Project description:miRNA profiling of resting and activated T cells Two condition experiment, resting versus activated T cells, measured pooled samples from three independent stimulations
Project description:To investigate miRNA expressions of miRNA upon activation. In vitro-differentiated human NK cells were freshly incubated in the presence of IL15 after 24h deprivation of IL-15. The cells were harvested at the times (0h, resting-Sample 1 and 2; 6h, activated-Sample 3 and 4) and analyzed by microarray.
Project description:CD4+ T cells (T helper cells) are cytokine-producing adaptive immune cells that activate or regulate the responses of different immune cells. They are known to play crucial roles in antibody class switching in B cells, neutrophil recruitment and activation of macrophages and CD8+ cytotoxic T cells. The activation and functional status of CD4+ T cells is important for adequate responses to pathogen infections but has also been associated with auto-immune disorders and survival in several cancers. In the current study, we carried out proteomic profiling of resting and activated primary human CD4+ T cells from healthy donors. In addition to identifying known markers of CD4+ T cell activation, we also identified protein kinases, protein phosphatases, and cytokines to be differentially expressed.
Project description:NGS-based assesement of miRNA expression and post-transcriptional modification kinetics in human primary resting and activated natural killer (NK) cells and their released small EVs
Project description:Resting NK cells are notoriously difficult to transduce, especially using the VSVG lentivirus pseudotype. When NK cells are expanded and activated using the NKAES system, there is a modest improvement of transduction rates compared to their resting NK counterparts. Still, the transduction efficiency remains poor for robust development of NK cell-based cancer immunotherapy. We envisaged to have a genome-wide expression profile of resting and activated NK (NKAES) cells in order to improve currrent transduction protocols .
Project description:We used a knock-in (KI) mouse expressing SLP-76 with a C-terminal One-Strep-Tag (OST). Such a system allowed the replacement in the genome of SLP-76 by its tagged version and its expression in physiological amounts. Then, by combining high affinity purification and label-free quantitative proteomics, we report here the first description of the SLP76 interactome in resting and activated primary cultured mast cells derived from mice expressing an OST at the C-terminus of SLP-76 (Slp76OST/OST mice).
