Physiological bone remodeling is a highly coordinated process responsible for bone resorption and formation and is necessary to repair damaged bone and to maintain mineral homeostasis. In addition to the traditional bone cells (osteoclasts, osteoblasts, and osteocytes) that are necessary for bone remodeling, several immune cells have also been implicated in bone disease. This minireview discusses physiological bone remodeling, outlining the traditional bone biology dogma in light of emerging osteoimmunology data. Specifically discussed in detail are the cellular and molecular mechanisms of bone remodeling, including events that orchestrate the five sequential phases of bone remodeling: activation, resorption, reversal, formation, and termination.
生理骨重塑是一个高度协调的过程,负责骨吸收和形成,对于修复受损的骨骼和维持矿物质的体内平衡是必需的。除了传统的骨细胞(破骨细胞、成骨细胞和成骨细胞)对骨重塑是必需的之外,几种免疫细胞也与骨疾病有关。这篇小综述讨论了生理骨重塑,根据新兴的骨免疫学数据,概述了传统的骨生物学教条。本文详细讨论了骨重塑的细胞和分子机制,包括协调骨重塑的五个连续阶段(激活、吸收、逆转、形成和终止)的事件。
