Therefore, we aimed to clarify the anti-inflammatory mechanisms of MR inhibition using eplerenone, a selective MR antagonist, in C57BL\/6 mice fed a high-fat diet (HFD) for 12 weeks. Eplerenone prevented excessive body weight gain and fat accumulation, ameliorated glucose intolerance and insulin resistance and enhanced energy metabolism. In the epididymal white adipose tissue (eWAT), eplerenone prevented obesity-induced accumulation of F4\/80\n                    <jats:sup>+<\/jats:sup>\n                    CD11c\n                    <jats:sup>+<\/jats:sup>\n                    CD206\n                    <jats:sup>\u2212<\/jats:sup>\n                    -M1-adipose tissue macrophage (ATM) and reduction of F4\/80\n                    <jats:sup>+<\/jats:sup>\n                    CD11c\n                    <jats:sup>\u2212<\/jats:sup>\n                    CD206\n                    <jats:sup>+<\/jats:sup>\n                    -M2-ATM. Interestingly, M1-macrophage exhibited lower expression levels of MR, compared with M2-macrophage, in the ATM of eWAT and\n                    <jats:italic>in vitro<\/jats:italic>\n                    -polarized bone marrow-derived macrophages (BMDM). Importantly, eplerenone and MR knockdown attenuated the increase in the expression levels of\n                    <jats:italic>proIl1b, Il6<\/jats:italic>\n                    and\n                    <jats:italic>Tnfa,<\/jats:italic>\n                    in the eWAT and liver of HFD-fed mice and LPS-stimulated BMDM. Moreover, eplerenone suppressed IL1b secretion from eWAT of HFD-fed mice. To reveal the anti-inflammatory mechanism, we investigated the involvement of NLRP3-inflammasome activation, a key process of IL1b overproduction. Eplerenone suppressed the expression of the inflammasome components,\n                    <jats:italic>Nlrp3<\/jats:italic>\n                    and\n                    <jats:italic>Caspase1,<\/jats:italic>\n                    in the eWAT and liver. Concerning the second triggering factors, ROS production and ATP- and nigericin-induced IL1b secretion were suppressed by eplerenone in the LPS-primed BMDM. These results indicate that eplerenone inhibited both the priming and triggering signals that promote NLRP3-inflammasome activation. Therefore, we consider MR to be a crucial target to prevent metabolic disorders by suppressing inflammasome-mediated chronic inflammation in the adipose tissue and liver under obese conditions.\n
