Herpes Simplex Virus-1 (HSV-1) infections in the eye often originate in the cornea before assuming a latent state in the trigeminal ganglion. During primary infection and upon injury or reactivation, HSV-1 can lead to significant corneal damage. Nanoparticles (NPs) are an emerging strategy for drug delivery to the cornea because they improve the long-term release of anti-HSV-1 drugs, such as nucleoside analogues. Acyclovir, ganciclovir, and valacyclovir have been successfully delivered using both polymer and lipid-based NPs in vitro. Solid silica dioxide NPs have been used to deliver the cathelicidin, LL-37, which prevented HSV-1 infection in corneal epithelial cells. Iron oxide nanoparticles have also been adapted to deliver an anti-HSV-1 DNA vaccine that successfully reduced corneal opacity and HSV-1 markers in a mouse model. Overall, NPs show promise as a delivery method for anti-HSV-1 strategies.
