Abstract:
Glucagon-like peptide-1 (GLP-1) analogs are considered the best current medicines for type 2 diabetes (T2D) and obesity due to their actions in lowering blood glucose and body weight. Despite similarities to GLP-1, glucose-dependent insulinotropic polypeptide (GIP) has not been extensively pursued as a medical treatment for T2D. This is largely based on observations of diminished responses of GIP to lower blood glucose in select patients, as well as evidence from rodent knockout models implying that GIP promotes obesity. These findings have prompted the belief in some, that inhibiting GIP action might be beneficial for metabolic diseases. However, a growing body of new evidence - including data based on refined genetically modified models and improved pharmacological agents - suggests a paradigm shift on how the GIP system should be manipulated for metabolic benefits.

GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
