Abstract:
Trauma induces immune cells to infiltrate the fracture site, and regulates the removal of local dead bone and remodeling of new bone by secreting a variety of cytokines and inflammatory mediators. With the development of trauma immunology, the role of the immune system in the process of bone wound healing has been deeply studied in recent years. When fracture occurs, the non-specific and specific immune cells are successively attracted into the fracture site, participating in bone repair. If there was a disorder in the bone trauma microenvironment, the coordination between osteoblasts and osteoclasts will be disordered, leading to delayed or nonunion of fractures. Therefore, it is very important to systematically explore the communication between immune cells and immune cells or osteoblasts/osteoclasts in bone trauma microenvironment. The authors review the immune regulation mechanism in the process of bone clearance and repair after bone trauma, and provide a rationale for the future immunotherapy of bone trauma.
