摘 要：Purpose: The signals responsible for homeostasis in the periodontal complex are unclear. The purpose of this study was to evaluate the role of Low-density lipoprotein receptor-related protein 5(LRP5) in this process by removing LRP5, and observing the effects of LRP5 depletion on cells of the periodontal structures. Material and Methods: The function of this LRP5 was evaluated by conditional elimination of the LRP5 gene using an Osteocalcin Cre driver. The OCN-Cre;? mice were examined using micro-CT and histology, immunohistochemistry to evaluate the periodontal complex. Results: Elimination of LRP5 in the periodontal complex of OCN-Cre;??mice results in a different expression of Fibromodulin in the periodontal ligament space. A decrease in osteoclastic activity was found in the periodontal ligament. Conclusion: Osteoclastic activities are decreased and expression of fibromodulin is decreased, which implies the involvement of LRP5 in homeostasis of the periodontal ligament.
