角膜神经调控眼表微环境的研究进展

Advances in corneal nerve regulation of ocular surface microenvironment

摘要:

角膜是眼前段透明的外层结构，由高密度的神经组织支配。在角膜神经支配过程中，三叉神经节起源的角膜神经穿过上皮层和基质层中不同类型的角膜细胞。角膜基质细胞、上皮细胞、免疫细胞等多种细胞和角膜神经之间发生密切的相互作用，共同维持角膜微环境稳态。此外，角膜神经参与许多眼表疾病的发生发展过程。角膜神经释放多种活性肽物质，参与调控角膜感觉、维持上皮完整性和增殖、促进伤口愈合及调控角膜局部炎症和免疫反应等。本文对角膜神经在眼表微环境调控作用的研究进展进行综述，为角膜神经相关疾病的研究及治疗提供新的思路。

Abstract:

The cornea is a transparent outer layer of the anterior eye segment, innervated by a high density of neural tissue. In the process of corneal innervation, trigeminal ganglion originated corneal nerves traverse different types of corneal cell in the epithelial and stromal layers. Corneal stromal cells, epithelial cells, immune cells, and other cells interact closely to maintain corneal microenvironmental homeostasis. In addition, corneal nerves is associated with the occurrence and development of many ocular surface diseases. Corneal nerves release various active peptides that regulate corneal sensation, maintain epithelial integrity and proliferation, improve wound healing, and manage local inflammation and immune response. This article reviews the advances in the corneal nerve regulation of the ocular surface microenvironment, providing some new ideas for the further study and treatment of corneal nerve-associated diseases.
