Project description:We used full genome microarrays to profile the full lifetime of the mouse placenta from embryonic day 8.5 (e8.5), at the time of chorioallantoic fusion, until postnatal day 0 (P0). At each stage, the fetal placenta and maternal decidual tissues were dissected and profiled separately Experiment Overall Design: Mouse placentas were obtained from timed pregnant female mice at each timepoint, and fetal tissues were used to confirm embryo staging. Fetal placenta and maternal decidual tissues were dissected and pooled separately for each litter prior to RNA extraction and hybridization on Affymetrix microarrays.

For these samples, at each stage the fetal placenta and maternal decidual tissues were dissected and profiled separately (See series 1). For this experiment (Series 2), placental and decidual timecourse samples were normalized and modeled with two undissected (including placental and decidual tissue) e17 placentas to allow for scaling of values for comparison to the undissected placenta samples used in the publicly available mouse GeneAtlas dataset Keywords: time course

Project description:A Toxoplasma gondii infection during pregnancy can result in spontaneous abortion, preterm labor, or congenital fetal defects. The decidual immune system plays a critical role in regulating the immune micro-environment and in the induction of immune tolerance. To better understand the factors that mediate the decidual immune response associated with the T. gondii infection, a large-scale study employing TMT proteomics was conducted to characterize the differential decidual immune proteomes from infected and uninfected human decidual immune cells samples. The decidual immune cells from 105 human voluntary abortion tissues were purified, and of the 5510 unique proteins identified, 181 proteins were found to be differentially abundant (>1.2-fold cutoff, P＜0.05) in the T. gondii-infected decidual immune cells. 11 proteins of 181 differentially expressed proteins associated with trophoblast invasion, placental development, intrauterine fetal growth, and immune tolerance were verified using a quantitative real-time polymerase chain reaction and western blotting. This systematic research identified a broad range of immune factors in human decidual immune cells, shedding a new insight into the decidual immune molecular mechanism for abnormal pregnancy outcomes associated with T. gondii infection.

Project description:Thiele2013 - Placenta decidual cells
The model of placenta decidual cells metabolism is derived from the community-driven global reconstruction of human metabolism (version 2.02, MODEL1109130000
).
This model is described in the article:
A community-driven global reconstruction of human metabolism.

Abstract:
Multiple models of human metabolism have been reconstructed, but each represents only a subset of our knowledge. Here we describe Recon 2, a community-driven,
consensus 'metabolic reconstruction', which is the most comprehensive representation of human metabolism that is applicable to computational modeling. Compared
with its predecessors, the reconstruction has improved topological and functional features, including ~2x more reactions and ~1.7x more unique metabolites. Using
Recon 2 we predicted changes in metabolite biomarkers for 49 inborn errors of metabolism with 77% accuracy when compared to experimental data. Mapping metabolomic
data and drug information onto Recon 2 demonstrates its potential for integrating and analyzing diverse data types. Using protein expression data, we automatically
generated a compendium of 65 cell type-specific models, providing a basis for manual curation or investigation of cell-specific metabolic properties. Recon 2 will
facilitate many future biomedical studies and is freely available at http://humanmetabolism.org/.

Project description:Macrophages are abundant in uterine mucosa during the peri-implantation phase and early pregnancy. Decidual macrophages display dynamic changes alone with pregnancy progress: During the peri-implantation phase, macrophages displayed a pro-inflammatory phenotype which facilitates embryo implantation. While, In the late firster trimester and second trimester, decidual macrophages are anti-proinflammatory which are helpful to pregnancy maintenance. Alterations in the ratio of pro-inflammatory/anti-inflammatory decidual macrophages lead to abortion, preeclampsia, and preterm birth. Placenta-derived exosomes (pEXO) are critical in the immune cell modulation such as T cell apoptosis, NK activities, and T regulatory (Treg) differentiation. However, it is unknown whether placenta-derived exosomes contribute to decidual macrophage polarization during early pregnancy. Here we report that exosomes from the placenta explant stimulate M2 macrophage polarization via exosomal miRNA-30d-5p. Mechanistically, miRNA-30d-5p polarized macrophages to M2 phenotype by inhibiting HDAC9 expression. Furthermore, the conditioned medium of pEXO-treated macrophages promoted trophoblast migration and invasion. By contrast, conditioned medium impaired the ability of endothelial cell tube formation. However, pEXO-treated macrophages have no impact on T cell proliferation. Together, we demonstrated that pEXO promoted trophoblast migration and invasion, endothelial cell migration, and attenuation of endothelial cell tube formation by polarizing macrophage to decidua-like macrophage.

Project description:Receptors of the KIR family on maternal Natural Killer cells in the decidua are believed to bind to Ligands such as HLA-C on trophoblast cells invading into the decidua from the placenta during early pregnancy. The resulting responses regulate the extent of trophoblast invasion. Genetic studies have implicated two members of the KIR family in particular as playing an important role: KIR2DL1 and KIR2DS1. The aim of this experiment was to determine what responses are generated when decidual NK cells bearing either KIR2DL1 or KIR2DS1 engage their HLA-C ligand.

Project description:The placenta is a transient organ that is repsonsible for multiple processes during pregnancy. Here we aim to study the development of the placenta using mouse models at embryonic day (e) e7.5, e8.5 and e9.5 by integrating RNA-seq data at the three timepoints to identify important genes, inferring their interaction networks, and predict novel regulators of placental development.

Project description:Regulatory T (Treg) cells are essential for maternal immune tolerance of the fetus and placenta. In preeclampsia, aberrant Treg cell tolerance is implicated, but whether and how Treg cells affect the uterine vascular dysfunction thought to precede placental impairment and maternal vasculopathy is unclear. We utilized Foxp3 DTR mice to test the hypothesis that Treg cells are essential regulators of decidual spiral artery adaptation to pregnancy. Transient Treg cell depletion during early placental morphogenesis caused impaired remodeling of decidual spiral arteries and altered uterine artery function, resulting in late gestation fetal loss and fetal growth restriction. Treg cell depletion impaired acquisition of the activation receptor NKp46 on uterine natural killer (uNK cells) and was associated with reduced decidual synthesis of Treg cell-derived cytokines Il35, Il10 and Tgfb implicated in modulating uNK cell phenotype. When Treg cells were replaced, the adverse impact on uNK cell abundance and phenotype, decidual spiral artery remodeling, uterine artery function, and fetal loss was mitigated. These data implicate Treg cells as essential upstream drivers of uterine vascular adaptation to pregnancy through regulation of uNK cell recruitment and activation. The findings provide a mechanism linking impaired adaptive immune tolerance and altered spiral artery remodeling, two hallmark features of preeclampsia.
