Trimethylamine N-Oxide Generated by the Gut Microbiota Is Associated with Vascular Inflammation: New Insights into Atherosclerosis

Abstract EN

Trimethylamine N-oxide (TMAO) is a biologically active molecule generated by the gut microbiota.

Accumulating evidences have indicated a close association between high plasma TMAO levels and the risk of developing atherosclerosis (AS).

AS is considered a chronic inflammatory disease initiated by vascular endothelial inflammatory injury.

Both observational and experimental studies suggest that TMAO can cause endothelial inflammatory injury.

However, a clear mechanistic link between TMAO and vascular inflammation of AS is not yet summarized.

In this review, we discuss the association between TMAO and AS and focus on the potential role of TMAO in endothelial inflammatory injury.

Finally, the utility of TMAO-targeted therapeutic strategies for the treatment of AS is also analyzed.
