What this research studies

If you have diabetic retinopathy, this project is developing new STING-blocking compounds that could become treatments. Researchers will test these compounds in cells and animal models to see if they stop DNA-driven inflammation, reduce immune cell buildup in the retina, and prevent blood-retinal barrier leakage. The team has shown in earlier work that blocking STING can lower retinal inflammation and leakage in models of eye disease. If the compounds look safe and effective, they could move toward human safety studies and future clinical trials.

Who could benefit from this research

Good fit: People with diabetic retinopathy—especially those whose vision does not improve with anti‑VEGF injections—are the most likely candidates for future trials.

Not a fit: People without diabetic eye disease or whose vision loss is due to unrelated causes are unlikely to benefit from this research.

Why it matters

Potential benefit: Could lead to new treatments that lower retinal inflammation, reduce leakage, and help preserve vision for people with diabetic retinopathy.

How similar studies have performed: Preclinical studies show that blocking STING can reduce retinal inflammation and leakage in animal models, but using bifunctional STING inhibitors as potential therapies is a new approach.
