Widespread subclinical cellular changes revealed across a neural-epithelial-vascular complex in choroideremia using adaptive optics

Communications Biology, 2022
The in vivo pathogenesis of the blinding retinal degeneration choroideremia is visualized, which reveals enlarged and area-disrupted retinal pigment epithelial cells, providing evidence for polymegathism in choroideremia.

Preclinical Evaluation of a Cell-Based Gene Therapy Using the Sleeping Beauty Transposon System in Choroidal Neovascularization

Molecular Therapy: Methods & Clinical Development, 2019
Age-related macular degeneration (AMD) is a progressive retinal disorder characterized by imbalanced pro- and antiangiogenic signals. The aim of this study was to evaluate the effect of ex vivo cell-based gene therapy with stable expression of human ...

A defined subset of clonal retinal stem cell spheres is biased to RPE differentiation

iScience, 2021
Summary: Retinal stem cells (RSCs) are rare pigmented cells found in the pigmented ciliary layer of the mammalian retina. Studies show that RSCs can replicate to maintain the stem cell pool and produce retinal progenitors that differentiate into all ...

Hydrogen peroxide enhances transforming growth factor beta-2 induced epithelial–mesenchymal transition of ARPE-19 cells

Beni-Suef University Journal of Basic and Applied Sciences, 2023
Background In the pathophysiology of the retina, the epithelial–mesenchymal transition and oxidative stress play key roles. To find a relationship between oxidative stress and diabetic retinopathy or proliferative retinopathy, we used an in-silico ...

Biochemical adaptations of the retina and retinal pigment epithelium support a metabolic ecosystem in the vertebrate eye

eLife, 2017
Here we report multiple lines of evidence for a comprehensive model of energy metabolism in the vertebrate eye. Metabolic flux, locations of key enzymes, and our finding that glucose enters mouse and zebrafish retinas mostly through photoreceptors ...

Detection of Retinal Pigment Epithelium-Specific Antibody in iPSC-Derived Retinal Pigment Epithelium Transplantation Models

Stem Cell Reports, 2017
Summary: Antibody-mediated rejection is characterized by donor-specific antibody produced by B cells. However, to our knowledge, B cell invasion and antibody in the inflamed retina after transplantation of retinal pigment epithelial (RPE) cells has not ...
