- Abstract
Insulin-dependent diabetes mellitus (IDDM) usually begins in childhood or early adulthood, and its aetiology is thought to involve autoimmune damage to the islet cells that secrete insulin1. To investigate an additional target of autoimmunity in IDDM we examined sera for antibodies to insulin receptors. Such antibodies were defined by their ability to compete with insulin for binding to insulin receptors and by their capacity to behave like insulin in activating lipogenesis in adipocytes. We now report the occurrence of anti-insulin receptor antibodies of the IgM class in the sera of 10 of 22 IDDM patients obtained before their treatment with exogenous insulin. Furthermore, two of five IDDM patients who were initially negative developed anti-insulin receptor antibodies during treatment with human or pork insulin. These findings suggest that autoimmunity to the insulin receptor may contribute to the pathophysiology of IDDM.
