Acetylcholine Depolarizes Barnacle Photoreceptors [PDF]

Journal of Experimental Biology, 1985
ABSTRACT A variety of vertebrate and invertebrate sensory cells are known to be sensitive to acetylcholine (ACh), although the purpose of ACh receptors on these cells is not understood. Acetylcholine elicits action potentials from the sensory cell of the crayfish stretch receptor organ, which receives inhibitory but not excitatory ...

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.

Emerging Molecular Links Between Plant Photomorphogenesis and Virus Resistance

Frontiers in Plant Science, 2020
Photomorphogenesis refers to photoreceptor-mediated morphological changes in plant development that are triggered by light. Multiple photoreceptors and transcription factors (TFs) are involved in the molecular regulation of photomorphogenesis.

The Retinal Pigment Epithelium: a Convenient Source of New Photoreceptor cells?

Journal of Ophthalmic & Vision Research, 2014
Recent success in restoring visual function through photoreceptor replacement in mouse models of photoreceptor degeneration intensifies the need to generate or regenerate photoreceptor cells for the ultimate goal of using cell replacement therapy for ...

EF hand-mediated Ca2+- signalling in photoreceptor synaptic terminals

Frontiers in Molecular Neuroscience, 2012
Photoreceptors, the light-sensitive receptor neurons of the retina, receive and transmit a plethora of visual informations from the surrounding world. Photoreceptors capture light and convert this energy into electrical signals that are conveyed to the ...

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.

Melanopsin and Cone Photoreceptor Inputs to the Afferent Pupil Light Response

Frontiers in Neurology, 2019
Background: Retinal photoreceptors provide the main stage in the mammalian eye for regulating the retinal illumination through changes in pupil diameter, with a small population of melanopsin-expressing intrinsically photosensitive retinal ganglion cells

NAMPT-Mediated NAD+ Biosynthesis Is Essential for Vision In Mice

Cell Reports, 2016
Photoreceptor death is the endpoint of many blinding diseases. Identifying unifying pathogenic mechanisms in these diseases may offer global approaches for facilitating photoreceptor survival.

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 ...
