Download or read book Leukocyte Integrins in the Immune System and Malignant Disease written by Bernhard Holzmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most lymphocytes recirculate throughout the body, migrating from blood through organized lymphoid tissues such as lymph nodes (LN) and Peyer's patches (PP), then to lymph and back to blood (GOWANS and KNIGHT 1964). Smaller numbers of lymphocytes migrate from blood to extranodal tissues such as pancreas and then through lymphatic vessels to LN (MACKAY et al. 1990). An important feature of this migration is the ability of lymphocytes to recognize and adhere to the surface of blood vessel endothelial cells before migrating through the vessel wall into surrounding tissue (CARLOS and HARLAN 1994; IMHOF and DUNON 1995; BUTCHER and PICKER 1996). Adhesion interactions of vascular endothelium with lymphocytes under flow or shear consist of at least four steps: (I) an initial transient sticking or rolling; (2) if the lymphocytes encounter appropriate activating or chemotactic factors in the local environment, rolling may be followed by a lymphocyte activation step that then leads to; (3) strong adhesion or sticking that may be followed by; (4) lym phocyte diapedesis into tissue (BUTCHER 1991; SHIMUZU et al. 1992; SPRINGER 1994; BARGATZE et al. 1995). Specific lymphocyte and endothelial adhesion molecules (AM) are involved in each step of this "adhesion cascade" (reviewed in CARLOS and HARLAN 1994; IMHOF and DUNON 1995; BUTCHER and PICKER 1996). This allows lymphocyte migration to be controlled at several different steps, leading to a combinatorial increase in specificity and sensitivity.
Download or read book Adhesion in Leukocyte Homing and Differentiation written by Dominique Dunon and published by Springer. This book was released on 2012-01-06 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of Current Topics in Microbiology and Immunology was planned in parallel with an EM BO workshop on cell-cell Interactions in Leukocyte Homing and Differentiation held at the Basel Institute for Immunology in November 1992, and many of the workshop speakers have contributed to it. Cell adhesion is one of the most dynamic fields of biological research and presented in this book is the current knowledge on the structure and function of the major families of cell adhesion molecules-the integrins, the selectins, the immunoglobulin superfamily, and CD44. Complex interactions between the members of these families mediate diverse adhesion functions, including leukocyte-leukocyte interactions, lymphocyte homing, inflammation, and lymphocyte-stromal cell interaction during hematopoiesis. A great deal of emphasis is placed on the regulatory elements that control the expression and function of adhesion molecules. Cytokines not only induce the expression of certain adhesion molecules, but may also modify their functional status. For instance, the integrins exist in either an inactive nonfunctional form or an active functional form, and a number of intracellular or extracellular stimuli modify integrin function. This is particularly important during leukocyte binding to endothelium and transendothelial migration, which proceeds through a cascade of adhesion events. Although cell adhesion molecules play an important role in many processes, this book concentrates on their role within the immune system. A number of chapters discuss the migration of lymphocytes between hematopoietic organs such as the thymus, lymph nodes, Peyer's patches, and spleen.
Download or read book Jaagsiekte Sheep Retrovirus and Lung Cancer written by Hung Y. Fan and published by Springer. This book was released on 2002-12-13 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Retroviruses have been of great importance to biomedical science for the past half century. Initially, studies on oncogenic animal retroviruses provided important insights into molecular processes in carcinogenesis – most notably the existence and mechanisms of action of oncogenes and proto-oncogenes. Moreover, several human diseases are caused by retroviruses, including AIDS, adult T-cell leukemia and the neurological disease HAM/TSP. The topic of this volume is a relatively unknown animal retrovirus, jaagsiekte sheep retrovirus, the causative agent of transmissible lung cancer in sheep –ovine pulmonary adenocarcinoma. The disease was first documented in South Africa in the 1800s, it has a wide geographical distribution, and it is of economic importance in high endemic regions. However, until very recently the nature of the etiologic agent was unclear, and relatively few laboratories actively studied the disease.
Download or read book Inflammation and the Microcirculation written by D. Neil Granger and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microcirculation is highly responsive to, and a vital participant in, the inflammatory response. All segments of the microvasculature (arterioles, capillaries, and venules) exhibit characteristic phenotypic changes during inflammation that appear to be directed toward enhancing the delivery of inflammatory cells to the injured/infected tissue, isolating the region from healthy tissue and the systemic circulation, and setting the stage for tissue repair and regeneration. The best characterized responses of the microcirculation to inflammation include impaired vasomotor function, reduced capillary perfusion, adhesion of leukocytes and platelets, activation of the coagulation cascade, and enhanced thrombosis, increased vascular permeability, and an increase in the rate of proliferation of blood and lymphatic vessels. A variety of cells that normally circulate in blood (leukocytes, platelets) or reside within the vessel wall (endothelial cells, pericytes) or in the perivascular space (mast cells, macrophages) are activated in response to inflammation. The activation products and chemical mediators released from these cells act through different well-characterized signaling pathways to induce the phenotypic changes in microvessel function that accompany inflammation. Drugs that target a specific microvascular response to inflammation, such as leukocyte-endothelial cell adhesion or angiogenesis, have shown promise in both the preclinical and clinical studies of inflammatory disease. Future research efforts in this area will likely identify new avenues for therapeutic intervention in inflammation.

Download or read book Arrest chemokines written by Klaus Ley and published by Frontiers Media SA. This book was released on 2015-05-20 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Anthrax written by Theresa Koehler and published by Springer Science & Business Media. This book was released on 2002-07-24 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacillus anthracis causes anthrax in all mammals, including humans. Depending upon the route of entry of B. anthracis spores, infection can result in cutaneous lesions, which are readily treatable with antibiotics, or systemic lethal disease, which is nearly always fatal. The continuing worldwide incidence of anthrax in animal populations, the risk of human infection associated with animal outbreaks, and the threat of use of B. anthracis as a biological weapon warrant continued investigation of this organisms and its virulence mechanims. Furthermore, B. anthracis is an excellent model system for inverstigation of virulence gene expression by bacteria.
Download or read book Vascular Growth Factors and Angiogenesis written by Lena Claesson-Welsh and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, the cellular and molecular mechanisms governing the development and regulation of the vasculature are studied in tensely and the field is rapidly progressing. Recently, novel growth factors and growth factor receptors specifically acting on endothelial cells have been discovered. Through these factors, communication networks are established between endothelial cells, the basement membrane and the pericytes; this interplay is critical for the regulated development and maintenance of the vasculature. The awareness that deregulated angiogenesis con tributes to the progression of a number of diseases, such as cancer and inflammatory diseases, has clearly spurred the field to move forward. The focus of this book is on two important classes of endothelial cell specific growth factors, the vascular endothelial growth factor (VEGF) family, and the angiopoietins, and on their mechanisms of action. The reader will find up-to-date, fo cused reviews, which give the current picture, and indicate future directions. I would like to honor Dr. Judah Folkman for his important contributions to the establishment of the field and thank him for his support. Lena Claesson-Welsh List of Contents N.

Download or read book Redirection of Th1 and Th2 Responses written by Robert L. Coffman and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two major subsets of CD4+ helper T cells, designated Th1 and Th2, have quite different patterns of cytokine production and, as a consequence, have very different roles in immune responses. The articles in this volume review both basic and clinical studies of T cell heterogeneity, including: the mechanisms by which Th1 and Th2 cells develop and maintain their differences in cytokine production; the different roles of Th1 and Th2 cells in allergy, autoimmunity and infectious diseases; the prospects and strategies for therapeutic manipulation of Th1 and Th2 cells; and the control of Th1 and Th2 responses by regulatory T cell subsets. The volume should give the reader a view of the development and function of Th1 and Th2 cells and the attempts to treat immunological diseases with therapies directed towards altering the Th1/Th2 balance.

Download or read book Toll Like Receptor Family Members and Their Ligands written by Bruce Beutler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: On occasion, the innate immune system is referred to as the "primitive" immune system. Perhaps this has dissuaded immu nologists from analyzing it as energetically as they have analyzed the adaptive immune system during the past two decades. But while its phylogenetic origins are indeed ancient, and though it is "of the first type", there is nothing crude, nothing unsophisti cated, and nothing "inferior" about innate immunity. On the contrary, the innate immune system has had time to achieve a level of refinement that is nothing short of dazzling, and a modicum of respect is at long last due. Any immune system has two cardinal functions. It must destroy a broad range of pathogens, and it must spare the host. The adaptive immune system has applied a modular solution to these problems. Each cell of the adaptive immune system is prescreened to eliminate those that would produce untoward interactions with self; each cell is pre-programmed to recognize a foreign epitope that the host might one day encounter. Hence, the duties of each individual lymphocyte are quite circumscribed.
Download or read book Immunobiology of Bacterial CpG DNA written by H. Wagner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacterial CpG-DNA sequences not only serve for genetic information but act as "danger" signal to alert immune cells such as macrophages and dendritic cells. CpG-DNA directly causes activation of these members of the innate immune system yielding in up-regulation of co-stimulatory molecules and pro-inflammatory cytokines. As such they act as "natural" adjuvants to promote protective Th1 polarized T cell immune responses. This book is the first comprehensive review of the data emerging in this field.
Download or read book Japanese Encephalitis and West Nile Viruses written by John Mackenzie and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Japanese encephalitis and West Nile viruses are members of the Japanese encephalitis serological group of the genus Flavivirus and therefore closely related genetically and antigenically. They share a number of properties, including the use of birds as their major wildlife maintenance host and Culicine mosquitoes for transmission, and they are both associated with severe human disease, as well as fatal infections in horses. The emergence of these two viruses, and their well-established propensity to colonise new areas, make it timely to re-examine their ecology, biology, molecular structure, replication and epidemiology, and these therefore provide the focus of this volume.
