Project description:NK cells from healthy donors were isolated from peripheral blood and stimulated overnight with IL-12/15/18 to induce a memory-like phenotype. After 7 days of culture, the phenotype and degranulation potential of CIML NK cells was characterized in two distinct NK cell subsets: CD16+/CD56+ and CD16−/CD56. Finally, NK cell subsets were purified using fluorescence-activated cell sorting (FACS) and subjected to high-throughput multiplexed quantitative proteomics.

Project description:Pooled purified peripheral blood derived CD56dimCD16+ NK, CD56brightCD16- NK and in vitro activated CD56+CD16+ NK subsets obtained from 9 healthy donors were analyzed for gene expression pattern. Each pooled NK subset sample was hybridized in replicates (A and B). Keywords: other

Project description:It is known that natural killer (NK) cells are a heterogeneous population of functionally distinct NK cell subsets. Here we report on different genomic, phenotypic and functional properties of human NK cell subsets derived from peripheral blood, thymus and bone marrow. NK cell subpopulations were defined via expression of CD56 and CD16.

Project description:We sorted Eomes-negative NK cells (CD3- CD56+ CXCR6- CD16-) and Eomes-positive NK cells (CD3- CD56+ CXCR6+) from total leukocytes isolated from the perfusion fluid of five healthy human livers destined for transplantation. Total RNA was extracted from sorted cells, cDNA generated and RNASeq performed.

Project description:The aim of the study was to investigate the activation of human NK cells by IL2 through analyzing the global gene expression at different time points (0, 2, 8 and 24 hours) after culture with the cytokine IL2 at 100 IU/ml. NK cells with the CD56+/CD16+ and CD3- phenotype were negatively selected by immunomagnetic beads and re-examined by flow-cytometry to ensure greater than 90% purity . Keywords: resting and IL2 activated NK cells(time series)

Project description: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.

Project description:There is limited knowledge on the origin and development of the ample spectrum of human NK cells, particularly of specialized NK subsets. Here, we characterized the NK cell progeny of CD34+DNAM-1bright CXCR4+ precursors that reside in healthy bone marrow and circulate in the peripheral blood (PB) of patients with chronic infections/inflammation. including HIV, HCV or HCMV reactivation after HSC transplantation. Unlike conventional CD34+ precursors they rapidly differentiated in vitro into cytotoxic, IFNγ-secreting CD94/NKG2C+KIR+CD57+ maturing NK cell progenies with HCMV-inhibiting activity. Progeny characterization led also to identification of an additional new PB Lin-CD56-CD16+ precursor giving rise to the same CD94/NKG2C+KIR+CD57+ maturing NK cell progenies. Microarray analysis of NK cell progenies revealed a signature compatible with maturing adaptive NK cells. In vivo circulation of multiple common lymphocyte precursors with rapid development to NKG2C+ NK cell progeny is steadily occurring and may thus be a crucial resource for the prompt control of HCMV. We used microarray to compare the transcriptional profiles of human NKG2C+ NK cells derived from i) CD34+DNAM1brightCXCR4+ precursors, ii) Lin-CD34-CD16+CD56- precursors, iii) peripheral blood.

Project description:Identification of genes differentially expressed between human CD14+CD16- and CD16+ monocyte-derived macrophages generated in the presence of either GM-CSF (termed GM14 and GM16, respectively) or M-CSF (termed M14 and M16, respectively) Human peripheral CD14+CD16- and CD16+ blood monocytes from three independent healthy donors (D1, D2 and D3) were isolated by positive selection from peripheral blood mononuclear cells (PBMC) using magnetic separation systems (MACS, Miltenyi Biotec). Briefly, PBMC were first incubated with MACS anti-CD56 antibody conjugated to paramagnetic microbeads in order to eliminate the NK (CD16+) cell fraction. NK-depleted PBMC were further incubated with MACS anti-CD16 antibody to isolate CD16+ monocytes. CD56-CD16- PBMC were finally incubated with MACS anti-CD14 antibody to obtain the CD14+CD16- monocyte fraction. Monocytes were cultured for 7 days in medium containing either GM-CSF or M-CSF. Total RNA from each condition was extracted using the RNeasy kit (Qiagen) and hybridized to an Agilent Human Whole Genome (4x44) Oligo Microarray. All experimental procedures were performed following manufacturer instructions.

Project description:T-BET and EOMES are key transcription factors in the development of mature NK cells in mice. However, the role of these transcription factors during human NK cell development is less well understood. Therefore, we overexpressed T-BET or EOMES in human umbilical cord blood-derived hematopoietic progenitor cells (HPC) and cultured them in vitro in an NK cell differentiation model. On day 21 of culture mature stage 4 (CD56+CD94+CD16-) and stage 5 (CD56+CD94+CD16+) NK cells from T-BET or EOMES overexpression and control cultures were sorted, whereafter mRNA was isolated and transcriptome analysis was performed by RNA sequencing. Evaluation of the transcriptome in mature NK cells with T-BET or EOMES overexpression could reveal the molecular mechanisms of how T-BET and EOMES play a role in terminal NK cell maturation.

Profiling of the epigenetic changes during T-BET or EOMES overexpression in mature NK cells revealed new insights in the regulatory role of T-BET and EOMES during terminal NK cell maturation.
