| Title |
L+a-T [Donor127_9] |
| Sample type |
RNA |
| |
|
| Source name |
monocyte derived dendritic cells
|
| Organism |
Homo sapiens |
| Characteristics |
condition: L+a-T
tissue: blood
time point: H8
|
| Treatment protocol |
Monocyte-derived DCs were pre- treated for one hour with mouse IgG1 (20 µg/mL, R&D Systems), mouse anti-IL10R blocking antibody (10 µg/mL, R&D Systems) or mouse anti-TNFα Receptors 1 and 2 (10 µg/mL, R&D Systems) and then cultured with medium or LPS (100 ng/mL, LPS-EB Ultrapure, activates TLR4 only, Invivogen) for additional 4 or 8 hours based on the time point
|
| Growth protocol |
Fresh blood samples collected from healthy donors were obtained from Hôpital Crozatier Établissement Français du Sang (EFS), Paris, France, in conformity with Institut Curie ethical guidelines. PBMCs were isolated by centrifugation on a Ficoll gradient (Ficoll-Paque PLUS, GE Healthcare Life Sciences). Monocytes were selected using antibody-coated magnetic beads and magnetic columns according to manufacturer’s instructions (CD14 MicroBeads, Miltenyi Biotec). To generate immature DCs, CD14+ cells were cultured for 5 days with IL-4 (50 ng/mL) and GM-CSF (10 ng/mL) in RPMI 1640 Medium, GlutaMAX (Life Technologies) with 10% FCS.

| Description |
gene expression data for MoDC stimulated 8 hours with LPS + anti-TNFR blocking antibodies
|
| Data processing |
Expression data were normalized with Plier. Transcriptomics analysis was performed in a Matlab environment. For independent filtering, we used the function geneverfilter, which calculates the variance of each probe across the samples and identifies the ones with low variance. Probes with variance less the 40th percentile were filtered out because poorly informative.
