The Role of Extracellular Vesicles of Various Origins in the Development of Preeclampsia

Abstract

Pre-eclampsia is a clinically unfavorable pregnancy outcome that determines the main indicators of maternal and/or perinatal morbidity and mortality. According to modern concepts, the placenta plays a central role in the development of PE, while intercellular and intervesicular communications involving extracellular vesicles (EVs, extracellular vesicles) initiate a cascade of various biological effects, determining the mechanisms of ontogenesis of the gestational process in normal and pathological conditions. Achievements in studies of extracellular vesicles (EVs, extracellular vesicles) are of particular interest both to clinicians and to researchers studying the pathophysiology of gestational complications. Extracellular vesicles (EVs) in preeclampsia are produced both by scintiotrophoblast and the maternal body - blood cells (platelets, red blood cells, white blood cells) and the cardiovascular (vascular endothelium, smooth muscle) system. Changes in the concentration of these EVs can contribute to the implementation of preeclampsia, enhancing the pro-inflammatory and procoagulant states inherent in the gestation process. This review focuses on freely available information on the possible interactions between placental and maternal EVs. Understanding the contribution of EVs to the development of preeclampsia can help to deepen knowledge about the pathogenesis of this pathology and determine the diagnostic and prognostic significance of extracellular vesicles as biomarkers.
