Epinephrine, but not dexamethasone, induces apoptosis in human retinal pigment epithelium cells in vitro: Possible implications on the pathogenesis of central serous chorioretinopathy

open access: yesPhilippine Journal of Ophthalmology, 2004
Objective: The pathogenesis of central serous chorioretinopathy is poorly understood. It is believed to be due to dysfunction of the retinal pigment epithelium and/or choroid, and has been associated with elevated levels of epinephrine and administration

Prime editing in neuropsychiatric disorders: From mutation‐specific target selection to clinical translation

open access: yesNeuroprotection, EarlyView.
Abstract Prime editing, a novel clustered regularly interspaced short palindromic repeats (CRISPR)‐based technology, fuses a reverse transcriptase (RT) to an engineered CRISPR‐associated protein 9 (Cas9) and uses a prime editing guide RNA (pegRNA)‐encoded template.

Staging concept for aging management: Definition, mechanism, and coping strategies

open access: yesVIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Characterisation of neural progenitors from the adult retina and ciliary epithelium

open access: yes, 2009
The mammalian central neural retina (CNR) lacks the capability to regenerate, a phenomenon retained by lower vertebrates. However, retinal stem cells have been isolated from the ciliary epithelium of the mammalian retina.

Mesopic microperimetry in Stargardt disease: Application and reliability

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Mesopic microperimetry (mMP) is a promising functional endpoint in clinical trials for Stargardt disease type 1 (STGD1). This study evaluated the test–retest variability of mMP and influencing factors, which is essential for ensuring reliability in future STGD1 trials.

Norbixin Protects Retinal Pigmented Epithelium Cells and Photoreceptors against A2E-Mediated Phototoxicity In Vitro and In Vivo.

open access: yesPLoS ONE, 2016
The accumulation of N-retinylidene-N-retinylethanolamine (A2E, a toxic by-product of the visual pigment cycle) in the retinal pigment epithelium (RPE) is a major cause of visual impairment in the elderly.
