Thymosin Beta‑4 for Acanthamoeba keratitis

Thymosin Beta-4: A novel treatment for Acanthamoeba keratitis

NIH-funded research Clemson University · NIH-11249189

This project tests whether Thymosin β4 can help treat Acanthamoeba keratitis, an often contact-lens–related eye infection that can threaten vision.

What this research studies

Researchers will use lab-grown 3D corneal cell models and cultures of Acanthamoeba castellanii to see how Thymosin β4 affects both the parasite and the cornea. They will measure parasite survival in active amoebae and resistant cysts, corneal cell death, protease activity, and inflammatory signals. The team will test whether Thymosin β4 reduces tissue damage and inflammation while being safe for corneal cells. Promising results would support follow-up animal or human studies toward a new treatment.

Who could benefit from this research

Good fit: People with current or recent Acanthamoeba keratitis—especially contact lens users with corneal infection—would be the eventual candidates for treatments developed from this work.

Not a fit: Patients without Acanthamoeba infection or those with irreversible, late-stage corneal damage already requiring transplant may not benefit directly from this early-stage work.

Why it matters

Potential benefit: If successful, this could lead to a therapy that both limits the parasite and protects the cornea, reducing vision loss and the need for corneal transplants.

How similar studies have performed: Thymosin β4 has shown benefits for corneal healing and reduced inflammation in other eye conditions, but applying it specifically to Acanthamoeba infections is a new approach.
