An incredible story revealing a novel defense system that senses DNA shredding during phage infection — beautifully solved by @ostermanilya.bsky.social ! 🧬✨
Bacteria can sense when a virus starts shredding their genome — by detecting methylated mononucleotides.
Here’s the story of how we discovered the Metis defense system 👇

Our story describing the Panoptes bacterial immune defense system is now finally peer-reviewed and published today! www.nature.com/articles/s41...
The Panoptes system uses decoy cyclic nucleotides to defend against phage - Nature
The Panoptes antiphage system defends bacteria by detecting phage-encoded counter-defences that sequester cyclic nucleotide signals, triggering membrane disruption and highlighting a broader strategy of sensing immune evasion through second-messenger surveillance.

Effector-triggered immunity (ETI) indirectly detects pathogen effector activity on the host cell.
Kevin Barthes,Tanita Wein and I examine how prokaryotic and eukaryotic viruses deploy similar effectors that activate ETI, underscoring its central role across the tree of life.

📢 New preprint alert!
We designed synthetic proteins that can block bacterial immune systems, allowing phages + plasmids to overcome natural defenses.
This could transform phage therapy + genetic engineering.
Here’s what we found 🧵
