Ageing‐related modification of sleep and breathing in orexin‐knockout narcoleptic mice

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Narcolepsy type‐1 (NT1) is a lifelong sleep disease, characterised by impairment of the orexinergic system, with a typical onset during adolescence and young adulthood. Since the wake–sleep cycle physiologically changes with ageing, this study aims to compare sleep patterns between orexin‐knockout (KO) and wild type (WT) control mice at ...

Orexin-1 receptor blockade dysregulates REM sleep in the presence of orexin-2 receptor antagonism [PDF]

open access: yesFrontiers in Neuroscience, 2014
In accordance with the prominent role of orexins in the maintenance of wakefulness via activation of orexin-1 (OX1R) and orexin-2 (OX2R) receptors, various dual OX1/2R antagonists have been shown to promote sleep in animals and humans. While selective blockade of OX2R seems to be sufficient to initiate and prolong sleep, the beneficial effect of ...

Orexin-A exerts equivocal role in atherosclerosis process depending on the duration of exposure : in vitro study [PDF]

open access: yes, 2019
Orexin-A is a peptide hormone that plays a crucial role in feeding regulation and energy homeostasis. Diurnal intermittent fasting (DIF) has been found to increase orexin-A plasma levels during fasting hours, while Ramadan fasting which resembles DIF ...

Parasomnias and sleep‐related movement disorders induced by drugs in the adult population: a review about iatrogenic medication effects

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Parasomnias and sleep‐related movement disorders (SRMD) are major causes of sleep disorders and may be drug induced. The objective of this study was to conduct a systematic review of the literature to examine the association between drug use and the occurrence of parasomnias and SRMD.

Respiratory safety of lemborexant in adult and elderly subjects with moderate‐to‐severe chronic obstructive pulmonary disease

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Lemborexant 10 mg, a dual orexin‐receptor antagonist (DORA), did not elicit respiratory depressant effects, as measured by peripheral oxygen saturation (SpO2) or apnea–hypopnea index (AHI), in subjects with moderate‐to‐severe chronic obstructive pulmonary disease (COPD).

A Meta‐Analysis of the Effects of Acute Sleep Deprivation on the Cortical Transcriptome in Rodent Models

open access: yesJournal of Sleep Research, EarlyView.
How does sleep deprivation affect the brain? We performed a meta‐analysis of publicly available transcriptional profiling datasets characterising the effects of sleep deprivation on cortical gene expression (n = 293 mice, 16,290 genes) and validated our results in an independent sample (n = 222 mice).

Mechanisms responsible for the effect of median nerve electrical stimulation on traumatic brain injury-induced coma: orexin-A-mediated N-methyl-D-aspartate receptor subunit NR1 upregulation

open access: yesNeural Regeneration Research, 2016
Electrical stimulation of the median nerve is a noninvasive technique that facilitates awakening from coma. In rats with traumatic brain injury-induced coma, median nerve stimulation markedly enhances prefrontal cortex expression of orexin-A and its ...

Overnight Dynamics of Ventricular Cerebrospinal Fluid Amyloid‐Beta, Lactate and Hypocretin in Patients With Hydrocephalus: A Pilot Study

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT This pilot observational study evaluated whether frequent overnight sampling of ventricular cerebrospinal fluid could clarify how sleep, hypocretin and lactate relate to amyloid‐β42 dynamics in adults with hydrocephalus. Seven participants underwent hourly ventricular cerebrospinal fluid sampling from early evening to late morning during ...
