Umbilical-brain endothelial communication via TSP-1 is linked with reduced brain angiogenesis in offspring of preeclampsia

Estefanny Escudero-Guevara, Felipe Troncoso, Hermes Sandoval…·Carlos Escudero

This study shows that TSP-1 from preeclampsia affects brain endothelial function by reducing angiogenesis and altering signaling pathways.

Circulating Microplastics as Acute Triggers of Platelet Activation and Coagulation: Implications for Cardiovascular Risk

Andrés Trostchansky, Marcelo A. Alarcón

This study shows that nanoplastics bind to and activate human platelets, promoting coagulation and thrombus formation, suggesting a new environmental risk factor for cardiovascular disease.

Bioinformatic analysis of placental exomiRs targeting the brain in preeclampsia

Marcelo A. Alarcón, Claudio R. Aguayo, Manu Vatish, Carlos Escudero

This study identifies differentially expressed placental exomiRs in preeclampsia and links them to maternal brain dysregulation through bioinformatic analysis and proteomic integration.
