Viral RNA load in plasma is associated with critical illness and a dysregulated host response in COVID-19

open access: yesCritical Care, 2020
Background COVID-19 can course with respiratory and extrapulmonary disease. SARS-CoV-2 RNA is detected in respiratory samples but also in blood, stool and urine. Severe COVID-19 is characterized by a dysregulated host response to this virus.

Protein expression redirects vesicular stomatitis virus RNA synthesis to cytoplasmic inclusions. [PDF]

open access: yesPLoS Pathogens, 2010
Positive-strand and double-strand RNA viruses typically compartmentalize their replication machinery in infected cells. This is thought to shield viral RNA from detection by innate immune sensors and favor RNA synthesis. The picture for the non-segmented

Ribose 2′-O-methylation provides a molecular signature for the distinction of self and non-self mRNA dependent on the RNA sensor Mda5 [PDF]

open access: yes, 2011
The 5'-cap-structures of higher eukaryote mRNAs are ribose 2'-O-methylated. Likewise, a number of viruses replicating in the cytoplasm of eukayotes have evolved 2'-O-methyltransferases to modify autonomously their mRNAs.

Host and viral RNA-binding proteins involved in membrane targeting, replication and intercellular movement of plant RNA virus genomes

open access: yesFrontiers in Plant Science, 2014
Many plant viruses have positive-strand RNA [(+)RNA] as their genome. Therefore, it is not surprising that RNA-binding proteins (RBPs) play important roles during (+)RNA virus infection in host plants.

Oyster RNA-seq data support the development of Malacoherpesviridae genomics [PDF]

open access: yes, 2017
The family of double-stranded DNA (dsDNA) Malacoherpesviridae includes viruses able to infect marine mollusks and detrimental for worldwide aquaculture production. Due to fast-occurring mortality and a lack of permissive cell lines, the available data on

Initiation of viral RNA-dependent RNA polymerization

open access: yesJournal of General Virology, 2004
This review summarizes the combined insights from recent structural and functional studies of viral RNA-dependent RNA polymerases (RdRPs) with the primary focus on the mechanisms of initiation of RNA synthesis. Replication of RNA viruses has traditionally been approached using a combination of biochemical and genetic methods.

Radial distribution of RNA genome packaged inside spherical viruses

open access: yes, 2008
The problem of RNA genomes packaged inside spherical viruses is studied. The viral capsid is modeled as a hollowed sphere. The attraction between RNA molecules and the inner viral capsid is assumed to be non-specific and occurs at the inner capsid ...

Viruses and the cellular RNA decay machinery. [PDF]

open access: yes, 2010
The ability to control cellular and viral gene expression, either globally or selectively, is central to a successful viral infection, and it is also crucial for the host to respond and eradicate pathogens.

Polygenic viral factors enable efficient mosquito-borne transmission of African Zika virus

open access: yesNature Communications
Zika virus (ZIKV) is a mosquito-borne orthoflavivirus primarily transmitted among humans by Aedes aegypti. Over the past two decades, it has caused significant outbreaks associated with birth defects and neurological disorders.

Novel ATP-independent RNA annealing activity of the dengue virus NS3 helicase.

open access: yesPLoS ONE, 2012
The flavivirus nonstructural protein 3 (NS3) bears multiple enzymatic activities and represents an attractive target for antiviral intervention. NS3 contains the viral serine protease at the N-terminus and ATPase, RTPase, and helicase activities at the C-
