Islet cell antigens in the prediction and prevention of insulin-dependent diabetes mellitus.

Insulin-dependent diabetes mellitus (IDDM) is associated with both antibody and T-cell autoimmunity to pancreatic islet cell components. In recent years, considerable progress has been made in the identification of the molecular components of the pancreatic islets to which these immune responses are directed. These advances have led to the development of a number of immune markers for use in screening for individuals at risk for disease, and there is promise of antigen-specific immune intervention therapies to prevent diabetes in those identified as at risk. In this article, we review our current knowledge of autoantigens associated with IDDM and the implications this has on the prediction and prevention of the disease.
