Viruses (like HIV) and their hosts (like humans) are locked in an evolutionary arms race, with each trying to outwit the other. But viruses seem to have a big advantage (MUCH faster evolution), so how can the slowly evolving human arsenal keep pace? On this episode of the Bio Eats World Journal Club, host Lauren Richardson (@lr_bio) talks to Professor Harmit Malik (@HarmitMalik) about new research from his lab determining some surprising characteristics of human antiviral proteins that allow them to persevere in this evolutionary fight and how this information could be used to develop new, possibly curative, treatments for HIV. Harmit Malik, PhD (Professor and Associate Director of the Basic Sciences Division at the Fred Hutchinson Cancer Research Center) joins host Lauren Richardson to discuss the results and implications of the article "Mutational resilience of antiviral restriction favors primate TRIM5α in host-virus evolutionary arms races", by Jeannette L Tenthorey, Candice Young, Afeez Sodeinde, Michael Emerman, and Harmit S Malik,  published in eLife.
