Book excerpt: This project aims to investigate abnormalities in glutamate neurotransmission in the rat cortex following traumatic brain injury (TBI). The overarching hypothesis is that excessive glutamate release originating at the site of injury begins an excitotoxic cascade leading to increased intracellular calcium and cell death. Glutamate, the primary excitatory neurotransmitter in the mammalian central nervous system, facilitates learning, memory, and other cognitive functions via activation of metabotropic and ionotropic glutamate receptors. A family of Na+ - dependent excitatory amino acid transporters (EAATs) on the plasma membranes of neurons and glial cells facilitate the rapid removal of glutamate from the synaptic cleft, maintaining basal levels of synaptic glutamate. EAATs are also essential for the maintenance of extracellular glutamate concentrations below toxic levels. High levels of extracellular glutamate can initiate calcium-mediated signaling cascades, likely through activation of extracellular glutamate receptors. Alterations of extracellular glutamate reuptake following TBI may be a critical component in this excitotoxic cascade and presents a possible target for therapeutic intervention.Herein we demonstrated that TBI resulted in decreased EAAT-mediated glutamate reuptake capacity, and possible remolding of astrocytic processes due to injury iii induced signaling abnormalities. This was evaluated by measuring [3H]-glutamate reuptake and glutamate transporter protein expression profiles. The synaptosomal isolation protocol provides a functional characterization of glutamate clearance following TBI that may allow for the comparison of novel and existing therapeutic drugs.

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.

This book was released on 2014-02-04 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, few subjects at the intersection of medicine and sports have generated as much public interest as sports-related concussions - especially among youth. Despite growing awareness of sports-related concussions and campaigns to educate athletes, coaches, physicians, and parents of young athletes about concussion recognition and management, confusion and controversy persist in many areas. Currently, diagnosis is based primarily on the symptoms reported by the individual rather than on objective diagnostic markers, and there is little empirical evidence for the optimal degree and duration of physical rest needed to promote recovery or the best timing and approach for returning to full physical activity. Sports-Related Concussions in Youth: Improving the Science, Changing the Culture reviews the science of sports-related concussions in youth from elementary school through young adulthood, as well as in military personnel and their dependents. This report recommends actions that can be taken by a range of audiences - including research funding agencies, legislatures, state and school superintendents and athletic directors, military organizations, and equipment manufacturers, as well as youth who participate in sports and their parents - to improve what is known about concussions and to reduce their occurrence. Sports-Related Concussions in Youth finds that while some studies provide useful information, much remains unknown about the extent of concussions in youth; how to diagnose, manage, and prevent concussions; and the short- and long-term consequences of concussions as well as repetitive head impacts that do not result in concussion symptoms. The culture of sports negatively influences athletes' self-reporting of concussion symptoms and their adherence to return-to-play guidance. Athletes, their teammates, and, in some cases, coaches and parents may not fully appreciate the health threats posed by concussions. Similarly, military recruits are immersed in a culture that includes devotion to duty and service before self, and the critical nature of concussions may often go unheeded. According to Sports-Related Concussions in Youth, if the youth sports community can adopt the belief that concussions are serious injuries and emphasize care for players with concussions until they are fully recovered, then the culture in which these athletes perform and compete will become much safer. Improving understanding of the extent, causes, effects, and prevention of sports-related concussions is vitally important for the health and well-being of youth athletes. The findings and recommendations in this report set a direction for research to reach this goal.

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.

This book was released on 2024-07-01 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traumatic brain injury (TBI) remains one of healthcare's most significant challenges and policy making. TBI could not only lead to long-term functional impairment but also a decrease in quality of life. Lowering the mortality risk and benefitting survivors' living quality remains the target of neurotrauma studies globally. With the advent of novel TBI-related clinical and basic research approaches, diagnostics, therapeutics research, and novel and multidisciplinary methods have emerged. Despite promising progress, no completely effective treatment prevents or minimizes TBI and its related neurological and psychiatric sequelae. Understanding the mechanisms underlying the pathophysiology, treatment progress, and clinically based translational and engineering research on TBI may pave the way for potential treatment targets, diagnostic markers, and preventive methods that ultimately lead to efficacious therapeutic strategies. This Research Topic aims to disseminate high-quality TBI and related research, especially for the compositive and in-depth study in integration, translation, and multidisciplinary approaches in TBI research, including new technology and research methods in clinical neurology, new findings in neuroendocrinology, neuropathology and new development in neuropharmacology, neurophysiology. This Research Topic is focused on novel developments, current challenges, future perspectives, and especially interdisciplinary research in the field of TBI.
