Download or read book Glutamate Related Biomarkers in Drug Development for Disorders of the Nervous System written by Institute of Medicine and published by National Academies Press. This book was released on 2011-08-05 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glutamate is the most pervasive neurotransmitter in the central nervous system (CNS). Despite this fact, no validated biological markers, or biomarkers, currently exist for measuring glutamate pathology in CNS disorders or injuries. Glutamate dysfunction has been associated with an extensive range of nervous system diseases and disorders. Problems with how the neurotransmitter glutamate functions in the brain have been linked to a wide variety of disorders, including schizophrenia, Alzheimer's, substance abuse, and traumatic brain injury. These conditions are widespread, affecting a large portion of the United States population, and remain difficult to treat. Efforts to understand, treat, and prevent glutamate-related disorders can be aided by the identification of valid biomarkers. The Institute of Medicine's Forum on Neuroscience and Nervous System Disorders held a workshop on June 21-22, 2010, to explore ways to accelerate the development, validation, and implementation of such biomarkers. Glutamate-Related Biomarkers in Drug Development for Disorders of the Nervous System: Workshop Summary investigates promising current and emerging technologies, and outlines strategies to procure resources and tools to advance drug development for associated nervous system disorders. Moreover, this report highlights presentations by expert panelists, and the open panel discussions that occurred during the workshop.

Download or read book The Glutamate GABA Glutamine Cycle written by Arne Schousboe and published by Springer. This book was released on 2016-11-25 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamental biochemical studies of basic brain metabolism focusing on the neuroactive amino acids glutamate and GABA combined with the seminal observation that one of the key enzymes, glutamine synthetase is localized in astroglial cells but not in neurons resulted in the formulation of the term “The Glutamate-Glutamine Cycle.” In this cycle glutamate released from neurons is taken up by surrounding astrocytes, amidated by the action of glutamine synthetase to glutamine which can be transferred back to the neurons. The conversion of glutamate to glutamine is like a stealth technology, hiding the glutamate molecule which would be highly toxic to neurons due to its excitotoxic action. This series of reactions require the concerted and precise interaction of a number of enzymes and plasma membrane transporters, and this volume provides in-depth descriptions of these processes. Obviously such a series of complicated reactions may well be prone to malfunction and therefore neurological diseases are likely to be associated with such malfunction of the enzymes and transporters involved in the cycle. These aspects are also discussed in several chapters of the book. A number of leading experts in neuroscience including intermediary metabolism, enzymology and transporter physiology have contributed to this book which provides comprehensive discussions of these different aspects of the functional importance of the glutamate-glutamine cycle coupling homeostasis of glutamatergic, excitatory neurotransmission to basic aspects of brain energy metabolism. This book will be of particular importance for students as well as professionals interested in these fundamental processes involved in brain function and dysfunction.

Download or read book Glutamate written by J. Storm-Mathisen and published by Elsevier. This book was released on 2000-11-03 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume presents a comprehensive and up-to-date treatise of the glutamatergic synapse and its environment. Particular emphasis is on the localizations of the molecular constituents of the synaptic machinery. Immunogold and other high-resolution methods are used extensively. Each chapter presents new data that have not previously been reviewed. The material presented forms the basis for work directed to understanding the functional properties of excitatory synapses in greater depth, to discover mechanisms of neurological and psychiatric disorders and novel methods for treatment. Chapter 1 deals with the transmitter molecule itself, mechanisms of release and pathways for glutamate synthesis. The anatomy of glutamatergic nerve projection pathways in different brain regions is dealt with. In Chapter 2, focus is on aspartate, the enigmatic congener of glutamate, and its possible role in excitatory neurotransmission. Chapters 3 through 6 deal with glutamate receptors. Metabotropic glutamate receptors are presented in Chapter 3. Chapter 4 presents an in situ hybridization atlas of the different classes of ionotropic glutamate receptors. The localizations of these receptors at the regional and synaptic level are presented in Chapter 5. The ways in which the receptors are brought to the synapse and held in position are the subject of Chapter 6. Chapter 7 deals with the enzymes responsible for formation and catabolism of glutamate. In Chapter 8, the regulation of extracellular glutamate levels by glutamate transporters is discussed. The final two chapters of the volume focus on two "model synapses" that, due to special features, lend themselves particularly well to demonstrating properties of glutamatergic synapses. The hair cell-to-afferent nerve terminal synapses in the inner ear (Chapter 9), with their supporting cells, share essential properties with glutamatergic synapses in the central nervous system. The salient features of the latter are illustrated by the synapses of the giant reticulo-spinal axons of the lamprey, used to unravel molecular mechanisms of the cycling of synaptic vesicles (Chapter 10).

Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Download or read book Glutamate and GABA Receptors and Transporters written by Jan Egebjerg and published by CRC Press. This book was released on 2001-10-04 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ubiquitous presence of glutamate and GABA receptors in the nervous system makes these receptor systems pivotal to our understanding of neurotransmission. Cloning of the molecular components of these receptor systems has provided insights to the selectivity of many drugs and detailed characterisation at the molecular level is emerging. Moreover, continuous development of novel and selective drugs has revealed detailed information on the mechanism of receptor activation and regulation. However, the rapid development of different aspects of glutamate and GABA receptor research makes it increasingly difficult to establish a general view of the field. Studies of the receptors are a multi-disciplinary task employing many specialised techniques. This book conveys recent discoveries in a framework of the basic concepts in the field of glutamate and GABA receptor research. Glutamate and GABA Receptors and Transporters: Structure, Function and Pharmacology is suitable for postgraduate students studying ligand gated channels but also beneficial for industrial and academic research scientists in both the glutamate and GABA field. Universities offering programs in neuroscience, molecular pharmacology or medicinal chemistry will find this a valuable reference.

Download or read book Amino Acids of the Glutamate Family Functions beyond Primary Metabolism written by Sakiko Okumoto and published by Frontiers Media SA. This book was released on 2016-10-07 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The life of proteins starts and ends as amino acids. In addition to the primary function as protein building blocks, amino acids serve multiple other purposes to make a plant's life worth living. This is true especially for the amino acids of the glutamate family, namely glutamate (Glu), glutamine (Gln), proline (Pro) and arginine (Arg), as well as the product of Glu decarboxylation, ?-aminobutyric acid (GABA). Synthesis, accumulation, interconversion and degradation of these five compounds contribute in many ways to the regulation of plant development and to responses to environmental challenges. Glu and Gln hold key positions as entry points and master regulators of nitrogen metabolism in plants, and have a pivotal role in the regulatory interplay between carbon and nitrogen metabolism. Pro and GABA are among the best-studied compatible osmolytes that accumulate in response to water deficit, yet the full range of protective functions is still to be revealed. Arg, with its exceptionally high nitrogen-to-carbon ratio, has long been recognized as a major storage form of organic nitrogen. Most of the enzymes involved in metabolism of the amino acids of the glutamate family in plants have been identified or can be predicted according to similarity with animal or microbial homologues. However, for some of these enzymes the detailed biochemical properties still remain to be determined in order to understand activities in vivo. Additionally, uncertainties regarding the subcellular localization of proteins and especially the lack of knowledge about intracellular transport proteins leave significant gaps in our understanding of the metabolic network connecting Glu, Gln, Pro, GABA and Arg. While anabolic reactions are distributed between the cytosol and chloroplasts, catabolism of the amino acids of the glutamate family takes place in mitochondria and has been implicated in fueling energy-demanding physiological processes such as root elongation, recovery from stress, bolting and pollen tube elongation. Exceeding the metabolic functions, the amino acids of the glutamate family were recently identified as important signaling molecules in plants. Extracellular Glu, GABA and a range of other metabolites trigger responses in plant cells that resemble the actions of Glu and GABA as neurotransmitters in animals. Plant homologues of the Glu-gated ion channels from mammals and protein kinase signaling cascades have been implicated in these responses. Pollen tube growth and guidance depend on GABA signaling and the root architecture is specifically regulated by Glu. GABA and Pro signaling or metabolism were shown to contribute to the orchestration of defense and programmed cell death in response to pathogen attacks. Pro signaling was additionally proposed to regulate developmental processes and especially sexual reproduction. Arg is tightly linked to nitric oxide (NO) production and signaling in plants, although Arg-dependent NO-synthases could still not be identified. Potentially Arg-derived polyamines constitute the missing link between Arg and NO signaling in response to stress. Taken together, the amino acids of the glutamate family emerge as important signaling molecules that orchestrate plant growth and development by integrating the metabolic status of the plant with environmental signals, especially in stressful conditions. This research topic collects contributions from different facets of glutamate family amino acid signaling or metabolism to bring together, and integrate in a comprehensive view the latest advances in our understanding of the multiple functions of Glu-derived amino acids in plants.

Download or read book Glutamate Receptors in Peripheral Tissue written by Santokh Gill and published by Springer Science & Business Media. This book was released on 2007-01-31 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glutamate receptors (GluRs) in the central nervous system have been the subject of intense investigations for several decades, providing new avenues for the understanding of excitatory neurotransmission, excitotoxicity, mechanisms of injury, and therapeutics for several acute neurological conditions, such as brain trauma, and for neurodegenerative and neuropsychiatric disorders including addictions, Alzheimer disease, etc. Evidences of GluRs beyond the central nervous system were first reported in the early 1990s. When the idea of this book was conceived, the knowledge, specificity, and functional significance of GluRs in peripheral tissues was still in its embryonic stage. From our perspective, the idea of GluRs in peripheral tissues arose from our research on seafood toxins (see Chapter 1), and has now been reinforced by the results of other scientists working in similar areas. In this book, we have invited some of the leading authorities in the field to summarize their findings and to provide a framework for further investigations. The book is divided into three sections— Part I is on general concepts and concentrates on the distribution and cell-specific localiza tion of glutamate receptors, their transporters, and the pharmacology in peripheral tissues and organs. Part II emphasizes the presence and implications of these receptors in specific target tissues, organs, and systems, including liver, lungs, endocrine tissues, bone, immune system, etc. Part III focuses on glutamate receptors in plants to illustrate their presence beyond the animal kingdom.
