Improvement of corneal barrier function by the P2Y(2) agonist INS365 in a rat dry eye model.

In a rat dry eye model, the P2Y(2) agonist INS365 was found to improve surface health, based on increases in tear fluid secretion, corneal epithelial resistance, and release of glycoprotein-containing moieties from goblet cells. These effects suggest that INS365 is a potential therapeutic agent for use in the treatment of dry eye syndrome.
