title: Serum-mediated oligodendrocyte cytotoxicity in multiple sclerosis patients and controls.
abstract: We examined serum-mediated cytotoxicity on cultured rat oligodendrocytes, using serum from patients with acute or chronic progressive multiple sclerosis and normal controls. We found heat-labile serum factors in serum from MS and also in controls. The cytotoxic effects of MS and normal sera were not restored by adding a source of complement. Despite apparent lack of disease specificity, such factors might damage oligodendrocytes if they gained access to these cells through a damaged blood-brain barrier in MS or other disorders.
