Possibility of Coagulation System Activation Determination with Tissue Factor in Pregnancy Complications

Popis výsledku v původním jazyce

Background: In this part of the study, where we determined the causes of preeclampsia and other obstetric complications, we focused on the role of tissue factor (TF) in the activation of these pathophysiological processes. Recent findings attribute a significant part of the activation of coagulation creation of autoantibodies. Once this mechanism is activated, the antibodies induce expression of tissue factor (TF, CD142) on monocytes and vascular endothelial cells. Methods: We have proposed a monitor activation model of the coagulation system in preeclampsia and other pregnancy complications using TF expression on monocytes by flow cytometry and simultaneous determination the TF-induced thrombin generation in plasma. To determine expression of tissue factor (CD142) on monocytes, we proposed a method of multicolor flow cytometry using anti CD45 PerCP, anti CD14 APC, anti CD16b FITC, and anti CD142 PE antibodies and the corresponding isotype controls. Results: We verified the model on patients with severe antiphospholipid syndrome, which is a high expression of antibodies, in particular against beta-2GPI. Conclusions: We demonstrated complete inhibition of TF expression on monocytes and a significant reduction of thrombin generation in plasma.
