Frontiers in NeuroscienceDNA aptamers can bind specifically to biomolecules to modify their function, potentially making them ideal oligonucleotide therapeutics. Herein, we screened for DNA aptamer of melanopsin (OPN4), a blue-light photopigment in the retina, which plays a key ...

Firing and Receptive Field Properties of Melanopsin Retinal Ganglion Cells
, 2010 Retinal ganglion cells that express the photopigment melanopsin (MGCs) are sparsely present in the retina. In rodents, they comprise 1-3% of the total number of retinal ganglion cells.

The diverse roles of inhibition in identified neural circuits [PDF]
, 2010 Inhibitory interneurons represent a diverse population of cell types in the central nervous system, whose general role is to suppress activity of target neurons.

PLoS ONE, 2016 Melanopsin expressing intrinsically photosensitive Retinal Ganglion Cells (ipRGCs) entirely control the post-illumination pupil response (PIPR) from 6 s post-stimulus to the plateau during redilation after light offset.

Blue light activates pulvinar nuclei in longstanding idiopathic photophobia: A case report
NeuroImage: Clinical, 2019 Numerous pathologies can contribute to photophobia. When considering light transduction alone, photophobia may be triggered through melanopsin pathways (non-image forming), rod and cone pathways (image-forming), or some combination of the two.

Melanopsin in the human and chicken choroid
Experimental Eye ResearchThe choroid embedded in between retina and sclera is essential for retinal photoreceptor nourishment, but is also a source of growth factors in the process of emmetropization that converts retinal visual signals into scleral growth signals. Still, the exact control mechanisms behind those functions are enigmatic while circadian rhythms are involved ...

Immunohistochemical evidence of a melanopsin cone in human retina.
, 2006 PURPOSE: Melanopsin, expressed in a subset of intrinsically photosensitive ganglion cells that project to the suprachiasmatic nucleus (SCN), is involved in the photic entrainment of circadian rhythms and other non-image-forming functions (pupil light ...

Melanopsin phototransduction is repurposed by ipRGC subtypes to shape the function of distinct visual circuits [PDF]
, 2018 : Melanopsin is expressed in distinct types of intrinsically photosensitive retinal ganglion cells (ipRGCs), which drive behaviors from circadian photoentrainment to contrast detection. A major unanswered question is how the same photopigment, melanopsin,

Melanopsin-Driven Pupil Response and Light Exposure in Non-seasonal Major Depressive Disorder
Frontiers in Neurology, 2018 Background: Melanopsin-expressing intrinsically photosensitive Retinal Ganglion Cells (ipRGCs) signal non-imaging forming effects of environmental light for circadian phoentrainment, the pupil light reflex, and mood regulation.

Slow vision:Measuring melanopsin-mediated light effects in animal models
, 2022 Mammalian retinas contain three specialized photoreceptors: the rods and cones in the outer retina, whose primary function is to support visual perception in dim and bright environments, respectively, and a small subset of retinal ganglion cells ...
