The third component of complement, C3, is one of the most versatile proteins and an important participant in immune surveillance and immune response pathways. Its multifunctio nality is based on its ability to interact specifically with multiple serum complement proteins, cell surface receptors, and mem brant;-associated regulatory proteins. One of its most intriguing strategies of interaction with cell surfaces is the covalent binding of activated C3 through the internal thioester. The field has expanded over the past 10 years and a wealth of information has accumulated. C3 from various species and many of the human C3 binding proteins have been cloned and expressed. Numerous cellular responses mediated by the diffe rent fragments of C3 have been described. The findings that C3 interacts in a ligand-receptor-like fashion with proteins of nonself origin such as the gC of herpes simplex virus, a 70-kDa protein from Candida albicans, proteins from Epstein-Barr virus, etc. has opened a new field of investigation. The papers assembled in this volume summarize the wealth of data on the various aspects of the C3 interactions; together they bring to the reader new information on the chemistry, molecular gene tics, biology, and pathophysiology of C3 and C3-binding proteins. Emphasis is given to structural features as they relate to functions. Spring 1989 JOHN D. LAMBRIS, HANS J. MULLER-EBERHARD Table of Contents J. E.

This book provides comprehensive up-to-date information on the structure and function of immunoglobulins. It describes the basic features of these molecules, which assists the reader in understanding how they function as an integral part of the immune system. The Immunoglobulins describes the localization and structure of different binding sites of immunoglobulin molecules, including the antigen-binding site, on the basis of latest x-ray crystallography studies. It discusses recently developed biotechnological methods that allow scientists to obtain fully active antibody molecules in vitro even without immunization and to construct new variants of immunoglobulins and their fragments by fusing with various other active molecules. A survey of recent knowledge on immunoglobulin-binding molecules other than antigens and on flexibility of immunoglobulin molecules concludes the discussion of functional aspects of the problem. Describes recent reviews on the structure and function of immunoglobulin molecules of various species Summarizes in detail recent findings on the fine structure of the antigen-combining site Presents comparative data on the antigen-recognizing sites of other molecules such as MHC proteins and T-cell receptors Summarizes growing data on immunoglobulin binding sites responsible for the reaction of immunoglobulins with molecules other than antigens Explores the rapid advance of recent biotechnological methods used for the construction of antibody molecules and their fragments with new properties Presents extensive references and is lavishly illustrated
This book has been cunningly designed to provide an overview of our current knowledge about the innate immune systems of these three types of organisms. It not only covers the innate immune mechanisms and responses of such diverse organisms as plants, Cnidaria, Drosophila, urochordates and zebrafish, but also the major receptor systems in mammalians and humans. It delves too into the central defense mechanisms, antimicrobial peptides and the complement system.
The comparative approach to immunology can be traced to the era of Pasteur and Metchnikov in which observations regarding foreign recognition in invertebrates was a factor in the develop ment of the principal concepts that created the foundation of what now is the broad field of immunology. With each major experimental and conceptual breakthrough, the classical, albeit essential, question has been asked "are the immune systems of phylogenetically primitive vertebrates and invertebrates similar to that of mammals?" Somewhat surprisingly for the jawed verte brates, the general answer has been a qualified form of "yes", whereas for agnathans and invertebrate phyla it has been "no" so far. The apparent abruptness in the appearance of the immune system of vertebrates is linked to the introduction of the somatic generation of the diversity of its antigen specific receptors. Therefore the questions regarding the origin and evolution of the specific immune system revolve around this phenomenon. With respect to the origin of the system (aside from the or igin of the rearranging machinery itself, the study of which is still in its infancy) one can ask questions about the cellular and mo lecular contexts in which the mechanism was introduced.
Offering a broad appeal to microbiologists, immunologists, and infectious disease specialists, this four volume encyclopedia covers all autoimmune, tropical, and infectious diseases. Emphasis will also be placed on genetics, physiology, metabolism, pathogenesis and applied microbiology. Under the leadership of some of the most world renowned names in the field, the encyclopedia will bring together an outstanding collection of contributions by top scientists in a variety of fields. Volumes 1-3: Diseases will be divided by the 11 main sections of the body, namely Integumentary, Skeletal, Respiratory, Digestive, Urinary, and Reproductive. For some of the autoimmune disease, more then one system will be involved but the delineation serves to broadly break down the diseases into systems. Volume 4 will cover the vaccines for said diseases and future prospects will be offered by leaders in industry and academia. Volume 4 will also be broken down into all the body systems, as in the other two volumes. For each vaccine, for each disease, and in each system the following will be included: • A list of the vaccines currently available along with a list of the companies that manufacture them • Molecular Immunology of the Vaccine • Type of Immunity involved in protection • Mode of Vaccination for each vaccine; repeated boosters and length of immunological memory • Commercial production of vaccines • Storage of vaccines • Standardization and Control of Vaccines • WHO programs and World-Wide Disease Eradication Programs based upon Vaccines.
