When I first entered the field of virology, in the 1970s, the definition of virus included the then-correct observation that no viral genome encoded any part of the translational apparatus. This dictum was shattered by the discovery of giant viruses which were found to encode tRNAs, aminoacyl tRNA syntheses, and many proteins involved in translation. …
The TWiV team discuss the use of quantum dots to study uncoating of influenza virus in real time, and induction of endothelial dysfunction by flavivirus NS1 proteins in a tissue-specific manner.

Virus particles are metastable: they must be highly stable, to protect the nucleic acid while traveling from host to host or cell to cell, and then come apart to liberate the genome into the cell. New insight into this uncoating process comes from beautiful images of feline calicivirus showing formation of a portal on the …
The TWiV crew reveal a unique portal on the calcivirus capsid formed upon receptor engagement, and the regulation of interferon responses in virus-infected cells by methylation of mRNA.

The gut tracts of many animals are inhabited by a microbial community composed of bacteria, archaea, fungi, and viruses. The interplay among these inhabitants can have an impact on health and disease. Mosquitoes are no exception – replication of dengue virus in the gut tract is modulated by a fungus and a bacterium.
