Placental exosomes polarize human monocyte-derived macrophages to a decidual M2-like macrophage phenotype

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.

Different expression of miRNA between the exosomes secreted by monocyte and M2 macrophage

Project description:The macrophages in tomor microenvironment in were alike M2 macrophages which contribute to tumor progression and migration. Since macrophages can secret lots of exosomes and M2 macrophage can induce the imbalance of Treg/Th17 ratio in EOC tumor environment, we want to investage the different expression of miRNA between the exosomes secreted by monocyte and M2 macrophage. Thus to see if the microRNA in exosomes secreted from M2 macrophage paly a big role in the T cell imbalance.

Placental and decidual timecourse samples normalized and modeled with an undissected e17 sample

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). 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

Proteomic profiling of human decidual immune proteins during Toxoplasma gondii infection

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.

Effects of dPRP (PRL8a2) on gene expression of decidual-placental-embryonic tissue

Project description:DPRP (PRL8a2) is critically involved in adaptations of the placentation site to physiological stressors. DPRP (PRL8a2) restrains the expression of genes associated with ER stress. We used DNA microarrays to analyze the transcriptome of wild type and dPRP null mouse decidual-placental-embryonic tissues from gestation day 7.5.

miRNA sequencing from exosomes derived from M1-or M2-polarized bone-marrow derived macrophages (BMDMs).

Project description:We reported exosome-guided phenotype switches between M1- and M2-polarized BMDMs. M1- or M2-polarized BMDMs were successfully reprogrammed to M2- or M1-phenotype via the treatment of exosomes obtained from M2- or M1-polarized BMDMs. In this uploaded information, the exosomes from M1- and M2-polarized BMDMs were analyzed by high-throughput sequencing.

Next Generation Sequencing of human first trimester placental EVTs (pEVT), decidual interstitial EVTs (iEVT), and trophoblast organoid (TB-ORG)-derived extravillous trophoblasts (TB-ORG-EVTs).

Project description:Aim of the study was to verify signaling pathway-provoked EVT specification in human first trimester placental and decidual tissue. We further provide improvement for in-vitro differentiated TB-ORG-EVTs to more closely mimic in-situ placental EVT geno- and phenotypes.

Environmental Pollutant Induced Cellular Injury is Reflected in Exosomes from Placental Explants

Project description:Environmental exposure of placental explants did not change the quantity of exosomes or their characteristics. However, exosome cargo composition was changed by specific pollutant to reflect a biochemical signature suggestive of placental nuclear and cellular injury and inflammation.

Human Placental Exosomes in Gestational Diabetes Mellitus Carry a Specific Set of miRNAs Associated with Skeletal Muscle Insulin Sensitivity

Project description:The objective of this study was to investigate whether placental exosomes in gestational diabetes mellitus (GDM) carries a specific set of miRNAs associated with skeletal muscle insulin sensitivity. Exosomes were isolated from chorionic villi-conditioned media and plasma from normal and GDM pregnancies. A specific set of miRNAs was identified to be selectively enriched within exosomes when compared to their cells of origin indicating specific packaging of miRNAs into exosomes. In addition, miRNA expression varies in a consistent pattern in placenta, placental-derived exosomes, circulating exosomes and skeletal muscle in GDM.
