“…The evidence includes intrathecal Ig synthesis (Kabat and Freedman, 1950), the presence of oligoclonal IgG bands in the CSF (Johnson et al, 1977;Lowenthal et al, 1960), identification of plasma cells and Ig in MS lesions and Ig deposition at the border of actively demyelinating plaques (Esiri, 1977;Lumsden, 1971;Storch et al, 1998;Woyciechowska and Brzosko, 1977). Several studies have sought to identify the antigenic targets of the B cells and antibodies found in CSF and brain plaques in MS, yet no single target has been found which is directly responsible for the development or progression of MS. Several of the targets identified thus far are of interest to our study.…”
