Neuroimmune Diseases

A translational overview of neuroimmune diseases for neuroscientists and clinicians that clarifies the pathological mechanisms underlying neuroimmune diseases and builds a comprehensive bridge between the latest research findings and their clinical implications in daily practice. The material is presented in two steps. The first section comprises a review of the pathogenic actions of immune cells in brain diseases. Here the authors discuss the mechanisms through which immune cells disrupt the functions of nerve cells. The second section explores the ways in which the brain becomes dysfunctional due to impaired nerve cell function. Based on pathogenesis, diagnostic and therapeutic strategies are discussed for each clinical category. The book will be invaluable for use in clinical practice of neuroimmune diseases

This book offers a detailed review of the remarkable advances that have been made in research on the pathogenesis of a number of neuroimmunological diseases, as well as outlining novel treatments including the use of monoclonal antibodies. Written by renowned experts who have made major contributions in the field, such as identifying neuromyelitis optica as an immunopathological clinical condition, identifying the role of ganglioside and ganglioside-complex antibodies in Guillain-Barré syndrome, and developing a novel treatment for POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes) syndrome, the book summarizes recent advances in basic and clinical research. Neuroimmunological Diseases is a useful resource for not only researchers but also neurologists who are engaged in the management of neuroimmunological diseases.

Introduction and Perspectives This volume is based on the proceedings of the 7th annual symposium on the topic Neuroimmune Circuits, Infectious Diseases and Drugs of Abuse, Bethesda, Maryland, Oc- ber 7–9, 1999. This symposium, as in the past, focused on newer knowledge concerning the relationship between the immune and nervous systems with regards to the effects of drugs of abuse and infections, including AIDS, caused by the immunodeficiency virus. Presentations discussed the brain-immune axis from the viewpoint of drugs of abuse rather than from the subject of the brain or immunity alone. The major aim of this series of conferences has been to clarify the consequences of immunomodulation induced by drugs of abuse in regards to susceptibility and pathogenesis of infectious diseases, both in man and in various animal model systems. The recreational use of drugs of abuse such as morphine, cocaine, and marijuana by large numbers of individuals in this country and around the world has continued to arouse serious concerns about the consequences of use of such drugs, especially on the normal physiological responses of an individual, including immune responses. Much of the recent data accumulated by investigators show that drugs of abuse, especially opioids and cannabinoids, markedly alter immune responses in human populations as well as in experimental animals, both in vivo and in vitro.

This book provides a clinical focus on neuroinflammatory diseases as well as a review in pathophysiology and treatment approaches. Organized into six parts, the book begins with a basic review of the immune system and concepts for learning and treating neuroimmune conditions. The next four sections cover specific subfields of neuroimmunology and autoimmune neurology - the clinical and diagnostic features of multiple sclerosis, other autoimmune conditions of the central nervous system, autoimmune conditions of the peripheral nervous system, and systemic autoimmune conditions that affect the nervous system. To conclude, Section six discusses various clinical approaches to specific presentations in neuroimmunology, including pediatric demyelinating diseases. These sections provide practical clinical information to improve the reader’s knowledge in this complex field. The chapters are written by world renown authors with extensive knowledge to help provide up to date information. The full scope of autoimmune neurology is discussed, which is a unique feature of this book. Neuroimmunology serves as a resource for those in training including residents and fellows to provide clear clinical reasoning and background in a rapidly advancing field.

A Primer of Neuroimmunological Disease is a significant new resource for anyone interested in conditions such as multiple sclerosis(MS), myasthenia gravis, and neurological infections. It is a practical and balanced guide to the diagnosis and treatment of neuroimmunological disease. A Primer of Neuroimmunological Disease distinguishes itself by providing a range of features not generally included in texts on neuroimmunology. These include broad presentation of information in the form of figures and tables; strong cohesion among topics by focusing on a few prototypic neuroimmunological diseases, which serve as a foundation from which to explore other neuroimmunological diseases; a single author perspective, with references across chapters; and a focus on the overlap between neuroimmunological and neuroinfectious diseases. Neurologists, immunologists, infectious disease specialists, neuroscientists and others interested in neuroimmunological diseases such as MS will find A Primer of Neuroimmunological to be a state-of-the-art resource.

It is now well appreciated that the immune system, in addition to its traditional role in defending the organism against pathogens, communicate in a well-organized fashion with the brain to maintain homeostasis and regulate a set of neural functions. Perturbation in this brain-immune interactions due to inflammatory responses may lead to psychiatric and neurological disorders. Microglia are one of the essential cells involved in the brain-immune interactions. Microglial cells are now not simply regarded as resident tissue macrophages in the brain. These cells are derived from myeloid progenitor cells in the yolk sac in early gestation, travel to the brain parenchyma and interact actively with neurons during the critical period of neurogenesis. Microglia provide a trophic support to developing neurons and take part in the neural wiring through the activity-dependent synapse elimination via direct neuron-microglia interactions. Altered microglial functions including changes in the gene expression due to early life inflammatory events or psychological and environmental stressors can be causally related to neurodevelopmental diseases and mental health disorders. This type of alterations in the neural functions can occur in the absence of infiltration of inflammatory cells in the brain parenchyma or leptomeninges. In this sense, the pathogenetic state underlying a significant part of psychiatric and neurological diseases may be similar to “para-inflammation”, an intermediate state between homeostatic and classical inflammatory states as defined by Ruslan Medzhitov (Nature 454:428-35, 2008). Therefore, it is important to study how systemic inflammation affects brain health and how local peripheral inflammation induces changes in the brain microenvironment. Chronic pain is also induced by disturbance in otherwise well-organized multisystem interplay comprising of reciprocal neural, endocrine and immune interactions. Especially, early-life insults including exposure to immune challenges can alter the neuroanatomical components of nociception, which induces altered pain response later in life. Recently the discrete roles of microglia and blood monocyte-derived macrophages are being defined. The distinction may be further highlighted by disorders in which the brain parenchymal tissue is damaged. Therefore, studies investigating the dynamics of immune cells in traumatic brain injury and neurotropic viral infections including human immunodeficiency virus, etc. as well as neurodegenerative diseases such as amyotrophic lateral sclerosis are promising to clarify the interplay between the central nervous and immune systems. The understanding of the histological architecture providing the infrastructure of such neuro-immune interplay is also essential. This Frontiers research topic brings together fourteen articles and aims to create a platform for researchers in the field of psychoneuroimmunology to share the recent theories, hypotheses and future perspectives regarding open questions on the mechanisms of cell-cell interactions with chemical mediators among the nervous, immune and endocrine systems. We hope that this platform would reveal the relevance of the studies on multisystem interactions to enhance the understanding of the mechanisms underlying a wide variety of neurological and psychiatric disorders.
