Expression data of human decidual NK cells from gravid uteri and NK cells from cycling endometrium

ABSTRACT: Human NK cells from the decidua basalis of gravid uteri (dNK) and from cycling endometrium (eNK) of women undergoing hysterectomy were isolated and compared by gene expression profiling using Affymetrix microarrays with probes representing ~47,400 transcripts. Substantial differences indicate that these two types of NK cells represent distinct subsets. Freshly isolated NK cells were obtained by FACS sorting. 4 dNK and 5 eNK samples were obtained form independent donors. dNK cells were isolated from the decidua basalis of first trimester placentas and sorted as CD3-, CD16-, CD56+ cells. eNK cells were obtained from non-affected regions of cycling endometrium of donor women undergoing hysterectomy and were sorted as CD45+, CD56+, CD3- cells . The preliminary patient diagnoses included genital prolapse, fibroids, cervical dysplasia, or menorrhagia. All cycling endometrium samples were from the secretory phase of the cycle with exception of sample eNK_S6 that was from the proliferative phase.

Immune and HCT116 RNA mixtures

Project description:These experiments were designed as a benchmark tool for deconvolution methods. 5 immune cell populations were sorted from 3 healthy donors' peripheral bloods. Peripheral Blood Mononuclear Cells (PBCMs) and PolymorphoNuclear Cells (PMN) were separated using gradient centrifugation. T cells (DAPI-/CD3+/CD14-/CD19-/CD56-), monocytes (DAPI-/CD3-/CD14+/CD19-/CD56-), B cells (DAPI-/CD3-/CD14-/CD19+/CD56-) and NK cells (DAPI-/CD3-/CD14-/CD19-/CD56+) were FACS-sorted from PBMCs and neutrophils (DAPI-/CD66b+/CD19-/CD3-/CD56-/CD14-) were sorted from PMNs. RNA was extracted from the purified cell population, as well as from the HCT116 colon cancer cell line. RNAs from pure populations were then mixed in various proportions. RNA from HCT116 cells and FACS-sorted T cells (DAPI-/CD3+/CD14-/CD19-/CD56-), monocytes (DAPI-/CD3-/CD14+/CD19-/CD56-), B cells (DAPI-/CD3-/CD14-/CD19+/CD56-), NK cells (DAPI-/CD3-/CD14-/CD19-/CD56+), and neutrophils (DAPI-/CD66b+/CD19-/CD3-/CD56-/CD14-) were mixed in various proportions.

Decidual NK cells Xiong et al 2013

Project description:Receptors of the KIR family on maternal Natural Killer cells in the decidua are believed to bind to Ligands such as HLA-C on trophoblast cells invading into the decidua from the placenta during early pregnancy. The resulting responses regulate the extent of trophoblast invasion. Genetic studies have implicated two members of the KIR family in particular as playing an important role: KIR2DL1 and KIR2DS1. The aim of this experiment was to determine what responses are generated when decidual NK cells bearing either KIR2DL1 or KIR2DS1 engage their HLA-C ligand.

Differential expression of Wnt signalling molecules between pre- and post-menopausal endometrial epithelial cells suggests that a population of putative epithelial stem/progenitor cells reside in the basalis layer

Project description:The human endometrium is a highly regenerative tissue that undergoes cyclical proliferation, differentiation and shedding each month. The upper functionalis layer of the endometrium is shed in response to circulating levels of estrogen and progesterone, while the lower basalis layer remains. Clonogenic epithelial stem/progenitor cells likely responsible for regenerating endometrial epithelium have been identified in pre-menopausal (Pre-M) and post-menopausal (Post-M) endometrium and may reside in the basalis layer. We undertook a transcriptional profiling of purified epithelial cells from full-thickness Pre-M and Post-M endometrium to identify differentially expressed genes. The hypothesis tested in the present study was that Post-M endometrial epithelial gene profile would be similar to the quiescent basalis epithelium of Pre-M endometrium. We found striking differential gene expression of many Wnt family members between Pre-M and Post-M and other stem cell network genes. Comparative analysis of our endometrial epithelial gene expression profiles to that of endometrial epithelial cells in remodelling endometrium also provides new evidence showing that Post-M endometrial epithelium has a similar gene signature to that of basalis epithelium of menstrual endometrium. Human endometrial tissue was obtained from 8 pre-menopausal and 3 post-menopausal women undergoing hysterectomy for various benign gynaecologic conditions. Endometrial tissue was digested and isolated using combination of DNase and collagenase. Anti-human EpCAM antibody-coated magnetic Dynabeads was used to positively select total epithelial cells from the digested single cell suspensions. Total RNA was extracted from the purified endometrial epithelial cells and hybridised to Illumina Sentrix HT12 beadchip. Resulting data was compared between pre-menopausal and post-menopausal samples.

Epigenetic characterization of NKG2C high cells of primigravid decidual NK, multigravid decidual NK, nulligravid endometrial NK and multigravid endometrial NK

Project description:Natural killer cells (NKs) are abundant in the human decidua. Several diseases of poor placental development are associated with first pregnancies, and we thus looked to characterize differences in decidual NKs in first versus repeated pregnancies. We discovered a population unique to repeated pregnancies, which possesses a novel transcriptome and epigenetic signature, characterized with high expression levels of the receptors NKG2C and LILRB1. Activation of these receptors leads to increased production and secretion of IFNγ and VEGFa, the latter found to support vascular sprouting and trophoblast-tumor growth. We propose that this population represents NK “memory” of pregnancy, and have named these cells Pregnancy Trained decidual NK cells (PTdNKs). We further suggest that the precursors of PTdNKs are found in the endometrium. PTdNKs may prove useful in understanding and treating disorders of poor placentation.

Proteomic analysis of NK cell-derived extracellular vesicles.

Project description:Natural killer (NK) cells contribute to immunosurveillance and first-line defense in the control of tumor growth and metastasis diffusion. NKEVs are constitutively secreted, are biologically active, reflect the protein and genetic repertoire of their originating cells and exert anti-tumor activity in vitro and in vivo. NKEVs from tumor-conditioned NK cells interact with naïve NK cells promoting their cytotoxic activity. In cancer NK cells exhibit profound defects in degranulation ability, a status probably reflected by their NKEVs. Hence, NKEVs could contribute to improve cancer therapy by interacting with tumor and/or immune cells at the same time sensing the actual NK cell status in cancer patients. Here we investigated the role of NKEVs in stimulating the immune system and developed an immune enzymatic test (NKExoELISA) to sense the systemic NK cell status by measuring plasma NK-derived exosomes through combined capture of exosomes, expressing typical EV (tsg101) and NK cell (CD56) markers. We analyzed by LC-MS/MS the protein content from NKEVs evaluating proteins differentially expressed in exosomes (NKExo), vescicles (NKMV) and total cell extract (Tot extr) from parental NK cells. Proteomic data confirmed the presence of many EV markers and detected several proteins involved in immune response, cell adhesion and complement biological processes.

Gene expression analysis for CD56- T, NK, CD56+ T cells, and iNKT cells

Project description:A small subset of T cells also expresses kiler-cell immunoglobulin-like receptors (KIRs). We find that KIR+ T cells primarily reside in the CD56+ T population. However, little is known on how these cells are different from the conventional CD56- T, NK, and iNKT cells. We used microarray profiling to compare and determine the distinctive differences of CD56+ T cell and its KIR subsets when compared to the conventional CD56- T, NK and iNKT cells. Lymphocyte subsets were sorted from human peripheral blood mononuclear cells with FACSAriaII (BD Biosciences, San Jose, CA) using anti-CD3, anti-CD56, anti-CD14, anti-KIR2DL1, anti-KIR2DL2/3, anti-KIR3DL1 and anti-TCRValpha24 antibodies. The purity of CD3+CD56- T cells, CD3-CD56+ NK cells, CD3+CD56+ T cells, KIR-CD3+CD56+ T cells, and KIR+CD3+CD56+ T cells were more than 98% in all experiments. The purities of iNKT cells for TCRValpha24 and CD1d-tetramer were >95% and >90%, respectively. RNA pre-amplification, labeling and hybridization on Human Genome U133Plus 2.0 GeneChip array were performed in the St. Jude Hartwell Center for Bioinformatics & Biotechnology microarray core facility according to the manufacturer’s instructions (Affymetrix, Santa Clara, CA).
