Download or read book Functions of Neutrophils During Respiratory Coronavirus Infection of Rats written by Joanna Rzepka and published by . This book was released on 2012 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pathogenesis of lower respiratory tract infections (LRI) is often associated with dysregulated and exacerbated immune response. Immune response to LRI is often triggered by virus-infected target cells, such as epithelial cells that line the respiratory tract. It is critical to understand how the epithelium regulates immediate immune responses to be able to manipulate these responses for host's benefits. Animal models are often used to examine immunopathogenesis associated with diseases. Rat coronavirus (RCoV) is a natural pathogen of rats, used as a model for studying respiratory tract diseases caused by coronaviruses. This dissertation aims to clarify the role of the alveolar epithelium in mediating neutrophil responses to RCoV-infection and examines the role of neutrophils in a timely virus clearance and induction of lung tissue damage. Infection of rats with RCoV resulted in prompt recruitment of increased numbers of neutrophils to the lungs of infected animals. The peak of neutrophil recruitment coincided with observable, transient lung tissue injury, which was resolved soon after neutrophil counts in the lung had dropped to the homeostasis level. Interestingly, only in the presence of neutrophils infectious RCoV was effectively cleared from the lungs within 8 days after exposure of the animal to the virus. Depletion of neutrophils before the infection caused increased morbidity and mortality, without causing lung tissue damage. The second and the third chapters of this dissertation aim to clarify the role of alveolar epithelial cells, infected with RCoV, in mediation of neutrophil chemotaxis and inhibition of their apoptosis. Infection of type I alveolar epithelial cells, cultured in vitro, was performed to characterize signaling molecules involved in chemotaxis of neutrophils during RCoV infection and inhibition of their apoptosis. Epithelium-produced CXC chemokines, signaling through CXCR2 receptor on the surface of neutrophils, directed the recruitment of neutrophils and prolonged their life span. The presence of infectious virus particles was not required to elicit these effects. Understanding how the interactions between infected alveolar epithelial cells and the innate immune system, in particular neutrophils, are stimulated during infection with respiratory coronaviruses, will help in designing effective therapeutic strategies for pulmonary viral infections.
Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Download or read book Oxidative Stress and Biomaterials written by Thomas Dziubla and published by Academic Press. This book was released on 2016-05-31 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidative Stress and Biomaterials provides readers with the latest information on biomaterials and the oxidative stress that can pose an especially troubling challenge to their biocompatibility, especially given the fact that, at the cellular level, the tissue environment is a harsh landscape of precipitating proteins, infiltrating leukocytes, released oxidants, and fluctuations of pH which, even with the slightest shift in stasis, can induce a perpetual state of chronic inflammation. No material is 100% non-inflammatory, non-toxic, non-teratogenic, non-carcinogenic, non-thrombogenic, and non-immunogenic in all biological settings and situations. In this embattled terrain, the most we can hope for from the biomaterials we design is a type of “meso-compatibility, a material which can remain functional and benign for as long as required without succumbing to this cellular onslaught and inducing a local inflammatory reaction. Explores the challenges of designing and using biomaterials in order to minimize oxidative stress, reducing patterns of chronic inflammation and cell death Brings together the two fields of biomaterials and the biology of oxidative stress Provides approaches for the design of biomaterials with improved biocompatibility

Download or read book Immunobiotics Interactions of Beneficial Microbes with the Immune System written by Julio Villena and published by Frontiers Media SA. This book was released on 2018-01-26 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term “immunobiotics” has been proposed to define microbial strains able to beneficially regulate the mucosal immune system. Research in immunobiotics has significantly evolved as researchers employed cutting-edge technologies to investigate the complex interactions of these beneficial microorganisms with the immune system. During the last decade, our understanding of immunobiotics-host interaction was profoundly transformed by the discovery of microbial molecules and host receptors involved in the modulation of gut associated immune system, as well as the systemic and distant mucosal immune systems. In recent years, there has been a substantial increase in the number of reports describing the beneficial effects of immunobiotics in diseases such as intestinal and respiratory infections, allergy, inflammatory bowel disease, obesity, immunosuppression, and several other immune-mediated conditions. Evidence is also emerging of immunobiotics related molecules with immunomodulatory functions leading to the production of pharmabiotics, which may positively influence human or animal health. Therefore, research in immunobiotics continue to contribute not only to food but also medical and pharmaceutical fields. The compilation of research articles included in this ebook should help reader to have an overview of the recent advances in immunobiotics.

Download or read book Cytokine Storm Syndrome written by Randy Q. Cron and published by Springer Nature. This book was released on 2019-09-09 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cytokine Storm Syndromes, including HLH and MAS, are frequently fatal disorders, particularly if not recognized early and treated during presentation. The genetics of Cytokine Storm Syndromes are being defined with many of the risk alleles giving rise to mutations in the perforin-mediated cytolytic pathway used by CD8 cytotoxic T cells and natural killer cells. These are being studied using murine models. Up to 10% of the general population may carry risk alleles for developing Cytokine Storm Syndromes, and Cytokine Storm Syndromes are being increasingly recognized around the world in pediatric and adult hospitals. A variety of infectious, rheumatic, and oncologic triggers are commonly associated with Cytokine Storm Syndromes, but understanding this disorder is critical for all researchers and physicians to ensure timely and appropriate therapy. This textbook, the first of its kind, addresses all aspects of the disorder – from genetics, pathophysiology, and ongoing research, to clinical presentations, risk factors, and treatment.
