| description | Ocular cells like, retinal pigment epithelium (RPE) is a highly specialized pigmented
monolayer of post-mitotic cells, which is located in the posterior segment of the eye between
neuro sensory retina and vascular choroid. It functions as a selective barrier and nourishes
retinal visual cells. As a result of high-level oxygen consumption of retinal cells, RPE cells
are vulnerable to chronic oxidative stress and an increased level of reactive oxygen species
(ROS) generated from mitochondria. These oxidative stress and ROS generation in retinal cells
lead to RPE degeneration. Various sources including mtDNA damage could be an important fac-
tor of oxidative stress in RPE. Gene therapy and mitochondrial transfer studies are emerging
fields in ocular disease research. For retinal degenerative diseases stem cell-based transplan-
tation methods are developed from basic research to preclinical and clinical trials. Transla-
tional research contributions of gene and cell therapy would be a new strategy to prevent,
treat and cure various ocular diseases. This review focuses on the effect of oxidative stress in ocular cell degeneration and recent translational researches on retinal degenerative dis-
eases to cure blindness. |
