چکیده

Preeclampsia is a multisystem complication in the second half of the pregnancy and characterized by hypertension and proteinuria. Although its specific pathophysiology is largely unknown, poor placentation, generalized inflammation and endothelial cell dysfunction are playing important roles. Recently, increased plasma levels of extracellular ATP have been found in women with preeclampsia. This increased ATP is considered to contribute to the development of the disease, since extracellular ATP has been shown to be a danger signal in many diseases. Extracellular ATP may increase blood pressure and activate endothelial cells and immune cells. In the circulation, ATP can be dephosphorylated to adenosine, which counteracts the effects of ATP. In the present review, we describe the importance of the delicate balance between extracellular ATP and adenosine in pregnancy and preeclampsia.

Plasma hemopexin as a potential regulator of vascular responsiveness to angiotensin II.

This brief review focuses on the functional activities of plasma hemopexin recently recognized by several authors. In particular, the protease-like activity of hemopexin in vitro is linked with downregulation of the vascular angiotensin II receptor in vivo, leading to vascular expansion. Also a potential mechanism of inhibition of hemopexin activity by extracellular adenosine triphosphate is co...

Plasma hemopexin activity in pregnancy and preeclampsia.

OBJECTIVE Plasma hemopexin activity, associated with increased vascular permeability, was evaluated in healthy pregnant and non-pregnant women and in pre-eclamptic women. METHODS Hemopexin activity and the hemopexin inhibitor, extracellular ATP, were assayed in plasma from pregnant (n = 10), preeclamptic (n = 9), and non-pregnant women (n = 10) using standard methods. Abdominal fascia tissue ...

Extracellular adenosine triphosphate affects systemic and kidney immune cell populations in pregnant rats.

PROBLEM Changes in the systemic immune response are found in preeclampsia. This may be related to high extracellular adenosine triphosphate (ATP) levels. The question arose whether ATP could affect immune responses in pregnancy. Previously, we investigated whether ATP affected monocyte activation and subpopulations. Here, we investigated ATP-induced changes in other immune cell populations in p...

Extracellular exosomes and preeclampsia: a microarray-based study and functional enrichment analysis

Background:  Preeclampsia (PE) is a heterogeneous pregnancy disease which the exact pathophysiology of it is unknown. Recently exosomes have been indicated as a causative factor in the pathogenesis of PE. The aim of the study was to investigate in microarray library data to extract the differentially expressed genes (DEGs) in PE and to perform a functional enrichment analysis to predict the rol...
