Immunosuppression involves an act that reduces the activation or efficacy of the immune system. Some portions of the immune system itself have immuno-suppressive effects on other parts of the immune system, and immunosuppression may occur as an adverse reaction to treatment of other conditions. Deliberately induced immunosuppression is generally done to prevent the body from rejecting an organ transplant, treating graft-versus-host disease after a bone marrow transplant, or for the treatment of auto-immune diseases such as rheumatoid arthritis or Crohn's disease. This is typically done using drugs, but may involve surgery (splenectomy), plasmapharesis, or radiation. A person who is undergoing immunosuppression, or whose immune system is weak for other reasons (for example, chemotherapy and HIV patients) is said to be immunocompromised. When an organ is transplanted, the immune system of the recipient will most likely recognise it as foreign tissue and attack it. The destruction of the organ will, if untreated, end in the death of the recipient. In the past, radiation therapy was used to decrease the strength of the immune system, but now immunosuppressant drugs are used to inhibit the reaction of the immune system. The downside is that with such a deactivated immune system, the body is very vulnerable to opportunistic infections, even those usually considered harmless. Also, prolonged use of immunosuppressants increases the risk of cancer. This book presents the latest research in the field.

With the interest in biomarkers available for diagnostic, therapeutic, prognostic and research applications growing rapidly, it is now expected that every pathologist should be aware of the correct application of immunohistochemistry in daily practice. This fully updated fourth edition provides practical guidance about preparation, key uses and pitfalls of antibodies for immunohistology in a unique A-Z format. Seventeen full colour infographics present detail about specific biomarkers, including FOXL2, GATA3 and SOX10, pulling out information about expression in tissues and prognosis. Expanded with new biomarkers and the removal of biomarkers that are no longer in common use, each entry in this concise new edition follows a standard structure for quick and easy access by busy readers.

Parasites and infectious diseases are everywhere and represent some of the most potent forces shaping the natural world. They affect almost every aspect imaginable in the life of their hosts, even as far as the structure of entire ecosystems. Hosts, in turn, have evolved complex defences, with immune systems being among the most sophisticated processes known in nature. In response, parasites have again found ways to manipulate and exploit their hosts. Ever since life began, hosts and parasites have taken part in this relentless co-evolutionary struggle with far-reaching consequences for us all. Today, concepts borrowed from evolution, ecology, parasitology, and immunology have formed a new synthesis for the study of host-parasite interactions. Evolutionary parasitology builds on these established fields of scientific enquiry but also includes some of the most successful inter-disciplinary areas of modern biology such as evolutionary epidemiology and ecological immunology. The first edition of this innovative text quickly became the standard reference text for this new discipline. Since then, the field has progressed rapidly and an update is now required. This new edition has been thoroughly revised to provide a state-of-the-art overview, from the molecular bases to adaptive strategies and their ecological and evolutionary consequences. It includes completely new material on topics such as microbiota, evolutionary genomics, phylodynamics, within-host evolution, epidemiology, disease spaces, and emergent diseases. Evolutionary Parasitology is suitable for advanced undergraduates, graduate level students, and interdisciplinary researchers from a variety of fields including immunology, genetics, sexual selection, population ecology, behavioural ecology, epidemiology, and evolutionary biology. Those studying and working in adjacent fields such as conservation biology, virology, medicine, and public health will also find it an invaluable resource for connecting to the bases of their science.

Intended for specialists in B cell immunology, this is an investigation of such topics as the movement of a monoclonal antibody from the laboratory into the clinic, the field of Fc receptors, the impact of monoclonal antibodies on the diagnosis and treatment of human cancer, and detailed analyses of specific antibody systems: mouse lambda and human kappa. Antibodies have always been vital to any major progress within immunology. From diagnostic tools to vehicles for modern therapy against cancer, infections, and autoimmune diseases, antibodies serve many purposes, yet our knowledge of them, their properties and structural characteristics is incomplete. "The Antibodies" series seeks to provide the scientific community with a platform for a comprehensive review of topics of contemporary interest for specialists in this area.

This book examines the latest research developments in the study of the production, types and roles in disease of granulocytes. Topics include the regulation of granulocyte differentiation by microRNA and transcription factors; chemotactic assay of human neutrophils and eosinophils; basophilic granulocytes; and the role of granulocytes on the onset of tissue-destructive diseases.

This book examines the latest research developments in the field of basophil granulocytes, sometimes referred to as basophils, which are the least common of the granulocytes, representing about 0.01% to 0.3% of circulating white blood cells. The name comes from the fact that these leucocytes are basophilic, i.e., they are susceptible to staining by base dyes, as shown in the picture. Basophils contain large cytoplasmic granules which obscure the cell nucleus under the microscope. However, when unstained, the nucleus is visible and it usually has 2 lobes. The mast cell, a cell in tissues, has many similar characteristics.

In recent decades immunology has been one of the most exciting--and successful--fields of biomedical research. Over the past thirty years immunologists have acquired a detailed understanding of the immune system's unique recognition mechanism and of the cellular and chemical means used to destroy or neutralize invading organisms. This understanding has been formulated in terms of the clonal selection theory, the dominant explanation of immune behavior. That story is the subject of "The Generation of Diversity,"

A major problem for immunologists had long been to determine how cells of the immune system could produce millions of distinct antibodies--and produce them on demand. The clonal selection theory explains that cells with genetic instructions to produce each antibody exist in the body in small numbers until exposure to the right molecule--the antigen--triggers the selective cloning that will reproduce exactly the cell needed. But how can so many different antibody-producing cells be generated from such limited genetic material? The solution to this question came from new applications of molecular biology, and, as the authors argue, the impact of the new techniques changed both the methods and the concepts of immunology.

"The Generation of Diversity" is an intellectual history of the major theoretical problem in immunology and its resolution in the post-World War II period. It will provide for immunologists essential background for understanding the conceptual conflicts occurring in the field today.

Monoclonal antibodies have had their impact on biomedical research for more than a decade. Beside their exuberant use as reagents, quite a number of diagnostic and therapeutic approaches have been followed and an impressive number of technological improvements, e.g., humanization, recombinant miniantibodies, have been elaborated to strengthen the principle. With respect to clinical applications, the first generation of antibody 'drugs' is yielding promising results while second and third generation antibody constructs are already underway. The book reviews the status of technological development and brings this into the perspective of clinical results. A rapidly growing amount of clinical data is collected in an expanding number of indications. Hence, the review of clinical study results has been grouped according to the fields of oncology and of chronic and acute inflammation. This book will be of interest to scientists working in the fields of oncology, immunology, internal medicine and clinical chemistry.

This book presents a wide variety of immuno-gold techniques for use in virus diagnosis and research. Protocols are presented for state-of-the-art techniques, including in situ hybridization, freeze substitution, and the utilization of ultra-small probes and replicas for use by virologists and electron microscopists identifying and studying viruses, their components, and replication in cells. The procedures are described by eminent scientists and are pertinent to both experienced researchers and newcomers to this field who are interested in the localization of low antigenic mass structures.

A comprehensive guide to general strategies and specific methods for testing the immunotoxicity of chemicals in animal models and humans. Addressed to those seeking a basic introduction to the field as well as specialist researchers the book takes its focus from growing concern in scientific and public communities about the capacity of environmental agents to disrupt normal immune functions and thus increase susceptibility to tumours and infectious diseases. Compounds known to adversely affect the immune system are numerous and include drugs pesticides solvents halogenated and aromatic hydrocarbons and metals. The book draws on considerable recent progress in understanding the immunological consequences of chemical insults as well as increasingly sophisticated methodologies for assessing such effects. Close to 1000 references are included in this authoritative guide. The book opens with a detailed basic introduction to immunotoxicology. An extensive explanation of the function histophysiology and pathophysiology of the immune system emphasizes features that can aid the understanding and interpretation of the pathological changes caused by immunotoxic insults. Chapter two on the health impact of selected immunotoxic agents gives illustrative examples for some 30 chemicals that have been shown to exert immunotoxic effects in laboratory animals and for an additional seven groups of chemicals known to disturb immune functions in humans. For each brief discussions illustrate the chemical's distinct immunosuppressive properties and the mechanisms by which it exerts its toxic effects on the immune system. Chapter three provides detailed descriptions of a number of tests used in a tiered approach to the assessment of immunotoxicity. Against this background specific nonfunctional and functional tests for the assessment of immunotoxicology in experimental animals are presented and explained in full detail. Information on individual tests includes an explanation of why the test is important the types of data it can yield and exactly how it should be performed. Also included are sections offering advice on assessments in non-rodent species "in vitro "approaches and approaches using biomarkers in epidemiological studies and monitoring. The chapter concludes with a discussion of good laboratory practices for immunotoxicology studies and procedures for the validation of tests. Chapter five explains the much more complicated procedures needed to assess immunotoxicity in humans. An explanation of general questions to be considered when designing epidemiological studies is followed by presentation of three recommended testing schemes proposed by WHO and other agencies for preliminary evaluation of individuals exposed to immunotoxicants. Specific assays for assessing immune status are also described. The final chapter outlines a step-by-step process of risk assessment specific to the evaluation of potentially immunotoxic chemicals.
