At Retroviruses 2019 in Cold Spring Harbor, Vincent speaks with virologist Bryan Cullen about his work and his career, together with former associates Ann Skalka, Paul Bieniasz, and Michael Malim.
Steve Goff returns to TWiV to discuss the work of his laboratory on how retroviral genomes are silenced in infected cells.
Vincent travels to Penn State College of Medicine in Hershey, PA to speak with Nick and Leslie about their careers and their work on human cytomegalovirus and retroviruses.
Vincent and Dickson travel to the 44th Retrovirus meeting at Cold Spring Harbor Laboratories, where they speak with John Coffin, Stephen Hughes, Ya-Chi Ho, and Matt Takata about the meeting and their work on HIV-1.
The TWiVodrome explains how a gag-like protein from a retrotransposon forms virus-like particles that carry mRNA within vesicles across the synapse.
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.
Trudy joins the the TWiVlords to discuss new tests for detecting prions in the blood, and evidence showing that foamy retroviruses originated in the seas with their jawed vertebrate hosts at least 450 million years ago.
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.
Nels and Ed join the TWiV team to talk about their observation that regulation of the human interferon response depends on regulatory sequences that were co-opted millions of years ago from endogenous retroviruses.
