Happy to share our new preprint describing prophage encoded anti-phage defense system,TERi, that targets the terminase complex of invading phages to inhibit DNA packaging. The system also encode self immunity proteins that protect the prophage.

Our paper out @CellCellPress: Structure-guided discovery of viral proteins that inhibit host immunity
Congrats @ErezTzvi, Azita Leavitt, @amitai_gil, our collaborators @ Kranzusch lab, and coauthors

Did you know that bacteria remember their past for many generations? In this new preprint from us (@VillaniAlexis and Senen Mendoza) and Banin lab (@ShmidovE ), we reveal the "how?" and "why?" underlying a long-standing mystery in bacterial memory. biorxiv.org/content/10.110…
Preprint alert 🚨! I present you the second and final manuscript on the BASEL phages! 36 new deeply characterized phages from viral groups that were so far mostly terra incognita - and all infect the E. coli K12 lab strain with easy tricks. 1/12

A nice little highlight here in @NatureRevMicro by @cazares_adr and team on our work (+ from the Dechesne lab) rediscovering plasmid-dependent phages!
A hundred or so are known (most isolated in the last few years!) and we've only scratched the surface 👀 nature.com/articles/s4157…
Latest from the lab! PICI and prophage-encoded Tai proteins protect cells by blocking phage tail assembly. Prophages counter with a mechanism allowing tail formation after induction. Defence and counter-defence genes are organised for expression. nature.com/articles/s4146…
🚨 It's out!: There's a new toxin in town.. Chelona Toxin—a promising alternative to diphtheria toxin for targeted drug delivery that bypasses pre-existing antibodies, boosting efficacy and safety for next-gen therapeutics. 🧬 @EmboMolMedembopress.org/doi/full/10.10…
Out today in @Nature!
I am thrilled to share our work on the PARIS immune system in its final published form. Huge thanks to my mentor, Kevin Corbett @_KevinCorbett, and my teammates.
See the thread below in comment section for a quick summary!

Thrilled to share the final version of my postdoc project, out today in @Nature!
We investigated the Bil system – a ubiquitin-like antiphage defense system – and discovered a new defense mechanism!

We found an anti-CRISPR that pulls apart a type I-F CRISPR-Cas complex by binding to the Cas7 subunits and extracting them one at a time. Big Congrats!! to my pdf Chantel Trost who did most of the work.
Check out the latest story from the Sternberg group: phages coopted transposon-encoded nucleases (TnpB) and repurposed them for regulation of host genes!

Thrilled to see this work in print, & a huge thanks to my amazing co-authors!!
A picture is worth 1536 plaque assays. While we used a robot, we also tried a dirt-cheap 3D-printed alternative which works wonders at 384-density. I really believe this pre-print has the potentially to be the largest impact I will make on my field.

Excited to share my preprint from @aaronwhiteley lab showing how a bacterial NLR-related protein detects phages through the host chaperone DnaJ! This is one of the few ssRNA phage defense systems identified, and we found an interesting detection mechanism
