Impairment of orexin/hypocretin signaling causes narcolepsy-cataplexy in animals and humans. Most human narcolepsy-cataplexy cases are associated with orexin/hypocretin ligand deficiency, which can be detected clinically using cerebrospinal orexin/hypocretin measures and may lead to future treatments with orexin/hypocretin replacement therapy. In The Orexin/Hypocretin System: Physiology and Pathophysiology, leading researchers and clinicians review these exciting developments to set the stage for further research on the loss of orexin/hypocretin neurons in humans, regulation of sleep and wakefulness by the orexin/hypocretin system, and the role of the orexin/hypocretin system in many other physiological processes, including feeding, autonomic regulation, and neuroendocrine regulation. Topics of interest include an assessment of the functions and the physiology of orexin/hypocretin, its pathophysiology in human narcolepsy-cataplexy, and possible pharmacological treatments. The authors also introduce several experimental methods for orexin/hypocretin research, and, using multidisciplinary approaches, explain their uses and limitations. Authoritative and state-of-the-art, The Orexin/Hypocretin System: Physiology and Pathophysiology will aid scientists in the search for novel bioactive peptides and their receptors, as well as novel physiological insights and opportunities for the clinical treatment of not only narcolepsy, but also a broad range of diseases associated with endocrine, feeding, and body weight regulation.

Orexin/hypocretin neuropeptides, produced by a few thousand neurons in the lateral hypothalamus, are of critical importance for the control of vigilance and arousal of vertebrates, from fish to amphibians, birds and mammals. Two orexin peptides, called orexin-A and orexin-B, exist in mammals. They bind with different affinities to two distinct, widely distributed, excitatory G-protein- coupled receptors, orexin receptor type 1 and type 2 (OXR-1/2). The discovery of an OXR mutation causing canine narcolepsy, the narcolepsy-like phenotype of orexin peptide knockout mice, and the orexin neuron loss associated with human narcoleptic patients laid the foundation for the discovery of small molecule OXR antagonists as novel treatments for sleep disorders. Proof of concept studies from Glaxo Smith Kline, Actelion Pharmaceuticals Ltd. and Merck have now consistently demonstrated the efficacy of dual OXR antagonists (DORAs) in promoting sleep in rodents, dogs, non-human primates and humans. Some of these antagonists have completed late stage clinical testing in primary insomnia. Orexin drug discovery programs have also been initiated by other large pharmaceutical companies including Hoffmann La Roche, Novartis, Eli Lilly and Johnson & Johnson. Orexins are increasingly recognized for orchestrating the activity of the organism’s arousal system with appetite, reward and stress processing pathways. Therefore, in addition to models of insomnia, pharmacological effects of DORAs have begun to be investigated in rodent models of addiction, depression and anxiety. The first clinical trials in diabetic neuropathy, migraine and depression have been initiated with Merck’s MK-6096 (www.clinicaltrials.gov). Whereas the pharmacology of DORAs is established for their effects on wakefulness, pharmacological effects of selective OXR-1 or OXR-2 antagonists (SORAs) have remained less clear. From an evolutionary point of view, the OXR-2 was expressed first in most vertebrate lineages, whereas the OXR-1 is believed to result from a gene duplication event, when mammals emerged. Yet, both receptors do not have redundant function. Their brain expression pattern, their intracellular signaling, as well as their affinity for orexin-A and orexin-B differs. During the past decade most preclinical research on selective OXR-1 antagonism was performed with SB-334867. Only in recent years, other selective OXR-1 and OXR-2 antagonists with optimized selectivity profiles and pharmacokinetic properties have been discovered, and phenotypes of OXR-1 and OXR-2 knockout mice were described. The present Research Topic (referred to in the Editorial as “special topics issue”) comprises submissions of original research manuscripts as well as reviews, directed towards the neuropharmacology of OXR antagonists. The submissions are preclinical papers dealing with dual and/or selective OXR antagonists that shed light on the differential contribution of endogenous orexin signaling through both OXRs for cellular, physiological and behavioral processes. Some manuscripts also report on convergence or divergence of DORA vs. SORA effects with phenotypes expressed by OXR-1 or OXR-2 knockout animals. Ultimately these findings may help further define the potential of DORAs and SORAs in particular therapeutic areas in insomnia and beyond insomnia.

The first report that rapid eye movements occur in sleep in humans was published in 1953. The research journey from this point to the realization that sleep consists of two entirely independent states of being (eventually labeled REM sleep and non-REM sleep) was convoluted, but by 1960 the fundamental duality of sleep was well established including the description of REM sleep in cats associated with “wide awake” EEG patterns and EMG suppression. The first report linking REM sleep to a pathology occurred in 1961 and a clear association of sleep onset REM periods, cataplexy, hypnagogic hallucinations and sleep paralysis was fully established by 1966. When a naïve individual happens to observe a full-blown cataplexy attack, it is both dramatic and unnerving. Usually the observer assumes that the loss of muscle tone represents syncope or seizure. In order to educate health professionals and the general public, Christian Guilleminault and I made movies of full-blown cataplectic episodes (not an easy task). We showed these movies of cataplexy attacks to a number of professional audiences, and were eventually rewarded with the report of a similar abrupt loss of muscle tone in a dog. We were able to bring the dog to Stanford University and with this as the trigger, we were able to develop the Stanford Canine Narcolepsy Colony. Breeding studies revealed the genetic determinants of canine narcolepsy, an autosomal recessive gene we termed canarc1. Emmanuel Mignot took over the colony in 1986 and began sequencing DNA, finally isolating canarc1 in 1999.

Over the years, approaches to obesity prevention and treatment have gone from focusing on genetic and other biological factors to exploring a diversity of diets and individual behavior modification interventions anchored primarily in the power of the mind, to the recent shift focusing on societal interventions to design "temptation-proof" physical, social, and economic environments. In spite of repeated calls to action, including those of the World Health Organization (WHO), the pandemic continues to progress. WHO recently projected that if the current lifestyle trend in young and adult populations around the world persist, by 2012 in countries like the USA, health care costs may amount to as much as 17.7% of the GDP. Most importantly, in large part due to the problems of obesity, those children may be the first generation ever to have a shorter life expectancy than that of their parents. Obesity Prevention presents the most current research and proposals for addressing the pandemic. Past studies have focused primarly on either genetic or behavioral causes for obesity, however today's research indicates that a strongly integrated program is the best prospect for success in overcoming obesity. Furthermore, focus on the role of society in establishing an affordable, accessible and sustainable program for implementing these lifestyle changes is vital, particularly for those in economically challenged situations, who are ultimately at the highest risk for obesity. Using studies from both neuroscience and behavioral science to present a comprehensive overview of the challenges and possible solutions, The brain-to-society approach to obesity prevention focuses on what is needed in order to sustain a healthy, pleasurable and affordable lifestyle. Explores the "brain-to-society" approach to obesity prevention, focusing on an integrative approach to addressing the obesity pandemic Presents both the nueroscientific and the behavioral factors that impact eating habits Identifies the challenges and suggests solutions for altering attitudes toward food on both an individual and a societal level

Abstract Histaminergic and orexin/hypocretin systems are components in the brain wake‐promoting system. Both are affected in the sleep disorder narcolepsy, but the role of histamine in narcolepsy is unclear. The histaminergic neurones are activated by the orexin/hypocretin system in rodents, and the development of the orexin/hypocretin neurones is bidirectionally regulated by the histaminergic system in zebrafish. This review summarizes the current knowledge of the interactions of these two systems in normal and pathological conditions in humans and different animal models.

Narcolepsy serves as a prototype of how the interaction of high quality clinical research and groundbreaking basic science can collaborate to defne the cause of a disease and change forever how we evaluate and treat it. There is scarcely a topic in this book that would have been covered in the same way 10 years ago as it is d- cussed today. We are also fortunate that many of the players in this dramatic tu- around have contributed to this volume, so that the result is a tapestry of the events that have transformed the feld over the last decade that is both authentic and detailed. The frst section of the book provides much of the basic science background. As described in the frst two chapters, the dramatic convergence of lines of evidence from two different laboratories frst demonstrated in 1999 that narcolepsy is a disease of loss of neurotransmission by lateral hypothalamic neurons making the peptides that have been called orexins or hypocretins. These fndings did much to clarify and unify a feld that had puzzled for decades over the fundamental nature of this puzzling disease, as refected in the chapters that review its epidemiology and neuroanatomical and imaging fndings.

The human hypothalamus, a small structure at the base of the brain, has strategic importance for the harmonic function of the human body. It controls the autonomic nervous system, neuroendocrine function, circadian and circannual rhythms, somatic activities, and behavior, and is situated at the borders between the brain and the body and the brain and the soul, meeting points for mind and body. The hypothalamus is involved in a wide range of higher mental functions, including attention, learning and reinforcement of mnemonic processes, emotional control, mood stability, and cognitive-emotional interactions. It also has a role to play in behavioral disorders, panic reactions, cluster headache, gelastic epilepsy, mental deficiency, periodic disorders, depression, autism, and schizophrenia, and in a substantial number of neurodegenerative diseases. It enlarges greatly the dimensions of the hypothalamic contribution in controlling psychosomatic equilibrium and retaining internal unity of the human existence.

This issue of Current Topics in Behavioral Neuroscience focuses on the neuropeptide orexin (hypocretin) and brings together scientists from around the world who will provide a timely discussion of how this peptide regulates behavior. This is a fast-moving field, and with the incorporation of novel technologies, new breakthroughs are likely to continue. For example, the use of optogenetic approaches has enabled the identification of the role of orexin-containing neurons in arousal states, critical for higher order functioning. From a clinical perspective, genetic polymorphisms in hypocretin/orexin and orexin receptors are implicated in a number of psychiatric disorders. In addition, advanced clinical trials are currently underway for orexin receptor antagonists in the treatment of insomnia and sleep disorders. We aim to capture a broad audience of basic scientists and clinicians.

The human genome encompasses ˜ 860 G protein-coupled receptors (GPCRs) including 374 non-chemosensory GPCRs. Half of these latter GPCRs recognize (neuro)peptides as natural ligands. GPCRs thus play a pivotal role in neuroendocrine communication. In particular, GPCRs are involved in the neuroendocrine control of feeding behavior, reproduction, growth, hydromineral homeostasis and stress response. GPCRs are also major drug targets and hence possess a strong potential for the development of innovative pharmaceuticals. The aim of this Research Topic was to assemble a series of review articles and original research papers on neuropeptide GPCRs and their ligands that would illustrate the different facets of the studies currently conducted in this domain.
