Book Description
Pathogen infections are recognized by the immune system, which consists of two types of responses: an innate immune response and an antigen-specific adaptive immune response. The innate response is characterized by being the first line of defense that occurs rapidly in which leukocytes such as neutrophils, monocytes, macrophages, eosinophils, mast cells, dendritic cells, et cetera, are involved. These cells recognize the pathogen-associated molecular patterns (PAMPs), which have been evolutionarily conserved by the diversity of microorganisms that infect humans. Recognition of these pathogen-associated molecular patterns occurs through pattern recognition receptors such as Toll-like receptors and some other intracellular receptors such as nucleotide oligomerization domain (NOD), with the aim of amplifying the inflammation and activating the adaptive cellular immune response, through the antigenic presentation. In the present chapter, we will review the importance of the main components involved in the innate immune response, such as different cell types, inflammatory response, soluble immune mediators and effector mechanisms exerted by the immune response against bacteria, viruses, fungi, and parasites; all with the purpose of eliminating them and eradicating the infection of the host.

Book Description
In recent years increased scientific attention has been given to immediate defense mechanisms based on non-clonal recognition of microbial components. These mechanisms constitute the innate immunity arm of the body s defense. Identification of pathogens by these mechanisms involves primarily receptors recognizing sugar moieties of various microorganisms. Innate immunity based mechanisms are essential for the existence of multicellular organisms. They are evolutionarily conserved and designed to provide immediate protection against microbial pathogens to eradicate infection. Activation of innate immunity is crucial for transition to specific immunity and for its orientation, and to assist the specific immune response in the recognition of pathogens and their destruction. Innate immunity is regularly involved in the arrest of bacterial, mycotic, viral and parasitic infections, giving the specific immune response time to become effective. It becomes critically essential in immunocompromised patients who fail to mount specific immune responses due to congenital or acquired immunodeficiencies as a result of chemotherapy, dialysis, immunosuppressive drugs, or HIV infection. The Innate Immunity arsenal constitutes polymorphonuclear and mononuclear phagocytes, mast cells, the complement system, Natural Killer cells, antimicrobial peptides, and presumably a subset of T lymphocytes with TCRl receptors.

Book Description
Our understanding of the complex innate immune response is increasing rapidly. Its role in the protection against viral or bacterial pathogens is essential for the survival of an organism. However, it is equally important to avoid unregulated inflammation because innate immune responses can cause or promote chronic autoinflammatory diseases such as gout, atherosclerosis, type 2 diabetes or certain aspects of the metabolic syndrome. In this book leading international experts in the field of innate immunity share their findings, define the state of the art in this field and evaluate how insight into the molecular basis of these diseases could help in the design of new therapies. A tremendous amount of work on the innate immune response has been done over the last fifteen years, culminating in the 2011 Nobel Prize in Physiology/Medicine awarded for the discoveries of Toll genes in immunity in flies, membrane-bound Toll-like receptors in mammals, and dendritic cells as initiators of adaptive immunity.

Book Description
Mounting evidence in the past decade indicates that innate immunity mediates functions above and beyond first-line defense against infection. It is now appreciated that innate immune mechanisms are critically involved in the development of adaptive immunity and, moreover, the regulation of diverse physiological and homeostatic processes. The latter explains why deregulation of innate immunity may lead to pathological disorders that are not necessarily or directly related to host defense. This Volume compiles the latest advances in this rapidly evolving field as presented by eminent scientists at the 7th International Aegean Conference on Innate Immunity in Rhodes, Greece. It includes topics related to the biology and function of Toll-like and other pattern-recognition receptors, complement and its crosstalk with other physiological systems, inflammatory mechanisms and diseases, natural killer cells, and the cooperative interplay between innate and adaptive immune cells. This book is an excellent source of information for researchers and clinicians with interests in immunology, host-microbe interactions, and infectious and inflammatory diseases.

Book Description
Parasitic infections remain a significant cause of morbidity and mortality in the world today. Often endemic in developing countries many parasitic diseases are neglected in terms of research funding and much remains to be understood about parasites and the interactions they have with the immune system. This book examines current knowledge about immune responses to parasitic infections affecting humans, including interactions that occur during co-infections, and how immune responses may be manipulated to develop therapeutic interventions against parasitic infection. For easy reference, the most commonly studied parasites are examined in individual chapters written by investigators at the forefront of their field. An overview of the immune system, as well as introductions to protozoan and helminth parasites, is included to guide background reading. A historical perspective of the field of immunoparasitology acknowledges the contributions of investigators who have been instrumental in developing this field of research.

Book Description
The last decade has witnessed the delineation of innate immunity - a new area which has revolutionized our understanding of host-parasite interactions and their impact on defense mechanisms in infectious and noninfectious diseases. This volume of the book series 'Contributions to Microbiology' provides an update of the current knowledge of this expanding field of research and highlights some of its most important aspects. In eleven state-of-the-art articles, eminent international experts in the field address topics such as the innate immune system in mammals and insects, microbial protein ligands, antimicrobial peptides, complement, antibacterial chemokines, the role of neutrophils and monocytes, oxidative innate immune defenses and the effect of aging on innate immunity. The book will be a valuable resource for microbiologists, immunologists, students, scientists of other related disciplines, and clinicians with an interest in infectious or immunological diseases.

Book Description
Immunologists today are interested in all of the diverse cell-types involved in host defense and have a deeper appreciation of the importance of innate immune mechanisms as a first line of protection against pathogens. This volume thus discusses the isolation and functional characterization of cells involved in innate immunity in mouse and man, including mast cells and eosinophils. Other focuses include natural killer cells, methods in statistics, in vivo imaging, genome engineering, and mutagenesis and culture that are adapted to the study of innate immunity in these hosts. These are complemented with a series of chapters dealing with alternative models: plants, worms, mosquitoes, flies, and fish. Together, these approaches and models are being used to dissect the complex interplay between hosts and pathogens and contribute to developing strategies to help fight infection. With chapters written by experts on the cutting-edge of this technology, Innate Immunity is an essential reference for immunologists, histologists, geneticists, and molecular biologists.
