Preeclampsia (PE) is a pregnancy disorder where placental exosomes, carrying non-coding RNAs, contribute to disease development. Exosomes show promise as non-invasive biomarkers and therapeutic tools for managing PE.
Area of Science:
- Obstetrics and Gynecology
- Molecular Biology
- Biochemistry
Background:
- Preeclampsia (PE) is a significant cause of maternal and fetal morbidity, affecting 4-6% of pregnancies worldwide.
- The exact causes of PE are unknown, but extracellular vesicles, especially exosomes, are increasingly implicated in its development.
- Exosomes are nanoscale vesicles involved in intercellular communication, transporting molecules like non-coding RNAs (ncRNAs).
Purpose of the Study:
- To review current knowledge on exosome biogenesis in preeclampsia.
- To explore the diagnostic potential of exosomal ncRNAs as non-invasive biomarkers for PE.
- To discuss emerging therapeutic strategies utilizing exosomes for PE management.
Main Methods:
- Literature review synthesizing current research on exosomes in preeclampsia.
- Analysis of exosome biogenesis pathways and their role in PE pathogenesis.
- Evaluation of diagnostic and therapeutic applications of exosomes and exosomal ncRNAs.
Main Results:
- Placental exosomes in PE exhibit altered molecular profiles.
- These altered exosomes contribute to endothelial dysfunction, immune dysregulation, and impaired angiogenesis in PE.
- Exosomal ncRNAs demonstrate potential as non-invasive biomarkers for PE diagnosis.
Conclusions:
- Exosomes play a crucial role in the pathogenesis of preeclampsia.
- Exosomal ncRNAs offer a promising avenue for non-invasive PE diagnostics.
- Engineered exosomes represent a potential precision medicine approach for PE treatment.
