Project description:Decidual macrophage populations, CD11cHI and CD11cLO cells were analyzed for expression profiles and unique characteristics. We used microarrays to detail the global program of gene expression and to determine differences between these two unique decidual macrophage populations. First trimester decidual tissue was digested in order to release immune cells. Cells were stained for CD14 and CD11c and purified by MoFlo sorting. Cells were immediately lysed for RNA extraction and hybridization on Affymetrix microarrays. We utilized 8 patient paired samples (total of 16 microarrays).

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:Uterine macrophages are thought to play an important regulatory role at the maternal-fetal interface. We report here a unique gene expression pattern intrinsic of first trimester decidual monocytes/macrophages, but not of their blood counterparts. The micro-array data comprises approximately 14,000 genes. Some of the key findings were confirmed by real time PCR or secreted protein measurements. A large number of regulated genes were found to be functionally related to immunomodulation and tissue remodelling, corroborating polarization patterns of differentiated macrophages of M2 phenotype. These include M2 markers such as CCL-18, CD209, insulin-like growth factor (IGF)-1, mannose receptor c type (MRC)-1 and fibronectin-1. Further, the selective up-regulation of triggering receptor expressed on myeloid cells (TREM)-2, alpha-2-macroglobulin (A2M) and prostaglandin D2 synthase (PGDS) provides new insights into the regulatory function of decidual macrophages in pregnancy. In addition, a large number of regulated genes in the micro-array analysis were related to cell cycle regulation. Taken together, molecular characterization of decidual macrophages presents a unique transcriptional profile replete with important components for fetal immunoprotection. Experiment Overall Design: Comparative expression analyis of CD14+ cells isolated either from blood or decidua. Decidual tissue and blood was obtained from eleven women between 18 and 41 years of age

Project description:Uterine (decidual) macrophages (M) are believed to play an important role in fetal tolerance during pregnancy, but the factors that regulate them are not known. In this study we investigated the potential role of several factors (M-CSF, GM-CSF, IL-4/13, IL-10, progesterone and estradiol) to drive the differentiation and polarization of human decidual M by using an in vitro M differentiation model. To estimate the similarity of the in vitro differentiated M with decidual M, we used the present gene expression array. The array consisted of 420 M-related genes, including 100 genes highly regulated in decidual M based on the gene expression profile previously reported (Gustafsson et al, 2008, PLoS ONE. 3(4): e2078). The analysis focused on the 100 decidual M-associated genes. Comparative expression analysis of CD14+ cells isolated from blood (3 samples) or decidua (3 samples) from pregnant women, CD14+ cells isolated from non-pregnant women (14 samples) and different types of in vitro-generated macrophages (55 samples). A total of 75 samples were anlayzed.

Project description:To understand the regulation of cytotoxicity by decidual CD8+ T cells (CD8+ dT) at the maternal-fetal interface, gene expression analysis of CCR7-CD45RA- effector-memory CD8+ T cells isolated from peripheral blood of unrelated healthy controls and decidual tissue from first trimester (6-12 weeks) and term (>37 weeks) pregnancy was performed. Furthermore, first trimester decidual effector-memory CD8+ T cells were stimulated with anti-CD3/CD28 in the presence of IL-2 for 12 hours or 72 hours. RNA was isolated and gene expression profiles were generated by employing Affymetrix HG_U133_Plus 2 arrays on the Affymetrix Geneatlas system.

Project description:A successful pregnancy requires many physiological adaptations from the mother, including the establishment of tolerance towards the semiallogeneic fetus. Innate lymphoid cells (ILCs) have arisen as important players in immune regulation and tissue homeostasis at mucosal and barrier surfaces. Dimensionality reduction and transcriptomic analysis revealed the presence of two novel CD56Bright decidual ILCs, C10 and C2, that express divergent levels of Eomes. We found that decidual C10, C2, and cNKs correlated highly with previously identified first trimester decidual dNKs (dNK1-3). Functional analysis revealed polyfunctional profiles that depend on the nature of the stimulus, with a preference for IFNgamma and VEGF production. Overall, our data suggests persistence of pregnancy-specific decidual innate lymphocytes across pregnancy.
