Project description:Lymphoid tissue inducer (LTi) cells are regarded as a subset of innate lymphoid cells (ILCs). However, these cells are not derived from the ILC common progenitor, which generates other ILC subsets and is defined by the expression of the transcription factor PLZF. Here we examined transcription factor(s) determining the fate of LTi progenitor versus non-LTi ILC progenitor. Conditional deletion of Gata3 resulted in the loss of PLZF+ non-LTi progenitors but not the LTi progenitors that expressed the transcription factor RORγt. Consistently, PLZF+ non-LTi progenitors expressed high amounts of GATA3 whereas GATA3 expression was low in RORγt+ LTi progenitors. The generation of both progenitors required the transcriptional regulator Id2, which defines the common helper-like innate lymphoid progenitor, but not cytokine signaling. Nevertheless, low GATA3 expression was necessary for the generation of functionally mature LTi cells. Thus, differential expression of GATA3 determines the fates and functions of distinct ILC progenitors.

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.

Project description:Transcription factor (TF) reporter mice have proved integral to the characterization of murine innate lymphoid cell (ILC) development and function. Here, we implemented a CRISPR/Cas9-generated combinatorial reporter approach for the simultaneous resolution of several key TFs throughout ILC development in both the fetal liver and adult bone marrow. We demonstrate that the Tcf7-expressing early innate lymphoid progenitor (EILP) and the common helper innate lymphoid progenitor (CHILP) both contain a heterogeneous mixture of committed ILC and Lymphoid Tissue-inducer (LTi) precursors, rather than a shared precursor to these lineages. Moreover, the earliest specified precursor to the LTi lineage was identified upstream of these populations, prior to the expression of Tcf7. These findings match dynamic changes in chromatin accessibility associated with the expression of key TFs (ie. Gata3 and Rorc), highlighting the distinct origins of ILC and LTi lineages at the epigenetic and functional levels, and provide a revised map for ILC development.

Project description:Lymphoid tissue inducer (LTi) cells, known to be critical for the generation of secondary lymphoid tissues, are the founding member of innate lymphoid cells (ILCs). However, how the development and functions of this ILC subset are regulated is far from clear. In this study, we discovered a striking role of the transcription factor TCF-1 in the development of Peyer’s patches (PPs) but not lymph nodes (LNs). Despite TCF-1 is critical for ILC development at multiple stages, we found normal development of LTi cells in TCF-1-deficient mice indicating that dysfunction of these LTi cells led to the deficiency in Peyer’s patches formation. Through bulk and single cell RNA-Seq, we found differential gene expression patterns between LTi cells from the PPs, LNs and the small intestine laminal propria (siLP), and an important role of TCF-1 in regulating the expression of lymphotoxin (LT) specifically in PP LTi cells. Mechanistically, TCF-1 may regulate Lta indirectly through promoting the expression of GATA3, a critical transcription factor in regulating LTi functions. LTβR agonist injection during the embryonic stage partially rescued the formation of PPs in the TCF-1-deficient mice. Thus, a dose effect of LT expression in LTi cells regulated by TCF-1 contributes to a differential regulation of organogenesis of distinct secondary lymphoid structures.

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.

Project description:The ets transcription factor ELF5 specifies the differentiation of mammary progenitor cells to establish the milk-secreting lineage. ER- and poor prognosis basal breast cancers arise from this progenitor cell and these cancers express high levels of Elf5. Knockdown of ELF5 expression in basal breast cancer cell lines, or forced expression in luminal breast cancer cell lines, resulted in reduced cell proliferation. Transcript profiling and chromatin immunoprecipitation revealed that the transcriptional activity of ELF5 specified the gene expression patterns that distinguish basal from luminal breast cancer, including suppression of FOXA1, GATA3 and ER, key estrogen-action genes. Tamoxifen treatment of luminal MCF7 cells upregulated Elf5 expression and cells that acquired resistance to Tamoxifen became dependent on ELF5 for proliferation. ELF5 is a regulator of breast cancer cell proliferation, transcriptionally specifies the basal molecular subtype and is utilised by ER+ breast cancer cells to escape proliferative arrest caused by Tamoxifen. Elf5 was induced via doxycycline treated PyMT mouse tumours, in triplicate
