African swine fever virus (ASFV) infection causes endosomal reorganization. Here, we show that the virus causes endosomal congregation close to the nucleus as the infection progresses, which is necessary to build a compact viral replication organelle. ASFV enters the cell by the endosomal pathway and reaches multivesicular late endosomes. Upon uncoating and fusion, the virus should exit to the ...
After DNA viruses enter the nucleus, they initiate a transcriptional cascade which is followed by replication. We investigated whether these processes take place at specific nuclear sites or, as suggested by the mode of entry, randomly throughout the nucleus. Three distinct nuclear domains, nuclear factor-1 sites, coiled bodies, and nuclear domain 10 (ND10), were used as markers to investigate ...
The occurrence of homologous interference in the replication of infectious pancreatic necrosis virus was demonstrated after successive passages of partially purified virus at high input multiplicities in trout and Atlantic salmon cell cultures. Pretreatment of cell cultures with interfering virus inhibited the replication of homologous standard infectious virus but not unrelated viruses. The ab...
BACKGROUND Silver nanoparticles possess many unique properties that make them attractive for use in biological applications. Recently they received attention when it was shown that 10 nm silver nanoparticles were bactericidal, which is promising in light of the growing number of antibiotic resistant bacteria. An area that has been largely unexplored is the interaction of nanomaterials with viru...
Varicella-zoster virus (VZV) establishes a lifelong latent infection in the dorsal root ganglia of the host. During latency, a subset of virus-encoded regulatory proteins is detected; however, they are excluded from the nucleus. ORF29p, a single-stranded DNA binding protein, is one of these latency-associated proteins. We searched for cell proteins that interact with ORF29p and identified BAG3....
To determine the relationship between influenza A virus replication and innate antiviral immune responses, rhesus monkeys were given oseltamivir before influenza A/Memphis/7/01 (H1N1) challenge. We found that oseltamivir treatment significantly reduced viral replication in the trachea (p < 0.029). Further, in the trachea of both treated and untreated monkeys the mRNA levels of most innate antiv...
We developed a system for complete replication of encephalomyocarditis virus (EMCV) in a test tube by using an in vitro translation extract from Krebs-2 cells. Efficient virus synthesis occurred in a narrow range of Mg(2+) and EMCV RNA concentrations. Excess input RNA impaired RNA replication and virus production but not translation. This suggests the existence of a negative-feedback mechanism ...
The replication of mumps virus was studied in human continuous lymphoblastoid cell lines (LCLs) with T or B characteristics and in lymphocyte subpopulations derived from peripheral blood. T-LCLs supported effective virus replication as shown by high titers of free and cell-associated virus over 1 to 4 days after infection. By immunofluorescence analysis, the majority of cells were positive for ...
context viral hepatitis and the consumption of alcohol are recognized as important reasons for the development of liver disease throughout the world. it would also seem that chronic alcoholism causes more severe and rapid progression of liver disease in patients with chronic hepatitis c, leading to more frequent liver cirrhosis and hepatocellular carcinoma. evidence acquisition the data for thi...
Influenza A virus RNA replication requires an intricate regulatory network involving viral and cellular proteins. In this study, we examined the roles of cellular ubiquitinating/deubiquitinating enzymes (DUBs). We observed that downregulation of a cellular deubiquitinating enzyme USP11 resulted in enhanced virus production, suggesting that USP11 could inhibit influenza virus replication. Conver...
