A massive expansion of Thoeris defense systems !

Congrats @erezyirmiya.bsky.social and @soreklab.bsky.social
I’m happy to share our new preprint! We uncovered the full diversity of bacterial TIR-based antiviral immune signaling, massively expanded the known diversity of Thoeris systems, and revealed conservation of TIR-derived immune signals across the tree of life.

Preprint: Systematic discovery of TIR-based immune signaling systems in bacteria

Conservation of TIR-derived signals accross the tree of life! We found bacterial TIR immune systems that signal via canonical cADPR (like in humans) and 2'cADPR (a plant immune signal).

Documented 11 Thoeris types

Incredible to learn how far-reaching and diverse Thoeris really is! TIRs play key roles across kingdoms, and this work beautifully highlights their bacterial origins.

Such a beautiful and well-rounded discovery, yet another exciting strategy in bacterial immunity. Congrats, Ilya!
Bacteria can sense when a virus starts shredding their genome — by detecting methylated mononucleotides.

Preprint: De-novo design of proteins that inhibit bacterial defenses

Our approach allows silencing defense systems of choice. We show how this approach enables programming of “untransformable” bacteria, and how it can enhance phage therapy applications

Excited to share my final work from the @soreklab.bsky.social!

We mined phage dark matter using structural features shared by anti-defense proteins (viral tools that help phages bypass bacterial immunity) to guide discovery.

This was our latest journal-club paper. Nice use of large-scale AlphaFold modelling & various experiments. Phage proteins’ ability to recognise eukaryotic homologues of their bacterial targets is striking - suggests these proteins evolved to recognise their targets in a fairly mutation-resistnt way.

Remarkable that phage proteins can inhibit human and plant TIR proteins and human cGAS. Conservation of function across such long evolutionary distances identifies new immunomodulators

Congrats to @soreklab.bsky.social and Kranzusch labs! What a great collaboration that is 😍
