Stimulation of human dendritic cells by wild-type and M protein mutant vesicular stomatitis viruses engineered to express bacterial flagellin.
Vesicular stomatitis viruses (VSVs) containing wild-type (wt) or mutant matrix (M) proteins are being developed as candidate vaccine vectors due to their ability to induce innate and adaptive immunity. Viruses with wt M protein, such as recombinant wild-type (rwt) virus, stimulate maturation of dendritic cells (DC) through Toll-like receptor 7 (TLR7) and its adaptor molecule MyD88. However, M p...
متن کاملRole of residues 121 to 124 of vesicular stomatitis virus matrix protein in virus assembly and virus-host interaction.
The recent solution of the crystal structure of a fragment of the vesicular stomatitis virus matrix (M) protein suggested that amino acids 121 to 124, located on a solvent-exposed loop of the protein, are important for M protein self-association and association with membranes. These residues were mutated from the hydrophobic AVLA sequence to the polar sequence DKQQ. Expression and purification ...
متن کاملRifampin-susceptible mutant of vesicular stomatitis virus: protein and RNA synthesis.
A rifampin-susceptible strain (VSV Rif+) was selected from the wild vesicular stomatitis virus (VSV) population unsusceptible to rifampin. The VSV Rif+ was blocked in its intracellular replication in the presence of rifampin. In cells, rifampin affected primarily VSV Rif+ transcription, but to a different extent than in a cell-free system. In addition, a decrease in the amount of VSV Rif+ prote...
متن کاملVesicular stomatitis viruses expressing wild-type or mutant M proteins activate apoptosis through distinct pathways.
Vesicular stomatitis virus (VSV) induces apoptosis by at least two mechanisms. The viral matrix (M) protein induces apoptosis via the mitochondrial pathway due to the inhibition of host gene expression. However, in some cell types, the inhibition of host gene expression by VSV expressing wild-type (wt) M protein delays VSV-induced apoptosis, indicating that another mechanism is involved. In sup...
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....
