CCL2 (Monocyte Chemoattractant Protein, called also MCP-1) is another well-known cytokine in cardiology that is strictly related to several cardiovascular events such as atherosclerosis, myocardial injury, hypertension, angiotensin-2 homeostasis (through functional interaction with an angiotensin2 type 1 receptor) [126], and other diseases. Here, CCL2 is linked to hypertensive disorder.
