Nanomaterial-Based Strategies to Modulate Placental Dysfunction in Preeclampsia

Area of Science:

• Obstetrics and Gynecology
• Nanomedicine
• Maternal-Fetal Medicine

Background:

• Preeclampsia (PE) is a pregnancy-specific disorder causing hypertension and multi-organ dysfunction, primarily due to placental abnormalities.
• Pathological features include impaired trophoblast invasion, defective spiral artery remodeling, angiogenic imbalance, oxidative stress, and inflammation.
• Current management is supportive, necessitating novel therapies targeting the placenta with minimal fetal risk.

Purpose of the Study:

• To review the pathological mechanisms of placental dysfunction in preeclampsia.
• To discuss the design principles for safe and effective pregnancy nanomaterials.
• To evaluate emerging nanomedicine strategies for preeclampsia treatment.

Main Methods:

• Review of current literature on preeclampsia pathophysiology and nanomedicine applications.
• Analysis of nanomaterial design principles for placental targeting and safety.
• Evaluation of preclinical models and therapeutic strategies using nanomedicine.

Main Results:

• Nanomaterials enable targeted delivery to the placenta, controlled drug release, and modulation of pathogenic pathways.
• Placenta-targeted nanomedicine can attenuate oxidative stress, suppress inflammation, and restore angiogenic balance.
• Emerging strategies show potential in regulating placental gene expression and improving the microenvironment.

Conclusions:

• Nanomedicine presents a promising avenue for developing mechanism-based therapies for preeclampsia.
• Targeting placental dysfunction with nanomedicine offers a strategy to improve maternal and fetal outcomes.
• Further research and addressing translational challenges are crucial for advancing precision nanomedicine for preeclampsia.
