摘要: |
嗜黏蛋白阿克曼菌(A.muciniphila)是一种人类肠道的正常菌群,肥胖患者肠道菌群中的A.muciniphila丰度明显降低。许多证据表明A.muciniphila与肥胖、糖尿病、心血管疾病和低度炎症呈负相关。A.muciniphila不仅可以保护肠道上皮细胞及黏液层的完整性发挥代谢保护作用,在炎症反应过程中A.muciniphila也能通过调节性T细胞、内源性大麻素系统以及非经典Toll样受体发挥抗炎作用。本文就A.muciniphila与肥胖的相关性及分子机制、临床应用等作一综述。 |

Abstract: |
Akkermansia muciniphila (A. muciniphila) is a normal flora of human gastrointestinal tract. The A. muciniphila abundance of intestinal flora in obese patients is significantly decreased. Many evidences suggest that A. muciniphila is negatively related to obesity, diabetes, cardiovascular diseases and low-grade inflammation. A. muciniphila not only plays a metabolic protective role by protecting the integrity of intestinal epithelial cells and mucus layer, but also plays an anti-inflammatory role by regulatory T cells, endogenous cannabinoid system and non-classical Toll-like receptor in the process of inflammatory reaction. This article reviews the relationship between A. muciniphila and obesity, and the molecular mechanism and application of A. muciniphila in obesity. |
