Photoreceptor Cell Survival

Molecular classification
Cellular Process, Neuroepithelial Cells
01

Overview

Photoreceptor cell survival refers to the maintenance and preservation of photoreceptor cells—specialized neuroepithelial cells in the retina responsible for converting light into neural signals. Their degeneration leads to irreversible vision loss, as seen in diseases like retinitis pigmentosa (RP) and age-related macular degeneration. Multiple molecular pathways influence photoreceptor cell survival, including oxidative stress, calcium ion imbalance, high cGMP levels, endoplasmic reticulum stress, inflammation, and metabolic alterations. Therapeutic strategies aim at promoting or preserving photoreceptor survival through antioxidants, gene therapy, and oxygen modulation.
