Book excerpt: Humanized mouse models have become increasingly valuable tools to study human hematopoiesis and infectious diseases. However, human T cell differentiation remains inefficient. We generated mice expressing human interleukin (IL-7), a critical growth and survival factor for T cells, under the control of murine IL-7 regulatory elements. After transfer of human cord blood-derived hematopoietic stem and progenitor cells, transgenic mice on the NSGW41 background, termed NSGW41hIL7, showed elevated and prolonged human cellularity in the thymus while maintaining physiological ratios of thymocyte subsets. As a consequence, numbers of functional human T cells in the periphery were increased without evidence for pathological lymphoproliferation or aberrant expansion of effector or memory-like T cells. We conclude that the novel NSGW41hIL7 strain represents an optimized mouse model for humanization to better understand human T cell differentiation in vivo and to generate a human immune system with a better approximation of human lymphocyte ratios.
Book Synopsis Differentiation, Tissue Adaptation and Function of Memory T Cells by : Weiguo Cui
Download or read book Differentiation, Tissue Adaptation and Function of Memory T Cells written by Weiguo Cui and published by Frontiers Media SA. This book was released on 2020-06-16 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upon antigen encounter, naïve T cells differentiate into (i) effectors that combat infected or malignant cells, and at later time points, into (ii) memory cells that provide long-lasting immunity. This differentiation process allows some T cells to leave the confines of secondary lymphoid organs and to enter peripheral tissues in search of pathogens or tumor cells. These different environments pose specific challenges for effector and memory T cells to maintain homeostasis. T cells directed into the lungs are likely to encounter higher levels of oxygen, but lower amounts of nutrients than those directed into the intestinal epithelium. In addition to oxygen tension and nutrient concentrations, other key factors, such as the commensal flora and stromal components, create unique conditions that require tissue-specific adaptations of T cells. These steady state conditions can dramatically change during infection when inflammatory mediators and T cell growth factors are released, requiring the immediate response of T cells. The gradual changes imposed by growing tumors can also be challenging for T cells due to competition with rapidly cycling tumor cells that deplete essential resources of oxygen and glucose. The strategies that T cells employ to respond to the diverse cues from their surroundings are the focus of current research. It appears that next to circulating memory T cells that are confined to the circulation and those that survey all of the peripheral tissues, dedicated populations of resident memory T cells exist that can optimally adapt to the local circumstances within each tissue. Restrictions on the metabolic requirements of T cells residing in tumor tissue have been found to directly impact on effector functions such as cytokine production. The fundamental principles of how the machinery of T cells can translate local cues into tissue-specific differentiation processes are fascinating and warrant further investigation.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last several years the field of humanized mice has matured and developed into an essential component of translational research for HIV/AIDS. Humanized mice serve both as vehicles for discovery and as highly sophisticated platforms for biomedical research. In addition, humanized mice have demonstrated outstanding potential for the investigation of critical aspects of the infection and pathogenesis of the hepatitis and herpes viruses, as well as highly relevant microbial infections such as tuberculosis and malaria. Humanized Mice for HIV Research provides a comprehensive presentation of the history, evolution, applications, and current state of the art of this unique animal model. An expansion of twelve review articles that were published in Humanized Mice by Springer in 2008 (Eds: Nomura T, Watanabe T, Habu S), this book expertly captures the outstanding progress that has been made in the development, improvement, implementation, and validation of humanized mouse models. The first two parts of this book cover the basics of human-to-mouse xenotransplantation biology, and provide critical information about human immune cell development and function based on individual models created from different immunodeficient strains of mice. The third and fourth parts investigate HIV-1 biology, including different routes of transmission, prevention, treatment, pathogenesis, and the development of adaptive immunity in humanized mice. The fifth part shows the broad applicability of humanized mice for therapeutic development, from long-acting antiretroviral combinations to genetic manipulations with human cells and cell-based approaches. The sixth part includes liver tissue engineering and the expansion of humanized mice for many other human cell-tropic pathogens.

Book Synopsis Cancer and Autoimmunity by : M.E. Gershwin
Download or read book Cancer and Autoimmunity written by M.E. Gershwin and published by Elsevier. This book was released on 2000-03-27 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the two disciplines in parallel development for two decades, tumor immunology and transplantation immunology, the latter has thrived and has led to some of the most critical discoveries in immunobiology. The former continues to thwart both scientists and clinicians alike.The goal of immunologists in modern day research is to develop a simple and effective means to manipulate cancer in vivo, possibly encompassing several venues: identifying a phenotypic marker and the use of either active or passive immunization; include the use of passive reagents carrying "warheads" to selectively destroy cancer cells; or altering the basic process of cell survival.This excellent multidiscipline-authored volume presents a theme which has not been well described before. The papers include both basic and clinical science and range from sophisticated molecular biology to little more than phenomenology (e.g. the increased association of cancer in some autoimmune diseases and increased presentation of autoimmune phenomena in malignant condition). This, however, is state-of-the-art.This collection of themes will be of use not only to bench scientists, but also to clinicians who treat patients. The book represents progress at the cutting edge of this discipline, and points the way to further developments in the "black box" of immunology.

Book Synopsis Cancer Research: An Interdisciplinary Approach by : Nima Rezaei
Download or read book Cancer Research: An Interdisciplinary Approach written by Nima Rezaei and published by Springer Nature. This book was released on 2023-07-03 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer is a major public health concern and one of the leading causes of death. There is no simple solution for this complex disease, therefore interdisciplinary approaches might help to find solutions to many unanswered questions and challenges about cancer. The rapid flow of interdisciplinary research in cancer during recent years has increased our understanding of the nature of cancers. Such interdisciplinary approaches could be helpful for both the diagnosis and the development of more effective therapeutic strategies. The “Interdisciplinary Cancer Research” series publishes comprehensive volumes on different cancers and presents the most updated and peer-reviewed articles on human cancers. Over the past decade, increased cancer research has greatly improved our understanding of the nature of cancerous cells which has led to the development of more effective therapeutic strategies to treat cancers. This interdisciplinary series is of special value to researchers and practitioners working on cell biology, immunology, hematology, biochemistry, genetics, oncology and related fields. This is the main concept of Cancer Immunology Project (CIP), which is a part of Universal Scientific Education and Research Network (USERN).

Book Synopsis Analysis of Cancer Risks in Populations Near Nuclear Facilities by : National Research Council
Download or read book Analysis of Cancer Risks in Populations Near Nuclear Facilities written by National Research Council and published by National Academies Press. This book was released on 2012-06-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late 1980s, the National Cancer Institute initiated an investigation of cancer risks in populations near 52 commercial nuclear power plants and 10 Department of Energy nuclear facilities (including research and nuclear weapons production facilities and one reprocessing plant) in the United States. The results of the NCI investigation were used a primary resource for communicating with the public about the cancer risks near the nuclear facilities. However, this study is now over 20 years old. The U.S. Nuclear Regulatory Commission requested that the National Academy of Sciences provide an updated assessment of cancer risks in populations near USNRC-licensed nuclear facilities that utilize or process uranium for the production of electricity. Analysis of Cancer Risks in Populations near Nuclear Facilities: Phase 1 focuses on identifying scientifically sound approaches for carrying out an assessment of cancer risks associated with living near a nuclear facility, judgments about the strengths and weaknesses of various statistical power, ability to assess potential confounding factors, possible biases, and required effort. The results from this Phase 1 study will be used to inform the design of cancer risk assessment, which will be carried out in Phase 2. This report is beneficial for the general public, communities near nuclear facilities, stakeholders, healthcare providers, policy makers, state and local officials, community leaders, and the media.

Book Synopsis Cellular, Molecular, and Clinical Aspects of Allergic Disorders by : Sudhir Gupta
Download or read book Cellular, Molecular, and Clinical Aspects of Allergic Disorders written by Sudhir Gupta and published by Springer. This book was released on 2012-12-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Impressive progress has been made in the general field of immunology which has made possible new understanding and pragmatic approaches to the patient with allergic disease. Indeed, one working in the field of immunology senses a major revolution of immunobiologic thinking, much of which has relevance to the clinical practice of allergy. To the practicing allergist, pediatrician, or internist who must deal with allergic patients, the surging new information may seem confusing and bewildering. As part of our comprehensive series on modern immunobiology which aims to digest this progress, we believe it is appropriate to devote an entire volume to the fundamental principles, new knowledge, and clinical lore on which the modern practice of allergy must be based. In the present volume we strive to bring together relevant contributions from leaders in the field of immunobiology with those whose work stands at the forefront of clinical practice. The advancing understanding has in numerous instances reached the point of clinical application, and we have tried to encompass in this volume the entire scope of modern allergy.
Download or read book T Cell Hybridomas written by H.v. Boehmer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than ten years cell fusion techniques have been applied in studies on various lymphocyte functions. Ig expression was first studied in hybrids obtained by fusing myeloma cells with fibroblasts (1) or lymphomas (2), both of which do not produce Ig, and with Ig producing myelomas (3) or human blood lymphocytes (4). Kohler and Milstein (5) fused a myeloma with spleen cells from immunized mice. Up to 10% of the hybrids obtained secreted antibodies specific for the immunizing antigen. This suggested that plasma cells preferenti ally fused with the myeloma cells, a finding which was of enormous practical value. It was found that both Band T lymphocytes could be fused with the T cell tumor BW5147, which is however not permissive for Ig synthesis (6). A very large number of T cell hybridomas were generated by fusing BW5147 with cell populations containing in vivo or in vitro activated cells (7). The hybrids showed no specific T cell functions and binding assays for T cell receptors were not available. In particular, no hybrids were obtained which expreS1ed specific cytolytic activity that could be tested in short-term Cr release assays (8). However, the frustrations expressed about these failures, published in January, 1978 (9), were relieved by Taniguchi and Miller's publication a few months later of T cell hybridomas producing antigen-specific suppressor factors (10). Unfortunately, their hybrids rapidly lost factor production.

Download or read book Immunobiology written by Edward Bittar and published by Elsevier. This book was released on 1996-12-17 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: As this volume demonstrates, immunobiology is a young science which is undergoing explosive growth. Judged by results, it is already an elaborate discipline which cuts across every other area in biomedical research and even has its own vocabolary (e.g., the "veto" effect). Rather than inculcate the habit of superficial learning by having the student go through a maze of details, we have sought to gather together sixteen essays that range from T-cells to psyhoneuroimmunology. This is keeping with the growing understanding that the student is expected to read and think far more for herself/himself.Next to nothing is known about innate immunity. However, recent evidence suggests that collectins might bridge the gap between innate immunity and specific clonal immune responses. Collectins are soluble effector proteins that include serum mannose-binding protein, and lung surfactants A and D. They are considered to be ante-antibodies.
