Antibodies to 125I-glutamic acid decarboxylase in patients with stiff man syndrome.
Antibodies to glutamic acid decarboxylase (GAD) are found in about 40% of patients with stiff man syndrome. A new assay involving immunoprecipitation of (125)I-glutamic acid decarboxylase was used to measure anti-GAD antibodies in 18 patients with stiff man syndrome. Of the eight serum samples from patients with stiff man syndrome, that had previously been found positive by immunoprecipitation ...
متن کاملA case of stiff dog syndrome associated with anti-glutamic acid decarboxylase antibodies
BACKGROUND The stiff person syndrome (SPS) is a rare and debilitating autoimmune disorder with an unknown pathogenesis and variable clinical presentation that can present a diagnostic challenge. Although entities that clinically mimic stiff-person spectrum disorders (SPSD) have manifested in horses, they have not been reported in dogs. CASE PRESENTATION We describe a 2-year-old beagle dog pre...
متن کاملMonoclonal 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...
متن کاملINVESTIGATION 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...
متن کاملIdentification of a dominant epitope of glutamic acid decarboxylase (GAD-65) recognized by autoantibodies in stiff-man syndrome
Glutamic acid decarboxylase (GAD) is the enzyme that synthesizes the neurotransmitter gamma-aminobutyric acid (GABA) in neurons and in pancreatic beta cells. It is a major target of autoimmunity in Stiff-Man syndrome (SMS), a rare neurological disease, and in insulin-dependent diabetes mellitus. The two GAD isoforms, GAD-65 and GAD-67, are the products of two different genes. GAD-67 and GAD-65 ...
