Triple Receptor Agonism: GLP-1/GIP/GCGR Mechanism
Source: PubMed PMID: 36070752
Summary: This study characterized GLP-3 as a single-molecule triple agonist in receptor binding and cell-based signaling assays, demonstrating simultaneous engagement of GLP-1R, GIPR, and glucagon receptor with distinct potency ratios. Preclinical work characterized concurrent engagement of all three receptor systems across receptor-binding and signaling assays.
Glucagon receptor signaling characterization
Source: PubMed PMID: 25365075
Summary: This review summarized glucagon receptor (GCGR) pharmacology and signaling characterization relevant to multi-receptor agonist research, including receptor-coupled assay systems and pathway profiling in preclinical models.
