Preclinical Models for Studying Fuchs Endothelial Corneal Dystrophy.

Area of Science:

• Ophthalmology
• Genetics
• Cell Biology

Background:

• Fuchs Endothelial Corneal Dystrophy (FECD) is a prevalent corneal disease causing endothelial cell loss and vision impairment.
• It is a leading cause for corneal transplantation worldwide, particularly in older adults.
• The exact etiology is unknown, but likely involves genetic and environmental factors.

Purpose of the Study:

• To review the proposed genetic and molecular pathologies of FECD.
• To discuss the impact of guttata, endothelial-to-mesenchymal transition, senescence, and oxidative stress.
• To summarize and evaluate preclinical models for FECD research.

Main Methods:

• Review of existing literature on FECD.
• Analysis of proposed genetic and molecular mechanisms.
• Summary of in vitro, ex vivo, and in vivo preclinical models.

Main Results:

• FECD pathology involves extracellular matrix deposition, endothelial-to-mesenchymal transition, cell senescence, and oxidative stress.
• Various preclinical models (cell, tissue, animal) are utilized to study FECD.
• Each model presents unique benefits and challenges for research.

Conclusions:

• Understanding FECD mechanisms requires integrating clinical and preclinical findings.
• Preclinical models are crucial for developing regenerative therapies for FECD.
• Further research into FECD pathogenesis and modeling is essential.
