Abstract

IgM lambda monoclonal antibodies in two patients with motor neuron disease showed the same unique antigenic specificity. They bound to gangliosides GM1 and GD1b and to lacto-N-tetraose-BSA. By immunofluorescence microscopy they bound to central and peripheral nerve tissue and to motor end-plates at the neuromuscular junction. Sera from control subjects did not contain antibodies of similar specificity. Monoclonal IgMs with the same unique specificity could be responsible for motor neuron disease in some patients with monoclonal gammopathies.
