Orexin-A exerts neuroprotective effect in experimental intracerebral hemorrhage by suppressing autophagy via OXR1-mediated ERK/mTOR signaling pathway

open access: yesFrontiers in Cellular Neuroscience, 2022
BackgroundOrexin-A (OXA) is a polypeptide produced in the hypothalamus, which binds to specific receptors and exerts multiple physiological effects. Autophagy plays a vital role in early brain injury (EBI) after intracerebral hemorrhage (ICH).

The role of orexin A in pathophysiological mechanisms of sleep disorder in postmenopausal women

open access: yesГинекология, 2020
Aim. To conduct a comparative analysis of serum orexin A levels in women of different age periods with and without sleep disorder and vasomotor symptoms. To evaluate the dynamics of orexin A levels under menopausal hormone therapy.

Neurobiology of the Orexin System and Its Potential Role in the Regulation of Hedonic Tone

open access: yesBrain Sciences, 2022
Orexin peptides comprise two neuropeptides, orexin A and orexin B, that bind two G-protein coupled receptors (GPCRs), orexin receptor 1 (OXR1) and orexin receptor 2 (OXR2).

Activity of putative orexin neurons during cataplexy

open access: yesMolecular Brain, 2022
It is unclear why orexin-deficient animals, but not wild-type mice, show cataplexy. The current hypothesis predicts simultaneous excitation of cataplexy-inhibiting orexin neurons and cataplexy-inducing amygdala neurons.

Orexin-Corticotropin-Releasing Factor Receptor Heteromers in the Ventral Tegmental Area as Targets for Cocaine [PDF]

open access: yes, 2015
Release of the neuropeptides corticotropin-releasing factor (CRF) and orexin-A in the ventral tegmental area (VTA) play an important role in stress-induced cocaine-seeking behavior.

Presence of orexin A and orexin 1 receptor in the buffalo prostate

open access: yesItalian Journal of Animal Science, 2010
The orexins A and B are two peptides discovered initially in the rat lateral hypothalamus involved in the regulation of some body functions such as food intake, sleep/wake cycle, arterial pressure and heart rate. They interact with two receptors defined &

Involvement of the Orexinergic System in Cancer: Antitumor Strategies and Future Perspectives

open access: yesApplied Sciences, 2023
Peptides promote the mitogenesis and migration of tumor cells, and cancer cells overexpress peptide receptors. The involvement of the orexinergic system in cancer is reviewed here, including thirteen cancer types (e.g., adrenocortical adenoma, breast ...

DEC2 modulates orexin expression and regulates sleep. [PDF]

open access: yes, 2018
Adequate sleep is essential for physical and mental health. We previously identified a missense mutation in the human DEC2 gene (BHLHE41) leading to the familial natural short sleep behavioral trait.

Evolution of Orexin Neuropeptide System: Structure and Function

open access: yesFrontiers in Neuroscience, 2020
Orexins are hypothalamic neuropeptides that were initially identified in the rat brain as endogenous ligands for an (previously) orphan G-protein-coupled receptor (GPCR).

Orexin-A and Orexin-B During the Postnatal Development of the Rat Brain [PDF]

open access: yesCellular and Molecular Neurobiology, 2009
Orexin-A and orexin-B are hypothalamic neuropeptides isolated from a small group of neurons in the hypothalamus, which project their axons to all major parts of the central nervous system. Despite the extensive information about orexin expression and function at different parts of the nervous system in adults, data about the development and maturation ...
