β-cell function refers to the process by which insulin-secreting pancreatic β-cells regulate blood glucose levels in the body. These cells play a crucial role in maintaining glucose homeostasis by releasing insulin in response to elevated blood sugar levels, such as after a meal. Dysfunctions in β-cell function can lead to a variety of metabolic disorders, including type 2 diabetes. Research in this area focuses on understanding the molecular mechanisms underlying β-cell function, identifying factors that influence insulin secretion, and developing potential therapies for improving β-cell health and function. By studying β-cell function, researchers aim to better understand the pathophysiology of diabetes and discover new strategies for its prevention and treatment.
