Involvement of PLAGL1/ZAC1 in hypocretin/orexin transcription
The hypocretin/orexin neuropeptide system coordinates the regulation of various physiological processes. Our previous study reported that a reduction in the expression of pleomorphic adenoma gene-like 1 (Plagl1), which encodes a C2H2 zinc-finger ...

Temporal Course of Cerebral Autoregulation in Patients With Narcolepsy Type 1: Two Case Reports
Cerebral autoregulation is the mechanism by which constant cerebral blood flow is maintained despite changes in arterial blood pressure. In the two presented cases, cerebral autoregulation was impaired in patients with narcolepsy type 1, and both ...

Effects of Traumatic Brain Injury on the Orexin/Hypocretin System
Traumatic Brain Injuries (TBIs) are known to cause a myriad of symptoms in patients. One common symptom after injury is sleep disruptions. One neuropeptide system has been studied repeatedly as a potential cause of sleep disruptions after TBI- the orexin/

Orexin/hypocretin and dysregulated eating: Promotion of foraging behavior
At its discovery, orexin/hypocretin (OX) was hypothesized to promote food intake. Subsequently, with the identification of the participation of OX in numerous other phenomena, including arousal and drug seeking, this neuropeptide was proposed to be ...

Orexin/hypocretin peptide (orexin-A and orexin-B) signaling is believed to take place via the two G-protein-coupled receptors (GPCRs), named OX1 and OX2 orexin receptors, as described in the previous chapters. Signaling of orexin peptides has been investigated in diverse endogenously orexin receptor-expressing cells - mainly neurons but also other ...

Addiction and arousal: the hypocretin connection
The hypocretins, also known as orexins, are two neuropeptides now commonly described as critical components to maintain and regulate the stability of arousal. Several lines of evidence have raised the hypothesis that hypocretin-producing neurons are part

Regulation of zebrafish sleep and arousal states: current and prospective approaches
Every day, we shift among various states of sleep and arousal to meet the many demands of our bodies and environment. A central puzzle in neurobiology is how the brain controls these behavioral states, which are essential to an animal’s well-being and ...

A Decade of Orexin/Hypocretin and Addiction: Where Are We Now?
One decade ago, our laboratory provided the first direct evidence linking orexin/hypocretin signaling with drug seeking by showing that activation of these neurons promotes conditioned morphine-seeking behavior.
