Thank you very much Nicola Diny and @jcb.org for highlighting our work on intestinal eosinophils ! 🙏

Spotlight @jcb.org: Nicola Diny @unibonn.bsky.social previews a study from @petrovalab.bsky.social et al. (rupress.org/jcb/article/...) which reveals that #eosinophils drive a developmental program for postnatal intestinal remodeling and maturation. rupress.org/jcb/article/... #Development

Happy to share scRNA-seq dataset of murine mesenteric tissue in easy-to-use format at the Single Cell Portal shorturl.at/mgQR9 Blood and lymphatic ECs, SMCs, fibroblasts, mesothelial cells from WT & Foxc2lecKO at single-cell resolution. Original publication: www.science.org/doi/10.1126/...

Our new paper is live ❣️🎉🎊

Irena Roci et al. @petrovalab.bsky.social 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. rupress.org/jem/article/... #lymphatics #AQP1

Calling all vascular biologists! Join us for cutting edge science at #Angioscience26 in gorgeous Seeon, Bavaria. Awesome speakers, intimate setting, many talks from abstracts. Deadline June 15th to register! vwfb.de/start/regist...

Our new paper is out!

#Eosinophils–usually linked to infection and disease–are actually helping to build the gut. New research from @petrovalab.bsky.social & Bernier-Latmani et al. shows they reprogram fibroblasts into villus smooth muscle cells, helping shape and mature the villi postnatally. rupress.org/jcb/article/...

Very happy to see our work on the cover of @jem.org 🤩

Thank you Luisa Iruela-Arispe and @jem.org for highlighting our work !

Rockefeller University Press@rupress.org · 4mo ago

Iruela-Arispe highlights @jem.org work by @petrovalab.bsky.social (rupress.org/jem/article/...) showing that endothelial cells actively regulate energy storage in white adipose tissue through MYCT1–IFITM2/3-dependent control of endolysosomal trafficking & mTORC1 signaling rupress.org/jem/article/...

‼️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 🚦 rupress.org/jem/article/... Work of two fantastic MD-PhD and PhD students Laureline Wetterwald and Anna Köck and many collaborators

Journal of Experimental Medicine@jem.org · 4mo ago

Wetterwald, Köck et al. @petrovalab.bsky.social report the existence of an endothelial metabolic checkpoint where MYCT1 restricts activity of IFITM2/3 to prevent energy waste at the vascular barrier and enable fat storage. rupress.org/jem/article/... 🎥 See video summary: youtu.be/SGZ-5GiZvrI

What a day! 🎉 Amazing science, keynotes by Hellmut Augustin & Bilal Sheik, and great energy at the SSMVR Annual Meeting! Congrats to poster & talk winners Anna Köck & Linh Tran! Huge thanks to president Britta Engelhardt for making SSMVR a success & welcome new president Andrea Banfi!

A recent preprint (Yang et al., doi.org/10.1101/2025...) challenges an article from my lab published in 2024 (Koh et al. 2024, PMID: 39537918). We strongly dispute their claims (please see our comment on bioRXiv). 1/4

Degeneration and Impaired Resilience of Skull Bone and Hematopoietic Bone Marrow

Bone marrow health is central to transplantations, blood formation, and cancer progression. However, the bone marrow niche deteriorates with age, impairing haematopoietic stem cell function. Contrary ...
