This book was released on 2015-08-14 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last years, the research on extracellular vesicles (EVs) has raised giving new insights into pathophysiology of several diseases. EVs are membrane-bound particles secreted by almost all cell types. Depending on their biogenesis and size they include exosomes, microparticles / microvesicles and apoptotic bodies. Characteristically, EVs carry markers from the source cell membrane and contain genetic material, lipids and proteins inside. They are known to play a role in cell-to-cell communication and to produce genotypic and phenotypic modifications in the target cell including: antigen presentation, apoptosis induction, cellular activation, inhibition or differentiation. In particular, increasing concentrations of EVs have been found in many diseases such as cancer, autoimmune and cardiovascular diseases, among others. Most of the studies in EVs are focused on the characterization of EVs compounds, identifying mechanism of action, their potential use as biomarkers, and few of them investigate a therapeutic usage. However, there are some issues to be achieved on the path to their clinical application. This research topic offers a common place to discuss current and novel clinical applications of EVs pointing on future directions. We encouraged the submission of original articles, reviews, hypothesis, controversies, future perspectives and personal viewpoints on the following topics of interest, but not limited to: • Contribution of EVs to better understand the pathology of immunological diseases. • Standardization of isolation and quantification protocols in the daily clinical practice. • Possible applications of EVs as clinical biomarkers (diagnostic, prognostic and evolution marker). • Therapeutic role of EVs being vehicles of specific cargo: current clinical trials? • Novel immunological functions of EVs.
Book Synopsis Role of Extracellular Vesicles in Immune Regulation by : Diego Alberto Lema Rodriguez
Download or read book Role of Extracellular Vesicles in Immune Regulation written by Diego Alberto Lema Rodriguez and published by . This book was released on 2021 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immune responses require complex intercellular communication. One unique mode is by extracellular vesicles (EVs). In this dissertation, I studied the role of EVs in modulating immune responses in transplantation, autoimmunity and cancer.In transplantation, grafts can transfer HLA molecules in EVs to the recipient's antigen presenting cells (APCs). These "cross-decorated" APCs present the allo-HLA to effector T cells. Non-inherited maternal antigens (NIMA) are inherently tolerogenic during pregnancy and throughout life, and grafts that express NIMA are less prone to chronic rejection. I investigated the cross-decoration of fetal cord blood cells with NIMA in utero. I found that half of human pregnancies are associated with HLA-I NIMA cross-decoration of APCs, which express high levels of PD-L1, due to co-transfer of PD-L1 and of nucleic acid. Interestingly, I found that this phenomenon is recapitulated in recipients of NIMA+ grafts. These results suggest a tolerogenic mechanism to NIMA in pregnancy and transplantation. Then, I studied cross-decoration with HLA class II. I show that after receiving a HLA-DR15+ lung transplant, HLA-DR15negative recipients' immune cells responded to HLA-DR15-restricted collagen V epitopes. I observed cross-decoration of DCs with HLA-DR15 in transgenic heart mouse recipients. This work shows that HLA-II can cross-decorate DCs, and impart the host with a new repertoire of HLA class II restrictions, facilitating autoimmunity and transplant rejection. Next, I studied cytokine (IL-35) delivery by EVs. I show that IL-35 subunits are present in Treg-derived EVs. IL-35 EVs can directly suppress immune responses, but further, can coat lymphocytes with active cytokine, rendering them suppressive. This dissertation supports this as a mechanism of "infectious tolerance". Later, I investigated tumor immune escape mechanisms using the trans-vivo DTH assay. NSCLC patients' immune cells were challenged with tumor antigens in SCID mouse footpads. I identified most (8/9) patients had PD-1 dependent anergy to tumor antigens, but a minority (3/9) further had active PD-1-dependent immune regulation. This second phenotype was associated with worse outcomes. In conclusion, in this thesis I demonstrate an important immune regulatory role of EVs in transplant, autoimmunity and cancer, by transfer of HLA class I and II, cytokines and immune regulatory ligands.

Book Synopsis Role of Extracellular Vesicles on Immune Regulation in an Animal Model of Multiple Sclerosis by : Cory Willis
Download or read book Role of Extracellular Vesicles on Immune Regulation in an Animal Model of Multiple Sclerosis written by Cory Willis and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Extracellular vesicles play important and crucial roles in orchestrating and modulating cellular responses under both normal and diseased conditions. In my thesis work, I studied extracellular vesicle release from astrocytes during CNS inflammation. Moreover, I studied how extracellular vesicles can modulate and drive the immune response during active CNS disease. Extracellular vesicles encompass a heterogeneous group of cell-derived vesicles that have been found to be important in initiating and directing pathological responses. In my thesis work, I focused on the characterization and quantification of extracellular vesicles from astrocytes under normal and inflammatory conditions. As described in chapter three of my thesis, I developed a semi-quantitative flow cytometry method for analysis of extracellular vesicles from astrocytes and found that following cytokine challenge in vitro, astrocytes releases more extracellular vesicles. Additionally, I studied whether astrocyte-derived extracellular vesicles could be detected in peripheral circulation and if their numbers increased in a mouse-model of multiple sclerosis. Allowing for the potential of astrocyte-derived extracellular vesicles to be potent biomarkers to monitor disease progression. Furthermore, I studied whether extracellular vesicles could modulate the immune system during active disease. As described in chapter four, I found that injection of plasma extracellular vesicles into animals during the height of clinical disease in a mouse model of multiple sclerosis induced a relapsing-remitting phenotype that seemed to be driven by an unidentified interaction between the blood coagulation factor fibrinogen and CD8+ T cells. Additionally, post-translational modifications analysis of the proteomic content of plasma extracellular vesicles identified extensive citrullination occurs on proteins in blood plasma that may be causative in driving the immune responses observed. In general, my thesis studies focused on the characterization and effect of extracellular vesicles from a CNS-cell source and in an animal model of multiple sclerosis.
Book Synopsis The Role of Extracellular Vesicles in Immunomodulation and Pathogenesis of Leishmania and Other Protozoan Infections by : Fikrettin ≈ûahin
Download or read book The Role of Extracellular Vesicles in Immunomodulation and Pathogenesis of Leishmania and Other Protozoan Infections written by Fikrettin ≈ûahin and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extracellular vesicles (EVs) have lately emerged as crucial mediators in parasite infections. Recent research suggests that protozoan parasites, including Leishmania, employ EVs as transport vehicles to deliver biologically active effector molecules such as parasitic virulence factors to modulate the host immune system and their microenvironment. The immunomodulatory effects of EVs play an essential role in the formation and progression of parasitic diseases. The immunomodulatory strategies applied by EVs of protozoan origin have similarities to the development and progression of other infections or diseases such as cancer. In this chapter, we will provide recent insights into the role of EVs in host-pathogen interactions, intercellular-communication, immunomodulation and pathogenesis of Leishmania and other protozoan parasites, including Plasmodium spp., Toxoplasma spp. and Trypanosoma spp. In addition, biologically inspired by the immunomodulation strategies of protozoan parasites, new immunotherapeutic models are being currently investigated to implement EVs more intensively in both therapy and diagnostics. Therefore, besides highlighting the role of EVs in protozoan infections, this chapter sheds light briefly on new immunotherapeutic approaches utilizing the strategies of protozoan EVs in medicine.

Book Synopsis Mesenchymal Stem Cell Therapy by : Lucas G. Chase
Download or read book Mesenchymal Stem Cell Therapy written by Lucas G. Chase and published by Springer Science & Business Media. This book was released on 2012-12-12 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, significant efforts have been made to develop stem cell-based therapies for difficult to treat diseases. Multipotent mesenchymal stromal cells, also referred to as mesenchymal stem cells (MSCs), appear to hold great promise in regards to a regenerative cell-based therapy for the treatment of these diseases. Currently, more than 200 clinical trials are underway worldwide exploring the use of MSCs for the treatment of a wide range of disorders including bone, cartilage and tendon damage, myocardial infarction, graft-versus-host disease, Crohn’s disease, diabetes, multiple sclerosis, critical limb ischemia and many others. MSCs were first identified by Friendenstein and colleagues as an adherent stromal cell population within the bone marrow with the ability to form clonogenic colonies in vitro. In regards to the basic biology associated with MSCs, there has been tremendous progress towards understanding this cell population’s phenotype and function from a range of tissue sources. Despite enormous progress and an overall increased understanding of MSCs at the molecular and cellular level, several critical questions remain to be answered in regards to the use of these cells in therapeutic applications. Clinically, both autologous and allogenic approaches for the transplantation of MSCs are being explored. Several of the processing steps needed for the clinical application of MSCs, including isolation from various tissues, scalable in vitro expansion, cell banking, dose preparation, quality control parameters, delivery methods and numerous others are being extensively studied. Despite a significant number of ongoing clinical trials, none of the current therapeutic approaches have, at this point, become a standard of care treatment. Although exceptionally promising, the clinical translation of MSC-based therapies is still a work in progress. The extensive number of ongoing clinical trials is expected to provide a clearer path forward for the realization and implementation of MSCs in regenerative medicine. Towards this end, reviews of current clinical trial results and discussions of relevant topics association with the clinical application of MSCs are compiled in this book from some of the leading researchers in this exciting and rapidly advancing field. Although not absolutely all-inclusive, we hope the chapters within this book can promote and enable a better understanding of the translation of MSCs from bench-to-bedside and inspire researchers to further explore this promising and quickly evolving field.
Book Synopsis Immune Response Activation and Immunomodulation by : Rajeev Tyagi
Download or read book Immune Response Activation and Immunomodulation written by Rajeev Tyagi and published by BoD – Books on Demand. This book was released on 2019-04-17 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immune Response Activation and Immunomodulation has been written to address the perceived needs of both medical school and undergraduate curricula and to take advantage of new understandings in immunology. We have tried to achieve several goals and present the most important principles governing the function of the immune system. Our fundamental objective has been to synthesize the key concepts from the vast amount of experimental data that have emerged in the rapidly advancing field of immunology. The choice of what is most important is based on what is most clearly established by experimentation, what our students find puzzling, and what explains the wonderful efficiency and economy of the immune system. Inevitably, however, such a choice will have an element of bias, and our bias is toward emphasizing the cellular interactions in immune response by limiting the description of many of the underlying biochemical and molecular mechanisms to the essential facts. This book gives an insight into the role of cytokines in activating immune response during pathogenic invasion. Immunomodulation, aryl hydrocarbons, the role of the protein defensin and nucleated cells in provoking immune response, Bcl protein/gene-based apoptotic pathways, and plant-derived phytochemical-mediated immune response are all central themes of this book.
Book Synopsis Comorbidity in Rheumatic Diseases by : Yasser El Miedany
Download or read book Comorbidity in Rheumatic Diseases written by Yasser El Miedany and published by Springer. This book was released on 2017-08-24 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores comorbidity in patients with rheumatic diseases and details both care and treatment options in standard clinical practice. Patients with rheumatic diseases are clinically complex, and the interplay of their disease activity with associated conditions may lead to increased morbidity and mortality. Recently there have been major advances in the management of rheumatic diseases, however, without addressing the potential comorbid conditions, including cardiovascular disease; pulmonary disease; and depression; outcomes remain poor. With its 19 chapters, covering the management of major rheumatic diseases (e.g. rheumatoid arthritis, systemic lupus erythematosus , and osteoarthritis), potential comorbidities and treatment recommendations, as well as possible interactions between conditions; this book addresses the gap between textbook medicine and day to day patients' care. Authors also discuss the new hot issue of the comorbidity index, comparing the standard tools to the recently developed indices and how they can assist the rheumatologists in determining disease burden, prognosis, and comorbidity probability. This book is an ideal clinical guide and reference that enables rheumatologists, internal medicine physicians, and residents to address the full clinical expression of these rheumatic diseases with views towards prevention or early management of comorbid conditions.
