Today in

, we highlight how a cousin of CRISPR-Cas10, mCpol, establishes an evolutionary trap in anti-phage immune systems. Check out

Our story describing the Panoptes bacterial immune defense system is now finally peer-reviewed and published today!

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.

Viruses are ubiquitous biological entities that exert immense selective pressures on their hosts, driving the evolution of diverse innate immune mechanisms across all domains of life. While innate imm...

📢 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 🧵 Preprint🔗:

Synthetically designed anti-defense proteins overcome barriers to bacterial transformation and phage infection
Bacterial defense systems present considerable barriers to both phage infection and plasmid transformation. These systems target mobile genetic elements, limiting the efficacy of bacteriophage-based t...
