Project description:To finely dissect the dynamic changes in the epigenome and chromatin state during T cell activation, we utilized the Jurkat cell line as a model and performed ChIP-seq on both resting and anti-CD3/CD28-stimulated Jurkat cells, targeting various histone modifications (H3K27ac, H3K4me1, H3K4me3, H3K27me3), RNA PolII, and CTCF.
Project description:The majority of genetic risk variants associated with autoimmune diseases are located in chromatin regions that are accessible during T cell stimulation. To systematically investigate the dynamic changes in chromatin accessibility during T cell activation, we utilized the Jurkat cell line as a model and performed ATAC-seq on both resting and anti-CD3/CD28-stimulated Jurkat cells.
Project description:To meticulously explore how local chromatin architecture influences T cell activation, we conducted high-resolution regional capture Hi-C by designing tiling capture probes that span the CD28, CTLA4, and ICOS genes along with their distal regulatory sequences (chr2:204300000-205000000, GRCh37) in both resting and stimulated Jurkat cells.
Project description:To investigate the dynamics of gene expression during T cell activation and identify essential genes responsive to stimulation, we conducted RNA sequencing on both resting and stimulated Jurkat cells.
Project description:Fe-IMAC phosphoproteomics using TMT 11plex for quant, of Jurkat T cells stimulated with CD3 and CD28 agonist antibodies for 0, 3, 9, or 27 minutes.
