Comparative gene expression of CD34+ human hematopoietic progenitor cells upon knockdown of STAT5

Project description:The objective of the study is to identify the genes regulated by STAT5 in very primitive human hematopoietic stem progenitor cells (HSPCs). We used Affymetrix Human Genome U133 Plus 2.0 microarrays to investigate gene expression in human CD34+CD38- HSPC upon expression of STAT5 or control luciferase shRNA-encoding vectors.

Nfix is a novel regulator of murine hematopoietic stem and progenitor cell survival

Project description:Hematopoietic stem cells are both necessary and sufficient to sustain the complete blood system of vertebrates. Here we show that Nfix, a member of the nuclear factor I (Nfi) family of transcription factors, is highly expressed by hematopoietic stem and progenitor cells (HSPC) of murine adult bone marrow. Although shRNA mediated knockdown of Nfix expression in Lineage-Sca-1+c-Kit+ HSPC had no effect on in vitro cell growth or viability, Nfix-depleted HSPC displayed a significant loss of colony forming potential, as well as short- and long-term in vivo hematopoietic repopulating activity. Analysis of recipient mice 4-20 days post-transplant revealed that Nfix-depleted HSPC establish in the bone marrow but fail to persist due to increased apoptotic cell death. Gene expression profiling of Nfix-depleted HSPC reveals that loss of Nfix expression in HSPC is concomitant with a decrease in the expression of multiple genes known to be important for HSPC survival, such as Erg, Mecom, Mpl and Prdm16. These data reveal that Nfix is a novel regulator of HSPC survival post-transplantation and establish, for the first time, a role for Nfi genes in the regulation of this cellular compartment. 3 NFIX depleted samples are compared to 3 wt samples

Single-Cell Transcriptomic Analysis Reveals Neutrophil as Orchestrator during β-Glucan-Induced Trained Immunity in a Teleost Fish

Project description:We establish a trained immunity activation model in turbot (Scophthalmus maximus) by training with β-glucan in vivo. Through single cell RNA-sequencing analysis, we annotate 16 clusters of immune cells and blood cells from head kidney and spleen, and successfully characterize that neutrophils exhibit distinguished feature of trained immunity.

Genome-wide analysis of mDC transcriptional response to cyclic glucan

Project description:Analysis of transcriptional profiles in mDC sorted from apheresed PBMC and stimulated for 6 hours with cyclic glucan or LPS. The hypothesis tested is that cyclic glucan induces maturation and T cell-activation transcripts in human mDC. Total RNA extracted from mDC sorted from apheresed PBMC and activated for 6 hours with cyclic glucan or LPS.

The role of HIF-1 in beta-glucan induced response in myeloid cell

Project description:beta-glucan induced glycolysis in HIF-1 depedent manner. We reported that beta-glucan injection in mice led to upregulated glycolysis. HIF-1a plays a major role in this process. Mice receives beta-glucan via ip for 4 days. Splenocytes were isolated for RNA sequencing.

Yeast beta-glucan diets alter bone-marrow derived macrophage function

Project description:Fungal beta-glucans are major drivers of trained immunity which increases long-term protection against secondary infections. Heterogeneity in beta-glucan source, structure and solubility alters interaction with the phagocytic receptor Dectin-1 and could impact strategies to improve trained immunity in humans. Using a panel of diverse beta-glucans we describe the ability of a specific yeast-derived whole-glucan particle (WGP) to reprogramme metabolism and thereby drive trained immunity in human monocyte-derived macrophages in-vitro and mice bone-marrow in-vivo. Presentation of pure, non-soluble, non-aggregated WGPs led to the formation of the Dectin-1 phagocytic synapse with subsequent lysosomal mTOR activation, metabolic reprogramming and epigenetic rewiring. Intraperitoneal or oral administration of WGP drove bone-marrow myelopoiesis and improved mature macrophage responses, pointing to therapeutic and food-based strategies to drive immune training. Thus, the investment of a cell in a trained response relies on specific recognition of beta-glucans presented on intact microbial particles through stimulation of the Dectin-1 phagocytic response.
