Abstract:

The nonalcoholic fatty liver disease (NAFLD) is a progressive liver disease that affects the health of people in an increasing rate. In the current research, we investigated the beneficial effect of a novel probiotic strainJlus66 (Jlus66) on rats with high-fat diet (HFD)-induced NAFLD. The intestinal flora of rats was analyzed based on V3-V4 region 16S rDNA sequencing. Moreover, we measured the oxidative stress and inflammation factors in the liver using commercial ELISA kit, and the lipopolysaccharide (LPS) in serum with chromogenic end-point tachypheus amebocyte lysate. Compared with the HFD-induced group, Jlus66 treatment significantly decreased the malondialdehyde (MDA) level in the serum ( < 0.05). Additionally, Jlus66 significantly enhanced the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in the liver and serum ( < 0.05). Jlus66 administration also reduced the levels of tumor necrosis factor (TNF-α) and interleukin-6 (IL-6), and inversely increased the interleukin-10 (IL-10) level in serum ( < 0.05). Intestinal flora analysis results showed that Jlus66 can improve intestinal flora structure by increasing the abundance of gram-positive flora such as Firmicutes, and decreasing gram-negative flora such as Bacteroidetes, Proteobacteria, and Fusobacteria, and then reduced LPS concentration in the serum. So we concluded that Jlus66 can improve NAFLD by modulating the intestinal flora and followed reduction of oxidative stress (OxS) and inflammation.
