Download or read book Role of IL 27 and TCR Stimulation in Inhibitory Receptor Expression written by Jonathan Howard DeLong and published by . This book was released on 2018 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adaptive immune response is necessary for control of pathogen burden in a wide range of infections. However, in the absence of active regulatory mechanisms, this protective response can lead to immune pathology. The cytokine interleukin (IL)-27 is required for control of exaggerated immune responses during toxoplasmosis and other infections and autoimmune settings. Multiple regulatory pathways have been found to be controlled by IL-27. However, there are gaps in our knowledge of the mechanisms by which IL-27 limits T cell responses. The present work focuses on the ability of IL-27 to promote expression of inhibitory receptors on T cells. The studies presented here establish that TCR and cytokines have distinct and complementary roles in promoting inhibitory receptor expression. In vitro, IL-27, type I IFN, and IFN-g induced expression of PD-L1 and Sca-1 on naïve murine CD4+ and CD8+ T cells in the absence of TCR stimulation. TCR stimulation induced expression of multiple inhibitory receptors and IL- 27 combined synergistically with TCR stimulation to further upregulate Ly6C, LAG-3, CTLA-4, TIGIT and TIM-3. This IL-27-mediated inhibitory expression was STAT1- dependent. The response to TCR stimulation was graded and thus a stronger TCR stimulus resulted in greater inhibitory receptor expression. In vivo, during infection with Toxoplasma gondii, IL-27 was required for full expression of Ly6C, PD-L1, LAG-3, CTLA-4, and TIGIT by parasite-specific T cells in the lung, a local site of infection, but not in the spleen. STAT1 was also required for full expression of LAG-3, CTLA-4, and TIGIT at local sites of infection. Taken together, these studies suggest a model in which inhibitory receptor expression on T cells is a graded regulatory pathway that is upregulated by exposure to increasing levels of TCR stimulation and cytokines present at sites of inflammation.

Download or read book Co signal Molecules in T Cell Activation written by Miyuki Azuma and published by Springer Nature. This book was released on 2019-11-22 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book equips young immunologists and health professionals with a clear understanding of the fundamental concepts and roles of co-signal molecules and in addition presents the latest information on co-stimulation. The first part of the book is devoted to co-signal molecules and the regulation of T cells. Following an initial overview, subsequent chapters examine each co-signal molecule in turn and discuss the mechanisms by which co-signal molecules regulate the different types of T cell. The second part covers various clinical applications, including in autoimmune disease, neurological disorders, transplantation, graft-versus-host disease, and cancer immunotherapy. To date, co-stimulation blockade and co-inhibition blockade have shown beneficial effects and many additional clinical trials targeting co-signal molecules are ongoing. The mechanisms underlying these successful treatments are explained and the future therapeutic potential in the aforementioned diseases is evaluated. Co-signal Molecules in T Cell Activation will be a valuable reference guide to co-stimulation for basic and clinical researchers in the fields of both immunology and pharmaceutical science.
Download or read book CD4 CD25 Regulatory T Cells Origin Function and Therapeutic Potential written by B. Kyewski and published by Springer Science & Business Media. This book was released on 2006-01-09 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vertebrate immune system defends the organism against invading pathogens while at the same time being self-tolerant to the body’s own constituents thus preserving its integrity. Multiple mechanisms work in concert to ensure self-tolerance. Apart from purging the T cell repertoire from auto-reactive T cells via negative selection in the thymus dominant tolerance exerted by regulatory T cells plays a major role in tolerance imposition and maintenance. Among the various regulatory/suppressive cells hitherto described, CD4+CD25+ regulatory T cells (Treg) and interleukin-10 producing T regulatory 1 (Tr1) cells have been studied in most detail and are the subject of most articles in this issue. Treg, also called "natural" regulatory T cells, will be traced from their intra-thymic origin to the site of their action in peripheral lymphoid organs and tissues. The repertoire of Treg is clearly biased towards recognition of self-antigens, thereby potentially preventing autoimmune diseases such as gastritis and oophoritis. Regulatory T cells, however also control infections, allergies and tolerance to transplanted tissues and this requires their induction in the periphery under conditions which are not yet fully understood. The concept of dominant tolerance, by far not novel, will offer new insights and hopefully tools for the successful treatment of autoimmune diseases, improved cancer immunotherapy and transplant survival. The fulfillment of these high expectations will, however, require their unambiguous identification and a better understanding of their mode of action.
Download or read book Immune Regulation written by Marc Feldmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leukocyte culture conferences have a long pedigree. This volume records some of the scientific highlights of the 16th such annual con ference, and is a witness to the continuing evolution and popularity of leukocyte culture and of immunology. There is strong evidence of the widening horizons of immunology, both technically, with the obviously major impact of molecular biology into our understanding of cellular processes, and also conceptually. Traditionally, the 'proceedings' of these conferences have been published. But have the books produced really recorded the major part of the conference, the informal, friendly, but intense and some times heated exchanges that take place between workers in tackling very similar problems and systems and which are at the heart of every successful conference? Unfortunately this essence cannot be incorpo rated by soliciting manuscripts. For this reason, we have changed the format of publication, retaining published versions of the symposium papers, but requesting the workshop chairmen to produce a summary of the major new observations and areas of controversy highlighted in their sessions, as a vehicle for defining current areas of interest and debate. Not an easy task, as the workshop topics were culled from the abstracts submitted by the participants, rather than being on predefined topics. The unseasonal warmth in Cambridge was reflected in the atmos phere of the conference, the organization of which benefited from the administrative skills of Jean Bacon, Philippa Wells, Mr. Peter Irving, and Mrs.

Download or read book Principles of Cancer Biotherapy written by Robert K. Oldham and published by Springer Science & Business Media. This book was released on 2009-08-29 with total page 743 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the time of the first edition of Principles of Cancer Biotherapy in 1987, this book represented the first comprehensive textbook on biological therapy. In 1991, when the second edition was published, there was still some doubt on the part of many oncologists and cancer researchers as to the therapeutic value of these new approaches. By 2003 and the fourth edition, it was generally agreed that biopharmaceuticals were producing major opportunities for new cancer therapies. Cancer biotherapy has now truly matured into the fourth modality of cancer treatment. This fifth revised edition describes the tremendous progress that has been made in recent years using biologicals in cancer treatment. This book summarizes an evolving science and a rapidly changing medical practice in biotherapy. In this new millennium, it is now possible to envision a much more diversified system of cancer research and treatment that will afford greater opportunities for a patient’s personalized cancer treatment. This was first envisioned in the 1987 initial edition of this textbook and is now a “new” and popular approach to cancer treatment. Some forms of cancer biotherapy use the strategy of tumor stabilization and control through continued biological therapy, akin to the use of insulin in the treatment of diabetes. This textbook illustrates new methods of thinking and new strategies for control of cancer. It is always difficult to move from past dogma to future opportunity, but this fifth edition of Principles of Cancer Biotherapy illustrates why it is so important to the patients for researchers and clinicians to explore and quickly apply these new opportunities in cancer biotherapy.

Download or read book Innovative Medicine written by Kazuwa Nakao and published by Springer. This book was released on 2015-10-13 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to innovative medicine, comprising the proceedings of the Uehara Memorial Foundation Symposium 2014. It remains extremely rare for the findings of basic research to be developed into clinical applications, and it takes a long time for the process to be achieved. The task of advancing the development of basic research into clinical reality lies with translational science, yet the field seems to struggle to find a way to move forward. To create innovative medical technology, many steps need to be taken: development and analysis of optimal animal models of human diseases, elucidation of genomic and epidemiological data, and establishment of “proof of concept”. There is also considerable demand for progress in drug research, new surgical procedures, and new clinical devices and equipment. While the original research target may be rare diseases, it is also important to apply those findings more broadly to common diseases. The book covers a wide range of topics and is organized into three complementary parts. The first part is basic research for innovative medicine, the second is translational research for innovative medicine, and the third is new technology for innovative medicine. This book helps to understand innovative medicine and to make progress in its realization.

Download or read book Protein Kinase mediated Decisions Between Life and Death written by Ayse Basak Engin and published by Springer Nature. This book was released on 2021-02-04 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein phosphorylation via protein kinases is an inevitable process that alters physiological and pathological functions of the cells. Thus, protein kinases play key roles in the regulation of cell life or death decisions. Protein kinases are frequently a driving factor in a variety of human diseases including aging and cellular senescence, immune system and endothelial dysfunctions, cancers, insulin resistance, cholestasis and neurodegenerative diseases, as well as bacterial resistance in persistent infections. Recent developments in quantitative proteomics provide important opinions on kinase inhibitor selectivity and their modes of action in the biological context. Protein Kinase-mediated Decisions Between Life and Death aims to have the reader catch insights about up-to-date opinions on “Protein Kinases” related pathways that threaten human health and life. As “Protein Kinases” are related to many health problems, clinicians, basic science researchers and students need this information.

Download or read book Kuby Immunology written by Jenni Punt and published by Macmillan Higher Education. This book was released on 2018-10-16 with total page 2997 pages. Available in PDF, EPUB and Kindle. Book excerpt: Janis Kuby’s groundbreaking introduction to immunology was the first textbook for the course actually written to be a textbook. Like no other text, it combined an experimental emphasis with extensive pedagogical features to help students grasp basic concepts. Now in a thoroughly updated new edition, Kuby Immunology remains the only undergraduate introduction to immunology written by teachers of the course. In the Kuby tradition, authors Jenni Punt, Sharon Stranford, Patricia Jones, and Judy Owen present the most current topics in an experimental context, conveying the excitement of scientific discovery, and highlight important advances, but do so with the focus on the big picture of the study of immune response, enhanced by unsurpassed pedagogical support for the first-time learner. Punt, Stranford, Jones, and Owen bring an enormous range of teaching and research experiences to the text, as well as a dedication to continue the experiment-based, pedagogical-driven approach of Janis Kuby. For this edition, they have worked chapter by chapter to streamline the coverage, to address topics that students have the most trouble grasping, and to continually remind students where the topic at hand fits in the study of immunology as a whole.
