Neuroprotective protein ADNP-dependent histone remodeling complex promotes Th2 immune cell differentiation (ChIP-Seq)

ABSTRACT: Type-2 immune responses are critical in tissue homeostasis, anti-helminth immunity and allergy. Th2 cells produce interleukin (IL)-4, IL-5 and IL-13 from the type-2 gene cluster under regulation by transcription factors (TFs) including GATA3. To better understand this system we performed CRISPR-Cas9 screens targeting 1131 TFs during Th2 cell differentiation. We discovered that ADNP is indispensable for immune reactions to allergen. Mechanistically, ADNP performs a previously unappreciated role in gene activation forming a critical bridge in the transition from pioneer TFs to chromatin remodelling by recruiting CHD4 and BRG1. Although GATA3 and AP-1 bound the type-2 cytokine locus in the absence of ADNP, they were unable to initiate histone acetylation or DNA accessibility, resulting in highly impaired type-2 cytokine expression. Similar ADNP-dependent regulation was observed for the Maf and Il4ra genes which are known regulators of Th2 differentiation. Our results demonstrate an important role for ADNP in promoting immune cell specialization.

Transcription profiling of mouse ADNP knockout vs wild type

Project description:The putative transcription factor, activity-dependent neuroprotective protein (ADNP) is a zinc finger and homeodomain - like profile containing protein. ADNP knockout mice die at day 9 of gestation. To reveal ADNP-associated pathways, a 22,690- Affymetrix probe array was used on ADNP knockout and control embryos.

PMID: 12888219 [PubMed - indexed for MEDLINE] Experiment Overall Design: To identify downstream target genes of ADNP, we examined global gene expression profiles of whole E9 knockout embryos (KO - ADNP -l-), their wild-type (WT - ADNP +l+ ) and their heterozygous (H - ADNP âl+ ) littermates, using the Affymetrix Murine Genome 430A oligonucleotide microarrays. Gestation day 9 was chosen as it is the period at which embryos lacking ADNP exhibit distinct morphological and developmental changes prior to degeneration and in uterus absorption. Total RNA was extracted from four ADNP knockout embryos, four normal embryos and six heterozygous embryos. A pool of two genotype identical littermates was used on seven different arrays (pooling of two embryos was necessary to obtain enough RNA on each of the gene microarrays).

Bcl11b- and GATA3-mediated gene regulation in Th2 cells

Project description:GATA-binding protein 3 (GATA3) acts as the master transcription factor for type 2 T helper (Th2) cell differentiation and function. However, it is still elusive how GATA3 function is precisely regulated in Th2 cells. Here, we report that the transcription factor B cell lymphoma 11b (Bcl11b), a previously unknown component of GATA3 transcriptional complex, is involved in GATA3-mediated gene regulation. Bcl11b binds to GATA3 through protein-protein interaction, and they co-localize at many important cis-regulatory elements in Th2 cells. The expression of type 2 cytokines, including IL-4, IL-5 and IL-13, is up-regulated in Bcl11b-deficient Th2 cells both in vitro and in vivo; such up-regulation is completely GATA3-dependent. Genome-wide analyses of Bcl11b- and GATA3-regulated gene (from RNA-Seq), co-binding pattern (from ChIP-Seq), and Bcl11b-mediated epigenetic changes (in H3K27ac and DHSs) suggest that GATA3/Bcl11b complex is involved in limiting Th2 gene expression, as well as in inhibiting non-Th2 gene expression. Thus, Bcl11b controls both GATA3-mediated gene activation and repression in Th2 cells.

Tissue-restricted adaptive type-2 immunity is orchestrated by OX40L expression on group 2 innate lymphoid cells

Project description:We investigated the transcriptional profiles of lung ILC2, Th2 and Treg (Gata3+ and -) cells from naïve and IL-33-treated mice. This experiment accompanies our manuscript, where we showed that IL-33-dependent accumulation of adaptive type-2 immune cells (Th2 and Treg) was dependent on OX40L expression by ILC2.

Priming for Th2 differentiation requires IL-2-mediated induction of IL-4 receptor alpha chain expression

Project description:Th2 cells enable humoral immunity and host-defense to parasites. Whereas IL-4 drives Th2 differentiation and IL-2 is important later in this process by augmenting IL4 chromatin accessibility, we demonstrate that IL-2 serves an essential early role in regulating IL-4Rα expression by inducing binding of Stat5a and Stat5b to the IL4ra locus, with sustained binding during Th2 differentiation. Although IL-4 induces IL-4Rα expression, TCR-induced IL-4Rα expression was unexpectedly normal in ILr-/- but profoundly diminished in IL2-/- T cells. Remarkably, enforced IL-4Rα expression rescued Th2 differentiation in IL2-/- cells. These results reveal a novel function for IL-2, with IL-2 via Stat5 providing an early signal for IL4ra induction, thereby priming cells for Th2 differentiation and promoting/maintaining IL-4Rα expression in Th2-committed cells. ChIP-seq experiments for Stat5a and Stat5b with an IgG control experiment for 8hr, 13hr and 2 rounds of Th2 differentiation. Keywords: ChIP-seq, Illumina, Th2 differentiation, Stat

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.
