Project description:BackgroundTriggering receptor expressed on myeloid cells 2 (TREM2) signaling is considered to regulate anti-inflammatory responses in macrophages, dendritic cell maturation, osteoclast development, induction of obesity, and Alzheimer's disease pathogenesis. However, little is known regarding the effect of TREM2 on natural killer (NK) cells.ResultsHere, we demonstrated for the first time that CD3-CD122+NK1.1+ precursor NK (pNK) cells expressed TREM2 and their population increased in TREM2-overexpressing transgenic (TREM2-TG) mice compared with that in female C57BL/6 J wild type (WT) mice. Both NK cell-activating receptors and NK cell-associated genes were expressed at higher levels in various tissues of TREM2-TG mice than in WT mice. In addition, bone marrow-derived hematopoietic stem cells (HSCs) of TREM2-TG mice (TG-HSCs) successfully differentiated into NK cells in vitro, with a higher yield from TG-HSCs than from WT-HSCs. In contrast, TREM2 signaling inhibition by TREM2-Ig or a phosphatidylinositol 3-kinase (PI3K) inhibitor affected the expression of the NK cell receptor repertoire and decreased the expression levels of NK cell-associated genes, resulting in significant impairment of NK cell differentiation. Moreover, in melanoma-bearing WT mice, injection of bone marrow cells from TREM2-TG mice exerted greater antitumor effects than that with cells from WT control mice.ConclusionsCollectively, our data clearly showed that TREM2 promoted NK cell development and tumor regression, suggesting TREM2 as a new candidate for cancer immunotherapy.

Project description:Uterine Natural Killer (uNK) cells regulate essential developmental processes at the maternal-fetal interface during early pregnancy. Uterine NK cell functions are tightly regulated during early placentation to stimulate trophoblast invasion and remodel uterine spiral arteries. Access to human 1st and 2nd trimester uterine tissues allowed us to investigate the transcriptional changes in uNK cells during the early stages of early human pregnancy. Microarray analysis identified 97 upregulated genes in 2nd compared to 1st trimester purified uNK cells of which the majority (61%) clustered as interferon-stimulated-genes (ISG), with ISG15 and ISG20 being upregulated profoundly. Type I interferons (IFNα/β), but not type II interferon (IFNɣ) increased expression of the identified interferon target genes ISG15 and ISG20 in uNK cells in vitro. Moreover, the cytokine-like protein ISG15 stimulated in vitro trophoblast invasion. Second trimester uNK cells promoted trophoblast invasion in vitro, whereas both 1st and 2nd trimester uNK cells stimulated endothelial tube formation. IFNα but not IFNβ stimulation of 1st trimester uNK cells enhanced their capacity to promote trophoblast invasion. In conclusion, the uNK cell interferon transcriptome is upregulated during the 2nd trimester allowing uNK cells to promote trophoblast invasion. Type I interferon signaling regulates uNK cell-induced trophoblast invasion via induction of effector molecules like ISG15. First trimester uNK cells can be induced to act like second trimester uNK cells by IFNα with respect to promotion of trophoblast invasion. Key words: Gene expression profiling ■ uterine natural killer cells ■ extravillous trophoblast invasion ■ interferon alpha ■ ISG15

Project description:MicroRNAs (miRNAs) play important roles in regulating immune response of natural killer (NK) cells, a critical effectors against malignancy and infection. Here, miRNAs profiles of goat uterine NK (uNK) cells and peripheral blood NK (pNK) cells were examined, and a novel miRNAs, miR-1, that is lowly expressed in uNK cells compared to pNK cells were identified. We further demonstrated that miR-1 directly target TWEAK gene in NK cells, a negative regulator of NK cell cytotoxicity. Moreover, our data revealed that an increased miR-1 expression was observed in uNK cells incubated with somatic cell nuclear transfer (SCNT) conditioned medium compared to those incubated with in vitro fertilization (IVF) conditioned medium, and an inverse correlation was detected between miR-1 expression and TWEAK mRNA and protein expression in both groups. Interestingly, miR-1 mediated suppression of TWEAK in uNK cells in response to SCNT conditioned medium incubation was accompanied with an increased cytotoxicity and IFN-γ expression compared to control group. Furthermore, miR-1 inhibitor transfection abrogate the enhanced cytotoxicity of uNK cells incubated with SCNT conditioned medium, which was accompanied with an increased TWEAK expression. Taken together, our results demonstrated that TWEAK regulated by miR-1 may play a key role in regulating goat uNK cells cytotoxicity and IFN-γ expression levels. In particularly, miR-1 mediated suppression of TWEAK may involved in the increased cytotoxicity of uNK cells in response to SCNT embryo incubation. These results provide a resource for studying the roles of miRNAs in goat NK cell biology and contribute to a better understanding of the physiologic significance of miRNAs in the regulation of NK cell function.

Project description:The endometrium contains a distinct population of immune cells consisting of 70% natural killer (NK) cells that undergo cyclic changes during the menstrual cycle. However, how these uterine NK (uNK) cells interact with uterine stromal cells (SC) remains unclear. We therefore investigated the paracrine effect of medium conditioned by uNK cells on the gene expression profile of endometrial SC in-vitro using a cDNA Microarray. Our results, verified by real-time PCR and ELISA, reveal that soluble factors from uNK cells substantially alter endometrial SC gene expression. The largest group of up-regulated genes found were chemokines and cytokines, including IL-15 and IL-15Rα. The latter could produce a niche for uNK cells allowing proliferation within and recruitment into the uterus, as seen in bone marrow. In addition, the most abundantly up-regulated genes, including IL-8, CCL8 and CXCL1 have also been shown to be stimulated by contact of SC with trophoblast, suggesting that uNK cells work synergistically to support the initial trophoblast migration during implantation. Overall this study demonstrates for the first time the paracrine communication between uNK cells and uterine SC, and adds to the understanding of how the uterine immune system contributes to the changes seen within the cycling endometrium.

Keywords: Response of endometrial stromal cells to uNK conditioned medium This study was designed to identify the response of non-decidualised stromal cells from the endometrium, to soluble factors secreted by uterine NK cells. Endometrial stromal cells were isolated from 7 patients and treated with control medium or medium conditioned by uterine Nk cells. THE 'REF' COLUMN ON EACH ARRAY IS THE SIGNAL PRODUCED BY A COMMON REFERNCE RNA SAMPLE THAT WAS LABELLED AS A SINGLE BATCH SAMPLE AND HYBRIDISED TO ALL THE ARRAYS- IT IS A 'COMMON REFERENCE'. THE 'TEST' SAMPLE COMPRISES EACH INDIVIDUAL SAMPLE OF CELLS TREATED AS DESCRIBED IN THE SERIES SUBMISSION. FOR EXAMPLE; SAMPLE Y1 (gsm2435820) IS RNA FROM PATIENT 1 TREATED WITH CONTROL MEDIUM, SAMPLE G1 (GSM245371) IS RNA FROM PATIENT 1 TREATED WITH NK CONDITIONED MEDIUM THESE TWO SAMPLES THEREFORE FORM A PAIR- IE CELLS FROM THE SAME PATIENT TREATED WITH CONTROL OR NK-CONDITIONED MIDIUM. Y2,G2 ARE FROM PATIENT 2, ETC

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.

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.
