Zusammenfassung
The intestinal epithelium represents the largest epithelial surface in our body. This single cell-layer epithelium mediates important functions in the absorption of nutrients and in the maintenance of barrier function, preventing luminal microorganism from invading the body. Due to its constant regeneration the intestinal epithelium is not only a tissue with very high proliferation rates, but also with very prominent physiological and pathophysiological cell death induction. The normal physiological differentiation and maturation of intestinal epithelial cells (IECs) leads to their shedding and apoptotic cell death within few days, without disturbing the epithelial barrier integrity. In contrast excessive IEC cell death induced by irradiation, drugs and inflammation severely impairs the vital functions of this tissue. In this review we discuss cell death processes in the intestinal epithelium in health and disease, with special emphasis on TNF receptor family-triggered cell death.The intestinal epithelium represents the largest epithelial surface in our body.
