Vascular contraction and preeclampsia: downregulation of the Angiotensin receptor 1 by hemopexin in vitro.
During normal pregnancy, in contrast to preeclampsia, plasma hemopexin activity is increased together with a decreased vascular angiotensin II receptor (AT(1)) expression. We now tested the hypothesis that hemopexin can downregulate the AT(1) receptor in vitro. Analysis of human monocytes or endothelial cells by flow cytometry showed decreased membrane density of AT(1) exclusively after incubat...
متن کاملVascular function in preeclampsia.
Preeclampsia is a multisystem disorder peculiar to human pregnancy. It occurs in 4-5% of all pregnancies and remains a leading cause of maternal and neonatal mortality and morbidity. The pathophysiology of this syndrome is not fully understood. Two stages of vascular dysfunction seem to be involved. In the early stage suboptimal development of the placenta and a hemodynamic maladaptation to pre...
متن کاملMaternal Vascular Physiology in Preeclampsia.
Preeclampsia is a systemic syndrome that occurs during pregnancy and postpartum and affects 3% to 8% of pregnancies. It is one of the leading causes of maternal and neonatal mortality and morbidity worldwide. The American College of Obstetricians and Gynecologists and the International Society for the Study of Hypertension in Pregnancy have set the following criteria for the clinical diagnosis ...
متن کاملPreeclampsia: long-term consequences for vascular health
Preeclampsia (PE) is a pregnancy-specific syndrome and one of the leading causes of preterm birth, neonatal and maternal morbidity and mortality. This disease is characterized by new onset hypertension usually in the third trimester of pregnancy and is sometimes associated with proteinuria, although proteinuria is not a requirement for the diagnosis of PE. In developing countries, women have a ...
متن کاملOxygen and vascular smooth muscle contraction.
DETAR, REED, AND DAVID F. BOHR. Oxygen and vascular smooth muscle contraction. Am. J. Physiol. 214(Z): 241-244. 1968.-Oxygen tension is an important determinant of the contractile tension developed by isolated helical strips of rabbit aorta. A decrease in PO:! below 100 mm Hg causes the contractile response to epinephrine (l-3 pg/liter) to diminish linearly to near zero levels at < 1 mm Hg. If ...
