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.

BOOK EXCERPT:
In recent years increased scientific attention has been given to immediate defense mechanisms based on non-clonal recognition of microbial components. These mechanisms constitute the innate immunity arm of the body s defense. Identification of pathogens by these mechanisms involves primarily receptors recognizing sugar moieties of various microorganisms. Innate immunity based mechanisms are essential for the existence of multicellular organisms. They are evolutionarily conserved and designed to provide immediate protection against microbial pathogens to eradicate infection. Activation of innate immunity is crucial for transition to specific immunity and for its orientation, and to assist the specific immune response in the recognition of pathogens and their destruction. Innate immunity is regularly involved in the arrest of bacterial, mycotic, viral and parasitic infections, giving the specific immune response time to become effective. It becomes critically essential in immunocompromised patients who fail to mount specific immune responses due to congenital or acquired immunodeficiencies as a result of chemotherapy, dialysis, immunosuppressive drugs, or HIV infection. The Innate Immunity arsenal constitutes polymorphonuclear and mononuclear phagocytes, mast cells, the complement system, Natural Killer cells, antimicrobial peptides, and presumably a subset of T lymphocytes with TCRl receptors.

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

BOOK EXCERPT:
Neurodegenerative diseases share the common property of neuronal loss in the higher-order association and limbic cortices or the extrapyramidal and pyramidal motor systems. In addition, oligodendroglia, astrocytes, and microglia have been implicated in fundamental abnormalities of virtually every neurodegenerative disorder. The particular system affected, more importantly the distribution of the pathology, determines the clinical presentation. While the most common dementia and movement disorders, such as Alzheimer’s disease, Lewy body disease, and frontotemporal lobar degeneration with TDP-43 pathology, including amyotrophic lateral sclerosis, have been extensively studied, many less common, even rare neurodegenerative disorders have gained more attention in recent years. This shift in focus is perhaps driven, in part, by the severely underestimated financial costs associated with these diseases, as well as the immense emotional burden they impose on patients and their caregivers. This book presents the most recent developments in rare neurodegenerative disorders. Insights gained from the investigation of pathophysiological mechanisms of these rare disorders may lead to the development of therapeutic strategies for more prevalent neurodegenerative disorders. In addition to highlighting advancements in research, the book discusses the significant challenges faced by researchers and healthcare professionals in diagnosing and treating rare diseases. It emphasizes the critical need for continued funding and support for research, which is essential to improving patient outcomes and advancing our understanding of these complex conditions.
