Expression of defective measles virus genes in brain tissues of patients with subacute sclerosing panencephalitis.

The persistence of measles virus in selected areas of the brains of four patients with subacute sclerosing panencephalitis (SSPE) was characterized by immunohistological and biochemical techniques. The five measles virus structural proteins were never simultaneously detectable in any of the brain sections. Nucleocapsid proteins and phosphoproteins were found in every diseased brain area, wherea...

Subacute Sclerosing Panencephalitis in Iran

Measles and subacute sclerosing panencephalitis virus proteins: lack of antibodies to the M protein in patients with subacute sclerosing panencephalitis.

Studies on the immunoprecipitation of the proteins of several different measles and subacute sclerosing panencephalitis (SSPE) virus strains from lysates of infected cells have revealed a relative lack of antibodies to the nonglycosylated viral membrane protein (M) in the sera of patients with SSPE, in contrast to a high level of antibodies to other viral proteins. No evidence was found for the...

Measles immunoglobulins in subacute sclerosing panencephalitis.

Normal responses of measles specific immunoglobulins M and G (IgM and IgG) were defined in 10 children with measles. Abnormal responses of measles IgM and IgG were found in both sera and cerebrospinal fluids from three cases of subacute sclerosing panencephalitis. In two patients the serum titres of measles IgM and IgG were abnormally high. The measles IgM was present during prolonged illnesses...

Subacute sclerosing panencephalitis measles virus: study of biological markers.

Comparative studies between two measles virus strains isolated from patients with subacute sclerosing panencephalitis (SSPE) and a prototype low tissue culture passage Edmonston measles virus are described. Differences were noted in several properties. The findings described in this report suggest that strains of measles virus associated with SSPE have different biological properties and appare...
