In type 1 diabetes, autoimmune destruction targets which pancreatic cells?

Explanation:
The main idea is that type 1 diabetes is an autoimmune attack targeting insulin-producing cells. Specifically, pancreatic beta cells in the islets of Langerhans are destroyed by autoimmune processes, mainly T-cell–mediated, leading to little or no insulin production. Without insulin, glucose can’t enter most cells effectively, causing hyperglycemia and the need for insulin therapy. Other pancreatic cells, like alpha cells that produce glucagon, aren’t the primary targets in this condition, and liver or fat cells aren’t the focus of the autoimmune destruction in classic type 1 diabetes.
