ABSTRACT: This SuperSeries is composed of the SubSeries listed below. To determine the molecular regulation of different subsets of ILC3s by Setd2, small intestinal NKp46- ILC3s (Thy1highCD45low NKp46-) and NKp46+ ILC3s (Thy1highCD45low NKp46+) were purified from littermate Rag1-/-;Setd2f/f or Rag1-/-;Rorc-cre;Setd2f/f mice. Cells were subjected to RNA-seq and ATAC-seq analyses.

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.

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

Project description:GATA3 is indispensable for the development of all IL-7Rα-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-7Rα expression. In addition, GATA3 is critical for the development of NKp46+ ILC3 subset partially through regulating the balance between T-bet and RORγt. 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.

Transcriptome comparison between Zbtb46-deficient and -sufficient group 3 innate lymphoid cells

Project description:We unexpectedly identify one unique subset of group 3 innate lymphoid cells (ILC3s) that co-expresses Zbtb46, a transcription factor that specifies conventional dendritic cells (cDCs). Zbtb46 is robustly expressed by CCR6+ lymphoid tissue inducer (LTi)-like ILC3s that are developmentally and phenotypically distinct from cDCs. To determine the function of Zbtb46 in ILC3s, we performed RNA sequencing on CCR6+ ILC3s sorted from the large intestine of Zbtb46 f/f and Rorc Cre Zbtb46 f/f mice at steady state.

A cis-element at the Rorc locus regulates the development of type 3 innate lymphoid cells

Project description:As an important early source of IL-17A and IL-22 in immune responses, type 3 innate lymphoid cells (ILC3s) are critically regulated by the transcription factor retinoic-acid-receptor-related orphan receptor gamma t (RORγt). Previously, we have identified a crucial role of the conserved non-coding sequence 9 (CNS9), located at +5,802 to +7,963 bp of the Rorc gene, in directing T helper 17 differentiation and related autoimmune disease. However, whether cis-acting elements regulate RORγt expression in ILC3s is unknown. Here we show that CNS9 deficiency in mice not only decreases ILC3 signature gene expression and increases ILC1-gene expression features in total ILC3s, but also leads to generation of a distinct CD4+NKp46+ ILC3 population, though the overall numbers and frequencies of RORγt+ ILC3s are not affected. Mechanistically, CNS9 deficiency selectively decreases RORγt expression in ILC3s, which thus alters ILC3 gene expression features and promotes cell-intrinsic generation of CD4+NKp46+ ILC3 subset. Our study thus identifies CNS9 as an essential cis-regulatory element controlling the lineage stability and plasticity of ILC3s through modulating expression levels of RORγt protein.

Group 3 innate lymphoid cells amplify YAP1-driven small intestinal repair

Project description:Ror gamma t-deficient mice lack group 3 Innate Lymphoid Cells (ILC3s) and as a result have increased tissue damage and diminished tissue repair in response to insult. To identify repair programs associated with ILC3 presence the transcriptomes of small intestinal stem cells exposed to damage in the presence or absence of ILC3 were compared. Small intestinal damage was induced in Ror gamma t-deficient Lgr5 reporter mice and littermate controls. Small intestinal epithelial stem cells were purified at days 1 and 4 after damage and subjected to RNA sequencing.

Gene expression profiling of small intestine (SI) NKp46+RORgt+ and NKp46+RORgt- Innate Lymphoid Cells (ILCs)

Project description:The aim of this study was to analyze the global transcriptional profiles of small intestine (SI) Innate Lymphoid Cells (ILCs) expressing the NK cell marker NKp46. Based on differential expression of the RORgt transcription factor SI NKp46+ ILCs can be divided in NKp46+RORgt- and NKp46+RORgt+ cells. While NKp46+RORgt- cells produce IFN-g, like conventional Natural Killer (NK) cells, NKp46+RORgt+ cells secrete IL-22, like Lymphoid Tissue inducer (LTi) cells. We compared the global transcriptional profiles of both NKp46+RORgt- and NKp46+RORgt+ cells to conventional splenic NK cells and to SI NKp46-RORgt+ cells, which contain adult LTi cells. By following this approach, we showed that SI NKp46+RORγt- ILCs correspond to SI NK cells. We also identified a transcriptional program conserved in adult SI NKp46+RORγt+, NKp46-RORγt+ ILCs and fetal LTi. The various ILC cell populations analyzed in this study were isolated from C57BL/6 RORc(gt)+/GFP reporter mice. SI NKp46+RORγt- (NKp46+GFP-) cells, SI NKp46+RORγt+ cells (NKp46+GFPlow and NKp46+GFPhigh cells) and NKp46-RORγt+ ILCs, including adult LTi cells , were sorted by flow cytometry from CD3- lamina propria cells of small intestine (SI) of RORc(γt)+/GFP reporter mice . Splenic NKp46+RORγt- (NKp46+GFP-) cells were also sorted as the reference for conventional NK cells. Two replicates of each populations were produced and analyzed.

Antibody Fc-receptor common gamma chain FcεR1γ stabilizes cell surface receptors in group 3 innate lymphoid cells and promotes anti-infection immunity

Project description:Group 3 innate lymphoid cells (ILC3s) are crucial for maintaining mucosal homeostasis and regulating inflammatory diseases, but the molecular mechanisms governing their phenotype and function are not fully understood. Here, we showed that ILC3s highly expressed Fcer1g gene, which encodes the antibody Fc-receptor common gamma chain (FcεR1γ). Genetic perturbation of FcεR1γ led to the absence of critical cell membrane receptors NKp46 and CD16 in ILC3s. Alanine scanning mutagenesis identified two residues in FcεR1γ that stabilize its binding partners. FcεR1γ expression in ILC3s was essential for effective protective immunity against bacterial and fungal infections. Mechanistically, FcεR1γ influenced the transcriptional state and proinflammatory cytokine production of ILC3s, relying on the CD16-FcεR1γ signaling pathway. Overall, our findings highlight the significance of FcεR1γ as an adaptor protein that stabilizes cell membrane partners in ILC3s and promotes anti-infection immunity.
