Molecular And Cellular Therapies For Motor Neuron Diseases

Molecular and Cellular Therapies for Motor Neuron Diseases discusses the basics of the diseases, also covering advances in research and clinical trials. The book provides a resource for students that will help them learn the basics in a detailed manner that is required for scientists and clinicians. Users will find a comprehensive overview of the background of Amyotrophic Lateral Sclerosis (ALS/Lou Gehrig’s Disease) and Spinal Muscular Atrophy (SMA), along with the current understanding of their genetics and mechanisms. In addition, the book details gene and cell therapies that have been developed and their translation to clinical trials. Provides an overview of gene and cell therapies for amyotrophic lateral sclerosis (ALS) and other motor neuron diseases Edited by a leading Neurosurgeon and two research scientists to promote synthesis between basic neuroscience and clinical relevance Presents a great resource for researchers and practitioners in neuroscience, neurology, and gene and cell therapy

Dedicated to our readers, we include novel information (not reported in IntechOpen’s books before) about new contributions of aberrant astrocytes to MND damage and death in the SOD1G93A rat experimental model of ALS; novel genetic studies on ALS; an update of the structural and functional consequences of the spinal muscular atrophy-linked mutations of the survival motor neuron protein; stem cell therapy for MND; and the novel treatment for SMA and ALS in the introductory chapter. This book contains selected peer-reviewed chapters written by international researchers. In this publication, the readers will find a compilation of state-of-the-art reviews about etiology, therapies, investigations, the molecular basis of disease progression and clinical manifestations, and the genetic familial ALS, as well as novel therapeutic modalities. We look forward with confidence and pride to the remarkable role that this book will play for a new vision and mission.

In this e-book, motor neuron disease (MND) shall refer to amyotrophic lateral sclerosis (ALS), the most common neurodegenerative disorder affecting both the upper and lower motor neurons. With the discovery of C9ORF72 expansions in approximately 10% of all MND cases, in certain populations, we stand at the brink of a new era of MND research and hopefully treatment facilitated by the ability to associate a relatively large group of patients with a similar disease mechanism. This review will summarise both current clinical management of MND and our present understanding of the molecular pathogenesis of MND. Study of C9ORF72-MND has the potential to rapidly advance both of these aspects in the coming years.

Written and designed to provide comprehensive, easily accessible advice for all healthcare professionals involved in the care of patients with this challenging condition, this book addresses the entire care pathway from presentation to diagnosis to symptom management and end of life issues.

Amyotrophic lateral sclerosis (ALS), which was described since 1869 by Jean Martin Charcot, is a devastating neurodegenerative disease characterized by the selective and progressive loss of upper and lower motor neurons of the cerebral cortex, brainstem and the spinal cord. The cognitive process is not affected and is not merely the result of aging because may occur at young ages. The only known cause of the disease is associated with genetic mutations, mainly in the gene encoding superoxide dismutase 1 (familial ALS), whereas there is no known cause of the sporadic form of ALS (SALS), which comprises >90% of cases. Both ALS types develop similar histopathological and clinical characteristics, and there is no treatment or prevention of the disease. Because effective treatments for ALS, as for other neurodegenerative diseases, can only result from the knowledge of their cellular and molecular pathophysiological mechanisms, research on such mechanisms is essential. Although progress in neurochemical, physiological and clinical investigations in the last decades has identified several mechanisms that seem to be involved in the cell death process, such as glutamate-mediated excitotoxicity, alterations of inhibitory circuits, inflammatory events, axonal transport deficits, oxidative stress, mitochondrial dysfunction and energy failure, the understanding of the origin and temporal progress of the disease is still incomplete and insufficient. Clearly, there is a need of further experimental models and approaches to discern the importance of such mechanisms and to discover the factors that determine the selective death of motor neurons characteristic of ALS, in contrast to other neurodegenerative diseases such as Parkinson’s and Alzheimer’s disease. Whereas studies in vitro in cell cultures, tissue slices or organotypic preparations can give useful information regarding cellular and molecular mechanisms, the experiments in living animal models obviously reflect more closely the situation in the human disease, provided that the symptoms and their development during time mimics as close as possible those of the human disease. It is necessary to correlate the experimental findings in vitro with those in vivo, as well as those obtained in genetic models with those in non-genetic models, aiming at designing and testing therapeutic strategies based on the results obtained.

'Motor Neuron Disease in Adults' reviews new information from 1998 as it applies to all aspects of motor neuron disease. Articles included use evidence-based methods to ensure that the new information is solid and advances the topic. The book can be used by anyone who provides any type of care to ALS patients.

The Molecular and Cellular Basis of Neurodegenerative Diseases: Underlying Mechanisms presents the pathology, genetics, biochemistry and cell biology of the major human neurodegenerative diseases, including Alzheimer’s, Parkinson’s, frontotemporal dementia, ALS, Huntington’s, and prion diseases. Edited and authored by internationally recognized leaders in the field, the book's chapters explore their pathogenic commonalities and differences, also including discussions of animal models and prospects for therapeutics. Diseases are presented first, with common mechanisms later. Individual chapters discuss each major neurodegenerative disease, integrating this information to offer multiple molecular and cellular mechanisms that diseases may have in common. This book provides readers with a timely update on this rapidly advancing area of investigation, presenting an invaluable resource for researchers in the field. Covers the spectrum of neurodegenerative diseases and their complex genetic, pathological, biochemical and cellular features Focuses on leading hypotheses regarding the biochemical and cellular dysfunctions that cause neurodegeneration Details features, advantages and limitations of animal models, as well as prospects for therapeutic development Authored by internationally recognized leaders in the field Includes illustrations that help clarify and consolidate complex concepts

The Molecular and Clinical Pathology of Neurodegenerative Disease brings together in one volume our current understanding of the molecular basis of neurodegeneration in humans, targeted at neuroscientists and graduate students in neuroscience, and the biomedical and biological sciences. Bringing together up-to-date molecular biology data with clinical evidence, this book sheds a light on common molecular mechanisms that underlie many different neurodegenerative diseases and addresses the molecular pathologies in each. The combined research and clinical background of the authors provides a unique perspective in relating clinical experiences with the molecular understanding needed to examine these diseases and is a must-read for anyone who wants to learn more about neurodegeneration.
