Multiple sclerosis and measles: a study of cellular sensitization.

Lymphocyte sensitization to measles has been studied in comparable groups of multiple sclerosis, other neurologic disease and normal subjects. The macrophage electrophoretic mobility test has been used. No difference between the three groups has been found, though there is a small group of children with obscure neurological disease which might well be multiple sclerosis and which fails to mount an adequate response to measles. The role of measles (and other banal infections) in aetiopathogenesis of multiple sclerosis is briefly discussed.
