Dynamics of Degeneration and Growth in Neurons


Book Description

Dynamics of Degeneration and Growth in Neurons is a collection of papers presented at the International Symposium on the Dynamics of Degeneration and Growth in Neurons, held in Stockholm, Sweden, on May 16-18, 1973. Contributors explore the dynamics of degeneration and growth of central and peripheral neurons, touching on a wide range of topics such as the neurotoxic action of 6-hydroxy-dopa on central catecholamine neurons; axonal transport of proteins in growing and regenerating neurons; and collateral reinnervation in the central nervous system. Comprised of 50 chapters, this volume begins with an overview of degeneration processes in central and peripheral neurons. Results of microfluorimetric and neurochemical studies on degenerating and regenerating adrenergic nerves are presented. The next section is devoted to axoplasmic transport as a mechanism for axonal support and growth and includes chapters dealing with the effects of degeneration and axoplasmic transport blockade on synaptic ultrastructure, function, and protein composition; the role of axoplasmic flow in trophism of skeletal muscle; and proximodistal transport of acetylcholine in peripheral cholinergic neurons. The remaining chapters discuss the nerve growth factor receptor and its specific binding in sympathetic ganglia; the noradrenergic innervation of cerebellar Purkinje cells; and the possible role of brain and peripheral monoamines in the ontogenesis of normal and drug-induced responses in the immature mammal. This book will be of interest to physiologists and neurologists.










Degeneration and Regeneration in the Nervous System


Book Description

Degeneration and Regeneration in the Nervous System brings together an international team of contributors to produce a series of critical reviews appraising key papers in the field. The pace of research on brain and spinal cord injury quickened considerably in the last ten years and there is much that is new and important that is covered in this book. However, there is still a long way to go before our knowledge will explain fully why the central nervous system has such a limited capacity for regeneration, and before experimental solutions can be applied to the patient. With emphasis on actual and therapeutic importance of the work reviewed, Degeneration and Regeneration in the Nervous System is a useful overview for graduate students, their teachers and researchers working in this field.







Wiring the Nervous System: Mechanisms of Axonal and Dendritic Remodelling in Health and Disease


Book Description

This book examines recent key findings on the mechanisms of axonal and dendritic remodeling in different model organisms. Each chapter is contributed by a panel of experts in their respective subfields of neurosciences, to provide and discuss the latest discoveries ranging from neuronal morphogenesis during development, experience-dependent structural plasticity, to neuronal degeneration, regeneration, and pathologies in neurological disorders. The process of neuronal remodeling, specifically their axons and dendrites, is essential for the proper wiring of the nervous system during early development and continues during postnatal ages to shape the pattern of synaptic connections throughout the life of the organism, including humans. Over recent years, substantial progress has been made in our understanding of the cellular and molecular mechanisms that control neuronal remodeling. In addition, there is accumulating evidence demonstrating how the nervous system could remodel in response to injury and in pathological conditions. Topics discussed in the book include: Axonal degeneration during development and in pathological or disease conditions Neuronal morphogenesis (axons and dendrites) Experience-dependent structural plasticity to synaptogenesis Dendrite degeneration and regeneration




Neuronal Degeneration and Regeneration: From Basic Mechanisms to Prospects for Therapy


Book Description

This book is the result of the 20th International Summer School in Brain Research, organized in August 1997 in Amsterdam, by the Netherlands Institute for Brain Research at the Royal Netherlands Academy of Sciences. It is the first book that provides a complete overview of the field of neurodegeneration and regeneration including spinal cord injury, neurodegenerative diseases and therapy. Divided into five sections, the first two sections give an overview of fundamental research on nerve cell death, neuronal survival, neurite outgrowth and guidance. Extensive attention is given to the role of neurotrophins, their receptor tyrosine kinases and cell-adhesion molecules in development and regeneration of the nervous system. The third section of the book is devoted to research involving human neurodegenerative diseases and emerging treatment strategies. Section four focusses on recent advances in the understanding of pathophysiological mechanisms underlying neurodegenerative diseases, including Alzheimer's, Parkinson's and Huntington's diseases along with prion diseases. Novel insights into the neuropathological hallmarks of these diseases, as well as into transgenic animal models, the involvement of environmental factors, and genomic and mRNA changes that can cause neurodegeneration. The final section of this volume reveals recent developments in the use of cell and gene therapy to treat neurodegenerative disease and lesion-related deficits. Implantation of genetically modified cells, direct gene transfer with viral vectors and the first clinical trials with encapsulated genetically modified cells in patients suffering from amyotrophic lateral scelerosis are examples of new therapeutic strategies treating neurodegenerative diseases.The book is of particular interest to departments of neuroscience, neurological clinics and departments, the pharmalogical industry and medical libraries.




Axon Degeneration


Book Description

This book is a collection of classical as well as innovative methods used to investigate axon degeneration with a particular focus on addressing the common challenges encountered while performing these procedures. Particular attention is devoted to the study of axon loss in several model organisms, as each poses unique challenges and provides powerful advantages. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Axon Degeneration: Methods and Protocols is an ideal guide for facilitating the application and further development of these protocols, which will help the scientific community tackle important questions regarding axon degeneration.

The Axon


Book Description

The axon, interposed between the cell body and the synaptic terminals in most neurons, plays a crucial role in connecting neurons and acting as a conduit for the transmission of information between them. This book provides a comprehensive and up-to-date compendium that brings together chapterson the structure, function, and pathophysiology of axons in both the PNS and CNS. Carefully written, well-illustrated with superb illustrations, and generously referenced, the 33 chapters and introduction have been authored by 49 world-renowned authorities. Recent advances in the molecularneurobiology of axons are carefully reviewed, and new areas, such as the molecular biology of ion channels and myelination, the role of calcium in pathophysiology and regeneration, cell adhesion molecules and their roles in axo-glial interactions and axonal guidance, and optical recording methods,are highlighted. This book will provide an essential reference for neuroscientists as well as clinicians such as neurologists, neurosurgeons, and clinical electrophysiologists interested in axons.
