Pancreatic beta cells are a type of cell found in the pancreas that are responsible for producing and secreting insulin, the hormone that regulates blood sugar levels. These cells are vital for maintaining normal glucose homeostasis in the body, as they respond to changes in blood sugar levels by releasing insulin to help cells take up and store glucose for energy. Research on pancreatic beta cells focuses on understanding their function, regulation, and dysfunction in diseases such as diabetes. Scientists study how beta cells develop, how they sense and respond to glucose, and how they can be protected or regenerated to improve insulin secretion in diabetes. This research area is critical for developing new therapies for diabetes and related metabolic disorders.
