Our new study reveals how bacterial toxins are physically captured through a sequential, concentration-dependent assembly mechanism before secretion via the T6SS. Fantastic collaboration with @fillouxlab.bsky.social. Congrats Patricia & Ambre for leading this work. Paper here: shorturl.at/O31Vn
Molecular basis of type VI secretion system effector loading - Nature Microbiology
Structural analysis reveals that the type VI secretion system effector cargo is enclosed within hexameric Hcp3 rings that form sequentially to enable effector loading and delivery by the Pseudomonas aeruginosa H3-type VI secretion system.

This paper started as an idea @albertomarina.bsky.social had many years ago… which of course means he was right all along 😄. Some of us just needed a few years (and a lot of experiments) to catch up. Grateful (and slightly humbled) to be part of this. Thanks Alberto! www.cell.com/cell/fulltex...
Phages communicate across species to shape microbial ecosystems
Gallego-del-Sol et al. show that arbitrium-coding phages can sense non-cognate peptide signals from other phages to regulate lysis-lysogeny decisions. This crosstalk affects lysis-lysogeny outcomes of...

The assembly of a hybrid type IV secretion system by a Crohn’s disease-associated Escherichia coli strain - Nature Communications
Adherent-invasive strains of E. coli are commonly isolated from patients with Crohn’s disease. Here, the authors show that an AIEC harbours a hybrid Type IV secretion system (T4SS) that mediates pilin...

Google's AI Co-Scientist Is Changing the Face of Scientific Research
Google's AI co-scientist is proving itself more than a novelty. In two biology studies, it generated exciting ideas that could have taken years of lab work to uncover.
