Impact of Human Melanopsin Gene (OPN4) Polymorphisms (I394T, P10L) on Nocturnal Melatonin and Daily Rhythms in Young Adults

open access: yesJournal of Pineal Research, Volume 78, Issue 5, September 2026.
ABSTRACT The present study investigates the impact of two missense SNPs in the human melanopsin gene OPN4 ‐I394T (rs1079610) and P10L (rs2675703)‐ on non‐image‐forming (NIF) physiological and behavioural outputs in healthy young adults under real‐world conditions.

Effects of Indirect Pupillary Light Reflex Stimulation With Colored Light on Corneal Specular Microscopy Performance in Dogs

open access: yesVeterinary Ophthalmology, Volume 29, Issue 5, September 2026.
ABSTRACT Objective To compare the effects of indirect pupillary light reflex (PLR) stimulation using differently colored lights on corneal specular microscopy performance in dogs and to determine the influence of pupil diameter. Animals Studied 20 client‐owned dogs (38 eyes) with healthy corneas.

Supraspinal Circuit Mechanisms Underlying Itch Processing

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 7, July 2026.
Peripheral pruriceptive signals ascend from the spinal cord to the brainstem, thalamus, and cortex to encode the sensory features of itch. Parallel projections to limbic and basal ganglia circuits mediate affective and motivational components, including aversion and scratching urge.

Prolonged exposure to artificial light and carcinogenesis: A systematic review of oncostatic mechanisms associated with melatonin pathways

open access: yesPhotochemistry and Photobiology, Volume 102, Issue 4, Page 780-796, July/August 2026.
Exposure to artificial light at night (ALAN), particularly at blue wavelengths, disrupts circadian rhythms by suppressing melatonin, thereby increasing cancer susceptibility. This systematic review consolidates evidence linking prolonged ALAN exposure to an elevated risk of breast and prostate tumors.

ipRGC intrinsic phototransduction persists in Gna11; Gna14 DKO mice.

open access: yes, 2014
A. Representative voltage traces for ipRGC intrinsic light responses in WT and Gna11; Gna14 DKO retinas at two 480 nm light intensities (7×1012 and 7×1013 photons/cm2/sec). Horizontal bar represents light stimulation (60 sec).

Retinal ganglion cell degeneration in glaucoma disrupts HPA axis temporal organization and dampens corticosterone production

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 4, April 2026.
Abstract Glaucoma is a chronic optic neuropathy characterized by progressive vision loss. A previous study from our group showed that glaucoma‐induced retinal degeneration disrupts photic signaling to the suprachiasmatic nucleus (SCN), altering the molecular components of the central circadian clock.

Domain of metamers exciting intrinsically photosensitive retinal ganglion cells (ipRGCs) and rods [PDF]

open access: yesJournal of the Optical Society of America A, 2012
Any stimulus can be described as composed of two components-a fundamental color stimulus that controls the three cone responses and a metameric black that has no effect on cones but can drive photoreceptors other than cones [e.g., rods and melanopsin expressing retinal ganglion cells (ipRGCs)]. The Cohen and Kappauf [Am. J. Psychol.
