The ameliorative effect of Lactiplantibacillus plantarum SCS2 on DSS-induced murine colitis
The inhibitory effects of Lactiplantibacillus plantarum on inflammatory responses are known, but its action mechanisms in oxidative stress, immunomodulation, and intestinal homeostasis remain of interest. Accordingly, we investigated the protective effects of Lactiplantibacillus plantarum SCS2 (L. plantarum SCS2) against sodium dextran sulfate (DSS)-induced colitis in mice as well as elucidated its impact on inflammation, oxidative stress, and intestinal microbiota. The gut microbiota composition was analyzed by high-throughput 16S rDNA sequencing, and the levels of inflammatory cytokines and oxidative stress indicators in the colon were determined by quantitative polymerase chain reaction and biochemical analysis. The results revealed that pretreatment with L. plantarum SCS2 (10 × 108 CFU/mL) attenuated DSS-induced pathological conditions such as colon shortening and weight loss in mice (P < 0.05). Moreover, the expression of colonic inflammatory factors was reduced, and colonic oxidative stress was regulated. In addition, L. plantarum SCS2 increased the beneficial mouse intestinal flora, which promoted short-chain fatty acid production. Thus, L. plantarum SCS2 could alleviate colitis, showing potential as a novel dietary intervention agent.
期刊介绍:
Research papers must make a significant and original contribution to
microbiology and be of interest to a broad readership. The results of any
experimental approach that meets these objectives are welcome, particularly
biochemical, molecular genetic, physiological, and/or physical investigations into
microbial cells and their interactions with their environments, including their eukaryotic hosts.
Mini-reviews in areas of special topical interest and papers on medical microbiology, ecology and systematics, including description of novel taxa, are also published.
Theoretical papers and those that report on the analysis or ''mining'' of data are
acceptable in principle if new information, interpretations, or hypotheses
emerge.
