Project description:Monocyte differentiate into macrophages that display either pro-inflammatory or tolerogenic profile depending on the inflammatory condition of the intestine. We performed adoptive monocyte transfer to dissect the dynamics of monocyte to macropahges differentiation. Gene expression analysis of donor monocyte-derived cells recovered from non-inflamed and inflamed small intestine of recipient mice at day 1, 2 and 5 after transfer for in-depth investigation of monocyte development in the intestine.
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. Keywords: agent response
Project description:In vitro experiment of stimulation of monocyte-derived dendritic cells with Saccaromyces cerevisiae in exponential growth phase. This experiment was performed to verify the comparability of microarray experiments using a pathway based logic (Beltrame et al., PLoS 2009) by comparing the analysis of this sample with other seven public data sets on monocyte-derived dendritic cells subjected to different stimuli retrieved from GEO Keywords: Case-control, transcriptional profiling, dendritic cells A case-control experiment consisting of 3 case samples (stimulated dendritic cells) compared to 3 paired (from the same donor) samples
Project description:To examine the miRNA changes that occur during macrophage and dendritic cell differentiation we used the miRCURY LNATM microRNA Array (7th Gen) to profile monocyte-derived macrophages and monocyte-derived dendritic cells. Of the 2046 probes present on the assay, we detected expression of ~400 (20%) miRNAs across all samples.

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.
Project description:Human monocyte-derived DC were cultured at a density of 0.5x10E6 cells/ml in RPMI-1640 supplemented with 10% FCS, 1% Pen/Strep, 10 ng/ml GM-CSF and 10 ng/ml IL4. At day 7, they were stimulated or not with 500 ng/ml LPS. Cells were collected at day 10.
Whole cell lystaes from 2x10E8 cells were used for immunoprecipiation with PU.1 (T-21 SantaCruz) antibody. IgG was used as control.
