What this research studies

This project maps the signals exchanged between resident immune cells, other corneal cells, and the sensory nerves that come from the trigeminal ganglia. Researchers will identify specific ligand–receptor pairs and neurotrophic factors produced by different corneal cell types that support nerve survival and regeneration. Work will combine analysis of corneal tissues and cells with laboratory models to see how loss of these factors leads to nerve degeneration in neurotrophic keratitis. The goal is to pinpoint targets that could become new diagnostics or treatments to restore corneal sensation.

Who could benefit from this research

Good fit: Ideal candidates would be people with neurotrophic keratitis or documented corneal nerve damage and reduced corneal sensation.

Not a fit: People without corneal nerve disease or whose eye problems are due to non-neural causes are unlikely to directly benefit from this research.

Why it matters

Potential benefit: If successful, this work could lead to new tests and therapies that restore corneal sensation and reduce vision loss from neurotrophic keratitis.

How similar studies have performed: Prior studies show corneal nerves release factors that support the surface of the eye, but mapping immune–nerve ligand–receptor interactions in NK is a relatively new and developing approach.
