PMID: 34925349 Abstract Title: Effect of Extracellular Vesicles Derived FromQ7 on Gut Microbiota and Ulcerative Colitis in Mice. Abstract: Probiotics plays an important role in regulating gut microbiota and maintaining intestinal homeostasis. Extracellular vesicles (EVs) derived from probiotics have emerged as potential mediators of host immune response and anti-inflammatory effect. However, the anti-inflammatory effect and mechanism of probiotics derived EVs on inflammatory bowel disease (IBD) remains unclear. In this study, the effect ofQ7-derived extracellular vesicles (Q7-EVs) on gut microbiota and intestinal inflammation was investigated in C57BL/6J mice. The results showed that Q7-EVs alleviated DSS-induced colitis symptoms, including colon shortening, bleeding, and body weight loss. Consumption of Q7-EVs reduced the degree of histological damage. DSS-upregulated proinflammatory cytokine levels including IL-6, IL-1β, IL-2 and TNF-α were reduced significantly by Q7-EVs ( [URL='https://www.greenmedinfo.com/article/effect-extracellular-vesicles-derived-lactobacillus-plantarum-q7-gut-microbiot']read more[/URL] [/QUOTE]
