Preprint: Bacteria sense virus-induced genome degradation via methylated mononucleotides

tinyurl.com/ch3damp

We show how molecular byproducts released during virus-induced cell exploitation are used as signals to trigger host immunity

Revealed by the amazing Ilya Osterman. See his thread below👇

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 👇

"We need more institutional experiments for science" makes sense to me @seemaychou.bsky.social. We might not like some of 'em and some'll fail, but given academic science often looks like a feudal system needing an industrial revolution trying things can't hurt.. seemay.substack.com/p/big-experi...

Panoptes guards the CBASS pathway (bacterial cGAS-STING). One facet of this work that I find particularly exciting is the genetic linkage between Panoptes and CBASS, which significantly co-occur in bacterial genomes. What other phage defense systems may be genetically (and functionally) linked?

Our work on the Panoptes antiphage system is published! Here we find that Panoptes "watches" the cytosol for phage immune evasion proteins–captured in this illustration by Clair Huffine of Insight Illustrations. A beautiful example of the effector triggered immunity paradigm.
