Microglia inhibit photoreceptor cell death and regulate immune cell infiltration in response to retinal detachment

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Photoreceptor cell death resulting from retinal detachment (RD) causes significant visual loss. While the immune system is activated during RD, its role is still unclear.

The Vitamin B₁₂-Dependent Photoreceptor AerR Relieves Photosystem Gene Repression by Extending the Interaction of CrtJ with Photosystem Promoters

mBio, 2017
Purple nonsulfur bacteria adapt their physiology to a wide variety of environmental conditions often through the control of transcription. One of the main transcription factors involved in controlling expression of the Rhodobacter capsulatus photosystem ...

Ganglion cell complex thickness in screening of hydroxychloroquine maculopathy

Delta Journal of Ophthalmology, 2020
Background Screening of early hydroxychloroquine (HCQ) maculopathy is important to prevent permanent structural and functional retinal damage. Spectral domain optical coherence tomography (SD-OCT) ultra-high-resolution imaging and speed allows better ...

Targeting the HDAC6‐Cilium Axis Ameliorates the Pathological Changes Associated with Retinopathy of Prematurity

Advanced Science, 2022
Retinopathy of prematurity (ROP) is one of the leading causes of childhood visual impairment and blindness. However, there are still very few effective pharmacological interventions for ROP.

Docosahexaenoic acid preserves visual function by maintaining correct disc morphology in retinal photoreceptor cells

Journal of Biological Chemistry, 2017
Docosahexaenoic acid (DHA) has essential roles in photoreceptor cells in the retina and is therefore crucial to healthy vision. Although the influence of dietary DHA on visual acuity is well known and the retina has an abundance of DHA-containing ...

Cholesterol homeostasis in the vertebrate retina: biology and pathobiology

Journal of Lipid Research, 2021
: Cholesterol is a quantitatively and biologically significant constituent of all mammalian cell membrane, including those that comprise the retina. Retinal cholesterol homeostasis entails the interplay between de novo synthesis, uptake, intraretinal ...

Donor and host photoreceptors engage in material transfer following transplantation of post-mitotic photoreceptor precursors

Nature Communications, 2016
Photoreceptor replacement by transplantation is proposed as a treatment for blindness. Transplantation of healthy photoreceptor precursor cells into diseased murine eyes leads to the presence of functional photoreceptors within host retinae that express ...

On dispersion in visual photoreceptors [PDF]

Vision Research, 1975
An idealized visual pigment absorbance spectrum is used together with a Kramers-Kronig dispersion relation to calculate the contribution of the visual pigment to the refractive index of the fly photoreceptor. It appears that an absorption coefficient of 0.010 µm-1 results in a refractive index variation of less than 5 × 10-4.

Loss of Motor Protein MYO1C Causes Rhodopsin Mislocalization and Results in Impaired Visual Function

Cells, 2021
Unconventional myosins, linked to deafness, are also proposed to play a role in retinal cell physiology. However, their direct role in photoreceptor function remains unclear.
