神经是皮肤感觉和体温调节等生理功能的基础,也通过多种机制调控创伤再生和瘢痕愈合等病理过程。尽管失神经支配的皮肤伤口能够愈合,但神经通过启动神经源性炎症反应和神经营养作用增加伤口周围组织的血供,促进成纤维细胞和角质形成细胞增殖和Ⅰ型、Ⅲ型胶原的表达,与免疫系统的相互作用和释放神经肽等机制促进皮肤伤口愈合。如果各种参与修复细胞、细胞外基质、神经血管和皮肤附属器能有机装配则再生修复,否则瘢痕愈合。神经自身主要在创伤修复早期和瘢痕塑形期通过轴突的生长修复,其生长速度明显较肉芽组织形成和瘢痕化慢。而且,不同神经纤维的轴突生长也不完全相同。外源性神经肽可促进难愈性伤口愈合,神经肽拮抗剂或高选择神经切断等失神经措施可减轻瘢痕增生。因此,了解神经和各种修复成分在创伤再生修复与瘢痕愈合中的作用和调控机制,有助于寻找促进皮肤和周围神经损伤再生修复的方法。
神經是皮膚感覺和體溫調節等生理功能的基礎,也通過多種機製調控創傷再生和瘢痕愈閤等病理過程。儘管失神經支配的皮膚傷口能夠愈閤,但神經通過啟動神經源性炎癥反應和神經營養作用增加傷口週圍組織的血供,促進成纖維細胞和角質形成細胞增殖和Ⅰ型、Ⅲ型膠原的錶達,與免疫繫統的相互作用和釋放神經肽等機製促進皮膚傷口愈閤。如果各種參與脩複細胞、細胞外基質、神經血管和皮膚附屬器能有機裝配則再生脩複,否則瘢痕愈閤。神經自身主要在創傷脩複早期和瘢痕塑形期通過軸突的生長脩複,其生長速度明顯較肉芽組織形成和瘢痕化慢。而且,不同神經纖維的軸突生長也不完全相同。外源性神經肽可促進難愈性傷口愈閤,神經肽拮抗劑或高選擇神經切斷等失神經措施可減輕瘢痕增生。因此,瞭解神經和各種脩複成分在創傷再生脩複與瘢痕愈閤中的作用和調控機製,有助于尋找促進皮膚和週圍神經損傷再生脩複的方法。

Nerve is the foundation of the physiological function such as the skin feeling and thermoregulation, and also regulates the re-generation and scar healing of skin wound by multiple mechanisms. Though the denervated skin wound can heal spontaneously, the nerve might accelerate wound healing by activating the neurogenic inflammation and nerve trophism, increasing the blood supply around the wound, promoting the proliferation of fibroblasts and keratinocytes, stimulating the expression of collagen I and III, and interacting with im-mune system and releasing neuropeptides. If all kinds of repair cells, extracellular matrix, nerve, blood vessel and cutaneous appendages as-semble organically, the skin wound regenerates, and otherwise the scar heals. The nerve axon growth occurs mainly in the early stage of the wound healing and the scar rebuilding process, and the nerve growth rate is obviously slower than the granulation tissue formation and cica-trization. Furthermore, the axon growth of different nerve fibers are not entirely the same. The exogenous neuropeptides might promote the wound repair and the nerve regeneration. The antagonist of the neuropeptides or high selective nerve abscission might reduce the scar hyper-plasia. Therefore, it contribute to find methods to promote the regeneration of skin wound and peripheral nerve injury by understanding the effects and regulatory mechanism of both nerve and various repair elements in regeneration or scar healing of skin wound.
