Project description:The development of all dendritic cells (DCs) including antigen-presenting conventional DCs (cDCs) and cytokine-producing plasmacytoid DCs (pDCs) is controlled by the growth factor Flt3 ligand (Flt3L) and its receptor Flt3. We genetically dissected this common Flt3L-driven pathway of DCs differentiation using CRISPR/Cas9-based dropout screening in a Flt3L-dependent progenitor cell line. Genome-wide screening identified multiple regulators of DC differentiation including the glycosylphosphatidylinositol transamidase complex and arginine methyltransferase Carm1, whose role was confirmed in vivo. It also showed that negative regulators of mTOR signaling, including the subunits of TSC and GATOR1 complexes, restricted progenitor growth but enabled DC differentiation, demonstrating that a TSC- and GATOR1-mediated shutdown of mTOR is required for the process. An orthogonal screen focused on transcriptional regulators showed that Trim33 (TIF-1g) is required for DC differentiation. Conditional targeting in vivo revealed an essential role of Trim33 in the development of all DCs, but not of monocytes or granulocytes. In particular, inducible deletion of Trim33 caused a rapid loss of all DC progenitors, pDCs and the cross-presenting cDC1 subset. The loss of Trim33 from DC progenitors caused spontaneous interferon and inflammatory response, aberrant induction of macrophage-specific genes, and failure to induce DC differentiation program. Collectively, these data elucidate common mechanisms that control Flt3L-driven differentiation of the entire DC lineage, and identify Trim33 as its essential regulator.

Project description:Investigation of immune cell differentiation and function is limited by shortcomings of suitable and scalable experimental systems. Although forced expression of certain Hox genes allows immortalization of hematopoietic progenitor cells, their differentiation potential is limited to select myeloid lineages. Here we show that an estrogen-regulated form of Hoxb8 that is retrovirally delivered into bone marrow cells can be used along with FLT3 ligand to conditionally immortalize early hematopoietic progenitor cells (Hoxb8-FL). Hoxb8-FL cells have lost self-renewal capacity and the ability to adopt megakaryocyte/ erythroid lineage fates, but sustain myeloid and lymphoid differentiation potential. Hoxb8-FL cells differentiate in vitro and in vivo into different myeloid and lymphoid cell types, including macrophages, granulocytes, dendritic cells and B- and T-lymphocytes, which are phenotypically and functionally indistinguishable from their primary counterparts. Given the simplicity to generate Hoxb8-FL cells and their unlimited proliferative capacity, this system provides unique opportunities to investigate cell differentiation and immune cell functions.

Project description:To get insight into TRIM33 functions, TRIM33 ChIP-seq was carried out in murine macrophage cell line (RAW) and in bone marrow-derived macrophages (BMDM). The results showed that, in addition to its role in hematopoietic differentiation, TRIM33 may modulate PU.1 transcriptional activity during macrophage development and/or activation.To characterize the role of TRIM33 in macrophages, we bred TRIM33fl/fl mice with Lyz-Cre mice where the Cre recombinase gene is under the regulatory sequences of the Lyz gene that is expressed only in mature myeloid cells. Bone marrow cells from LyzCre/Trim33+/+ mice and LyzCre/Trim33flox/flox mice were differentiated in macrophages and treated during 0h, 4h, 12h and 24h with LPS. Using ChIP-seq, we provide a link between TRIM33 binding and H3K4me3 spreading on inflammatory genes in macrophages. Chromatin immunoprecipitations of TRIM33 and H3K4Me3 followed by multiparallel sequencing performed in murine bone marrow-derived macrophages (BMDM).
