The photoreceptor mosaic [PDF]

Eye, 1998
The organisation of the human photoreceptor mosaic reflects evolutionary strategies for optimising visual information under a wide range of stimulus conditions: (1) The rod population dominates (max. 170,000/mm2 at c. 30 degrees sup.) except for the central 2 degrees and along the ora serrata.

Human Tau Expression Does Not Induce Mouse Retina Neurodegeneration, Suggesting Differential Toxicity of Tau in Brain vs. Retinal Neurons

Frontiers in Molecular Neuroscience, 2018
The implication of the microtubule-associated protein (MAP) Tau in the ocular manifestations of Alzheimer’s disease (AD) is elusive due to the lack of relevant animal model.

Phosphoinositides and Photoreceptors [PDF]

Molecular Neurobiology, 2011
The importance of phosphoinositides (phosphorylated phosphatidyl inositol derivatives, PIs) for normal cellular function cannot be overstated. Although they represent a small fraction of the total phospholipid within the cell, they are essential regulators of many cellular functions.

Case Report: Solar retinopathy following exposure to reflected sunlight

Journal of Ophthalmology, 2019
Background: Radiation damage to the eye is most commonly caused by sunlight. Solar retinopathy is a form of retinal damage that occurs after exposure to solar radiation, with the most common symptoms being reduced vision and central scotoma.

Morphology and connectivity of retinal horizontal cells in two avian species

Frontiers in Cellular Neuroscience
In the outer vertebrate retina, the visual signal is separated into intensity and wavelength information. In birds, seven types of photoreceptors (one rod, four single cones, and two members of the double cone) mediate signals to >20 types of second ...

Calcium-sensor proteins but not bicarbonate ion activate retinal photoreceptor membrane guanylyl cyclase in photoreceptors

Frontiers in Molecular Neuroscience
Retinal membrane guanylyl cyclase (RetGC), regulated by guanylyl cyclase activating proteins (GCAPs) via negative calcium-feedback, is one of the most critically important enzymes in vertebrate rod and cone physiology, enabling their sensitivity to light.

Photomorphogenesis and Photoreceptors

, 2016
Plants use light as their main source of energy and to gather information about their surroundings. The light environment is monitored through an extensive set of photoreceptors and largely dictates plant development through induction of processes such as germination and flowering, entrainment of the circadian clock and photomorphogenic responses ...

Comprehensive study of SNAREs involved in the post-Golgi transport in Drosophila photoreceptors

Frontiers in Cell and Developmental Biology
Polarized transport is essential for the construction of multiple plasma membrane domains within cells. Drosophila photoreceptors serve as excellent model systems for studying the mechanisms of polarized transport.

Morphological characterization and topographic analysis of multiple photoreceptor types in the retinae of mesopelagic hatchetfishes with tubular eyes

Frontiers in Ecology and Evolution, 2016
Marine hatchetfishes, Argyropelecus spp., are one of the 14 genera of mesopelagic teleosts, which possess tubular eyes. The tubular eyes are positioned dorsally on the head and consist of a main retina, which subtends a large dorsal binocular field, and ...
