Cell Walls and the Convergent Evolution of the Viral Envelope.
Why some viruses are enveloped while others lack an outer lipid bilayer is a major question in viral evolution but one that has received relatively little attention. The viral envelope serves several functions, including protecting the RNA or DNA molecule(s), evading recognition by the immune system, and facilitating virus entry. Despite these commonalities, viral envelopes come in a wide varie...
متن کاملInfluence of viral envelope on Newcastle disease virus infection.
The adsorption characteristics of Newcastle disease virus (NDV) propagated in chicken cells (NDV-C) and in human cells (NDV-H) were examined. Adsorption experiments performed at different temperatures indicated that virus propagated in a particular cell infected that cell type more readily than did virus propagated in a different host. For example, NDV-C was more efficient in initiating infecti...
متن کاملThe Simian virus 40 late viral protein VP4 disrupts the nuclear envelope for viral release.
Simian virus 40 (SV40) appears to initiate cell lysis by expressing the late viral protein VP4 at the end of infection to aid in virus dissemination. To investigate the contribution of VP4 to cell lysis, VP4 was expressed in mammalian cells where it was predominantly observed along the nuclear periphery. The integrity of the nuclear envelope was compromised in these cells, resulting in the misl...
متن کاملFormation of influenza virus particles lacking hemagglutinin on the viral envelope.
We investigated the intracellular block in the transport of hemagglutinin (HA) and the role of HA in virus particle formation by using temperature-sensitive (ts) mutants (ts134 and ts61S) of influenza virus A/WSN/33. We found that at the nonpermissive temperature (39.5 degrees C), the exit of ts HA from the rough endoplasmic reticulum to the Golgi complex was blocked and that no additional bloc...
متن کاملBorna disease virus requires cholesterol in both cellular membrane and viral envelope for efficient cell entry.
Borna disease virus (BDV), the prototypic member of the family Bornaviridae within the order Mononegavirales, provides an important model for the investigation of viral persistence within the central nervous system (CNS) and of associated brain disorders. BDV is highly neurotropic and enters its target cell via receptor-mediated endocytosis, a process mediated by the virus surface glycoprotein ...
