Abstract
An increase in immunoreactivity associated with a 58-kDa antigen was found in a majority of MS cerebellar homogenates examined by Western blot analysis using antisera obtained by selective immunization of rabbits with autopsy cerebella. Two-dimensional immunoblotting demonstrated that the majority of the increased immunoreactivity observed in MS cerebella was associated with the highest apparent pI of three immunoreactive species at 58 kDa. Immuno-crossreaction with rat cerebellar homogenates demonstrated that the 58-kDa antigen was developmentally regulated, showing the greatest immunoreactivity at embryonic day 15. The 58-kDa cerebellar antigen may represent a membrane protein which is re-expressed as part of the onset of MS.
