Alleviation effects of Lactobacillus plantarum in colitis aggravated by a high-salt diet depend on intestinal barrier protection, NF-κB pathway regulation, and oxidative stress improvement

. HGD228 treatment also enhanced the production of butyric acid and acetic acid, suppressed pro-inflammatory cytokines, and strengthened the intestinal mucosal barrier. Therefore, HGD228 enhanced the production of beneficial metabolites by regulating inflammatory cytokines and oxidative stress, preserving the mucosal barrier, and enhancing gut microbiota, and mitigated colitis aggravated by a HSD. These results will aid in clinical trials of probiotics and the development of dietary supplements for colitis, with promising application value.
