K. Lauer The Intrathecal Immune Response in Multiple Sclerosisz a Different Concept of ‘Specificity’ Vol.31 No. 4 1990 pp 245-251

The Abstract rem% as folbws : A hypothesis is presented in which the immune response in multiple sclerosis is conceived as a primary response to an autoantigen located within the immune system (e.g. a certain allotype or HLA epitope) which shows subsequent or simultaneous specificity for a greater number of nominal antigens. The increased tendency of such antibodies to self-aggregation might play a critical role in pathogenesis.
