Osteoarthritis (OA) causes pain and disability in the elderly and has placed a severe burden on healthcare worldwide. Excessive death and decreased density of chondrocytes are recognized as the major pathological characteristic of OA. Chondrocytes have been shown to have multiple forms of death, including apoptosis, pyroptosis, necroptosis, and ferroptosis. The excessive death of chondrocytes often forms a vicious circle with imbalanced chondrocytes extracellular matrix (ECM) metabolism. Therefore, inhibiting chondrocytes excessive death has become a key point that cannot be ignored in the development of OA treatment strategies. We summarized recent studies on the functions and mechanisms of different modes of chondrocyte death and potential therapeutic strategies for OA and offered our views. This may provide direction and theoretical support for formulating OA treatment strategies in the future.
骨关节炎(OA)可导致老年人疼痛和残疾,并给全球医疗保健带来严重负担。过度死亡和软骨细胞密度降低被认为是 OA 的主要病理特征。已经证实软骨细胞有多种形式的死亡,包括凋亡、细胞焦亡、坏死性凋亡和铁死亡。软骨细胞的过度死亡通常与失衡的软骨细胞细胞外基质(ECM)代谢形成恶性循环。因此,抑制软骨细胞过度死亡已成为 OA 治疗策略发展中不可忽视的关键点。我们总结了近期关于不同模式的软骨细胞死亡的功能和机制以及 OA 的潜在治疗策略的研究,并提出了我们的观点。这可能为未来制定 OA 治疗策略提供方向和理论支持。
