Congrats! Beautiful work

Divergent viral phosphodiesterases for immune signaling evasion Cyclic dinucleotides (CDNs) and other short oligonucleotides play fundamental roles in immune system activation in organisms ranging from bacteria to humans. In response, viruses use phosphodiesterase...

Excited to share our new preprint co-led by @jnoms.bsky.social!

Here we reveal an exceptional diversity of viral 2H phosphodiesterases (PDEs) that enable immune evasion by selectively degrading oligonucleotide-based messengers. This 2H PDE fold has evolved striking substrate breath & specificity.

Recurrent acquisition of nuclease-protease pairs in antiviral immunity Antiviral immune systems diversify by integrating new genes into existing pathways, creating new mechanisms of viral resistance. We identified genes encoding a predicted nuclease paired with a trypsin...

Excited to finally share this work!
We noticed a pair of genes - a nuclease and a protease - shuffles between antiviral systems. We show how proteolysis activates the nuclease, triggering defense in known and unknown immune contexts.
