Islet cell autoantibodies comprise autoantibodies to islet cell cytoplasm (ICAs); to native insulin, referred to as insulin autoantibodies (IAAs) (208); to glutamic acid decarboxylase ([GAD.sub.65]A) (209-211); and to two tyrosine phosphatases [insulinoma-associated antigens IA-2A (212) and IA-2[beta]A (213)].

Insulin autoantibodies are common in patients receiving exogenous insulin, but they can also be observed in individuals never treated with insulin, particularly in patients with autoimmune diseases [up to 30% (2)].
