Response of peripheral-blood mononuclear cells to glutamate decarboxylase in insulin-dependent diabetes.
Insulin-dependent diabetes is characterised by autoantibodies to several pancreatic-islet-cell antigens, including glutamate decarboxylase. We measured the proliferative responses to this antigen of peripheral-blood mononuclear cells from patients with newly diagnosed insulin-dependent diabetes, relatives of diabetic patients, and healthy controls. The likelihood of a positive response was substantially greater among the diabetic patients and relatives positive for islet-cell autoantibodies (ICA) than among subjects at low risk of diabetes (controls and ICA-negative relatives). Glutamate decarboxylase may have a pathogenetic role in insulin-dependent diabetes.
