WitrynaAbstract. The hypocretins/orexins are two excitatory neuropeptides, alternately called HCRT1 or orexin-A and HCRT2 or orexin-B, that are the endogenous ligands for two … WitrynaThe loss of orexin neurons in humans leads to the disease narcolepsy, characterized by daytime sleepiness and cataplexy. Recent data suggest that orexin is also involved in emotional processing. The goal of the present study was to evaluate fear and safety learning as well as unconditioned fear (anxiety) in orexin-deficient animals.
WitrynaOur previous studies showed that the expression of orexin was decreased in mice carrying null‑mutations of the transcription factor early B‑cell factor 2 (ebf2) and that the promoter region of the prepro‑orexin (Hcrt) gene contained two putative ebf‑binding sites, termed olf‑1 sites. ...
