orexincontaining
Orexincontaining refers to substances or cells that contain orexin, also known as hypocretin. Orexin is a neuropeptide produced by a small group of neurons located in the hypothalamus of the brain. These neurons are characterized by their expression of the orexin peptides, orexin-A and orexin-B, and their receptors, OX1R and OX2R. The orexin system plays a crucial role in regulating various physiological processes, most notably wakefulness and arousal.
The orexincontaining neurons project widely throughout the brain, innervating areas involved in sleep-wake cycles, appetite, reward,
Beyond its role in sleep, orexin also influences feeding behavior by promoting food seeking and consumption.
