Multiple signaling pathways of orexin receptors. [PDF]

open access: yesSpringerplus, 2015
Orexin/hypocretin peptides are central for the regulation of the sleep/arousal states, and have, in addition, a role in the regulation of e.g. metabolism, addiction, stress response and pain gating. Orexin responses are mediated by G-protein-coupled OX1 and OX2 orexin receptors. Orexin signaling (in different cell types) is very versatile, ranging from

Research progress of orexin on the regulation of cardiovascular activities [PDF]

open access: yesJichu yixue yu linchuang, 2023
Orexin(OX) is a neuropeptide mainly released by the hypothalamus. In the central nervous system, orexin neurons form extensive connections with other neuronal nuclei and participate in energy metabolism, sleep cycle and cardiovascular activity regulation.

The orexin system in the enteric nervous system of the bottlenose dolphin (Tursiops truncatus). [PDF]

open access: yesPLoS ONE, 2014
This study provides a general approach to the presence and possible role of orexins and their receptors in the gut (three gastric chambers and intestine) of confined environment bottlenose dolphin.

Orexins and Their Receptors in the Human Retina [PDF]

open access: yesPathobiology, 2004
<i>Objectives:</i> Orexins A and B are neuropeptides involved in the regulation of feeding behavior, energy homeostasis and arousal. In the human retina, however, immunohistochemical localization of orexins and their receptors, OX-R1 and OX-R2, has not been ascertained.

Age-dependent down-regulation of orexin receptors in trigeminal nucleus caudalis correlated with attenuation of orexinergic analgesia in rats

open access: yesExperimental Gerontology, 2023
Aging is related to a variety of physiological organ changes, including central and peripheral nervous systems. It has been reported that the orexin signaling has a potential analgesic effect in different models of pain, especially inflammatory pulpal ...

Impact of Orexin-A Treatment on Food Intake, Energy Metabolism and Body Weight in Mice. [PDF]

open access: yesPLoS ONE, 2017
Orexin-A and -B are hypothalamic neuropeptides of 33 and 28-amino acids, which regulate many homeostatic systems including sleep/wakefulness states, energy balance, energy homeostasis, reward seeking and drug addiction.

Orexin Directly Excites Orexin Neurons through Orexin 2 Receptor [PDF]

open access: yesThe Journal of Neuroscience, 2010
Orexin neurons (hypocretin neurons) have a critical role in the regulation of sleep/wakefulness, especially in the maintenance of arousal. Here, we revealed that orexin neurons are directly and indirectly activated by orexin via the orexin 2 receptor (OX2R).

In vivo photocontrol of orexin receptors with a nanomolar light-regulated analogue of orexin-B

open access: yes, 2023
Orexinergic neurons are critically involved in regulating arousal, wakefulness, and appetite. Their dysfunction has been associated with sleeping disorders, and non-peptide drugs are currently being developed to treat insomnia and narcolepsy.

Tumor cell apoptosis mediated by the orexins

open access: yesМедицинская иммунология, 2021
Orexins A and B are neuropeptides synthesized by a population of lateral hypothalamic neurons. Orexin’s physiological function consists mainly in regulating the sleep-wake cycle, eating behavior, and energy homeostasis. Axons of orexin-containing neurons
