Islet function refers to the biochemical and physiological processes that occur within pancreatic islets, which are clusters of cells in the pancreas responsible for producing and releasing hormones such as insulin and glucagon. These hormones play a crucial role in regulating blood sugar levels and metabolism. Research in islet function involves studying how these cells communicate with each other, respond to changes in blood glucose levels, and regulate hormone secretion. It also examines how dysfunction in islet cells can lead to diseases such as diabetes. Overall, understanding islet function is important for developing new treatments and interventions for diabetes and other metabolic disorders.
