Preeclampsia is characterized by placental complement dysregulation.
Increasing evidence suggests that preeclampsia is associated with complement dysregulation. The origin of complement dysregulation in preeclampsia is unknown, and further unraveling this mechanism could provide both diagnostic tools and therapeutic targets. Because the placenta is believed to play a crucial role in the pathogenesis of preeclampsia, we investigated placentas from preeclamptic wo...
متن کاملPlacental Aromatase Is Deficient in Placental Ischemia and Preeclampsia
INTRODUCTION Preeclampsia is a maternal hypertensive disorder with uncertain etiology and a leading cause of maternal and fetal mortality worldwide, causing nearly 40% of premature births delivered before 35 weeks of gestation. The first stage of preeclampsia is characterized by reduction of utero-placental blood flow which is reflected in high blood pressure and proteinuria during the second h...
متن کاملPlacental isoprostane is significantly increased in preeclampsia.
We determined placental tissue levels, production rates, and secretion rates of isoprostanes for placentas obtained from women with normal pregnancies and women with preeclampsia, a hypertensive disorder of pregnancy. Isoprostanes are markers of oxidative stress that exert biological actions such as vasoconstriction. Placental tissue was rinsed and immediately frozen in liquid nitrogen to deter...
متن کاملPlacental cytokines and preeclampsia.
Preeclampsia is a serious and life-threatening pregnancy complication. Reduced uteroplacental perfusion and oxygen tension, impaired trophoblast differentiation and invasion, and altered placental production of immunomodulators and growth factors are all considered to be important aspects in the aetiology of the condition. The placenta expresses a variety of pro and anti-inflammatory cytokines,...
متن کاملPreeclampsia is Characterized by Fetal NK Cell Activation and a Reduction in Regulatory T Cells
PROBLEM Preeclampsia affects 3-17% of pregnancies worldwide and has serious consequences for both the mother and the fetus. As maternal-fetal immune tolerance is bidirectional, fetal immunopathology may play a significant role in the pathogenesis of pregnancy disorders. Nevertheless, the impact of preeclampsia on the fetal immune system is unclear. METHOD OF STUDY In this case-control study, ...
