Multiple sclerosis (MS) is one of the most common neurological disorders in young adults. The etiology of MS is not known, but it is generally accepted that it is autoimmune in nature. Our knowledge of the pathogenesis of MS has increased tremendously in the past decade through clinical studies and the use of experimental autoimmune encephalomyelitis (EAE), a model that has been widely used for MS research. Major advances in the field, such as understanding the roles of pathogenic Th17 cells, myeloid cells, and B cells in MS/EAE, as well as cytokine and chemokine signaling that controls neuroinflammation, have led to the development of potential and clinically approved disease-modifying agents (DMAs). There are many aspects related to the initiation, relapse and remission, and progression of MS that are yet to be elucidated. For instance, what are the genetic and environmental risk factors that promote the initiation of MS, and how do these factors impact the immune system? What factors drive the progression of MS, and what are the roles of peripheral immune cells in disease progression? How do the CNS-infiltrated immune cells interact with the CNS-resident glial cells when the disease progresses? What is the role of microbiome in MS? Can we develop animal models that better represent subcategories of MS? Understanding the cellular and molecular mechanisms that govern the pathogenesis of MS will help to develop novel and more specific therapeutic strategies that will ultimately improve clinical outcomes of the treatments. This Special Issue of Cells has published original research articles, a retrospective clinical report, and review articles that investigate the cellular and molecular basis of MS.

"Multiple sclerose (MS) is a chronic inflammatory disease of the central nervous system (CNS), in which autoimmune demyelination leads to severe and progressive neurologic decline. A hallmark of MS is its clinical and pathological heterogeneity. This is most evident in the highly variable and unpredictable disease course: some MS patients may remain relatively asymptomatic for decades, whereas others may progress to a state of severe disability and death within years or in cases with fulminant disease even within months after onset. Strongly implicated in the heterogeneity of MS are inter-individual differences in cortisol production by the hypothalamus-pituitary-adrenal (HPA)-axis. In most MS patients, the HPA-axis is strongly activated. However, we and others identified an association between low HPA-axis activity and more severe MS. Therefore, this thesis aimed to provide a better understanding of the relation between activity and regulation of the HPA-axis and various aspects of MS: clinical course, neurodegeneration, lesion pathology, glucocorticoid receptor (GR) polymorphisms, and molecular as well as cellular characteristics of normal-appearing white matter (NAWM). On the whole, this thesis supports the conclusion that high stress-axis activity substantially contributes to suppression of MS disease activity, as the presented evidence strongly suggests that it impacts on clinical course, lesion pathology as well as cellular and molecular mechanisms in the NAWM. Finding ways to evaluate and possibly modify stress-axis responsiveness to inflammation might therefore improve the clinical care of MS patients. In addition, identifying mechanisms to modulate microglia and glucocorticoid-related molecular pathways in the NAWM may represent a valuable therapeutic strategy for preventing lesion formation and disease progression in MS."--Samenvatting auteur.

Despite major efforts by the scientific community over the years, our understanding of the pathogenesis or the mechanisms of injury of multiple sclerosis is still limited. Consequently, the current strategies for treatment and management of patients are limited in their efficacy. The mechanisms of tissue protection and repair are probably even less understood. One reason for these limitations is the enormous complexity of the disease and every facet of its pathogenesis, the mechanisms of tissue injury, the diagnostic procedures and finally the efficacy of treatments and their side effects. The aim of this book is to review the most recent advances made in this highly complex field.

Multiple sclerosis is a chronic and often disabling disease of the nervous system, affecting about 1 million people worldwide. Even though it has been known for over a hundred years, no cause or cure has yet been discovered-but now there is hope. New therapies have been shown to slow the disease progress in some patients, and the pace of discoveries about the cellular machinery of the brain and spinal cord has accelerated. This book presents a comprehensive overview of multiple sclerosis today, as researchers seek to understand its processes, develop therapies that will slow or halt the disease and perhaps repair damage, offer relief for specific symptoms, and improve the abilities of MS patients to function in their daily lives. The panel reviews existing knowledge and identifies key research questions, focusing on: Research strategies that have the greatest potential to understand the biological mechanisms of recovery and to translate findings into specific strategies for therapy. How people adapt to MS and the research needed to improve the lives of people with MS. Management of disease symptoms (cognitive impairment, depression, spasticity, vision problems, and others). The committee also discusses ways to build and financially support the MS research enterprise, including a look at challenges inherent in designing clinical trials. This book will be important to MS researchers, research funders, health care advocates for MS research and treatment, and interested patients and their families.

Taken together, we have provided evidence for two potential mechanisms of disease remission, one involving interactions between death inducing ligands and their receptors, and another using immunoregulatory cells. This study provides keen insight and far-ranging implications in not only understanding the pathogenesis of autoimmune diseases like multiple sclerosis, but also in the design of therapeutic applications and regimens for their subsequent treatment.

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 provides cutting-edge information on the epidemiology, etiopathogenesis, clinical manifestations, diagnostic procedures and treatment approaches for the main white matter (WM) disorders of the central nervous system (CNS). WM lesions are associated with many neurological conditions, and with aging. The diagnostic work-up of neurological diseases characterized by the presence of these lesions has changed dramatically over the past few years. This is mainly due on the one hand to the discovery of specific pathogenetic factors in some of these conditions, and on the order to the optimized use of diagnostic tools. All of this has resulted in new diagnostic algorithms, and in the identification of new neurological conditions. The book offers neurologists essential guidance in the diagnosis and treatment of the most frequent WM conditions, promoting their correct and cost-saving diagnosis and management. By integrating neurological, laboratory and imaging concepts with the demands of accurate diagnosis, this reference guide provides a state-of-the-art overview of the current state of knowledge on these conditions, as well as practical guidelines for their diagnosis and treatment.
