Multifaceted Roles of Orexins: Sleep, Pain and Reward Regulations

Sun. Oct 13, 2019 10:30 AM - 12:10 PM Room 16 (Heian)

Organizer / Chair: ‌Lih-Chu CHIOU (Graduate Institute of Brain and Mind Sciences, Department of Pharmacology, College of Medicine, National Taiwan University, Taiwan), Co-chair: Hiroshi NAGASE (International Institute for Integrative Sleep Medicine, University of Tsukuba, Japan), Discussants: ‌Akihiro YAMANAKA (Research Institute of Environmental Medicine, Nagoya University, Japan), Makoto TSUDA (Department of Life Innovation, Graduate School of Pharmaceutical Sciences, Kyushu University, Japan)

Orexin A and orexin B, also named “hypocretin 1” and “hypocretin 2,” are a pair of neuropeptides derived from prepro-hypocretin. Orexin-expressing neurons are limited, mostly in the perifonical area and lateral hypothalamus, however project widely throughout the central nervous system. Orexins are found to mediate various neuro-cognitive functions, depending on the distributions of the receptors, namely OX1 and OX2 receptors. Interestingly, orexins often work hand-in-hand with other neuropeptides in the CNS to execute their regulatory roles. Complexed neuropeptide network, with orexins holding the pivotal role, were previously reported in sleep, pain and reward regulations. Pathological conditions related to these processes, including narcolepsy, chronic pain and substance abuse, are unmet medical needs. In this symposium, 4 speakers are going to present their extensive works on the roles of orexins in sleep, pain and reward regulations. The scope encompasses the basic sciences underlying these discoveries, and the translational potentials of the orexin system in clinical setting.
