10x single-cell RNAseq profiling of influenza Virus infected Human PBMCs treated with Dimethyl itaconate

Project description:Itaconic acid and its variant Dimethyl itaconate (DI) have shown an anti-inflammatory effect in different human cell lines and PBMCs during Infleunza A virus (IAV) infection. In this experiment, we further explored which cell types in PBMCs respond to IAV infection and DI treatment.

Global Protein Abundance and Phosphorylation Analyses of Influenza A Virus (IAV)-Infected Human Cells

Project description:Influenza A Virus (IAV) is a recurring respiratory virus with antiviral therapies of limited use. Understanding host proteins essential for IAV infection can identify targets for alternative host-directed therapies (HDTs). Using affinity purification-mass spectrometry and global phosphoproteomic and protein abundance analyses with three IAV strains (pH1N1, H3N2, H5N1) in three human cell types (A549, NHBE, THP-1), we mapped 332 IAV-human protein-protein interactions and identified 13 IAV-modulated kinases. Whole exome sequencing of patients who experienced severe influenza revealed several genes, including the structural scaffold protein AHNAK, with predicted loss-of-function variants that were also identified in our proteomic analyses. Of our identified host factors, 54 significantly altered IAV infection upon siRNA knockdown, and two factors, COPB1 and AHNAK, were also essential for productive infection by SARS-CoV-2. Finally, 16 compounds targeting our identified host factors suppressed IAV replication, with three targeting ATP6V1A, CDK2 and FLT3 showing pan-antiviral activity across influenza and coronavirus families. This study provides a comprehensive network model of IAV infection in human cells, identifying functional host targets for pan-viral HDT. This project includes the global proteomic data (abundance and phosphorylation), the AP-MS data has been submitted separately as its own dataset and has its own dataset identifier.

Transcriptional effects of exogenous lipid on differentiated THP-1 cells

Project description:Lipid laden macrophages (LLM) can often be found in the airway and may indicate aspiration secondary to gastro-oesophageal reflux (GOR). GOR is often associated chronic inflammatory airways diseases. We therefore sought to determine whether lipid droplets from undigested or partially digested food had an effect on macrophage gene expression leading to bronchial inflammation. To test this, we generated an in vitro model using differentiated THP-1 cells which were treated with a high fat liquid feed. Gene expression, using the Agilent G4851C (v3) array, in phorbol myristate acetate (PMA) differentiated THP-1 cells was compared to undifferentiated cells and lipid treated differentiated THP-1 cells.

Influenza viral RNA pulldown MS in THP-1 cells

Project description:Due to the RNA nature of their genomes, influenza viruses have to utilize many RNA-binding proteins (RBPs) of both viral and host origin, for their replication. To uncover the comprehensive vRNA-host protein interactions, we performed affinity purification coupled with mass spectrometry (AP-MS) analysis of influenza vRNA complexes. The eight vRNA segments of H7N9 were transcribed and individually labeled with biotin in vitro and incubated with IAV virus-infected THP-1 cells, and vRNA complexes were enriched streptavidin magnetic beads and analyzed by mass spectrometry

Itaconate links inhibition of succinate dehydrogenase with macrophage metabolic remodeling and regulation of inflammation

Project description:Remodeling of the tricarboxylic acid (TCA) cycle is a metabolic adaptation mechanism accompanying inflammatory macrophage activation. During this process, endogenous metabolites can adopt regulatory roles that govern specific aspects of inflammatory response, as recently shown for succinate, which regulates the downstream pro-inflammatory IL-1Î²-HIF1a axis. Itaconate is one of the most highly induced metabolites in activated macrophages, yet its functional significance remains unknown. Here, we show that itaconate modulates macrophage metabolism and effector functions via its effect on succinate dehydrogenase, by inhibiting conversion of succinate to fumarate. Through this action, itaconate exerts anti-inflammatory effects when administered in vitro and in vivo during macrophage activation and ischemia-reperfusion injury. Using newly generated Irg1-/- mice, which lack the ability to produce itaconate, we show that endogenous itaconate regulates succinate levels and function, changes in mitochondrial respiration, and inflammatory cytokine production during macrophage activation. These studies highlight itaconate as a major physiological regulator of the global metabolic rewiring and effector functions of inflammatory macrophages. Experiment 1: mature WT BMDM were treated for 12h with 0.25 mM dimethyl itaconate (DI) or vehicle (Unst) and then stimulated with LPS (E. coli 0111:B4; 100 ng/ml, 4h) (DI+LPS; LPS); Experiment 2: mature Irg1-/- BMDM were stimulated with LPS (E. coli 0111:B4; 100 ng/ml) and murine recombinant IFNg (50 ng/ml) for 24h.
