Identification of cellular proteins associated with human cytomegalovirus (HCMV) DNA replication suggests novel cellular and viral interactions.
Short and Sweet: Viral 5`-UTR as a Canonical and Non-Canonical Translation Initiation Switch
- BiologyJournal of cellular immunology
Cap-dependent and cap-independent translation initiation mechanisms are summarized and the unique ability of the BBV mRNA 5’-UTR to switch between these two modes of translation initiation in the context of the viral life cycle is elaborated.
Top Three Strategies of ss(+)RNA Plant Viruses: Great Opportunists and Ecosystem Tuners with a Small Genome
RNA viruses are increasingly treated not as micropathogens but as necessary regulators of ecosystem balance, and a fundamental understanding of this aspect of the role played by viruses in the ecosystem makes it possible to apply this knowledge to the creation of DNA insecticides.
Computational Prediction of Bacteriophage Host Ranges
Recently developed bioinformatic tools are reviewed that offer a promising and high-throughput alternative by computationally predicting the putative host ranges of bacteriophages, including those challenging to grow in laboratory environments.
The Impact of Epitranscriptomics on Antiviral Innate Immunity
At the virological level, epitranscriptomics can thus directly impact the viral life cycle itself, acting on viral or cellular proteins promoting replication, or impacting the innate antiviral response of the host cell, the latter being the focus of the present review.
Prospects for viruses infecting eukaryotic microalgae in biotechnology.

Temperature modulates immune gene expression in mosquitoes during arbovirus infection
- BiologyOpen Biology
Temperature significantly modulates mosquito gene expression in response to infection, potentially leading to impairment of immune defences at higher temperatures.
Potential Antiviral Action of Alkaloids
- Biology, ChemistryMolecules
Overall, the influence of alkaloids at the molecular level suggests a high degree of specificity which means they could serve as potent and safe antiviral agents waiting for evaluation and exploitation.
SARS-CoV-2 couples evasion of inflammatory response to activated nucleotide synthesis
- Biology, MedicineProceedings of the National Academy of Sciences of the United States of America
It is reported that SARS-CoV-2 couples evasion of inflammatory response to activated nucleotide synthesis, and inhibition of a key metabolic enzyme not only depletes the nucleotide pool but also restores host inflammatory defense, thereby effectively impeding Sars-Cov-2 replication.

Virus manipulation of cell cycle
Taking the maxim “Set a thief to catch a thief” as a counter strategy provides the very same virus evasion strategies as “ready-made tools” for the development of novel antivirus therapeutics.
Cytoplasmic Viruses: Rage against the (Cellular RNA Decay) Machine
- BiologyPLoS pathogens
This review describes the myriad ways that viruses deal with the general host RNA decay machinery that is active in the cell immediately upon viral infection—turning what, at first, appears to be very hostile territory for a foreign transcript into a sort of “promised land” for viral gene expression.
Adenovirus DNA replication.
- BiologyCold Spring Harbor perspectives in biology
The development of antivirals that interfere with human adenovirus replication and the impact of HAdV on human disease are covered.
The role of the influenza virus RNA polymerase in host shut-off
It is found that Pol II is ubiquitylated in influenza virus infected cells and ubiquitylation can be induced by the expression of the RNA polymerases, and that the viral RNA polymerase plays a critical role in this process.
Influenza Viruses and mRNA Splicing: Doing More with Less
The ability of IAV to be well adapted to the host’s splicing machinery is emphasized, and further investigations may contribute to a better understanding of splicing regulation with regard to viral replication, host range, and pathogenesis.
A Common Strategy for Host RNA Degradation by Divergent Viruses
- BiologyJournal of Virology
Multiple host shutoff factors have converged upon a common mRNA degradation pathway, and each targets translatable RNAs for cleavage and requires host Xrn1 to complete RNA degradation, although the mechanism of targeting and the position of the primary cleavage differ.
Converging Strategies in Expression of Human Complex Retroviruses
The present review summarizes the genetic organization and expression strategies of human complex retroviruses and highlights the converging mechanisms controlling their life cycles.
