Subterranean Clover Stunt Virus Revisited: Detection of Two Missing Genome Components

open access: yesViruses, 2019
Subterranean clover stunt virus (SCSV) is a type species of the genus Nanovirus in the family Nanoviridae. It was the first single-stranded DNA plant virus with a multipartite genome, of which genomic DNA sequences had been determined.

Women in the European Virus Bioinformatics Center

open access: yesViruses, 2022
Viruses are the cause of a considerable burden to human, animal and plant health, while on the other hand playing an important role in regulating entire ecosystems. The power of new sequencing technologies combined with new tools for processing “Big Data”

Research Note: Characterization and phylodynamic analysis of new infectious bursal disease virus variants circulating in Argentina

open access: yesPoultry Science
: Infectious Bursal Disease is a highly contagious disease that affects young chickens and leads to significant economic losses. Its causal agent is a double-stranded RNA virus that, due to its high error rate during the replication process, gives rise ...

Viral Ancestors of Antiviral Systems

open access: yesViruses, 2011
All life must survive their corresponding viruses. Thus antiviral systems are essential in all living organisms. Remnants of virus derived information are also found in all life forms but have historically been considered mostly as junk DNA.

The mode and tempo of hepatitis C virus evolution within and among hosts

open access: yesBMC Evolutionary Biology, 2011
Background Hepatitis C virus (HCV) is a rapidly-evolving RNA virus that establishes chronic infections in humans. Despite the virus' public health importance and a wealth of sequence data, basic aspects of HCV molecular evolution remain poorly understood.

Viral Evolution and Adaptation as a Multivariate Branching Process

open access: yes, 2013
In the present work we analyze the problem of adaptation and evolution of RNA virus populations, by defining the basic stochastic model as a multivariate branching process in close relation with the branching process advanced by Demetrius, Schuster and ...

A two-step lyssavirus real-time polymerase chain reaction using degenerate primers with superior sensitivity to the fluorescent antigen test [PDF]

open access: yes, 2014
A generic two-step lyssavirus real-time reverse transcriptase polymerase chain reaction (qRT-PCR), based on a nested PCR strategy, was validated for the detection of different lyssavirus species.

Evolution and Epidemiology of Chikungunya Virus

open access: yes, 2016
Chikungunya is a mosquito-borne Alphavirus that is spreading worldwide in the tropical areas and that has a 11.8 kb RNA genome. The most relevant vectors belong to the genus Aedes and contribute to the diffusion of the three different genotypes of the virus from the original site of first identification in East Africa.

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.
