Activation of the complement system gives rise to a number of molecular species which can interact with host-derived cells and regulate their function. This interaction is mediated through distinct cell surface complement receptors, and receptor engagement produces biologic responses which can either modulate host defense reactions or enhance inflammation. Although the first complement receptor was recognized more than 30 years ago [80J, detailed biochemical information concerning the receptors has only recently become available. Currently, eight distinct complement receptors are recognized. Five receptors (CRl, CR2, CR3, C3a receptor, and C3e receptor) react with various regions on C3 while the other receptors display specificity for Clq, C5a, or Factor H. This chapter focusses on the chemistry of the various ligands and receptors and discusses the biologic activities which arise as a result of receptor-ligand interaction. II. CIQ Receptor A. The Ligand Clq is the recognition molecule of the classical complement pathway [reviewed in 20, 130]. In serum, it is part of a calcium-dependent penta molecular complex containing one molecule ofClq and two molecules each of the pro enzymes Clr and CIs. During classical pathway activation, the macromolecular complex becomes associated with the activator through the Clq subcomponent. Bound Clq undergoes a conformational change and induces the proteolytic autoactivation of Clr which in turn effects the proteolytic activation of CIs. This process is controlled by the Cl inhibitor (ClINH) which binds irreversibly to activated Clr and CIs, and inhibits their enzymatic activities.

Peter A. Miescher The skin has always been one of the major targets to clinicians interested in immunology. Initially, the main focus was centred on allergic conditions such as contact hypersensitivity and urticeria. Gradually, the spectrum of immunological conditions involving the skin increased, encompassing diseases such as Dermatitis Herpetiformis, Erythema Muitiforme, Cutaneous Bullous Disorders and Photo toxic Reactions. It has been the intention of the editors of Springer Seminars in Immu nopathology to cover the broad spectrum of immune phenomena encountered in dermatological diseases with special emphasis to newer developments in Immunopathology. Dr. 1. N. Gigli has managed to assemble a series of important contributions within two issues of the Journal which are of such an interest to dermatologists that we decided to publish this topic as a separate volume for all dermatologists who do not have access to Seminars in Immunopathology. 3 Immunologically Mediated Epidermal Cell Injury Richard D. Sontheimer* and James N. Gilliam Division of Dermatology, University of Texas Health Science Center, 5323 Harry Hines Boulevard, Dallas, Texas 75235, USA Introduction The epidermis is a functional unit of different cell types that has the critical role of protecting man from his environment. The three major cell types that make up the epidermis (keratinocytes, melanocytes, and Langerhans cells) serve different protective functions. The vast majority of epidermal cells are keratinocytes (Fig. 1)."

Howard C. Thomas In normal subjects the regulatory apparatus of the immune system permits responses to foreign antigens but suppresses those directed to "self' components. Autoimmune disease occurs as a failure ofthis system either as a result of a primary defect in the regulatory apparatus (primary autoimmunization) or because of a change in the antigenicity of the tissues (secondary autoimmunization). Autoaggressive reactions are characterised by the presence of autoantibodies. When these are directed to membrane displayed antigens (Fig. 1) they are probably of importance in the lysis of hepatocytes. Those directed to cytoplasmic antigens may be useful diagnostically but are of unknown pathogenic significance. When no extrinsic aetiological factor can be identified, the process is assumed to be the result of a failure ofthe regulatory system, allowing the spontaneous expansion of a clone of autoreactive lymphocytes. The defect may be generalised or specific to certain groups of self-antigens and thus the autoimmune disease may be either multi- or unisystemic. The recent development of techniques to enumerate and measure the functional activity of the suppressor lymphocytes which control the effector limbs of the immune system has enabled investigators to test whether the various purported autoimmune diseases do have as their basis a generalised defect in immunoregu lation. Assessment of antigen-specific immunoregulatory function is, however, not yet readily available. liver Membrane I Antigen (LIM) I Liver I HLA, A, B, C, Sensitisation to Specific -;::!IIIL. .

The discovery of specifically acquired immunity which followed the major contributions of Louis Pasteur completely over-shadowed the first studies of the host's natural resistance. Later, the exquisite sensitivity and precision of antigen-antibody reactions made the study of immunochemistry much more attractive than the rather primitive and ambiguous field of non-specific immunity. Neverthe less, during the last three decades, a considerable body of informa tion was developed and also means by which natural resistance could be enhanced or depressed by exogenous agents such as lipopolysaccharides or BCG. An important advance was the chemical recognition of the biologically active components of these agents which in turn allowed the synthesis or" analogues. More recently, endogenous host products which can play a role in nonspecific immunity, such as thymic hormones, have also been identified, produced and used both experimentally and clinically. It therefore seemed worthwile to Drs. Miescher and Mueller-Eberhard to devote two volumes of Seminars in Immunopathology to the topic of Immunostimuhltion. Because of the good response obtai ned from readers, Springer Verlag decided to issue a hard cover book and asked their guest editor to make a preface. Prefaces, although they are found in the opening pages, are always written after the first issue has been completed."

From the first to the third of August, 1980, an international sym posium entitled "New Trends in Allergy" was held in Munich, sponsored by the Ludwig-Maximilian University, Munich, in cooperation with the German Society for Allergy and Immunity Research and the European Society for Dermatological Research. The symposium pursued two main goals: to bring allergy oriented colleagues from various specialties such as dermatology, otorhinolaryngology, pediatrics, internal medicine, immunology, and pulmonology together for interdisciplinary contacts and dis cussions; and to attract internationally known experts in an effort to disseminate information on new and fundamental develop ments in allergology. The fact that English has become the lingua franca at congresses for the exchange of ideas in medical specialties led to the decision to hold the symposium in English. In spite of the mild handicap this posed for some participants, it was also a major factor in the symposium's success. This book contains the papers delivered by the invited speakers together with the poster presentations. They cover both basic ex perimental research as well as clinical problems in allergology."

Bone marrow transplantation, the goal which integrates hemato logists, immunologists, geneticists, oncologists and specialists of several other fields, has overcome its state of stagnation in recent years. Clinically as well as experimentally new approaches to old problems and new conclusions from recent findings proliferate: bone marrow transplantation in leukemic remission, bone marrow growth in cell culture, bone marrow manipulation with antisera, bone marrow differentiation in histoincompatible hosts, immuno suppression with partial body irradiation to cite just a few. These and other new developments were discussed by experts from 12 countries in and outside the European Community during an international seminar held on March 8-10, 1979 by the "Institut fur Hamatologie, GSF," under the auspices of the European Communities. The editors thank both the contributors to this symposium, who made it a successful meeting and submitted their manuscripts punctually, and the publishers, who have provided a volume of high quality in good time. They are also grateful for the valuable cooperation from numerous colleagues at the Institut fur Hamato logie."

The subject of immune deficiency has become of special importance for two reasons. First, conditions with well defined defects in the immune system could be analyzed as "experiments of nature" in terms of finding out the accurate biological relevance of the defective link in the immune system. Secondly, the recognition of immune deficiency states has become important in order to provide the patients with the treatment necessary to remedy these defects. With regard to immune deficiency states in patients, these have been instrumental as "experiments of nature" in the revelation by Drs. Good and Cooper and their associates of the two-component structure of the immune system, a discovery which can be consi dered as a major breakthrough in the history of immunopathology. Today's research allows us to go far beyond this basic two component structure with the assessment of disorders affecting either cell to cell interactions or regarding subsets of lymphocyte populations. Furthermore, the association of immune deficiency with distinct enzymatic defects of purine metabolism is opening the door to the molecular level of immune deficiency. Dr. Cooper and Dr. Lawton have succeeded in obtaining the collaboration of the leaders in the field of immune deficiency. In view of the importance of their contributions in scientific and clinical terms, we decided to prepare a book version of the two issues of Seminars in Immunopathology devoted to this subject."

The first book to explore food allergies in the United States from the perspective of disability and race Are food allergies disabilities? What structures and systems ensure the survival of some with food allergies and not others? Allergic Intimacies is a groundbreaking critical engagement with food allergies in their cultural representations, advocacy, law, and stories about personal experiences from a disability studies perspective. Author Michael Gill questions the predominantly individualized medical approaches to food allergies, pointing out that these approaches are particularly problematic where allergy testing and treatments are expensive, inconsistent, and inaccessible for many people of color. This thought-provoking book explores the multiple meanings of food allergies and eating in the United States, demonstrating how much more is at stake than we realize, at a critical time when food allergies are on the rise: An estimated 32 million Americans, including one in thirteen children, have food allergies. Diagnoses of food allergies in children have increased by 50 percent since 1997. Yet as the author makes clear, the whiteness of the food allergy community and single-identity disability theory is inherently limiting and insufficient to address the complex choices that those with food allergies make. Gill argues that racism and ableism create unique precarity for disabled people of color that food allergic communities are only beginning to address. There is a huge disparity in access to testing and treatment, with African American and Latinx children having higher risk of adverse outcomes than white children, including more rates of anaphylaxis. Food allergy professionals have a responsibility to move beyond individualized approaches to more robust coalitional efforts grounded in disability and racial justice to undo these patterns of exclusion. Allergic Intimacies celebrates the various creative ways food allergic communities are challenging historical and current practice of exclusion, while identifying the depth of work that still needs to be done to shift focus from a white allergic experience toward a more representative understanding of the racial, ethnic, religious, and economic diversity of those in the United States. Gill's book is a discerning and vital exploration of the key debates about risks, dangers, safety, representations, and political concerns affecting the lives of individuals with food allergies.

This book is intended as a manual and offers an essential tool for practicing and occupational dermatologists, for postgraduates training in dermatology and allergo-immunology, and for allergologists and occupational physicians. Moreover, the authors include information from the world literature, addressing the needs of those who work in industrial fields and are concerned about the dermatological safety of products. The book provides a handy update on this complex, rapidly evolving research area, and in particular, an in-depth analysis of its clinical aspects. It will enable dermatologists to recognize the various clinical manifestations of the condition, make a prompt diagnosis and choose the most effective treatment. Contact dermatitis, a vast and fascinating field of study, has a high frequency of occurrence worldwide in both children and adults of both sexes, and during their daily routine, dermatologists invariably encounter many patients with this disease. To ensure the proper management of these patients it is necessary first of all to formulate a clinical diagnosis on accurate morphological grounds, since it is the most clinically polymorphic disease in dermatology and hence very demanding in terms of differential diagnosis. Then, to achieve properly targeted prevention for each patient, it is essential to isolate the causes among the numerous etiological chemical agents present in both working and leisure time activities and environments. The aim of this book is therefore two-fold: firstly to provide information on the various clinical features of contact dermatitis and review their differential diagnosis, and secondly to provide a comprehensive etiological overview. Particular attention has been paid to the methodologies and importance of patch tests and other diagnostic tools, as well as to the principles of prognosis, treatment and rehabilitation, together with considerations on some preventive aspects underlying contact dermatitis. A wealth of color clinical images, as well as tables and explanatory diagrams, round out the book.

An eye-opening investigation - combining reporting, history and cutting-edge science - into allergies and their rise in recent decades Hay fever. Peanut allergies. Eczema. Billions of people worldwide have some form of allergy; millions have one severe enough to seriously endanger their health. And over the past decade, the number of people diagnosed with allergy has been steadily increasing, an ever-growing medical burden on individuals, families, and our health care system. Medical anthropologist Theresa MacPhail, herself an allergy sufferer whose father died of a bee sting, set out to understand why. The result is a holistic and deeply researched examination of allergies, from their first medical description in 1819 to the mind-bending new treatments that are giving patients hope. MacPhail spent years interviewing hundreds of experts, patients and activists, in an effort to understand how recent changes in our environment and lifestyle are contributing to the dramatic rise in cases globally. Pollution, chemicals, antibiotics and, increasingly, climate change are all making our immune systems become more and more irritated. But, as she shows us in Allergic, understanding what is irritating us and why will help us to craft better environments in the future-so we can all breathe easier.

In recent years, our understanding of the unified airway concept has become paramount in the diagnosis, treatment, and management of sinonasal, airway, and respiratory disorders. The relationship between sinonasal inflammatory disorders, such as chronic rhinosinusitis, and pulmonary disorders, such as asthma or cystic fibrosis, is being examined more closely than ever before. This volume comprehensively reviews and discusses the unified airway approach, and more closely examines the relationship between sinonasal inflammatory disorders and pulmonary disorders. The text is formatted as an easy to read reference with bulleted points and sample case studies that maximize the clinical value of the evidence and data described. In addition to exploring chronic rhinosinusitis in patients with asthma and cystic fibrosis, other topics include pediatric chronic rhinosinusitis, aspirin-exacerbated respiratory disease, chronic bronchiectasis, primary ciliary dyskinesia, immunodeficiencies, and the unified airway microbiome. Rhinologic Disease and Respiratory Disorders will be an invaluable guide for practicing otolaryngologists, allergists, pulmonologists, otolaryngologists-in-training, and rhinologists. Foreword written by David W. Kennedy and Elina M. Toskala.

Skin physiology assessment is moving from a descriptive approach to a deeper understanding of biophysical and biochemical processes in the stratum corneum, such as epidermal barrier function and stratum corneum hydration. New, non-invasive approaches offer reliable and reproducible methods for product testing in the pharmaceutical and cosmetic industry, as well as in basic research. While standard instruments focus on functional aspects, innovative devices offer a deeper understanding of underlying mechanisms. This book discusses the assessment of skin physiology and of skin functions in clinical studies using non-invasive biophysical instruments, offering readers a comprehensive guide to planning, performing and evaluating the results of scientific studies in skin measurement and the legal framework for these studies. Written by leading experts in the field, it focuses on practical aspects of non-invasive measurements. After introducing the legal aspects of the current framework for clinical cosmetic studies and basic research in cosmetology, it explores the technical practicalities of organizing a testing lab and the pre-requirements for planning a study. The third and main section addresses specific topics in cosmetic testing e.g. skin hydration, and also includes chapters on sensory aspects and in vivo skin structure vizualization. This new, updated edition of Practical Aspects of Cosmetic Testing is a valuable tool for researchers, students, and medical staff wanting to gain insights into how best to assess skin functions in controlled studies using non-invasive biophysical instruments.

This book will address the growing roles of epigenetics in disease pathogenesis, and review the contribution of epigenetic modifications to disease onset and progression. The roles that epigenetics plays in facilitating effects of the environment on allergy and immunologic diseases will be reviewed. The book is divided into three parts - the first is an introduction to epigenetics and the methods that have been developed to study epigenetics, the second addresses epigenetics in allergic diseases and the third part will cover epigenetics in autoimmune diseases. With the rapid expansion of knowledge of how genes are regulated and how this regulation affects disease phenotypes, this book will be attractive to experienced researchers as well as those just launching an epigenetics research program. It will also be of interest to allergist, immunologists, rheumatologists and dermatologist who are engaged in clinical practice as a resource for understanding the basis for personalized and precision medicine. For example, the role that epigenetics plays in the pathogenesis in various allergic and autoimmune disorders and how this determines disease phenotypes will be covered extensively in this book. This book will thus help fill the gap in available resources on epigenetics in allergy and autoimmune diseases.

This book contains twelve chapters contributed by prestigious international experts who are at the forefront of B cell research, and aims to provide a cutting-edge and comprehensive overview of all aspects of B cells, including B cell development, maturation and activation, germinal center reaction, memory and plasma cell differentiation, and antibody-mediated positive and negative regulation of humoral immune responses. There are also three chapters describing human diseases caused by B cell abnormalities, including primary antibody deficiencies, autoimmune diseases, and B cell malignancies. We hope that this book will become a standard and routine reference for both basic researchers and clinicians.
