Role of exosomal microRNA signatures: An emerging factor in preeclampsia-mediated cardiovascular disease

Area of Science:

• Obstetrics and Gynecology
• Cardiovascular Research
• Molecular Biology

Background:

• Preeclampsia (PE) and associated vascular dysfunction are significant contributors to maternal and neonatal mortality.
• The precise pathophysiology of PE remains incompletely understood despite extensive research.
• Exosomes, containing microRNAs (miRNAs), are increasingly recognized as critical mediators in PE-related cardiovascular diseases (CVDs).

Purpose of the Study:

• To review and discuss the current evidence on the function of exosomal miRNAs (exomiRs) in preeclampsia.
• To highlight the potential role of exomiRs in the cardiovascular dysfunction associated with PE.
• To identify gaps in knowledge and suggest future research directions for exomiR signatures in PE.

Main Methods:

• Literature review of existing studies on exosomes, miRNAs, and preeclampsia.
• Analysis of current understanding of exomiR biogenesis and function.
• Synthesis of evidence linking exomiRs to cardiovascular pathology in PE.

Main Results:

• Exosomes contain functionally active miRNAs that can influence physiological and pathological processes.
• While the role of miRNAs in PE is studied, the specific impact of exosomal miRNAs (exomiRs) is less understood.
• Existing evidence suggests exomiRs play a significant role in mediating CVDs associated with PE.

Conclusions:

• Exosomal miRNAs represent a crucial, yet understudied, component in the pathophysiology of preeclampsia.
• Further investigation into exomiR signatures is essential for understanding and potentially treating cardiovascular dysfunction in PE.
• Future research should focus on elucidating the specific mechanisms by which exomiRs contribute to PE-related vascular complications.
