Proud to share my first first-author article from my PhD!
A big thank to my chiefs @thicoz.bsky.social @cascaleslab.bsky.social and congratulations to all co-authors @audebertstephane.bsky.social @Caterina comas
Very happy to see the second story from my PhD out in @currentbiology.bsky.social
An exciting project where we explored the roles of secretion systems and gliding motility in predatory behavior in F. johnsoniae.

Amazing science at the 2nd edition of the Secretion Days in Marseille 🌞 ! Huge thanks to all participants and to @archaellum.bsky.social for an outstanding opening talk. Looking forward to the next edition!

Our paper on how a conveyor belt-associated protein of T9SS-driven gliding bacteria acts as a molecular switch, reversing T9SS rotation to fine-tune movement - like a smart conveyor or biological snowmobile adapting to changing terrain is out now in @mbio.bsky.social journals.asm.org/doi/10.1128/...
Paillat et al. show that Flavobacterium johnsoniae combines type VI and type IX secretion
systems with gliding motility to efficiently kill diverse bacterial competitors. They
demonstrate that nutrien...
The T6SS is a widespread nanoweapon deployed by #bacteria, but why is it deployed heterogeneously? @cascaleslab.bsky.social &co show that #Ecoli adopt distinct #T6SS attacker "ON" & defender "OFF" roles to optimize survival, a key strategy in microbial warfare @plosbiology.org 🧪 plos.io/3S5dL45
