在传统上被归类为辅助性T细胞(Th)1型疾病的自身免疫性关节炎中,T细胞的激活导致破骨细胞介导的骨破坏,但尽管干扰素(IFN)具有抗破骨细胞生成作用,但T细胞如何增强破骨细胞生成仍有待阐明。-γ。在这里,我们研究了各种Th细胞亚群对破骨细胞生成的影响,并确定了Th 17,一个专门的炎症亚群,作为破骨细胞生成Th细胞亚群,连接T细胞活化和骨吸收。白细胞介素(IL)-23-IL-17轴,而不是IL-12-IFN-γ轴,不仅对自身免疫性关节炎的发病阶段至关重要,而且对骨破坏阶段也至关重要。因此,Th 17是与T细胞活化相关的骨破坏的有力治疗靶标。
In autoimmune arthritis, traditionally classified as a T helper (Th) type 1 disease, the activation of T cells results in bone destruction mediated by osteoclasts, but how T cells enhance osteoclastogenesis despite the anti-osteoclastogenic effect of interferon (IFN)-γ remains to be elucidated. Here, we examine the effect of various Th cell subsets on osteoclastogenesis and identify Th17, a specialized inflammatory subset, as an osteoclastogenic Th cell subset that links T cell activation and bone resorption. The interleukin (IL)-23–IL-17 axis, rather than the IL-12–IFN-γ axis, is critical not only for the onset phase, but also for the bone destruction phase of autoimmune arthritis. Thus, Th17 is a powerful therapeutic target for the bone destruction associated with T cell activation.
