The food contaminant deoxynivalenol activates the mitogen activated protein kinases in the intestine: Interest of ex vivo models as an alternative to in vivo experiments

► DON induces intestinal toxicity in a similar way in ex vivo and in vivo models. ► DON activates mitogen-activated protein kinases in both models. ► Jejunal explants are a useful model in intestinal toxicological studies.
