Monocyte chemoattractant protein-1 (MCP-1) is a potent chemokine that plays an important role in the recruitment of macrophages. Although previous studies have demonstrated the importance of MCP-1 in the pathogenesis of diabetic nephropathy (DN) in terms of inflammation, the role of MCP-1 and its receptor (C-C chemokine receptor 2; CCR2) in extracellular matrix (ECM) accumulation under diabetic...

OBJECTIVE The dynamic expressions of monocyte chemo attractant protein-1 (MCP-1) and CC chamomile receptor 2 (CCR2) after balloon injury and their effects in intimal proliferation were discussed. In this study, the expression of MCP-1 and its receptor during the intimal proliferation in rat artery after balloon injury were studied. METHODS Using the model of balloon injury of rats' arteries, ...

Although monocyte chemotactic protein-1 (MCP-1) is best known for its ability to recruit mononuclear cells, few studies have examined the effects of this chemokine on other events in the vascular response to injury. The purpose of the present study was to determine the influence of MCP-1 on human vascular smooth muscle (VSMC) proliferation. MCP-1 induced concentration-dependent VSMC proliferati...

BACKGROUND AND PURPOSE It is well documented that oxidized low-density lipoproteins (LDLs) can stimulate human vascular endothelial cells to produce monocyte chemoattractant protein-1 (MCP-1). Vitamin C is known to be an important antioxidant for vasodilatation. The purpose of this study was to determine whether pretreatment with vitamin C could protect against oxidized-LDL-induced expression o...

Three bunches of unripe ‘Williams’ banana fruit of different maturity, 173, 156 and 71 days from bunch emergence, were harvested. Fruit from the top, bottom and middle hands from each bunch were fumigated for 24 h with 1-methylcyclopropene (1-MCP) at 0, 5, 50 or 500 nl l at 20C. All fruit were then stored at 20C in air containing 0.1 ml l ethylene and the time taken for each fruit to ripen (gre...

BACKGROUND Phyllostachys edulis Carriere (Poaceae) is a bamboo species that is part of the traditional Chinese medicine pharmacopoeia. Compounds and extracts from this species have shown potential applications towards several diseases. One of many complications found in obesity and diabetes is the link between elevated circulatory free fatty acids (FFAs) and chronic inflammation. This study aim...

The role of monocyte chemoattractant protein-1 (MCP-1) in the recruitment of blood-derived monocytes in a model of zymosan peritoneal inflammation was investigated. After zymosan injection (1 mg) a rapid influx of polymorphonuclear leukocytes (PMN) and monocytes into the peritoneal cavity associated with mouse MCP-1 (JE) gene activation and protein secretion in the exudates occurred. MCP-1 prod...

Infection by human T-cell leukemia virus type (HTLV) I leads to adult T-cell leukemia and is also associated with the neurodegenerative disease HTLV-I-associated myelopathy/tropical spastic paraparesis. Leukocytes are attracted to sites of inflammation by chemokines. One such chemokine is monocyte chemoattractant protein (MCP)-1, a member of the C-C subfamily of chemokines. We investigated whet...
