TWiV covers a study of SARS-CoV-2 persistence at multiple sites in the human body, and the role of endogenous retroviruses in ageing and senescence.
Cedric and John join TWiV to discuss their research showing that a human protein derived from an ancient retrovirus infection can protect against infection by other retroviruses. Hosts: Vincent Racaniello, Rich Condit, and Kathy Spindler Guest:…
Vincent travels to Cornell University to speak with Cedric about his career and his research on mobile genetic elements such as transposons and endogenous viruses and how they have shaped the evolution of nearly all organisms.
The Team with Invincible Values discusses whether dogs or cats passively carry SARS-CoV-2 on hair and foot pads, maternal to fetal transfer of antibodies in infected or vaccinated pregnant women, and evidence that retroviruses infected cetaceans before and after they moved into the oceans.
The League of Extraordinary Virologists celebrate the eradication of wild poliovirus type 3, and consider the effectiveness of an influenza vaccine produced in insect cells, and how small RNAs are protecting the Koala germline from retroviral invasion.
The TWiV team reveal the origin of the poxvirus membrane, and how a retrovirus drove the development of the placenta of a lizard.
Paul Bieniasz joins the TWiV team to talk about the co-option, millions of years ago, of an endogenous retrovirus envelope protein by hominid ancestors for host defense against viral infection.
Ted and Welkin inform the TWiV team how the evolution of ancient retroviruses can be inferred by their sequences in the genomes of modern mammals, and join in a discussion of virus dispersal during different methods for drying hands.
Vincent speaks with John Coffin about his career studying retroviruses, including working with Howard Temin, endogenous retroviruses, XMRV, chronic fatigue syndrome and prostate cancer, HIV/AIDS, and his interest in growing cranberries.
Vincent, Alan, and Kathy reveal how a retrovirus in the human genome keeps embryonic stem cells in a pluripotent state, from where they can differentiate into all cells of the body.
