mice exacerbated atherosclerosis. Whole-genome expression profiling discovered that CX3CL1 chemokine was the most upregulated gene in the insulin-stimulated arterial endothelial cells. Specific deletion of a CX3CL1 receptor, Cx3cr1 gene, in monocytes/macrophages completely abrogated the APM-exacerba...
