The receptor
The GLP-1 receptor is a class B G-protein-coupled receptor, coupling primarily to Gs and raising intracellular cyclic AMP. It is expressed in pancreatic islets and at lower levels in several other tissues including the central nervous system.
Why it attracted attention
Native GLP-1 is degraded within minutes by DPP-4, which made it impractical as a starting point until analogues resistant to that degradation were developed. Research since has examined glucose-dependent insulin secretion, gastric emptying, and central pathways involved in appetite regulation.
In multi-agonist research
GLP-1 is one arm of the dual and triple agonists now studied. Combining it with GIP or glucagon activity is an attempt to engage complementary pathways with a single molecule, and the research question is how those arms interact rather than what each does alone.
