Abstract:
The potential therapeutic applications of glucagon-like peptide-1 (GLP-1) have led to the development of GLP-1 receptor agonists (GLP-1RAs), which replicate GLP-1's effects. The primary use of GLP-1RAs is the management of type 2 diabetes (T2DM) by stimulation of insulin secretion. In addition to its metabolic functions, GLP-1 exhibits significant anti-inflammatory effects through various molecular pathways, utilizing both direct and indirect mechanisms. Experimental studies have revealed that GLP-1RAs modulate multiple inflammatory pathways, including cytokine production, oxidative stress, glucotoxicity, lipotoxicity, and immune cell recruitment across multiple organs. They interact with their receptors on immune cells, thereby reducing the production of inflammatory cytokines and decreasing the infiltration of immune cells into tissues. There is considerable overlap among the pathways activated by GLP-1R in cardiovascular tissue, which can lead to anti-apoptotic, antioxidative, and anti-inflammatory effects. Clinical studies have confirmed the anti-inflammatory effects of GLP-1RAs in conditions such as acute myocardial infarction, left ventricular dysfunction, coronary artery disease, and ST-segment elevation myocardial infarction. Notably, GLP-1RAs are included in the European Society of Cardiology guidelines for managing cardiovascular disease in patients with T2DM.
