This book was released on 2014-07-08 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most interesting issues in immunology is how the innate and adaptive branches of the immune system cooperate in vertebrate organisms to respond and destroy invading microorganisms without destroying self-tissues. More than 20 years ago, Charles Janeway proposed the innate immune recognition theory [1]. He hypothesized the existence of innate receptors (Pattern recognition receptors, PRRs) that, by recognizing molecular structures associated to pathogens (PAMPs) and being expressed by antigen presenting cells (APCs) and epithelial cells, could alert the immune system to the presence of a pathogen, making it possible to mount an immediate inflammatory response. Moreover, by transducing the alert signal in professional APCs and inducing the expression of costimulatory molecules, these receptors could control the activation of lymphocytes bearing clonal antigen-specific receptors, thereby promoting appropriate adaptive immune responses. Since adaptive immunity can be activated also following sterile inflammatory conditions, it was subsequently proposed by Polly Matzinger that the innate immune system could be also activated by endogenous danger signals, generically called danger associated molecular patterns (DAMPs)[2]. The first prediction has been amply confirmed by the discovery of Toll-like receptors [3; 4; 5] and cytoplasmic PRRs such as RIG-like receptors [6]. Other PRR families such as the NOD-like receptors and C-type lectins exert immunogenic or tolerogenic signals [7; 8; 9] and may recognize not strictly pathogens but also endogenous danger signals that may lead to inflammasome activation [10; 11] . Dendritic cells (DCs) have been identified as the cells of the innate immune system that, by sensing PAMPs or DAMPs transduce signals to the nucleus. This leads to a transcriptional reprogramming of DCs with the consequent expression of three signals, namely signal 1 (MHC+peptide), signal 2 (surface costimulatory molecules) and signal 3 (cytokines) necessary for the priming of antigen-specific naïve T cell responses (signal 1 and 2) and T cell polarization (signal 3). The reason why DCs are superior with respect to other professional APCs in naïve T cell activation has not been unequivocally defined but in vivo may mainly result from their migration capacity to secondary lymphoid organs. It has not been established whether DCs can provide a special “signal 2” or simply very high levels, compared with other APCs, of commonly expressed signals 1 and 2, so that a naïve T cell could reach the threshold of activation. A second aspect of DC biology needs also to be taken into account. Concerning the question of how self-tissues are not destroyed following the initiation of adaptive immune responses, different mechanisms of central and peripheral auto-reactive T cell tolerization have been proposed [12]. In particular, it has been defined that high affinity T cells are deleted in the thymus, while low affinity auto-reactive T cells or T cells specific for tissue-sequestered antigens that do not have access to the thymus are controlled in the periphery. In a simplified vision of how peripheral T cell tolerance could be induced and maintained, it was thought that, in resting conditions, immature DCs, expressing low levels of signal 1 and low or no levels of signal 2, were able to induce T cell unresponsiveness. Nevertheless, it is now clear that a fundamental contribution to the peripheral tolerance is due to the conversion of naïve T cells into peripheral regulatory T cells (pTreg cells) and it is also clear that DCs need to receive a specific conditioning to become able to induce pTreg cell differentiation. Even more intriguing is that also DCs activated through PRRs, with particular Toll like receptor (TLR) agonists, are capable of generating pTreg cell conversion if these agonists induce the production of the appropriate cytokines.

Download or read book Dendritic Cell Control of Immune Responses written by Penelope Anne Morel and published by Frontiers Media SA. This book was released on 2016-07-27 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dendritic cells (DC) are among the first cells to encounter pathogens and damage in peripheral tissues and, upon activation, DC migrate to lymph nodes where they activate and educate T cells to initiate and shape the immune response. DC present pathogen-derived antigen to T cells and drive T cell differentiation into particular effector cells through the expression and secretion of co-stimulatory molecules and cytokines respectively. The study of DC biology has included the identification of multiple DC subsets in tissues and lymphoid organs, the differentiation and plasticity of DC subsets, the functional consequences of DC interaction with pathogen, control of DC migratory properties and the impact of DC on T cell activation and differentiation. In recent years sophisticated systems biology approaches have been developed to deepen our understanding of DC function. These studies have identified differences between DC subsets located in various tissues and critical factors that drive the outcome of the interaction between DC and T cells. DC are currently being used in in various clinical therapeutic settings, including as vaccines for cancer and autoimmune disease. A clear understanding of DC factors that contribute to specific immune responses is vital to the success of DC based therapies. This research topic will give a comprehensive overview of current issues in DC biology and provides an update on the clinical uses of DC in the therapy of autoimmunity and cancer.

Download or read book Emerging Concepts Targeting Immune Checkpoints in Cancer and Autoimmunity written by Akihiko Yoshimura and published by Springer. This book was released on 2017-11-25 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews the current state of research on immune checkpoints and offers novel concepts. It discusses the two most important immune checkpoints: T lymphocyte-associated antigen-4 (CTLA-4) and programmed cell death-1 (PD-1). It shows that antagonistic antibodies against these two molecules are highly effective in the treatment of various cancers and that PD-1 and CTLA-4 have been linked to the suppression of T-cell receptor signaling and co-stimulatory molecules. Further, the volume examines other agents, a number of cells, receptors and signaling molecules, that are also involved in the regulation of T-cell activation and extends the concept of immune checkpoints to “molecules and cells that negatively regulate T-cell activation”. Playing essential roles in immune homeostasis, they could offer new targets for cancer immunotherapy, and for the therapy of autoimmune diseases. Written by internationally respected scientists, this book will appeal to basic scientists, clinicians, drug development researchers, and advanced students alike.

Download or read book Cancer Immunotherapy Mechanisms of Cancer Immunity Engineering Immune Based Therapies and Developing Clinical Trials written by Jianxun Song and published by Bentham Science Publishers. This book was released on 2015-04-16 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clinicians, patients and scientists, alike, have been battling cancer for over several decades; however, patient outcomes have not significantly improved over the years with conventional therapies. In recent years, this has caused researchers to look for a change in the status quo, and, the awareness of the human immune system, which has an intrinsic mechanism to control microbial pathogens and dysfunctional self-tissues, has triggered scientists to look for new modes of cancer therapy. Cancer Immunotherapy has become a major research field as a result of these efforts, gaining some recognition for notable breakthroughs in cancer patient prognosis. Frontiers in Cancer Immunology collectively presents the methods which have been studied and used in cancer immunotherapy based on the different components of human immune system. The series will give clinicians and immunologists a roadmap of current trends in all branches of cancer immunology. This volume lists the major immune system components (such as T cells and NK cells and associated antigens/antibodies) which have been demonstrated to limit the growth of or kill tumor cells. Relevant applications in cancer therapy are also included in addition to a general introduction to engineered as well as targeted cancer immunotherapies (cancer vaccines).
