The interferon (IFN)-inducing capacity of different isolates of vesicular stomatitis virus (VSV) of the Indiana (IN) and New Jersey (NJ) serotypes were measured to assess the extent of variability of this phenotype. Over 200 preparations of wild-type field isolates, laboratory strains, and plaque-derived subpopulations were examined. Marked heterogeneity was found in the ability of these viruse...

The reovirus fusion-associated small transmembrane (FAST) proteins are the smallest known viral fusogens (∼100-150 amino acids) and efficiently induce cell-cell fusion and syncytium formation in multiple cell types. Syncytium formation enhances cell-cell virus transmission and may also induce immunogenic cell death, a form of apoptosis that stimulates immune recognition of tumor cells. These pr...

Vesicular stomatitis virus (VSV) has been shown previously to be capable of undergoing rapid mutational change during sequential experimental infections in various tissue culture cell systems (J. Holland, K. Spindler, F. Horodyski, E. Grabau, S. Nichol, and S. Vandepol, Science 215:1577-1585, 1982). The present study was undertaken to determine the degree of genetic diversity and evolution of t...

Prostaglandins of the A series were found to strongly suppress the replication of vesicular stomatitis virus (VSV) in mouse L fibroblasts. The highest non-toxic dose of PGA1, 4 micrograms/ml, decreased VSV production by 93.6%. At this dose, PGA1 did not alter DNA, RNA or protein synthesis in uninfected L cells for periods up to 24 h, whereas it further suppressed protein synthesis and slightly ...

UNLABELLED Codon pair bias (CPB), which has been observed in all organisms, is a neglected genomic phenomenon that affects gene expression. CPB results from synonymous codons that are paired more or less frequently in ORFeomes regardless of codon bias. The effect of an individual codon pair change is usually small, but when it is amplified by large-scale genome recoding, strikingly altered biol...

Ross River virus (RRV) and Semliki Forest virus (SFV) are two alphaviruses that have a high degree of amino acid homology, as well as a very broad host range. We show here that envelope glycoproteins derived from both viruses can pseudotype human immunodeficiency virus type 1 (HIV-1)-derived lentivirus vectors. Both RRV and SFV glycoproteins considerably expand the host range of the lentivirus ...

Gene transduction and expression efficiencies among several type cell lines were compared by using vesicular stomatitis virus-glycoprotein (VSV-G) pseudotyped human immunodeficiency virus type-1 (HIV-1) based lentivirus vector. Large discrepancies of the efficiencies were shown among them. B lymphocytes showed high susceptibility of the gene transduction and expression, while other cell lines m...

Prostaglandin A (PGA) exhibits antiviral activity against RNA and DNA viruses. The effect of PGA1 on vesicular stomatitis virus (VSV) was investigated. When VSV-infected L-1210 cells were kept in the presence of PGA1 the amount of all five viral proteins and their respective mRNAs was dose-dependently decreased. To determine whether the effect was on viral transcription or translation, the temp...

Multiple myeloma is a radiosensitive malignancy that is currently incurable. Here, we generated a novel recombinant vesicular stomatitis virus [VSV( 51)-NIS] that has a deletion of methionine 51 in the matrix protein and expresses the human sodium iodide symporter (NIS) gene. VSV( 51)-NIS showed specific oncolytic activity against myeloma cell lines and primary myeloma cells and was able to rep...

To analyze the antiviral protective capacities of CD4(+) T helper (Th) cell subsets, we used transgenic T cells expressing an I-A(b)-restricted T cell receptor specific for an epitope of vesicular stomatitis virus glycoprotein (VSV-G). After polarization into Th1 or Th2 effectors and adoptive transfer into T cell-deficient recipients, protective capacities were assessed after infection with dif...
