The orphan receptor GPR84 drives inflammation in Buruli ulcer development The GPR84 orphan receptor is a regulator of inflammation and a candidate therapeutic target in Buruli ulcer.

📣 After 5 years, the last paper from my PhD is finally out in #ScienceTranslationalMedicine!

We show that sustained tissue inflammation drives disease progression in #Buruliulcer. And targeting it alongside antibiotics can accelerate healing.

📣 Happy to share our new chapter in Live Biological Imaging Across Scales! We discuss how to explore membrane damage responses using Dicty and high-throughput single-cell analyses 👀. Shout-out to @angieprrt.bsky.social and the team onlinelibrary.wiley.com/doi/10.1002/...

All currently approved antibiotics inhibit essential cellular processes. Ever wonder if we could kill bacteria using the opposite strategy?

Here, we demonstrate an alternative antibacterial strategy: lethality through pathway over-activation.

🚨 New preprint!

Together with @carobarisch.bsky.social lab, we investigated how intracellular compartmentalization shapes lipid acquisition in mycobacteria

Interestingly, deleting one FACL enzyme (FACL6) revealed striking compartment-dependent phenotypes 🔬

Check it out: doi.org/10.64898/202...

🎉 Big news! Last Saturday, Thierry was awarded the Egon Naef Foundation Prize for in vitro research 🏆 A wonderful recognition of his innovative work throughout his career developing alternatives to animal testing 👏

🚨 Preprint alert 🚨

In this study, we reveal how a calcium-sensing protein coordinates membrane damage sensing with repair pathways in response to damage from intracellular mycobacteria

Huge congrats to @guallar-garrido.bsky.social for leading this project! 🤩👏

A long journey with a fantastic conclusion! Congrats 🍾🧑‍🎓

🇻🇳 What a great week at the BPHCI Conference in Vietnam! @j-toinon.bsky.social and @angieprrt.bsky.social enjoyed sharing their results on M. marinum–Dicty interactions. A small crowd, but packed with brilliant science and great vibes! 🥂

Inorganic sulfate is critical for Mycobacterium tuberculosis lung tissue colonization and redox balance | PNAS Tuberculosis remains the deadliest infectious disease caused by a single pathogen, highlighting the urgent need for novel therapies. A deeper under...

Excited to share Wendy Le Mouëllic’s PhD work, now published in @pnas.org!
It reveals that M. tuberculosis depends on inorganic sulfate import to survive inside host cells—fueling essential processes such as redox balance and stress resistance.
Huge congrats to Wendy & colleagues!
