Influence of placental lipid transport dysfunction on maternal brain inflammation during pregnancy complications

Introduction: The conditions associated with pregnancy, such as preeclampsia, gestational diabetes, and disruptions of Placental lipid transport, are increasingly becoming known to be the cause of intrauterine growth restriction. Recent data indicate that compensatory efforts can initiate neuroinflammatory and systemic reactions in the mother, which can influence foetal development. Methods: This study aims to learn how maternal brain inflammation and neuroimmune activation during complicated pregnancies can be triggered by abnormal placental lipid carriage. Results: PBIC-SM and NLIP-IM models are employed to examine lipid-induced CNS inflammation and neuroimmune lipidomic changes, focusing on how altered placental lipid transport affects maternal lipid profiles, oxidative stress, and inflammation. Conclusion: Disrupted lipid balance alters microglial activity and increases IL-6 and TNF-α levels, showing that impaired placental transport can trigger neuroinflammation during pregnancy. In high-risk cases, early intervention and targeted therapies may help preserve maternal mental health by addressing placenta-brain immune dysregulation.
