Project description:To investigate changes in chromatin accessibility over time, we differentiated Th9 cells in vitro from naïve T cells from human and murine sources, and followed them over an extended time course, during which they gained and then lost capacity for IL-9 production
Project description:To test whether human in vitro primed Th9 cells recapitulate the core pathogenic Th2 cell phenotype, we differentiated naïve T cells into Th1 (IL-12), Th2 (IL-4), Th9 (IL-4+TGF-β), and iTreg (TGF-β). After 7 days transcriptomic profiling by bulk RNA-seq was performed.
Project description:To investigate changes in gene expression over time, we differentiated Th9 cells in vitro from naïve T cells from human and murine sources, and followed them over an extended time course, during which they gained and then lost capacity for IL-9 production We then performed gene expression profiling analysis using data obtained from RNA-seq in cells from 2 different human donors and from 2 mice at 4 time points.
Project description:To investigate changes in chromatin accessibility over time, we differentiated Th9 cells in vitro from naïve T cells from human and murine sources, and followed them over an extended time course, during which they gained and then lost capacity for IL-9 production We then performed Chromatin immunoprecipitation DNA-sequencing (ChIP-seq) for histone modifications H3K4me1, K3K4me3, and H3K27Ac in cells from 2 different human donors and from 2 mice at 4 time points.
Project description:We assessed the global transcriptional changes driven by STING activation with the cyclic dinucleotide 2'3'-cGAMP TH1 and TH9 cells polarized in vitro for 16h and 48h. Our data indicated that STING activation led to an upregulation of Type I Interferon, Interferon Stimulated Genes and pro-inflammatory molecule production that was maintained over time. Furthermore, not only STING activation enhanced the transcription of TH1 and TH9 main effector cytokines (respectively Ifng and Il9) but they also also globally enhanced their differentiation programs.
