RNA-Seq analysis of mouse group 2 innate lymphoid cells (ILC2s) cultured with IL-33, IFN-g, and IL-27

ABSTRACT: Purpose: We found that IFN-g and IL-27 had suppressive effects on ILC2s cultured with IL-33. The goal of this study is to clarify the expressions of RNA induced by IFN-g and IL-27 in ILC2s. Methods: ILC2s were isolated from fat-asociated lymphid clusters (FALC) of wild-type mice. They were cultured with IL-33 (10ng/ml), IL-33 + IFN-g (10ng/ml), or IL-33 + IL-27 (10ng/ml) for 48hrs. RNA was isolated by Allprep DNA/RNA Micro Kit (QIAGEN), and cDNA libraries were prepared by TruSeq RNA Sample Preparation kits v2 (Illumina) according to the manufacturerâs low sample protocol. A HiSeq 1500 system (Illumina) was used for 50 single-end bases (50SE)ãsequencing. Results: Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence, then mapped to the reference genome (mm9) using Bowtie2 v2.1.0 and TopHat2 v2.0.8. The transcript abundances were estimated as FPKM (fragments per kilobase of exon million fragments mapped) value using Cufflinks v2.1.1. We found that both IL-27 and IFN-g upregulated the expression of STAT1 and IRF1 which are regulated downstream of IFN-g receptor signaling, but there was no difference in the expression of GATA3, a critical transcription factor for ILC2 functions. Conclusions: Our study represents the detailed differences of RNA expressions by RNA-seq technology. RNA-Seq analysis of ILC2s cultured with IL-33 (10ng/ml), IL-33 + IFN-g (10ng/ml), or IL-33 + IL-27 (10ng/ml) for 48hrs.

Human ILC2 cells stimulated with IL-25, IL-33, or TSLP

Project description:ILC2 cells are a newly described cell type whose biology and contribution to disease are poorly understood. ILC2 cells are activated by allergens, viral infection, and/or epithelial damage via IL-33 and IL-25. ILC2 cells require IL-2, IL-7, IL-25 and IL-33 for their survival and expansion. In mice, ILC2s produce multiple mediators primarily associated with type 2 inflammation (IL-13, IL-5, IL-4, IL-6, IL-9, IL-10, GM-CSF, amphiregulin). ILC2 cells may contribute to the pathology of asthma through multiple mediators that include IL-13-independent pathways. Our goal is to compare transcriptional profiles of IL-33- or IL-25-activated ILC2 cells from blood to characterize these cells and to identify marker(s) that can be utilized to detect them in human tissue. ILC2 cells (Lineage negative, CRTH2+, CD161+, CD127+) were purified from human blood of 5 different donors by flow cytometry. The ILC2 yield ranged from 20,000 to 165,000 cells per donor (0.001-0.008% WBC). Purified ILC2s were expanded in vitro in the presence of IL-2, IL-7, IL-33 and IL-25 (each at 50 ng/ml) for 7-10 days. Expanded cells maintained the ILC2 phenotype (Lineage negative, CRTH2+, CD161+, CD127+). The cells were rested for 2 days in the presence of 1 ng/ml IL-2 and IL-7 and then treated in the presence of 1 ng/ml IL-2 and IL-7 with either media control, IL-25 (50 ng/ml), IL-33 (50 ng/ml), and/or TSLP (50 ng/ml) in combination, for 6 or 24 hours. Whole RNA was isolated via the RNeasy kit (Qiagen). Stratagene Universal Human Reference RNA was used as the reference.

Proteome of group 2 innate lymphoid cells (ILC2s) stimulated with IL33 and TL1A

Project description:We analyzed the total proteome of group 2 innate lymphoid cells (ILC2s) after different stimulation with interleukin-33 (IL-33), a cytokine playing a critical role in human asthma, and TL1A, a TNF-family cytokine also known to activate ILC2s. Upon combined stimulation with IL-33 plus TL1A, we show that lung ILC2s produce high amounts of IL-9 and acquire a transient ‘ILC9’ phenotype. This phenotype is characterized by simultaneous production of large amounts of type 2 cytokines (IL-5, IL-13 and IL-9), induction of the IL-2 receptor CD25 (Il2ra), and of the transcription factors IRF4, JunB and BATF, that form immune-specific complexes known to induce IL-9 expression.

Mouse ILC2 cells from wild-type or Gfi1-KO animals

Project description:Innate type-2 lymphocytes (ILC2s) are a newly described cell type whose biology and contribution to disease are poorly understood. We are interested in investigating the role of the transcription factor Gfi1 in ILC2s, which appear to be a prominent source of IL-5 and IL-13 during type-2 immune responses. We have compelling evidence demonstrating a critical role for Gfi1 in the development and effector state of ILC2s. We would like to elucidate the molecular role of Gfi1 in ILC2s by identifying Gfi1-regulated genes by microarray analysis. Gfi1+/+ or Gfi1GFP/GFP (a GFP cassette has been 'knocked-in' to the Gfi1 locus and thus functions both as a surrogate for Gfi1 promoter activity and as a loss-of-function allele) mice were injected with IL-25 once daily for 4 days. On day 5, ILC2s (Lin-/Sca-1+/ICOS+/CD127+/c-Kit+) were sorted from the mesenteric lymph nodes of Gfi1+/+ (3 mice/sample were pooled together) or Gfi1-/- mice (6 mice/sample were pooled together) and cultured for 6 days in RPMI 1640, 10% FBS, Gln, P/S, 2ME, IL-2 (50ng/ml), IL-7 (10ng/ml), and IL-25 (50ng/ml). Whole RNA was harvested on day 6 via the RNeasy kit (Qiagen).

The transcription factor GATA3 is critical for the development of all IL-7Ra-expressing innate lymphoid cells (ILCs) and maintenance of type 2 ILCs

Project description:Innate lymphoid cells (ILCs) play critical roles during innate immune responses to pathogens and lymphoid organ development. IL-7Ra+ ILC subsets, similar to T helper (Th) cell subsets, produce distinctive effector cytokines. The molecular control of IL-7Ra+ ILC development and maintenance has yet to be dissected. Here we report that GATA3 is indispensable for the development of all IL-7Ra+ ILC subsets and T cells. Gata3 conditional deficient mice have no lymph nodes and are susceptible to Citrobactor rodentium infection. Genome-wide gene analyses indicate that GATA3 regulates similar set of cytokines and receptors in ILC2s and Th2 cells and is critical for the maintenance of ILC2s. Thus, GATA3 plays parallel roles in establishing and regulating both adaptive and innate lymphocytes. To identify GATA3 regulated genes in type 2 innate lymphoid cells by tamoxifen-mediated acute deletion of Gata3 gene.

Transcription factor Bcl11b controls identity and function of mature innate lymphoid cells type II

Project description:Type-2 innate lymphoid cells (ILC2s) promote anti-helminth responses and contribute to allergies. Though Bcl11b has been previously considered a T-lineage identity transcription factor (TF) that restrains the innate-cell genetic programs, we report here that Bcl11b is highly expressed in mature ILC2s and acts upstream of the key ILC2 TFs Gfi1, Gata-3, and of IL-33 receptor IL1rl1 (T1ST2). Additionally, Bcl11b-/- ILC2s de-repressed Rorγt, Ahr and IL-23 receptor, normally expressed in type-3 ILCs (ILC3s). Consequently, Bcl11b-/- ILC2s lost ILC2 functions and gained ILC3 functions, expanding in response to the protease allergen papain, however producing IL-17 and IL-22, and not IL-5 and IL-13, causing lung neutrophilia rather than eosinophilia, and diminished mucus production. Our results broaden Bcl11b's role from a T-cell only TF, and establishes that Bcl11b sustains mature ILC2 genetic and functional programs and lineage fidelity through positive regulation of essential ILC2 TFs and negative regulation of pivotal ILC3 TFs. RNA-seq analysis on sorted ILC2s from the mLNs of Bcl11bF/F Cre-ERT2 and wildtype mice at steady state following tamoxifen mediated deletion of Bcl11b

Transcription profiling by array of human dendritic cells after Poly(I:C)-based or PGE2-based maturation

Project description:Generation of human monocyte-derived DCs Peripheral blood mononuclear cells (PBMC) were isolated by Ficoll density centrifugation from buffy coats or whole blood of healthy donors and resuspended in serum-free medium (CellGro, CellGenix GmbH, Freiburg, Germany), supplemented with penicillin (50U/ml)/streptomycin (50?g/ml). Cells were plated at a density of 1-1,25 e6/cm2 in T-25 flasks and allowed to adhere for 2h at 37oC. Non-adherent cells were removed by washing twice with PBS and frozen as T cell source for stimulation experiments. Adherent monocytes were differentiated into immature DC with 1000U/ml GM-CSF and 50ng/ml IL-4 (""im DC""). Unless stated otherwise, cytokines were purchased from CellGenix GmbH, Freiburg, Germany. Cytokines were replenished on day 3. Maturation was achieved by incubation with either IL-1?; (10ng/ml), IL-6 (1000U/ml), TNF?; (10ng/ml) and PGE2 (1?g/ml, ICN, Aurora, Ohio, USA) (""PGE2-DC"") or IL-1?; (25ng/ml), IFN?; (3000U/ml, Schering-Plough, Brussels, Belgium), IFN?; (1000U/ml Strathmann Biotech AG), TNF?; (50ng/ml) and poly(I:C) (a synthetic, double-stranded RNA, 20ng/ml, Sigma-Aldrich, Taufkirchen, Germany) (""poly(I:C)-DC"") on day 6 for 48 hours Total RNA was isolated from DC before and after cytokine maturation

Group 3 innate lymphoid cells continuously require the transcription factor GATA3 after commitment

Project description:GATA3 is indispensable for the development of all IL-7RÎ±-expressing innate lymphoid cells (ILCs) and maintenance of type 1 ILCs (ILC1s) and type 2 ILCs (ILC2s). However, the importance of low GATA3 expression in type 3 ILCs (ILC3s) is still elusive. Here, we report that GATA3 regulates homeostasis of ILC3s by controlling IL-7RÎ± expression. In addition, GATA3 is critical for the development of NKp46+ ILC3 subset partially through regulating the balance between T-bet and RORÎ³t. Genome-wide analyses indicate that while GATA3 positively regulates CCR6+ and NKp46+ ILC3 subset-specific genes in respective lineages, it negatively regulates CCR6+ ILC3-specific genes in NKp46+ ILC3s. Furthermore, GATA3 regulates IL-22 production in both CCR6+ and NKp46+ ILC3s. Thus, low GATA3 expression is critical for the development and function of ILC3 subsets. To identify GATA3 regulated genes in total ILC3s with RNA-Seq; To identify unique genes expressed by CCR6+ ILC3 or NKp46+ ILC3 and GATA3 regulated genes within these two ILC3 subsets with RNA-Seq; To identify GATA3 direct binding sites in ILC3s, ILC2s and Th2 cells with ChIP-Seq.

IL-33 markedly induces murine eosinophil gene transcription via autocrine IL-4-dependent and -independent mechanisms

Project description:Eosinophils are major effector cells in type 2 inflammatory responses and become activated in response to IL-4 and IL-33, yet the molecular mechanism remains unclear. We examined the direct effect of these cytokines on eosinophils and demonstrated that murine eosinophils respond to IL-4 and IL-33 by phosphorylation of STAT-6 and NFkB, respectively. RNA sequencing analysis of murine eosinophils indicated that IL-33 regulates 519 genes, whereas IL-4 regulates only 28 genes, including 19 IL-33-regulated genes. Interestingly, IL-33 induced eosinophil activation via two distinct mechanisms, IL-4 independent and IL-4 secretion/auto-stimulation dependent. Anti-IL-4 or anti-IL-4Ra antibody-treated eosinophils, as well as Il4- or Stat6-deficient eosinophils, had attenuated protein secretion of a subset of IL-33-induced genes, including Retnla and Ccl17. However, the induction of most IL-33-regulated transcripts (e.g. Il6 and Il13) was IL-4 independent and blocked by NFkB inhibition. Indeed, IL-33 induced the rapid release of pre-formed IL-4 protein from eosinophils by an NFkB-dependent mechanism. Thus, we have identified a novel activation pathway in murine eosinophils that is induced by IL-33 and differentially dependent upon IL-4. These data suggest that IL-4 plays a critical role in auto-amplification of IL-33-induced eosinophil activation and could be a potential target for therapeutic approaches in IL-33-related eosinophil-associated diseases. Low density bone marrow derived murine eosinophils were generated in culture over the period of 14 days. Eosinophils were activated by either IL-33 or IL-4 at 10 ng/ml for 1hr and 4hr. RNA was collected and subjected to next generation sequencing.

Quantitative phosphoproteomic analysis of IL-33 mediated signaling

Project description:Interleukin-33 (IL-33) is a novel member of the IL-1 family of cytokines that plays diverse roles in the regulation of immune responses. IL-33 exerts its effects by binding to a heterodimeric receptor complex consisting of interleukin-1 receptor like 1 (IL1RL1) and an accessory receptor protein IL-1RAcP resulting in the production and release of proinflammatory cytokines. A detailed understanding of the signaling pathways activated by IL-33 remains elusive. To elucidate IL-33 mediated signaling, we performed a global quantitative phosphoproteomic analysis using stable isotope labeling by amino acids in cell culture. Employing anti-phosphotyrosine antibodies and titanium dioxide-based enrichment strategies, we identified 6,207 phosphorylation sites mapping to 2,013 phosphoproteins of which more than 185 phosphosites are regulated by IL-33 stimulation. Our findings will greatly expand the understanding of IL-33 signaling and provide novel therapeutic targets for IL-33/IL-33R-associated diseases in humans.
