Measles virus (MV) hemagglutinin: evidence that attachment sites for MV receptors SLAM and CD46 overlap on the globular head.
Measles virus hemagglutinin (MVH) residues potentially responsible for attachment to the wild-type (wt) MV receptor SLAM (CD150) have been identified and localized on the MVH globular head by reference to a revised hypothetical structural model for MVH (www.pepscan.nl/downloads/measlesH.pdb). We show that the mutation of five charged MVH residues which are conserved among morbillivirus H protei...
متن کاملAntitumor Virotherapy by Attenuated Measles Virus (MV)
Antitumor virotherapy consists of the use of replication-competent viruses to infect and kill tumor cells preferentially, without damaging healthy cells. Vaccine-attenuated strains of measles virus (MV) are good candidates for this approach. Attenuated MV uses the CD46 molecule as a major entry receptor into cells. This molecule negatively regulates the complement system and is frequently overe...
متن کاملProductive measles virus brain infection and apoptosis in CD46 transgenic mice.
Measles virus (MV) infection causes acute childhood disease, associated in certain cases with infection of the central nervous system (CNS) and development of neurological disease. To develop a murine model of MV-induced pathology, we generated several lines of transgenic mice ubiquitously expressing as the MV receptor a human CD46 molecule with either a Cyt1 or Cyt2 cytoplasmic tail. All trans...
متن کاملEffect of measles virus (MV) on mitochondrial respiration.
BACKGROUND & OBJECTIVES Studies of interaction between viruses and mitochondria have shown that viruses can affect the mitochondria. Also linkage between human diseases and mitochondrial dysfunction has been revealed. We studied the effect of measles virus (MV) on cell respiration in MV infected Hela cells to see any possible changes in mitochondrial respiration. METHODS Total cell respiratio...
متن کاملDifferential permissivity to measles virus infection of human and CD46-transgenic murine lymphocytes.
Analysis of measles virus (MV) pathogenesis requires the development of an adequate small animal model of MV infection. In this study, permissivity to MV infection was compared in human and transgenic murine T lymphocytes, expressing different levels of the human MV receptor, CD46. Whereas MV binding and entry correlated with CD46 expression, higher levels of MV replication were always observed...
