To explore the role of ATP-binding cassette (ABC) transporters in maintaining fetal metabolic homeostasis and their dysfunction in various obstetric complications.
Approach:
Integration of Data: Combines recent cryo-electron microscopy structures, single-cell transcriptomic data, and ex vivo studies of placenta pharmacology.
Focus on Transporter Dysfunction: Examines the mechanisms of transporter dysfunction in conditions such as preeclampsia, gestational diabetes, and others.
Key Findings:
ABC transporters are crucial for nutrient transport and blocking harmful substances at the maternal-fetal interface.
Transporters like P-gp/ABCB1 and BCRP/ABCG2 prevent maternal compounds from entering fetal circulation.
Dysfunction of ABC transporters is linked to several obstetric complications, including preeclampsia and gestational diabetes.
Interpretation:
The regulation of ABC transporters is dynamic and can be disrupted in obstetric complications, impacting fetal health.
Limitations:
The molecular mechanisms of ABC transporter dysfunction in obstetric pathologies are not fully understood.
Existing reviews have not integrated recent structural advances and the full spectrum of complications across all ABC subfamilies.
Conclusion:
ABC transporters are essential for maintaining fetal metabolic homeostasis during gestation.
