Transcriptome analysis of in vitro hematopoietic stem cells (HSC) and stage 3 (ST3) NK cell progenitors cells expressing a IRF2-specific shRNA.

ABSTRACT: To investigate the function of IRF2 in the regulation of natural killer (NK) cell differentiation, we established in vitro NK cell differentation cultures starting with cordblood derived HSC in which IRF2 has been knocked down with shRNA by lentiviral transduction. We then performed transcriptome analysis of the HSC population at day 3 and ST3 population at day 7.

Proteomic characterization of CD56posCD57 NK cell subsets

Project description:NK cells are lymphocytes that provide a first defense against viral infections and cancer. They act (i) cytotoxic by killing virus-infected and tumorigenic cells and (ii) immune regulatory by releasing cytokines and chemokines. These innate immune cells are commonly further classified as CD56bright and CD56dim NK cells. Former studies confirmed immune regulatory CD56bright NK cells as progenitors of cytotoxic CD56dim NK cells. CD57 was previously described as T cell marker for senescence and terminal differentiation. Recent studies detected CD57+ and CD57- NK cells among the CD56dim NK cell population and suggested a fully mature developmental status for CD57+ NK cells. The recent NK cell maturation model includes CD34+ hematopoietic stem cells (HSC), which develop into CD56bright NK cells, later into CD56dimCD57- and finally into terminally maturated CD56dimCD57+ (1) (2) (3). The molecular mechanisms of human NK cell differentiation and maturation remain unknown to this date. We performed for the first time a proteomic analysis of these distinct developmental stages of human primary NK cells, isolated from overall 10 healthy human blood donors. CD56bright NK cells versusCD56dim and CD56dimCD57- versus CD56dimCD57+ NK cells were analyzed by using quantitative peptide sequencing, which revealed individual protein signatures (3400 proteins) of these different NK cell developmental stages. Notably, our data support the current NK cell differentiation model by highlighting both strong distinctions between CD56dim/bright NK cells and close relationships between CD57+/- NK cells on the proteomic level. Among the most prominent and conserved regulated proteins, we detected myosin IIa, Calvasculin and Calcyclin with very similar expression patterns. We investigated their sub-cellular localization and observed specific recruitment- and accumulation-events at the NK cell immunological synapse (NKIS) after NK activation.

IRF2 regulates macrophages apoptosis through a STAT1/3 and Caspase-1-dependent mechanism

Project description:Using microarray gene expression profiling of liver RNA samples rerived from IRF2+/+ and IRF2-/- mice treated with saline or LPS, we identified >40 genes that were significantly down-regulated in IRF2 -/- mice, including STAT3 which has been reported to regulate apoptosis. Keywords: compound treatment design We compared gene expression in IRF2+/+ and IRF2-/- mice treated with Saline or LPS for 3 or 6 hours. Two repeats were done for the LPS treatments. The total number of arrays is 6.

Expression Profiling of Primary Human Proerythroblasts (ProEs) After IRF2, IRF6, and MYB shRNA Knockdown

Project description:IRF2, IRF6, and MYB are candidate regulators of human erythropoiesis. We here examine primary CD34+ hematopoietic stem/progenitor cells (HSPCs)-derived erythroid progenitors with control, IRF2, IRF6, or MYB shRNA lentiviral transduction prior to differentiation. Gene expression microarray profiling datasets for MYB shRNA and control shRNA were obtained from Gene Expression Omnibus (GEO) under accession number GSE25678. The data were analyzed together with the datasets obtained in this study. Primary maturing adult erythroblasts were generated ex vivo from CD34+ hematopoietic stem/progenitor cells (HSPCs) using a serum-free two-phase liquid culture system. CD34+ HSPCs were transduced with lentiviruses containing shRNAs against IRF2 or IRF6 gene, selected and differentiated to proerythroblasts (ProEs). Cells were harvested at day 5 of differentiated and total RNA were extracted. This was used to hybridize to Affymetrix expression arrays using the HG-U133 Plus 2.0 platform.

SMAD4 impedes conversion of NK cells into ILC1-like cells by curtailing non-canonical TGFb signaling (human data sets)

Project description:Among the features that distinguish type 1 innate lymphoid cells (ILC1s) from NK cells is a gene signature indicative of TGFb-family cytokine imprinting. To assess the impact of TGFb family cytokines on ILC1 differentation, we examined SMAD4- a transcription factor that facilitates the signaling pathway common to all TGFb family cytokines-was specifically ablated in ILCs and NK cells. While SMAD4 deficiency did not affect ILC1 differentation, NK cells paradoxically aquired an ILC1-like gene signature and were incapable of controlling tumor metastasis and viral infection. We used microarray to compare the transcriptional differences between human blood NK cells. NK cells from a patient with a deleterious SMAD4 mutation or control NK cells were cultured overnight with either IL-2 alone or TGFb1 and IL-2.

IRF2 ChIP seq in mouse intestinal stem cells (ISCs)

Project description:To examine whether IRF2, a negative regulator of IFN signaling, constitutively represses IFN signaling by binding IFN-inducible gene loci in ISCs, we performed a genome-wide chromatin immunoprecipitation/DNA sequencing (ChIP-Seq) analysis of IRF2 in Lgr5 ISCs. We identified 381 binding peaks in these cells, including well-known IFN-inducible genes. Motif analysis showed significant enrichment of consensus-binding motifs for IRF transcription factors within these peaks. Within IRF2-occupied genes in ISCs, we identified 204 of experimentally validated IFN-inducible genes from Interferome database, and 10.8% of them were overlapped with the genes upregulated by type I IFN stimulation in ISCs. These findings indicated for the first time that IRF2 constitutively bound and repressed the sterile IFN signaling at the level of ISCs.
