This book is about the phenotypic and functional features of epidermal Langerhans cells in experimental models and in clinical medicine. Langerhans cells, members of the dendritic cell system in the skin, are critically involved in the regulation of cell-mediated immune responses and gain increasing attention in a wide spectrum of clinical areas such as allergy, autoimmunity, transplantation and resistance to tumors and infections. The book covers the latest, most timely developments in this rapidly advancing field. Leading researchers describe functional analyses at the cell and molecular level, elucidating processes related to antigen presentation and the role of cytokines, and discuss perspectives for a future use of Langerhans cells and other dendritic cells in the immunotherapy of various diseases.

Epidermal Langerhans Cells focuses on epidermal Langerhans cells (LCs) and the important role they play in the induction of contact hypersensitivity and graft rejection. This in-depth work discusses how these antigen-presenting cells are modulated by various physicochemical agents (such as UV light) and how they can be infected by the AIDS virus. It also reveals that cytokines mediate their development into potent T cell-stimulatory dendritic cells. This comprehensive review covers important experimental details and methods, and fascinating information on LCs. It also provides an overview of the immune system as it relates to the skin in health and disease. This up-to-date publication is an indispensable resource for all investigative and clinical dermatologists, as well as immunologists interested in antigen-presenting cells.

Over the generations the skin has been the site for immunization against smallpox. This method of immunization was described in a letter written by Lady Mary Montagu on April 1, 1717 in Adrianopole, Turkey: "The small-pox, so fatal, and so general amongst us, is here entirely harmless by the invention of ingrafting, which is the term they give it. . . The old woman comes with a nut-shell full of the matter of the best sort of small-pox . . . She immediately rips open (the skin) with a large needle . . . and puts into the vein as much venom as can lie upon the head of her needle, and after binds up the wound. There is no example of anyone that died of it; and you may believe that I am satisfied of the safety of this experiment since I intend to try it on my dear little son" (Letters from the right Honourable Lady Mary Montagu 1709-1762. Published by J. M. Dent and Co. London, 2nd edition, September, 1906, p. 124. ) The "variolation" method was, 80 years later, markedly improved by the use of cowpox virus, as reported by Edward Jenner in 1796. The successful method of intradermal immunization against smallpox and later against other virus diseases is in fact based on the presence of anitigen-presenting dendritic cells in the skin.

This volume of Current Topics in Microbiology and Immunology covers diverse topics related to intradermal immunization. The chapters highlight the effectiveness of intradermal immunization in experimental animal models or in clinical practice, all supporting the view that intradermal immunization is at least as good as other immunization routes. Keeping in mind that current vaccines are not specially designed for intradermal immunization, but show comparable efficiency even at reduced dosages, this underlines the great potential for the skin as a vaccination site. Hopefully, the overview in this volume will encourage vaccine designers to focus on this promising immunization route, and in addition, to inspire them to develop vaccines that are especially optimized for intradermal immunization.

This book reviews the role of each cell subset in the skin, providing the basics for understanding skin immunology and the mechanisms of skin diseases. The skin is one of the immune organs and is continually exposed to foreign antigens and external stimuli that must be monitored and characterized for possible elimination. Upon exposure to foreign antigens, the skin can elicit a variety of immune responses in harmony with skin components that include keratinocytes, dendritic cell subsets, mast cells, basophils, fibroblasts, macrophages, gamma-delta T cells, neutrophils, myeloid-derived suppressor cells, vascular and lymphatic cells, hair follicles, platelets, and adipose tissues, among others. In the past 10 years, knowledge of immunology has expanded drastically in areas such as innate immunity (Toll-like receptors, C-type lectins), and host defenses to bacteria and viruses, and this increased knowledge has led to the development of more effective treatment of psoriasis and other skin diseases. This book provides updates on the mechanisms of skin diseases including contact dermatitis, atopic dermatitis, psoriasis, urticaria, drug eruption, bullous diseases, anaphylaxis, graft-versus-host disease, rosacea, lymphoma, photodermatology, and collagen vascular diseases. Understanding the basics of skin immunology will help clinicians and dermatologists use new therapeutics such as biologics efficiently. Serving as an intermediary between basic science and clinical medicine, this book gives readers the opportunity to understand and marvel at the mystery and fascination of skin immunology.

More than 50 million Americans, one out of five, suffer from hay fever, asthma, and other allergic diseases. Many of these conditions are caused by exposure to allergens in indoor environments such as the house, work, and schoolâ€"where we spend as much as 98 percent of our time. Developed by medical, public health, and engineering professionals working together, this unique volume summarizes what is known about indoor allergens, how they affect human health, the magnitude of their effect on various populations, and how they can be controlled. The book addresses controversies, recommends research directions, and suggests how to assist and educate allergy patients, as well as professionals. Indoor Allergens presents a wealth of information about common indoor allergens and their varying effects, from significant hay fever to life-threatening asthma. The volume discusses sources of allergens, from fungi and dust mites to allergenic chemicals, plants, and animals, and examines practical measures for their control. Indoor Allergens discusses how the human airway and immune system respond to inhaled allergens and assesses patient testing methods, covering the importance of the patient's medical history and outlining procedures and approaches to interpretation for skin tests, in vitro diagnostic tests, and tests of patients' pulmonary function. This comprehensive and practical volume will be important to allergists and other health care providers; public health professionals; specialists in building design, construction, and maintenance; faculty and students in public health; and interested allergy patients.

These Proceedings contain the contributions of the partIcIpants of the Third International Symposium on Dendritic Cells that was held in Annecy, France, from June 19 to June 24, 1994. This symposium represented a follow-up of the first and second international symposia that were held in Japan in 1990 and in the Netherlands in 1992. Dendritic cells are antigen-presenting cells, and are found in all tissues and organs of the body. They can be classified into: (1) interstitial dendritic cells of the heart, kidney, gut, and lung;(2) Langerhans cells in the skin and mucous membranes; (3) interdigitating dendritic cells in the thymic medulla and secondary lymphoid tissue; and (4) blood dendritic cells and lymph dendritic cells (veiled cells). Although dendritic cells in each of these compartments are all CD45+ leukocytes that arise from the bone marrow, they may exhibit differences that relate to maturation state and microenvironment. Dendritic cells are specialized antigen-presenting cells for T lymphocytes: they process and present antigens efficiently in situ, and stimulate responses from naive and memory T cells in the paracortical area of secondary lymphoid organs. Recent evidence also demonstrates their role in induction of tolerance. By contrast, the primary and secondary B-cell follicles contain follicular dendritic cells that trap and retain intact antigen as immune complexes for long periods of time. The origin of follicular dendritic cells is not clear, but most investigators believe that these cells are not leukocytes.
