This book was released on 2018-01-11 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inflammation is a fundamental protective mechanism and at the same time the driving force of a variety of major diseases in humans. Indeed, acute self-resolving inflammation usually plays a positive role for the host, as exemplified by infectious diseases where its positive role is well established and testified by its perception as innate immunity. On the other hand, non-resolving inflammation and consequent chronicization is a key determinant of immunopathology and clinical manifestations of most major diseases in humans. As a consequence, it is increasing appreciated that the problem with inflammation is not how often it starts, but how often it fails to resolve. Appropriate resolution of inflammatory responses, which also drives activation of tissue damage repair mechanisms and return of local tissues to homeostasis, is a necessary process for ongoing health. Interestingly, cells sustaining these processes are also key to the proinflammatory responses, and the underlying “pro-resolving” molecular pathways are triggered as part of the pro-inflammatory response. This clearly indicates resolution of inflammation as an active process requiring functional repolarization of inflammatory cells that calls our attention on the underlying molecular mechanisms. The increasing number of anti-inflammatory drugs best-sellers in the pharma market is a clear indication of the relevance of having inflammation under check; nonetheless, there is still a great need for better acting pharmacological tools for the control of inflammation. Indeed, the remarkable success of biological drugs targeting proinflammatory cytokines has indicates that tools able to block proinflammatory mediators have promising applications, but at the same time has made clear that there are intrinsic limitations to this approach which frequently vanish undermine the activity of single targeting drugs, including the well-known redundancy of inflammatory mediators. Under self-limiting conditions inflammation spontaneously resolves in an active process. Some cellular and molecular mechanisms involved in inflammation resolution have been uncovered in the recent past, and include generation of specific cytokines, apoptosis of inflammatory leukocytes, lipid mediators, macrophage repolarization and others are likely to be revealed in the next future, since loss-of-function mutations of an increasing number of genes results in the development of spontaneous inflammation in experimental animals. We argue that “pushing for“ inflammation resolution by exploiting active naturally-occurring pro-resolving processes may have significant advantages over the attempt to simply “push back” inflammation by passive blockade of proinflammatory mediators. At present the research in the field of inflammation aims at identifying and validates new molecules involved in the resolution of inflammation as a basis for the development of innovative therapeutic strategies in chronic inflammatory and autoimmune diseases. This involves the discovery of new natural or synthetic “pro-resolving” molecules from plant and animals and the investigation of endogenous inflammation “pro-resolving” mechanisms, including atypical chemokine receptors, decoy receptors, and microRNA. An extensive effort is focused on the regulation by “pro-resolving” agents on two molecular systems of key relevance in inflammation: the chemokine system, which regulates recruitment, permanence and egress of leukocyte in tissues; and the Toll Like Receptor (TLR)/IL-1R system, which is central for the activation of infiltrating leukocytes.
Download or read book Chemokine Biology Basic Research and Clinical Application written by Bernhard Moser and published by Springer Science & Business Media. This book was released on 2006-03-16 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemokines play an important role in recruiting inflammatory cells into tissues in response to infection and inflammation. They also play an important role in coordinating the movement of T-cells, B-cells and dentritic cells, necessary to generate an immune response (response to injury, allergens, antigens, invading microorganisms). They selectively attract leukocytes to inflammatory foci, inducing both cell migration and activation. They are involved in various diseases, like atherosclerosis, lung and skin inflammation, multiple sclerosis, or HIV. Volume 1 of this two-volume set discusses the immunobiology of chemokines. It is divided into two parts: a) cellular targets in innate and adaptive immunity, and b) effector cell traffic-unrelated functions. Together with volume 2, which discusses the pathophysiology of chemokines, both volumes give a comprehensive overview of chemokine biology.
Download or read book Fundamentals of Inflammation written by Charles N. Serhan and published by Cambridge University Press. This book was released on 2010-04-26 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: The acute inflammatory response is the body's first system of alarm signals that are directed toward containment and elimination of microbial invaders. Uncontrolled inflammation has emerged as a pathophysiologic basis for many widely occurring diseases in the general population that were not initially known to be linked to the inflammatory response, including cardiovascular disease, asthma, arthritis, and cancer. To better manage treatment, diagnosis, and prevention of these wide-ranging diseases, multidisciplinary research efforts are underway in both academic and industry settings. This book provides an introduction to the cell types, chemical mediators, and general mechanisms of the host's first response to invasion. World-class experts from institutions around the world have written chapters for this introductory text. The text is presented as an introductory springboard for graduate students, medical scientists, and researchers from other disciplines wishing to gain an appreciation and working knowledge of current cellular and molecular mechanisms fundamental to inflammation.

Available in PDF, EPUB and Kindle. Book excerpt: A hallmark of inflammation is the accumulation of leukocytes, which can serve to remove pathogens and necrotic tissue, but may also damage healthy tissue and exacerbate the inflammatory response. Our understanding of leukocyte recruitment in inflammation was revolutionized in the late 1980s by the discovery of chemokines (chemotactic cytokines), a family of small, secreted proteins that induce migration of selective subsets of leukocytes. Shortly afterwards, chemokines were found to exert their functions through the now familiar chemokine receptors, members of the G protein-coupled receptor superfamily. As their physiological and pathological functions were elucidated, chemokine receptors have become popular targets for drug development in inflammatory diseases as well as cancer metastasis and HIV infection. Extensive research has revealed that the functions of chemokines and their receptors are regulated at numerous levels, including: genetic mutations/polymorphisms; control of expression levels; ligand internalization via functional or decoy receptors; intrinsic selectivity of chemokine-receptor binding; hetero- or homo-oligomerization of chemokines or of receptors; alternative signalling pathways; interaction of chemokines with glycosaminoglycans; post-translational modifications; and binding to pathogen-derived inhibitors. This Special Issue of IJMS focused on the natural and pharmacological mechanisms by which the activities of chemokines and their receptors can be regulated.

This book was released on 2008-02-02 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemokines and their receptors play a central role in the pathogenesis of numerous, perhaps all, acute and chronic inflammatory diseases. About 50 distinct chemokines produced by a variety cell types and tissues either c- stitutively or in response to inflammatory stimuli are involved in a plethora of biological processes. These small secreted proteins exert their exquisitely variegated functions upon binding to a family of seven-transmembrane spanning G-protein coupled receptors (GPCRs) composed of almost 20 distinct entities. The biological activities of chemokines range from the control of leukocyte trafficking in basal and inflammatory conditions to the regulation of hema- poiesis, angiogenesis, tissue architecture, and organogenesis. The basis for such diversified activities rests, on one hand, upon the ubiquitous nature of chemokine production and chemokine receptor expression. Virtually every cell type can produce chemokines and expresses a unique combination of chemokine receptors. On the other hand, chemokine receptors make use of a flexible and complex network of intracellular signaling machineries that can regulate a variety of cellular functions ranging from cell migration, growth, and differentiation to death. As knowledge of the size of chemokine and chemokine receptor families rapidly reaches completeness, much is still to be uncovered in terms of fu- tional architecture of the chemokine system. The disparity between the large number of chemokines and that smaller number of receptors is balanced by the promiscuity in ligand–receptor interactions, with multiple chemokines binding to the same receptor and several chemokines binding to more than one receptor.

Available in PDF, EPUB and Kindle. Book excerpt: Since the introduction of microscopy, pathologists have noted tumor infiltration by inflammatory cells and presumed that this represents the host's attempt to reject its tumor. Recent advances in the molecular biology of inflammation have revealed the signals involved in attracting inflammatory cells to tumors and, for the most part, these signals are mediated by chemokines and their receptors. Chemokines are low molecular weight proteins that attract and activate specific subsets of leukocytes to the exclusion of others.

This book was released on 2012-12-06 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, cytokine research has emerged as one of the most exciting and critical fields for providing fundamental knowledge of normal and abnormal human development. Today, it is apparent that cytokines orchestrate growth from the early embryonic stage to maturity and are responsible for the normal function of virtually every organ system. Furthermore, virtually all disease states have been associated, at least in part, with cytokine aberrations. In this volume, the editors have brought together internationally known experts in the field of interleukin research to provide a comprehensive review of the biology of the interleukins and their role in both health and illness, while maintaining a balance between the basic science and clinical aspects. Cytokines: Interleukins and their Receptors should be of interest to a wide variety of researchers including clinical hematologists, oncologists, immunologists, in addition to medical and PhD students and researchers with an interest in cytokines.

Download or read book Chemokines and Chemokine Receptors in Brain Homeostasis written by Flavia Trettel and published by Frontiers Media SA. This book was released on 2015-08-17 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virtually involved in all pathologies that present an inflammatory component, it is now evident that, in the central nervous system, chemokines and chemokine receptors possess pleiotropic properties beyond chemotaxis: costitutive brain expression of chemokines and their receptors on endothelial cells, but also on neurons and glia, suggests a role for such molecules in mediating homeostatic cross-talk between cells of the brain perenchyma. Cross-talk between neurons and glia is determinant to the establishment and maintenance of a brain enviroment that ensure normal function, and in particular glial cells are active players that respond to enviromental changes and act for the survival, growth, differentiation and repair of the nervous tissue: in this regard brain endogenous chemokines represent key molecules that play a role in brain development, neurogenesis, neurotransmission and neuroprotection. As important regulators of peripheral immune response, chemokines are molecules of the immune system that play a central role in coordinating communication between the nervous and the immune systems, in the context of infections and brain injury. Indeed, in phatological processes resulting from infections, brain trauma, ischemia and chronic neurodegenerative diseases, chemokines represent important neuroinflammatory mediators that drive leucocytes trafficking into the central nervous system, facilitating an immune response by targeting cells of the innate and adaptive immune system. The third edition of the international conference "Chemokines and Chemokine Receptors in the Nervous System", hold in Rome in October 2013, represented an exciting platform to promote discussion among researchers in different disciplines to understand the role of chemokines in brain homoestasis. This Frontiers Research Topic arises from this conference, and wants to be an opportunity to further discuss and highlight the importance of brain chemokines as key molecules that, not only grant the interplay between the immune and the nervous systems, but in addition drive modulatory functions on brain homeoastasis orchestrating neurons, microglia, and astrocytes communication.
Download or read book The Neutrophil written by Marco A. Cassatella and published by Karger Medical and Scientific Publishers. This book was released on 2003-01-01 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past, neutrophils were often reduced to their ability to release preformed mediators and kill pathogens. The present volume of Chemical Immunology and Allergy, however, offers a very broad and timely view by highlighting the versatile functions of neutrophils in inflammatory, immune and antitumoral responses. Leading investigators uncover novel aspects of neutrophils, such as their capacity to control gene expression at the transcriptional level, or respond to proinflammatory cytokines, cytokine receptor chains (gc) and endogenous anti-inflammatory lipid mediators. Further points under discussion are neutrophils presenting antigens, activating T cells, participating in chemokine networking, and producing IL-12 and other cytokines during infectious diseases. Among the most original findings presented in this publication figure the observations that neutrophils cause increased vascular permeability during acute inflammation, regulate directly the angiogenic process, and influence tumor development. A final article offers a detailed description of the molecular processes affecting neutrophil cell death and survival. Unique in its field, this valuable volume is recommended reading not only for immunologists and pathologists, but also for cell biologists, hematologists and immunobiologists.

Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews the current research in Chemokine Receptors and their role in physiological processes in the body, as well as their role in different pathological conditions. Chemokine Receptors are important for the migration of different types of cells, including immune cells to lymphoid organs and non-lymphoid organs thanks to the interaction with chemokines. The presence of different chemokine receptors on the cells' surface was studied in normal states and diseases, some of them correlating with migration of subsets that play pro-disease roles or other help controlling the condition. Currently, state-of-the-art technology is helping researchers to better identify gene and protein expression of chemokine receptors at the single cell level. This large new data reveals the complexity of co-expression of various markers in the same cells and as well among different types of cells. Moreover, chemokine receptors are also helpful to identify different stages among subsets, and their correlation with better or worst responses in disease. Finally, treatments designed to inhibit or to block chemokine receptors are designed and tested at the preclinical and clinical level with different results. Here, we focus on the main chemokine receptors described in the current literature that play a role in health and diseases such as infections, autoimmune disorders, and cancer. - Chemokine receptors in the era of single cell gene and protein analysis - Chemokine receptor's role in COVID-19 - Update in the role of chemokine receptors in health and disease
