Capsaicin-Induced Corneal Sensory Denervation and Healing Impairment Are Reversed by NGF Treatment

Abstract

In this study, we show that an alteration in the NGF pathway is responsible for a delay in corneal healing in an animal model of sensory denervation. Moreover, we show that NGF eye drop administration modulates corneal innervation, epithelial cell healing, and corneal stem cells. These findings may trigger further research on the role of the NGF pathway in limbal stem cell deficiency.
