Patients suffering from kidney diseases have an increased risk of cardiovascular diseases, such as atherosclerosis. Since the AHR can be activated in the kidney by, e.g., tryptophan metabolites and contribute to inflammatory processes, we hypothesized that a deficiency of the\n                    <jats:italic>Ahr<\/jats:italic>\n                    in the kidney epithelium in mice fed a high-fat diet could impact the development of atherosclerosis by altering renal function.
