Tachyphylaxis glucagon
WebSep 25, 2004 · Glucagon increases cardiac contractility through Gs protein-coupled glucagon receptors, but the inotropic responses fade. The fade could be due to receptor desensitisation or to the action of phosphodiesterases (PDE), or to both mechanisms. We investigated the effects of the PDE4 inhibitor rolipram (1 μM) on the inotropic and cAMP … WebBackground: Glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1RAs) are promising weight-loss drugs, but real-world data concerning the liability of GLP-1RAs in gastrointestinal safety are lacking.
