Immunological studies of the pathogenesis of multiple sclerosis. Cell-mediated cytotoxicity by peripheral blood lymphocytes against basic protein of myelin, encephalitogenic peptide, cerebrosides and gangliosides.
Cell-mediated cytotoxic reactions against myelin basic protein (MBP), encephalitogenic peptide, cerebrosides and gangliosides were studied in 165 MS cases. The cytotoxicity, which is detectable only in the autologous system, is mediated by T lymphocytes bearing antigens reactive with antibody OKT8. The cytotoxicity is highest during active MS regardless of whether it is relapsing or chronic progressive. During inactive MS cytotoxicity is significantly less and remains virtually unchanged at a low level over long periods. The degree of cytotoxicity is thus, predominantly, dependent on the activity stage of the disease. Further, there is a correlation with the severity of the clinical deficiencies. The pathogenetic significance of cytotoxic reactions can be recognized by the close correlation between the stage and course of MS, which can be demonstrated both statistically and individually.
