‼️Fresh off the press‼️
In a nutshell: the IFITM2/3–MYCT1 complex is a new endothelial traffic controller deciding how much energy gets routed for storage in fat 🚦

Thank you very much Nicola Diny and @JCellBiol for highlighting our work on intestinal eosinophils !🙏
Spotlight: Nicola Diny @UniklinikBonn previews a study from @petrovalab et al. (hubs.la/Q04kvJwJ0) which reveals that #eosinophils drive a developmental program for postnatal intestinal remodeling and maturation. hubs.la/Q04ks9f70

Our new paper is live❣️🎊🎉🍾
Irena Roci et al. @PetrovaLab show that the water channel AQP1 sustains lymphatic endothelial cell migration under osmotic stress, establishing tissue #osmolarity as a key biophysical determinant of postnatal #lymphangiogenesis. hubs.la/Q04jyN2W0

Our new paper is out ! Congrats to @JBernierLatmani and the entire team!🎉🎉
#Eosinophils–usually linked to infection and disease–are actually helping to build the gut. New research from @PetrovaLab & @JBernierLatmani shows they reprogram fibroblasts into villus smooth muscle cells, helping shape and mature the villi postnatally. hubs.la/Q04ggV0t0

From breakthroughs in human genetics to strategies for drug delivery via and to the lymphatic system - last day at GRC Lymphatics 2026 was a blast!
Congrats to everyone for making this conference a success! 🙌
See you in 2028 as we pass the torch to @KarinaYaniv & Mark Kahn!

Wednesday - Day 4 of the GRC Lymphatics 2026!
More big topics on the table today:
- Lymphatics & cancer
- Immunological surveillance of tissues via lymph
- Lymphatic endothelium as active player in immunity
Lots of hard work ...and also a bit of play. 😄

🤩Two more exciting days at GRC Lymphatics 2026!
We’re exploring big questions:
-Developmental origins of lymphatics
-Lymphatic mechanotransduction
-Organ‑specific lymphatics and new therapies
Looks like an incubator for many new collaborations!

🎉 Huge congrats to Dr. Anna Köck on her successful PhD defense!
She uncovered a new protein complex that limits nutrient uptake by the endothelial barrier with implications for metabolism, obesity, and drug delivery. 🔥
One paper accepted, another coming soon: stay tuned! 🌟

Our new study is out! 🎉
Driven by MD-PhD Ludivine Bersier, our work shows how chemotherapy‑induced gut injury creates a systemic “chemomemory” that protects against colorectal cancer (CRC) liver metastasis.
