Antibodies to Glutamic Acid Decarboxylase Discriminate Major Types of Diabetes Mellitus

Antibodies to glutamic acid decarboxylase discriminate major types of diabetes mellitus.

Insulin-dependent diabetes mellitus (IDDM) is marked by circulating antibodies to a 64,000-M(r) islet cell antigen identified as glutamic acid decarboxylase (GAD). We describe a radioimmunoprecipitation assay with GAD isolated from pig brain. The sera tested were from 80 patients with IDDM including 26 with disease of recent onset and 54 with disease of longer duration (3-42 yr), 20 with non-in...

INVESTIGATION ON ANTI-GLUTAMIC ACID DECARBOXYLASE ANTIBODIES IN TYPE I DIABE TES MELLITUS

Antibodies directed against the enzyme glutamic acid decarboxylase (GAD) are believed to be the main cause of destruction of pancreatic islet cells in type I (insulin dependent) diabetes mellitus. The enzyme was found both in the brain and pancreatic beta cells. Although similarities in identity of GAD in human and rat brain have been demonstrated, little is known about the interaction betw...

Monoclonal antibodies to glutamic acid decarboxylase.

Five monoclonal antibodies that recognize chicken brain glutamic acid decarboxylase (GAD) have been selected and designated GAD-1 to -5. GAD-1 to -5 were selected on the basis of their ability to immunoprecipitate active GAD from crude brain extracts. GAD-1 recognizes an epitope that is conserved in many vertebrates; the epitope recognized by GAD-5 is restricted to the chicken. Radioimmunoassay...
