G-protein-coupled receptors (GPCRs) are linked to a plethora of human diseases, but the efficacy of drugs that target GPCRs often varies between patients. Now, a link has been established between the gut microbiome and GPCR drug metabolism, in which the identities of the microbes directly influence the metabolites formed and the host drug response.
