Orexin-A and B were identified as endogenous ligands for the orexin-1 (HCRT1) and orexin-2 (HCRT2) G-protein coupled receptors (Sakurai et al, 1998). These peptides are identical to two hypothalamic peptides that share a high degree of homology with secretin, designated hypocretin-1 and hypocretin-2 (De Lecea et al, 1998). ICV administration of orexin-A and B stimulated food intake in rats. Additionally, prepro-orexin mRNA levels were upregulated in fasting rats. Recent reports suggest a role in the sleep-wake cycle.
