title: Anti-galectin-1 autoantibodies in serum of patients with neurological diseases.
abstract: The presence of autoantibodies to human brain galectin-1 was investigated in serum from patients with multiple sclerosis, patients with or without evidence of other neurological disorders, and healthy controls, using an ELISA on purified brain galectin-1. Levels of autoantibodies to galectin-1 were significantly higher in patients than in healthy controls. Comparison of levels of anti-galectin-1 and anti-idiotypic antibodies mimicking human brain galectin-1 (L-IgG) showed that the highest levels of autoantibodies were present in patients with low levels of L-IgG. This finding can be explained by hypothesizing that the concentration of autoantibodies to galectin-1 is possibly associated with impairment of the regulation of the immune system.
