BACKGROUND: This investigation investigates the anti-inflammatory and fibrinolytic effects of a cocktail of probiotics derived from traditional dairy products in a murine model of ulcerative colitis (UC).
MATERIALS AND METHODS: A mix of newly isolated probiotics containing L. plantarum, L. brevis, L. delbrueckii, and L. helveticus was characterized and orally administered to inbred eight-week-old C57BL/6 male mice (n = 6). Clinical symptoms, pathohistological changes, and inflammatory and fibrosis markers were analyzed in the existence and absence of probiotics in colitis mice.
RESULTS: Dairy lactobacillus probiotics potently attenuated colitis symptoms by decreasing dextran sulfate sodium (DSS)-induced body weight loss, colon shortening, rectal bleeding, and rectal prolapse. Consistently, a cocktail of probiotics could significantly improve histopathological grading by suppressing crypt loss, mucosal damage, and inflammation scores in colitis tissues. Moreover, the mix of probiotics suppressed pro-inflammatory genes including interleukin (IL)-1β, IL-6, tumor necrosis factor-alpha (TNF-α), and interferon-gamma (IFN-γ), and increased anti-oxidant markers and activity such as superoxide dismutase and catalase in colon tissue. Furthermore, compared to the no-treated group, the administration of probiotics reduced fibrosis by decreasing collagen deposition in tissue sections and down-regulating levels of pro-fibrotic genes including alpha-actin-2 (Acta2), collagen (Col) 1a1, and Col 1a2 in colitis tissue homogenates.
CONCLUSIONS: The results show the newly isolated cocktail of probiotics elicits a potent protective effect on UC symptoms in mice model. Further study on these probiotics is required to fully explore their effectiveness, strength, and safety considerations.
