However, prospective studies relating results of lymphoblastic transformation to the clinical course of multiple sclerosis have not been reported. In the present study, both lymphoblastic transformation and migration inhibitory factor assays were used, and results related to the temporal course of multiple sclerosis. Results of the present investigation show that cell-mediated hypersensitivity to myelin basic A1 protein is most significant during exacerbations of multiple sclerosis. Responses obtained employing either the lymphoblastic transformation or migration inhibitory factor assay were equally significant. The results support the hypothesis that a factor suppressing deoxyribonucleic acid synthesis is present in multiple sclerosis and is inhibited by the use of steroids.
