title: Serum antibodies against central nervous system proteins in human demyelinating disease.
abstract: An immunoblotting technique has been used to screen serum samples from patients with demyelinating disease for antibody directed against central nervous system proteins. Antibodies of the IgM, IgG and IgA class directed against one or more of the particulate fraction proteins tubulin, myelin basic protein, 69 K neurofilament protein, glial fibrillary acidic protein, myelin associated glycoprotein or Wolfgram protein were present in 94, 54 and 47%, respectively, of multiple sclerosis sera examined. IgM antibodies against tubulin and myelin basic protein predominated. A similar antibody spectrum was seen in a significant proportion of sera from patients with optic neuritis, subacute sclerosing panencephalitis and motor neurone disease, in which primary or secondary demyelination occurs. Antibodies of all three classes directed against the 169 K and 220 K neurofilament proteins and against some unidentified proteins of human peripheral nerve, kidney, liver, spleen and skeletal muscle were detected in sera from healthy subjects and patients with neurological disease.
