Project description:CD70TG mice are a model for sterile chronic immune activation and develop Anemia of Inflammation, which is dependent on the production of Ifng by effector CD4 and CD8 T cells. We used microarrays to identify Ifng-dependent differentially expressed genes that could account for the erythropoietic defect. CD71+ cells were MACS-enriched from the bone marrow of WT, CD70TG, IFNg-/- and CD70TG*IFNg-/- male mice of 10-12 weeks of age (3 mice per genotype group).
Project description:ATAC-seq profiling of Nfat5 KO and wild type macrophages derived from bone marrow (primary cells), treated or not with Lipopolysaccharide (LPS).
Project description:To comprehensively understand how dendritic cells (DCs) are reprogrammed by lung fibroblasts- and their derived COX-2/PGE2, we employed lung fibroblasts isolated from WT or Ptgs2-/- mice, and collect their conditioned medium (CM) to stimulate the ex vivo cultured bone marrow (BM)-derived DCs (BM-DCs), with the PGE2 treatment as a control. After the treatment, BM-DCs were harvested for RNA extraction and the transcriptional profiles were analyzed by RNA sequencing (RNA-seq).
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:WT control or IFNAR deficient bone marrow derived macrophages were stimulated with IFNb, TLR3, IFNg, TLR4, and TLR4+IFNg ligands for 48 h.
Project description:Dhh negatively regulates multiple stages of erythrocyte differentiation. In Dhh-deficient bone marrow, the common myeloid progenitor (CMP) population was increased, but differentiation from CMP to granulocyte/macrophage progenitor was decreased, and the mature granulocyte population was decreased, compared with wild-type (WT). In contrast, differentiation from CMP to megakaryocyte/erythrocyte progenitor was increased, and the megakaryocyte/erythrocyte progenitor population was increased. In Dhh-deficient spleen and bone marrow, BFU-Es and erythroblast populations were increased compared with WT. During recovery of hematopoiesis after irradiation, and under conditions of stress-induced erythropoiesis, erythrocyte differentiation was accelerated in both spleen and bone marrow of Dhh-deficient mice compared with WT. To investigate possible mechanisms for its regulation of erythropoiesis we carried out RNAsequencing on Facs-sorted erythroblast population II (CD71+Ter119+) cells from Dhh-/-, Dhh+/- and WR mice.
