This up-to-date sourcebook covers viral and bacterial superantigens (SAgs) from molecular structure and immunological processes to pathology and treatment of superantigen-mediated human diseases. Discusses diseases beyond Toxic Shock Syndrome, such as autoimmune and inflammatory skin conditions, as well as the role of superantigens in other infectious diseases. Illustrated with molecular structures of superantigens. Leading researchers in the biological, chemical, and physical investigation of superantigens describe in step-by-step detail their best experimental techniques to assess the physical characteristics and biological effects of superantigens. Their protocols range from those for investigating the interactions of superantigens with cellular receptors to those for the analysis of their immunological and biological effects, including methods for using BIOcore to determine binding kinetics and establishing various lymphocyte cell culture systems. There are also accounts of such methods as the RNase protection assay, cytokine ELISA, FACS analysis, and cytokine production at the single cell level. This is the most comprehensive book on superantigen biology written to date. It uniquely combines many aspects of superantigen biology from the basic molecular mechanisms of superantigen action to the clinical consequences of superantigen intoxication, superantigen related diseases, and measures to combat superantigen toxicity.

One look, and you'll see why it's the defnitive microbiology course and exam quick review! Everything you need to thoroughly and rapidly prepare for the exam!
Here's why this is THE definitive microbiology course and exam quick review (Condensed Table of Contents): The most CONCISE, COMPLETE, UP-TO-DATE, and USER-FRIENDLY review available An understanding of the immune system is central to the understanding of how the body interacts with its surroundings, and how it both protects itself and responds to infectious disease. But what processes underpin the body's response to infection? How does our immune system remember its previous encounters? And what happens when the tight regulation of the immune system fails? Immunity: The Immune Response in Infectious and Inflammatory Disease presents an engaging insight into one of the most intricate yet conceptually challenging biological systems. With a unique emphasis on the immune response to infection, it presents the immune system as a dynamic interface with the outside world. Building up a complete picture of the subject, the book leads the student through both innate and adaptive immunity, how infection is detected, and how the cells of the immune system interact to generate a response, before examining the immune response to bacterial, viral, and fungal and parasitic infections. Finally, the book explores the relationship between the regulation of the immune response and immunological diseases - how the immune system is controlled, and the implications for our health when this control is lost - and immune memory and the development of vaccines. Immunity combines articulate prose with striking full colour illustrations, while the unique Primers in Biology modular structure integrates text, illustrations, definitions, and literature references for each topic into one double-page spread, bringing to the student's fingertips all the tools that they need to master that topic. The immune system is one of the most challenging yet rewarding biological systems to comprehend; Immunity: The Immune Response in Infectious and Inflammatory Disease is the ideal resource for any student wishing to develop a sound grasp of this fascinating subject.

This comprehensive, up-to-date text will be of interest to graduate students,post-doctoral fellows, basic and clinical immunologists, microbiologists and infectious disease physicians, and any physician treating diseases in which immunologic mechanisms play a role. This edition features expanded coverage of regulatory T cells, innate immunity, and dendritic cells. Additional chapters on cytokines are also included. A companion Website offers the fully searchable text, plus all illustrations in full color and comprehensive lists of references. Since the discovery of viral superantigens in 1991, immunologists have made a number of new discoveries. The discoveries, especially those relating to the interplay between the immune system and viruses producing superantigens, have had a great impact on immunology and virology, as it appears that some diseases are triggered or exacerbated by viral superantigens. Viral Superantigens presents a complete review of this new area of study. Edited by a leading researcher and authored by a distinguished team of contributors, this comprehensive analysis covers every aspect of viral superantigens and related subjects, including critical topics such as effects on the T cell repertoire and viral superantigen-mediated diseases. Immunologists and virologists, clinical practitioners, and graduate students will find this book an invaluable resource to encourage further advances in research. The molecular evolution of viruses is fascinating and quite controversial, relevant to the evolution of living organisms, a determinant in pathogenesis by viruses, and amenable to detailed study in various laboratories around the globe. Evolution is the product of variation and selection. Genetic recombination is a major source of variation for evolutionary selection. Full understanding of virus evolution requires knowledge of the inventory of existing viruses, their distribution in biological space and time and their interactions with other viruses and living organisms. The basic focus of this volume will be to trace the evolution (or accumulation) of biological identity systems from molecules to microbes, through animals to primate and human social structure. Overall, the volume will be organized so that it will trace the evolution of group identification systems from simple unicellular life forms, through the ‘tree of life’ all the way to complex hominid social structures. Such an evolutionary tracing has not been previously published, thus the book will develop and present a unique organization of information. The focus of this book will also be to understand the mechanisms that allow group (social) identification and communication systems to function. Sensory identification systems, especially receptors, will be emphasized. In unicellular and early multicellular organisms, addiction modules (toxins and antitoxins, often from genetic parasites) are most commonly used as biological group identification systems. Later in evolution, odor receptors, in particular, provide a clear evolutionary trail that can be followed from microbes to humans. Photo and visual receptors are also considered along with the neurological systems that process receptor information. Visual and audio based social imprinting will also be presented. In addition, the book will seek to understand the underlying evolutionary forces that drive the creation of group identification systems. In particular, ‘addiction’ based molecular strategies will be examined. A unique element of this book will be to evaluate the role of genetic parasites in the origination of such addiction modules. The recent explosion of genomic databases and information will be called on heavily as evidence for this part of the book.
