Phage SSB detection by retron Eco8 msDNA unleashes nuclease-mediated immunity The cryo-EM structure of the retron Eco8 system reveals an autoinhibited 4:4:4 complex of RT, msDNA, and OLD nuclease. Phage SSB binding to msdDNA unleashes non-specific nuclease activity to restrict phage replication, establishing msDNA as a molecular switch for Eco8 activation.

Disassembly activates Retron-Septu for antiphage defense - PubMed Retrons are antiphage defense systems that produce multicopy single-stranded DNA (msDNA) and hold promises for genome engineering. However, the mechanisms of defense remain unclear. The Retron-Septu system...

A DNA-gated molecular guard controls bacterial Hailong anti-phage defence - Nature Nature - A DNA-gated molecular guard controls bacterial Hailong anti-phage defence

Excited to share my PhD work in the Kranzusch Lab published in @nature.com!

Two key discoveries:
- Nucleotides can act as negative regulators of antiviral immunity
- Ion channel activation is gated by DNA

Thank you to our all collaborators! @soreklab.bsky.social
