关键词: Chronic kidney disease Intestinal barrier Akkermansia muciniphila Intestinal microecology Renal interstitial fibrosis

摘要:
Chronic kidney disease (CKD) affects approximately 10% of the global population. The abundance of Akkermansia muciniphila (AKK) is significantly reduced in CKD patients.This study investigated the effects of AKK bacteria on kidney damage and the renal interstitium in rats with CKD.CKD model 5/6 nephrectomy rats were used. CKD rats were supplemented with AKK (2 × 108 cfu/0.2 mL) for 8 weeks.AKK administration significantly suppressed epithelial-mesenchymal transition (EMT), and high-throughput 16S rRNA pyrosequencing showed that AKK supplementation restored the disordered intestinal microecology in CKD rats. AKK also enhanced the intestinal mucosal barrier function. AKK may regulate the intestinal microecology and reduce renal interstitial fibrosis by enhancing the abundance of probiotics and reducing damage to the intestinal mucosal barrier.The results suggest that AKK administration could be a novel therapeutic strategy for treating renal fibrosis and CKD.Copyright © 2022.
