Relation between orexin A and epileptic seizures

Epilepsy Research, 2022
One of the unknown mechanisms in epilepsy pathogenesis is the involvement of the hypothalamic neuropeptide orexin. Although the relationship between orexin and sleep has been revealed, its effect in epilepsy has not been fully clarified. In this study, we aimed to show the relationship between orexin A and the seizures that occur during sleep and ...

Radioimmunoassay for orexin A

Life Sciences, 2000
A radioimmunoassay for orexin A has been developed. Anti-orexin A antiserum was raised in New Zealand white rabbits immunized with a conjugate of synthetic orexin A with bovine serum albumin. This antibody did not crossreact with orexin B, hypothalamic hormones, pituitary hormones, neuropeptides or gut hormones.

Orexin A in swine corpus luteum

Domestic Animal Endocrinology, 2018
Orexin A (OXA) is a hypothalamic neuropeptide which acts on 2 known G-protein-coupled receptors. It has been demonstrated that OXA is a central molecular link between food intake and reproduction. More recently, its peripheral role has been investigated, and we demonstrated its involvement in regulating ovarian follicle function.

Orexin A in adolescents with anxiety disorders

International Journal of Psychiatry in Clinical Practice, 2020
Objectives: The relationships between orexins and stress-related conditions have been well documented in animal studies. However, human studies confirming this relationship are limited. The aim of this study was to investigate the association between orexin-A and anxiety disorders in adolescents.

Immunoreactive orexin-A in human plasma

Peptides, 2001
Orexin-A and orexin-B are newly discovered neuropeptides which are implicated in feeding behavior and arousal state. We studied immunoreactive(IR)-orexin-A concentrations in human plasma by radioimmunoassay. IR-orexin-A concentrations in plasma obtained from 17 healthy subjects in the morning were 1.94 +/- 0.24 pmol/liter (mean +/- SEM).

Orexin: a gatekeeper of addiction

Nature Medicine, 2006
The neurotransmitter orexin regulates motivated behaviors such as arousal and feeding—and is now implicated in behaviors associated with addiction in rats. The release of orexin onto dopamine cells enables cocaine to induce the neuronal changes that lead to addiction-like behavior.
