What this research studies

If you have recurring herpes of the eye, this project aims to understand why those infections sometimes cause repeated inflammation and scarring that can threaten vision. The team uses mouse models to study a protein called SARM1 and how nerve cells and immune cells talk to each other during infection. They will test whether lacking SARM1 changes how the virus is controlled and how the immune response develops over time. This work could point to new ways to stop recurrent corneal damage from herpes.

Who could benefit from this research

Good fit: People with a history of recurrent herpes simplex infection of the cornea (herpes stromal keratitis) who could participate in future clinical work, likely near the University of Pittsburgh, would be the most relevant candidates.

Not a fit: People without HSV-1 corneal disease or whose vision loss is caused by non-herpetic conditions are unlikely to benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could point to new targets to prevent recurrent herpes-related corneal scarring and help preserve vision.

How similar studies have performed: Related animal studies show nerve–immune interactions can change corneal disease outcomes, but focusing on SARM1 in HSK is a relatively new approach.
