Poliovirus Particles do not Form in Preinfected Cells with Reovirus
Background and Aims: Inhibition of viral growth in coinfected cells with two different viruses has been described. This phenomenon known as viral interference can occur in several virus host systems such as interference of enterovirus infection on poliovirus vaccine strains. In this study we superinfected reovirus infected HeLa cells with poliovirus to determine if poliovirus can replicate in s...
متن کاملNucleolin interacts with US11 protein of herpes simplex virus 1 and is involved in its trafficking.
Herpes simplex virus type 1 (HSV-1) infection induces profound nucleolar modifications at the functional and organizational levels, including nucleolar invasion by several viral proteins. One of these proteins is US11, which exhibits several different functions and displays both cytoplasmic localization and clear nucleolar localization very similar to that of the major multifunctional nucleolar...
متن کاملNucleolin interacts with influenza A nucleoprotein and contributes to viral ribonucleoprotein complexes nuclear trafficking and efficient influenza viral replication
Influenza viruses replicate their single-stranded RNA genomes in the nucleus of infected cells and these replicated genomes (vRNPs) are then exported from the nucleus to the cytoplasm and plasma membrane before budding. To achieve this export, influenza viruses hijack the host cell export machinery. However, the complete mechanisms underlying this hijacking remain not fully understood. We have ...
متن کاملViral proteinase requirements for the nucleocytoplasmic relocalization of cellular splicing factor SRp20 during picornavirus infections.
Infection of mammalian cells by picornaviruses results in the nucleocytoplasmic redistribution of certain host cell proteins. These viruses interfere with import-export pathways, allowing for the cytoplasmic accumulation of nuclear proteins that are then available to function in viral processes. We recently described the cytoplasmic relocalization of cellular splicing factor SRp20 during poliov...
متن کاملProcessing of a cellular polypeptide by 3CD proteinase is required for poliovirus ribonucleoprotein complex formation.
Poliovirus interactions with host cells were investigated by studying the formation of ribonucleoprotein complexes at the 3' end of poliovirus negative-strand RNA which are presumed to be involved in viral RNA synthesis. It was previously shown that two host cell proteins with molecular masses of 36 and 38 kDa bind to the 3' end of viral negative-strand RNA at approximately 3 to 4 h after infec...
