Brianne joins the TWiVMasters to explain how mutations in genes encoding RNA polymerase III predispose children to severe varicella, and detection of an RNA virus by a DNA sensor.

Sharon and Scott return to TWiV for a Zika virus update, including their work on viral evolution and spread, and whether pre-existing immunity to dengue virus enhances pathogenesis.

Lynda Coughlan joins the weekly virtual bus companions for a discussion of a host defense peptide from frogs that destroys influenza virus, and mouse models for acute and chronic hepacivirus infection.

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 glorious TWiVerati un-impact their email backlog, anwering questions about viruses, viruses, viruses, viruses, viruses, and more. You should listen – our fans ask great questions!
