Abstract
A series of monoclonal IgM anti-GM1 ganglioside antibodies has been cloned from peripheral blood lymphocytes of patients with multifocal motor neuropathy and Guillain-Barré syndrome. In solid-phase immunoassay, the antibodies react with GM1, and also in differing degrees to the structurally related glycolipids asialo-GM1 (GA1) and GD1b. Here we describe the binding patterns of six human anti-GM1 antibodies to epitopes within the human nervous system. Antibodies were observed to bind to motor neurons and spinal grey matter, dorsal and ventral spinal roots, dorsal root ganglion neurons, nodes of Ranvier, neuromuscular junctions and skeletal muscle. The distribution of immunoreactive epitopes, which included sensory structures, extended beyond those sites conventionally regarded as pathologically affected in anti-GM1 antibody-associated motor nerve syndromes. This undermines a model of disease pathogenesis based solely on antigen distribution. Factors other than the presence or absence of antigen, such as the local ganglioside topography, antibody penetration into, and pathophysiological vulnerability of a particular site may also influence the clinicopathological outcome of anti-GM1 antibody-mediated autoimmune attack.
