Immunology of myasthenia gravis
1983
Anti-acetylcholine-receptor antibody is demonstrable in more than 90 per cent of patients with myasthenia gravis. Serum antibody titers do not show a direct correlation with disease severity, although in certain patients antibody levels increase in association with disease activity. Impairment of neuromuscular transmission results from the loss of junctional receptors, either as a result of receptor internalization or destruction of junctional folds containing the acetylcholine receptor. Myasthenia gravis manifests immunologic, genetic, and clinical similarities to rheumatic syndromes, suggesting a generic immune dysfunction common to these disorders.
