miR-802 regulates Paneth cell function and enterocyte differentiation in the mouse small intestine

Abstract

Homeostasis of the intestinal epithelium is crucial for the maintenance of the epithelial barrier. Here, the authors show that mir-802 ablation in the mouse intestine impairs enterocyte differentiation and glucose absorption, enhances Paneth cell function by increasing Tmed9-mediated defensin secretion, and increases epithelial cell turnover.
