Anti Idiotype Antibodies In Cancer Treatment

Actively induced immunotherapy is one of the most promising fields in cancer research and numerous approaches are being studied to design effective cancer vaccines. Among the treatment strategies to develop an effective immune response against tumor associated antigens is the use of anti idiotype (Ab2) mAb as antigen surrogates. Several studies in animal models have demonstrated the efficacy of these vaccines for triggering the immune system to induce specific and protective immunity against tumors of different origin. In fact, anti-idiotypic mAbs have been used successfully in cancer therapeutics to overcome the poor immunogenicity of some tumor-associated antigens, in particular those of non-protein origin. In some clinical trials, including patients with different tumors, anti-Id specific humoral and/or cellular responses following immunization were associated with improved clinical outcome. This number of Frontiers will be dedicated to anti- idiotypic antibodies and their use in cancer treatment. Different article types will be considered: original contributions, case reports, methods, hypothesis and theory, reviews, historical, etc.

The goal of this book is to present findings which are supportive of the concept that the words of the idiotype dictionary and likewise self-recognition are essential for communication between lymphocyte clones while some unfaithful ( infidel ) copies of the words contained in the idiotype dictionary perhaps play a role in the functional regulation of nonlymphoid cells.

Vaccines have historically been considered to be the most cost-effective method for preventing communicable diseases. It was a vaccine~hat enabled global eradication of the dreaded disease smallpox. Mass immunization of children forms the anchor of the strategy of the World Health Organization (WHO) to attain "health for all" status by the year 2000. Vaccinology is undergoing a dimensional change with the advances that have taken place in immunology and genetic engineering. Vaccines that confer short or inadequate immunity or that have side effects are being replaced by better vaccines. New vaccines are being developed for a variety of maladies. Monoclonal antibodies and T cell clones have been employed to delineate the immunodeterminants on microbes, an approach elegantly complemented by computer graphics and molecular imaging techniques. Possibilities have opened for obtaining hitherto scarce antigens of parasites by the DNA recombinant route. Better appreciation of the idiotypic network has aroused research on anti-idiotypic vaccines. Solid-phase synthesis of peptides is leading to an array of synthetic vaccines, an approach that is expected to attain its full potential once the sequences activating suppressor cells are discovered and the rules for presentation of antigens to T and B cells are better worked out. A new breed of vaccines is on the horizon that seeks to control fertility.

This is the most comprehensive review of the idiotypic network available. All the current knowledge of idiotypes of the various antibodies is incorporated in this volume. The pathogenic role of idiotypes in autoimmunity and cancer is reviewed in depth. The therapeutic part focusses on harnessing anti-idiotypes for treating autoimmunological disorders, and on the employment of idiotypes for vaccines in cancer and infectious diseases, as well as explaining the manipulation of the idiotypic network in autoimmunity and cancer idiotypes and vaccines.

This long overdue title provides a comprehensive, up-to-date, state-of-the art review of approved biologic therapies, with coverage of mechanisms of action, Indications for therapy, immunogenicity and a detailed examination of adverse effects and safety of the many and diverse therapeutic agents presented in a total of 13 chapters. It is predicted that by 2016, biologics will make up half of the world's 20 top-selling drugs and by 2018, biologic medicine sales will account for almost half of the world's 100 biggest selling drugs. Recombinant proteins dominate the growing list of the more than 200 approved biotherapeutic agents with targeted antibodies, fusion proteins and receptors; cytokines; hormones; enzymes; proteins involved in blood-clotting, homeostasis and thrombosis; vaccines; botulinum neurotoxins; and, more recently, biosimilar preparations, comprising the majority of approved biologics. Written with clinicians, other health care professionals, and researchers in mind, Safety of Biologics Therapy examines, in a single volume, the full range of issues surrounding the safety of approved biologic therapies. A good understanding of the risks and safety issues of modern biologics therapy is increasingly being demanded of all those connected with their development, handling, prescribing, administration and subsequent patient management. In addition to being of great value to clinicians in all branches of medicine, and to nurses, pharmacists and researchers, this book will prove invaluable for students taking undergraduate and graduate courses in the above disciplines and in the biomedical sciences.

KENNETH A. FOON and ALTON C. MORGAN, JR. Passive immunotherapy using heteroantisera for the treatment of cancer in animals and humans has been studied for over 50 years. Attempts have been made to treat animal tumors with sera from immunized syngeneic, allogeneic, or xenogeneic animals. A number of studies of passive immunotherapy using heterologous antisera in humans have also been performed. These studies have generally been attempted in patients with large tumor burdens, and as would be expected, results have been transient at best. A wide variety of solid tumors as well as leukemias and lym phomas have been treated with antisera raised in sheep, horses, rabbits, and goats. Problems such as anaphylaxis, serum sick ness, and severe cytopenias have been encountered with these antisera. There are a number of potential mechanisms by which unconju gated antibodies might be cytotoxic to tumor cells. Antibodies bound to the cell surface membrane of tumor cells may lead to cell lysis by complement-dependent or antibody-dependent cellu lar cytotoxicity. Circulating tumor cells bound by antibody may be more susceptible to phagocytosis by the reticuloendothelial system. Antibody bound to the cell surface membrane of tumor cells may enhance immunogenicity of the tumor cell leading to activation of the host's immune system.

A comprehensive account of cancer immunity and immunotherapy, examining recent results, current areas of interest and the specific issues that are affecting the research and development of vaccines. It provides insight into how these problems may be overcome as viewed by leaders in the field.
