Gene expression profile of decidual macrophages and different in vitro M1 and M2 macrophage populations

ABSTRACT: 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.

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.

Genome-wide analysis of M1 and M2 polarized macrophages with CNI-1493 treatment

Project description:Analysis of the effects of CNI-1493 treatment on M1 and M2 polarized macrophages. The purpose of this microarray is to identify genes that may be differentially expressed in M1 or M2 macrophages after treatment with CNI-1493. CNI-1493 is a known inhibitor of M1 macrophages but details of its molecular mechanism are unknown. The effect of CNI-1493 on M2 macrophages has yet to be explored, but we hypothesize that CNI-1493 treatment will attenuate pro-tumor properties of M2 macrophages. We demonstrate with this array that known macrophage markers are unchanged after treatment with CNI-1493, indicating that CNI-1493 does not change the macrophage phenotype on a transcriptional level. Additionally, no candidate genes to suggest how CNI-1493 may attenuate the pro-tumor effects of M2 macrophages are readily identifiable. Total RNA extracted from M1 or M2 macrophages after polarization with GM-CSF (25ng/ml) or M-CSF (25ng/ml) for 7 days, followed by addition of IFN-γ (20ng/ml) and LPS (100ng/ml) or IL-4 (40ng/ml) for 18 hours, respectively, from CD14+ human PBMCs, and treated with CNI-1493 (200nM)

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.

Transcription profiling of human decidual macrophages

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

Mechanisms of Chorioamnionitis-associated Preterm Birth: Interleukin 1 β inhibits Progesterone Receptor Expression in Decidual Cells

Project description:In chorioamnionitis (CAM), a major cause of preterm birth (PTB), maternal-fetal inflammatory responses in the decidua and amnio-chorion cause the release of cytokines that elicit cervical ripening, fetal membrane rupture and myometrial activation. We posited that this inflammatory milieu can trigger PTB via inhibited progesterone receptor (PR) expression and increased decidual prostaglandin (PG) production. We found significantly lower decidual cell PR levels in CAM-complicated PTB using immunohistochemistry. Decidual cells (DCs) treated with IL-1β displayed decreased PR expression and significantly increased PGE2 and PGF2α production and COX2 expression. While addition of PGF2α to DC cultures was also found to suppress PR expression, the COX inhibitor, indomethacin, did not reverse IL-1β suppression of PR expression in DC cultures. Although IL-1β treatment activated NF-B, ERK1/2 and p38 MAPK signaling cascades in DCs, only inhibition of ERK1/2 MAPK signaling completely reversed IL-1β suppressed PR levels. These findings suggest that CAM-associated PTB is induced at least in part by IL-1β-mediated functional progesterone withdrawal.
