Book Description
A complex exchange of signals between endothelial cells and tissues occurs during steady-state and in inflammatory conditions. These interactions involve numerous cell types including an active contribution from endothelial cells and occur on both sides of the endothelial monolayer. In addition to functioning as selective permeability barriers, it is increasingly recognized that local cell attraction to endothelial cells provides the potential for focal interactions between relevant cells. In this context, cellular interactions taking place at the surface of the endothelium and within the perivascular spaces are thought to initiate crucial steps in the generation and shaping of immune responses. Blood elements (such as leukocytes, platelets, and vesicles) converge to the barrier formed by the endothelium where perivascular (such as macrophages, pericytes) initiate, convey, and/or amplify signals revealing tissue status. The innate and adaptative functions of endothelial cells themselves together with the immune functions of assembled cells at a focal point in capillaries create the potential for exchange of signals and dynamic fine tuning of responses through cell programming and cell selection. The resulting immune response may range from inadequate immunity and/or exhaustion to excess tissue destruction and fibrosis. Productive inflammation and its resolution are critically reliant on which cells are recruited and in which order, their state of activation, and interactions between recruited cells. Tissue-dependent signals further shape the recruitment of leukocytes to the endothelium. In the kidney for instance, in the presence of immune complexes, perivascular resident macrophages located in subendothelial spaces coupled with endothelial cells induce monocyte and neutrophil tissue infiltration, operating therefore as an anatomical and functional unit. The goals of this Research Topic are (i) to analyze how signal integration and partnering of cell types in transendothelial migration contribute to the development of tissue inflammation and how responses are geared towards specific profiles of reactions to injury; (ii) how the interplay between cell types including, but not limited to, endothelial cells, monocytes, resident macrophages, and T and B cells dynamically governs the immune responses that take place in the tissue; (iii) in which way do integrative capacities of endothelial and subendothelial cells shape and coordinate the successive recruitment of leukocyte populations.

Book Description
Arrest chemokines are a small group of chemokines that promote leukocyte arrest from rolling by triggering rapid integrin activation. Arrest chemokines have been described for neutrophils, monocytes, eosinophils, naïve lymphocytes and effector memory T cells. Most arrest chemokines are immobilized on the endothelial surface by binding to heparin sulfate proteoglycans. Whether soluble chemokines can promote integrin activation and arrest is controversial (Alon-Gerszten). Many aspects of the signaling pathway from the GPCR chemokine receptor to integrin activation are the subject of active investigation. Leukocyte adhesion deficiency III is a human disease in which chemokine-triggered integrin activation is defective because of a mutation in the cytoskeletal protein kindlin-3. About 10 different such mutations have been described. The defects seen in patients with LAD-III elucidate the importance of rapid integrin activation for host defense in humans. We welcome reports that help clarifying this crucial first step in the process of leukocyte transendothelial migration.

Book Description
The vascular endothelium lining the inner surface of blood vessels serves as the first interface for circulating blood components to interact with cells of the vascular wall and surrounding extravascular tissues. In addition to regulating blood delivery and perfusion, a major function of vascular endothelia, especially those in exchange microvessels (capillaries and postcapillary venules), is to provide a semipermeable barrier that controls blood–tissue exchange of fluids, nutrients, and metabolic wastes while preventing pathogens or harmful materials in the circulation from entering into tissues. During host defense against infection or tissue injury, endothelial barrier dysfunction occurs as a consequence as well as cause of inflammatory responses. Plasma leakage disturbs fluid homeostasis and impairs tissue oxygenation, a pathophysiological process contributing to multiple organ dysfunction associated with trauma, infection, metabolic disorder, and other forms of disease. In this book, we provide an updated overview of microvascular endothelial barrier structure and function in health and disease. The discussion is initiated with the basic physiological principles of fluid and solute transport across microvascular endothelium, followed by detailed information on endothelial cell–cell and cell–matrix interactions and the experimental techniques that are employed to measure endothelial permeability. Further discussion focuses on the signaling and molecular mechanisms of endothelial barrier responses to various stimulations or drugs, as well as their relevance to several common clinical conditions. Taken together, this book provides a comprehensive analysis of microvascular endothelial cell and molecular pathophysiology. Such information will assist scientists and clinicians in advanced basic and clinical research for improved health care.

Book Description
The development and function of the immune system is dependent on interactions between haematopoietic cells and non-hematopoietic stromal cells. The non-hematopoietic stromal cells create the microenvironment in which the immune system operates, providing an architectural landscape for hematopoietic cell-cell interactions and molecular cues governing haematopoietic cell positioning, growth and survival. Not surprisingly, therefore, aberrant stromal cell function has recently been shown to play a key role in the development of disease pathologies associated with immune dysfunction. For example, remodelling of lymphoid tissue stroma and the development of ectopic tertiary lymphoid tissues are characteristic of many infectious and inflammatory diseases and stromal cells have a recognised role in lymphoma and tumour development and resistance to therapy. An increased understanding of the molecular basis of stromal cell differentiation and function in these varied contexts will provide new tools to promote research on stromal cell biology and immune dysfunction, and potential new targets for therapeutic intervention in diseases with a major impact on public health. The importance of stromal cells and the molecular mechanisms of stromal cell function in the regulation of immune responses have only recently been appreciated and thus represent an exciting new area in immunology.

Book Description
The endothelium enables communication between blood and tissues and is actively involved in cardiovascular homeostasis. Endothelial dysfunction has been recognized as an early step in the development of cardiovascular diseases: respectively, endothelium represents a potential therapeutic niche with multiple targets. The purpose of the book is to point out some recent findings of endothelial physiology and pathophysiology emphasizing various aspects of endothelial dysfunction connected to the body's internal and external environment. While basic features of the endothelium are presented in an introductory chapter, the authors of the following 17 chapters have provided extensive insight into some selected topics of endothelial (dys)function. The book would hopefully be useful for anyone interested in recapitulating endothelial (patho)physiology and expanding knowledge of molecular mechanisms involved in endothelial dysfunction, relevant also for further clinical investigations.
