Osteoporosis represents a systemic imbalance in bone metabolism, augmenting the susceptibility to fractures among patients and emerging as a notable mortality determinant in the elderly population. It has evolved into a worldwide concern impacting the physical well-being of the elderly, imposing a substantial burden on both human society and the economy. Presently, the precise pathogenesis of osteoporosis remains inadequately characterized and necessitates further exploration. The advancement of osteoporosis is typically linked to the initiation of an inflammatory response. Cells in an inflammatory environment can cause inflammatory death including pyroptosis. Pyroptosis is a recently identified form of programmed cell death with inflammatory properties, mediated by the caspase and gasdermin families. It is regarded as the most inflammatory form of cell death in contemporary medical research. Under the influence of diverse cytokines, macrophages, and other immune cells may undergo pyroptosis, releasing inflammatory factors, such as IL-1β and IL-18. Numerous lines of evidence highlight the pivotal role of pyroptosis in the pathogenesis of inflammatory diseases, including cancer, intestinal disorders, hepatic conditions, and cutaneous ailments. Osteoporosis progression is frequently associated with inflammation; hence, pyroptosis may also play a role in the pathogenesis of osteoporosis to a certain extent, making it a potential target for treatment. This paper has provided a comprehensive summary of pertinent research concerning pyroptosis and its impact on osteoporosis. The notion proposing that pyroptosis mediates osteoporosis via the inflammatory immune microenvironment is advanced, and we subsequently investigate potential targets for treating osteoporosis through the modulation of pyroptosis.
骨质疏松症代表着一种骨骼代谢的系统性失衡,增加了患者骨折的易感性,并成为老年人群中显著的死亡决定因素。它已经成为一个全球性的问题,影响着老年人的身体健康,给人类社会和经济带来了巨大的负担。目前,骨质疏松症的确切发病机制仍描述不足,需要进一步探索。骨质疏松症的进展通常与炎症反应的启动有关。炎症环境中的细胞可引起炎症性细胞死亡,包括细胞焦亡。细胞焦亡是一种最近发现的具有炎症特性的程序性细胞死亡形式,由半胱氨酸天冬氨酸蛋白酶(caspase)和 Gasdermin 家族介导。它被认为是当代医学研究中最具炎症性的细胞死亡形式。在各种细胞因子的影响下,巨噬细胞和其他免疫细胞可能会发生细胞焦亡,释放炎症因子,如 IL-1β 和 IL-18。大量证据表明细胞焦亡在炎症性疾病的发病机制中起关键作用,包括癌症、肠道疾病、肝脏疾病和皮肤疾病。骨质疏松症的进展常与炎症有关;因此,细胞焦亡在一定程度上也可能在骨质疏松症的发病机制中发挥作用,使其成为治疗的潜在靶点。本文全面总结了与细胞焦亡及其对骨质疏松症影响相关的研究。提出细胞焦亡通过炎症免疫微环境介导骨质疏松症的观点,随后我们探讨通过调节细胞焦亡来治疗骨质疏松症的潜在靶点。
