Excessive hypercholesterolaemia during pregnancy as a risk factor for endothelial dysfunction in pre‐eclampsia

open access: yesThe Journal of Physiology, EarlyView.
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.

Differential effect of lead and cadmium on mitochondrial function and NLRP3 inflammasome activation in human trophoblast

open access: yesThe Journal of Physiology, EarlyView.
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 ...

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

open access: yesThe Journal of Physiology, EarlyView.
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).

Endothelial‐to‐mesenchymal transition in the fetoplacental macrovasculature and microvasculature in pregnancies complicated by gestational diabetes

open access: yesThe Journal of Physiology, EarlyView.
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.

High‐elevation adaptation and gestational hypoxia jointly shape vascular development in a rodent placenta

open access: yesThe Journal of Physiology, EarlyView.
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]

open access: yesFASEB J
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

open access: yesThe Journal of Physiology, EarlyView.
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

MCT1‐mediated bidirectional propionate transport across human placental syncytiotrophoblast layer: insights from a trophoblast stem cell‐derived barrier model

open access: yesThe Journal of Physiology, EarlyView.
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

open access: yesThe Journal of Physiology, EarlyView.
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.

A primary cell‐based fluidic co‐culture model to investigate drug transport across the human placenta

open access: yesThe Journal of Physiology, EarlyView.
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 ...
