Insulin secretion from pancreas

NettetProduction, which is otherwise freerunning, is suppressed/regulated by amylin, a peptide hormone co-secreted with insulin from the pancreatic β cells. As plasma glucose levels recede, the subsequent reduction in amylin secretion alleviates its suppression of the α cells, allowing for glucagon secretion. Secretion of glucagon is stimulated by: Nettet27. des. 2024 · Indeed, a study using the perfused rat pancreas model showed that glucose-induced insulin secretion is not affected by signals from neighboring α-cells . In the human islet, by contrast, the percentage of α-cells is higher, α-cells and β-cells are aligned randomly along blood vessels, and most β-cells face α-cells (>70%) ( 4 ), …
