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 TWiVumvirate reviews this years crop of Nobel Prizes, and how cells prevent leakage of mitochondrial double-stranded RNA into the cytoplasm, which would otherwise lead to the production of interferon.

Ben tenOever joins the TWiVoli to discuss the evolution of RNA interference and his lab’s finding that RNAse III nucleases, needed for the maturation of cellular RNAs, are an ancient antiviral RNA recognition platform in all domains of life.

The TWiVsters explore mutations in the interferon pathway associated with severe influenza in a child, outbreaks of avian influenza in North American poultry farms, Ebolavirus infection of the eye weeks after recovery, and Ebolavirus stability on surfaces and in fluids.
