The gut insulin receptor acts as gatekeeper of intestinal barrier integrity

Florian Sicherre, Dalale Gueddouri, Michèle Caüzac, Adele Caudron-Hedeline, Fadila Benhamed, Wafa Charifi, Benoît Terris, Benoît Chassaing, Lucie Beaudoin, Matthieu Rouland, Angela Bosh, Claudia Cavelti‐Weder, Gunter Leuckx, Yves Heremans, Agnès Lehuen, , Sandra Guilmeau

This study shows that gut insulin receptor loss increases intestinal permeability and susceptibility to infections by impairing Paneth cell function and intestinal stem cell homeostasis.
