Gene therapy offers potential for treating corneal diseases. Research reviews corneal gene delivery methods, challenges, and preclinical successes in graft rejection and keratitis.

Area of Science:

  • Ophthalmology
  • Gene Therapy
  • Corneal Diseases

Background:

  • Gene therapy can correct inherited and acquired corneal diseases.
  • The cornea's accessibility, transparency, and immune privilege facilitate gene delivery.
  • Early studies focused on intraocular administration and gene expression patterns.

Purpose of the Study:

  • This review focuses on corneal gene delivery systems and administration methods.
  • It examines preclinical studies on preventing and treating corneal conditions.
  • Considerations for animal model selection in corneal gene therapy research are discussed.

Main Methods:

  • Review of existing literature on corneal gene delivery systems.
  • Analysis of intraocular administration modes and their outcomes.

Related Experiment Videos

  • Evaluation of preclinical study results for various corneal diseases.

    • Main Results:

    • Topical gene transfer faces challenges due to tear flow and epithelial barriers, necessitating invasive methods.
    • DNA vaccination, RNA interference, and gene transfer modulated the corneal microenvironment.
    • Preclinical studies showed positive outcomes for corneal graft rejection, neovascularization, haze, and herpetic stromal keratitis.

    Conclusions:

    • Corneal gene therapy holds promise for treating a range of corneal conditions.
    • Future opportunities include investigating more diseases and utilizing advanced, safer vectors with reduced immunogenicity and prolonged gene expression.
