Regulation of prostanoid-synthesis in the cardiovascular system.
Thromboxane A2 and prostacyclin are the two prostanoids involved in the regulation of the vascular tone. Their release is controlled by the activity of cyclooxygenase which has made this enzyme a preferred pharmacological target. We here report on the distribution of the two isoforms of cyclooxygenase in cultured mesangial cells and on a selective inhibitor of the cytokine-inducible cyclooxygenase-2. We also comment on the structure of thromboxane and prostacyclin synthase and their regulation under physiological and pathophysiological conditions.
