Type 1 diabetes is an autoimmune disease that is characterized by the immune system attacking self-antigens. There is a failure or breakdown in immunological tolerance to allow this to happen. Prolonged physical or emotional stress can activate the hypothalamus-pituitary-adrenal (HPA) axis to induce production of the stress hormone glucocorticoid, causing abrupt thymus involution and result in escape of autoreactive T- cells. Though regulatory T-cells (Treg) are present in the circulation, they are unable to suppress the autoreative T-cells from initiating the destruction of ?-cells and the subsequent development of Type 1 diabetes. Stress also causes metabolic disturbances, including altered hepatic glucose metabolism, increased peripheral insulin resistance and hyperglycemia. Glucocorticoid is the potential contributor to the chronic hyperglycemia that...
