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 ...

A review of xenobiotic membrane transporter expression within the human placenta: Lessons gained from primary tissue and in vitro methodologies

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A summary of the current knowledge around membrane transporter expression in the most widely used in vitro models of human trophoblasts, including primary placental tissue, cancer cell lines and trophoblast stem cells, as well as the techniques to attempt to mimic the human placenta in vivo.

Transfer of paracetamol across the placenta and fetal blood–brain barriers and its safety for use in pregnancy

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Paracetamol (acetaminophen) is commonly taken during pregnancy for pain and fever. To gain a more comprehensive understanding of paracetamol's effects during pregnancy, several elements need to be examined including the transfer of paracetamol across the placenta and into the developing brain, the short‐ and long‐term effects of ...

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Virus‐specific alterations in placental structure and transporter expression following maternal arbovirus infection

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Arboviruses induce virus‐specific alterations in placental structure and functional markers. Chikungunya virus (CHIKV) exposure was associated with reduced syncytiotrophoblast and syncytial knot areas, increased cytotrophoblast proliferation (Ki‐67) and thyroid transporter (MCT8) expression, reduced protective (P‐gp and BCRP ...

Placental compliance during fetal extracorporeal circulation

open access: yesJournal of Applied Physiology, 2001
The fetus requires large amounts of volume when weaning from cardiac bypass. This suggests that placental vasculature can act as a large capacitor in the fetal circulation.

Effects of L‐arginine on utero‐placental circulation in growth‐retarded fetuses

open access: yesActa Obstetricia Et Gynecologica Scandinavica, 1996
Background. To evaluate the effects of L-arginine (ARG) infusion, the nitric oxide as substrate, on the utero-placental circulation at third trimester. Methods. Three groups of nine pregnant women each were infused i.v. with 30 g ARG, for 30 minutes. One
