Western blot analyses of measles virus antibody in normal persons and in patients with multiple sclerosis, subacute sclerosing panencephalitis, or atypical measles.

ABSTRACT

A version of the Western blot was developed to detect serum antibodies against measles virus polypeptides. With this technique, a seroepidemiological survey of antibodies to the several measles virus proteins in diverse measles-related conditions was conducted. The sera were obtained from individuals with a recent or long-past history of natural measles, from persons with a history of immunization with live attenuated measles vaccine, and from patients with multiple sclerosis, subacute sclerosing panencephalitis, or atypical measles. The findings indicated that live attenuated measles vaccine elicits an antibody response qualitatively resembling that of a natural infection. In addition, multiple sclerosis patients made less antibody to the measles virus M protein than did individuals with a long-past history of natural measles. Thus, the immunological reaction of multiple sclerosis patients to measles virus is qualitatively, as well as quantitatively, different from that of normal persons. Finally, persons with subacute sclerosing panencephalitis and atypical measles mounted abnormally high antibody responses to measles virus polypeptides, in particular the P protein.
