Enhanced inflammation and suppressed adaptive immunity in COVID-19 with prolonged RNA shedding
Little is known regarding why a subset of COVID-19 patients exhibited prolonged positivity of SARS-CoV-2 infection. Here, we found that patients with long viral RNA course (LC) exhibited prolonged high-level IgG antibodies and higher regulatory T (Treg ...

Ebola virus VP30 and nucleoprotein interactions modulate viral RNA synthesis [PDF]
Ebola virus (EBOV) is an enveloped negative-sense RNA virus that causes sporadic outbreaks with high case fatality rates. Ebola viral protein 30 (eVP30) plays a critical role in EBOV transcription initiation at the nucleoprotein (eNP) gene, with ...

RNA Interference for Viral Infections [PDF]
The treatment of viral infections has relied on pre-emptive vaccination or use of a limited range of anti-viral drugs. However, the majority of viruses have no available drugs and treatment is merely supportive. RNA interference (RNAi) offers the ability to directly and rapidly treat virus infections via the targeting of viral genes.

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

A novel mechanism underlying the innate immune response induction upon viral-dependent replication of host cell mRNA: A mistake of +sRNA viruses' replicases [PDF]
Viruses are lifeless particles designed for setting virus-host interactome assuring a new generation of virions for dissemination. This interactome generates a pressure on host organisms evolving mechanisms to neutralize viral infection, which places the

The DEAD-box RNA helicase DDX6 is required for efficient encapsidation of a retroviral genome.
Viruses have to encapsidate their own genomes during the assembly process. For most RNA viruses, there are sequences within the viral RNA and virion proteins needed for high efficiency of genome encapsidation.

Reovirus Nonstructural Protein σNS Recruits Viral RNA to Replication Organelles
The function of the mammalian orthoreovirus (reovirus) σNS nonstructural protein is enigmatic. σNS is an RNA-binding protein that forms oligomers and enhances the stability of bound RNAs, but the mechanisms by which it contributes to reovirus replication

Is HIV-1 RNA dimerization a prerequisite for packaging? Yes, no, probably? [PDF]
During virus assembly, all retroviruses specifically encapsidate two copies of full-length viral genomic RNA in the form of a non-covalently linked RNA dimer.

يلعب إسكات الجينات (إسكات الحمض النووي الريبي) دورًا أساسيًا في الدفاع المضاد للفيروسات في النباتات والفطريات واللافقاريات. تقوم الفيروسات بتشفير البروتينات التي تمنع إسكات الجينات لمواجهة دفاع المضيف. تم تحديد المثبطات الفيروسية لإسكات الحمض النووي الريبي (RSVs) من جميع الفيروسات النباتية تقريبًا التي تولد وبعض فيروسات الحشرات والثدييات. كشفت الدراسات

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
