微生物区系和远端肠道之间的相互作用是人类健康的基本决定因素。这种相互作用集中在结肠粘膜,并通过产生短链脂肪酸丁酸盐为宿主上皮细胞提供能量。我们试图确定丁酸上皮代谢在建立远端肠道严酷的氧合状态中的作用。细菌来源的丁酸盐影响上皮细胞的氧气消耗,并导致缺氧诱导因子(HIF)的稳定,HIF是一种协调屏障保护的转录因子。抗生素介导的微生物区系的枯竭减少了结肠丁酸盐和HIF的表达,这两者都可以通过补充丁酸盐来恢复。此外,无菌小鼠对O2敏感染料的保留减少,稳定的HIF减少。此外,丁酸的作用在缺乏HIF的细胞中消失,从而将丁酸代谢与稳定的HIF和屏障功能联系起来。这项工作强调了一种机制,即宿主与微生物的相互作用增强了远端肠道的屏障功能。
Interactions between the microbiota and distal gut are fundamental determinants of human health. Such interactions are concentrated at the colonic mucosa and provide energy for the host epithelium through the production of the short-chain fatty acid butyrate. We sought to determine the role of epithelial butyrate metabolism in establishing the austere oxygenation profile of the distal gut. Bacteria-derived butyrate affects epithelial O2 consumption and results in stabilization of hypoxia-inducible factor (HIF), a transcription factor coordinating barrier protection. Antibiotic-mediated depletion of the microbiota reduces colonic butyrate and HIF expression, both of which are restored by butyrate supplementation. Additionally, germ-free mice exhibit diminished retention of O2-sensitive dyes and decreased stabilized HIF. Furthermore, the effects of butyrate are lost in cells lacking HIF, thus linking butyrate metabolism to stabilized HIF and barrier function. This work highlights a mechanism where host-microbe interactions augment barrier function in the distal gut.
