Osteoarthritis (OA) is a widely prevalent chronic degenerative disease often associated with significant pain and disability. It is characterized by the deterioration of cartilage and the extracellular matrix (ECM), synovial inflammation, and subchondral bone remodeling. Recent studies have highlighted pyroptosis-a form of programmed cell death triggered by the inflammasome-as a key factor in sustaining chronic inflammation. Central to this process are the inflammatory cytokines interleukin-1β (IL-1β) and interleukin-18 (IL-18), which play crucial roles mediating intra-articular pyroptosis through the NOD-like receptor protein 3 (NLRP3) inflammasome. This paper investigates the role of the pyroptosis pathway in perpetuating chronic inflammatory diseases and its linkage with OA. Furthermore, it explores the mechanisms of pyroptosis, mediated by nuclear factor κB (NF-κB), the purinergic receptor P2X ligand-gated ion channel 7 (P2X7R), adenosine monophosphate (AMP)-activated protein kinase (AMPK), and hypoxia-inducible factor-1α (HIF-1α). Additionally, it examines the interactions among various cellular components in the context of OA. These insights indicate that targeting the regulation of pyroptosis presents a promising therapeutic approach for the prevention and treatment of OA, offering valuable theoretical perspectives for its effective management.
骨关节炎(OA)是一种广泛流行的慢性退行性疾病,常伴有严重疼痛和功能障碍。其特征在于软骨和细胞外基质(ECM)的退化、滑膜炎症以及软骨下骨重塑。最近的研究强调了焦亡——一种由炎性小体触发的程序性细胞死亡形式——是维持慢性炎症的关键因素。这一过程的核心是炎性细胞因子白细胞介素 -1β(IL -1β)和白细胞介素 -18(IL -18),它们通过NOD样受体蛋白3(NLRP3)炎性小体在介导关节内焦亡中发挥关键作用。本文研究了焦亡途径在慢性炎症性疾病持续存在中的作用及其与骨关节炎的联系。此外,还探讨了由核因子κB(NF -κB)、嘌呤能受体P2X配体门控离子通道7(P2X7R)、单磷酸腺苷(AMP)激活的蛋白激酶(AMPK)和缺氧诱导因子 -1α(HIF -1α)介导的焦亡机制。此外,还研究了在骨关节炎背景下各种细胞成分之间的相互作用。这些见解表明,针对焦亡的调控提出了一种有前景的骨关节炎预防和治疗方法,为其有效管理提供了有价值的理论观点。
