Bleached pigment activates transduction in salamander cones. [PDF]
, 1995 We have used suction electrode recording together with rapid steps into 0.5 mM IBMX solution to investigate changes in guanylyl cyclase velocity produced by pigment bleaching in isolated cones of the salamander Ambystoma tigrinum.

Science, 2019 Evolution![Figure][1] Noctilionoid bats, including the fishing bat shown, have complex mechanisms for eye pigment evolution. PHOTO: CHRISTIAN ZIEGLER/MINDEN PICTURES Opsin genes encode photoreceptor proteins that enable perception of dim light by rod cells and color by cone cells in the eye.

Effect of knocking down the insulin receptor on mouse rod responses. [PDF]
, 2015 Previous experiments have shown that the insulin receptor (IR) is expressed in mammalian rods and contributes to the protection of photoreceptors during bright-light exposure.

eLife, 2018 Ciliary and rhabdomeric photoreceptor cells represent two main lines of photoreceptor-cell evolution in animals. The two cell types coexist in some animals, however how these cells functionally integrate is unknown.

Exploring adult hippocampal neurogenesis using optogenetics [PDF]
, 2018 In the 1980s, it was widely accepted that new neurons are continuously generated in the dentate gyrus of the mammalian hippocampus. Since its acceptance, researchers have employed various techniques and behavioral paradigms to study the proliferation ...

Photoreceptor Outer Segment-like Structures in Long-Term 3D Retinas from Human Pluripotent Stem Cells. [PDF]
, 2017 The retinal degenerative diseases, which together constitute a leading cause of hereditary blindness worldwide, are largely untreatable. Development of reliable methods to culture complex retinal tissues from human pluripotent stem cells (hPSCs) could ...

Optogenetics: Background, Methodological Advances and Potential Applications for Cardiovascular Research and Medicine [PDF]
, 2020 Optogenetics is an elegant approach of precisely controlling and monitoring the biological functions of a cell, group of cells, tissues, or organs with high temporal and spatial resolution by using optical system and genetic engineering technologies. The

Opsin Expression in Human Epidermal Skin [PDF]
Photochemistry and Photobiology, 2014 AbstractHuman skin is constantly exposed to solar light containing visible and ultraviolet radiation (UVR), a powerful skin carcinogen. UVR elicits cellular responses in epidermal cells via several mechanisms: direct absorption of short‐wavelength UVR photons by DNA, oxidative damage caused by long‐wavelength UVR, and, as we recently demonstrated, via ...

Rapid adaptive evolution of colour vision in the threespine stickleback radiation. [PDF]
, 2016 Vision is a sensory modality of fundamental importance for many animals, aiding in foraging, detection of predators and mate choice. Adaptation to local ambient light conditions is thought to be commonplace, and a match between spectral sensitivity and ...

Exposure to the complement C5b-9 complex sensitizes 661W photoreceptor cells to both apoptosis and necroptosis. [PDF]
, 2015 The loss of photoreceptors is the defining characteristic of many retinal degenerative diseases, but the mechanisms that regulate photoreceptor cell death are not fully understood.
