Morbillivirus downregulation of CD46.
There is evidence that CD46 (membrane cofactor protein) is a cellular receptor for vaccine and laboratory-passaged strains of measles virus (MV). Following infection with these MV strains, CD46 is downregulated from the cell surface, and consequent complement-mediated lysis has been shown to occur upon infection of a human monocytic cell line. The MV hemagglutinin (H) protein alone is capable o...
متن کاملCell-to-cell contact via measles virus haemagglutinin-CD46 interaction triggers CD46 downregulation.
CD46 downregulation by measles virus (MV) occurs after expression of virus haemagglutinin (H) protein on the surface of the infected cell and is a consequence of CD46-H interaction on the cell membrane. To assess whether CD46 downregulation also occurs after CD46-H interaction when these two molecules are expressed on distinct cells, we used human T cell line Jurkat (expressing CD46) and transf...
متن کاملDifferential downregulation of CD46 by measles virus strains.
Recently, we found that several lymphotropic wild-type isolates of measles virus (MV) did not lead to the downregulation of CD46 following infection. We hypothesized that either the site of virus isolation, e.g., throat swab versus peripheral blood mononuclear cells, or the cell type used for the isolation may exert selective pressure on a mixed population of viruses, resulting in isolates with...
متن کاملMorbillivirus Infections: An Introduction
Research on morbillivirus infections has led to exciting developments in recent years. Global measles vaccination coverage has increased, resulting in a significant reduction in measles mortality. In 2011 rinderpest virus was declared globally eradicated - only the second virus to be eradicated by targeted vaccination. Identification of new cellular receptors and implementation of recombinant v...
متن کامل[Entry mechanism of morbillivirus family].
The genus Morbillivirus includes measles virus, canine distemper virus and rinderpest virus. These are highly contagious and exhibit high mortality. These viruses have the attachment glycoprotein, hemagglutinin (H), at the virus surface, which bind to signaling lymphocyte activation molecule (SLAM) and Nectin 4 as receptors for the entry. However, the molecular mechanism for this entry has been...
