Transforming growth factor beta (TGFβ) is a major signalling pathway in joints. This superfamilly is involved in numerous cellular processes in cartilage. Usually, they are considered to favor chondrocyte differentiation and cartilage repair. However, other studies show also deleterious effects of TGFβ which may induce hypertrophy. This may be explained at least in part by alteration of TGFβ signaling pathways in aging chondrocytes. This review focuses on the functions of TGFβ in joints and the regulation of its signaling mediators (receptors, Smads) during aging and osteoarthritis.
转化生长因子β(TGFβ)是关节中的主要信号通路。这个超家族参与软骨中的众多细胞过程。通常,它们被认为有利于软骨细胞分化和软骨修复。然而,其他研究也表明TGFβ具有有害作用,可能会诱导肥大。这至少部分可以通过衰老软骨细胞中TGFβ信号通路的改变来解释。这篇综述聚焦于TGFβ在关节中的功能以及在衰老和骨关节炎过程中其信号介质(受体、Smads)的调节。
