Abstract

We examined the reactivity of a panel of anti-GM<sub>1</sub> immunoglobulin M monoclonal antibodies (MAbs) cloned from multifocal motor neuropathy patients with lipopolysaccharides (LPSs) of <i>Campylobacter jejuni</i> strains, including serotype O:41 strains associated with Guillain-Barré syndrome. The MAbs reacted with ganglioside GM<sub>1</sub> to different degrees, and these differences in fine specificities for GM<sub>1</sub> were reflected in the different degrees of reactivity with each of the <i>C. jejuni</i> LPSs tested. Antibodies could also be discriminated by the varying patterns of inhibition by cholera toxin (a GM<sub>1</sub> ligand) in LPS binding studies. These results indicate that there is a substantial heterogeneity among <i>C. jejuni</i> O:41 strains in their expression of GM<sub>1</sub>-like epitopes and among the fine specificities of different neuropathy-associated anti-GM<sub>1</sub> antibodies.
