What if we could turn the tumor’s deadliest tricks against it?

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 out!
Together with @reneechang and the amazing @SorekLab , we explored viral sponges to map their diversity and function.
Discovered huge diversity, including sponges that inhibit Pycsar & Type IV Thoeris!

📢Preprint out!
Excited to share my final work from the @Soreklab!
We mined phage dark matter using structural features shared by anti-defense proteins (viral tools that help phages bypass bacterial immunity) to guide discovery.
Found 3 new families targeting immune signaling!
Genomes encode biological complexity, which is determined by combinations of DNA mutations across millions of bases
In new @arcinstitute work, we report the discovery and engineering of the first programmable DNA recombinases capable of megabase-scale human genome rearrangement
Excited to share our latest on the Type II Thoeris system! In collaboration with the Sorek and Kranzusch labs, we identify His-ADPR as a signaling molecule. Huge thanks to all involved—amazing teamwork!

Another cADPR isomer involved in bacterial immunity has been discovered. For me, N7 was the least expected position; I was sure it would be N3, but no... So, there are two more positions for cyclization that should be discovered: N3 and -NH2. More Thoeris systems are waiting! :)
Congrats our very own @Sys_Immunology member PI @TanaWein for the impressive new paper @Nature together with @SorekLab- Shedding yet another piece of the (inflammasome-related) origins of immunology in bacteria!! Proud of you Tana and team!

Now published @ScienceMagazine: TIR signaling activates caspase-like immunity in bacteria
We report a new immune molecule: N7-cADPR. Produced by phage-induced TIRs and activates a defensive bacterial caspase
Congrats @FrancoisRousset & @IlyaOsterman!

We just posted a new preprint where we found retrons in bacteria out in the real world, in dirt and water. We describe the first retrons in a handful of new species, show how they defend against phages, and use them to edit genomes. Read about it here: https://t.co/DiZmZOWCGs
Very happy our paper on CARD domains in gasdermin anti-phage defense systems is now published in @Nature 🥳 Thanks to all the people involved especially the Kranzusch lab and @SorekLab

Our paper out @Nature: CARD domains mediate anti-phage defense in bacterial gasdermin systems
CARDs are essential for caspase recruitment in inflammasome activation. We now find them in bacterial immune systems
Congrats @TanaWein! Thanks Kranzusch lab!

Thank you @theNASciences 🙏
It is an immense honor to be included in the same list as the giants in microbiology who received the Selman A. Waksman Award
We are honoring Rotem Sorek of @WeizmannScience with the 2025 Selman A. Waksman Award in Microbiology for groundbreaking discoveries on the immune system of bacteria. Congratulations! Learn about his research: https://t.co/CskDDISr5x #NASaward#microbiology
