Clinical trials: Insulin Secretion
Healthy
A Dose-response Study Examining the Contribution of GLP-1 Receptor Signaling to Glucagon-stimulated Insulin Secretion
The GLP-1 receptor (GLP1R) gene is found on the beta cells of the pancreas. Its role is in the control of blood sugar level by enhancing insulin secretion from the pancreas after eating a meal.
