Low affinity anti-GM 1 IgM-antibodies are part of the normal repertoire of human plasma antibodies (Mizutamari et al.: J Neuroimmunol 50:215-220, 1994), a fact that is against the pathological role proposed for them in autoimmune diseases. Here we present evidence that these low affinity IgM-antibod
Fifty-nine percent of 49 patients with motor neuron disease and 25% of 91 control subjects had IgM antibodies to ganglioside GM1 but usually not to GDlb at titers less than 1:80. This suggests that antibodies to GM1 may be part of the normal human antibody repertoire. However, given the higher incid
I n a patient with motor neuron disease and benign IgMk monoclonal gammopathy, the M protein reacted with the glycolipids GM1, GDlb, and asialo GM1 and, by immunoblot, with some high-molecular-weight neural-specific glycoproteins. T h e main reactive bands had an approximate molecular weight of 250
