Comparison of transcriptional profiles of (1) intestinal ILC3s isolated from WT and IL-17D-deficient mice; (2) CD93+ILC3s and CD93-ILC3s from WT mice

Project description:IL-17D/CD93 axis was essential for ILC3s hemostasis. In order to further understand how IL-17D-CD93 axis regulate ILC3s function, we conducted RNA-seq analysis of ILC3s.

Gene expression analysis of genes differentially expressed between CD93-ko mice and wild-type mice in post ischemic mice brain tissue

Project description:To further decipher CD93-dependent pathways, we compared global expression profiles of ischemic (ipsilateral) hemispheres of CD93-deficient mice (CD93-ko) with expression profiles of wild-type mice. Total RNA obtained from CD93-ko and WT mice at different time points after cerebral ischemia and from untreated brain tissue

Metoclopramide treatment blocks CD93-signaling mediated self-renewal of chronic myeloid leukemia stem cells

Project description:Purpose: The goal of this study was to compare the transcriptome of FACS-purified bone marrow BL/6 (WT) or CD93-/- (KO) LSKs and BL/6 (WT) or CD93-/- (KO) LSCs. We also compared the transcriptome of FACS-purified bone marrow LSCs isolated from BL/6 mice previously treated with MCP or Veh in vivo. Methods: Transcriptomic analysis of CD93-proficient and deficient bone marrow LSKs and CML LSCs or CML LSCs upon treatment with MCP or Veh, were assessed in biological replicates using Illumina. qRT–PCR validation was performed using SYBR Green assays. Results: We mapped around 30 million sequence reads per sample to the mouse genome (GRCm38 - mm10) and identified expressed transcripts in studied samples. RNA-seq data confirmed stable expression of known housekeeping genes. Differentially expressed genes among conditions were identified with a fold change ≥1.5 and FDR p-value <0.05. Conclusions: Our study represents the first detailed transcriptome analysis of CD93-proficient and deficient bone marrow LSKs and LSCs isolated from BM of naïve and CML mice generated by RNA-seq. technology. Our results show that CD93-signaling triggers stem cell maintenance- and cell proliferation-promoting signaling pathways in CML LSCs. In addition, we showed transcriptome analysis of FACS-purified bone marrow LSCs isolated from BL/6 (WT) mice which were previously treated with MCP or Veh in vivo. Our results show that MCP treatment suppresses the stem cell maintenance- and cell proliferation-promoting signaling pathways in CML LSCs.

Analyses of ILC3s from the mesenteric lymph nodes (LN)

Project description:Analyses of ILC3s in Rorc floxed control and Id2iÎ?RORÎ³t mice following daily treatments of tamoxifen for two weeks. Cells were sort purified as lineage negative, CD127+ CD90.2+ CCR6+ ST2- CCR6+ ILCs were sorted from the mesenteric LN of Rorc floxed control and Id2iÎ?RORÎ³t mice following daily treatments of tamoxifen for two weeks.

Chromatin accessibility landscapes of WT (Rag1-/-) and BATF KO (Rag1-/-Batf-/-) ILC3s sorted from small intestine [ATAC-seq]

Project description:Group 3 innate lymphoid cells (ILC3s) are crucial for the maintenance of host-microbiota homeostasis in gastrointestinal mucosal tissues. The mechanisms that maintain lineage identity of intestinal ILC3s, and ILC3s-mediated orchestration of microbiota and mucosal T cell immunity are elusive. Here, we identified BATF as a gatekeeper of ILC3s homeostasis in the gut. Depletion of BATF in ILC3s resulted in excessive interferon-γ production, dysbiosis, aberrant T cell immune responses and spontaneous inflammatory bowel disease (IBD), which was considerably ameliorated by removal of adaptive immunity or antibiotic treatment. Mechanistically, BATF directly regulates ILC3s identity by globally shapes chromatin landscape of ILC3s. BATF directly binds to the cis-regulatory elements of type 1 effector genes, restrains their chromatin accessibility and inhibits their expression. Conversely, BATF promotes chromatin accessibility of genes involved in MHCII antigen processing and presentation pathways. Collectively, our findings reveal BATF is a promising candidate to maintain ILC3s stability and coordinate ILC3s–mediated control of intestinal homeostasis.

Microarray data from human cultured ILC3s

Project description:Innate lymphoid cells (ILCs) are tissue-resident lymphocytes subdivided into ILC1s, ILC2s and ILC3s based on core regulatory programs and signature cytokines secreted. ILCs exhibit functional plasticity: for instance, human IL-22-producing ILC3s convert into IFN-γ-producing ILC1-like in vitro. Whether this conversion occurs in vivo is unclear. Using flow cytometry, mass cytometry and scRNAseq, here we found that ILC3s and ILC1s occupy opposite ends of a spectrum including discrete subsets in human tonsils. RNA velocity suggested strong directionality toward ILC1s for one ILC3-ILC1 intermediate cluster. Clonal analysis revealed graded ability of ILC3-ILC1 subsets to convert into ILC1-like cells. When examined in humanized mice, ILC3 acquisition of ILC1 features showed tissue-dependency. In chromatin studies, Aiolos emerged as a nuclear factor that cooperates with Tbet to repress evolutionarily conserved regulatory elements active in ILC3s. The human intestine also exhibited an ILC3–ILC1 transitional population. We conclude that conversion of ILC3s to ILC1-like occurs in vivo in human tissues, and that tissue factors and Aiolos are crucial for this process.
