From gut to blood: How microbiome metabolites orchestrate platelet function

The gut microbiome’s role in human health has gained significant attention, particularly regarding its metabolites’ influence on platelet function and cardiovascular health. This comprehensive review examines the complex relationship between gut microbial metabolites and platelet activity, focusing on key compounds such as trimethylamine N-oxide, 2-methylbutyrylcarnitine, and phenylacetylglutamine. These metabolites affect platelet function through both direct mechanisms, involving specific receptor interactions and calcium signaling pathways, and indirect effects through systemic inflammation. Recent research has revealed that elevated levels of these metabolites correlate with increased cardiovascular risk and altered response to antiplatelet therapy. Understanding these interactions opens new avenues for therapeutic intervention, including targeted metabolic pathway inhibition and personalized medicine approaches. While significant progress has been made, continued research is needed to fully elucidate the complex network of microbiome-platelet interactions and develop effective therapeutic strategies.
