Gut microbiota-derived metabolite phenylacetylglutamine in cardiovascular and metabolic diseases

The aging of population coupled with unhealthy dietary habits among residents has led to a rise in the incidence of cardiovascular and metabolic diseases (CVMDs). Extensive research has highlighted the role of gut microbiota-derived metabolites in CVMDs. Among these metabolites, phenylacetylglutamine (PAGln), a meta-organismal prothrombotic metabolite, has been proved to promote the progression of CVMDs. This bacterial derived metabolite is a byproduct of amino acid comes from phenylalanine (Phe) in the diet. There are increasing evidence showing that the level of PAGln is associated with the risk of developing CVMDs. To provide a comprehensive understanding of the role of PAGln in CVMDs, this review delves into the production and metabolic pathways of PAGln and discusses the links of PAGln and the pathogenesis of CVMDs.
