Project description:RNA sequencing was used to characterize PGE2-mediated changes in the gene expression profile of human conventional type 1 dendritic cells (cDC1) purified from PBMCs of healthy donors. Our analysis shows that treatment of cDC1 with PGE2 induces transcriptional changes in resting cDC1. cDC1 activated with a TLR3 ligand after PGE2 pre-treatment show alterations in the expression of activation induced genes.
Project description:RNA sequencing was used to characterize PGE2-mediated changes in the gene expression profile of conventional type 1 dendritic cells (cDC1). Our analysis shows that treatment of cDC1 with PGE2 or conditioned medium from PGE2-producing tumors induces transcriptional changes in resting cDC1. cDC1 activated with a TLR3 ligand after PGE2 pre-treatment show alterations in the expression of activation induced genes.
Project description:RNA sequencing was used to characterize in situ tumor infiltrating conventional type 1 dendritic cells (cDC1) in BRAFV600E melanoma tumors transplanted into C57BL/6 wildtype mice. Our analysis shows PGE2-dependent differences in the gene expression profile of intratumoral cDC1.
Project description:Purpose: Investigate the gene accessibility change of neutrophils from PGE2 stimulation and identify the posibility for PGE2 could induce lung neutrophil like characteristics. Methods: Isolated bone marrow neutrophils with Percoll gradient are treated with 10 μM of PGE2 for 24 hours. Conclusion: Chromatin accessibility for the genes that were upregulated in lung neutrophils and PGE2 treated neutrophils were increased, so PGE2 could induce lung neutrophil like characteristics with change chromatin accessibility.
Project description:Purpose: Investigate the neutrophils could exspress different mRNA de novo from PGE2 stimulation. Methods: Isolated bone marrow neutrophils with Percoll gradient are treated with 10 μM of PGE2 for 24 hours. Results: Qualified sequence reads per sample to the mouse genome (mm10) with Bowtie2 or STAR were processed with StringTie and identified genes. Conclusion : 1,359 genes were significantly different in PGE2 treated bone marrow neutrophils from vehicle treated ones.
Project description:To investigate the effects of IL-1β/IL-6/PGE2 on neutrophil modulation, we performed RNA-seq to compare IL-1β/IL-6/PGE2-treated neutrophils to vehicle-treated neutrophils.
Project description:Macrophages are at the front line of the innate immune system and differentiate from monocytes after infiltrating the infected tissue. Metabolic pathways are central to macrophage biology. We studied transcriptional differences between Rapamycin treated in vitro activated macrophages and untreated peripheral blood derived in vitro actiavted macrophages. We used microarrays to detail the global programme of gene expression in Rapamycin treated adult blood derived M(IL-10) and M(IFN-γ) macrophages and untreated adult blood derived M(IL-10) and M(IFN-γ)macropahges
Project description:ATAC sequencing was used to determine the impact of PGE2 signaling on NK cell function. Our analysis revealed that PGE2 induces a dysfunctional program in NK cells characterized by the inability to produce cytokines and chemokines upon their activation. Mechanistically, this program is governed by epigenetic changes downstream of the PGE2 receptors EP2 and EP4.
