Primary human blood-derived macrophages (BDMs): control vs. infected

ABSTRACT: Transcriptional profiling of primary human blood-derived macrophages (BDMs) comparing control untreated BDMs with BDMs exposed with Streptococcus pneumoniae strain D39 (MOI 0.1 and 0.5) for 16 hours) Two-condition experiment, control BDMs vs. infected BDMs. Biological replicates: 3 control replicates, 3 infected replicates MOI 0.1, 2 infected replicates MOI 0.5).

Streptococcus pneumoniae causes high mortality as a major pneumonia-inducing pathogen. In pneumonia, control of innate immunity is necessary to prevent organ damage. We assessed the role of microRNAs (miRNAs) as regulators in pneumococcal infection of human macrophages. Exposure of primary blood-derived human macrophages with pneumococci resulted in transcriptional changes in several gene clusters and a significant deregulation of 10 microRNAs. Computational network analysis retrieved miRNA-146a ...[more]

Human bronchial epithelial cell line Beas-2B

Project description:Human bronchial epithelial cell line Beas-2B were infected with Streptococcus pneumoniae at Multiplicity of Infection (MOI) of 0.5 and 1 or treated with lipoteichonic acid (LTA) for 9 and 16 h. The mRNA profile changes upon infection shall be determined to investigate Streptococci pathogenesis.

7de3a7c0-d84a-4338-94c1-6c32fdcee063 - samples

Project description:This dataset includes a total of 5 single cell RNA sequencing (scRNAseq) data of SARS-CoV-2 infected human alveolar stem cell culture models. Two scRNAseq data were obtained from SARS-CoV-2 infection with MOI of 1.0 (1 for control and 1 for infected case) and the other three were obtained from SARS-CoV-2 infection with MOI of 0.1 in the study entitled "Three-dimensional human alveolar stem cell culture models reveal infection response to SARS-CoV-2". The 10x Chromium Single Cell 3' Reagent kits were used to generate libraries.

Viral Effect on Metabolism (part II)

Project description:Small airway epithelial cell (SAEC) (Lonza Walkersville, Inc., MD) were grown according to the manufacturer's instructions in growth medium (SAGM) containing 0.03 mg/ml bovine pituitary extract (BPE), 0.5 µg/ml hydrocortisone, 0.5 ng/ml hEGF, 0.5 µg/ml epinephrine, 10 µg/ml transferrin, 5 µg/ml insulin, 0.1 ng/ml retinoic acid, 6.5ng/ml triiodothyronine, 50 µg/ml gentamicin and 50ng/ml Amphotericin-B, and 0.5 mg/ml bovine serum albumin (BSA, fatty acid free). When SAE grew to around 80 to 90% confluence, the cells were put into basal medium not supplemented with growth factors 3hours. Then the cell monolayers were infected with naïve hMPV at multiplicity of infection (MOI) of 3 to certain time. The supernatant was saved and cells were harvested and stored exactly according to the protocol provided by University of Michigan Metabolomics Core Facility for metabolomics analysis. 50mM ammonium acetate in water was used for rinse buffer.

RIPK3-dependent transcriptional program in flavivirus-infected neurons

Project description:Here, we characterize RIPK3-dependent transcriptional responses in cortical neurons following infection with neurotropic flaviviruses. Neurons were infected with either Zika virus (ZIKV) strain MR766 at an MOI of 0.1, West Nile virus (WNV) strain TX 2002-HC at an MOI of 0.001, or a saline mock solution. Neurons were derived from mice lacking RIPK3 expression (Ripk3-/-) or wildtype controls. These studies revealed a number of antiviral genes whose upregulation following viral infection is absent in neurons lacking RIPK3, a subset of which were validated using qRT-PCR.

Methylation data from biological replicates of imatinib and nilotinib resistant K-562 cells

Project description:Resistant cells were generated by stepwise exposure to increasing concentrations of imatinib or nilotinib to establish 0.5 and 2 µM imatinib and 0.1 µM nilotinib resistant cells. This procedure was performed twice independently to establish biological replicates of TKI resistance. We analyzed genome-wide methylation to investigate changes in methylation during the development of TKI resistance.

Comparative analysis using different multiplicity of infection ratios from Chlamydia-infected epithelial cells

Project description:Here we examined gene expression from an in-vitro dual-RNA-seq experiment using Chlamydia trachomatis-infected HEp-2 epithelial cells. The experimental design consisted of three different multiplicity of infection ratio's (0.1, 1 and 10) across two different timeframes (1 and 24hrs), in addition to applying two different depletion methods (rRNA and rRNA + PolyA depletion). The aim was to examine and outline which MOI and depletion methods are most suited for bacterial-based infections.
