Age-related central regulation of orexin and NPY in the short-lived African killifish Nothobranchius furzeri [PDF]

, 2019
Orexin A (OXA) and neuropeptide Y (NPY) are two hypothalamic neuropeptides involved in the regulation of feeding behavior and food intake in all vertebrates.

Associations of Cerebrospinal Fluid Orexin‐A, Alzheimer Disease Biomarkers, and Cognitive Performance

Annals of Clinical and Translational Neurology
Objective Cerebrospinal fluid (CSF) orexin‐A has been suggested to be a biomarker of Alzheimer disease (AD). In both cognitively unimpaired healthy older adults and individuals with symptomatic AD, CSF orexin‐A is positively associated with CSF Aβ42, p ...

Comparative effects of hypnotic agents on sleep architecture and respiratory outcomes in obstructive sleep apnea: A systematic review and network meta‐analysis

Psychiatry and Clinical Neurosciences, Volume 80, Issue 5, Page 390-397, May 2026.
Aim This network meta‐analysis of randomized controlled trials (RCTs) aimed to investigate which hypnotics are associated with the most favorable sleep architecture and respiratory outcomes in adults with obstructive sleep apnea. Methods Primary outcomes included total sleep time (TST) and apnea–hypopnea index (AHI) during TST.

Recruitment of hypothalamic orexin neurons after formalin injections in adult male rats exposed to a neonatal immune challenge [PDF]

, 2015
Exposure to early life physiological stressors, such as infection, is thought to contribute to the onset of psychopathology in adulthood. In animal models, injections of the bacterial immune challenge, lipopolysaccharide (LPS), during the neonatal period

Differential roles of orexin receptors in the regulation of sleep/wakefulness

Frontiers in Endocrinology, 2013
Orexin A and orexin B are hypothalamic neuropeptides that play critical roles in the regulation of sleep/wakefulness, as well as in a variety of physiological functions such as emotion, reward, and energy homeostasis.

Effect of orexin-B-saporin-induced lesions of the lateral hypothalamus on performance on a progressive ratio schedule [PDF]

, 2012
It has been suggested that a sub-population of orexinergic neurones whose somata lie in the lateral hypothalamic area (LHA) play an important role in regulating the reinforcing value of both food and drugs.

Reactivation of hyperglycemia-induced hypocretin (HCRT) gene silencing by N-acetyl-d-mannosamine in the orexin neurons derived from human iPS cells

Epigenetics, 2017
Orexin neurons regulate critical brain activities for controlling sleep, eating, emotions, and metabolism, and impaired orexin neuron function results in several neurologic disorders.

The Effect of Porcine Orexin a on Glucose-Dependent Insulinotropic Polypeptide Plasma Concentrations in Pigs

European Journal of Inflammation, 2010
The orexigenic system was discovered in 1998. It consists of two neuropeptides, Orexin A and Orexin B. Researchers have focused more on Orexin A, since its intracerebroventricular injection into the lateral ventricle of the rat's brain causes an increase
