🚀New preprint from our lab!
I am very excited to finally share what has been the main focus of my PhD for the past almost 3 years! It is about viral dark matter and a powerful tool we built to shed light on it. 🧬💡

🚨Preprint alert - this is a big one! We transfer the revolutionary power of TnSeq to bacteriophages.

Our HIDEN-SEQ links the "dark matter" genes of your favorite phage to any selectable phenotype, guiding the path from fun observations to molecular mechanisms.

We built GenoPHI: a machine learning workflow that predicts phage-host interactions at strain level. This could help rapidly select phages to treat drug-resistant bacterial infections or for microbiome engineering without exhaustive lab testing.

I am so excited to share our project with you! We find prokaryotic proteases activate toxic enzymes and pores as a modular strategy in phage defense. We studied four fascinating protease-toxin pairs that are abundant across bacterial genomes:

Proteolytic activation of diverse antiviral defense modules in prokaryotes
Linked protease–effector modules are widespread in prokaryotic antiviral defense, yet the mechanisms of most remain poorly understood. Here we show that four of the most prevalent modules—metallo-β-la...

I’m excited to share my recent postdoc work. Here, we interrogate how different phage infection outcomes (productive vs. restrictive) affect the expression of phage defense systems. We find that a restricted infection not only inhibits the phage but also induces increased immune protein abundance.

Fascinating discovery - anti-phage defense protein is a proenzyme that is cleaved by partner protease after phage infection and all three! products of cleavage form active nuclease.
