Don’t miss next @evborg.bsky.social workshop!
Thank you Luisa Iruela-Arispe and @jem.org for highlighting our work !
‼️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 🚦

Work of two fantastic MD-PhD and PhD students Laureline Wetterwald and Anna Köck and many collaborators
Very happy to see our work on the cover of @jem.org 🤩

#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/...
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/...

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/...
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
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/...
