Abstract:

Pathogenesis of alcohol-related diseases such as alcoholic hepatitis involves gut barrier dysfunction, endotoxemia, and toxin-mediated cellular injury. Here we show that Lactobacillus plantarum not only blocks but also mitigates ethanol (EtOH)-induced gut and liver damage in mice. L. plantarum blocks EtOH-induced protein thiol oxidation, and down-regulation of antioxidant gene expression in colon L. plantarum also blocks EtOH-induced expression of TNF-α, IL-1β, IL-6, monocyte chemotactic protein 1 ( MCP1), C-X-C motif chemokine ligand ( CXCL)1, and CXCL2 genes in colon. Epidermal growth factor receptor (EGFR) signaling mediates the L. plantarum-mediated protection of tight junctions (TJs) and barrier function from acetaldehyde, the EtOH metabolite, in Caco-2 cell monolayers. In mice, doxycycline-mediated expression of dominant negative EGFR blocks L. plantarum-mediated prevention of EtOH-induced TJ disruption, mucosal barrier dysfunction, oxidative stress, and inflammatory response in colon. L. plantarum blocks EtOH-induced endotoxemia aswell as EtOH-induced pathologic lesions, triglyceride deposition, oxidative stress, and inflammatory responses in the liver by an EGFR-dependent mechanism. L. plantarum treatment after injury accelerated recovery from EtOH-induced TJ, barrier dysfunction, oxidative stress, and inflammatory responsein colon, endotoxemia, and liver damage. Results demonstrate that L. plantarum has both preventive and therapeutic values in treatment of alcohol-induced tissue injury, particularly in alcoholic hepatitis.-Shukla, P. K., Meena, A.
