Deep dives

Innovative Treatment for Preeclampsia

Researchers have developed a groundbreaking approach to treating preeclampsia by delivering mRNA to the placenta using lipid nanoparticles. Preeclampsia, a serious pregnancy complication, has limited therapeutic options that primarily manage symptoms rather than targeting the underlying causes. The innovative mRNA technique aims to induce the production of vascular endothelial growth factor (VEGF), which may help improve blood flow in the placenta. Early mouse studies demonstrated that this method significantly reduced hypertension and normalized fetal development, showcasing its potential as a curative treatment.
