Islet Biology/Insulin Secretion

Islet Biology/Insulin Secretion

Islet biology and insulin secretion are central to understanding the pathophysiology of diabetes and developing targeted therapeutic interventions. Islets of Langerhans, clusters of endocrine cells within the pancreas, play a crucial role in glucose homeostasis by secreting hormones such as insulin and glucagon. Beta cells, the predominant cell type within the islets, are responsible for insulin secretion in response to elevated blood glucose levels.

The intricate biology of islets involves complex cellular interactions and signaling pathways that regulate insulin secretion. Glucose sensing by beta cells triggers a series of events, including depolarization of the cell membrane, influx of calcium ions, and exocytosis of insulin-containing vesicles. Disruptions in these processes can lead to impaired insulin secretion and contribute to the development of diabetes.

Understanding the nuances of islet biology and insulin secretion holds promise for developing novel therapies for diabetes, including beta cell replacement strategies and pharmacological agents that enhance insulin secretion or protect beta cell function. The Islet Biology/Insulin Secretion session at the Diabetes 2024 summit will delve into these topics, showcasing the latest research and innovations in this field.
