The June/July NATO Advanced Study Institute resulted in these 15 papers that explore the cellular biology of vascular endothelium. Specific topics include an immunotherapeutic approach for the treatment of low plasma HDL-Cholesterol, effect of hyperlipemia and hyperglycemia on the vascular endothelium, endothelium-based approaches to stroke therapy, expressional regulation and subcellular localization of the nitric oxide receptor soluble guanylyl cyclase, and pathophysiological consequences of complement-endothelial cell interaction.
