Preeclampsia (PE) and vascular dysfunction are major causes of maternal and neonatal morbidity and mortality. Although extensively studied, the complete understanding of the pathophysiology behind PE remains unclear. Current reports indicate that exosomes are essential mediators in PE-related cardiovascular disease (CVDs). Exosomes are synthesized from multivesicular bodies (MVB) and contain functionally active microRNAs miRNAs). These miRNAs have been shown to mediate physiological and pathological functions through autocrine, paracrine, and endocrine signaling mechanisms. The role of miRNAs in pregnant women with PE has been studied extensively. However, little is known about the effect of exosomal miRNAs (exomiR) in PE. This paper will review and discuss the existing evidence for exomiR function in PE and highlight the need for future studies to explore the role that exomiR signatures have in cardiovascular dysfunction associated with PE.
