Project description:Mouse spleen CD4+CD44LowCD62LHigh cells were stimulated with 2ug/ml anti-CD3(eBioscience), 2ug/ml anti-CD28 (eBioscience) in the presence (Th17 condition) or absence (Th0 condition) of hTGFb-1 (1ng/ml eBioscience), mouse IL-6(10ng/ml eBioscience). Cells were collected after 24 hourÕs culture using RNAeasy columns (Qiagen) for total RNA isolation. Isolated total RNA from Th0 and Th17 conditioned cells were submitted for the microarray gene transcription comparison analysis using Affymetrix Mouse 430A 2.0 array chips.
Project description:Stem cell memory T cells can be defined as the memory T cell subsets with naïve T cell phenotypes and stem cell-like properties. We find that Notch signaling converts activated T cells into stem cell memory T (TSCM) cells by OP9-DL1 feeder cell coculture. Based on gene expression profile analysis, we provide evidence that these cells represent distinct characters with central memory T (TCM) cells and naïve T cells with effector molecules and transcription factors. TSCM cells induced by Notch cluster closer to TCM cells than naïve T cells, and display similar phenotypes to TCM phenotype in terms of effector molecules and transcription factors, but the gene expressions of TSCM cells are entirely lower than that of TCM cells.
Project description:We compared CD8 TCM cells specific for a CMV epitope (pp65495-503) and an influenza A virus (IAV) epitope (M158-66) of the same healthy adults and identified genes whose expression are altered in CMV-specific compared to IAV-specific TCM cells.
Project description:Transcriptional profiling of CD8 Tcm cells comparing untreated control cells to 16 hour norepinephrine treated cells. The goal was to examine the impact of norepinephrine treatment on CD8 Tcm cell global gene expression compared to untreated cells, and also to examine changes that occurred in resting cells and activated cells 24 and 72 hours after stimulation with CD3/28 beads. Two-conditional experiment: Control vs. NE treated CD8 Tcm cells. Biological replicates: 3 replicates for 0 hour and 24 hours, and 2 replicates for 72 hours. Each sample consisted of pooled RNA from 3 different donors.
Project description:This project evaluates the immune regulating properties of maple syrup extract in spleen samples utilizing an LPS induced peritonitis mouse model.
