Research in Cell reveals that the biological identity of different colon regions is primarily established by the microbiome rather than being an inherent trait of intestinal stem cells. The study identifies nicotinic acid as a critical microbial metabolite concentrated in the proximal colon that triggers the PPARα signaling pathway to define local cellular characteristics. When the microbiome is d...去小宇宙查看完整单集简介
