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 immunoperoxidase 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.
