Project description:Innate lymphoid cells (ILCs) are recently identified lymphocytes that limit infection and promote tissue repair at mucosal surfaces. However, the pathways underlying ILC development remain unclear. Here we show that the transcription factor NFIL3 directs the development of a committed bone marrow precursor that differentiates into all known ILC lineages. NFIL3 was required in the common lymphoid progenitor (CLP), and was essential for the differentiation of CLP, a bone marrow cell population that gives rise to all known ILC lineages. Clonal differentiation studies revealed that CXCR6+ cells within the CLP population differentiate into all ILC lineages but not T- and B-cells. We further show that NFIL3 governs ILC development by directly regulating expression of the transcription factor TOX. These findings establish that NFIL3 directs the differentiation of a committed ILC precursor that gives rise to all ILC lineages and provide insight into the defining role of NFIL3 in ILC development. This experiment is to compare gene expression profiles between wild-type and Nfil3-/- common lymphoid progenitor (CLP) cells to identify genes regulated by NFIL3. There are 6 samples in this experiment, including 3 biological replicates for wild-type CLPs and 3 biological replicates for Nfil3-/- CLPs. All mice used are on the C57BL/6 background.

Project description:Regulatory T (Treg) cells maintain self-tolerance in lymphoid tissues, and specialized Treg cells accumulate and perform homeostasis and regenerative functions in non-lymphoid tissues. A common differentiation pathway of homeostasis-promoting Treg cells in non-lymphoid tissues from a putative precursor remains elusive. By using novel reporter mice and single-cell RNA-sequencing, we identified precursor stages of the IL-33 receptor ST2-expressing non-lymphoid tissue Treg population in spleen and lymph nodes. Molecular profiling of these precursors versus mature tissue Treg cells revealed their sequence of differentiation on a single-cell level. Global chromatin profiling of non-lymphoid tissue Treg cells and progenitor populations revealed a stepwise acquirement of open chromatin accessibility at tissue Treg genes. Mechanistically, we identified and validated the basic leucine zipper transcription factor, ATF-like (Batf) as a driver of the molecular tissue Treg program. Understanding this tissue program will help to harness regenerative properties of tissue Treg cells for therapy.

Project description:Natural killer (NK) cells can be grouped into distinct subsets that are localized to different organs and exhibit different capacity to secrete cytokines and mediate cytotoxicity. Despite these hallmarks that reflect tissue-specific specialization in NK cells, little is known about the factors that control the development of these distinct subsets. The basic leucine zipper transcription factor nuclear factor interleukin 3 (Nfil3; E4bp4) is essential for bone marrow-derived NK cell development but it is not clear whether Nfil3 is equally important for all NK cell subsets nor how it induces NK lineage commitment. Here we show that Nfil3 is required for the formation of Eomesodermin (Eomes)-expressing NK cells, including conventional medullary and thymic NK cells, whereas TRAIL+ Eomes- NK cells develop independent of Nfil3. Loss of Nfil3 during the development of bone marrow-derived NK cells resulted in reduced expression of Eomes and, conversely, restoration of Eomes expression in Nfil3-/- progenitors rescued NK cell development and maturation. Collectively, these findings demonstrate that Nfil3 drives the formation of mature NK cell by inducing Eomes expression and reveal the differential requirements of NK cell subsets for Nfil3.

Project description:Most transcription factors possess at least one long intrinsically disordered transactivation domain that binds to a variety of co-activators and co-repressors and plays a key role in modulating the transcriptional activity. Despite the crucial importance of these mechanisms, the structural and functional basis of transactivation domain in yet poorly understood. Here, we focused on ATF4/CREB-2, an essential transcription factor for cellular stress adaptation. We found that the N-terminal region of the transactivation domain is involved in transient long-range interactions with the basic-leucine zipper domain. In vitro phosphorylation assays with the protein kinase CK2 show that the presence of the basic-leucine zipper domain is required for optimal phosphorylation of the transactivation domain. This study uncovers the intricate coupling existing between the transactivation and basic-leucine zipper domains of ATF4 and highlights its potential functional relevance.

Project description:We assessed the role of basic leucine zipper transcription factor ATF-like 2 (Batf2), particularly its positive transcriptional activities via TLR signals. Because TLR7 agonists are clinically used against tumors and have proven effective as antitumor drugs, we assessed effect of Batf2 on the responses to the TLR7 ligand (R848).
