Pancreatic Islet Dysfunction in Diabetes

Pancreatic islet dysfunction is a hallmark of both type 1 and type 2 diabetes, characterized by the impaired secretion of insulin from beta cells. In type 1 diabetes, autoimmune destruction leads to complete insulin deficiency, while in type 2 diabetes, beta cells often fail to compensate for insulin resistance. This dysfunction results in hyperglycemia and contributes to various metabolic complications. Research is ongoing to explore potential therapies, including beta-cell regeneration and transplantation, to restore normal insulin production in affected individuals.
