The Biology of Oligodendrocytes


Book Description

Traditionally, oligodendrocytes have been assumed to play a minor supporting role in the central nervous system and their importance has generally been overlooked. For the first time, this book provides a dedicated review of all of the major aspects of oligodendrocyte biology, including development, organization, genetics, and immunobiology. Later chapters emphasize the importance of this underestimated cell to the mammalian central nervous system by exploring the role of myelin synthesis and maintenance in neural disease and repair. Particular attention is paid to multiple sclerosis (MS), arguably the prime example of an acquired demyelinating disease, with detailed examinations of the current concepts regarding demyelination, oligodendroglial damage, and remyelination in MS lesions.

The Glutamate/GABA-Glutamine Cycle


Book Description

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.

Oligodendrocyte Physiology and Pathology Function


Book Description

The adult vertebrate central nervous system mainly consists of neurons, astrocytes, microglia cells, and oligodendrocytes. Oligodendrocytes, the myelin-forming cells of the CNS, are subjected to cell stress and subsequent death in a number of metabolic or inflammatory disorders, among which multiple sclerosis (MS) is included. This disease is associated with the development of large demyelinated plaques, oligodendrocyte destruction, and axonal degeneration, paralleled by the activation of astrocytes and microglia as well as the recruitment of peripheral immune cells to the site of tissue injury. Of note, viable oligodendrocytes and an intact myelin sheath are indispensable for neuronal health. For example, it has been shown that oligodendrocytes provide nutritional support to neurons, fast axonal transport depends on proper oligodendrocyte function, and mice deficient in mature myelin proteins eventually display severe neurodegeneration. This Special Issue contains a collection of highly relevant primary research articles as well as review articles focusing on the development, physiology, and pathology of the oligodendrocyte–axon–myelin unit.




Glial Neurobiology


Book Description

"This volume is a very valuable and much needed contribution." –Quarterly Review of Biology AT LAST - A comprehensive, accessible textbook on glial neurobiology! Glial cells are the most numerous cells in the human brain but for many years have attracted little scientific attention. Neurophysiologists concentrated their research efforts instead, on neurones and neuronal networks because it was thought that they were the key elements responsible for higher brain function. Recent advances, however, indicate this isn’t exactly the case. Not only are astroglial cells the stem elements from which neurones are born, but they also control the development, functional activity and death of neuronal circuits. These ground-breaking developments have revolutionized our understanding of the human brain and the complex interrelationship of glial and neuronal networks in health and disease. Features of this book: an accessible introduction to glial neurobiology including an overview of glial cell function and its active role in neural processes, brain function and nervous system pathology an exploration of all the major types of glial cells including: the astrocytes, oligodendrocytes and microglia of the ACNS and Schwann cells of the peripheral nervous system; the book also presents a broad overview of glial receptors and ion channels an investigation into the role of glial cells in various types of brain diseases including stroke, neurodegenerative diseases such as Alzheimer's, Parkinson's and Alexander's disease, brain oedema, multiple sclerosis and many more a wealth of illustrations, including unique images from the authors' own libraries of images, describing the main features of glial cells Written by two leading experts in the field, Glial Neurobiology provides a concise, authoritative introduction to glial physiology and pathology for undergraduate/postgraduate neuroscience, biomedical, medical, pharmacy, pharmacology, and neurology, neurosurgery and physiology students. It is also an invaluable resource for researchers in neuroscience, physiology, pharmacology and pharmaceutics.
