Narcolepsy and rapid eye movement sleep

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Since the first description of narcolepsy at the end of the 19th Century, great progress has been made. The disease is nowadays distinguished as narcolepsy type 1 and type 2. In the 1960s, the discovery of rapid eye movement sleep at sleep onset led to improved understanding of core sleep‐related disease symptoms of the disease (excessive ...

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

Journal 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 ...

Discovery of an orexin receptor positive potentiator [PDF]

Chemical Science, 2010
The orexin neurohormones control a variety of important physiological processes by signaling through two related G protein-coupled receptors, including appetite and feeding, wakefulness and energy homeostasis. Pharmacological manipulation of orexin signaling is an important goal.

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

Journal 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.

Design and synthesis of orexin 1 receptor-selective agonists

, 2022
Orexins are a family of neuropeptides that regulate various physiological events such as sleep/wakefulness as well as emotional and feeding behavior, and that act on two G-protein-coupled receptors, i.e., the orexin 1 (OX1R) and orexin 2 receptors (OX2R).

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

Journal 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).

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

Journal 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 ...

Physiological Roles of Orexin Receptors on Sleep/Wakefulness Regulation

, 2015
Hypothalamic neuropeptides orexin-A and orexin-B play critical roles in the regulation of sleep/wakefulness, as well as in a variety of physiological functions including emotion, reward and energy homeostasis.
