主 题：primary cilia bone mechanical sensing hard tissue cilium-related bone disease tooth
摘 要：Bone and teeth are hard tissues.Hard tissue diseases have a serious effect on human survival and quality of life.Primary cilia are protrusions on the surfaces of cells.As antennas,they are distributed on the membrane surfaces of almost all mammalian cell types and participate in the development of organs and the maintenance of homeostasis.Mutations in cilium-related genes result in a variety of developmental and even lethal diseases.Patients with multiple ciliary gene mutations present overt changes in the skeletal system,suggesting that primary cilia are involved in hard tissue development and reconstruction.Furthermore,primary cilia act as sensors of external stimuli and regulate bone homeostasis.Specifically,substances are trafficked through primary cilia by intraflagellar transport,which affects key signaling pathways during hard tissue development.In this review,we summarize the roles of primary cilia in long bone development and remodeling from two perspectives:primary cilia signaling and sensory mechanisms.In addition,the cilium-related diseases of hard tissue and the manifestations of mutant cilia in the skeleton and teeth are described.We believe that all the findings will help with the intervention and treatment of related hard tissue genetic diseases.
