Project description:The mechanisms by which dendritic cells (DCs) induce differentiation of naïve CD4+ T cells along the Th2 lineage is not well understood given that DCs themselves do not produce IL-4. In the present study, we undertook a microarray approach to identify genes involved in the induction of Th2 differentiation by DCs treated with a Th2-skewing adjuvant cholera toxin (CT). In the microarray analysis, murine bone marrow derived immature DCs were treated with CT. Of particular interest was tthe significant upregulation of the expression of c-kit. The upregulation of c-kit on DCs is critical for the induction of a Th2 response. Keywords: cholera toxin, bone marrow derived dendritic cells, gene expression array-based (RNA / spotted DNA/cDNA) Murine bone marrow cells were cultured in the presence of GM-CSF (10 ng/ml) for 6 days . On day 6 the cells were harvested and purified using magnetically labeled anti mouse CD11c+ beads . The DCs were stimulated with CT (1 ug/ml) for 24 hours and the RNA was isolated.

Project description:We cultured bone marrow derived dendritic cells from WT and CD11c KO mice. Then, a group of bone marrow dendritic cells were stimulated with LPS overnight. We obtained bone marrow derived dendritic cells with or without LPS stimulation and analyzed proteomics profiles.

Project description:Heme is an erythrocyte-derived toxin that drives disease progression in hemolytic anemias. During hemolysis, specialized bone marrow-derived macrophages with a high heme-metabolism capacity orchestrate disease adaptation by removing damaged erythrocytes and heme-protein complexes from the blood and supporting iron recycling for erythropoiesis. Here, we performed single-cell RNA sequencing with RNA velocity analysis of GM-CSF-supplemented mouse bone marrow cultures to assess myeloid differentiation under heme stress. We found that heme-activated NRF2 signaling shifted the differentiation trajectories of cells towards antioxidant, iron-recycling macrophages at the expense of dendritic cells, as these cells were selectively deficient in heme-exposed bone marrow cultures. Heme eliminated the capacity of GM-CSF-supplemented bone marrow cultures to activate antigen-specific T cells. The generation of functionally competent dendritic cells was restored by NRF2 loss. The heme-induced phenotype was reproduced in hemolytic mice with sickle cell disease and spherocytosis and associated with reduced dendritic cell functions in the spleen. Our data provide a novel mechanistic underpinning how hemolytic stress may provoke hyposplenism-related secondary immunodeficiency, which is a critical determinant of mortality in patients with genetic hemolytic anemias.
