Project description:Monocyte exposure to lipopolysaccharide (LPS) induces a transient state in which these cells are refractory to further endotoxin stimulation. Here we demonstrate the transcriptome analysis of in vitro generated LPS refractory monocytes upon subsequent re-exposure to LPS for different time points. Total RNA obtained from human monocyte exposure treated with LPS for 3h, 6h, or 24h, subsequent to endotoxin tolerization or not.
Project description:Wild-type bone marrow-derived macrophages (BMDMs) were treated with vehicle (0.1% EtOH/D-PBS), 6h 100 ng/ml lipopolysaccharide (LPS) or 16h 1uM dexamethasone (Dex) and 6h 100 ng/ml LPS (Dex+LPS) and mRNA expression analysed by RNA-Seq.
Project description:Expression data of BL2 Burkitt Lymphoma cell line (controls and samples treated with different B cell specific stimuli) BL2 cells were cultured in RPMI and stimulated with the respective agents (rhCD40L, rhIL21, rhBAFF, LPS and antiIgM F(ab) fragments) for indicated timepoints. Cells were harvested and total RNA was isolated for gene expression profiling. The experiments were conducted in 2-3 biological replicates.
Project description:The hyperLOPIT proteomics platform combines mass-spectrometry with state-of-the-art machine learning for simultaneous “mapping” of the steady-state subcellular location of thousands of proteins. Here, we use a synergistic approach and combine global proteome analysis with hyperLOPIT in a fully Bayesian framework to elucidate the spatio-temporal changes that occur during the pro-inflammatory response to lipopolysaccharide in the human monocytic leukaemia cell-line THP-1. We report cell-wide protein relocalisations upon LPS stimulation.
