Project description:The effect of PDGF-DD on the gene expression of human tonsil ILC1 is unknown. We used microarray to determine the transcriptional differences between unstimulated and PDGF-DD-stimulated human tonsil ILC1.
Project description:To investigate miRNA expression in human tonsil squamous cell carcinoma (SCC) compared to normal tonsil tissue. Two colour LNA Exiqon array. MicroRNAs were labeled at 3'-end with a P-CU-C3-Cy3 RNA linker. A mixture of 371 synthetic DNA reference oligonucleotides containing complementary sequences to all LNA probes was randomly labeled using the ULYSIS labeling kit.
Project description:B cells from human tonsil and blood were sorted using flow cytometry. The human samples were processed immediately ex-vivo using markers for known B cell subsets.
Project description:Innate lymphoid cell (ILC) subsets that mirror helper T cells in their effector cytokine profiles have recently emerged as central players in both homeostatic and inflammatory conditions. Like their Th1, Th2 and Th17/Th22 helper T cell counterparts, ILC subsets are categorized based on their expression of specific transcription factors and effector cytokines: group 1 ILC (ILC1) express T-bet and IFN-γ; group 2 ILC (ILC2) express GATA-3 and type 2 effector cytokines such as IL-13 and IL-5; and group 3 ILC (ILC3) express RORgt and the cytokines IL-22 and/or IL-17. Under this nomenclature, natural killer (NK) cells and lymphoid tissue inducers (LTi) are considered ILC1 and ILC3, respectively. ILC1 contain both CD4+ and CD4- populations, but whether this phenotypic characteristic reflects functional differences between these two populations is unknown. These studies examine the gene expression profiles of CD4+ vs CD4- ILC1 in a cohort of healthy control subjects. ILC subsets were isolated from the peripheral blood of healthy control subjects. cDNA was isolated and amplified from sorted populations, and gene expression was analyzed by RNAseq
Project description:Transcriptional profiling of human glioma cells comparing control GFP expressing cells with glioma cells transfected with a human PDGF-A gene. The isogenic cell lines were used to study the impact on glioma tumorigenesis and invasion. Goal was to determine the effects of PDGF-A gene transfection on global ES gene expression. Two set of glioma cell lines, LN444 vs LN444/PDGF-A and LN443 vs LN443/PDGF-A. Biological replicates: 2 control replicates, 2 transfected replicates.
Project description:Single cell RNA-sequencing of human tonsil Innate lymphoid cells (ILCs) from three independent tonsil donors. Sequencing libraries were prepared from FACS sorted individual ILCs with the Smart-Seq2 protocol (Picelli et al. Nature Methods 2013)
Project description:Transcriptional profiling of human glioma cells comparing control GFP expressing cells with glioma cells transfected with a human PDGF-A gene. The isogenic cell lines were used to study the impact on glioma tumorigenesis and invasion. Goal was to determine the effects of PDGF-A gene transfection on global ES gene expression.
Project description:This project studies the differential abundance of proteins at excitatory synapses of PDGF-hSyn mice (Masliah et al., 2000, Science), which are a model for Parkinson’s disease/dementia with Lewy bodies. The mice overexpress human alpha synuclein under the human PDGF promoter. Synapses were purified from animals expressing fluorescently tagged vGlut1 (vGlut1-Venus) using fluorescence activated synapse sorting (FASS; cf. Biesemann et al., 2014, EMBO J).
