The orexigenic system was discovered in 1998. It consists of two neuropeptides, Orexin A and Orexin B. Researchers have focused more on Orexin A, since its intracerebroventricular injection into the lateral ventricle of the rat's brain causes an increase

Stress, stress systems, and Alzheimer's disease
Abstract Stress is increasingly recognized as an important, modifiable factor for Alzheimer's disease (AD), yet its roles in initiation, progression, and outcomes remain incompletely elucidated. Epidemiologic studies link chronic stress, early‐life adversity, and trauma to increased AD risk, while experimental models have uncovered mechanisms by which ...

The role of orexin A in the pathogenesis of ischaemic stroke at high altitude
Orexin offers protection against cerebral ischaemia–reperfusion injury, with high altitude playing a key role in modulating its expression. This study aimed to investigate the effect of high altitude on orexin expression and its pathophysiological ...

Orexin System: The Key for a Healthy Life
The orexin-A/hypocretin-1 and orexin-B/hypocretin-2 are neuropeptides synthesized by a cluster of neurons in the lateral hypothalamus and perifornical area. Orexin neurons receive a variety of signals related to environmental, physiological and emotional
