sécrétion pathway
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.

Type VI and type IX secretion systems and gliding motility contribute to facultative predation by Flavobacterium johnsoniae
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...

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

A molecular conveyor belt-associated protein controls the rotational direction of the bacterial type 9 secretion system | mBio
The type 9 secretion system (T9SS) is fundamental to bacterial gliding motility, pathogenesis, and surface colonization. Our findings reveal that the C-terminal region of the conveyor belt-associated ...

Thrilled to share our new paper in
@science.org
describing our discovery that bacteria can switch from competitors to bonafide predators when resources run dry—arming nanoscale “spears” (T6SS) to stab & consume neighbours.

Antagonism as a foraging strategy in microbial communities
In natural habitats, nutrient availability limits bacterial growth. We discovered that bacteria can overcome this limitation by acquiring nutrients by lysing neighboring cells through contact-dependen...
