1. Intro Found out in 1998 [1, 2], the Rabbit polyclonal to A4GALT orexin (ORX: also known as hypocretin) neuropeptide system is unique due to the ORX neurons becoming exclusive to a small region of the hypothalamus that encompasses the dorsomedial/perifornical (DMH/PeF) and adjacent lateral (LH) hypothalamus. (bioinf.org)
Peptides2
Both orexin receptors exhibit a similar pharmacology - the 2 orexin peptides, orexin-A and orexin-B, bind to both receptors and, in each case, agonist binding results in an increase in intracellular calcium levels. (wikipedia.org)
Peptides and small proteins have essential physiological roles including metabolism (insulin), sleep (orexin), and stress (corticotropin-releasing hormone). (harvard.edu)
Hypocretin2
The orexin receptor (also referred to as the hypocretin receptor) is a G-protein-coupled receptor that binds the neuropeptide orexin. (wikipedia.org)
A possible link between lack of sleep (insomnia) and obesity has been traced to hypocretin/orexin cells in the hypothalamus region of the brain that are easily excited and sensitive to stress, Yale School of Medicine researchers report in the April issue of Cell Metabolism. (news-medical.net)
Receptors3
However, orexin-B shows a 5- to 10-fold selectivity for orexin receptor type 2, whilst orexin-A is equipotent at both receptors. (wikipedia.org)
The current study was carried out to investigate the mRNA expression of the prepro-orexin gene (PPO) and orexin receptors (OX1R and OX2R) in ovarian follicles during different stages of their development in the ovary of water buffalo (Bubalus bubalis) and to determine the role of orexin on oestradiol production.

Lemborexant, an orexin receptor antagonist, was approved for use in the United States in 2019. (wikipedia.org)
of two different anxiogenic/panicogenic medications (FG-7142, an inverse agonist on the benzodiazepine site from the GABAA receptor, and caffeine, a non-selective competitive adenosine receptor antagonist) elevated c-Fos induction in a particular subset of orexin neurons situated in the dorsomedial/ perifornical (DMH/PeF) however, not the lateral hypothalamus. (bioinf.org)
Pre-treating rats with an orexin 1 receptor antagonist attenuated the FG-7142-induced anxiety-like behaviors, elevated heartrate, and neuronal activation in essential anxiety pathways, including subregions from the central nucleus from the amygdala, bed NVP-AEW541 supplier nucleus from the stria terminalis, periaqueductal grey and in the rostroventrolateral medulla.

HE BIOSYNTHESIS OF mammalian neuropeptide hormones follows the principles of the prohormone theory, which begins with an mRNA translation process into a large, inactive precursor polypeptide, followed by a limited posttranslational proteolysis to release different products of processing (1).
