文题释义:
P75神经营养因子受体(P75 neurotrophin receptor,P75NTR):是一种基因位于17q12-17q22,分子质量为75 ku且包含427个氨基酸的跨膜受体,是肿瘤坏死因子(TNF)受体超家族的一员,且可以参与多种细胞反应,包括细胞凋亡、存活、突起生长、迁移和细胞周期阻滞等。
脑源性神经营养因子(brain-derived neurotrophic factor,BDNF):是1982年Barde等首先在猪脑中发现的一种具有神经营养作用的蛋白质。脑源性神经营养因子分布在中枢神经系统、周围神经系统、内分泌系统、骨和软骨组织等广泛区域内,但主要是在中枢神经系统内表达,其中海马和皮质的含量最高。
摘要
背景
:P75神经营养因子受体属于低亲和力神经营养因子受体,它不仅在神经生长、发育和维持功能完整性等方面具有重要作用,而且与骨组织修复、增强干细胞特性等方面也密切相关。
目的:对目前P75神经营养因子受体在骨组织修复及再生中的研究进展以及价值进行综述。
方法:计算机检索中国生物医学文献数据库、CNKI数据库、PubMed数据库以及Elsevier数据库的相关文献,检索词为“骨修复,骨再生,P75,P75NTR,bone repair,bone regenerate,tooth development,facial nerve,stem cell”。查阅1987年9月至2018年4月期间收录的P75神经营养因子受体在骨组织再生修复方面的相关文章,最终纳入47篇文献进行结果分析。
结果与结论:①研究报道P75神经营养因子受体能促进牙齿的发育和面神经的修复,促进骨组织的矿化和缩短骨愈合的时间,还能通过调节干细胞的特性来间接促进骨愈合;②也有研究者认为P75神经营养因子受体诱导的细胞凋亡可能会阻碍骨折的愈合,甚至导致骨折不愈合;③对于P75神经营养因子受体在骨组织修复方面所表现出双重作用的通路机制,未来还需要更深入的研究;④目前关于P75神经营养因子受体在骨组织修复的研究还仅仅局限于基础研究,临床应用的报道还很少。

Abstract:

BACKGROUND: P75 neurotrophin receptor holds low affinity, which not only plays an important role in nerve growth, development and maintenance of functional integrity, but also has a close relationship with bone tissue repair and stem cell enhancement.
OBJECTIVE: To review the research progress and value of P75 neurotrophin receptor in bone tissue repair and regeneration.
METHODS: A computer-based search of CBM, CNKI, PubMed and Elsevier was performed for retrieving articles concerning P75 neurotrophin receptor in bone tissue regeneration published from September 1987 to April 2018. The keywords were “P75, P75NTR, bone repair, bone regenerate, tooth development, facial nerve, stem cell” in Chinese and English, respectively. Totally 47 eligible articles were included in final analysis.
RESULTS AND CONCLUSION: P75 neurotrophin receptor has been reported to not only promote tooth development and facial nerve repair, but also promote mineralization of bone tissue and shorten bone healing time. It also indirectly promotes bone healing by regulating the characteristics of stem cells. However, some researchers believe that apoptosis induced by P75 neurotrophin receptor may hinder fracture healing and even lead to fracture failure. Whether P75 neurotrophin receptor can promote bone repair or inhibit bone tissue repair needs further investigation. At present, its research is still limited to basic research, and there are few reports on its clinical application.
