Book excerpt: Summary This thesis describes multiple central and peripheral immune cell changes during aging, in Alzheimer’s disease (AD), and multiple sclerosis (MS). In the first chapters of this thesis, we investigated the effect of aging on the immune system and searched for the aging factors involved. In the later chapters, we investigated the immune response to AD and MS pathology. Aging During aging, a general decline in immune function occurs, ultimately contributing to increased susceptibility to infections in the elderly. We found that microglial morphological complexity declines during aging and can be modulated by peripheral levels of glucocorticoids. We further discovered that peripheral factors can induce age-associated changes in the brain, and thus potentially counteract them. Consequently, we hypothesize that modulating peripheral immunity via plasma factors, such as hormones and cytokines, could combat brain aging and associated pathology. Alzheimer’s disease AD is a neurodegenerative disease that ultimately causes dementia. One of the pathological hallmarks is the deposition of abnormal tau protein in the brain. We found that this deposition induced reactive and dystrophic microglia with increased lysosomal volumes containing abnormal tau and postsynaptic structures. Together, this shows that tauopathy induces a loss of homeostatic microglia that is potentially linked to a loss of synapses. Peripheral immune cells are associated with neurodegenerative diseases as well, although fewer research attempts have investigated these cells in the context of AD. We analyzed the peripheral immune landscape of AD patients at the early and late stages of the disease and found that levels of circulating CD8+ T cells with an effector memory phenotype increased before the onset of dementia. These CD8+ T cells expressed markers associated with T cell senescence and terminal differentiation.

This book was released on 2012-12-06 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea that the brain is an "immune-privileged site" has perhaps served to slow our realization that the intact brain can generate its own inflammatory reactions. These responses can be to peripheral infection, or they can arise from local, internal causes, for instance as a response to stress or to the se vere changes in neuronal activity in seizure or the loss of oxygen in stroke. We are also becoming increasingly aware of the contribution of local inflam matory reactions to certain neurodegenerative diseases such as Alzheimer's In fact, evidence is accumulating that inflammatory processes disease (AD). contribute to the progression of AD, suggesting the possibility of using cur rently available or novel anti-inflammatory agents to interfere with this terri ble disease. Correlations are also being made between inflammatory signs and mental illness, which is a new frontier of research. This book presents the current state of knowledge in a variety of areas relevant to neuro-immune interactions, with particular attention to AD.

Available in PDF, EPUB and Kindle. Book excerpt: Inflammation of the brain in the context of neurodegenerative disorders is an area of intense debate and discussion, not least in terms of its pathogenic significance and the extent to which it drives disease processes and pathology. This inflammation can take several forms including innate responses recruiting microglia, humoral responses involving antibody, complement mediated processes and cellular T-cell activation, of which the role and extent of each may differ between diseases. Whilst some diseases have been more intensely linked to inflammation and long-term degeneration (e.g. MS), more traditional chronic neurodegenerative disorders have been thought of in terms of intrinsic neuronal pathology with a secondary innate response. However, it has been described that microglia activation is an early event of many degenerative disorders and evidence is accumulating that it may play a critical role in actually causing pathology and driving disease processes. If true, this would have major therapeutic implications, but what is the evidence that this is the case? The initial observations by Patrick McGeer’s group of post-mortem tissue from patients with Parkinson’s disease revealed the presence of activated brain microglia and has thus lead to the hypothesis that chronic inflammation could participate to neuronal degenerative processes. The significance of these original observations has only been recently revisited, and the development of more powerful tools to study the brain immune response has certainly contributed to this field of research. Chronic inflammation in the brain can take many forms but of particular interest has been the resident microglia and the role they play in this process. In this context, microglia have often been thought to become activated only after the disease has begun and then to contribute minimally to the degenerative process. Emerging new concepts challenge this view by proposing that microglial senescence, for example, may release the disease process and/or accelerate it. In addition, microglia, once activated, can adopt different phenotypes which can be both pro-inflammatory and pro-repair and may impact not only on the healthy adult neuronal population but on those new neurons derived from neurogenic niches of the adult brain. In this Research Topic, we attempt to explore this by first considering the innate immune responses in the brain and the methods by which they can be studied experimentally and in patients with various neurodegenerative disorders. This sets the scene for then discussing a range of different disorders including Alzheimer’s, Parkinson’s, Huntington’s disease and amyotrophic lateral sclerosis. These papers seek to discuss the evidence for an innate immune response and whether this is beneficial or detrimental, as well as its therapeutic implications.
Download or read book Clinical Relevance of the Immune to Brain and Brain to Immune Communications written by Julie Lasselin and published by Frontiers Media SA. This book was released on 2019-03-29 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental and clinical evidence demonstrates an intense crosstalk among the nervous, endocrine and immune systems. The central nervous system (CNS) not only has the capacity to affect peripheral immune function, but is also able to sense and process signals from the peripheral immune system. The bi-directional interaction between the CNS and the peripheral immune system has gained great interest as it can help better understand disease pathophysiology as well as improving health and treatment outcomes in patients. On the one hand, inflammatory factors are known to affect CNS functions and to induce neuropsychiatric symptoms, making immune-to-brain communication highly relevant for psychiatric diseases and their treatments. On the other hand, analyzing pathways of brain-to-immune communication will help to understand the pathophysiology of chronic inflammatory disorders and will form the basis for optimizing treatment of these diseases.

This book was released on 2021-11-16 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuroinflammation is the chronic inflammation of the nervous tissues. Its initiation could be due to different triggers of the immune system such as traumatic brain injury, infection and autoimmunity. During neuroinflammation, innate immune cells within the central nervous system, known as micrologia, are activated. Central nervous system is generally protected by a blood-brain barrier, but circulating peripheral immune cells can surpass it sometimes, which results in the immune response. Neuroinflammation is associated with neurodegenerative diseases such as multiple sclerosis, Alzheimer's disease and Parkinson's disease. Different approaches, evaluations and advanced studies on neuroinflammation have been included in this book. A number of latest researches are present to keep the readers up-to-date with the global concepts in this area of study. The extensive content of this book provides the readers with a thorough understanding of the subject.
Download or read book Glial Cells Managers of Neuro immunity written by Carlos Barcia and published by Frontiers Media SA. This book was released on 2016-05-30 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immune responses within the brain are still scarcely explored. Nerve tissue damage is accompanied by the activation of glial cells, primarily microglia and astroglia, and such activation is responsible for the release of cytokines and chemokines that maintain the local inflammatory response and actively recruit lymphocytes and monocytes to the damaged areas. Theoretically, these responses are designed to repair the brain damage. However, alterations, or a chronic perpetuation of these responses may underlie a number of neuro-pathologies. It is thought that each inflammatory scenario within the brain have a specific biochemical footprint characterized by the release of determined cytokines, chemokines and growing factors able to define particular immunological responses. Alongside, glial cells transform their cell body, become larger and develop higher number of branches adopting an active morphological phenotype. These changes are related with the search of interactions with other cells, such as bystander resident cells of the brain parenchyma, but also cells homing from the blood stream. In this process, microglia and astrocytes communicates with other cells by the formation of specific intercellular connections that are still poorly understood. These interactions are complex and entail the arrangement of cytoskeletal compounds, secretory and phagocytic domains. In this particular crosstalk there is a two-way communication in which glial cells and target cells come together establishing interfaces with specific information exchange. This way, glial cells orchestrate the particular response recruiting cellular subsets within the central nervous system and organizing the resolution of the brain damage. In this Frontiers Research Topic, we compile a selection of articles unfolding diverse aspects of glial-derived inflammation, focused on neurodegenerative diseases and other nervous system disorders, with special emphasis on microglia/macrophages as leading actors managing neuro-immunity.

Book excerpt: The Molecular Immunology of Neurological Diseases provides a comprehensive review of current updates in molecular immunogenetics of different neurological diseases. Readers will learn about the role of immune cells and their modulation strategies to help in the development of therapeutic approaches for both acute and chronic neurodegenerative disorders. There is no other book available on the topic. It has long been thought that the brain is an immune-privilege organ with very limited immune response. However recent studies have made clear that both systemic 'brain' and peripheral 'blood' immune cell responses play key roles in determining brain pathology in neurodegenerative disorders. This book summarizes the role of immune cell activation in the central nervous system microenvironment in acute and chronic neurodegenerative disorders. In addition, it discusses the key role of immune cells and their modulation strategies for the development of current therapeutic approaches. Discusses the molecular immunogenetics of different neurological diseases Covers strategies for the development of therapeutic approaches Encompasses both acute and chronic neurogenerative disorders Describes the molecular pathogenesis of viral genes in various diseases Features chapters on migraine, muscular dystrophy and cancer
Download or read book Neuroinflammation and CNS Disorders written by Nicola Woodroofe and published by John Wiley & Sons. This book was released on 2014-04-15 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last decade has seen an upsurge of information on the role of immune responses in neurodegenerative disorders. In many of these diseases it is still unclear whether the innate and adaptive responses are pathogenic or play a role in repair, and thus understanding their precise roles is key to controlling these diseases by designing immune-therapeutic approaches. The connection between many neurological diseases is the realisation that the immune and nervous systems are inextricable linked, and that perturbations in this delicate balance are involved in many disorders. This has opened up new avenues for therapeutic approaches to treatment of CNS inflammatory and neurodegenerative disorders. Neuroinflammation and CNS Disorders brings together the very latest information on the interactions between the immune system and central nervous system. The first section of the book highlights the basic concepts in the field whilst the second section, the main body of the book, covers the role of the immune response in specific disorders of the central nervous system. Neuroinflammation and CNS Disorders will provide an invaluable guide for both researchers and clinicians working in this complex and dynamic field.
