2D immunomic approach for the study of IgG autoantibodies in the experimental model of multiple sclerosis.

Abstract:

:2D-immunomics may be useful in the identification of autoantigens in neurological autoimmune diseases, but its application may be limited by denaturation of target proteins. Here we compared the capacity of a single or multiple antigens to elicit autoantibodies targeting multiple neural autoantigens by ELISA and 2D-immunomics. We induced experimental autoimmune encephalomyelitis (EAE) with MBP peptide(89-104), total MBP or spinal cord homogenate. Both techniques showed anti-MBP IgG only after immunization with total MBP. In addition, 2D-immunomics revealed the presence in EAE mice of autoantibodies targeting other neural proteins, some displaying partial sequence homology with MBP. The present finding by 2D-immunomics of multiple neural proteins targeted by autoantibodies generated by a single antigen may help to explain the complex autoimmune response observed in multiple sclerosis.
