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

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]
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
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.

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]
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)
