Lactobacillus reuteri improves function of the intestinal barrier in rats with acute liver failure through Nrf-2/HO-1 pathway

Overall, our study indicated that L. reuteri-induced expression of intestinal tight junction proteins is mediated by the PI3 K/Akt-Nrf-2/HO-1-NF-κB and PKC-Nrf-2/HO-1-NF-κB pathways, which leads to inhibition of the apoptosis of intestinal epithelial cells, thus maintaining the integrity of the damaged intestinal barrier.
