Rotavirus Replication Requires a Functional Proteasome for Effective Assembly of Viroplasms [PDF]
ABSTRACTThe ubiquitin-proteasome system has been shown to play an important role in the replication cycle of different viruses. In this study, we describe a strong impairment of rotavirus replication upon inhibition of proteasomal activity. The effect was evidenced at the level of accumulation of viral proteins, viral RNA, and yield of infective ...

Abstract To study viral infection, the direct structural visualization of the viral life cycle consisting of virus attachment, entry, replication, assembly and transport is essential. Although conventional electron microscopy (EM) has been extremely helpful in the investigation of virus–host cell interactions, three‐dimensional (3D) EM not only ...

Characterization of viroplasm-like structures by co-expression of NSP5 and NSP2 across rotavirus species A to J. [PDF]
Rotaviruses (RVs) are classified into nine species, A–D and F–J, with species A being the most studied. In rotavirus of species A (RVA), replication occurs in viroplasms, which are cytosolic globular inclusions composed of main building block proteins ...

Lipid Droplets in Virus Replication. [PDF]
Intracellular pathogens rely on host metabolic networks for multiplication. Enveloped viruses need lipids for formation of the viral envelope and positive sense RNA viruses that replicate in membranous inclusions require lipids for formation of the replication compartments.

Monitoring SARS-CoV-2 Dissemination in Wastewater and Virus Isolation in Cell Cultures: An Integrated Approach for Pathogen Detection and Surveillance. [PDF]
ABSTRACT Our study presents wastewater (WW) monitoring data, focusing on determining the infectivity of SARS‐CoV‐2 in the collected samples. Additionally, a panel of different viruses has been tested in the WW samples. The untreated WW monitoring campaign took place over 1 year in Bucharest, with approximately 300 samples being collected twice a week ...

A little less aggregation a little more replication: Viral manipulation of stress granules
Viruses depend entirely on host machinery and therefore aim to conquer the host and defeat its defenses to co‐opt its resources for its own replication. Improved understanding of how viruses counteract host immune responses such as stress granule assembly, detailed here, will inform future antiviral therapeutic strategies.

Sonchus Yellow Net Rhabdovirus Nuclear Viroplasms Contain Polymerase-Associated Proteins [PDF]
ABSTRACTWe have initiated a study of the cytopathology of nucleorhabdoviruses by analyzing the subcellular localization of sonchus yellow net virus (SYNV) genomic and antigenomic RNAs and the encoded polymerase proteins. In situ hybridizations demonstrated that the minus-strand genomic RNA sequences are restricted to the nuclei of infected cells, while

Rotavirus infects human biliary epithelial cells and stimulates secretion of cytokines IL-6 and IL-8 via MAPK pathway [PDF]
Biliary atresia (BA) is an infantile inflammatory cholangiopathy of unknown etiology although epidemiologic studies and animal models utilizing rotavirus (RV) have suggested a role for viral infection.

Evidence that avian reovirus σNS is an RNA chaperone: implications for genome segment assortment. [PDF]
Reoviruses are important human, animal and plant pathogens having 10-12 segments of double-stranded genomic RNA. The mechanisms controlling the assortment and packaging of genomic segments in these viruses, remain poorly understood.
