This conference was held under the sponsorship of the Eastern Pennsylvania Branch of the American Society for Microbiology, as one in a continuing series of Basic Science Symposia. The untiring volunteer effects of the members of the Symposium Committee are deeply appreciated. The Bureau of Laboratories of the Pennsylvania Department of Health was a cosponsor and generously provided staff and secretarial services to handle the difficult task of registration. The Department of Microbiology and of Microbiology and Immunology at the five medical schools in Philadelphia -- Temple University School of Medicine, Medical College of Pennsylvania, Thomas Jefferson University, Hahnemann University and the University of Pennsylvania -- were academic cosponsors, and the support of the Chairpersons and the faculties are gratefully acknowledged.

Download Host Defenses to Intracellular Pathogens Book in PDF, ePub and Kindle
The subject matter of this volume was the basis for a confer ence held in Philadelphia in June, 1981, and is an important one in the contemporary area of how the host interacts with micro organisms. In conception, it grew out of a graduate course entitled, "The Infectious Process," which has been taught in the Department of Microbiology and Immunology at Temple University School of Medicine during the past twelve years. This course has explored the broad areas of mechanisms of microbial pathogenesis and host resistance by in-depth consideration of selected models of experimental infection and immunity, as well as the clinical literature. It is noteworthy that there is no adequate text for this material, as the subject matter naturally crosses a wide spectrum of traditional disciplinary lines, encompassing topics as diverse as the mechanisms of action of bacterial toxins, the role of complement and antibody in phagocytosis, and the importance of cross-reacting bacterial polysaccharide antigens in vaccine development. A major portion of the course has always considered "cellular immunity" as it applies to host defenses to intracellular pathogens. It is in this area that the necessity for amalgamation of information from different disciplines is most evident, for one must be intimately concerned with the interactions between the microbe and the phagocyte, both before and after specific immune recognition.

Download Biology of Growth Factors Book in PDF, ePub and Kindle
Growth factors are elaborated to control the growth of cells in such physiological processes as wound healing, tissue regeneration and the immune response. Abnormal production of these growth factors, their receptors or intracellular med!ators of their action may lead to disease states including oncogenesis. This volume will focus on exciting developments in defining the precise molecular lesions that permit the conversion of controlled proliferative signals to neoplasia, on the possible involvement of growth factors in the development of blood vessel diseases as seen in diabetes and atherosclerosis, on the altered immune surveillance that leads to autoimmunity and on the fundamental mechanisms by which growth factors signal their target cells. We expect that the contents of this volume will help promote understanding of the role of these fundamental biological processes and their alterations in a wide variety of disease states and stimulate new investi gations in this important area of biomedical research.

Download Immune Response Activation and Immunomodulation Book in PDF, ePub and Kindle
Immune Response Activation and Immunomodulation has been written to address the perceived needs of both medical school and undergraduate curricula and to take advantage of new understandings in immunology. We have tried to achieve several goals and present the most important principles governing the function of the immune system. Our fundamental objective has been to synthesize the key concepts from the vast amount of experimental data that have emerged in the rapidly advancing field of immunology. The choice of what is most important is based on what is most clearly established by experimentation, what our students find puzzling, and what explains the wonderful efficiency and economy of the immune system. Inevitably, however, such a choice will have an element of bias, and our bias is toward emphasizing the cellular interactions in immune response by limiting the description of many of the underlying biochemical and molecular mechanisms to the essential facts. This book gives an insight into the role of cytokines in activating immune response during pathogenic invasion. Immunomodulation, aryl hydrocarbons, the role of the protein defensin and nucleated cells in provoking immune response, Bcl protein/gene-based apoptotic pathways, and plant-derived phytochemical-mediated immune response are all central themes of this book.

Download Innate Immune Cell Recruitment and Host Defense in Response to Intracellular Bacterial Infection Book in PDF, ePub and Kindle
The interactions between invading pathogens and host immune cells that respond to infection is a long and involved relationship. In particular, a class of pathogens have evolved to not only evade clearance by the cells of the innate immune system, but do so by manipulation of the host cytosol. This proximity has led to the intricate co-evolution of clearance and evasion mechanisms of the host and pathogen, respectively. How these interactions are carried out in the cellular immune response is the subject of this dissertation. In Chapter 2, I build a localized infection model for one such pathogen, Listeria monocytogenes, using the transparent zebrafish larval host. Using this model, I demonstrate the functional presence of a conserved innate immune sensing pathway, the inflammasome, that surveils the cytosol for the presence of bacterial flagellin. Upon optimal inflammasome activation, the host is protected from lethal infection, and I show that macrophages are the crucial host cell population in this defense. In Chapter 3, I characterize L. monocytogenes' utilization of the host actin network demonstrating live imaging of this interaction for the first time in vivo. Once L. monocytogenes is localized within the cytosol, it slows down macrophage motility, although in an actin independent manner. In Chapter 4, I develop a model to study the recruitment and resolution of leukocytes during concurrent wounding and infection. This model demonstrates both beneficial and detrimental leukocyte responses, and provides evidence that the immune responses to bacterial infection and wounding are separable programs during early stages of immune response. Taken together, I have shown that macrophages are a crucial part of host defense downstream of inflammasome activation, that macrophages activate other cell autonomous responses during their interaction with intracellular pathogens, and that macrophage-neutrophil interactions can be critical in determining a beneficial or detrimental response to infection. These findings highlight the intricate and close evolution of host immune cells and intracellular pathogens, as well as the critical nature of inflammatory balance during immune responses.

Download Understanding and Exploiting Host-Commensal Interactions to Combat Pathogens Book in PDF, ePub and Kindle
Trillions of commensal microbes reside on and inside the human body, including the intestinal and respiratory tracts, which encompass various microbial taxa, such as bacteria, fungi, archea and viruses. The close proximity of microbes with the host provides an opportunity to continually interact with each other. Advances in research approaches, including high-throughput sequencing, have allowed us to study host and commensal microbes at the genetic and functional levels. Recent studies suggest that commensal microbes play a crucial role in the development of the host’s immune system and induce innate and adaptive immune responses against pathogens. It is also becoming apparent that the gut commensals are endowed with a capacity to alter immune responses in organs beyond the intestine, such as the lungs, highlighting the significance of the gut commensals in controlling systemic immunity. On the other hand, the host’s immune system possesses the ability to shape the repertoire of commensal microbes and contribute to the establishment of beneficial relationships with them. A better understanding of host-commensal interactions will be important for designing effective vaccines and therapeutics against pathogens. This Research Topic sheds light on our current understanding of the interplay between the host’s immune system and commensal microbes and how this interplay can be exploited for prophylactic and/or therapeutic strategies against pathogens.
