Available in PDF, EPUB and Kindle. Book excerpt: This PIR volume presents a comprehensive collection of reviews that focus on the role of the blood-brain barrier (BBB) during steady-state and inflamed conditions. Within the central nervous system (CNS) the constantly changing bloodstream is strictly separated from the CNS parenchyma by the BBB. However, viruses, bacteria, parasites and auto-aggressive immune cells can penetrate the barrier and significantly contribute to CNS inflammation. The BBB can actively contribute to neuroinflammation by presentation of chemokines, expression of cell adhesion molecules and alterations of barrier properties. As such, understanding the role of the BBB under healthy and pathological conditions is essential to the development of new drugs to efficiently combat inflammatory diseases of the CNS.

Download or read book Inflammation and Epilepsy New Vistas written by Damir Janigro and published by Springer Nature. This book was released on 2021-05-18 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides comprehensive information, both for clinicians and scientists, on the basic mechanisms, clinical features, and therapeutic approaches to epilepsy as an inflammatory disease. Inflammation has been for many years considered as an etiologic player (and a therapeutic target) for a specific group of epilepsies. However, it turns out that this concept underestimated the impact of inflammation in seizure disorders. Many accepted therapies for non-inflammatory epilepsies act in part as an inflammatory drug. The CNS actively responds to acute immune challenges by altering body temperature, stimulating the HPA axis, as well as up- and down-regulating specific sympathetic pathways.
Download or read book Systemic Inflammatory Regulation of Blood brain Barrier Inflammation written by Rebecca Johnson and published by . This book was released on 2019 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The endothelial cells of the blood-brain barrier are essential for the maintenance of homeostasis in the central nervous system. These cells act as a physical and transport barrier, restricting the movement of systemic immune cells and blood components into the brain. The physical barrier is mediated by the formation of tight and adherens junctions, and the redistribution of these in disease states and systemic inflammation, and the consequent extravasation of immune cells provide valuable targets to reduce neuroinflammation. Multiple Sclerosis is an autoimmune disease in which autoreactive T cells mediate the destruction of the neuronal myelin sheath, leading to a reduction in the speed of neuronal processing, and numerous debilitating symptoms. Blood-brain barrier breakdown is essential to the development of MS, and endothelial cell morphology is vastly different within sites of active lesions and normal appearing white matter. This study attempted to determine the in vitro effect of MS patient serum on the integrity of the endothelial cell barrier and to identify barrier altering components. Individual cytokines which altered the endothelial cell barrier were further analysed to determine their effect on junctional protein expression and the pro-inflammatory secretome. Additionally, the effects of ligands of the toll-like receptor family, a family of innate immune pattern recognition receptors were also analysed, to simulate the effect of systemic bacterial or viral infection at the blood-brain barrier. Interestingly, it was found that the FDA-approved TLR7 ligand imiquimod could increase the endothelial barrier integrity and attenuate the effects of pro-inflammatory stimuli in a TLR7-independent manner. The pathways by which imiquimod was mediating these effects were interrogated, and it was observed that both a cAMP-dependent selective protein kinase A-activator and adenosine A2B receptor agonist could recreate these effects. However, an A2B receptor antagonist did not block the imiquimod-mediated effects. The endothelial cells of the blood-brain barrier are an essential interface between the systemic circulation and the brain. These findings provide novel insights into the effect of pro-inflammatory mediators at this interface and identify potential targets for the modulation of blood-brain barrier permeability and the attenuation of pro-inflammatory insults.
Download or read book Inflammation and Stroke written by Giora Z. Feuerstein and published by Springer. This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stroke is a leading cause of death in developed countries. However, current therapeutic strategies for stroke have been largely unsuccessful. One possible explanation is that research and pharmacological management have focused on very early events in brain ischemia. New research has shown that brain ischemia and trauma elicit strong inflammatory reactions driven by both external and brain cells. The recognition of inflammation as a fundamental response to brain ischemia provides novel opportunities for new anti-inflammatory therapies. For the first time, an international body of researchers presents the latest findings about the cellular and humoral aspects of immune and inflammatory reactions in the brain. The work may have an impact on the treatment of neuroinjuries and ancillary brain diseases, and increase the understanding of the roles infections and immune reactions play in the brain milieu.

This book was released on 2008-11-09 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years, the immune and central nervous systems were thought to function independently with little or no interaction between the two. This view has und- gone dramatic changes over the past three decades. Indeed, we now know that there exists various feedback loops between the brain and immune systems that impact signi cantly upon different behavioral processes, including normal behavior and mental disorders. Pioneering efforts in generating this change were initiated by a number of early investigators. Included were those whose efforts were directed at establishing neuroimmune connections as well as others whose research focused upon the relationship between immunity, cytokines, and behavior. This book brings together outstanding scientists and clinicians who have made major contributions to the rapidly developing eld investigating the relationship between immunity and behavior. The book is divided into three parts. The rst part describes pathways by which the brain and immune systems communicate and int- act with each other. In the chapter “Cytokines and the Blood–Brain Barrier” p- vides insight into interactions between the blood–brain barrier and cytokines. Such interactions underlie basic communication between the immune system and brain that are present in normal as well as in disease conditions. In the chapter “Neu- chemical and Endocrine Responses to Immune Activation: The Role of Cytokines,” the neurochemical and endocrine consequences of immune challenge and cytokine administration on central neurotransmitter activity are discussed.
Download or read book Mechanisms of Neuroinflammation and Inflammatory Neurodegeneration in Acute Brain Injury written by Arthur Liesz and published by Frontiers Media SA. This book was released on 2015-11-13 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanisms of brain-immune interactions became a cutting-edge topic in systemic neurosciences over the past years. Acute lesions of the brain parenchyma, particularly, induce a profound and highly complex neuroinflammatory reaction with similar mechanistic properties between differing disease paradigms like ischemic stroke, intracerebral hemorrhage (ICH) and traumatic brain injury (TBI). Resident microglial cells sense tissue damage and initiate inflammation, activation of the endothelial brain-immune interface promotes recruitment of systemic immune cells to the brain and systemic humoral immune mediators (e.g. complements and cytokines) enter the brain through the damaged blood-brain barrier. These cellular and humoral constituents of the neuroinflammatory reaction to brain injury contribute substantially to secondary brain damage and neurodegeneration. Diverse inflammatory cascades such as pro-inflammatory cytokine secretion of invading leukocytes and direct cell-cell-contact cytotoxicity between lymphocytes and neurons have been demonstrated to mediate the inflammatory ‘collateral damage’ in models of acute brain injury. Besides mediating neuronal cell loss and degeneration, secondary inflammatory mechanisms also contribute to functional modulation of neurons and the impact of post-lesional neuroinflammation can even be detected on the behavioral level. The contribution of several specific immune cell subpopulations to the complex orchestration of secondary neuroinflammation has been revealed just recently. However, the differential vulnerability of specific neuronal cell types and the molecular mechanisms of inflammatory neurodegeneration are still elusive. Furthermore, we are only on the verge of characterizing the control of long-term recovery and neuronal plasticity after brain damage by inflammatory pathways. Yet, a more detailed but also comprehensive understanding of the multifaceted interaction of these two supersystems is of direct translational relevance. Immunotherapeutic strategies currently shift to the center of translational research in acute CNS lesion since all clinical trials investigating direct neuroprotective therapies failed. To advance our knowledge on brain-immune communications after brain damage an interdisciplinary approach covered by cellular neuroscience as well as neuroimmunology, brain imaging and behavioral sciences is crucial to thoroughly depict the intricate mechanisms.

Download or read book Inflammation and the Microcirculation written by D. Neil Granger and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microcirculation is highly responsive to, and a vital participant in, the inflammatory response. All segments of the microvasculature (arterioles, capillaries, and venules) exhibit characteristic phenotypic changes during inflammation that appear to be directed toward enhancing the delivery of inflammatory cells to the injured/infected tissue, isolating the region from healthy tissue and the systemic circulation, and setting the stage for tissue repair and regeneration. The best characterized responses of the microcirculation to inflammation include impaired vasomotor function, reduced capillary perfusion, adhesion of leukocytes and platelets, activation of the coagulation cascade, and enhanced thrombosis, increased vascular permeability, and an increase in the rate of proliferation of blood and lymphatic vessels. A variety of cells that normally circulate in blood (leukocytes, platelets) or reside within the vessel wall (endothelial cells, pericytes) or in the perivascular space (mast cells, macrophages) are activated in response to inflammation. The activation products and chemical mediators released from these cells act through different well-characterized signaling pathways to induce the phenotypic changes in microvessel function that accompany inflammation. Drugs that target a specific microvascular response to inflammation, such as leukocyte-endothelial cell adhesion or angiogenesis, have shown promise in both the preclinical and clinical studies of inflammatory disease. Future research efforts in this area will likely identify new avenues for therapeutic intervention in inflammation.

Download or read book Inflammatory Signalling at the Blood brain Barrier written by Leon Smyth and published by . This book was released on 2018 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: The blood-brain barrier (BBB) is an important protective structure that restricts the free passage of blood components and circulating immune cells into the brain. The BBB is primarily composed of endothelial cells that line the inside of the vessel, and is surrounded by pericytes that perform critical roles in its formation and maintenance. In this project, I aimed to examine aspects of inflammatory signalling at the BBB using primary human brain pericytes and endothelia. Initially, pericytes were characterised in human brain tissue to develop a panel of markers for pericytes in vitro. Characterisation studies validated that in vitro cultures of pericytes recapitulated their in situ phenotype, as well as identifying two novel markers of vascular smooth muscle cell phenotype in situ and in vitro. A protocol for the isolation of primary human brain endothelia was then developed to study the interactions of pericytes and endothelia in vitro, and these cultures were shown to retain their unique brain endothelial phenotype. Using cultures of pericytes and endothelia, differences in the inflammatory response of these two cell types were identified, including unique secretions, and differential sensitivity to inflammatory stimuli. Subsequently, the role of platelet-derived growth factor-BB (PDGF-BB) was investigated in greater detail. PDGF-BB was found to cause a proliferative response in brain pericytes, as has been found previously, but also induced the expression of inflammation-related secretions. The pathways through which this inflammatory response was mediated were dissected using genetic and pharmacological inhibitors. Interestingly, it was found that PDGF-BB altered pericyteendothelial interactions, stopping pericytes from strengthening the endothelial barrier. The role of PDGF-BB was investigated further in co-cultures, incorporating astrocytes, microglia, endothelia, and pericytes. It was observed that PDGF-BB improves the formation of blood vessel-like endothelial cords in vitro due to reduced cell death and increased expression of angiogenesis-associated molecules, reminiscent of its effects in vivo. The BBB is a critical structure in the brain, but has not yet been targeted to treat disease. Together these findings provide novel insights into cell-cell signalling at the BBB, and how these interactions are modified during inflammatory conditions. Because BBB damage and neuroinflammation are critical disease processes in neurological diseases, the factors that govern neuroinflammation at the BBB present potential drug targets to prevent the progression of AD.
