Scanning electron microscopic studies of virus-infected cells. I. Cytopathic effects and maturation of vesicular stomatitis virus in L2 cells.
L2 cells infected with vesicular stomatitis virus under single-cycle conditions have been studied by scanning electron microscopy after preparation by the critical point drying technique. Three dimensional images of intact cells show bullet-shaped vesicular stomatitis virus virions budding singly and in radiating clusters both from the plasma membrane between cellular microvilli and from the si...
متن کاملN-Myc expression enhances the oncolytic effects of vesicular stomatitis virus in human neuroblastoma cells
N-myc oncogene amplification is associated but not present in all cases of high-risk neuroblastoma (NB). Since oncogene expression could often modulate sensitivity to oncolytic viruses, we wanted to examine if N-myc expression status would determine virotherapy efficacy to high-risk NB. We showed that induction of exogenous N-myc in a non-N-myc-amplified cell line background (TET-21N) increased...
متن کاملInhibition of a vesicular stomatitis virus mutant by rifampin.
Rifampin reversibly inhibits the intracellular replication of a VSV mutant, whereas a revertant variant selected from this viral population, as well as the wild strain, are not affected by this drug. Rifampin inhibits transcriptase activity of the sensitive mutant only and, consequently, total viral RNA synthesis decreases significantly in the cells.
متن کاملA fusion-defective mutant of the vesicular stomatitis virus glycoprotein.
We have recently described an assay in which a temperature-sensitive mutant of vesicular stomatitis virus (VSV; mutant tsO45), encoding a glycoprotein that is not transported to the cell surface, can be rescued by expression of wild-type VSV glycoproteins from cDNA (M. Whitt, L. Chong, and J. Rose, J. Virol. 63:3569-3578, 1989). Here we examined the ability of mutant G proteins to rescue tsO45....
متن کاملhsp70-dependent antiviral immunity against cytopathic neuronal infection by vesicular stomatitis virus.
The major inducible 70-kDa heat shock protein (hsp70) protects against measles virus (MeV) neurovirulence in the mouse that is caused by a cell-associated noncytolytic neuronal infection. Protection is type I interferon (IFN) dependent, and we have established a novel axis of antiviral immunity in which hsp70 is released from virus-infected neurons to induce IFN-β in macrophages. The present wo...
