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.
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.
The complete TWiV crew teams up with Welkin Johnson to explore the other AIDS epidemic, infection of monkeys with simian immunodeficiency virus, and its restriction by the cellular protein TRIM5.
Vincent, Alan, and Rich answer listener questions about lab procedures, prokaryotes, endogenous retroviruses, the iPad and teaching, prions, mimivirus, splitting water with viruses, and the polio outbreak in Tajikistan.
