Cellular Differentiation of Human Monocytes Is Regulated by Time-Dependent Interleukin-4 Signaling and the Transcriptional Regulator NCOR2.
Specimen part
View SamplesWhole transcriptome profiling (RNA-Seq) of a time kinetics experiment containing human monocyte-derived cells, which were activated with IL4 either directly at the start of the culture, or at different hours after an initial activation with GMCSF alone. Cells being activated solely with GMCSF were added as controls Overall design: CD14+ monocytes were FACS-sorted from blood of human healthy donors and later activated in vitro with either GMCSF alone for 72 hours to obtain Mo-GMCSF[IL4 (0h)] cells as controls, with the combination of GMCSF and IL4 for 72 hours or 144 hours to obtain Mo-GMCSF[IL4 (0-72h)] or Mo-GMCSF[IL4 (0-144h)] cells, respectively, or with first GMCSF and then with the combination of GMCSF and IL4 for different durations. For the latter, monocytes were first activated with GMCSF for either 12, 24, 48 or 72 hours, and then with GMCSF plus IL4 until a total activation time of 144 hours. This resulted in Mo-GMCSF[IL4 (12-144h)], Mo-GMCSF[IL4 (24-144h)] , Mo-GMCSF[IL4 (48-144h)] and Mo-GMCSF[IL4 (72-144h)] cells, respectively.

View SamplesWhole transcriptome profiling (RNA-Seq) was performed on human Mo-GMCSF[IL4 (0-72h)] cells with either NCOR2 being knocked down or corresponding WT cells Overall design: CD14+ monocytes were FACS-sorted from blood of human healthy donors and later activated in vitro with the combination of GMCSF and IL4 for 72h to obtain Mo-GMCSF[IL4 (0-72h)] cells. During the last 24 hours of activation, either siRNAs targeting NCOR2 or scrambled RNAs were added to obtain NCOR2 knock down cells and corresponding WT cells, respectively

View SamplesHere we investigated whether sterile triggers of inflammation induce trained immunity and thereby influence innate immune responses. Western diet (WD) feeding of Ldlr-/- mice induced systemic inflammation, which was undectable in serum soon after mice were shifted back to chow diet (CD). In contrast, myeloid cell responses towards innate stimuli remained broadly augmented. WD induced transcriptomic and epigenomic reprogramming of myeloid progenitor cells, leading to increased proliferation as well as enhanced innate immune and interferon responses towards in vivo LPS challenge. QTL analysis in human monocytes trained with oxidized low-density lipoprotein (oxLDL) and stimulated with LPS suggested inflammasome-mediated trained immunity. Consistently, Nlrp3-/-/Ldlr-/--deficient mice lacked WD-induced systemic inflammation or myeloid progenitor proliferation and reprogramming. Hence, NLRP3 mediates trained immunity following WD and could thereby arbitrate the potentially deleterious effects of trained immunity in inflammatory diseases. Overall design: Examination of GMPs in six different conditions by RNA-seq

View SamplesOxidative stress is a harmful condition in a cell, tissue, or organ, caused by an imbalnace between reactive oxygen species and other oxidants and the capacity of antioxidant defense systems to remove them. The budding yeast S. cerevisiae has been the major eukaryotic model for studies of response to oxidative stress.

View SamplesCortical development is a complex process involving the generation of neuronal progenitors, which proliferate and migrate to form the stratified layers of the maturing cortex. To identify microRNAs (miRNAs) and genes that may be important during early cortical development, we analyzed the expression profiles of rat neuronal progenitors obtained at embryonic day 11 (E11), E12 and E13 using microarrays. Neuronal progenitors were purified from telencephalic dissociates with a positive-selection strategy using surface labeling tetanus-toxin and cholera-toxin and fluorescence-activated cell sorting. We identified classes of miRNAs and mRNAs that were up-regulated or down-regulated in these neuronal progenitors as cortical development progressed from E11 to E13. We present data that supports a regulatory role for miRNAs during the transition from neuronal progenitors into differentiating cortical neurons.
