Regulatory T cells (Tregs) are a vital component of the T cell immune system by their ability to control T cell responses that would lead to autoimmune disease. Tregs also protect damaged normal cells that are healing from T cells programmed to kill any abnormal cells in the body. Cancer (tumor) develops from normal cells and can express normal self-antigens. Tregs protect precancerous cells as if they were healing damaged cells and inhibit the anti-tumor T cell response by the use of advanced effector mechanisms, which stop the T cell immune system from effectively removing the tumor. The function of cells involved in this process is controlled by the cell membrane activation of intracellular translational pathways interacting with the nucleus that produces transcriptional proteins, which control cellular behavior such as secretion of lymphokines or cell proliferation. This book examines the function and related translational pathways of Tregs, anti-tumor T cells, and cancer cells. It relates that information to the treatment of cancer by examining human clinical trials of new immune cell-based treatments (immunotherapy). The book also proposes ways to improve those treatments by manipulating the translational pathways of immunotherapeutic cells. The hope is that these new treatment proposals stimulate positive thought about the future of cancer immunotherapy.
This book addresses one of the major challenges of immunology today that is being directed to the translation of the rapidly emerging volume of basic science contributions of immunology to clinical medicine. In so doing, the book systemically introduces and discusses concepts, classifications, phenotypic and functional descriptions of regulatory T (Treg) cells in health and disease. The authors of the 15 chapters were selected from among the most qualified experts in the field of Treg cell research who provide a comprehensive overview of Treg cells and their biology in the ensuing chapters. The beginning chapters provide a useful contemporary classification of Treg cell populations and then progress to chapters that explore basic mechanisms of Treg cell function and epigenetic control. In addition to descriptions of typical CD4+ Foxp3+ cells, other chapters provide detailed presentations of Treg subsets such as CD8+ Tregs and IL-10-producing Tr1 cells. The differences of various Treg subsets, as well as circulating and resident Treg cell populations, are next compared. Importantly, the next chapters provide the clinical correlation of Treg cells with autoimmune diseases, inflammatory diseases, metabolic diseases, cancer and organ transplantation and progress to chapters that highlight emerging innovative technology including nanoparticle-Treg cells and their translational values. In summary, the book will provide a valuable resource not only for graduate students and researchers in the fields of immunology, cell biology and translational medicine but also for all others interested in learning more about Treg cells and their application in human health and disease.
Innate and adaptive immunity play important roles in immunosurveillance and tumor destruction. However, increasing evidence suggests that tumor-infiltrating immune cells may have a dual function: inhibiting or promoting tumor growth and progression. Although regulatory T (Treg) cells induce immune tolerance by suppressing host immune responses against self- or non self-antigens, thus playing critical roles in preventing autoimmune diseases, they might inhibit antitumor immunity and promote tumor growth. Recent studies demonstrate that elevated proportions of Treg cells are present in various types of cancers and suppress antitumor immunity. Furthermore, tumor-specific Treg cells can inhibit immune responses only when they are exposed to antigens presented by tumor cells. Therefore, Treg cells at tumor sites have detrimental effects on immunotherapy directed to cancer.
Regulatory T Cells in Health and Disease focuses on the mechanism by which T cells become regulatory T cells, the processes which control the number of regulatory T cells in the blood and tissue, and the ways in which regulatory T cell prevent autoimmune disease and interact with infections and cancer. - Contains contributions from leading authorities in the field of regulatory T cell biology - Informs and updates on all the latest developments in the field - Explores the processes which control the number of regulatory T cells in the blood and tissue, and the ways in which regulatory T cell prevent autoimmune disease and interact with infections and cancer
This volume illustrates the salient aspects of cancer biology relevant to the successful implementation of immunotherapy. Topics include enhancement of antigen-specific immune responses by anti-cancer vaccines, modulation of the function of T cells within the tumor microenvironment, and the effects of genetic, epigenetic, developmental, and environmental determinants on T cell function. Other topics covered include the ex vivo expansion of T or other immune cells and their genetic modification or reprogramming to increase their ability to survive and expand when adoptively transferred back to the patients. Specific attention is devoted to the genetic manipulation of T cells through the introduction of re-directed T cell receptors, chimeric antibody receptors, and other genetic manipulation aimed at improving their effectiveness as anti-cancer agents. Furthermore, the revolutionary role of checkpoint inhibitors and their potential in combination with other immunotherapeutic approaches or with standard chemo and radiation therapy are extensively discussed.
Covering one of the hottest topics in immunology today, this book provides a comprehensive view of all types of regulatory T cells described so far in the literature. The book will have broad appeal to both researchers and clinicians.
This book will cover primary roles of NKT cells in immunity to cancer, in both mouse tumor models and cancer patients. There are several chapters describing general aspects of NKT cells.
This book focusing on the immunopathology of cancers is published as part of the three-volume Springer series Cancer Immunology, which aims to provide an up-to-date, clinically relevant review of cancer immunology and immunotherapy. Readers will find detailed descriptions of the interactions between cancerous cells and various components of the innate and adaptive immune system. The principal focus, however, is very much on clinical aspects, the aim being to educate clinicians in the clinical implications of the latest research and novel developments in the field. In the new edition of this very well received book, first published in 2015, the original chapters have been significantly updated and additional chapters included on, for example, current knowledge on the roles of T-helper cells and NK cells in tumor immunity, the part played by oncoviruses in the development of various cancers, and the applications of fluorescent in situ hybridization, bioluminescence, and cancer molecular and functional imaging. Cancer Immunology: A Translational Medicine Context will be of special value to clinical immunologists, hematologists, and oncologists.
Immunotherapy is now recognized as an essential component of treatment for a wide variety of cancers. It is an interdisciplinary field that is critically dependent upon an improved understanding of a vast network of cross-regulatory cellular populations and a diversity of molecular effectors; it is a leading example of translational medicine with a favorable concept-to-clinical-trial timeframe of just a few years. There are many established immunotherapies already in existence, but there are exciting new cancer immunotherapies just on the horizon, which are likely to be more potent, less toxic and more cost effective than many therapies currently in use. Experimental and Applied Immunotherapy is a state-of-the-art text offering a roadmap leading to the creation of these future cancer-fighting immunotherapies. It includes essays by leading researchers that cover a wide variety of topics including T cell and non-T cell therapy, monoclonal antibody therapy, dendritic cell-based cancer vaccines, mesenchymal stromal cells, negative regulators in cancer immunology and immunotherapy, non-cellular aspects of cancer immunotherapy, the combining of cancer vaccines with conventional therapies, the combining of oncolytic viruses with cancer immunotherapy, transplantation, and more. The field of immunotherapy holds great promise that will soon come to fruition if creative investigators can bridge seemingly disparate disciplines, such as T cell therapy, gene therapy, and transplantation therapy. This text is a vital tool in the building of that bridge.
