Generation of the melatonin endocrine message in mammals: a review of the complex regulation of melatonin synthesis by norepinephrine, peptides, and other pineal …

V Simonneaux, C Ribelayga - Pharmacological reviews, 2003 - ASPET
Melatonin, the major hormone produced by the pineal gland, displays characteristic daily
and seasonal patterns of secretion. These robust and predictable rhythms in circulating …

[HTML][HTML] The circadian clock in the retina controls rod-cone coupling

C Ribelayga, Y Cao, SC Mangel - Neuron, 2008 - cell.com
Although rod and cone photoreceptor cells in the vertebrate retina are anatomically connected
or coupled by gap junctions, a type of electrical synapse, rod-cone electrical coupling is …

Adenosine and dopamine receptors coregulate photoreceptor coupling via gap junction phosphorylation in mouse retina

…, MR Blackburn, SW Wang, CP Ribelayga… - Journal of …, 2013 - Soc Neuroscience
Gap junctions in retinal photoreceptors suppress voltage noise and facilitate input of rod
signals into the cone pathway during mesopic vision. These synapses are highly plastic and …

A circadian clock in the fish retina regulates dopamine release via activation of melatonin receptors

C Ribelayga, Y Wang, SC Mangel - The Journal of physiology, 2004 - Wiley Online Library
Although many biochemical, morphological and physiological processes in the vertebrate
retina are controlled by a circadian (24 h) clock, the location of the clock and how the clock …

[HTML][HTML] Heterogeneous expression of the core circadian clock proteins among neuronal cell types in mouse retina

X Liu, Z Zhang, CP Ribelayga - PloS one, 2012 - journals.plos.org
Circadian rhythms in metabolism, physiology, and behavior originate from cell-autonomous
circadian clocks located in many organs and structures throughout the body and that share a …

A circadian clock and light/dark adaptation differentially regulate adenosine in the mammalian retina

C Ribelayga, SC Mangel - Journal of Neuroscience, 2005 - Soc Neuroscience
Although the purine adenosine acts as an extracellular neuromodulator in the mammalian
CNS in both normal and pathological conditions and regulates sleep, the regulation of …

T-box transcription regulator Tbr2 is essential for the formation and maintenance of Opn4/melanopsin-expressing intrinsically photosensitive retinal ganglion cells

…, S Panda, S Hattar, CP Ribelayga… - Journal of …, 2014 - Soc Neuroscience
Opsin 4 (Opn4)/melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs)
play a major role in non-image-forming visual system. Although advances have been …

[HTML][HTML] Ocular clocks: adapting mechanisms for eye functions and health

…, D Hicks, SN Peirson, CP Ribelayga… - … & visual science, 2018 - tvst.arvojournals.org
Vision is a highly rhythmic function adapted to the extensive changes in light intensity
occurring over the 24-hour day. This adaptation relies on rhythms in cellular and molecular …

HIOMT drives the photoperiodic changes in the amplitude of the melatonin peak of the Siberian hamster

C Ribelayga, P Pévet… - American Journal of …, 2000 - journals.physiology.org
In the pineal, melatonin (Mel) is synthesized from serotonin by arylalkylamine-N-acetyltransferase
(AA-NAT) and hydroxyindole-O-methyltransferase (HIOMT). Although it is clear that AA…
