Raul Andino joins Vincent and Amy to talk about the finding that a cricket paralysis virus protein restricts RNA-based immunity in insects by regulating the activity and stability of the Argonaute protein.
At the University of Zürich, Vincent speaks with virologists Cornel Fraeful, Urs Greber, and Silke Stertz about their careers and their work on AAV2, adenovirus entry, and influenza virus.
The TWiVsters review isolation of a naturally occurring DNA virus from fruit flies, and the cell-type specific function of a small transmembrane protein encoded in an open reading frame upstream of the enterovirus polyprotein.
Team TWiV cover the discovery of another giant virus from 30,000 year old Siberian permafrost, and how viral aggregation accelerates the production of new infectious viruses and increases fitness, demonstrating an Allee effect.
The TWiVidae review universal influenza vaccines that are in clinical trials, and discovery of an atypical parvovirus that causes chronic kidney disease in middle aged, immunocompromised laboratory mice.
The TWiVomers review a potential role for herpes simplex virus type 1 as a cause of Alzheimer’s Disease, including the finding that amyloid-beta acts as an antiviral by enveloping virus particles.
Vincent travels to Penn State College of Medicine in Hershey, PA to speak with Nick and Leslie about their careers and their work on human cytomegalovirus and retroviruses.
Brianne and Vincent tackle two studies that utilize infectious viruses to examine zoonotic potential of Bombali virus, a new ebolavirus from an insectivorous species in Sierra Leone, and a human mumps-like virus from an African flying fox in DRC.
Lonya and Jeremy take the TWiV team beTWIXt primate immunodeficiency virus proteins Vpx and Vpr and how they counteract transcriptional repression of proviruses by the HUSH complex.
The TWiV team notes the passing of Tom Steitz, an outbreak of acute flaccid myelitis in the US, a continuing Ebola virus outbreak in DRC, respiratory vaccinia due to inhalation of ground up rabbit skin, and how a human papillomavirus capsid protein directs virus-containing endosomes towards the nucleus.
