Project description:The ability of Lactiplantibacillus plantarum LOC1 and LOC3, originally isolated from fresh tea leaves, to modulate the response of murine macrophages to the activation of Toll-like receptor 4 (TLR4) by the stimulation with lipopolysaccharide (LPS) was evaluated.
Project description:Comparison of gene expression in wildtype and MyD88-/- C57BL/6J mouse macrophages treated with 10 ng/mL LPS for 2 hours versus media treated control macrophages, and, wildtype and MyD88-/- C57BL/6J mouse macrophages treated with live E. coli bacteria (log phase; 1 bact per 1 macrophage) for 2 hours versus media treated control macrophages. Cells from 4 mice of each geneotype were used and each individual provided its own control. Hybridizations of treated and control samples from each mouse were dye swap replicated. Wildtype macrophages treated with LPS vs control (GSM22617-GSM22623,GSM22625), MyD88-/- macrophages treated with LPS vs control (GSM22626-GSM22632), wldtype macrophages treated with E. coli vs control (GSM22633-GSM22640, and MyD88-/- macrophages treated with E. coli vs control (GSM22641-GSM22648).

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:Hypericum perforatum extracts have been used as dietary supplements to treat conditions including mild-moderate depression and inflammation. A group of four bioactive constituents were identified from an active fraction of the extract. In order to identify the mechanism for the potential anti-inflammatory activity of the identified compounds, we used Affymatrix microarray to study the gene expression profile impacteded by these compounds, as well as the active fraction in LPS-stimulated mouse macrophages. We treated RAW264.7 mouse macrophages with DMSO control, active fraction from Hypericum perforaum extract, and a combination of the 4 putative bioactive compounds, called the 4-component system, all with and without LPS induction. A total of six treatment combinations were included in the final gene expression analysis using microarray.
Project description:Immunoresponsive gene 1 (IRG1) is one of the highest induced genes in macrophages under pro-inflammatory conditions and its function has been recently described: it codes for immune-responsive gene 1 protein/cis-aconitic acid decarboxylase (IRG1/CAD), an enzyme catalyzing the production of itaconic acid from cis-aconitic acid, a tricarboxylic acid (TCA) cycle intermediate. Itaconic acid possesses specific antimicrobial properties inhibiting isocitrate lyase, the first enzyme of the glyoxylate shunt, an anaplerotic pathway that bypasses the TCA cycle and enables bacteria to survive on limited carbon conditions. To elucidate the mechanisms underlying itaconic acid production through IRG1 induction in macrophages, we examined the transcriptional regulation of IRG1. Using a combination of literature information, transcription factor prediction models and genome-wide expression arrays, we inferred the regulatory network of IRG1 in mouse and human macrophages. 3 unstimulated (Control) and 3 LPS-stimulated RAW 264.7 macrophages
