Abstract

Aging of the retinal pigment epithelium (RPE) leads to a gradual decline in RPE homeostasis over time, significantly impacting retinal health. Understanding the mechanisms underlying RPE aging is crucial for elucidating the background in which many age-related retinal pathologies develop. In this study, we compared the transcriptomes of young and aged mouse RPE and observed a marked upregulation of immunogenic, proinflammatory, and oxidative stress genes in aging RPE. Additionally, aging RPE exhibited dysregulation of pathways associated with visual perception and extracellular matrix production. Research on aging in post-natal quiescent RPE is hindered by the absence of relevant

Research summary

The paper claims that aging leads to significant transcriptomic changes in the retinal pigment epithelium, which may contribute to age-related retinal pathologies. This research is relevant as it investigates the underlying mechanisms of aging in a specific tissue, potentially informing strategies to address age-related diseases.
