How early studies of inflammation led to our current views on the roles of vascular adhesion molecules.- Adhesion of leukocytes from flow: The selectins and their ligands.- Co-operative signaling between leukocytes and endothelium mediating firm attachment.- Production and presentation of chemokines by endothelial cells.- Platelet-activating factor: A signaling molecule for leukocyte adhesion.- Tight junctions and adherens junctions in endothelial cells: Structure and regulation.- The role of PECAM in leukocyte emigration.- Selective lymphocyte migration into secondary lymphoid rrgans and inflamed tissues.- Oxidation-reduction sensitive regulation of vascular inflammatory gene expression.- Quantification and imaging of vascular adhesion molecule expression in inflammatory diseases in vivo.- Leukocyte adhesion and activation in xenografts.- Control of leukocyte adhesion and activation in ischemia-reperfusion injury.- Control of leukocyte adhesion and activation in atherogenesis.
