The membrane attack complex (MAC) assembles from C5b-9 complement components and has neoantigenic properties. Antihuman-MAC rabbit immunserum was applied in order to localize the MAC in myasthenic muscles. Using the indirect immuneperoxidase method MAC was demonstrated at the motor end-plates in eleven myasthenic patients who underwent thymectomy. This result provides direct evidence of antibody-dependent complement-mediated injury of acetylcholine receptors in myasthenia gravis.
