Expression data from healthy human PB B cell subsets

ABSTRACT: Human PB B cell subsets are functionally distinct and may derive from different developmental pathways, reflected by their differential gene expression profiles. We used microarrays to detail the global programme of gene expression underlying germinal center transition and functional propensities of individual subsets according to surface receptor and cell adhesion molecule expression.

Expression data from healthy human PB B cell subsets

Project description:Human PB B cell subsets are functionally distinct and may derive from different developmental pathways, reflected by their differential gene expression profiles. We used microarrays to detail the global programme of gene expression underlying germinal center transition and functional propensities of individual subsets according to surface receptor and cell adhesion molecule expression. Human PB B cell subsets were sort-purified, RNA was extracted and processed. Data were vsn-normalized, corrected for batch-effects (ComBat) and analysed with GeneSpring GX7.

Genome-wide analysis of chromatin accessibility in human tonsillar B cell subsets

Project description:We performed ATAC-Seq on three freshly dissociated human tonsils sorted to purity into the following B-cell subsets: CD19+ naïve (IgD+/CD38-), memory (IgD-/CD38-), germinal center light zone (IgD-/CD38mid/CD83+/CXCR4lo), germinal center dark zone (IgD-/CD38mid/CD83lo/CXCR4hi), and plasma cells (IgD-/CD38hi). We used these data to derive differentially accessible sites between B-cell subsets and relative to EBV-immortalized B cell lines (LCLs). These studies revealed similarities between LCLs and both DZ and LZ GC cells at the BCL2A1 (BFL1) locus that formed the impetus for further three-dimensional chromatin studies, which are the focus of the associated manuscript.

Transcriptome of subsets of human haematopoietic stem cells from non-mobilised peripheral blood of healthy donors

Project description:Integration of index sorting and single cell functional assays identified two functionally distinct subsets of phenotypic haematopoietic stem cells and multipotent progenitors (HSC/MPPs) in the peripheral blood (PB) from healthy individuals. CD71- HSC/MPPs from PB are multipotent and can repopulate the NSG xenograft model. CD71+ HSC/MPPs are a subset of phenotypic HSC/MPPs that is uniquely restricted to give rise to erythroid and megakaryocytic lineages, and expands in conditions with chronic stimulation of platelet production (e.g. frequent platelet donation, idiopathic thrombocytopenic purpura, essential thrombocythaemia). Here, we report the bulk transcriptomes of pools of 20 cells from CD71- HSC/MPPs (CD19- CD38- CD45RA- CD34lo CD71-) and CD71+ HSC/MPPs (CD19- CD38- CD45RA- CD34lo CD71+). Altogether the data shows the transcriptional similarities and differences between both subsets. It shows, that the unique erythroid/megakaryocytic lineage-priming of CD71+ HSC/MPPs is already initiated at transcriptional level, and that CD71+ HSC/MPPs differ from CD71- HSC/MPPs with regards to their protein synthesis/metabolic pathways.

miRNA profiles of tonsillar B cell subsets

Project description:In order to assess the miRNA signature of B cells undergoing the germinal center reaction, we isolated three subsets of B cells from tonsils--naive (N), germinal center (GC), and memory (M) and looked at their miRNA profile. We looked at three subsets of B cells, isolated from tonsils obtained from four different donors. Thus, we profiled a total of 12 samples, and each tonsillar subset--N, GC, and M, had four biological replicates.

scRNA-seq analysis of murine MBC subsets

Project description:Purpose: We wanted to explore further heterogeneity of MBC subsets that were previously defined by our lab. Methods: MBC subsets were sorted and stained with unique anti-mouse HTO antibodies (CITE-seq). Results: We found that heterogeneity among MBC subsets was most prominent among DP MBC subsets, which could be separated by extrafollicular or germinal center transcriptional signatures, whereas DN and SP MBCs mostly exhibited an extrafollicular signature.

Comprehensive protein-expression map of ILC2 and ILC3 subsets in healthy human skin

Project description:Innate lymphoid cells (ILCs) have emerged as essential players in the skin-associated immune system in health and inflammatory skin diseases. Their low numbers and lack of specific markers hampered extensive characterization and consequently resulted in limited knowledge of their protein expression. Here, we combined flow cytometry and state-of-the-art proteomics to comprehensively describe the proteins constitutively expressed by ILC2 and ILC3 subsets derived from healthy human skin and peripheral blood. We quantified 6666 proteins from skin ILC and identified 608 differentially expressed proteins in the investigated subsets. In addition to the current analyses, highlighting new functions of ILC, the ILC proteomic libraries and the proteomes of the ILC2 and ILC3 subsets will serve as valuable resources for future analyses of ILC function and are available at http://skin.science.

Autofluorescence positive and negative microglia constitute novel subsets found in healthy brain.

Project description:Utilizing autofluorescence (AF) as a discriminating parameter, we identified two novel microglia subsets in both mice, termed autofluorescence-positive (AF+) and negative (AF-), and characterized them by label-free proteomics.
