Fungi are found in virtually every environment, and comprise a significant portion of the normal microflora of healthy individuals. Some species of fungi are aeroallergen sources capable of inducing sensitization and causing exacerbation of asthma and respiratory allergy. Others are transmissible between hosts and may cause no symptoms in healthy individuals. However, immune suppressed individuals may develop invasive disease marked by tissue invasion with a potential for widespread dissemination. Existing therapies for patients consist of antifungal drugs, yet these require prolonged administration with the possibility of adverse side effects, and may be rendered ineffective by the emergenc...
Fungal infections represent nowadays a significant burden on the healthcare system of most of the countries, and are among the infections with the highest mortality rates. This has fostered the study of the interaction of these organisms with the human host. The outer most layer of a fungal cell is the cell wall, and together with the secreted components into the extracellular compartment, are the first lines of contact with the host cells. This interaction is critical for tissue adhesion, colonization and damage. In addition, these fungal extracellular components will define the outcome of the interaction with the host immune cells, leading either to the establishment of a protective antifu...
The protection mode of most available vaccines is based on antibody responses. Since efficient immune responses to many pathogens rely on activating all arms of the immune system, traditional vaccine development does not provide efficient protection against many diseases. Novel vaccination strategies need to allow presentation of antigens that activate the full array of the immune response in the right composition and should prevent pathogen entry by mobilizing the mucosal immune response. New technological advances optimize the immunogenicity of 'live' and sub-unit vaccines. This book offers an interdisciplinary overview on research and future strategies for rational vaccine design based on recent developments in molecular biology and immunology. It covers new aspects of the immunological interplay between prokaryotic and eukaryotic systems as well as achievements in the development of novel vaccine candidates. Chapters on edible vaccines, on vaccines against bioterror agents and on economical and safety aspects of novel vaccine development round off this title.
Recent advances in the understanding of microbiota in health and diseases are presented in this special issue of Frontiers in Immunology and Frontiers in Microbiology as well as their impact on the immune system that can lead to the development of pathologies. Potential perspectives and biomarkers are also addressed. We offer this Research Topic involving 64 articles and 501 authors to discuss recent advances regarding: 1. An overview of the human microbiota and its capacity to interact with the human immune system and metabolic processes, 2. New developments in understanding the immune system’s strategies to respond to infections and escape strategies used by pathogens to counteract such responses, 3. The link between the microbiota and pathology in terms of autoimmunity, allergy, cancers and other diseases.
Offers the latest insights into the fundamental biology and pathogenesis of A. fumigatus. Provides a combined synopsis of both A. fumigatus and its diseases and therapies. Encompasses the most up-to-date knowledge to serve as a resource guide for the next decade of study on this organism and the many diseases it causes. Covers the fundamental biology of A. fumigatus including specific features in genetics, biochemistry, and cell biology that can explain the virulence of this opportunistic pathogen. Discusses the wide range of clinical infection, plus the latest diagnostic and treatment strategies, in specific patient populations.
A comprehensive review of all known immune mechanisms for medically important fungal pathogens from the organ perspectives of the human body. This authoritative guide is organized by organ system, as one particular fungus can have several different effects.
