Yersiniabactin Siderophore of Crohn's Disease-Associated Adherent-Invasive Escherichia coli Is Involved in Autophagy Activation in Host Cells.

Our study highlights a novel role for yersiniabactin siderophore in AIEC-host interaction. Indeed, yersiniabactin, which is an advantage for AIEC to growth in a competitive environment, could be a disadvantage for the bacteria as it activates autophagy, a key host defense mechanism, leading to bacterial clearance.
