Granulosa cells (GCs), the largest cell population and primary source of steroid hormones in the ovary, are the important somatic ovarian components. They have critical roles in folliculogenesis by supporting oocyte, facilitating its growth, and providing a microenvironment suitable for follicular development and oocyte maturation, thus having essential functions in maintaining female fertility and in reproductive health in general. Pyroptotic death of GCs and associated inflammation have been implicated in the pathogenesis of several reproductive disorders in females including Premature Ovarian Insufficiency (POI) and Polycystic Ovary Syndrome (PCOS). Here, I reviewed factors, either intrinsic or extrinsic, that induce or inhibit pyroptosis in GCs in various models of these disorders, both in vitro and in vivo, and also covered associated molecular mechanisms. Most of these studied factors influence NLRP3 inflammasome- and GSDMD (Gasdermin D)-mediated pyroptosis in GCs, compared to other inflammasomes and gasdermins (GSDMs). I conclude that a more complete mechanistic understanding of these factors in terms of GC pyroptosis is required to be able to develop novel strategies targeting inflammatory cell death in the ovary.
颗粒细胞(GCs)是卵巢中最大的细胞群体和类固醇激素的主要来源,是重要的卵巢体细胞成分。它们通过支持卵母细胞、促进其生长以及提供适合卵泡发育和卵母细胞成熟的微环境,在卵泡发生中起着关键作用,因此对维持女性生育能力和生殖健康具有重要作用。GCs 的细胞焦亡和相关炎症与女性多种生殖障碍的发病机制有关,包括卵巢早衰(POI)和多囊卵巢综合征(PCOS)。在这里,我综述了在这些疾病的各种体外和体内模型中,内在或外在因素诱导或抑制 GCs 细胞焦亡的情况,也涵盖了相关的分子机制。与其他炎性小体和 Gasdermins(GSDMs)相比,这些研究的大多数因素影响 NLRP3 炎性小体和 GSDMD(Gasdermin D)介导的 GCs 细胞焦亡。我得出结论,需要更全面地了解这些因素在 GC 细胞焦亡方面的机制,以便能够针对卵巢中炎症性细胞死亡开发新的策略。
