heterogeneity in CCR2 expression among ...

Monocyte/macrophage recruitment correlates strongly with the progression of renal impairment in diabetic nephropathy (DN). C-C chemokine receptor (CCR)2 regulates monocyte/macrophage migration into injured tissues. However, the direct role of CCR2-mediated monocyte/macrophage recruitment in diabetic kidney disease remains unclear. We report that pharmacological blockade or genetic deficiency of...

Activated monocytes are present in the arterial walls of hypertensive patients and animals. Monocyte chemoattractant protein-1 (MCP-1), which controls monocyte function through its receptor (CCR2), is implicated in hypertensive inflammatory changes in the arterial wall. The role of CCR2 expression on monocytes in hypertension-induced vascular remodeling, however, has not been addressed. We hypo...

Monocyte chemoattractant protein (MCP)-1 is upregulated in atherosclerotic plaques and in the media and intima of injured arteries. CC chemokine receptor 2 (CCR2) is the only known functional receptor for MCP-1. Mice deficient in MCP-1 or CCR2 have marked reductions in atherosclerosis. This study examines the effect of CCR2 deficiency in a murine model of femoral arterial injury. Four weeks aft...

To evaluate the role of CCR2 in allergic asthma, mutant mice deficient in CCR2 (CCR2(-/-)) and intact mice were sensitized with i.p. OVA with alum on days 0 and 7, and challenged by inhalation with nebulization of either OVA or saline. Airway hyperreactivity, measured by the methacholine-provoked increase in enhanced pause, was significantly increased (p < 0.05) in OVA-challenged CCR2(-/-) muta...
