CCL2 and type 2 diabetes mellitus: MCP‐1 is a small cytokine and an effective chemoattractant for circulating monocytes; its plasma levels are increased in T2DM patients (Piemonti et al. 2009), and its protein expression is elevated in lipotoxic cardiomyocytes, as evidenced by its high protein expression in PA‐induced lipotoxic HL‐1 cardiomyocytes (Ren et al. 2024).
