Gene transfer technology : a tool for studying gene function and role in corneal pathogenesis [abstract]

Abstract

Transforming growth factor β (TGFb) is associated with many corneal pathologies, diseases and dystrophies. The function of TGFb in adult corneas cannot be studied using conventional transgenic approach because TGFb1 and TGFb2 deficient transgenic animals suffer multiple inflammatory diseases, severe developmental defects, and death by 3-4 weeks of age. This study tested the hypothesis that selective tissue-targeted gene transfer approaches will permit examination of TGFb gene function in the adult cornea without altering TGFb expression in vital organs.
