In this QBI fireside chat, Amber Smith, research specialist at UCSF and lead author of a Molecular Cell study, shares new insights into how HIV commandeers host cellular machinery to replicate.

In conversation with Zelda Love, HARC Program Manager at QBI, Amber walks through her team’s discovery of the cryo-electron microscopy (cryo-EM) structure of the HIV-1 Rev/RRE/CRM1/Ran complex—a critical assembly that enables viral RNA to exit the nucleus and continue the infection cycle. By visualizing this complex at near-atomic resolution, the team uncovered how HIV strategically hijacks host proteins to shuttle its genetic material out of the cell nucleus, a pivotal step in viral propagation.

Throughout the discussion, Amber breaks down the science behind the structure and explains why understanding these molecular interactions matters. Mapping this export mechanism not only deepens our understanding of HIV biology, but also reveals potential vulnerabilities that could inform future therapeutic strategies.

The conversation offers a look at the structural biology driving HIV research forward, and the collaborative effort behind uncovering the intricate tactics viruses use to survive.
