| 1 | Niobium carbide(MXene)reduces UHMWPE particle-induced osteolysis显示文摘Joint replacement surgery is one of the orthopedic surgeries with high successful rates;however,wear debris generated from prostheses can ultimately lead to periprosthetic osteolysis and failure of the implant.The implant-derived particulate debris such as ultrahigh molecular weight polyethylene(UHMWPE)can initiate the local immune response and recruit monocytic cells to phagocytose particles for generating reactive oxygen species(ROS).ROS induces osteoclastogenesis and macrophages to secrete cytokines which ultimately promote the development of osteolysis.In this work,we develop the few-layered Nb_(2)C(FNC)as an antioxidant which possesses the feature of decreasing the production of cytokines and inhibiting osteoclastogenesis by its ROS adsorption.Moreover,local injection of FNC attenuates the UHMWPE-induced osteolysis in a mouse calvarial model.In sum,our results suggest that FNC can be used for treating osteolytic bone disease caused by excessive osteoclastogenesis. | Kuo-Yang Sun Yizhang Wu Jia Xu Wenfang Xiong Wei Xu Jiawei Li Ziying Sun Zhongyang Lv XSWu Qing Jiang Hong-Ling Cai Dongquan Shi | 2022 | Bioactive Materials2022，7，2： | 0 |
