Orexin neurons receive glycinergic innervations. [PDF]

PLoS ONE, 2011
Glycine, a nonessential amino-acid that acts as an inhibitory neurotransmitter in the central nervous system, is currently used as a dietary supplement to improve the quality of sleep, but its mechanism of action is poorly understood.

The orexin story and orexin receptor antagonists for the treatment of insomnia

Journal of Sleep Research, 2023
SummaryInsomnia is present in up to one third of the adult population worldwide, and it can present independently or with other medical conditions such as mental, metabolic, or cardiovascular diseases, which highlights the importance of treating this multifaceted disorder. Insomnia is associated with an abnormal state of hyperarousal (increased somatic,

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 ...

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.

Narcolepsy with resolution of cataplexy and persisting orexin deficiency.

, 2020
None Narcolepsy type 1 is a debilitating chronic neurological disorder, whose main symptoms of excessive daytime sleepiness and cataplexy may partially improve with time, but typically do not fully resolve.

Profiling the sleep architecture of ageing adults using a seven‐state continuous‐time Markov model

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep is a complex biological process regulated by networks of neurons and environmental factors. As one falls asleep, neurotransmitters from sleep–wake regulating neurones work in synergy to control the switching of different sleep states throughout the night. As sleep disorders or underlying neuropathology can manifest as irregular switching,

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).

The orexin story, sleep and sleep disturbances

, 2022
The orexins, also known as hypocretins, are two neuropeptides (orexin A and B or hypocretin 1 and 2) produced by a few thousand neurons located in the lateral hypothalamus that were independently discovered by two research groups in 1998.

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 ...
