    摘要:

    【目的】验证并筛选具备维生素 A(VA)代谢能力的青春双歧杆菌,并探究其对结肠炎小鼠症状及肠道菌群的影响。【方法】通过体外发酵验证一批青春双歧杆菌的 VA 代谢能力,并选择其中 VA 代谢能力最强的菌株,将其通过灌胃方式对葡聚糖硫酸钠(DSS)诱导的结肠炎小鼠进行干预,干预期为 6 d。试验结束后,评估结肠组织的病理学改变,检测小鼠血清中肠道损伤相关标志物和结肠组织中的细胞因子、抗氧化酶、视黄酸(RA)水平,并采用宏基因组测序技术分析肠道菌群结构变化。【结果】具有最强 VA 代谢能力的青春双歧杆菌 FHNFQ5M4 可显著缓解 DSS 诱导的结肠炎小鼠的肠道损伤,调节结肠组织中细胞因子、RA 的水平,并改善小鼠结肠部位的氧化应激。同时,青春双歧杆菌 FHNFQ5M4 显著改变了结肠炎小鼠的肠道菌群结构,使肠道菌群中富集丁酸单胞菌,而葡萄球菌属的相对丰度降低。【结论】青春双歧杆菌 FHNFQ5M4 能够有效调节小鼠肠道菌群,缓解 DSS 诱导的结肠炎症状,显示出其作为益生菌治疗溃疡性结肠炎(UC)的潜力。

    Abstract:

    [Objective] This study aims to verify and screen the Bifidobacterium adolescentis strains with vitamin A (VA) metabolic capacity, and investigate their effects on colitis symptoms and gut microbiota in mice. [Method] The VA metabolic capacity of a panel of Bifidobacterium adolescentis strains was evaluated through in vitro fermentation, and the strain with the highest VA metabolic capacity was ultimately selected. This strain was administered orally to mice with dextran sulfate sodium (DSS)-induced colitis for 6 consecutive days. After the intervention, histopathological changes in the colonic tissue were assessed, and the levels of intestinal injury markers in the serum and cytokines, antioxidant enzymes, and retinoic acid (RA) in the colonic tissue were measured. Additionally, gut microbiota composition was analyzed by metagenomic sequencing. [Result] Bifidobacterium adolescentis FHNFQ5M4 which possessed the highest VA metabolic capacity significantly alleviated the damage induced by DSS, modulated the cytokine and RA levels, and mitigated the oxidative stress in mouse colonic tissue. Moreover, Bifidobacterium adolescentis FHNFQ5M4 markedly altered the gut microbiota composition in colitis mice, leading to enrichment of Butyricimonas and reduced relative abundance of Staphylococcus. [Conclusion] Bifidobacterium adolescentis FHNFQ5M4 can effectively modulate the gut microbiota and alleviate DSS-induced colitis symptoms in mice, demonstrating the potential as a probiotic candidate for the treatment of ulcerative colitis (UC).
