Viruses have parasites too. Our new preprint shows how phages use VIPR to silence parasitic satellites, and how the satellites fight back with its own decoy VIPR RNAs that redirect VIPR to DNA REP elements in the host genome!! www.biorxiv.org/content/10.6...

A new preprint by @amirfromm.bsky.social 📣 How do protists fight viruses in nature? Using single-cell sequencing in an isolated alpine lake, we uncover natural giant-virus infections and reveal the induction of viperin, an ancient antiviral defense, in wild protists 🏔️🦠->

1/1 How does a single methyl group activate bacterial defence? In my PhD work with @matthiaswilmanns.bsky.social and @typaslab.bsky.social, we reveal how this tiny DNA modification triggers retron disassembly and toxin activation. Now on bioRxiv: www.biorxiv.org/content/10.6...
