摘要(Abstract):

炎症性关节炎是一类以关节炎症、软骨破坏、骨侵蚀及免疫紊乱为核心特征的慢性疾病,涵盖类风湿关节炎(RA)、骨关节炎(OA)、强直性脊柱炎(axSpA)等亚型,其发病与炎症介质、免疫细胞及组织微环境异常密切相关。前列腺素E₂(PGE₂)作为花生四烯酸代谢关键炎症介质,通过多受体亚型介导的信号转导,在炎症反应、免疫调控及骨软骨代谢平衡中发挥核心作用,是疾病病理进程的关键调控分子。本文系统综述PGE₂的生物合成与信号调控基础,探讨其对先天免疫与适应性免疫的调控机制,解析其在炎症性关节炎中的病理作用及骨软骨破坏机制,总结基于PGE₂通路的治疗策略与前景,为疾病精准治疗提供理论依据。
