背景情况:
- 麦炭胺具有抗氧化和抗炎性质.
- 这些影响背后的确切机制尚未完全理解.
- 高脂肪饮食诱导肠道炎症和氧化应激.
研究的目的:
- 为了研究麦炭胺B (AVN B) 对高脂肪饮食 (HFD) 诱导的小鼠肠道炎症的影响.
- 阐明AVN B行动的基本机制.
- 评估AVN B对肠道屏障功能,炎症途径和肠道微生物群的影响.
主要方法:
- 给小鼠食高脂肪饮食 (HFD),有或没有AVN B补充剂.
- 测量包括体重,血清和组织炎症/氧化应激标志物.
- 分析了肠道屏障蛋白 (Occludin,MUC2),TLR4/NF-κB通路激活,以及肠道微生物群组成.
主要成果:
- 补充AVN B减轻了HFD诱导的体重增加,并减少了炎症和氧化应激标志物.
- AVN B通过上调奥克卢丁和MUC2来改善肠道屏障功能.
- AVN B抑制了TLR4/NF-κB通路,减少了促炎因素,并增强了有益的肠道细菌和短链脂肪酸 (SCFA) 生产.
