Project description:We aimed to investigate the effect of PTX3 on macrophages functions. After PTX3 stimulation for 18 h in THP-1 macrophages, total RNA were harvested for RNA-seq analysis of ctrl (n = 1) and PTX3 group (n = 1).

Project description:PTX3, as the long member of the pentraxin family, is produced mainly by dendritic cells, macrophages, and endothelial cells in response to inflammation. Growing amount of studies suggest that PTX3 can exert potential contradictory roles in inflammation regulation, antimicrobial resistance, and disease pathogenesis, depending on the tissue context, cellular source, and levels of production. To characterize the potential involvement of PTX3 in macrophage function, transcriptome sequencing (RNA-seq) was performed in human THP1-derived macrophages with PTX3 depletion. Notably,genes enrichment in PI3K/AKT signaling , JAK/STAT signaling and autophagy pathway were observed in PTX3 deficiency macrophages. This study highlights the critical roles of PTX3 on regulation macrophages homeostasis.

Project description:The effect of SAA1 treatment on global gene expression in THP-1 macrophages was studied. The study determined the gene expression upon wild-type SAA1 treatment, variant SAA1 treatment (p.Gly72Asp) and in untreated THP-1 macrophages. SAA1 treatment of macrophages induces the expression of genes involved in inflammation, angiogenesis, phagocytosis and tissue remodeling which are important in the pathogenesis of chronic inflammatory diseases such as atherosclerosis and rheumatoid arthritis. THP-1 macrophages were treated with SAA1 for either 8 hours or 24 hours. RNA were then extracted and the gene expression pattern was compared between (i) wild-type SAA1 vs untreated (ii) variant SAA1 vs wild-type SAA1 at both 8 hr and 24 hr.

Project description:By identifying differentially expressed LncRNAs/mRNAs in THP-1 macrophages and THP-1 macrophage-derived foam cells, we select some differentially expressed LncRNAs and explore their roles in atherosclerosis process. We already find that some LncRNA can effect cholesterol metabolism and level of inflammation factor, which may influence atherosclerosis process.

Project description:Inflammasome activation in macrophages induces the release of EVs, however, the effect of these inflammasome-induced EVs on recipient cells is poorly characterized. To characterize the effect EVs released upon LPS + nigericin stimulation, we performed 3' sequencing on the recipient cells (NLRP3 KO THP-1 macrophages and NLRP3 KO THP-1 macrophages that have been reconstituted with NLRP3 to resemble the WT). As controls, RNA isolated from EVs themselves or LPS- or nigericin-treated cells were subjected to 3' sequencing.

Project description:Background: Macrophages represent an important part of the immune system in the intestine and are crucial for maintaining homeostasis. As part of research investigating the effect of dietary fibres on the intestinal immune barrier THP-1 macrophages were used as model system. Methods: THP-1 monocytes were stimulated for 48 hours with 100 ng/ml PMA and 48 hours rested in medium. Subsequently, they were stimulated with 500 ug/ml dietary fibres and the maximal observed LPS contamination to serve as background control. After 6 hours, total RNA was extracted and Affymterix Human Gene 1.1 ST arrays were used to analyze the gene expression profiles. To identify dietary fibre induced gene expression profiles in dietary fibre gene responses were compared to medium samples. Furthermore, to analyse differentiatlly affected pathways Ingenuite Pathway Analysis was employed. Results: There was a clear difference in significantly differentially expressed genes (gene cut-off p<0.05) with beta-glucan oat medium viscosity and GOS changing transcription of a relative small amount of genes and Sugar beet pectin and Resistant starch a relative large amount of genes. These latter two were also the only dietary fibres to demonstrate an increase in Fc-receptor-related pathway activation. Alternatively, beta-glucan oat medium viscosity and GOS were the only dietary fibres to activate pathways related to cellular movement and the only two to not activate the Ahr-signaling pathway (p<0.05). Conclusion: our data indicate that the in vitro THP-1 macrophage model can be used to differentiate in immunomodulatory potential of dietary fibres and provide hypotheses for functional differentiation.
