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.
TWiV 781: My genome is left to tell the tale

- Tagged as: antibodies, cat, cetaceans, COVID-19, dog, endogenous retrovirus, evolution, fetus, IgG, pandemic, pregnant women, provirus, retrovirus, SARS-CoV-2, transplacental passage, Vaccine, viral, virology, virus, viruses
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.
TWiV 571: Piwi koalas

- Tagged as: baculovirus, endogenous retrovirus, Flu, Flublock, Flucelvax, germline, HA, influenza, influenza vaccine, insect cell, Koala, Koala retrovirus, piRNA, transposon, viral, virology, virus, viruses
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.
TWiV 439: The purloined envelope
- April 30, 2017
- Tagged as: endogenous retrovirus, envelope protein, erv, exaptation, gammareterovirus, HERV-T, hominid, MCT-1, Paul Bieniasz, retrovirus, viral, viral receptor, virology, virus, viruses
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.
Vincent, Alan, and Welkin discuss how endogenous retroviruses in mice are held in check by the immune response.
Vincent, Alan, Dickson and Rich answer listener questions about XMRV, yellow fever vaccine, virus-like particles, West Nile virus, amyotrophic lateral sclerosis and human endogenous retroviruses, multiplicity of infection, and how to make a poxvirus.
