Cyclic adenosine monophosphate critically modulates cardiac GLP-1 receptor's anti-inflammatory effects.

Background: Glucagon-like peptide (GLP)-1 receptor (GLP1R) agonists exert a multitude of beneficial cardiovascular effects beyond control of blood glucose levels and obesity reduction. They also have anti-inflammatory actions through both central and peripheral mechanisms. GLP1R is a G protein-coupled receptor (GPCR), coupling to adenylyl cyclase (AC)-stimulatory Gs proteins to raise cyclic 3`-5`-adenosine monophosphate (cAMP) levels in cells.
