Orexinergic Input to Dopaminergic Neurons of the Human Ventral Tegmental Area [PDF]
, 2013 The mesolimbic reward pathway arising from dopaminergic (DA) neurons of the ventral tegmental area (VTA) has been strongly implicated in reward processing and drug abuse.

Effects of Orexin A on Thermal Behaviour: Substantial Evidences for Thermoregulatory Role of Orexin A [PDF]
OMICS Journal of Radiology, 2014 Orexin A is a hypothalamic neuropeptide produced in the dorsal and lateral hypothalamus, and orexin-producing cell have widespread anatomical projections within the central nervous system. Orexin A is involved in multiple physiological functions, including eating behavior, thermoregulation, and sleep-regulation.

Orexin A Controls Glucose Metabolism [PDF]
Journal of Diabetes & Metabolism, 2014 The orexin-A and orexin-B are a hypothalamic neuropeptides, involved in the regulation of feeding behaviour, sleep-wakefulness rhythm, and neuroendocrine homeostasis that influence the sympathetic nervous system activity, blood pressure regulation, and metabolic status, glycemic, and may contribute to increase diabetics morbidity and mortality.

Orexin A suppresses in vivo GH secretion [PDF]
European Journal of Endocrinology, 2004 BACKGROUND/AIMS: Orexins (OXs) are a newly described family of hypothalamic neuropeptides. Based on the distribution of OX neurons and their receptors in the brain, it has been postulated that they could play a role in the regulation of neuroendocrine function. GH secretion is markedly influenced by nutritional status and body weight.

Orexin-Corticotropin-Releasing Factor Receptor Heteromers in the Ventral Tegmental Area as Targets for Cocaine [PDF]
, 2015 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.

Orexin A activates retrotrapezoid neurons in mice [PDF]
Respiratory Physiology & Neurobiology, 2011 The retrotrapezoid nucleus (RTN), located at the ventral surface of the medulla oblongata, contains glutamatergic Phox2b-expressing interneurons that have central respiratory chemoreceptor properties. RTN also operates as a relay for hypothalamic pathways that regulate breathing, one of which probably originates from the orexinergic neurons (Dias et al.

Orexin-1 receptor-cannabinoid CB1 receptor heterodimerization results in both ligand-dependent and -independent coordinated alterations of receptor localization and function [PDF]
, 2006 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.

DEC2 modulates orexin expression and regulates sleep. [PDF]
, 2018 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.

Presence of orexin A and orexin 1 receptor in the buffalo prostate
Italian Journal of Animal Science, 2010 The orexins A and B are two peptides discovered initially in the rat lateral hypothalamus involved in the regulation of some body functions such as food intake, sleep/wake cycle, arterial pressure and heart rate. They interact with two receptors defined &

Evolution of Orexin Neuropeptide System: Structure and Function
Frontiers in Neuroscience, 2020 Orexins are hypothalamic neuropeptides that were initially identified in the rat brain as endogenous ligands for an (previously) orphan G-protein-coupled receptor (GPCR).
