MCP chemokines can stimulate CCR2, which is located on monocytes and macrophages and is associated with the pathogenesis of atherosclerosis and type 2 DM [24, 25]. Both exogenous and endogenous CCL7 can recruit leukocytes that express associated receptors to migrate along the concentration gradient to the sites of inflammation. The gene discussed is CCL7; the disease is atherosclerosis.
