Project description:HOIL-1 deficient disease is a new early onset fatal autosomal recessive human disorder charaterized by chronic auto-inflammation, recurrent invasive bacterial infections and progressive muscular amylopectinosis. We studied the effect of TNF-α and IL-1β on transcriptional changes of primary fibroblasts from HOIL-1-, MYD88- and NEMO-deficient patients. Primary fibroblasts were obtained from HOIL-1, MYD88- and NEMO-deficient patients and healthy donors and stimulated with TNF-α or IL-1β for 2 and 6 hours. RNA were extracted and globin reduced. Labeled cRNA were hybridized to Illumina Human HT-12 Beadchips.

Project description:This experiment aims to identify the biological pathways and diseases associated with the cytokine Interleukin 13 (IL-13) using gene expression measured in peripheral blood mononuclear cells (PBMCs). The experiment comprised of samples obtained from 3 healthy donors. The expression profiles of in vitro IL-13 stimulation were generated using RNA-seq technology for 3 PBMC samples at 24 hours. The transcriptional profiles of PBMCs without IL-13 stimulation were also generated to be used as controls. An IL-13R-alpha antagonist (Redpath et al. Biochemical Journal, 2013) was introduced into IL-13 stimulated PBMCs and the gene expression levels after 24h were profiled to examine the neutralization of IL-13 signaling by the antagonist.
Project description:With this experiment, we aimed at showing changes in the proteome and secretome of porcine peripheral blood mononuclear cells (PBMC) after stimulation with Banana Lectin (BanLec).
Project description:We developed a humanized mouse model of graft-versus-host disease in which Treg injected two days after PBMC persist in the blood of infused mice and can be characterized. This model provides in vivo assessment of manipulated Treg. We used that model to evaluate the impact of ex vivo priming of Treg with TNF-alpha on their ability to prevent xenogeneic GVHD. Indeed, it had been demonstrated that Treg function can be enhanced through stimulation of TNFR2. scRNAseq analysis was performed to assess the impact of TNF priming on Treg transcriptomics. Peripheral blood mononuclear cells were isolated from the blood of three healthy donors. Treg were isolated through immuno-magnetic selection then cultured for 24 hours with IL-2 at 10 ng/mL with or without TNF at 100 ng/mL. After 24 hours, cells were collected and washed. We performed cell multiplexing to label samples individually, then pooled them for single cell RNA sequencing. For each donor (named donors 3, 4 and 7), half cells were in the control group (no TNF) and half cells were in the experimental group (with TNF). 10x Genomics 3’ Single Cell Gene Expression with CellPlex multiplexing (Set A). Cells were labeled with Cell Multiplexing Oligos prior to pooling and library preparation.
Project description:Purpose: We analyzed RNA-seq from peripheral blood mononuclear cells (PBMC) in DMARDs-naïve RA patients and healthy subjects. Our goal was to evaluate the transcriptional profiles of ST2825-treated PBMC to identify its therapeutic potential. Methods: We analyzed bulk RNA-seq from peripheral blood mononuclear cells (PBMC) in DMARDs-naïve RA patients after stimulation with LPS and IL-1β, PBMC were treated with the MyD88 chemical inhibitor, ST2825. Collection of RNA was performed after 24 h of treatment and samples were sequenced to determine transcriptional changes and regulated processes in treated PBMC. Results: paired-end reads were mapped to the hg19 human genome assembly. RNA levels were normalized using DESeq. We identified 796 differentially expressed (DE) genes by 2-fold change (p<0.05) between RA patients and healthy subjects. Our analysis revealed 631 DE genes between DMARDs-naïve RA patients before and after ST2825 treatment. We identified 471 DE genes between LPS-stimulated RA PBMC and LPS-stimulated RA PBMC treated with ST2825. Conclusion: Our study provides comprehensive evidence supporting the potential application of the MyD88 inhibitor, ST2825, as a modulator of gene expression signtaures involved in pathogenic processes in PBMC from DMARDs-naïve RA patients. Our indepth analysis of RNA-seq data will serve as a valuable resource containing the inflammatory gene expression signatures by MyD88.
