Abstract figure legend Excessive hypercholesterolaemia during pregnancy impairs maternal endothelial function, which, in turn, drives the development of pre‐eclampsia and may also contribute to the increased risk of later‐life cardiovascular disease in women.

Abstract figure legend The human placenta not only detects the presence of Pb and Cd but also carries hypoxia and inflammatory risks, which are associated with pregnancy complications. To understand the impact of these factors on the placental trophoblast, we evaluated the effect of Pb and Cd on mitochondrial function and the NLRP3 inflammasome in ...

Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

Abstract figure legend Transforming growth factor (TGF)‐β2 and interleukin (IL)‐1β induced morphological and molecular changes consistent with endothelial‐to‐mesenchymal transition (EndMT) in HUVECs isolated from both pregnancies complicated by gestational diabetes (GDM) and non‐GDM pregnancies.

Abstract figure legend We investigated how environmental hypoxia and genetic adaptation to high altitudes jointly impact the development of the placental exchange surface in ways that might protect fetal growth potential. We used wild‐derived, lab‐born North American deer mice (Peromyscus maniculatus) from low‐elevation and high‐elevation environments (

Innate Immunity and Microbial Recognition in Reproduction: From Barrier Defense to Maternal-Fetal Tolerance. [PDF]
Graphical abstract illustrating the barrier defense–tolerance framework of reproductive innate immunity. Across the female and male reproductive tracts and the maternal–fetal interface, epithelial barriers, innate sensors, immune cells, and microbial signals are integrated to preserve reproductive homeostasis.

Human placental exposure to pollutant nanoparticles: uptake, translocation and functional impact
Abstract figure legend Prenatal exposure to pollutant nanoparticles has been increasingly investigated due to concerns about their potential effects on placental function and pregnancy outcomes. Maternal inhalation of pollutant nanoparticles can result in a pro‐inflammatory response; particles can also translocate across the alveolus epithelial barrier

Abstract figure legend Propionate in the fetal circulation is thought to originate from fermentation of dietary fibre by the maternal gut microbiota. However, the mechanism of transplacental transport has remained unclear. Here, we measured propionate permeability using a placental barrier model generated by differentiating human placental trophoblast ...

Physiological and anatomical determinants of placental drug transfer
Abstract figure legend Fetal exposure to pharmaceuticals and their subsequent clearance back to the maternal circulation are governed by placental transfer. Passive diffusion down a maternal‐to‐fetal concentration gradient is the primary route of fetal drug exposure, with specific compounds undergoing transporter‐mediated transfer.

Abstract figure legend Schematic overview of a flow‐driven in vitro model of the human placental barrier designed to study transport processes during pregnancy. The model recreates key features of the maternal–fetal interface, enabling the investigation of how nutrients and therapeutic compounds cross the placental barrier under physiologically ...
