The endothelium, a monolayer of endothelial cells, constitutes the
inner cellular lining of the blood vessels (arteries, veins and
capillaries) and the lymphatic system, and therefore is in direct
contact with the blood/lymph and the circulating cells. The
endothelium is a major player in the control of blood fluidity,
platelet aggregation and vascular tone, a major actor in the
regulation of immunology, inflammation and angiogenesis, and an
important metabolizing and an endocrine organ. Endothelial cells
controls vascular tone, and thereby blood flow, by synthesizing and
releasing relaxing and contracting factors such as nitric oxide,
metabolites of arachidonic acid via the cyclooxygenases,
lipoxygenases and cytochrome P450 pathways, various peptides
(endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine,
purines, reactive oxygen species and so on. Additionally,
endothelial ectoenzymes are required steps in the generation of
vasoactive hormones such as angiotensin II. An endothelial
dysfunction linked to an imbalance in the synthesis and/or the
release of these various endothelial factors may explain the
initiation of cardiovascular pathologies (from hypertension to
atherosclerosis) or their development and perpetuation. Table of
