Novel Angiogenic Mechanisms
New experimental observations often require fresh concepts for their interpretation, and at times even changes of paradigms. This is the situation with the recent realization that circulating endothelial progenitor cells may have an important contribution to the maintenance and formation of new endothelium in adult organisms, in a surprisingly wide variety of situations. The classical paradigm of angiogenesis, centered on the notion of "sprouting" can hardly accommodate them. It was previously realized that it needs to be "stretched out" to include alternative mechanisms of microvascular development, such as intussusception and capillary fusion. However, a major debate where to reconsider th...
Methods in Endothelial Cell Biology
Endothelial cell biology has developed into a vibrant discipline and has become a critical instrument to study several disease processes on the cellular and molecular level. It is now widely recognized that dysfunctions of normal endothelial cell homeostasis are involved in some of the most important human diseases, including ischemic heart diseases, hypertension, atherosclerosis, tumors, diabetes, arthritis, and inflammation. Further, the increasing importance and recognition of the field of vascular biology in general requires in vitro and in vivo techniques in order to address the complex questions. Methods in Endothelial Cell Biology is a comprehensive practical "how-to"-guide summarizing the most relevant established techniques as well as a number of new emerging techniques. Easy-to-follow reliable protocols provide a useful lab bench resource for the experienced researcher and newcomer to the field.
Leukocyte Trafficking
Written by known specialists in the field, this is a comprehensive and timely overview of a central and expanding topic. Simultaneously an introduction and a description of the latest concepts, findings and methods, the handbook provides basic knowledge on technical issues required for those intending to research in the field. It covers the functional role of involved molecules and the cellular mechanisms, and addresses selected examples for their possible application in therapy -- bridging the gap between trafficking mechanisms and novel therapeutic strategies. In addition, it includes selection of proven and timesaving methods for studying cell trafficking in vitro and in vivo. The accompanying CD-ROM makes leukocyte migration videos available to a broad audience for the first time.
Vascular Inflammation in Systemic Autoimmunity
Plasticity and dynamism characterize the immune system as a tissue-integrating network with defensive functions. Blood and lymphatic vessel trees constitute the most evident and intuitive physical platform for the development of the net of interactions between immune cells, body tissues and foreign agents. Moreover vessel repair and immune patrolling are intimately linked physiological functions with common evolutionary roots. Not surprisingly variable degrees of vascular inflammation are often detectable in the setting of systemic inflammation and autoimmunity, whereas research in the field of cardiovascular pathology is progressively converging towards the identification of a common inflammatory background. The definition of the role of vascular inflammation in causing, sustaining and/or predicting the development of systemic autoimmunity constitute a challenging, unexplored frontier towards the development of a new generation of treatments and a better patient care.
The role of arginase in endothelial dysfunction
In recent years, an increasing number of manuscripts have been published addressing the deleterious role of arginase in endothelial dysfunction. ROS have been shown to play a crucial role in arginase activation, which in turn leads to eNOS dysfunction.
Immune Dysfunction: An Update of New Immune Cell Subsets and Cytokines in Sepsis
description not available right now.
Clinical Applications of Cytokines
The driving force for research on cytokines has always been their clinical promise. Their biological properties suggested a key role in hematopoiesis, immunity, tumor genesis, hemostasis, vascularization, repair of connective tissues and integration of the immune system with the neuroendocrine system. Animal studies have shown that cytokines could be used as effective biotherapeutics with easily manageable and reversible toxicities. Clinical trials have confirmed these findings, culminating in the licensing of a number of the cytokines such as interferon alpha, interferon gamma, interleukin 2, erythropoietin, granulocyte colony stimulating factor, and granulocyte-macrophage colony stimulatin...
Cytokines and Cytokine Receptors
The field of cytokine research is expanding at a rapid pace Contributions from the major leading groups in the world on the structure and biological properties of cytokine and cytokine receptors, as well as integrated reviews on cytokines in various physiological and pathological conditions were presented in three issues of International Reviews of Immunology This collection of articles provided a unique source of information However, important discoveries are emerging very rapidly and some of the reviews written in 1997 are already outdated In this book, the editors assemble reviews that have been updated by their authors to include all the recent publications and unpublished data from the authors' laboratories This volume should serve as an excellent reference source for all those concerned by the multiple faces of cytokines in basic research and in the clinic
Perspectives on Lung Endothelial Barrier Function
Covers endothelial biology from the fundamentals of structure and lung fluid balance physiology to descriptions of the molecular mechanisms involved in the development of lung failure. This illustrated text provides the knowledge of endothelial function, vascular integrity, pulmonary function, and pathophysiology in respiratory failure.
New Approach Methods in Immunology
Currently, the assessment of functional immunological relevance is mainly done in animal models. Motivation to work on non-animal methods, or new approach methods (NAM), stems from economical and ethical considerations, and is supported by public pressure. Importantly, the translational gap between results obtained in animal studies and clinical trials in humans (the ‘valley of death’), combined with the reproducibility crisis in science, also provide strong scientific arguments to work on novel, robust, human-based methodology. The field of immunology confronts NAM scientists with specific challenges. Firstly, immunological responses require several cell types in different locations for...
