In the pathogenesis of osteoarthritis, various signaling pathways may influence the bone joint through a common terminal pathway, thereby contributing to the pathological remodeling of the joint. Semaphorins (SEMAs) are cell-surface proteins actively involved in and primarily responsible for regulating chondrocyte function in the pathophysiological process of osteoarthritis (OA). The significance of the SEMA family in OA is increasingly acknowledged as pivotal. This review aims to summarize the mechanisms through which different members of the SEMA family impact various structures within joints. The findings indicate that SEMA3A and SEMA4D are particularly relevant to OA, as they participate in cartilage injury, subchondral bone remodeling, or synovitis. Additionally, other elements such as SEMA4A and SEMA5A may also contribute to the onset and progression of OA by affecting different components of the bone and joint. The mentioned mechanisms demonstrate the indispensable role of SEMA family members in OA, although the detailed mechanisms still require further exploration.
在骨关节炎的发病机制中,各种信号通路可能通过共同的末端通路影响骨关节,从而导致关节的病理性重塑。信号素(SEMA)是细胞表面蛋白,在骨关节炎(OA)的病理生理过程中积极参与并主要负责调节软骨细胞的功能。SEMA 家族在 OA 中的重要性越来越被认可。本综述旨在总结不同 SEMA 家族成员影响关节内各种结构的机制。研究结果表明,SEMA3A 和 SEMA4D 与 OA 特别相关,因为它们参与软骨损伤、软骨下骨重塑或滑膜炎。此外,其他因子,如 SEMA4A 和 SEMA5A,也可能通过影响骨骼和关节的不同成分而导致 OA 的发生和发展。所述机制表明 SEMA 家族成员在 OA 中不可或缺,尽管详细的机制仍需要进一步探索。
