Cnidocyte discharge is regulated by light and opsin-mediated phototransduction
BMC Biology, 2012 Background Cnidocytes, the eponymous cell type of the Cnidaria, facilitate both sensory and secretory functions and are among the most complex animal cell types known.

CNS Neuroscience &Therapeutics, Volume 32, Issue 10, October 2026.Hyperglycemia induces retinal microglial activation and CTSS upregulation, disrupting microglia‐endothelial crosstalk via PAR2‐dependent MFSD2A suppression. Abnormal activation of microglia amplifies retinal inflammatory cascade, enhances transcytosis, compromises BRB integrity, and accelerates DR progression.

Phototransduction and retinal degeneration in Drosophila [PDF]
Pflügers Archiv - European Journal of Physiology, 2007 Drosophila visual transduction is the fastest known G-protein-coupled signaling cascade and has therefore served as a genetically tractable animal model for characterizing rapid responses to sensory stimulation. Mutations in over 30 genes have been identified, which affect activation, adaptation, or termination of the photoresponse.

Movement Disorders, Volume 41, Issue 10, Page 2706-2711, October 2026.Abstract Aims To conduct a case–control study to investigate melanopsin‐mediated post‐illumination pupillary response (PIPR) in patients with Parkinson's disease (PD), video‐polysomnography‐confirmed isolated/idiopathic rapid eye movement (REM) sleep behavior disorder (iRBD), and age‐matched healthy controls (HC). Methods PIPR was measured at 6 s after

Pest Management Science, Volume 82, Issue 10, Page 9592-9598, October 2026.We identified four kinds of target molecules against (‐)‐α‐thujone associating avoidance behavior in Tribolium castaneum, indicating multimodality. Abstract BACKGROUND The reciprocal evolutionary processes among phytophagous insects and host plants involve host shift in the herbivorous insects in response to defense chemicals, such as plant‐derived ...

Acta Ophthalmologica, Volume 104, Issue S293, Page S4-S35, October 2026.ENGLISH SUMMARY In developed countries, age‐related macular degeneration (AMD) is the leading cause of visual impairment in the aging population. Understanding of its pathogenesis is limited and the number of patients is predicted to continue rising. AMD is classified into two main forms: dry and neovascular AMD (dAMD and nAMD, respectively).

Frontiers in Molecular Neuroscience, 2018 Cryptochromes (CRYs) are a class of flavoproteins that sense blue light. In animals, CRYs are expressed in the eyes and in the clock neurons that control sleep/wake cycles and are implied in the generation and/or entrainment of circadian rhythmicity ...

Control of the Nucleotide Cycle in Photoreceptor Cell Extracts by Retinal Degeneration Protein 3
Frontiers in Molecular Neuroscience, 2018 Retinal degeneration protein 3 (RD3) is crucial for photoreceptor cell survival and linked to Leber Congenital Amaurosis type 12 (LCA12), a hereditary retinal disease in humans.

ROS-GC interlocked Ca2+-sensor S100B protein signaling in cone photoreceptors: Review
Frontiers in Molecular Neuroscience, 2014 Photoreceptor rod outer segment membrane guanylate cyclase (ROS-GC) is central to visual transduction; it generates cyclic GMP, the second messenger of the photon signal.
