title: [The pathogenesis of multiple sclerosis. Cytotoxic antibodies against myelin sheath tissue in multiple sclerosis].
abstract: Cytotoxic antibodies to myelin can be demonstrated by the method of 51Cr-release from chick erythrocytes coated with myelin basic protein. The cytotoxic antibody is inactivated by heating to 56 degrees C and needs complement in order to exert its action. The antibody was determined as IgM and IgG. It has relative specifity and shows cross-reaction with other basic proteins. The cytotoxic antibody was found in only 8% of healthy persons. Patients with multiple sclerosis were positive in 87% of the cases and in acute cases in 94%. In other neurological diseases cytotoxic antibody was present in 64%. The occurrence of cytotoxic antibody to myelin protein is not specific for a particular neurological disorder, especially not for multiple sclerosis. Cytotoxic antibodies arise as a secondary phenomenon, they are not the cause of the disease involved. They appear to be suitable, however, to determine, in association with cellular immunological reactions against myelin which may be regarded as the "primary" immunological processes, the demyelination process in the multiple sclerosis focus.
