NSUN2‐Mediated m5C Modification of TGFB1 in Trophoblasts Remodels Macrophage Function to Prevent URSA

Advanced Science, EarlyView.
NSUN2 and m5C decline in URSA villous tissues. Trophoblast Nsun2 ablation disrupts macrophage‐mediated maternal‐fetal tolerance and triggers embryo resorption. Mechanistically, NSUN2‐YBX1 axis stabilizes m5C‐modified TGFB1 mRNA to maintain TGF‐β1 secretion and M2 polarization, and restoring this signaling rescues maternal‐fetal immune tolerance to ...

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

Topics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not

Plac1 Expression Pattern at the Mouse Fetomaternal Interface and Involvement in Trophoblast Differentiation

Cellular Physiology and Biochemistry, 2017
Background/Aims: It is well known that Plac1 is a placenta-specific gene; however, its spatiotemporal expression pattern and exact role at t h e mouse fetomaternal interface r e m a i n s unclear. Methods: In situ hybridization (ISH) was used to localize

CHD8‐Dependent Chromatin Licensing Sustains Trophoblast Stem Cell Transcriptional Programs

Advanced Science, EarlyView.
In this study, Huang et al., identify chromatin remodeler CHD8 as an essential factor in TSC maintenance and placental development. CHD8‐dependent chromatin accessibility supports the occupancy of key trophoblast TFs and is coupled to KMT2A‐associated H3K4me3 deposition at TSC stem and cell cycle genes, providing a permissive chromatin environment for ...

Up-and-down immunity of pregnancy in humans [version 1; referees: 2 approved]

F1000Research, 2017
One part of the human placenta in early pregnancy is particularly important for local immunity: the decidua basalis, which is transformed endometrium located at the site of embryo implantation.

TROP2‐Targeting Chimeras (TRTACs) for Tumor Cell‐Selective Membrane Protein Degradation and Enhanced Drug Delivery

Advanced Science, EarlyView.
TROP2 is identified as a novel tumor‐selective lysosomal‐targeting receptor with established clinical relevance. TROP2‐targeting chimeras (TRTACs) are developed by genetically fusing a TROP2‐binding nanobody to nanobodies against specific target proteins.

NK Cells and Trophoblasts [PDF]

The Journal of Experimental Medicine, 2004
In placental mammals, viviparity—the production of living young within the mother's body—evolved under the auspices of the immune system. Elements of immunity were incorporated, giving pregnancy a mildly inflammatory character. Formation of the placenta, the organ that feeds the fetus, involves a cooperation between maternal natural killer (NK) cells ...

Transcriptomic Profiling of SLC and ABC Transporters in the Human Term Placenta

Clinical Pharmacology &Therapeutics, EarlyView.
Solute carriers (SLC) and ATP‐binding cassette (ABC) transporters are essential for placental solute exchange and fetal protection, yet their transcriptomic profiles in the human placenta remain poorly characterized. Although fetal sex influences placental development and function, its impact on transporter expression is unclear.

Decidual macrophage‐mediated ferroptosis in trophoblasts leads to recurrent spontaneous abortion

iMeta
Recurrent spontaneous abortion (RSA) poses a significant challenge to successful early pregnancy, and trophoblast cell ferroptosis is an important pathogenic mechanism of RSA.

Effects of Human Umbilical Cord Mesenchymal Stem Cells on Human Trophoblast Cell Functions In Vitro

Stem Cells International, 2016
Trophoblast cell dysfunction is involved in many disorders during pregnancy such as preeclampsia and intrauterine growth restriction. Few treatments exist, however, that target improving trophoblast cell function.
