Deltaviruses spread through a viral Trojan Horse Hepatitis D-like satellite viruses, known as deltaviruses, have been recently discovered in a wide range of animals. These viruses are thought to expr…

We found a viral Trojan Horse: a virus can hide inside another virus.This one surprised us: deltaviruses don’t just borrow a helper virus. They can travel inside it.
A literal Trojan Horse “virus-in-a-virus” route into cells. 🤯 Kudos to 1st author @viroscope.bsky.social and co-authors !

Thank you for having me!!

Wonderful to host @jonathonmifsud.bsky.social at UQ today for the SCMB Seminar Series. An excellent journey using protein structural information to study viral evolution across deep time, including new insights into the evolutionary history of Flaviviridae (RIP) and viral membrane fusion mechanisms.

APSPM brought together researchers from around the world to explore protein evolution from different angles. Structural approaches are reshaping evolutionary inference and the community is growing. Huge thanks to participants and @official-smbe.bsky.social for making this meeting a success.

What a great conference!! Leaving Brisbane inspired about the future of structural phylogenetics!

Thanks again to the organisers @cpuentelelievre.bsky.social @proteinmechanic.bsky.social and Jordan Douglas for an amazing work putting it all together!

Our discovery of novel viruses in invasive camelids in Australia leads us to propose a simple idea: RNA viruses may repeatedly evolve functional modules at the 5′ end of their genomes.

An interesting way to look at encoded structural characters to build alignments and trees downstream. This takes structural phylogenetics one step further in the post-AlphaFold era.
