Satb1 Orchestrates the Expression of Lineage-Specifying Genes in Post-Selection Thymocytes

Project description:T-cell receptor (TCR) signaling by MHC class-I and -II induces thymocytes to acquire cytotoxic and helper fates via induction of Runx3 or ThPOK transcription factors, respectively. The mechanisms by which TCR signaling is translated into transcriptional programs for each cell fate remain elusive. We show that a genome organizer, Satb1, activates genes for lineage-specifying factors, including ThPOK and Runx3, in post-selection thymocytes. Indeed, Satb1-deficient thymocytes are partially redirected to inappropriate T lineages after MHC selection. Although Satb1 is dispensable for maintaining ThPOK in CD4+ T cells, it is necessary for restraining expression of the Treg factor FoxP3. Collectively, our findings demonstrate that Satb1 shapes the primary T-cell pool by initially directing lineage-specific transcriptional programs and subsequently balancing effector versus regulatory subsets via FoxP3 repression.

Transcriptome analysis of SATB1- and SATB1+ Hematopoietic stem cells.

Project description:Hematopoietic stem cells (HSCs) are now recognized as a heterogeneous population in self-renewing and differentiation capabilities. However, fundamental mechanisms governing the heterogeneity remain uncertain. We here show that special AT-rich sequence-binding protein 1 (SATB1), a global chromatin organizer, is involved in the mechanisms. Analyzing hematological lineage-restricted SATB1 knock out mice proved that SATB1 is indispensable for both self-renewal and normal differentiation of adult HSCs. Using SATB1/Tomato knock-in mice, we subdivided HSCs according to SATB1 intensity. Culture experiments and RNA-sequencing revealed essential differences between SATB1- and SATB1+ HSCs regarding lineage potential.

Co-Transplantation of Barcoded Lymphoid-Primed Multipotent (LMPP) and Common Lymphocyte (CLP) Progenitors Reveals a Major Contribution of LMPP to the Lymphoid Lineage.

Project description:T cells have the potential to maintain immunological memory and self-tolerance by recognizing antigens from pathogens or tumors. In pathological situations, failure to generate de novo T cells causes immunodeficiency resulting in acute infections and complications. Hematopoietic stem cells (HSC) transplantation constitutes a valuable option to restore proper immune function. However, delayed T cell reconstitution is observed compared to other lineages. To overcome this difficulty, we developed a new approach to identify populations with efficient lymphoid reconstitution properties. To this end, we use a DNA barcoding strategy based on the insertion into a cell chromosome of a lentivirus (LV) carrying a non-coding DNA fragment named barcode (BC). These will segregate through cell divisions and be present in cells' progeny. The remarkable characteristic of the method is that different cell types can be tracked simultaneously in the same mouse. Thus, we in vivo barcoded LMPP and CLP progenitors to test their ability to reconstitute the lymphoid lineage. Barcoded progenitors were co-grafted in immuno-compromised mice and their fate analyzed by evaluating the BC composition in transplanted mice. The results highlight the predominant role of LMPP progenitors for lymphoid generation and reveal valuable novel insights to be reconsidered in clinical transplantation assays.
