title: Antibody to sialosyllactosaminylparagloboside in a patient with IgM paraproteinemia and polyradiculoneuropathy.
abstract: Serum from a patient with IgM paraproteinemia and polyradiculoneuropathy, diagnosed as malignant lymphoma, reacted specifically with a ganglioside, sialosyllactosaminylparagloboside (SLPG), in human peripheral nerve but not with myelin-associated glycoprotein (MAG). This finding demonstrates the existence of anti-SLPG antibody in the patient's serum, suggesting that this antibody may play a role in the pathogenesis of neuropathy.
