An unusual intranuclear structure (? viral nucleocapsid) in the brain in subacute sclerosing panencephalitis.

Enrichment of measles virus-like RNA in the nucleocapsid fraction isolated from subacute sclerosing panencephalitis brains.

A procedure has been developed which facilitates the detection of measles virus RNA sequences in human brains. The procedure involves isolating subviral components (nucleocapsids) from brain tissues prior to RNA purification, followed by hybridization of these RNAs to cDNA synthesized from measles virus 50 S RNA template. Using these techniques we were able to obtain an RNA fraction which was m...

Subacute sclerosing panencephalitis--the continuing threat.

Clinical, epidemiological and laboratory findings of four patients with subacute sclerosing panencephalitis (SSPE), diagnosed in Croatia in 2002, were examined. Patient age at disease onset ranged from 5-11 years. All patients were vaccinated regularly with MMR-vaccine. Two patients had a history of measles infection at the age of six and seven months, respectively. In the other two patients, t...

Subacute sclerosing panencephalitis: detection of measles virus RNA in appendix lymphoid tissue before clinical signs.

An appendix removed 15 days before onset of symptoms of subacute sclerosing panencephalitis was examined retrospectively for measles virus ribonucleic acid (RNA). Tissue sections hybridised in situ to a cloned measles virus probe of deoxyribonucleic acid specific for nucleocapsid protein showed that many cells of the lymphoid tissue contained measles virus RNA. In contrast, only a few infected ...
