Melatonin treatment affects leptin and nesfatin-1 levels but not orexin-a levels in rem sleep deprived rats [PDF]
Kafkas Universitesi Veteriner Fakültesi Dergisi, 2023 Sleep contributes to the energy balance of body. This study aims to investigate how rapid eye movement (REM) sleep deprivation (SD) or recovery sleep affects rat weight and the serum levels of Nesfatin-1, Orexin-A, and Leptin; additionally, seeks to ...

GABAergic neurons in the nucleus accumbens regulate hedonic food intake via orexin-a expression in the lateral hypothalamus [PDF]
Iranian Journal of Basic Medical Sciences, 2021 Objective(s): To investigate the regulatory effects of the nucleus accumbens (NAcSh)-lateral hypothalamus (LHA) GABAergic neural pathway on palatable food (PF) intake via orexin-A expression in diet-induced obesity (DIO) rats.

The Role of Orexin-A in Water Intake in Water-deprived Rats
The Journal of Qazvin University of Medical Sciences, 2022 Background: The lateral hypothalamus (LH), which produces orexin, is vital for body solution homeostasis. Lateral hypothalamus (LH) lesion causes adipsia and its stimulation increases water intake.

Involvement of the Orexinergic System in Feeding
Applied Sciences, 2021 To know the processes involved in feeding, the dysregulation of hypothalamic neuropeptides promoting anorexigenic/orexigenic mechanisms must be investigated. Many neuropeptides are involved in this behavior and in overweight/obesity.

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.

Neurobiology of the Orexin System and Its Potential Role in the Regulation of Hedonic Tone
Brain Sciences, 2022 Orexin peptides comprise two neuropeptides, orexin A and orexin B, that bind two G-protein coupled receptors (GPCRs), orexin receptor 1 (OXR1) and orexin receptor 2 (OXR2).

Activity of putative orexin neurons during cataplexy
Molecular Brain, 2022 It is unclear why orexin-deficient animals, but not wild-type mice, show cataplexy. The current hypothesis predicts simultaneous excitation of cataplexy-inhibiting orexin neurons and cataplexy-inducing amygdala neurons.
