Orexin, Orexin Receptor Antagonists and Central Cardiovascular Control [PDF]
Orexin makes an important contribution to the regulation of cardiovascular function. When injected centrally under anesthesia, orexin increases blood pressure, heart rate and sympathetic nerve activity.

Orexin Directly Excites Orexin Neurons through Orexin 2 Receptor [PDF]
Orexin neurons (hypocretin neurons) have a critical role in the regulation of sleep/wakefulness, especially in the maintenance of arousal. Here, we revealed that orexin neurons are directly and indirectly activated by orexin via the orexin 2 receptor (OX2R).

Orexin-A Inhibits Lipopolysaccharide-Induced Cell Migration in Cultured Mouse Astrocytes via Activation of Orexin 1 Receptor: Involvement of GABA Signaling. [PDF]
ABSTRACT It has been suggested that orexin‐A (OXA) exerts neuroprotective and anti‐inflammatory effects in the nervous system, while there is limited understanding of the role of OXA in cortical astrocytes under inflammation. This study was designed to investigate whether OXA could inhibit astrocyte migration induced by lipopolysaccharide (LPS ...

DEC2 modulates orexin expression and regulates sleep. [PDF]
Adequate sleep is essential for physical and mental health. We previously identified a missense mutation in the human DEC2 gene (BHLHE41) leading to the familial natural short sleep behavioral trait.

Orexin-Corticotropin-Releasing Factor Receptor Heteromers in the Ventral Tegmental Area as Targets for Cocaine [PDF]
Release of the neuropeptides corticotropin-releasing factor (CRF) and orexin-A in the ventral tegmental area (VTA) play an important role in stress-induced cocaine-seeking behavior.

Neurotensin co-expressed in orexin-producing neurons in the lateral hypothalamus plays an important role in regulation of sleep/wakefulness states. [PDF]
Both orexin and neurotensin are expressed in the lateral hypothalamic area (LHA) and have been implicated in the regulation of feeding, motor activity and the reward system.

Orexin Signaling: A Complex, Multifaceted Process
The orexin system comprises two G protein-coupled receptors, OX1 and OX2 receptors (OX1R and OX2R, respectively), along with two endogenous agonists cleaved from a common precursor (prepro-orexin), orexin-A (OX-A) and orexin-B (OX-B).

Orexin-1 receptor-cannabinoid CB1 receptor heterodimerization results in both ligand-dependent and -independent coordinated alterations of receptor localization and function [PDF]
Following inducible expression in HEK293 cells, the human orexin-1 receptor was targeted to the cell surface but became internalized following exposure to the peptide agonist orexin A.
