Recent advances in neurotrophic factors promoting corneal epithelial wound healing / 眼科新进展

ABSTRACT

Neurotrophic factors are a species of protein molecules,which produced by tissue supplied by nerve and astrocytes and necessary for neuronal growth and survival.Neurotrophic factors play an important role in the development and physiological function of the nervous system.It can promote neurons growth and development,and keep neurons functional integrity.Except for the regulation and functionality action on the innervated tissue,neurotrophic factors play an important neurotrophic role for the tissue physiology,growth and metabolism.The cornea is the highest density of nerve fibers.Abundant nerve fibers enhance the sensory function.In addition,the nerve fibers can also secrete various nutrition and regulatory factors to keep the physiological function and regeneration.In recent years,the research of neurotrophic factors on promoting corneal epithelial wound healing has made great progress.This article reviews the recent advances in different neurotrophic factors promoting the repair of corneal epithelial injury.
