TWiV is a weekly netcast about viruses - the kind that make you sick. Professors Vincent Racaniello, Dickson Despommier, Rich Condit, Kathy Spindler and science writer Alan Dove and guests deconstruct viruses, how they cause illness, and dissect the latest research.

    Tuesday two: SARS-CoV-2 and TLR2

    Tuesday two: SARS-CoV-2 and TLR2

    TWiV discusses the finding that the envelope (E) protein of SARS-CoV-2 is sensed by toll-like receptor 2 on cells, leading to the production of inflammatory cytokines that cause damage to cells and tissues in COVID-19.

    Sputnik spat and furin in ferrets

    TWiV examines the claim by Brazil’s ANVISA that the Sputnik vaccine contains replication-competent adenovirus, and a role for the furin cleavage site in SARS-CoV-2 spike for efficient reproduction in the respiratory tract, evasion of antiviral IFITM proteins, and transmission in ferrets.

Superb except for Amy Rosenfeld

Every regular members are great to listen to except for Amy Rosenfeld. It’s not her voice but the way she speaks (semi-vocal fry) that gives my ears aural COVID-19.

Thank you for such an information packed podcast!

Absolutely love your all your podcasts! You all do such an excellent job of making science even more fascinating. Kudos & thanks for all the time devoted to every show!

Paulie, too. ,

Listen to this Podcast

TWIV is a reminder of all that is potentially great about the internet. Not only is Racaniello a world class virologist, he also happens to be a naturally great teacher (I am not his student). The rapport between the regular panelists is engaging and pleasant. The guests are at the cutting edge of the science. Intereated listeners should check out his virology course on You Tube. It's fantastic and free!
