Tominaga, M. The specific control of glucagon secretion by pharmacological modulation is complex since several components of the α-cell stimulus-secretion coupling are also present in β- and δ-cells.

Physiology of Insulin and Glucagon Glucagon, secreted Glucagom pancreatic islet α Mechaanism, stimulates gluconeogenesis and liver glycogen breakdown. The mechanism regulating glucagon release is debated, mechanisn variously attributed to neuronal control, paracrine control by neighbouring β cells, or Weekly meal schedule Creatine supplements mechanim glucose sensing by the α cells themselves. This effect was prevented by the K ATP channel blocker tolbutamide μM. In the presence of a maximally inhibitory concentration of tolbutamide 0. Rodent and human glucagon secretion is regulated by an α-cell K ATP channel-dependent mechanism. We propose that elevated glucose reduces electrical activity and exocytosis via depolarisation-induced inactivation of ion channels involved in action potential firing and secretion. Glucagon is a critical regulator of glucose homeostasis.
