title: Soluble adhesion molecules in inflammatory and vascular diseases.
abstract: For many years the vascular endothelium was believed simply to provide a passive lining between circulating blood and extravascular tissue. It is now clear, however, that this monolayer of cells on the luminal surface of all blood vessels, provides a selective barrier that responds dynamically to various stimuli, and controls a complex series of cellular reactions and interactions. The current presentation describes the use of computer enhanced video recording to study interactions between endothelial cells and circulating blood cells, especially leucocytes. Subsequently, modern assays for soluble cell adhesion molecules and other cell receptors were assessed for potential use in routine clinical practice. The results demonstrated that adhesive mechanisms involving leucocytes and endothelial cells involve a range of interrelationships that cut across conventional views of haemostasis and leucocyte function. The findings also suggest that interplay between the vascular lumen and circulating blood cells might be vitally important in clinically demanding pathologies, such as life-threatening sepsis, ischaemic heart disease, atherosclerosis and cancer. The concepts provide challenging strategies for further investigation.
