Autoantibodies against aromatic L-amino acid decarboxylase in autoimmune polyendocrine syndrome type I.
Patients with autoimmune polyendocrine syndrome type I (APS I) have autoantibodies against the enzyme aromatic L-amino acid decarboxylase (AADC) of pancreatic beta-cells. The aim of the present study was to investigate the presence of anti-AADC antibodies in a large cohort of patients with APS I, and in patients with isolated insulin-dependent diabetes mellitus (IDDM). We found autoantibodies a...
متن کاملAutoantibodies to human tryptophan hydroxylase and aromatic L-amino acid decarboxylase.
OBJECTIVE To assess the prevalence of autoantibodies (Abs) to tryptophan hydroxylase (TPH) and aromatic l-amino acid decarboxylase (AADC) in patients with different autoimmune diseases and to analyse their respective epitopes. DESIGN TPH and AADC Abs were measured in an immunoprecipitation assay using (35)S-labelled full-length and fragments of TPH and AADC. METHODS Patients with different ...
متن کاملAromatic L-amino acid decarboxylase deficiency: diagnostic methodology.
Aromatic L-amino acid decarboxylase (EC. 4.1.1.28) deficiency is a newly described inborn error of metabolism that affects serotonin and dopamine biosynthesis. The major biochemical markers for this disease are increases of L-dopa, 3-methoxytyrosine, and 5-hydroxytryptophan in urine, plasma, and cerebrospinal fluid together with decreased cerebrospinal fluid concentrations of homovanillic acid ...
متن کاملGene therapy for aromatic L-amino acid decarboxylase deficiency.
Aromatic L-amino acid decarboxylase (AADC) is required for the synthesis of the neurotransmitters dopamine and serotonin. Children with defects in the AADC gene show compromised development, particularly in motor function. Drug therapy has only marginal effects on some of the symptoms and does not change early childhood mortality. Here, we performed adeno-associated viral vector-mediated gene t...
متن کاملPurification of aromatic L-amino acid decarboxylase from bovine brain with a monoclonal antibody.
Aromatic L-amino acid decarboxylase was purified from bovine brain for the first time by affinity chromatography using a monoclonal antibody to the enzyme, and it was compared with the decarboxylase purified from bovine adrenal medulla by the same procedure. The monoclonal antibody was produced from a hybridoma established for the enzyme highly purified from bovine adrenal medulla. The Mr value...
