Abstract:
Of 22 rabbits sensitized with GD1b, 12 developed experimental sensory ataxic neuropathy. The affected rabbits had a higher level of serum IgG monospecific to GD1b than the unaffected ones. The GD1b-positive neuronal cytoplasms of rabbit dorsal root ganglia had larger diameters than the negative ones. IgG antibody monospecific to GD1b may preferentially bind to large primary sensory neurons, causing sensory ataxic neuropathy.
