Multimodal imaging of the course of retinal changes in acute posterior multifocal placoid pigment epitheliopathy with bilateral retinal detachment: a case report

open access: yesBMC Ophthalmology, 2022
Background To report a rare case of acute posterior multifocal placoid pigment epitheliopathy (APMPPE) with a combination of serous retinal detachment, papilledema, and retinal vasculitis.

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

open access: yesFEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

PNPLA6 regulates retinal homeostasis by choline through phospholipid turnover

open access: yesNature Communications
Although mutations in human patatin-like phospholipase PNPLA6 are associated with hereditary retinal degenerative diseases, its mechanistic action in the retina is poorly understood.

Lipopolysaccharide enhances HSV-1 replication and inflammatory factor release in the ARPE-19 cells

open access: yesHeliyon, 2022
Purpose: During acute retinal necrosis (ARN), retinal pigment epithelial (RPE) cells could be stimulated by both herpes simplex virus (HSV) and lipopolysaccharide (LPS).

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

open access: yesFEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Retinal Pigment Epithelial Cells Release Inhibitors of Neovascularization

open access: yesOphthalmology, 1987
Human retinal pigment epithelial (RPE) cells in culture were found to release a substance (or substances) that causes the regression of new blood vessels on the chick embryonic yolk sac and inhibits proliferation of fetal bovine aortic endothelial cells and human retinal microvessel endothelial cells in vitro.

Ocular immune privilege and retinal pigment epithelial cells

open access: yesJournal of Leukocyte Biology, 2023
AbstractThe ocular tissue microenvironment is immune-privileged and uses multiple immunosuppressive mechanisms to prevent the induction of inflammation. The retinal pigment epithelium plays an essential role in ocular immune privilege. In addition to serving as a blood barrier separating the fenestrated choriocapillaris from the retina, the retinal ...

Multifunctional Catechol‐Functionalized Cellulose Hydrogels for the Minimally Invasive Treatment of Acute Optic Nerve Injuries

open access: yesAdvanced Healthcare Materials, EarlyView.
Catechol‐functionalized cellulose hydrogels are developed as injectable, bioadhesive platforms for retinal neuroprotection. The hydrogels exhibit tunable rheological and mechanical properties, strong tissue adhesion, and sustained antioxidative activity.

AA344 and AA345 antibodies recognize the microtubule network in human cells by immunofluorescence

open access: yesAntibody Reports, 2019
The recombinant antibodies AA344 and AA345 detect the microtubule network by immunofluorescence in interphase and mitotic glutaraldehyde-fixed Retinal Pigment Epithelial cells (hTert-RPE1).

Hamartomas of the Retina and Optic Disc

open access: yesTürk Oftalmoloji Dergisi, 2022
Hamartomas are local malformation of cells that demonstrate abnormal proliferation in the area where they are normally present. Retinal and optic disc hamartomas include astrocytic hamartoma, congenital hypertrophy of the retinal pigment epithelium ...
