Predicting peak spectral sensitivities of vertebrate cone visual pigments using atomistic molecular simulations. [PDF]

open access: yesPLoS Computational Biology, 2018
Vision is the dominant sensory modality in many organisms for foraging, predator avoidance, and social behaviors including mate selection. Vertebrate visual perception is initiated when light strikes rod and cone photoreceptors within the neural retina ...

Activation of mislocalized opsin kills rod cells: A novel mechanism for rod cell death in retinal disease [PDF]

open access: yesProceedings of the National Academy of Sciences, 2002
Rod photoreceptors are highly compartmentalized sensory neurons that maintain strict ultrastructural and molecular polarity. Structural subdivisions include the outer segment, inner segment, cell body, and synaptic terminal. The visual pigment rhodopsin is found predominantly in membranes of the rod cell outer segment but becomes mislocalized ...

The Effect of Cone Opsin Mutations on Retinal Structure and the Integrity of the Photoreceptor Mosaic [PDF]

open access: yes, 2012
Purpose. To evaluate retinal structure and photoreceptor mosaic integrity in subjects with OPN1LW and OPN1MW mutations. Methods. Eleven subjects were recruited, eight of whom have been previously described.

Dampening Spontaneous Activity Improves the Light Sensitivity and Spatial Acuity of Optogenetic Retinal Prosthetic Responses [PDF]

open access: yes, 2016
Retinitis pigmentosa is a progressive retinal dystrophy that causes irreversible visual impairment and blindness. Retinal prostheses currently represent the only clinically available vision-restoring treatment, but the quality of vision returned remains ...

Molecular Aspects of Eye Evolution and Development: From the Origin of Retinal Cells to the Future of Regenerative Medicine [PDF]

open access: yes, 2013
A central issue of evolutionary developmental biology is how the eye is diverged morphologically and functionally. However, the unifying mechanisms or schemes that govern eye diversification remain unsolved.

Mutation in the intracellular chloride channel CLCC1 associated with autosomal recessive retinitis pigmentosa. [PDF]

open access: yesPLoS Genetics, 2018
We identified a homozygous missense alteration (c.75C>A, p.D25E) in CLCC1, encoding a presumptive intracellular chloride channel highly expressed in the retina, associated with autosomal recessive retinitis pigmentosa (arRP) in eight consanguineous ...

Genetic Dissection of Dual Roles for the Transcription Factor six7 in Photoreceptor Development and Patterning in Zebrafish. [PDF]

open access: yesPLoS Genetics, 2016
The visual system of a particular species is highly adapted to convey detailed ecological and behavioral information essential for survival. The consequences of structural mutations of opsins upon spectral sensitivity and environmental adaptation have ...

Visual pigments, ocular filters and the evolution of snake vision [PDF]

open access: yes, 2016
Much of what is known about the molecular evolution of vertebrate vision comes from studies of mammals, birds and fish. Reptiles (especially snakes) have barely been sampled in previous studies despite their exceptional diversity of retinal photoreceptor

Spatiotemporal control of genome engineering in cone photoreceptors

open access: yesCell & Bioscience, 2023
Background Cones are essential for color recognition, high resolution, and central vision; therefore cone death causes blindness. Understanding the pathophysiology of each cell type in the retina is key to developing therapies for retinal diseases ...

Morphological Plasticity of the Retina of Viperidae Snakes Is Associated With Ontogenetic Changes in Ecology and Behavior

open access: yesFrontiers in Neuroanatomy, 2022
Snakes of the Viperidae family have retinas adapted to low light conditions, with high packaging of rod-photoreceptors containing the rhodopsin photopigment (RH1), and three types of cone-photoreceptors, large single and double cones with long-wavelength
