Project description:We aimed to characterize CD11c+ B cells from healthy humans by gene expression analysis. We report that CD11c+ B cells are a distinct subpopulation of B cells, even if their phenotype is heterogeneous, with overexpression of genes involved in B cell activation and antigen presentation.
Project description:To characterize human bone marrow plasma cells that express or lack CD19 on a molecular level, we compared the global gene expression of primary CD38high/CD138+ plasma cells with or without CD19 expression.
Project description:The goal of our study is to determine whether Atg16L1 deficiency leads to differences in the transcriptional profile of CD11c+ Dendritic Cells, ultimately leading to an increased inflammatory phenotype. CD11c+ cell sorted splenic DCs were isolated from 8 week old WT and Atg16L1 hypomorphic mice from spleens of untreated mice and were placed directly into TRIzol LS (Invitrogen). mRNA was isolated, amplified, and hybridized to an Affymetrix GeneChip (MOE430A).

Project description:We used DNA microarray technology to assess changes in gene expression after treatment of 11 lymphoma cell lines with epigenetic drugs. We identified genes with upregulated expression in treated cell lines and with downregulated expression in B-cell lymphoma patient samples when compared to normal B cells. CD19+ b cells were isolated from buffy coats from diffrent healthy donors. Gene expression of healthy controls (CD19+ b cells) was used as a normal counterpart for lymphoma samples (GSE4732, GSE10846).
Project description:In this study gene expression of CD1c+ CD19- blood dendritic cells from healthy subjects were investigated. Keywords: expression profiling by array Blood DCs (CD1c+ CD19-) were isolated from venous heparinized blood of three apparently healthy human volunteers using the CD1c+ (BDCA-1) dendritic cell isolation kit from Miltenyi according to the manufacturer’s instructions. Purity over 90% (95.8±3%) was determined by FACS analysis. RNA was isolated and 1 µg was labeled using the Affymetrix One-Cycle Target Labeling Kit and the biotinylated cRNA used to perform Affymetrix U133 Plus 2.0 expression arrays.
Project description:Purpose: To compare cell states between CD19-28z and GD2-28z human CAR T cells on day 10 of cell culture. Methods: Human T cells were activated and lentivirally transduced with CD19-28z or GD2-28z CAR constructs and maintained in culture for 10 days, and then delivered to the Stanford Functional Genomics Facility for 3' single-cell RNA-sequencing on the 10X Genomics platform. Results: Comparison of transcription factor profiles by single cell RNA-seq analysis of CD8+ T cells expressing CD19-28z vs. GD2-28z CAR confirmed that the bZIP family members JUN, JUNB, JUND, and ATF4 were among the most differentially expressed and broadly connected in exhausted GD2-28z CAR T cells. Conclusions: This study provides insights into cell states that could explain the underlying differences between highly functional CD19-28z CAR T cells and exhaustion-prone GD2-28z CAR T cells on day 10 in culture.
