, a probiotic, is a gram-positive obligate anaerobic bacillus with acid and heat resistant properties. Previous studies have reported that  has beneficial effects in intestinal diseases and regulates intestinal function. The aim of the present study was to investigate the protective effects and mechanisms of  on the intestinal barrier function. Mice were randomly divided into three experimental groups (n=15 mice/group), including control, dextran sodium sulfate (DSS) and DSS + . In the DSS and DSS +  groups colitis was induced with 3% DSS dissolved in drinking water for 7 days. DSS +  group mice were co-treated daily with 200 µl (2x10 CFU)  solution via gavage. The intestinal mucosal barrier function in mice was assessed by measuring FITC-labeled 4-kDa dextran (molecular weight, 4,000 Da) flux and by analyzing the expression of tight junction (TJ)-related proteins using western blot analysis. In addition, the secretion levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, IL-10 and IL-13, and the concentration of malondialdehyde, glutathione and superoxide dismutase were detected using ELISAs to determine inflammation and oxidative stress, respectively. The activation status of the Akt/mTOR signaling pathway was also investigated using western blot analysis. The results demonstrated that, in mice with DSS-induced colitis treatment, co-treatment with  attenuated colitis symptoms and intestinal permeability, increased the expression levels of TJ-related proteins, decreased TNF-α, IL-1β and IL-13 secretion levels but increased those of IL-10, and reduced oxidative stress. Additionally,  elevated the phosphorylation of Akt, mTOR and p70 ribosomal protein S6 kinase. Collectively, the present results indicated that  protected intestinal barrier function and decreased intestinal mucosal permeability via upregulating the expression levels of TJ-related proteins in a mouse model of DSS-induced colitis. Moreover, the results suggested that the effects of  could be mediated by the Akt/mTOR signaling pathway.
