%R doi:10.1126/sciadv.abc7409 %X Inflammation is a hallmark of aging and is negatively affecting female fertility. In this study, we evaluate the role of the NLRP3 inflammasome in ovarian aging and female fertility. Age-dependent increased expression of NLRP3 in the ovary was observed in WT mice during reproductive aging. High expression of NLRP3, caspase-1, and IL-1β was also observed in granulosa cells from patients with ovarian insufficiency. Ablation of NLRP3 improved the survival and pregnancy rates and increased anti-Müllerian hormone levels and autophagy rates in ovaries. Deficiency of NLRP3 also reduced serum FSH and estradiol levels. Consistent with these results, pharmacological inhibition of NLRP3 using a direct NLRP3 inhibitor, MCC950, improved fertility in female mice to levels comparable to those of Nlrp3−/− mice. These results suggest that the NLRP3 inflammasome is implicated in the age-dependent loss of female fertility and position this inflammasome as a potential new therapeutic target for the treatment of infertility. %P eabc7409 %L uneatlantico107 %D 2021 %T Inhibition of the NLRP3 inflammasome prevents ovarian aging %V 7 %A José Manuel Navarro-Pando %A Elísabet Alcocer-Gómez %A Beatriz Castejón-Vega %A Elena Navarro-Villarán %A Mónica Condés-Hervás %A María Mundi-Roldan %A Jordi Muntané %A Antonio J.
