神经系统在调控皮肤创伤修复和瘢痕愈合中的重要作用

The important role of the nervous system in regulating wound repair and scar healing

背景:皮肤创伤修复是一个极其复杂的过程,神经系统在调控创伤修复和瘢痕愈合方面发挥重要作用。目的:对皮肤创伤修复过程中神经系统的作用,包括相关因子、多种细胞对损伤皮肤修复的作用进行综述。方法:检索PubMed及中国知网数据库2003-2024年发表的文献,英文检索词为“skin wound healing,nervous system,nerve regeneration,growth factor”,中文检索词为“皮肤创伤修复,皮肤神经支配,神经肽,生长因子,细胞协同作用”。最终筛选出83篇文献进行分析。结果与结论:①皮肤受到自主神经和感觉神经的密集支配,越来越多的证据表明,皮肤神经系统不仅负责向中枢神经系统传递感觉信息,而且在包括伤口愈合在内的各种皮肤功能中发挥重要的作用。②神经系统作用于皮肤创伤愈合的不同阶段,能够调节血管再生,促进相关生长因子及神经递质释放,和不同类型细胞协同作用从而促进皮肤创面愈合;因此,研究神经系统作用的潜在机制成为促进皮肤创伤愈合的有力靶点。

BACKGROUND:Skin wound repair is an extremely complex process.The nervous system plays an important role in regulating wound repair and scar healing.OBJECTIVE:To review the role of the nervous system in the process of skin wound repair,including the roles of related factors and various cells in the repair of skin injury.METHODS:The PubMed and CNKI databases were searched with the key words of“skin wound healing,nervous system,nerve regeneration,growth factor”in English and“skin wound healing,skin innervation,neuropeptide,growth factor,cell synergy”in Chinese.The time range of literature search was from 2003 to 2024,and 83 documents were finally included and analyzed.RESULTS AND CONCLUSION:(1)The skin is densely innervated by autonomic and sensory nerves,and there is growing evidence that the cutaneous nervous system is not only responsible for transmitting sensory information to the central nervous system,but also plays an important role in a variety of skin functions,including wound healing.(2)The nervous system acts on different stages of skin wound healing,which can regulate revascularization,promote the release of related growth factors and neurotransmitters,and cooperate with different types of cells to promote skin wound healing.Therefore,research on the underlying mechanisms of the nervous system has become a powerful target to promote skin wound healing.
