Effect of Measles Virus Antibodies on a Measles SSPE Virus Persistently Infected C6 Rat Glioma Cell Line

Non-Measles Hemadsorption in a Cell Line Persistently Infected with Measles Virus (BGM/MV)

Adsorption of Rhesus monkey erythrocytes to the plasma membranes of measles virusinfected cells is frequently carried out to detect the presence of plasma membrane-associated measles virus hemagglutinin. The hemagglutinin is a viral genome-coded structural glycoprotein of the measles virion that is associated with the plasma membrane of the host cell during measles virus replication. BGM/MV,ano...

Growth of measles virus in cultures of rat glioma cells.

The interaction of measles virus with RG-6 cells derived from rat glioma was investigated. When a culture of RG-6 cells was infected with measles virus, the synthesis of viral antigens was detected in very few cells, at most 5%. The apparent resistance to measles virus infection was also repeatedly found in all of the subclonal cells derived form RG-6 cells. Although all of the virus-synthesizi...

Complementation analysis of measles virus mutants isolated from persistently infected lymphoblastoid cell lines.

Human lymphoblastoid cell lines persistently infected with measles virus release a heterogeneous population of virions. At least 80% of the infectious particles were temperature sensitive for plaque formation at 39 degrees C. Plaque-purified temperature-sensitive mutants from four persistently infected human lymphoblastoid cell lines were shown to be heterogeneous with respect to efficiency of ...

Reversal of the measles virus-mediated increase of phosphorylating activity in persistently infected mouse neuroblastoma cells by anti-measles virus antibodies.

To investigate the effect of persistent measles virus infection on signal transduction in cells of neuronal origin, the mouse neuroblastoma cell line NS20Y/MS, which is persistently infected with measles virus, was used. The results demonstrate an approximate 50% increase in total phosphorylation and a similar increase in protein kinase C (PKC) activity. Western blot analysis with anti-total PK...
