TWiV describes how a viral capsid protein activates a bacterial innate immune system that interferes with protein synthesis, and human-associated redondoviruses that infect the commensal protozoan Entamoeba gingivalis.
TWiV discusses genetic evidence of susceptible wildlife in SARS-CoV-2 positive samples at the Huanan Wholesale Seafood Market, polio cases in African linked to a new polio vaccine that was designed to not cause the disease, and structural conservation of hepatitis B virus capsid proteins over millions of years despite a shift from a naked to an enveloped capsid.
From the NIH campus (recorded February 2020) Vincent and Rich meet with Eugene Koonin to discuss his theories on the evolutionary origins of viruses.
TWiV provides updates on the new coronavirus causing respiratory disease in China, the current influenza season, and the epidemic of African swine fever, including determination of the three-dimensional structure of the virus particle.
The TWiVome explores induction of antiviral responses by repeating patterns of capsids, and a fungus in the mosquito gut that aids dengue virus replication.
From Indiana University, Vincent and Kathy speak with Tuli Mukhopadhyay, John Patton, and Adam Zlotnick about their careers and their work on alphaviruses, hepatitis B virus, and rotaviruses.
The TWiVeroos deliver the weekly Zika Report, then talk about a cryoEM structure of a plant virus that reveals how the RNA genome is packaged in the capsid, and MIMIVIRE, a CRISPR-like defense system in giant eukaryotic viruses.
Two Coynes join the TWiV overlords to explain their three-dimensional culture model of polarized intestinal cells for studying enterovirus infection.
The TWiVniks discuss the structure of a virus that reproduces in an extreme environment, long-term consequences of Ebolavirus infection, and VirScan, a method to identify the different virus infections you have had in your lifetime.
The TWiV team describes aphid control by using a viral capsid protein to deliver a spider toxin to plants, and a human endogenous retrovirus that enhances expression of a neuronal gene.
