CCL2 and atherosclerosis: Nuclear factor-kappa B (NF-κB), as an inflammatory hub, is a crucial transcription factor of numerous genes involved in the progression of atherosclerosis, e.g., IL-1α, IL-6, IL-8, GM-CSF [63], TNF-κ [64], IL-1β [65], platelet-activating factor [66], bacterial superantigen [67], taxol [68], IFNγ and lipopolysaccharide [69], as well as MCP-1/CCL-2 [70], and macrophage inflammatory protein 1-α (MIP1α)/CCL-3 [71].
