Expression data from mouse plasmacytoid dendritic cells stimulated with CpG and treated with lif

Project description:pDCs selectively express the receptor for leukemia inhibitory factor (LIF) that signals through STAT3. We performed microarray analysis of primary pDCs sorted from bone marrow of C57BL6 mice and incubated with a) medium; b) LIF; c) CpG; d) LIF plus CpG.

Transcription profiling of human plasmacytoid dendritic cells treated with p17 or CpG

Project description:We used microarrays to detail the global program of gene expression underlying the effect of p17 on human plasmacytoid dendritic cells and was compared to CpG profile. Experiment Overall Design: Human plasmacytoid dendritic cells were purified from two donors and cultured in the presence of p17 or CpG for 18 h.

Effect of IVIG on the activation of plasmacytoid dendritic cells

Project description:To investigate the effect of IVIG and desialylated IVIG on the activation of plasmacytoid dendritic cells (pDCs). Human primary plasmacytoid dendritic cells were treated with TLR stimulation together with or without IVIG or desialylated IVIG, and the change of genes were analyzed. Primary human pDCs were preincubated with or without 10mg/ml IVIG or desialylated IVIG followed by stimulation with CpG overnight. The different genes between IVIG+CpG and desialylated IVIG+CpG were analyzed.

RNA-seq of plasmacytoid dendritic cells stimulated by TLR3, TLR4, TLR7 and TLR8

Project description:Plasmacytoid dendritic cells (pDCs) are a rare type of dendritic cells that exist antiviral functions in response to toll-like receptors (TLRs). We here report TLR4 activated pDCs similar to TLR7/8 stimulation. Despite the high resemblance, we found the unique genes that were activated by TLR4 activation.

IRF-5 and IRF-8 govern the response of Human Plasmacytoid Dendritic Cells following TLR9 ligation

Project description:Synthetic oligonucleotides (ODNs) containing CpG motifs stimulate human plasmacytoid dendritic cells (pDCs) to produce type-1 interferons (IFN) and pro-inflammatory cytokines. Previous studies demonstrated that interferon regulatory factors (IRFs) played a central role in mediating CpG-induced pDC activation. This work explores the inverse effects of IRF-5 and IRF-8 on CpG dependent gene expression. Results from RNA interference and microarray studies indicate that IRF-5 up-regulates TLR9-driven gene expression whereas IRF-8 down-regulates the same genes. Several findings support the conclusion that IRF-8 inhibits TLR9 dependent gene expression by directly blocking the activity of IRF-5. First, the inhibitory activity of IRF-8 is only observed when IRF-5 is present. Second, proximity ligation analysis shows that IRF-8 and IRF-5 co-localize within the cytoplasm of resting human pDC and co-translocate to the nucleus after CpG stimulation. Taken together, these findings suggest that two transcription factors with opposing functions control TLR9 signaling in human pDCs. CAL-1 cells were transfected with siRNA targeting IRF-5 (IRF-5si) and left unstimulated (n=4, technical repeats) or stimulated with K-type CpG ODN (n=4, technical repeats). CAL-1 cells were transfected with siRNA targeting IRF-8 (IRF-8si) and left unstimulated (n=4, technical repeats) or stimulated with K-type CpG ODN (n=4, technical repeats). CAL-1 cells were transfected with control siRNA (Contsi) and left unstimulated (n=4, technical repeats) or stimulated with K-type CpG ODN (n=4, technical repeats).

Methylation data profiling for blastic plasmacytoid dendritic cell neoplasm

Project description:Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an aggressive malignancy assumed to originate from plasmacytoid dendritic cells (pDCs), which affects the skin and bone marrow and sequentially other organ systems. Here, we used EPIC arrays to characterize methylation profiles in 51 BPDCN cases.

Transcription profiling of human monocyte-derived dendritic cells after treatment with with CpG-oligo D19

Project description:Human monocyte-derived dendritic cell cultures devoid of contaminating plasmacytoid dendritic cells were treated with the D-type CpG-oligonucleotide D19, with the non-CpG-oligonucleotide control D, or were left untreated. Cells of all treatment groups stemmed from the same donor. 6 h after addition, cells were harvested, and total RNA was prepared for analysis of D19-dependent differential gene expression on Affymetrix HG-U 133A 2.0. Experiment Overall Design: One sample per treatment-group. No replicates.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN)_cases

Project description:Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy that is most similar in expression profiles to plasmacytoid dendritic cells. However, patients often exhibit features of AML and can progress to AML. In this project, we will determine the differentially and commonly expressed genes between BPDCN and AML specimens. Available BPDCN and TET2-mutated AML specimens were taken for transcriptome microarray analysis.
