摘要:


文题释义:
滑膜液外泌体:由滑膜腔内的多种细胞(如滑膜细胞、软骨细胞、免疫细胞等)分泌,富含蛋白质、脂质、核酸等信息分子,具有高度稳定性、组织靶向性和生物活性。
膝骨关节炎:是一种常见的慢性退行性、非特异性炎症的关节疾病,在慢性炎症环境的影响下,膝关节可出现滑膜炎症、软骨退变以及关节功能的逐渐丧失。

背景:越来越多的证据表明滑膜液外泌体介导滑膜细胞-软骨细胞信号互作在膝骨关节炎中的重要作用。滑膜细胞与软骨细胞的信号互作,从分子层面揭示了滑膜液外泌体在膝骨关节炎进展中的双向调控作用。
目的:从多角度、多层次、全方位阐释滑膜液外泌体介导滑膜细胞与软骨细胞的信号交互作用,以期为相关领域的研究与临床应用提供新思路与新视角。
方法:检索PubMed数据库2001年1月至2025年6月的文献,以“Osteoarthritis*,Exosomes,Synovial cells,Chondrocytes”为检索词,检索2001年1月至2025年6月发表的所有相关文献,纳入原始研究、综述及临床试验等文献,排除无关机制及与主题相关性低的文献,最终筛选93篇文献进行综合分析。
结果与结论:在膝骨关节炎发生与发展过程中,滑膜细胞与软骨细胞之间借助滑膜液外泌体建立了密切的信号交流,这种信号互作显著影响膝骨关节炎的进展,既能加剧软骨退变和滑膜炎症,也可能在特定条件下发挥保护性调控作用。因此,该机制的双面性凸显了对它进行精准干预的必要性,而针对外泌体介导的细胞间信号通路的关键分子,有望为膝骨关节炎提供新的治疗策略与靶点。

Abstract: BACKGROUND: Increasing evidence has demonstrated the crucial role of synovial cell-chondrocyte signaling crosstalk mediated by synovial fluid exosomes in knee osteoarthritis. The signaling interaction between synovial cells and chondrocytes reveals, at the molecular level, the bidirectional regulatory role of synovial fluid exosomes in the progression of knee osteoarthritis. 
OBJECTIVE: To comprehensively interpret the interactions between synoviocytes and chondrocytes mediated by synovial fluid exosomes from multiple perspectives and levels to provide new insights and directions for research and clinical applications in the related field. 
METHODS: A literature search was conducted in PubMed for publications from January 2001 to June 2025 using the keywords “osteoarthritis*, exosomes, synovial cells, chondrocytes.” All relevant original studies, reviews, and clinical trials published from January 2001 to June 2025 were included, while irrelevant mechanisms and studies with low relevance to the topic were excluded. A total of 93 articles were ultimately included for comprehensive analysis.
RESULTS AND CONCLUSION: During the onset and progression of knee osteoarthritis, synoviocytes and chondrocytes establish close signal communication through synovial fluid exosomes. This interaction significantly affects knee osteoarthritis progression, not only exacerbating cartilage degeneration and synovial inflammation, but also potentially exerting protective and regulatory effects under certain conditions. Therefore, the dual role of this mechanism highlights the necessity of precise intervention. Targeting the key molecules in exosome-mediated intercellular signaling pathways may provide novel therapeutic strategies and targets for knee osteoarthritis.


Key words: knee osteoarthritis, synovial fluid, exosomes, chondrocytes, synoviocytes, crosstalk, protection and repair, inflammatory response
