TWiV reviews a case of polio in Gaza, more Mpox, COVID-19 boosters, effectiveness of Ebola virus vaccine, measles cases across the US, an endogenous retroviral envelope protein that regulates human cardiomyocyte development, and submergence of…
TWiV explains how immune profiling was used to identify distinguishing features of Long COVID, and how a co-opted feline endogenous retroviral envelope promotes cell survival by controlling copper transport and homeostasis in cats.
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.
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.
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.
The TWiV team describes aphid control by using a viral capsid protein to deliver a spider toxin to plants, and a human endogenous retrovirus that enhances expression of a neuronal gene.
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.
