A 212-nt long RNA structure in the Tobacco necrosis virus-D RNA genome is resistant to Xrn degradation [PDF]

open access: yes, 2019
Plus-strand RNA viruses can accumulate viral RNA degradation products during infections. Some of these decay intermediates are generated by the cytosolic 5′-to-3′ exoribonuclease Xrn1 (mammals and yeast) or Xrn4 (plants) and are formed when the enzyme ...

The Lassa Virus Stable Signal Peptide Undergoes a Conformational Change to Aid Viral Fusion

open access: yesChemistry – A European Journal, Volume 31, Issue 18, March 25, 2025.
The unique stable signal peptide (SSP) of the Lassa virus glycoprotein complex undergoes a conformational change during pH‐dependent viral fusion. This revels a potential mechanism by which the enigmatic SSP influences the fusion process through interactions it makes with the fusion protein, glycoprotein 2 (GP2).

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.

Two Birds With One Stone: RNA Virus Strategies to Manipulate G3BP1 and Other Stress Granule Components

open access: yesWIREs RNA, Volume 16, Issue 2, March/April 2025.
Stress granules emerging during viral infection can play both pro‐ and antiviral roles. RNA viruses use various strategies to antagonize their formation, including the degradation, inhibition, or sequestration of G3BP1, a key stress granule protein. However, biochemical and structural insights into these mechanisms have been reported for only a handful

Production of CXC and CC chemokines by human antigen-presenting cells in response to Lassa virus or closely related immunogenic viruses, and in cynomolgus monkeys with lassa fever. [PDF]

open access: yes, 2014
International audienceThe pathogenesis of Lassa fever (LF), a hemorrhagic fever endemic to West Africa, remains unclear. We previously compared Lassa virus (LASV) with its genetically close, but nonpathogenic homolog Mopeia virus (MOPV) and demonstrated ...

Viral Live‐Attenuated Vaccines (LAVs): Past and Future Directions

open access: yesAdvanced Science, Volume 12, Issue 3, January 20, 2025.
Live attenuated vaccines represent a delicate equilibrium between virulence and immunogenicity during adaptation. The process of animal adaptation involves artificial selection; therefore, adapted viruses exhibit decreased pathogenicity to their original hosts and increased pathogenicity to their adapted hosts.

Future Developments and Applications of the Vaccines against Dangerous Viral Infections, RNA-Replicon-Based, Obtained from the Venezuelan Equine Encephalomyelitis Virus

open access: yesПроблемы особо опасных инфекций, 2014
The members of the Filoviridae (Marburg and Ebola viruses) and Arenaviridae (Lassa, Lujo, Machupo, Junin, Guanarito, Sabia viruses) families are the etiological agents of particularly dangerous viral hemorrhagic fevers.

Filovirus receptor NPC1 contributes to species-specific patterns of ebolavirus susceptibility in bats [PDF]

open access: yes, 2015
Biological factors that influence the host range and spillover of Ebola virus (EBOV) and other filoviruses remain enigmatic. While filoviruses infect diverse mammalian cell lines, we report that cells from African straw-colored fruit bats (Eidolon helvum)

The vaccines based on the replicon of the venezuelan equine encephalomyelitis virus against viral hemorrhagic fevers

open access: yesВопросы вирусологии, 2015
The status of the various recombinant DNA and RNA-derived candidate vaccines, as well as the Venezuelan equine encephalomyelitis virus (VEEV) replicon vaccine system against extremely hazardous viral hemorrhagic fevers, were reviewed.
