We recently reported sex differences in the responses of gut microbiota to environmental stimuli, such as salt, with male gut microbiota being more vulnerable to induce high blood pressure than female microbiota. In this study, we investigated the mechanisms by which gut microbiota regulate blood pressure in a sex-dependent manner.</p>
