摘要:

文题释义:
自噬:是细胞在危险环境中的一种自我保护机制,主要通过溶酶体途径将机体内部受损的蛋白质或者不需要的细胞器进行快速降解,其产物可作为营养物质再重新利用以维持内环境稳定,但过度的自噬会导致骨代谢性疾病。
牙槽骨骨代谢:牙槽骨进行新陈代谢时,需成骨细胞和破骨细胞协同作用,以维持骨组织的正常骨稳态,但患有牙周炎、根尖周炎或骨质疏松等慢性炎性疾病时,牙槽骨骨代谢过程发生紊乱,易造成牙槽骨吸收。

背景:自噬具有清除受损蛋白质或过多细胞器的作用,能够帮助细胞适应不良环境改变,维持细胞内环境稳定和自我更新,但自噬异常或者功能障碍将导致骨代谢性疾病的发生。 
目的:综述自噬对炎性牙槽骨代谢的影响。
方法:第一作者检索PubMed、Web of Science、Geenmedical、知网、万方等数据库,以“autophagy,osteoblasts,osteoclasts,NLRP3,bone metabolism”为英文检索词,以“自噬,成骨细胞,破骨细胞,NLRP3,骨代谢”为中文检索词,检索2011年1月至2021年11月已发表的所有相关文献,并对其进行了筛选、归纳与分析,最后纳入63篇文献进行综述。
结果与结论:①自噬对机体具有保护作用,适度激活自噬有利于维持骨组织内环境稳态,而自噬途径紊乱或异常可能会扰乱骨重建过程中的动态平衡,造成牙槽骨代谢性疾病的发生;②NLRP3炎性小体与自噬具有双向调控作用,自噬可能通过调控NLRP3炎性小体在牙槽骨代谢性疾病的发生发展过程中发挥重要作用。 
缩略语:核苷酸结合寡聚化结构域样受体蛋白3:nucleotide-binding oligomerization domain-like receptor protein 3,NLRP3

Abstract: BACKGROUND: Autophagy can remove damaged proteins or excessive organelles, help cells adapt to adverse environmental changes, and maintain intracellular environment stability and self-renewal. However, abnormalities or dysfunctions in autophagy will lead to bone metabolic diseases.
OBJECTIVE: To review the effect of autophagy on inflammation-induced alveolar bone metabolism.
METHODS: The first author searched PubMed, Web of Science, Geenmedical, WanFang, and CNKI databases for relevant articles published from January 2011 to November 2021. The search terms were “autophagy, osteoblasts, osteoclasts, NLRP3, bone metabolism” in English and Chinese, respectively. Finally, 63 articles were included in result analysis after screening, analyzing and summarizing.
RESULTS AND CONCLUSION: Autophagy has a protective effect on the body. Moderate activation of autophagy is conducive to maintaining the internal environment homeostasis in bone tissue, and disorder or abnormality of autophagy pathways may disturb the dynamic balance during bone remodeling, resulting in the occurrence of alveolar bone metabolic diseases. NLRP3 inflammasomes and autophagy have a bidirectional regulatory effect and autophagy may play an important role in the occurrence and development of metabolic diseases in the alveolar bone by regulating NLRP3 inflammasomes.

Key words: autophagy, osteoblast, osteoclast, NLRP3, bone metabolism, review
