Virus-Cell Interactions | SpotlightThe Nucleolar Protein LYAR Facilitates Ribonucleoprotein Assembly of Influenza A VirusInfluenza A virus (IAV) must utilize the host cell machinery to replicate, but many of the mechanisms of IAV-host interaction remain poorly understood. Improved understanding of interactions between host factors and vRNP not only increases our basic knowledge of the molecular mechanisms of virus replication and pathogenicity but also provides insights into possible novel antiviral targets that are necessary due to the widespread...
GemThe RNA Epitranscriptome of DNA VirusesRNA modifications have generated much interest in the virology field, as recent works have shown that many viruses harbor these marks and modify cellular marks. The most abundant mRNA modification in eukaryotic cells, N6-methyladenosine (m6A), has been examined extensively at the genome-wide scale in both cellular and viral contexts.
GemDiscovering Invisible TruthsThe rise of populist movements worldwide is challenging science and motivating scientists to join the debate and enter politics. Based on my experience, taking a public stand will not come without slanderous personal and institutional attacks as an attempt to shake scientific credibility.
Vaccines and Antiviral Agents | SpotlightDevelopment of a Pan-H1 Influenza VaccineSeasonal influenza vaccines elicit strain-specific immune responses designed to protect against circulating viruses. Because these vaccines often show limited efficacy, the search for a broadly protective seasonal vaccine remains a priority. Among different influenza virus subtypes, H1N1 has long been circulating in humans and has caused pandemic outbreaks. In order to assess the potential of a multivalent HA combination vaccine to...
Structure and AssemblyA Proteomic Atlas of the African Swine Fever Virus ParticleAfrican swine fever virus causes a highly contagious and lethal disease of swine that currently affects many countries of sub-Saharan Africa, the Caucasus, the Russian Federation, and Eastern Europe and has very recently spread to China. Despite extensive research, effective vaccines or antiviral strategies are still lacking, and many basic questions on the molecular mechanisms underlying the infective cycle remain. One such gap regards...
Virus-Cell Interactions | SpotlightDynamin-Like Proteins of Endocytosis in Plants Are Coopted by Potyviruses To Enhance Virus InfectionIt is well known that animal viruses enter host cells via endocytosis, whereas plant viruses require physical assistance, such as human and insect activities, to penetrate the host cell to establish their infection. In this study, we report that the endocytosis pathway is also involved in virus infection in plants. We show that plant potyviruses recruit endocytosis dynamin-like proteins to support their infection. Depletion of them by...
Virus-Cell Interactions | SpotlightNovel Class of Viral Ankyrin Proteins Targeting the Host E3 Ubiquitin Ligase Cullin-2Viruses encode multiple proteins aimed at modulating cellular homeostasis and antagonizing the host antiviral response. Most of these genes were originally acquired from the host and subsequently adapted to benefit the virus. ANK proteins are common in eukaryotes but are unusual amongst viruses, with the exception of poxviruses, where they represent one of the largest protein families. We report here the existence of a new class of...
