Transcriptomic signature associated with education in uterine Natural Killer cells during pregnancy

Project description:Uterine natural killer (uNK) cells regulate vascular changes crucial for placental function and fetal growth. The functional capacity of uNK cells is shaped by their education status. To explore the mechanisms of uNK cell education, we isolated NKG2A+ and Ly49C/I+ educated uNK cells and compared their transcriptomes to uneducated NKG2A-Ly49C/I- uNK cells.

Human uterine Natural Killer cells regulate differentiation of extravillous trophoblast early in pregnancy - bulk RNA-seq data

Project description:An allorecognition system depending on interactions between uterine Natural Killer (uNK) cells and placental extravillous trophoblast (EVT) during early pregnancy influences reproductive outcomes in humans. Our previous immunogenetic studies show that particular combinations of maternal Killer Immunoglobulin-like Receptors (KIR) in uNK cells with fetal HLA-C variants on EVT are associated with disorders of pregnancy, especially pre-eclampsia. To identify responses stimulated in uNK cells specifically when activating KIR (KIR2DS1) binds to C2+HLA-C, a combination protective against pre-eclampsia, we modelled KIR-HLA interactions by co-culturing uNK cells with the 721.221 HLA-null cell line transfected to express either C1+ or C2+HLA-C molecules, followed by transcriptome profiling by RNA sequencing. We detect the secretion of key cytokines by uNK cells under the protective combination between KIR2DS1 and C2+HLA-C.

Genome-wide analysis of uterine natural killer cell gene expression from control diet-fed and high fat diet-fed female mice in early pregnancy

Project description:Analysis of gene expression in uterine natural killer cells purified from control, diet-induced obese and diet-induced obese resistant female mice. The aim of the study is to identify differentially expressed genes and pathways in uterine natural killer cells affected by maternal diet and obesity in pregnancy.

Human uterine Natural Killer cells regulate differentiation of extravillous trophoblast early in pregnancy - scRNA-seq data

Project description:We used trophoblast organoids differentiating to extravillous trophoblast (EVT) to study the effects of key cytokines secreted by uterine Natural Killer (uNK) cells on EVT behaviour. Specifically, we exposed the organoids to four uNK-derived cytokines (CSF1, CSF2, XCL1, CCL5) and collected cells at different time points along the EVT differentiation pathway for scRNA-seq. We observe enhanced EVT differentiation in cytokine-treated organoids demonstrated by the increased proportion of late EVT subtypes and regulation of related pathways such as epithelial-mesenchymal transition. Moreover, uNK cytokines affect other processes important during early pregnancy including dampening of inflammatory and adaptive immune responses, regulation of blood flow, and placental access to nutrients.

Genome-wide analysis of uterine natural killer cell gene expression from lean and obese women in early pregnancy

Project description:Analysis of gene expression in uterine natural killer (NK) cells purified from either lean (control) or obese pregnanct women. The studys' aim is to identify differentially expressed genes and pathways in natural killer cells that are affected by maternal obesity. Results provide mechanitic insight into gene pathways altered in the condition of obeisty. Total RNA obtained from immuno-magnetic bead purified natural killer cells from uterine decidual mucosa from 7 to 10 week old pregnancies from 13 lean (BMI 20-24.9) and 11 obese (BMI >30) women. All women were between 19 and 35 years of age. In addition to BMI, blood serum CRP (hsCRP), a measure of inflammation, was measured via ELISA.

Regulatory T cells promote decidual vascular remodeling by modulating uterine natural killer cells to support pregnancy in mice

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.

Bulk RNA-seq and ATAC-seq of mouse uterine tissue-resident natural killer cells.

Project description:Uterine natural killer(NK) cells play a crucial role in pregnancy by promoting spiral artery remodeling and secreting fetal growth factors.Uterine trNK cells before pregnancy and during pregnancy (gd6.5, gd8.5 and gd11.5) were sorted, then applied into bulk RNA-sequence to reveal the features at different timepoints. Similarily, uterine trNK cells with different treatment in vitro were also sorted for bulk RNA-sequence to identify the role of IL-21-STAT3 signaling. To interpret the differentiation trajectory of uterine trNK cells, CD45+NKp46+NK1.1+ cells in wild-type virgin mice, wild-type gd8.5 mice, Il21r-/- gd8.5 mice and Il21r-/- gd8.5 mice with Caspase3 inhibitor are sorted.Applying them to Single-Cell RNA sequence, a differentiation trait of uterine NK cells during pregancy was revealed and IL-21 significantly promoted this process at initial stage.
