Bidirectional Pharmacology of GIP Receptor Targeting in Obesity: Historical Foundations, Mechanistic Divergence, and Translational Boundaries.
The glucose-dependent insulinotropic polypeptide receptor (GIPR) has emerged as a central target in next-generation anti-obesity drug development. Its pharmacology, however, presents an apparent paradox: sustained GIPR agonism and GIPR antagonism can both lower body weight, and both can augment weight loss produced by...
