Most people associate viruses with illness and suffering, however, considering that the vast majority of viruses cause no illness and are actually beneficial to humans and the planet as a whole, this sentiment is largely misplaced.
by Gertrud U. Rey Herpes simplex viruses establish lifelong persistent infection in sensory neurons of infected individuals, a phenomenon called latency. Latent viral genomes are “dormant” but can sporadically reactivate and begin replicating in a phase called lytic replication, which is often accompanied by shedding of virus particles and the appearance of painful lesions. There …
by Gertrud U. Rey Bacteria use at least a couple of pathways for protecting themselves against viral infection. In return, multiple viral strategies for inhibiting or evading these pathways have evolved.

On episode #382 of the science show This Week in Virology, Nels Elde and Ed Chuong 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.
