Glucagon-Like Peptide-1, an incretin hormone that regulates blood sugar, slows gastric emptying, and reduces appetite, targeted by semaglutide and tirzepatide.
Glucagon-Like Peptide-1 (GLP-1) is a 30-amino acid incretin hormone secreted by L-cells in the intestinal epithelium in response to nutrient ingestion. It exerts its metabolic effects by binding to the GLP-1 receptor, a G-protein-coupled receptor expressed on pancreatic beta cells, the central nervous system, heart, kidney, and gastrointestinal tract. GLP-1's primary actions include stimulating glucose-dependent insulin secretion, suppressing glucagon release, slowing gastric emptying, and signalling satiety to the brain via vagal afferents and direct hypothalamic action. Native GLP-1 has a very short half-life of approximately 2 minutes due to rapid degradation by dipeptidyl peptidase-4 (DPP-4), which led to the development of long-acting GLP-1 receptor agonists such as semaglutide and the dual GIP/GLP-1 agonist tirzepatide. These synthetic analogues have transformed metabolic research through sustained receptor activation.
