Reducing cell stress in the eye to block herpes infections

Alleviation of ER stress as a translational strategy to curb ocular viral infections

NIH-funded research University of Illinois at Chicago · NIH-11261220

What this research studies

This project focuses on herpes simplex virus infections of the cornea that can lead to vision loss. Scientists found a host protein called CREB3 in the cell's endoplasmic reticulum helps the virus replicate, and they are using a chemical chaperone (sodium 4-phenylbutyrate, Na-PBA) to lower ER stress and reduce CREB3. They have supporting data from mouse experiments showing antiviral effects and topical safety in animals. The team is working on translating these findings toward a topical treatment while addressing formulation and sodium-related safety issues.

Who could benefit from this research

Good fit: Ideal candidates would be people with or at risk for herpes simplex infections of the cornea (herpetic keratitis).

Not a fit: Patients with eye disease caused by non-herpes pathogens or with irreversible structural eye damage are unlikely to benefit from this approach.

Why it matters

Potential benefit: If successful, this work could lead to a new topical antiviral approach for herpes-related eye infections that may work when current drugs fail.

How similar studies have performed: Preclinical work in cells and mice has shown promise for reducing ER stress to limit viral replication, but this mechanism is novel and lacks human trial results so far.
