Retinal cell transplantation in retinitis pigmentosa

open access: yesTaiwan Journal of Ophthalmology, 2021
Retinitis pigmentosa is the most common hereditary retinal disease. Dietary supplements, neuroprotective agents, cytokines, and lately, prosthetic devices, gene therapy, and optogenetics have been employed to slow down the retinal degeneration or improve light perception.

Retinal Plasticity [PDF]

open access: yesInternational Journal of Molecular Sciences, 2022
Brain plasticity is a well-established concept designating the ability of central nervous system (CNS) neurons to rearrange as a result of learning, when adapting to changeable environmental conditions or else while reacting to injurious factors. As a part of the CNS, the retina has been repeatedly probed for its possible ability to respond plastically

Retinitis pigmentosa and retinal oedema. [PDF]

open access: yesBritish Journal of Ophthalmology, 1978
Twenty-five patients with retinitis pigmentosa and retinal leakage were investigated. Oedema was present in dominant and X-linked inherited disease and is likely to be present in recessive disease as well. We suggest that this might be a general response seen in many types of tapeto-retinal degeneration to actively degenerating photoreceptors or ...

Retinal Prosthesis [PDF]

open access: yesIEEE Transactions on Biomedical Engineering, 2012
Retinal prosthesis has been translated from the laboratory to the clinic over the past two decades. Currently, two devices have regulatory approval for the treatment of retinitis pigmentosa. These devices provide partial sight restoration and patients use this improved vision in their everyday lives.

Retinal imaging in inherited retinal diseases [PDF]

open access: yesAnnals of Eye Science, 2020
Inherited retinal diseases (IRD) are a leading cause of blindness in the working age population. The advances in ocular genetics, retinal imaging and molecular biology, have conspired to create the ideal environment for establishing treatments for IRD, with the first approved gene therapy and the commencement of multiple therapy trials.

Crystal Structure of the N112A Mutant of the Light-Driven Sodium Pump KR2

open access: yesCrystals, 2020
The light-driven sodium pump KR2, found in 2013 in the marine bacteria Krokinobacter eikastus, serves as a model protein for the studies of the sodium-pumping microbial rhodopsins (NaRs). KR2 possesses a unique NDQ (N112, D116, and Q123) set of the amino
