Dual-Cell Patch-Clamp Recording Revealed a Mechanism for a Ribbon Synapse to Process Both Digital and Analog Inputs and Outputs

Frontiers in Cellular Neuroscience, 2021
A chemical synapse is either an action potential (AP) synapse or a graded potential (GP) synapse but not both. This study investigated how signals passed the glutamatergic synapse between the rod photoreceptor and its postsynaptic hyperpolarizing bipolar

Retinal cone photoreceptors of the deer mouse Peromyscus maniculatus : development, topography, opsin expression and spectral tuning [PDF]

, 2013
A quantitative analysis of photoreceptor properties was performed in the retina of the nocturnal deer mouse, Peromyscus maniculatus, using pigmented (wildtype) and albino animals.

Mouse rods signal through gap junctions with cones

eLife, 2014
Rod and cone photoreceptors are coupled by gap junctions (GJs), relatively large channels able to mediate both electrical and molecular communication. Despite their critical location in our visual system and evidence that they are dynamically gated for ...

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.

Adult limbal neurosphere cells: a potential autologous cell resource for retinal cell generation [PDF]

, 2014
The Corneal limbus is a readily accessible region at the front of the eye, separating the cornea and sclera. Neural colonies (neurospheres) can be generated from adult corneal limbus in vitro.

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 ...

Iroquois complex genes induce co-expression of rhodopsins in Drosophila. [PDF]

, 2008
The Drosophila eye is a mosaic that results from the stochastic distribution of two ommatidial subtypes. Pale and yellow ommatidia can be distinguished by the expression of distinct rhodopsins and other pigments in their inner photoreceptors (R7 and R8),

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.
