    HIF transcription factors, central mediators of cellular adaptation to critically low oxygen levels (=hypoxia), have been largely studied for their crucial role during cancer development. We unveiled two new major roles of HIF. First, in innate immunity and infection, we demonstrated the key contributions of HIFs in regulating important immune effectors molecules. Second, we highlighted the role of HIFs in iron metabolism as critical regulators of iron absorption in the intestine and in systemic iron homeostasis by regulating the liver synthesis of the iron regulatory hormone, hepcidin.
