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.

Available in PDF, EPUB and Kindle. Book excerpt: A thrilling story of scientific detective work and medical potential that illuminates the newly understood role of microglia—an elusive type of brain cell that is vitally relevant to our everyday lives. “The rarest of books: a combination of page-turning discovery and remarkably readable science journalism.”—Mark Hyman, MD, #1 New York Times bestselling author of Food: What the Heck Should I Eat? NAMED ONE OF THE BEST BOOKS OF THE YEAR BY WIRED Until recently, microglia were thought to be helpful but rather boring: housekeeper cells in the brain. But a recent groundbreaking discovery has revealed that they connect our physical and mental health in surprising ways. When triggered—and anything that stirs up the immune system in the body can activate microglia, including chronic stressors, trauma, and viral infections—they can contribute to memory problems, anxiety, depression, and Alzheimer’s. Under the right circumstances, however, microglia can be coaxed back into being angelic healers, able to make brain repairs in ways that help alleviate symptoms and hold the promise to one day prevent disease. With the compassion born of her own experience, award-winning journalist Donna Jackson Nakazawa illuminates this newly understood science, following practitioners and patients on the front lines of treatments that help to “reboot” microglia. In at least one case, she witnesses a stunning recovery—and in others, significant relief from pressing symptoms, offering new hope to the tens of millions who suffer from mental, cognitive, and physical health issues. Hailed as a “riveting,” “stunning,” and “visionary,” The Angel and the Assassin offers us a radically reconceived picture of human health and promises to change everything we thought we knew about how to heal ourselves.
Download or read book Beyond Myalgic Encephalomyelitis Chronic Fatigue Syndrome written by Institute of Medicine and published by National Academies Press. This book was released on 2015-03-16 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS) are serious, debilitating conditions that affect millions of people in the United States and around the world. ME/CFS can cause significant impairment and disability. Despite substantial efforts by researchers to better understand ME/CFS, there is no known cause or effective treatment. Diagnosing the disease remains a challenge, and patients often struggle with their illness for years before an identification is made. Some health care providers have been skeptical about the serious physiological - rather than psychological - nature of the illness. Once diagnosed, patients often complain of receiving hostility from their health care provider as well as being subjected to treatment strategies that exacerbate their symptoms. Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome proposes new diagnostic clinical criteria for ME/CFS and a new term for the illness - systemic exertion intolerance disease(SEID). According to this report, the term myalgic encephalomyelitis does not accurately describe this illness, and the term chronic fatigue syndrome can result in trivialization and stigmatization for patients afflicted with this illness. Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome stresses that SEID is a medical - not a psychiatric or psychological - illness. This report lists the major symptoms of SEID and recommends a diagnostic process.One of the report's most important conclusions is that a thorough history, physical examination, and targeted work-up are necessary and often sufficient for diagnosis. The new criteria will allow a large percentage of undiagnosed patients to receive an accurate diagnosis and appropriate care. Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome will be a valuable resource to promote the prompt diagnosis of patients with this complex, multisystem, and often devastating disorder; enhance public understanding; and provide a firm foundation for future improvements in diagnosis and treatment.

Download or read book The Cerebral Circulation written by Marilyn J. Cipolla and published by Biota Publishing. This book was released on 2016-07-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.
Download or read book Neuroimmune Pharmacology written by Tsuneya Ikezu and published by Springer Science & Business Media. This book was released on 2008-03-21 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuroimmune pharmacology seeks to harness the immune system to provide pharmacological intervention to combat neurodegenerative diseases. This book provides a comprehensive overview of topics that embrace the link between the immune system and the pathogenesis of neurodegenerative disorders. Results from recent studies strongly suggest that a major part of the process in diseases including Alzheimer’s and Parkinson’s as well as Prion diseases, comes from changes in the innate and adaptive arms of the brain and peripheral immune systems. Thus, the book provides an in-depth study of numerous fields including immunology, pharmacology, neuroscience and neurovirology. It is accompanied by a CD-ROM that includes access to lectures, slide presentations, and question and answers on neuroimmune pharmacology.

Download or read book The Neuronal Environment written by Wolfgang Walz and published by Springer Science & Business Media. This book was released on 2001-12-26 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leading neuroscience researchers offer a fresh perspective on neuronal function by examining all its many components-including their pertubation during major disease states-and relate each element to neuronal demands. Topics range from the dependency of neurons on metabolic supply, as well as on both ion and transmitter homeostasis, to their close interaction with the myelin sheath. Also addressed are the astrocytic signaling system that controls synaptic transmission, the extracellular matrix and space as communication systems, the role of blood flow regulation in neuronal demand and in blood-brain barrier function, and inflammation and the neuroimmune system. Insightful and integrative, The Neuronal Environment: Brain Homeostasis in Health and Disease demonstrates a clear new understanding that neurons do not work in isolation, that they need constant interactions with other brain components to process information, and that they are not the only information processing system in the brain.
Download or read book New Translational Insights on Metabolic Syndrome Obesity Hypertension Diabetes and beyond written by Camille M. Balarini and published by Frontiers Media SA. This book was released on 2016-08-15 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metabolic syndrome (MetS) can be considered as a clustering of several risk factors such as obesity, hypertension, insulin resistance and dyslipidemia, which could lead to the development of diabetes and cardiovascular diseases (CVD). There are several underlying causes for MetS including overweight, physical inactivity and genetic factors. However, the underlying mechanisms that leads to MetS are still poorly understood. Therefore, the aim of this E-book is to provide a space where researchers holding different backgrounds could shed some light onto the pathophysiology of different risk factors involved in MetS, mostly from translational research worldwide.

Download or read book Beyond the borders The gates and fences of Neuroimmune interaction written by Javier Velázquez-Moctezuma and published by Frontiers E-books. This book was released on 2014-10-10 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuroimmunology is a rapidly growing emerging field at which two old sciences have converged to integrate two different types of responses into a single coherent response involving the coordinated action of both systems, neural and immune. During long time it was thought that both systems worked separately and in divergent pathways. The brain was considered an immunoprivileged site and the immune organs were deemed as independent of any neural influence and also of nervous innervation. Time has gone and has proven that the borders between both systems were merely artificial. Since the beginning of Neuroimmunology in the 1980s much work has been done to elucidate the gates and fences in neuro-immune interactions. Brain was shown to be under the continuous surveillance of the immune system, even under basal physiological conditions in the absence of any pathology. Likely, it was found a profuse nervous innervation of lymphoid organs and even of single immune cells. Gates for direct neural immune communication were found both centrally and peripherally. Centrally, the gates, but also the fences, were situated at the brain barriers, the blood-brain barrier and the blood-cerebrospinal fluid barrier, and at the circunventricular organs. Peripherally, the fences constituted the apparent diverse nature of molecules involved in neural and immune signaling; however, time proved that both system were capable of producing the same signaling molecules and also systematically responded to the molecules released by the other system. Therefore, the gates were open for direct neural-immune communication at the peripheral level. This Research Topic aimed to include original reports, reviews and technical reports regarding the description of the gates and fences in neural immune interactions. We intended to provide an extensive view of the mechanisms governing central and peripheral neural-immune interactions, and the role of the borders, the blood-neural barriers, in the regulation of the neural-immune communication.
Download or read book The Immunology of Cardiovascular Homeostasis and Pathology written by Susanne Sattler and published by Springer. This book was released on 2017-06-30 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiovascular immunology is a newly emerging research area, investigating the crosstalk between the cardiovascular and the immune system. This crosstalk is evident through (1) crucial immunological capacities and functions of cardiovascular cell types, including cardiomyocytes, fibroblasts, endothelial cells, pericytes and cardiac resident macrophages, (2) the impact of aberrant immune function on the development of cardiovascular disease such as atherosclerosis, direct and indirect immune-mediated heart disease and vasculitis, and (3) the crucial role of the immune system in cardiac repair and regeneration. The Immunology of Cardiovascular Homeostasis and Pathology covers all these aspects of cardiovascular immunology, starting with homeostatic immunological functions of traditional cardiovascular cell types, and moving then to the role of the immune system in cardiovascular pathology and to recent research into targeting the immune system to boost cardiac healing and regeneration.
