Gestational diabetes mellitus (GDM) is one of the most common endocrine disorders during gestation and affects around 15% of all pregnancies worldwide, paralleling the global increase in obesity and type 2 diabetes. Normal pregnancies are critically dependent on the development of maternal insulin resistance balanced by an increased capacity to secrete insulin, which allows for the allocation of nutrients...
Placental syncytiotrophoblast (STB) release extracellular vesicles (STB-EVs) that communicate physiological and pathological placental signals to the maternal organs. STB-EV release also increases in preeclampsia (PE). Here we explored the cargo of PP13 in STB-EVs from PE versus control placentas.Placentae were harvested following cesarean section deliveries, and dual placental lobe perfusion was...
The maternal physiology experiences numerous changes during pregnancy which are essential in controlling and maintaining maternal metabolic adaptations and fetal development. The human placenta is an organ that serves as the primary interface between the maternal and fetal circulation, thereby supplying the fetus with nutrients, blood and oxygen through the umbilical cord. During gestation, the placenta...
Exosome trafficking from the placenta into the maternal circulation is well documented; the possibility that this trafficking is bi‐directional was unknown. We demonstrated clathrin‐mediated endocytosis of macrophage exosomes by the human placenta. We also demonstrated that macrophage exosomes induced placental production of cytokines interleukin (IL)‐6, IL‐8 and IL‐10. Exosomes therefore comprise...
