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 ...

Human and murine IFIT1 proteins do not restrict infection of negative-sense RNA viruses of the Orthomyxoviridae, Bunyaviridae, and Filoviridae families [PDF]

open access: yes, 2015
UNLABELLED: Interferon-induced protein with tetratricopeptide repeats 1 (IFIT1) is a host protein with reported cell-intrinsic antiviral activity against several RNA viruses.

Immune responses to RNA virus infections of the CNS [PDF]

open access: yesBMC Proceedings, 2003
A successful outcome for the host of virus infection of the central nervous system (CNS) requires the elimination of the virus without damage to essential non-renewable cells, such as neurons. As a result, inflammatory responses must be tightly controlled, and many unique mechanisms seem to contribute to this control.

Viral suppressors from members of the family Closteroviridae combating antiviral RNA silencing: a tale of a sophisticated arms race in host-pathogen interactions

open access: yesPhytopathology Research, 2021
RNA silencing is an evolutionarily homology-based gene inactivation mechanism and plays critical roles in plant immune responses to acute or chronic virus infections, which often pose serious threats to agricultural productions.

Discovery and Community Dynamics of Novel ssRNA Mycoviruses in the Conifer Pathogen Heterobasidion parviporum

open access: yesFrontiers in Microbiology, 2021
Heterobasidion species are highly destructive basidiomycetous conifer pathogens of the Boreal forest region. Earlier studies have revealed dsRNA virus infections of families Curvulaviridae and Partitiviridae in Heterobasidion strains, and small RNA deep ...

Arboviruses and the challenge to establish systemic and persistent infections in competent mosquito vectors : the interaction with the RNAi mechanism [PDF]

open access: yes, 2019
Arboviruses are capable to establish long-term persistent infections in mosquitoes that do not affect significantly the physiology of the insect vectors. Arbovirus infections are controlled by the RNAi machinery via the production of viral siRNAs and the

An RNA virus can adapt to the multiplicity of infection.

open access: yesJournal of General Virology, 1998
RNA viruses evolve as complex distributions of mutants termed viral quasispecies. For this reason it is relevant to explore those environmental parameters that favour the selective advantage of some viral subpopulations over others. In the present study we provide direct evidence that the relative fitness of two competing viral subpopulations may ...

Infection initiated by the RNA pregenome of a DNA virus [PDF]

open access: yesJournal of Virology, 1991
We describe experiments demonstrating that after transfection into permissive cells, the RNA pregenome of an avian hepadnavirus, the duck hepatitis B virus, is infectious. Using a Sindbis virus expression vector, we showed that cytoplasmic synthesis of the pregenome resulted in hepadnaviral DNA synthesis.

Genetic characterization of Pepino mosaic virus isolates from Belgian greenhouse tomatoes reveals genetic recombination [PDF]

open access: yes, 2008
Over a period of a few years, Pepino mosaic virus (PepMV) has become one of the most important viral diseases in tomato production worldwide. Infection by PepMV can cause a broad range of symptoms on tomato plants, often leading to significant financial ...

Dual Effect of Organogermanium Compound THGP on RIG-I-Mediated Viral Sensing and Viral Replication during Influenza a Virus Infection

open access: yesViruses, 2021
The interaction of viral nucleic acid with protein factors is a crucial process for initiating viral polymerase-mediated viral genome replication while activating pattern recognition receptor (PRR)-mediated innate immune responses. It has previously been
