Moreover, an elegant study by Chucair-Elliott et al. [52] reported that IL-6 was increased in the murine cornea after herpes simplex virus (HSV) infection, and that IL-6 suppression by either neutralizing Ab or dexamethasone reduced corneal nerve regression, thereby preserving sensation in HSV keratitis. The gene discussed is IL6; the disease is herpes simplex virus keratitis.
