Single Nucleotide Polymorphisms in Monocyte Chemoattractant Protein-1 and Its Receptor Act Synergistically to Increase the Risk of Carotid Atherosclerosis

摘要

BackgroundMonocyte chemoattractant protein 1 (MCP-1), acting in concert with its receptor chemokine receptor 2 (CCR2), promotes recruitment of macrophages into atherosclerotic plaque. We examined whether single nucleotide polymorphism (SNP) variants in the MCP-1 or CCR2 genes independently or in combination are associated with carotid artery atherosclerosis in an African American population at increased risk of vascular disease.
