RESUMO
Although initial herpes simplex virus (HSV) infections of the cornea are relatively easily treated, recurrent infections following reactivation of latent virus in the sensory ganglion cells are more difficult to treat. Untreated infections may result in severe consequences, including corneal scarring, glaucoma, and encephalitis. To develop such treatments, an experimental in vivo model was needed in which HSV can be applied directly to trigeminal ganglion cells. We have previously developed such a model to examine the mechanisms of HSV spread from trigeminal neurons to corneal epithelial cells. The current paper describes in detail the technical steps required for implementation of that model. Immunocytochemistry and electron microscopy have been used to validate the efficacy of the described procedures. This technique will be useful for future in vivo studies of neurotrophic viral infections of trigeminal ganglion cells.
