MicroRNAs of the RPE are essential for RPE differentiation and photoreceptor maturation [PDF]

Development, 2015
Dysfunction of the retinal pigmented epithelium (RPE) results in degeneration of photoreceptors and vision loss and is correlated with common blinding disorders in humans. Although many protein-coding genes are known to be expressed in RPEs and important for their development and maintenance, virtually nothing is known about the in vivo roles of non ...

Antenna array with switching scanning in elevation plane

Физика волновых процессов и радиотехнические системы, 2021
It is known that the most reliable communication in hard-to-reach places such as the Arctic, Tundra, Taiga is satellite communication [1-5]. Therefore, for satellite communications, it is necessary to develop your own antenna arrays.

Replacement of the RPE monolayer [PDF]

Eye, 2009
There are numerous scenarios in which replacing the diseased RPE monolayer is an attractive but as yet unrealised goal. The proof of concept that vision can be improved by placing a healthy neuroretina onto a different, healthy, underlying RPE layer is demonstrated in patch graft transplantations.

Immunological aspects of RPE cell transplantation.

Progress in retinal and eye research, 2021
Retinal pigment epithelial (RPE) cells have several functions, including support of the neural retina and choroid in the eye and immunosuppression. Cultured human RPE cells directly suppress inflammatory immune cells. For instance, they directly suppress

Nrf2 overexpression rescues the RPE in mouse models of retinitis pigmentosa

JCI Insight, 2021
Nrf2, a transcription factor that regulates the response to oxidative stress, has been shown to rescue cone photoreceptors and slow vision loss in mouse models of retinal degeneration (rd). The retinal pigment epithelium (RPE) is damaged in these models,

Photoreceptor cells and RPE contribute to the development of diabetic retinopathy

Progress in retinal and eye research, 2020
Diabetic retinopathy (DR) is a leading cause of blindness. It has long been regarded as vascular disease, but work in the past years has shown abnormalities also in the neural retina.
