Gene expression profile at single cell level of periheral blood mono-nucleus cells (PBMC) in response to bacterial protein (PFOR) stimulation

ABSTRACT: We identified Pyruvate:Ferredoxin Oxidoreductase (PFOR) as a bioactive protein from Faecalibacterium prausnitzii. We usd single cell transcriptome sequencing to fully evaluate the PFOR's effect on PBMC.

Faecalibacterium prausnitzii abrogates immunotherapy toxicity

Project description:To elucidate whether Faecalibacterium prausnitzii has effects on intestinal toxicity induced by immune checkpoint inhibitors, we performed RNA-seq analysis of colon tissues of mice receiving DSS, DSS+ICB and DSS+ICB+F. prausnitzii gavage to compare the gene expression profiles.

RNAseq of Faecalibacterium prausnitzii A2-165 stimulated with cell-free supernatants from lactic acid bacteria.

Project description:We explored the transcriptional response of Faecalibacterium prausnitzii A2-165 when exposed to cell-free supernatants from different Lactobacillus, Streptococcus and Lactococcus strains. For that, we sequenced its RNA and looked for significant differences in the expression levels among the supernatants groups.

Anti-inflammatory Effects of the Commensal Bacterium Faecalibacterium prausnitzii analyzed by microarrays

Project description:The human intestinal microbiota plays an essential role in host health. Modifications in its composition and diversity could induce pathologies such as inflammatory bowel diseases (IBD). These diseases are characterized by an unbalanced intestinal microbiota (a process known as dysbiosis) and an altered immune response. Faecalibacterium prausnitzii, the most abundant commensal bacterium in the human intestinal microbiota of healthy individuals (representing more than 5% of the total bacterial population), has been reported to be lower in feces and mucosa-associated microbiota of IBD patients. In addition, we have shown that both F. prausnitzii and its culture supernatant (SN) have anti-inflammatory and protective effects in both acute and chronic colitis models. However, the host molecular mechanisms involved in these anti-inflammatory effects remain unknown. In order to address this issue, we performed DNA chip-based transcriptomic analyses in HT-29 human intestinal epithelial cells stimulated with TNF-a and exposed to F. prausnitzii SN or to BHI (growth medium for F prausnitzii).

An integrative multi-omics approach to characterize prebiotic inulin effects on Faecalibacterium prausnitzii

Project description:Faecalibacterium prausnitzii, a major commensal bacterium in the human gut, is well known for its anti-inflammatory effects, which improve host intestinal health. Although several studies have reported that inulin, a well-known prebiotic, increases the abundance of F. prausnitzii in the intestine, the mechanism underlying this effect remains unclear. In this study, we applied liquid chromatography tandem mass spectrometry (LC-MS/MS)-based multi-omics approaches to identify biological and enzymatic mechanisms of F. prausnitzii involved in the selective digestion of inulin. An LC-MS/MS-based intracellular proteomic and metabolic profiling was performed to determine the quantitative changes in specific proteins and metabolites of F. prausnitzii when grown on inulin. Interestingly, proteomic analysis revealed that the putative proteins involved in inulin-type fructan utilization by F. prausnitzii, particularly b-fructosidase and amylosucrase were upregulated in the presence of inulin. To investigate the function of these proteins, we overexpressed bfrA and ams, genes encoding beta-fructosidase and amylosucrase, respectively, in Escherichia coli, and observed their ability to degrade fructan. In addition, the enzyme activity assay demonstrated that intracellular fructan hydrolases degrade the inulin-type fructans taken up by fructan ATP-binding cassette transporters. Furthermore, we showed that the fructose uptake activity of F. prausnitzii was enhanced by the fructose phosphotransferase system transporter when inulin was used as a carbon source.
