Gut-Derived Metabolite Trimethylamine N-Oxide Promotes Inflammation and Fibrosis Following Ischemia/Reperfusion through CCR2-Mediated Macrophage Infiltration

GSE244890 Mus musculus Expression profiling by high throughput sequencing 4 samples Submitted 2024/09/09 Platform GPL19057
Summary
Inflammation plays a crucial role in the development of acute kidney injury (AKI) and subsequent chronic kidney disease (CKD) following renal ischemia-reperfusion (IR). It has been demonstrated that metabolites from the gut microbiota can trigger inflammatory responses and modulate renal damage induced by IR. However, the exact driving factors and underlying mechanisms of this process remain unclear. Trimethylamine N-oxide (TMAO), a choline metabolite derived from the gut, has been observed to increase in AKI and CKD patients. Our study reveals that glycyrrhizic acid (GA) exacerbates IR-induced AKI and subsequent CKD through TMAO. To delve into the underlying mechanisms, we employed single-cell sequencing to construct a molecular map of kidney cells.
