Available in PDF, EPUB and Kindle. Book excerpt: Mammalian pregnancy represents a unique immunological riddle in that the mother does not reject her allogeneic fetus. In part this is largely due to a general sequestration or diminution of T cell activity, and an increased involvement of the innate immune system. The field of immunology is concerned primarily with how innate and adaptive mechanisms collaborate to protect vertebrates from infection. Although many cellular and molecular actors have evidently important roles, antibodies and lymphocytes are considered to be the principal players. Yet despite their importance, it would be definitely simplistic to conclude that they are solely essential for immunity overall. A major distinction between adaptive and innate immunity is the spontaneity of the innate immune response, which utilizes an already pre-existing but limited repertoire of responding modules. The slower onset of adaptive immunity compensates by its ability to recognize a much broader repertory of foreign substances, and also by its power to constantly improve during a response, whereas innate immunity remains relatively unaffected. The interactions between the reproductive system and the immune system are of particular interest, since the reproductive system is unique in that its primary role is to assure the continuity of the species, while the immune system provides internal protection and thus facilitates continued health and survival. The modus operandi of these two morphologically diffuse systems involves widely distributed chemical signals in response to environmental input, and both systems must interact for the normal functioning of each. Furthermore, dysregulation of normal physiological interactions between the reproductive and immune systems can lead to severe pregnancy-related disorders or complications. On the other hand, by ameliorating auto-inflammatory conditions such as MS and RA, pregnancy may provide a unique insight into novel immune modulatory strategies. The scientific focus on reproductive–immune research has historically provided substantial insight into the interface between these two physiological systems. A translational research approach would involve a tight interaction between diverse scientific and clinical disciplines including immunology, obstetrics, haematology, haemostasis and endocrinology. With so much recent progress in the field, we believe that it is valuable and well-timed to review the broad variety of the relevant physiologic and pathologic aspects – from menstruation to fertilization and implantation, and from placentation and pregnancy per se to the post partum condition - in which the immune system takes part. We are looking forward to a wide and vivid discussion of these and related issues, and we sincerely expect that our readers profoundly benefit from new exciting insights and fruitful collaborations.

This book was released on 2012-12-06 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to describe the nature of the materno-fetal immunobiological relationship and to suggest the direction in which the management of reproduction and its failure in man is moving. The several authors, who have written about their special fields of interest, need to be read within a framework designed to blend their contributions into a whole. This preamble provides a part of that framework, by describing the early development of the embryo, that of the placenta and its membranes and their anatomical relationship with maternal tissues: in other words, the stage upon which this materno-fetal dialogue takes place. Professor Maureen Young's 'tour de force', encapsulating the whole of fetal physiology into a single chapter, completes the background information. After Maureen Young's summary of fetal physiology, Matteo Adinolfi describes the development of the immune system in the fetus, including new information that allows more accurate speculation concerning the gestational age at which fetal immune responses of various kinds may begin. Charles Loke examines the nature of antigens which are found in the placenta, concentrating on those which occur on syncytiotrophoblast and suggesting roles for them in fetal development. Arnold Klopper covers the wide range of proteins and hormones which have been studied during pregnancy and found to vary in a potentially significant way. He has been careful to distinguish between observation and hypothesis, as far as any immunomodulating action is concerned, and his analysis is a model of scientific scepticism.
Download or read book Principles and Practice of Maternal Critical Care written by Sharon Einav and published by Springer Nature. This book was released on 2020-11-25 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book contains a collection of the most recent insights regarding maternal morbidity and mortality and optimization of the care processes during acute critical illness. The volume represents a practical resource to be used in real-time by medical practitioners faced with a woman who is critically ill during pregnancy and the peripartum period. By providing concise tools for disease identifiers and management flow-charts, the Editors aimed to increase awareness and improve processes of care for this population. Many care paradigms for obstetric patients are currently unstandardized, unfocused and often do not follow a pre-determined path. Each chapter will provide the practitioner with updated information on how to identify specific critical conditions and how to manage them once they have been identified, to enhance recognition and readiness. This book should be used as a resource to improve the quality of care administered to obstetric patients, to reduce fragmented care processes and to improve interdisciplinary co-ordination and communication, with the overall aim of decreasing maternal morbidity and mortality. Therefore, this book represents an invaluable guide to specialists in critical care, anesthesia and obstetrics as well as to intensive care nurses and midwives."

Download or read book Effects of Pregnancy and Hormones on T cell Immune Regulation in Multiple Sclerosis written by Sandra Hellberg and published by Linköping University Electronic Press. This book was released on 2019-10-22 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple sclerosis (MS) is characterized by a dysregulated immune system leading to chronic inflammation in the central nervous system. Despite increasing number of treatments, many patients continue to deteriorate. A better understanding of the underlying disease mechanisms involved in driving disease is a pre-requisite for finding new biomarkers and new treatment targets. The improvement of MS during pregnancy, comparable to the beneficial effects of the most effective treatment, suggests that the transient and physiological immune tolerance established during pregnancy could serve as a model for successful immune regulation. Most likely the immune-endocrine alterations that take place during pregnancy to accommodate the presence of the semi-allogenic fetus contribute to the observed disease improvement. The aim of this thesis was to characterize the dysregulated immune system in MS and define potential factors and mechanisms established during pregnancy that could be involved in the pregnancy-induced effects in MS, focusing on CD4+ T cells as one of the main drivers in immunity and in the MS pathogenesis. Using a network-based modular approach based on gene expression profiling, we could show that CD4+ T cells from patients with MS displayed an altered dynamic gene response to activation, in line with a dysregulated immune system in MS. The resulting gene module disclosed cell activation and chemotaxis as central components in the deviating response, results that form a basis for further studies on its modulation during pregnancy. Moreover, a combination of secreted proteins (OPN+CXCL1-3+CXCL10-CCL2), identified from the module, could be used to separate patients and controls, predict disease activity after 2 years and discriminate between high and low responders to treatment, highlighting their potential use as biomarkers for predicting disease activity and response to treatment. The pregnancy hormone progesterone (P4), a potential factor involved in the pregnancy-induced amelioration of MS, was found to significantly dampen CD4+ T cell activation. Further detailed transcriptomic profiling revealed that P4 almost exclusively down-regulated immune-related pathways in activated T cells, several related to or downstream of T cell activation such as JAKSTAT signaling, T cell receptor signaling and cytokine-cytokine receptor interaction. In particular, P4 significantly affected genes of relevance to diseases known to be modulated during pregnancy, where genes associated to MS were most significantly affected, supporting a role for P4 in the pregnancy-induced immunomodulation. By using another approach, the role of thymus in T cell regulation during pregnancy was assessed. Two established measures of thymic output, CD31 expression and TREC content, were used and showed that thymic output of T cells is maintained during human pregnancy, or even possibly increased in terms of regulatory T cells. This thesis further supports a pivotal role for CD4+ T cells and T cell activation in the MS pathogenesis and adds to the knowledge of how they could be involved in driving disease. We identified a novel strategy for capturing central aspects of the deviating response to T cell activation that could be translated into potentially clinically relevant biomarkers. Further, P4 is emerging as a promising candidate for the pregnancy-induced immunomodulation that could be of importance as a future treatment option. Lastly, maintained thymic output of T cells during human pregnancy challenges the rodent-based dogma of an inactive thymus during pregnancy. Thymic dysfunction has been reported not only in MS but also in rheumatoid arthritis, another inflammatory disease that improves during pregnancy, which highlights a potential role for thymus in immune regulation that could be involved in the pregnancy-induced amelioration.
Download or read book Immunology of Pregnancy 2013 written by Gérard Chaouat and published by Bentham Science Publishers. This book was released on 2013-11-08 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since a September, 1992, Nature article which read: “Can there be life without LIF?”, researchers now realize that the maternal immune system is both a foe (it can reject the conception) and a friend (immune cells and molecules are also necessary for successful pregnancy). Leukemia Inhibitory Factor (LIF) when absent, prevents embryo implantation in rodents. From fecundation to parturition, immunity acts as a Janus, required but potentially dangerous. However, the complexity and the diversity of immunity in pregnancy deters many from entering the field. This book will try to give a complete overview of immunity from gametes till parturition, in brief, but with complete chapters and subsections, each written by specialists in the field. The importance of the topic relies not only on “the riddle of the fetal allograft”, which is per se fascinating, but on its consequences, linked to the development of IVF and in general, Assisted Reproductive Technologies (ART) / Medicine. Since the discovery that there would not be (mammalian) life without LIF, it has become clear that Immune Molecules, and in general, transient post mating inflammatory reactions are required for successful implantation. Disruptions of this process can lead to implantation failure / sterility. In later stages of pregnancy immunological cells, mostly of the innate immune system, control formation of local spiral arteries. Finally, a state of tolerance establishes itself, whose “break’ leads to immune abortion and the vascular bed is further transformed and enlarged, till delivery, and here again “immunological cytokines” do play a major role and can eventually cause immune mediated abortion. Failure of, not just, the cytokine and cell recognition mediated dialogue, but also the pre and peri-implantation “preparation of the uterus”, as stated, leads to sterility, early pregnancy loss and recurrent abortions. There is also an increasingly stronger argument to implicate immunology in pre-eclampsia. Further still, immunology is also implicated in the control of local infection, mother to child transmission of pathogens (notably, but not limited to, HIV). Finally, pregnancy is the only known physiological phenomenon where the once named “suppressor T cells,” re-emerge as “regulatory T cells”, and play a cardinal role. This E-book provides a complete compendium of gynecological immunology, spanning from fecundation to delivery. Topics also include the role of various cell types (such as T regs ad NK cells) in implantation and uterine changes as well as the genetic regulation of immunological processes. As such it will be of interest not only to fundamental and reproductive immunologists, but more importantly, clinicians in obstetrics and gynecology.

Available in PDF, EPUB and Kindle. Book excerpt: Chesley’s Hypertensive Disorders in Pregnancy continues its tradition as one of the beacons to guide the field of preeclampsia research, recognized for its uniqueness and utility. Hypertensive disorders remain one the major causes of maternal and fetal morbidity and death. It is also a leading cause of preterm birth now known to be a risk factor in remote cardiovascular disease. Despite this the hypertensive disorders remain marginally studied and management is often controversial. The fourth edition of Chesley’s Hypertensive Disorders in Pregnancy focuses on prediction, prevention, and management for clinicians, and is an essential reference text for clinical and basic investigators alike. Differing from other texts devoted to preeclampsia, it covers the whole gamut of high blood pressure, and not just preeclampsia. Features new chapters focusing on recent discoveries in areas such as fetal programming, genomics/proteomics, and angiogenesis Includes extensive updates to chapters on epidemiology, etiological considerations, pathophysiology, prediction, prevention, and management Discusses the emerging roles of metabolic syndrome and obesity and the increasing incidence of preeclampsia Each section overseen by one of the editors; each chapter co-authored by one of the editors, ensuring coherence throughout book
