Book Description
Schwann cells are a diverse group of cells formed from neural crest cells. They are essential components of the peripheral nerves of both vertebrate and invertebrate nervous systems. The diversity of Schwann cell subsets and function is seen in those Schwann cells that form myelin - that uniquely specialised part of the plasma membrane that spirals around axonal lengths to myelinate the peripheral nerves. The Biology of Schwann Cells concentrates on the cells of mammals and in particular humans. It covers the distinction between compact and non-compact myelin in depth, along with the perisynaptic cells which form the partnership between nerve terminals and muscle fibre. Developmental aspects are discussed alongside differentiation, and the genetics of the cells in health and disease. With chapters from world-renowned experts, this book is aimed at postgraduates and researchers in neuroscience and neurology and anyone involved in the study of peripheral nerves.

Book Description
The fundamental roles of Schwann cells during peripheral nerve formation and regeneration have been recognized for more than 100 years, but the cellular and molecular mechanisms that integrate Schwann cell and axonal functions continue to be elucidated. Derived from the embryonic neural crest, Schwann cells differentiate into myelinating cells or bundle multiple unmyelinated axons into Remak fibers. Axons dictate which differentiation path Schwann cells follow, and recent studies have established that axonal neuregulin1 signaling via ErbB2/B3 receptors on Schwann cells is essential for Schwann cell myelination. Extracellular matrix production and interactions mediated by specific integrin and dystroglycan complexes are also critical requisites for Schwann cell–axon interactions. Myelination entails expansion and specialization of the Schwann cell plasma membrane over millimeter distances. Many of the myelin-specific proteins have been identified, and transgenic manipulation of myelin genes have provided novel insights into myelin protein function, including maintenance of axonal integrity and survival. Cellular events that facilitate myelination, including microtubule-based protein and mRNA targeting, and actin based locomotion, have also begun to be understood. Arguably, the most remarkable facet of Schwann cell biology, however, is their vigorous response to axonal damage. Degradation of myelin, dedifferentiation, division, production of axonotrophic factors, and remyelination all underpin the substantial regenerative capacity of the Schwann cells and peripheral nerves. Many of these properties are not shared by CNS fibers, which are myelinated by oligodendrocytes. Dissecting the molecular mechanisms responsible for the complex biology of Schwann cells continues to have practical benefits in identifying novel therapeutic targets not only for Schwann cell-specific diseases but other disorders in which axons degenerate.

Book Description
This book presents recent topics on the development, differentiation, and myelination of Schwann cells, as well as pathological mechanisms and therapeutic approaches for peripheral neuropathies, such as Charcot–Marie–Tooth diseases, amyloid polyneuropathy, immune-mediated neuropathy and diabetic neuropathy. The rapid progress of molecular biological techniques in the last decades, especially for RNA techniques and gene modification technologies have allowed us to investigate the pathobiology of Schwann cells in vivo and in vitro. Studies combining recent stem cell biology with recent biotechnology, which is now closely linked to physicochemical fields, further explain how Schwann cell lineages develop a process that has long been thought to be very complicated in vivo. The findings contribute to the elucidation of fundamental mechanisms during development and under pathological conditions. We now know that these are closely tied to each other. This book also introduces unique coculture systems to reproduce the neuron–Schwann cell interplay during development, degeneration, and regeneration. Up-to-date research topics with high-quality immunofluorescence and electron micrographs introduced by young and energetic contributors are sure to arouse the readers' interest in Schwann cell biology. Discussion from the viewpoint of basic and clinical neuroscience makes the book educational for researchers, medical students and young clinicians.

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.

Book Description
The majority of cells in the nervous system are glial cells. During de velopment, these cells provide growth factors that stimulate the proli feration, migration and survival of neurones and their precursors, and promote and guide axonal growth. In the mature nervous system, glial cells provide insulating myelin sheath around axons and provide metabo lic and structural support for neurones. Glial cells also have a major influence on the local response to injury of central nerve tracts and the peripheral nervous system, either promoting, or inhibiting, axona l regrowth and recovery of lost function. This book provides a compreh ensive, state-of-the-art overview of research into the development, fu nction and malfunction of glial cells. It offers a compelling insight into how basic research throws light onto diseases and disorders and p oints the way towards treatments. Teams of internationally renowned ex perts, all active in research, have contributed chapters.

Book Description
The peripheral nervous system is usually defined as the cranial nerves, spinal nerves, and peripheral ganglia which lie outside the brain and spinal cord. To describe the structure and function of this system in one book may have been possible last century. Today, only a judicious selection is possible. It may be fairly claimed that the title of this book is not misleading, for in keeping the text within bounds only accounts of olfaction, vision, audition, and vestibular function have been omitted, and as popularly understood these topics fall into the category of special senses. This book contains a comprehensive treatment of the structure and function of peripheral nerves (including axoplasmic flow and trophic func tions); junctional regions in the autonomic and somatic divisions of the peripheral nervous system; receptors in skin, tongue, and deeper tissues; and the integrative role of ganglia. It is thus a handbook of the peripheral nervous system as it is usually understood for teaching purposes. The convenience of having this material inside one set of covers is already proven, for my colleagues were borrowing parts of the text even while the book was in manuscript. It is my belief that lecturers will find here the information they need, while graduate students will be able to get a sound yet easily read account of results of research in their area. JOHN 1.

Book Description
Thirty-five years ago, when Stephen Kuffler and his colleagues at Harvard initiated a new era of research on the properties and functions of neuroglial cells, very few neuro scientists were impressed at the time with the hypothesis that neuroglial cells could have another, though more subtle, role to play in the nervous system than to provide static support to neurons. Today, very few neuroscientists are unaware of the fact that multiple interactions between neurons and glial cells have been described, and that they consti tute the basis for understanding the function and the pathology of the nervous system. Glial cells outnumber neurons and make up about one-half of the bulk of the nervous system. They are divided into two major classes: first, the macroglia, which include astrocytes and oligodendrocytes in the central nervous system, and the Schwann cells in the peripheral nervous system; and second, the microglial cells. These different classes of glial cells have different functions and contribute in different ways in the devel opment, function, and the pathology of the nervous system.
