This book was released on 2003 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrins are the major family of cell adhesion receptors for extracellular matrix (ECM) components and are involved in cell-cell and cell-ECM adhesion. Integrins also participate in cytoskeletal rearrangements, activation of signal transductions, and co-regulation of growth factor activities. In this dissertation, I have investigated the role of [beta]1 integrin-mediated adhesion and signaling during early Xenopus retinal development. First, I characterized the expression patterns of focal adhesion associated proteins, [beta]1 integrin, talin, vinculin, paxillin and phosphotyrosine in retinal glial cell line XR1 and in the developing Xenopus retina. These proteins are colocalized at focal adhesions located at the termini of F-actin filaments in XR1 cells. These proteins display spatial and temporal expression patterns, which are related with specific morphologies during retinal development. The similar and differential expression patterns suggest that focal adhesion proteins are involved in integrin-mediated adhesion and signaling, and are likely to be essential in regulating retinal morphogenesis. Second, I tested the hypothesis that protein tyrosine kinase (PTK) activity is essential for Xenopus retinal development. Inhibition of tyrosine kinase activity blocked focal adhesion assembly in cultures of dissociated retinal neuroepithelial cells and XR1 glial cells. Application of PTK inhibitors to embryonic retina disrupted retinal lamination and photoreceptor morphogenesis. The expression patterns of phosphotyrosine and [beta]1 integrins were also disrupted. Finally, I directly blocked integrin-ECM interactions with a disintegrin echistatin and observed the effects of the blockage on the retinal development. Echistatin inhibited XR1 glial cell attachment to fibronectin substrates, and also blocked cell spreading and focal adhesion assembly in XR1 cells. In addition, echistatin reduced the tyrosine phosphorylation levels of paxillin. Furthermore, application of echistatin to embryonic retina disrupted the retinal lamination and induced rosette structures with ectopic photoreceptors in the outer retina. Taken together, these results provide evidence that integrins are likely to play an important role in selective cell-ECM interactions, cell migration, differentiation and neurite outgrowth during retinal development. Focal adhesion associated proteins and tyrosine kinase activities are involved in the modulation of integrin-mediated adhesion and signal transduction pathways. This research contributes to our understanding of the functions and mechanisms of integrin-mediated adhesion during neural development.

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 Brain Development and Epilepsy written by Philip A. Schwartzkroin and published by . This book was released on 1995 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, developmental neurobiologists have made significant progress toward understanding the processes that determine normal organization and function of the central nervous system. Although this research provides the necessary basis for examining the factors that contribute to the age-dependent expression of seizures, there has been surprisingly little communication between developmental neurobiologists and the clinicians who deal with pediatric epilepsy patients. An understanding of normal and pathological functions in the immature central nervous system requires a special appreciation of developmentally unique mechanisms. This integrated volume applies the emerging concepts in developmental neurobiology to an understanding of the origins of the epilepsies of childhood. Early chapters give a picture of the age-specific epileptic syndromes and their associated pathologies, and describe experimental approaches toward understanding the basic mechanisms underlying these clinical phenomena. The following chapters provide an outline of developmental properties that may be critical to the generation of abnormal excitability, and pose hypotheses about pathological consequences of "mistakes" in key developmental processes. The final chapters attempt to integrate our knowledge of both maturational and epileptogenic mechanisms as a means not only for understanding epilepsies of the immature organism, but also for developing more effective treatment of these often devastating syndromes.
