5-HT2A receptors are G-protein coupled receptors that are widely distributed throughout the brain, most notably on neuronal and glial cells. 5-HT2A receptors have been implicated in various central physiological functions including mood regulation, memory, sleep, nociception, eating, and reward behaviors, and they are also believed to control the cardiovascular system. This book provides a comprehensive overview of these receptors including sections on their properties and distribution, approaches for their study, their role in a number of brain functions and diseases, and their role as therapeutic targets.

GABA is the principal inhibitory neurotransmitter in the CNS and acts via GABAA and GABAB receptors. Recently, a novel form of GABAA receptor-mediated inhibition, termed “tonic” inhibition, has been described. Whereas synaptic GABAA receptors underlie classical “phasic” GABAA receptor-mediated inhibition (inhibitory postsynaptic currents), tonic GABAA receptor-mediated inhibition results from the activation of extrasynaptic receptors by low concentrations of ambient GABA. Extrasynaptic GABAA receptors are composed of receptor subunits that convey biophysical properties ideally suited to the generation of persistent inhibition and are pharmacologically and functionally distinct from their synaptic counterparts. This book highlights ongoing work examining the properties of recombinant and native extrasynaptic GABAA receptors and their preferential targeting by endogenous and clinically relevant agents. In addition, it emphasizes the important role of extrasynaptic GABAA receptors in GABAergic inhibition throughout the CNS and identifies them as a major player in both physiological and pathophysiological processes.

This book provides a unique and timely multidisciplinary synthesis of our current knowledge of the anatomy, pharmacology, physiology and pathology of the substantia nigra pars compacta (SNc) dopaminergic neurons. The single chapters, written by top scientists in their fields, explore the life cycle of dopaminergic neurons from their birth to death, the cause of Parkinson's disease, the second most common and disabling condition in the elderly population. Nevertheless, the intracellular cascade of events leading to dopamine cell death is still unknown and, consequently, treatment is symptomatic rather than preventive. The mechanisms by which alterations cause neuronal death, new therapeutic approaches and the latest evidence of a possible de novo neurogenesis in the SNc are reviewed and singled out in different chapters. This book bridges basic science and clinical practice and will prepare the reader for the next few years, which will surely be eventful in terms of the progress of dopamine research.

Metabotropic glutamate receptors (mGluRs) are members of the group C family of G-protein-coupled receptors. Eight different mGlu subtypes have been identified and classified into three groups based on amino acid sequence similarity, agonist pharmacology, and the signal transduction pathways to which they couple. They perform a variety of functions in the central and peripheral nervous systems, being involved in learning, memory, anxiety, and the perception of pain. They are found in pre- and postsynaptic neurons in synapses of the hippocampus, cerebellum, and cerebral cortex, as well as other parts of the brain and peripheral tissues. This volume comprises the latest contributions of experts in the field on the role of mGlu receptor in health and disease, following the 8th International meeting on these receptors.

G-protein-coupled receptors (GPCRs) are believed to be the largest family of membrane proteins involved in signal transduction and cellular responses. They dimerize (form a pair of macromolecules) with a wide variety of other receptors. The proposed book will provide a comprehensive overview of GPCR dimers, starting with a historical perspective and including, basic information about the different dimers, how they synthesize, their signaling properties, and the many diverse physiological processes in which they are involved. In addition to presenting information about healthy GPCR dimer activity, the book will also include a section on their pathology and therapeutic potentials.

Research of 5-HT2c receptors stretches back twenty-five years, and while much of it has been productive, the past decade of research has been extraordinary in terms of both amount produced and insights gained. It is hardly surprising that 5-HT2c receptor research has grown so fruitful, given that it is a prominent central serotonin receptor subtype widely expressed within the central and the peripheral nervous system and is thought to play a major role in the regulation of numerous behaviors. It has further been shown by experimental and clinical observation that it may represent a possible therapeutic target for the development of drugs for a range of central nervous system disorders. The time, therefore, is more than appropriate to offer the first ever overview of the research of 5-HT2c receptors. Part of the popular and important series, “The Receptors,” The 5-HT2c Receptor provides a thorough update of the functional status of the 5-HT2c receptor. It covers the molecular, cellular, anatomical, biochemical and behavioral aspects of this receptor so as to highlight its distinctive regulatory properties and the emerging functional significance of constitutive activity and RNA-editing in vivo. In addition, the book investigates the receptors’ therapeutic potential in a range of different diseases, treated individually in separate chapters, including depression, drug abuse, schizophrenia, eating disorders, Parkinson’s disease, Prader-Willi Syndrome, Alzheimer’s disease and epilepsy. While not exhaustive, this text is a vital tool in understanding the past and inspiring the future of interdisciplinary research on the 5-HT2c receptor.
