Currently, there are other dual GIPR/GLP-1R agonists available, such as GLP-1R/GR (glucagon receptor), GLP-1R/AR (amylin receptor), and GLP-1R/NPYR (peptide YY binds to neuropeptide Y receptors) [36, 115] and even triple agonists that can activate GIPR to treat obesity and T2DM. The gene discussed is GCGR; the disease is obesity disorder.
