The Diabetes: Treatment, Prevention, and Complications Program supports both basic and clinical studies aimed at addressing the prevention, treatment and pathophysiology of type 1 and type 2 diabetes. Studies on drug development or testing of medical therapies to treat type 1 and type 2 diabetes are included in this program. Studies specific to type 1 diabetes (T1DM) include those examining the cellular or immunological therapies to induce tolerance or arrest conversion from normal glucose homeostasis or dysglycemia to T1DM. Studies more specific to type 2 diabetes (T2DM) include those examining medical or surgical approaches that prevent diabetes, induce diabetes remission or improve dysglycemia. Studies relevant to both types of diabetes include those proposing lifestyle (diet and exercise) and other behavioral interventions to prevent or treat diabetes, such as approaches to improving health-related behaviors and enhancing diabetes self-management and other aspects of diabetes care. This Program encompasses basic, clinical and translational research on the pathophysiology and treatment of diabetic complications that apply to multiple tissues and organ systems. It includes tissue-specific research on diabetic wound healing, diabetic neuropathy, and central nervous system impairments including cognition, brain structure and function, resulting from dysglycemia. The program also includes research on diabetes complications such as hypoglycemia and diabetic ketoacidosis.
