Sean Whelan returns to TWiV to speak with Vincent about using haploid cell lines to identify genes encoding cell receptors for viruses, including Ebolavirus, Lassa virus, and more.
The TWiV posse considers viral insulin-like peptides encoded in fish genomes, and antiviral immunity in insects by production of viral DNA from defective genomes of RNA viruses.
The TWiVumvirate discuss the giant Tupanvirus, with the longest tail in the known virosphere, and dampened STING dependent interferon activation in bats.
Vincent and the Virals review undermining of antiviral effectiveness by genital inflammation, and heterogeneity of influenza virus infection in single cells.
The TWiV Masters discuss serologic evidence of Ebolavirus infection in a population with no outbreaks, and the set of endogenous viral elements in the mosquito genome.
The TWiVodrome considers the intestinal tract as an alternative infection route for MERS coronavirus, and how reduced accumulation of defective viral RNAs might lead to severe influenza.
Scott Hensley joins the TWiVites to review the current influenza season and presence of the virus in exhaled breath of symptomatic cases.
The TWiVome explores induction of antiviral responses by repeating patterns of capsids, and a fungus in the mosquito gut that aids dengue virus replication.
The TWiV team explains how infectious horsepox virus – likely the ancestor of smallpox vaccines – was recovered from chemically synthesized DNA fragments.
The TWiVodrome explains how a gag-like protein from a retrotransposon forms virus-like particles that carry mRNA within vesicles across the synapse.
