In type 1 diabetes (T1D), nearly all Î²-cells are killed by the body's own immune system, while partial Î²-cell loss in type 2 diabetes (T2D) is thought to be a product of metabolic imbalance due to insulin resistance in peripheral tissues. The reduced Î²-cell mass following the development of T1D and T2D is not restored or regenerated. Regeneration of pancreatic islet Î²-cells and restoration of Î²-cell mass would re-establish regulation of blood glucose in diabetic patients. My thesis research strives to elucidate molecular pathways of Î²-cell proliferation and regeneration to determine effective ways to replenish Î²-cell mass in patients with diabetes. My research intends to take advantage of past biological models and a recently developed pseudoislet system to genetically manipulate human islet cells, particularly Î²-cells.
