The brain has a tightly regulated environment that protects neurons and limits inflammation, designated "immune privilege." However, there is not an absolute lack of an immune response. We tested the ability of the brain to initiate an innate immune response to a virus, which was directly injected into the brain parenchyma, and to determine whether this response could limit viral spread. We inj...

The production of infectious vesicular stomatitis (VSV) and Newcastle disease virus can be completely inhibited by 2-deoxy-d-glucose in pyruvate-containing medium, if virus either grown in pyruvate-containing medium or dialyzed against phosphate-buffered saline is used for infection. Under these conditions, the synthesis of all VSV proteins is reduced. VSV RNA, which is synthesized at reduced r...

Abbreviations used: HIV, human immunodeficiency virus ; SIV, simian immunodeficiency virus; Env, envelope glycoprotein, VSV-G, vesicular stomatitis virus glycoprotein; GPCR, G-protein coupled receptor; CKR, chemokine receptor, PTX, Bordetella pertussis toxin; SH3, src homology-3; PACS-1, phosphofurin acidic cluster sorting protein-1; MHC, major histocompatibility class; GFP, green fluorescent p...

Naïve CD4(4) T cells are resistant to both HIV R5 env and vesicular stomatitis virus G protein (VSV-G)-mediated fusion. However, viral particles carrying both HIV R5 env and VSV-G infect naïve cells by an unexplained mechanism. We show that VSV-G-pseudotyped virus cannot fuse to unstimulated cells because the viral particles cannot be endocytosed. However, virions carrying both HIV R5 env and V...

In the previous papers of this series (1, 2), it was shown that the antigen-reactive T cells capable of replicating vesicular stomatitis virus (VSV) ] developed in the spleen of mice after the immunization with sheep erythrocytes (SRBC). The time-course of the development of VSV-replicating T cells did not correlate with that of delayed-type hypersensitivity (DTH), helper T cells, or suppressor...

Tubulin acts as a positive transcription factor for in vitro RNA synthesis by two different negative-strand viruses: Sendai virus, a paramyxovirus; vesicular stomatitis virus (VSV), a rhabdovirus. A monoclonal antibody directed against beta-tubulin completely inhibited not only mRNA synthesis and RNA replication catalyzed in vitro by extracts of cells infected with either virus but also mRNA sy...

To determine whether vesicular stomatitis virus (VSV) infection of Culicoides sonorensis Wirth & Jones (Diptera: Ceratopogonidae) affects subsequent blood-feeding behavior, midges injected with either virus-infected or virus-free cell lysates were allowed to blood feed for short (10-min) or long (60-min) periods on 2, 3, and 4 d postinoculation (DPI). Generalized linear mixed models were fit to...

Oncolytic viruses constitute a promising therapy against malignant gliomas (MGs). However, virus-induced type I IFN greatly limits its clinical application. The kinase mammalian target of rapamycin (mTOR) stimulates type I IFN production via phosphorylation of its effector proteins, 4E-BPs and S6Ks. Here we show that mouse embryonic fibroblasts and mice lacking S6K1 and S6K2 are more susceptibl...

Since the development of vaccinia virus as a vaccine vector in 1984, the utility of numerous viruses in vaccination strategies has been explored. In recent years, key improvements to existing vectors such as those based on adenovirus have led to significant improvements in immunogenicity and efficacy. Furthermore, exciting new vectors that exploit viruses such as cytomegalovirus (CMV) and vesic...

In this study, an enzyme-linked immunosorbent assay (ELISA) using glycoprotein and a monoclonal antibody (MAb) was developed for the detection of antibodies to vesicular stomatitis virus (VSV) serotype New Jersey (NJ). The glycoprotein to be used as a diagnostic antigen was extracted from partially purified VSV-NJ, and a neutralizing MAb specific to VSV-NJ was incorporated to compete with antib...
