    Polystyrene Nanoplastics Activate Autophagy and Suppress Trophoblast Cell Migration/Invasion and Migrasome Formation to Induce Miscarriage

    The authors selected polystyrene nanoplastics (PS-NPs) as a model of plastic particles and treated human trophoblast cells and pregnant mice with PS-NPs at doses near the actual environmental exposure doses of plastic particles in humans.

    The Anti-COVID-19 Drug Paxlovid Crosses Biological Barriers of the Placenta and Brain in Rats

    Scientists investigated whether nirmatrelvir crossed the blood-placenta barrier to reach the conceptus during pregnancy and the blood–brain barrier in male rats.

    ISRIB Facilitates the Co-Culture of Human Trophoblast Stem Cells and Embryonic Stem Cells

    By screening 1639 chemicals, researchers found that an inhibitor of integrated stress response, ISRIB, could replace WNT agonists and TGFβ inhibitors to maintain the stemness and differentiation capacity of human trophoblast stem cells.

    Huc-MSC-Derived Exosomal miR-144 Alleviates Inflammation in LPS-Induced Preeclampsia-Like Pregnant Rats via the FosB/Flt-1 Pathway

    Investigators explored the effects of human umbilical cord-derived exosome MSCs on preeclampsia (PE)-like models. Lipopolysaccharide was used to construct in vitro and in vivo PE-like models.

    Bitter Taste Receptors in the Reproductive System: Function and Therapeutic Implications

    In the uterus, TAS2Rs contribute to uterine relaxation and hold potential as therapeutic targets for preventing preterm birth. In the placenta, they are proposed to function as vigilant sentinels, responding to infection and potentially modulating mechanisms of fetal protection.
