Transcriptional and Functional Programming of Decidual Innate Lymphoid Cells

ABSTRACT: 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.

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.

Whole genome expression profile of human decidual PMN-MDSC and autologous neutrophils in normal pregnancy

Project description:It is suggested that decidual polymorphonuclear myeloid-derived suppressor cell (PMN-MDSCs) are a group of activated suppressive neutrophils. Decidual microenvironment can facilitate circulating neutrophils with phenotypes and functions of PMN-MDSCs. The mechanism of PMN-MDSCs differentiation induced by decidual microenvironment has not been fully understood. Here we performed whole genome expression profile of 3 decidual PMN-MDSCs and autologous neutrophils from normal early pregnancy. Total RNA were extracted. The arrays were scanned by the Agilent Scanner G2505C. There were differences of gene expression pattern between decidual PMN-MDSCs and autologous neutrophils in early normal pregnancy.

Bone marrow-derived progenitors become decidual cells and are essential for implantation and pregnancy maintenance

Project description:The pregnant decidua is infiltrated by many immune cells which are thought to originate in the bone marrow (BM) promoting pregnancy. In addition, BM-derived progenitor cells (BMDPCs) become non-hematopoietic endometrial cells. However, whether BMDPCs become non-immune decidual cells and their functional contribution to pregnancy were previously unknown. Here, we show that embryo implantation stimulates vast BMDPCs recruitment to decidua, where BMDPCs differentiate into non-hematopoietic stromal decidual cells. In addition, to determine the functional importance of BMDPCs to pregnancy, we used mice with endometrial stromal-specific defects precluding successful pregnancy. BM transplant (BMT) from wild-type (WT) into Hoxa11-/- mice, which lack decidualization, results in uterine transcriptional changes leading to stromal expansion, gland formation, and marked decidualization otherwise absent in Hoxa11-/- mice. By contrast, BMT from Hoxa11-/- into WT mice induces pregnancy loss. Importantly, in Hoxa11+/- mice, which have increased pregnancy losses, BMT from WT donors leads to normalized expression of numerous decidualization-related genes and rescue of pregnancy loss. Collectively, these findings reveal that BMDPCs have a novel non-hematopoietic physiologic contribution to decidual stroma, thereby playing indispensable roles in pregnancy establishment and maintenance.

Single-cell transcriptomic analysis of decidual immune cell landscape in the occurrence of adverse pregnancy outcomes induced by Toxoplasma gondii infection

Project description:Toxoplasma gondii (T. gondii) is an obligate intracellular parasite that can lead to adverse pregnancy outcomes, particularly in early pregnancy. Previous studies have illustrated the landscape of decidual immune cells. However, the landscape of decidual immune cells in the maternal–fetal microenvironment during T. gondii infection remains unknown. In this study, we employed single-cell RNA sequencing to analyze the changes in human decidual immune cells following T. gondii infection. Our results showed that the proportion of 17 decidual immune cell clusters and the expression levels of 21 genes were changed after T. gondii infection. Differential gene analysis demonstrated that T. gondii infection induced the differential expression of 279, 312, and 380 genes in decidual NK, dMφ, and dT cells, respectively. Our findings first revealed that several previously unknown molecules in decidual immune cells changed following T. gondii infection. This result revealed that the function of maternal–fetal immune tolerance declined, whereas the killing ability of decidual immune cells enhanced, eventually contributing to the occurrence of adverse pregnancy outcomes. The results of this study provide a valuable resource for uncovering several novel molecules that play an important role in the occurrence of abnormal pregnancy outcomes induced by T. gondii infection.

Fatty-acyl conjugated amino-hexyl agarose pulldown with HeLa SILAC whole cell extract

Project description:C10:0 and C14:0 fatty acids were conjugated onto agarose beads, and used for pull-down with stable isotope (light: K0R0, heavy: K8R10) labeled Hela whole cell extract. C2:0 conjugated beads were used as control. Both forward (C2:0-light, C10:0 or C14:0-heavy) and reverse (C2:0-heavy, C10:0 or C14:0-light) labeling and pull-down experiments were performed.
