Monocyte chemoattractant protein 1 (MCP-1) is a CC cytokine that fundamentally contributes to the pathogenesis of inflammatory renal disease. MCP-1 is highly expressed in cytokine-stimulated mesangial cells in vitro and following glomerular injury in vivo. Interventions to limit MCP-1 expression are commonly effective in assorted experimental models. Fish oil, an abundant source of n-3 fatty ac...

AIM Monocyte chemoattractant protein-1 (MCP-1) is a potent chemokine and plays an important role in atherosclerosis of Type 2 diabetes. The aim of this study was to investigate the methylation status of CpG sites in the MCP-1 promoter in Type 2 diabetic patients and its correlation to serum MCP- 1 level, and blood glucose level. METHODS The 32 patients with Type 2 diabetes and 15 healthy cont...

BACKGROUND Monocyte infiltration into the arterial wall and its activation is the central event in atherogenesis. Thus, monocyte chemoattractant protein-1 (MCP-1) might be a novel therapeutic target against atherogenesis. We and others recently reported that blockade or abrogation of the MCP-1 pathway attenuates the initiation of atheroma formation in hypercholesterolemic mice. It remains uncle...

Monocyte chemoattractant protein-1 (MCP-1, also known as CCL2) secreted by adipocytes is a member of the CC chemokine family and plays a pivotal role in the inflammatory process. A polymorphism, the -2518 A/G of MCP-1 gene, has been associated with type 2 diabetes, type 1 diabetes, parameters of insulin resistance and obesity. Therefore, we investigated the effects of MCP-1 single nucleotide po...

OBJECTIVE To evaluate direct versus indirect monocyte chemoattractant protein (MCP)-1/CCR2 signaling and to identify the cellular producers and effectors for MCP-1 during neointimal hyperplasia (NIH) development in vein grafts. METHODS AND RESULTS Genomic analysis revealed an overrepresentation of 13 inflammatory pathways in wild-type vein grafts compared with CCR2 knockout vein grafts. Furth...

STUDY OBJECTIVE Several lung diseases are characterized by the presence of increased numbers of activated macrophages. The recruitment and activation of peripheral blood monocytes are potentially critical regulatory events for the control of pulmonary inflammation. The chemokine monocyte chemoattractant protein (MCP)-1 is a potent chemoattractant for monocytes. MCP-1 is produced by lung epithel...

BACKGROUND Glomerular crescents play an important role in progressive glomerular injury. The lesions consist of epithelial cells, macrophages and deposits of fibrin and extracellular matrix. Monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein-2 (MIP-2) are members of chemokine subfamilies. MCP-1 and MIP-2 are potent chemoattractant leukocyte cytokines, and they may be...

BACKGROUND Upregulation of local monocyte chemoattractant protein-1 (MCP-1) production is involved in glomerular damage through macrophage recruitment and activation in diabetic nephropathy. Treatment of db/db mice with soluble receptor for advanced glycation end-products (RAGE) prevented recruitment of macrophages to the glomeruli and reduced albuminuria, suggesting that binding of ligands and...

Interstitial fluid is constantly drained into lymph nodes (LNs) via afferent lymph vessels. This conduit enables monocyte-derived macrophages and dendritic cells to access LNs from peripheral tissues. We show that during inflammation in the skin, a second recruitment pathway is evoked that recruits large numbers of blood-borne monocytes to LNs via high endothelial venules (HEVs). Inhibition of ...

In primary human diploid fibroblasts, infection with an unpurified stock of human cytomegalovirus induced accumulation of the CC chemokine MCP-1 in the cell culture medium. By 24 h postinfection, the level of MCP-1 returned to that in uninfected cultures. When cells were infected with UV-inactivated human cytomegalovirus, the induction of MCP-1 was still observed, but no reduction was seen by 2...
