Cell-cell junctions, epithelial barrier function and inflammation in intestine: an emerging role for the cellular prion protein

Intestinal barrier dysregulation has been proposed to contribute to inflammatory bowel diseases.  Moreover, the low-grade inflammation observed in obese or diabetic patients could be linked to alteration of gut permeability. Cell-cell junctions are major actors of epithelial barriers. Among them, tight junctions, which control paracellular permeability, have been logically the most studied in inflammatory processes. We recently showed that the cellular prion protein is a partner of desmosomal complexes and demonstrated that this protein plays an unexpected role for the proper organization not only of desmosomes but also of adherens and tight junctions and is required for intestinal barrier function.

Role of HIFs (Hypoxia Inducible Factors) in iron metabolism and innate immunity

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.
