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.

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.

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.

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.

Expression profiling of Natural killer B cells

Project description:Investigation of global gene expression levels between B cells, Natural killer cells and Natural killer B cells Gene expression profiling using sorted B cells, Natural killer cells and Natural killer B cells from WT mouse spleen. Total RNA extracted from WT cells were quantified by the NanoDrop ND-1000 and RNA integrity was assessed by standard denaturing agarose gel electrophoresis. The sample preparation and microarray hybridization were performed based on the NimbleGenâs standard protocols.

Tissue-Resident Natural Killer (NK) Cells Are Cell Lineages Distinct From Thymic and Conventional Splenic NK Cells (part 1)

Project description:Natural killer (NK) cells belong to the innate immune system where they can control virus infections and developing tumors by cytotoxicity and production of inflammatory cytokines. Most studies of mouse NK cells, however, have focused on conventional NK (cNK) cells found in the spleen. Recently, we described two populations of NK cells within the liver, tissue-resident NK (trNK) cells and those resembling splenic cNK cells. However, the lineage relationship of trNK to cNK cells was unclear because trNK cells display a phenotype associated with immature, developing cNK cells. Moreover, liver trNK cells could be related to thymic NK cells or alternatively, a lineage distinct from both cNK and thymic NK cells. Herein we used detailed transcriptomic, flow cytometric, and functional analysis of mice deficient in several transcription factors to determine that liver trNK cells form a distinct lineage from cNK and thymic NK cells, especially because they do not require NFIL3 (E4BP4), the previously described NK cellspecification factor. Analysis of other tissues indicate the presence of trNK cells in skin and uterus with different transcription factor requirements. Thus, there are at least four distinct lineages of NK cells: cNK, thymic, liver (and skin) trNK, and uterine trNK cells. Liver NK 1.1+CD49+, liver NK 1.1+CD49-, spleen NK 1.1+ CD49- populations of NK cells were sorted with FACS pooling cells from individual mice to end up with ~100k cells for each samples. mRNA was derived from lysates using Invitrogen oligo-dT beads
