Combined nanoparticle treatment may reverse age-related dry eye by reducing cell aging and oxidative stress

Updated

Abstract

A polypeptide-based eye drop significantly improved corneal permeability and reduced oxidative stress in models of dry eye disease.

  • The treatment combines quercetin and superoxide dismutase in a nanocarrier to enhance therapeutic efficacy.
  • Quercetin functions as an anti-aging agent and aids in the effective delivery of superoxide dismutase.
  • The eye drop formulation showed improved outcomes compared to free superoxide dismutase.
  • Treatment led to restored lacrimal gland function and reversal of key symptoms associated with dry eye disease.
  • It effectively reduced activity associated with age-related cellular senescence in dry eye disease models.
