In a study published in the journal of Genes & Diseases, researchers from Sichuan Provincial People’s Hospital revealed these degenerative processes and, importantly, identifies potential therapeutic targets. The study sequenced the RNA of approximately 0.3 million single cells from the human RPE and choroids across two regions at seven different ages. This detailed analysis has unveiled regional and age-specific differences within the human RPE and choroid. Such cellular interactions underscore the extensive connectivity networks between the RPE and different choroid cell types. Additionally, the research team discovered that specific transcription factors and their target genes change during aging. Notably, they identified the gene ELN as a potential candidate for mitigating RPE degeneration and choroidal structure deterioration during aging, offering promising avenues for interventions in retinal diseases.

In conclusion, this study offers a comprehensive single-cell transcriptomic atlas of the human RPE and choroid across different regions and ages. It provides a wealth of information about the gene signatures of these integral components of the visual system. Moreover, the identification of ELN as a candidate for combating degeneration of choroidal and RPE structures paves the way for targeted interventions for anti-aging or ocular disease therapy.

This novel research has the potential to revolutionize our understanding of the human visual support system. It stands as a valuable resource for future studies into distinct gene-expression signatures and lays a solid foundation for future research into the functions of RPE and choroid genes.
