文题释义:
钙调磷酸酶:最早是由克利、克劳奇和克林克斯在1979年基于它与钙结合性能及对神经组织定位功能首先提出的。钙调磷酸酶是一种广泛分布于人体各种组织的 Ca2+离子依赖性丝/苏氨酸(Ser/Thr)蛋白磷酸酶,又称为蛋白磷酸酶 2B(protein phosphatase 2B, PP2B)。钙调磷酸酶由催化亚基A(Cna1)和一个调节亚基B(Cnb1)及3个催化亚基(CnaA, CnaB and CnaC)组成[9]。作为Ca2+信号调节途径的关键酶,它参与了多项重要生理功能或一些病理过程的调节如T细胞活化、肌肉量调节、学习记忆的形成和老年痴呆症的发生等。
活化T细胞核因子(NFAT):其转录因子家族包括活化T细胞核因子c1-4和活化T细胞核因子5五个成员,活化T细胞核因子是由特殊的磷酸酶和钙调磷酸酶激活。细胞在静息状态下,活化T细胞核因子家族成员除了活化T细胞核因子5,N-末端调节结构区高度磷酸化均保留在细胞质中。该信号通路在持续钙离子内流作用下最终激活钙调磷酸酶,活化T细胞核因子蛋白质高度脱磷酸化促进其转位到细胞核并激活。
 
摘要
背景:假体周围骨溶解以及伴随的无菌性松动是全关节置换翻修手术的最常见原因。研究发现钙调磷酸酶/活化T细胞核因子信号通路在磨损颗粒诱导假体周围骨溶解中发挥重要作用。
目的:归纳总结钙调磷酸酶/活化T细胞核因子在磨损颗粒诱导骨溶解中的作用,为骨溶解相关疾病提供新思路和新理论。
方法:计算机检索PubMed数据1980年1月至2016年6月相关文献;检索词为“CN/NFAT;CN/NFATsignaling pathways;Wear particles;osteolysis;osteoclasts;osteoblast”。根据纳入排除标准对最终选定的72条文献进行分析探讨。
结果与结论:骨溶解的发病机制涉及巨噬细胞和被磨损颗粒激活的各种促炎细胞因子的释放。骨骼发育是通过骨吸收和骨重建之间的动态平衡相互偶联,机体维持正常骨量和骨密度的基础是成骨细胞的骨重建和破骨细胞的骨吸收。在这个过程中, 钙调磷酸酶/活化T细胞核因子信号传导通路正是与Ca2+信号和核因子κB受体活化因子配体参与破骨细胞分化相关的信号传导通路。破骨细胞和胞核因子κB受体活化因子配体分别在骨吸收的生理病理过程中及破骨细胞生成过程中发挥关键作用。

Abstract:

BACKGROUND: Periprosthetic osteolysis and subsequent aseptic loosening are most common reasons for revision after total joint replacements. Recently studies found that calcineurin/activated T cell nuclear factor (CN/NFAT) signaling pathway plays important roles in the pathogenic process of wear-induced inflammation and osteolysis.

OBJECTIVE: To summarize CN/NFAT effects on wear particles-induced osteolysis, and to provide new ideas and new theories for osteolysis-related diseases.
METHODS: We retrieved PubMed for studies published from January 1980 to June 2016. The key words were “CN/NFAT, CN/NFAT signaling pathways, wear particles, osteolysis, osteoclasts, osteoblast”. Finally, 72 studies were analyzed and explored according to inclusion and exclusion criteria.
RESULTS AND CONCLUSION: The pathogenesis of osteolysis involves the activation of macrophages by wear particles and the release of various proinflammatory cytokines. Bone is continuously renewed through a dynamic balance between bone resorption and formation and is the fundamental basis for maintaining normal bone mass and architecture by osteoclasts and osteoblasts. In this process, CN/NFAT signaling pathway is the signal transduction pathway involved in the differentiation of Ca2+ and nuclear factor kappa B receptor ligand. Osteoclasts play a significant role in both physiological and pathological bone resorption, and receptor activator of nuclear factor-κB ligand is the key cytokine that induces osteoclastogenesis.
