Summary: Pathologic angiogenesis in eye diseases leading to blindness can be attributed to cell senescence, as demonstrated by the bioinformatics study conducted by Crespo-Garcia, Tsuruda, and Dejda. Their findings were validated in human and mouse retina models, where clearance of senescent cells effectively suppressed neovessel growth.

Summary: The iron-binding nanoscale Prussian blue analogue CaPB effectively prevents RPE degeneration and subsequent photoreceptor cell degeneration, showing superior therapeutic outcomes in mice upon a single intravitreal injection. The findings suggest that CaPB nanoparticles protect against RPE degradation by inhibiting ferroptotic cell fate, making them promising for future clinical treatment of retinal diseases involving iron-dependent ferroptosis.

Summary: This study aimed to model the effects of chloroquine on the retinal pigment epithelium in vivo and investigate the impact of mild chloroquine treatment on lysosome function and turnover. The research found that low-dose chloroquine treatment inhibits lysosome reformation, leading to a gradual depletion of lysosomes' ability to interact with cargo-carrying vacuoles and degrade their content. The accumulation of pro-cathepsin D and LAMP1 reflects the inhibition of normal turnover of lysosomal constituents and possibly lysosomes themselves. Understanding the mechanisms underlying lysosome reformation may contribute to the development of new treatments for chloroquine-induced retinopathy.

Summary: It has been found that the Klotho gene can suppress aging when overexpressed in mice and accelerate aging when deleted. This study demonstrates that Klotho regulates cell viability, mitochondrial gene expression and activity, as well as RPE/retinal resistance to oxidative stress. These findings highlight the important role of Klotho in aging and retinal health.

Summary: Research has revealed that zebrafish RPE has strong intrinsic regenerative potential, with elements of immune response identified as critical mediators in the regeneration process. Macrophage/microglia cells are responsive to RPE damage and essential for the timely progression of regenerative response.

Summary: This study confirms the dysfunction of the retinal pigment epithelium (RPE) in patients with neurofibromatosis type 1 (NF1), characterized by a lower dark trough (DT) and a corresponding higher light peak (LP)/DT ratio. This pattern may be due to a dysregulation of melanocytogenesis, leading to disrupted calcium ion flux and abnormal polarization of the RPE.

Summary: The retinal pigment epithelium is crucial for visual functions, but damage to its structure and function can lead to various retinopathies with no cure currently available. Understanding the development, function, and pathobiology of the retinal pigment epithelium is essential for preventing and treating retinopathies. This review discusses potential strategies for treatment and provides new perspectives for future research in this field.

Summary: In this study, we investigated the mechanisms and kinetics of pigment-related drug retention using isolated melanin particles, melanosomes, and pigmented cells. Our results showed that the release of drugs from melanin and melanosomes was faster compared to pigmented cells. Additionally, our simulations revealed that drug retention in cells was prolonged with decreasing drug permeability in melanosomal membranes and increasing melanin content in cells.

Summary: This study demonstrates that human RPE cell lines (ARPE-19) can be cultured on ultrathin suspended electrospun nanofibre scaffolds (ENS) composed of hydrophobic polymer polyacrylonitrile (PAN) and a water-soluble aliphatic diamine, without or with fluocinolone acetonide (FA) treatment. The cells survived and maintained their morphology for up to 150 days with FA-treated ENS, showing an epithelial phenotype with biomarkers critical for retinal characteristics. This technique has potential for subretinal transplantation.

Summary: As the world ages, the number of age-related diseases, particularly those related to retinal pigment epithelium (RPE) degeneration, has increased. Photobiomodulation (PBM), a non-invasive treatment using red and near-infrared light, has shown potential as a new treatment for ocular diseases. Recent studies have demonstrated its antioxidant effect, making it a promising approach to cure RPE degeneration.

Summary: Glucocorticoids are commonly used drugs to treat retinal diseases, but the transcriptional regulations induced by GR and MR activation in RPE cells are not well understood. The study found that in the human eye, cortisol is the main ligand for GR and MR, and genes regulated by aldosterone and cortisol + RU-486 can mimic an imbalance toward MR activation. This activation in RPE cells may contribute to retinal pathology.

Summary: Dry age-related macular degeneration (AMD) is a common eye disease with no current treatment options. Using microcarrier technology for cell culture allows efficient large-scale production of therapeutic retinal pigmented epithelial cells, fulfilling the treatment demands.

Summary: This study analyzed the molecular changes of retinal pigment epithelium (RPE) cells during aging through quantitative proteomic analysis. The findings suggest that protein ubiquitination related to RNF123 and RNF149 plays a crucial role in protecting RPE cells from oxidative damage.

Summary: Research has shown that the addition of Y-27632 in vitro can suppress apoptosis, promote cell adhesion and proliferation, and increase the survival rate of transplants. In vivo experiments with human iPS-RPE cell transplantation into monkey eyes showed no obvious retinal toxicity caused by Y-27632.

Summary: The study found that the combined use of 5-FU and LMWH treatment did not improve the primary success rate of vitrectomy or decrease the number of patients who underwent vitreoretinal reoperations. However, in patients with PVRC before intervention, this treatment was effective in reducing the risk of postoperative PVR.
