Beneficial Effects of Probiotics on Liver Injury Caused by Chronic Alcohol Consumption

Abstract

Alcoholic liver injury is a serious risk to human health. Probiotics have become a popular form of treatment. Lacticaseibacillus casei Grx12 and Limosilactobacillus fermentum Grx07 isolated from the gut of long-lived people in Rugao, Jiangsu, were studied to determine their protective effects and possible mechanisms of action on alcoholic liver injury. The results showed that rat serum ALT and AST were restored, and liver injury was reduced after the probiotics intervention. The level of antioxidant enzymes and antioxidants such as SOD, GSH and GSH-Px in the rat liver was significantly increased (p L. casei Grx12 and L. fermentum Grx07 also could significantly enhance the expression of Nrf2 protein in the rat liver to regulate the anti-oxidative stress response in the body and cells (p +-K+-ATPase and Ca2+-ATPase in the rat liver were significantly increased (p p L. casei Grx12 and L. fermentum Grx07 have certain protective effects on alcoholic liver injury in rats, likely because of their antioxidant properties and ability to prevent oxidative stress and relieve inflammation.
