Book Description
Neuropeptides mediate their effects by binding and activating receptors that are responsible for converting these extracellular stimuli into intracellular responses. Most neuropeptides interact with G protein-coupled receptors that transduce the signal by activating heterotrimeric G proteins leading to alterations in second messenger systems to amplify the signal and elicit the intracellular response. In this review, we describe the general structure of G protein-coupled receptors including the information obtained from crystal structure determination that has given an insight into the activation mechanism of these receptors. In addition, we summarize the components of the signal transduction system (including G proteins, effectors and second messengers generally activated by the neuropeptide receptors). Using select examples of neuropeptide-receptor systems, we highlight the neuropeptides and corresponding receptors involved in modulation of pain and analgesia, body weight regulation, and hormonal regulation. Finally, we discuss the enzyme-linked tyrosine kinase receptors activated by growth factors and discuss the emerging concepts in targeting neuropeptide receptors for the identification of novel therapeutics targeting these systems.

Book Description
Peptide Receptors Part I was published in 2000 (as volume 16 of the Handbook of Chemical Neuroanatomy series). This volume summarized current knowledge on the discrete anatomical distribution of ten families of neuropeptide receptors expressed in the mammalian CNS. Part II is its natural complement with chapters covering six additional families of neuropeptide receptors for ligands ranging from well known peptides such as the opioids and neurotensin to recently isolated ones like the orexins. As in the case of Part I, this volume integrates photomontages and maps of quantitative receptor autoradiography, in situ hybridization histochemistry and immunocytochemistry. Data derived from transgenic and knock-out animals are also summarized, helping to decipher the possible physiological and Pathophysiological role(s) of a given peptide family. Some chapters also review current knowledge on the profile of internalization of the neuropeptide-receptor complex, an area of intense research activities that should help to better understand mechanisms involved in desensitization and tachyphylaxis.

Book Description
Molecular Neuroendocrinology: From Genome to Physiology, provides researchers and students with a critical examination of the steps being taken to decipher genome complexity in the context of the expression, regulation and physiological functions of genes in neuroendocrine systems. The 19 chapters are divided into four sectors: A) describes and explores the genome, its evolution, expression and the mechanisms that contribute to protein, and hence biological, diversity. B) discusses the mechanisms that enhance peptide and protein diversity beyond what is encoded in the genome through post-translational modification. C) considers the molecular tools that today’s neuroendocrinologists can use to study the regulation and function of neuroendocrine genes within the context of the intact organism. D) presents a range of case studies that exemplify the state-of-the-art application of genomic technologies in physiological and behavioural experiments that seek to better understand complex biological processes. • Written by a team of internationally renowned researchers • Both print and enhanced e-book versions are available • Illustrated in full colour throughout This is the third volume in a new Series ‘Masterclass in Neuroendocrinology’ , a co- publication between Wiley and the INF (International Neuroendocrine Federation) that aims to illustrate highest standards and encourage the use of the latest technologies in basic and clinical research and hopes to provide inspiration for further exploration into the exciting field of neuroendocrinology.

Book Description
The need to continually discover new agents for the control or treatment of invertebrate pests and pathogens is undeniable. Agriculture, both animal and plant, succeeds only to the extent that arthropod and helminth consumers, vectors and pathogens can be kept at bay. Humans and their companion animals are also plagued by invertebrate parasites. The deployment of chemical agents for these purposes inevitably elicits the selection of resistant populations of the targets of control, necessitating a regular introduction of new kinds of molecules. Experience in other areas of chemotherapy has shown that a thorough understanding of the biology of disease is an essential platform upon which to build a discovery program. Unfortunately, investment of research resources into understanding the basic physiology of invertebrates as a strategy to illuminate new molecular targets for pesticide and parasiticide discovery has been scarce, and the pace of introduction of new molecules for these indications has been slowed as a result. An exciting and so far unexploited area to explore in this regard is invertebrate neuropeptide physiology. This book was assembled to focus attention on this promising field by compiling a comprehensive review of recent research on neuropeptides in arthropods and helminths, with contributions from many of the leading laboratories working on these systems.

Book Description
This textbook is the first to bring together and synthesize the neuropeptide research of the past decade in such a comprehensive, scholarly manner. In recent years there has been increasing interest and, subsequently, active research in neuropeptides. These neuroactive molecules coordinate, integrate, and regulate physiological processes in all organisms, throughout all phases of development. Acting as neurohormones, neurotransmitters, and/or neuromodulators, they maintain physiological homeostasis and influence important behavioral patterns. This textbook is the first to bring together and synthesize the neuropeptide research of the past decade in such a comprehensive, scholarly manner. The book is divided into two parts. In Part I the author defines the basic principles of neuropeptide action, including their biosynthesis, processing, transport, distribution, and interactions with receptors and second messenger systems. Strand also discusses the intimate interaction between the neuropeptides, stress, and the immune system. In Part II she discusses the regulatory functions of the families of neuropeptide in sufficient detail to provide both the advanced student and senior investigator with a thorough understanding of the most important neuropeptides. The text also contains a complete and up-to-date reference/reading list.

Book Description
Over the last decade it has been shown that orphan G protein-coupled receptors (GPCRs) can be used as targets to discover novel neuropeptides. A dozen neuropeptides have been identified through this approach. Each of these neuropeptides has opened new doors for our understanding of fundamental physiological or behavioral responses. For example the orexins, MCH and ghrelin carry fundamental roles in regulating food intake while neuropeptide S, neuromedin S, the prokineticins and the orexins are major players in modulating sleep and circadian rhythms. The chapters of this book review the latest research in the field, most of them are written by the original discoverers of the respective novel neuropeptide. Emphasis is set not only on their discovery but also on their functional significance. Since many of these neuropeptides are part of drug discovery programs, this book impacts academic as well as pharmaceutical research.
