Murine IgD+B Cells transcriptome analysis -untreated and when stimulated with LPS

ABSTRACT: Transcriptome comparison of untreated murine IgD+B cell with LPS treated IgD+B cell B-lymphocytes constitute an important aspect of mammalian immune systems by virtue of their ability to produce highly specific antibodies in response to foreign antigens and pathogens. When B-lymphocytes encounter the particular antigen that they are responsive to, they differentiate into two types of cells: short-lived antibody-secreting plasma cells and long-lived memory cells. While the plasma B cells are responsible for the rapid resolution of a current infection or immune challenge, the memory B cells are responsible for mounting a rapid response to subsequent exposures. Previous work had demonstrated that treatment of mice with a single dose of anti-CD40 at the time of immunization lead to improved secondary responses, suggesting an enhancement of the memory B cell pool. We are currently studying the molecular mechanisms underlying the generation of memory B cells, using CD40 signalling as a tool. We have carried out a Microarray analyses of genome wide gene expression patterns in naÃ¯ve B-lymphocytes following CD40 signalling, over multiple time points. Analysis used untreated IgD+B cells as control for comparison to LPS treated cells as test. Indirect comparisons were made across multiple arrays with raw data pulled from different channels for data analysis and comparison to the control data.

Murine IgD+ B cells transcriptome analysis when stimulated with LPS and LPS+anti-CD40 [24 hours]

Project description:B-lymphocytes constitute an important aspect of mammalian immune systems by virtue of their ability to produce highly specific antibodies in response to foreign antigens and pathogens. When B-lymphocytes encounter the particular antigen that they are responsive to, they differentiate into two types of cells: short-lived antibody-secreting plasma cells and long-lived memory cells. While the plasma B cells are responsible for the rapid resolution of a current infection or immune challenge, the memory B cells are responsible for mounting a rapid response to subsequent exposures. Previous work had demonstrated that treatment of mice with a single dose of anti-CD40 at the time of immunization leads to improved secondary responses, suggesting an enhancement of the memory B cell pool. We are currently studying the molecular mechanisms underlying the generation of memory B cells, using CD40 signalling as a tool. We have carried out a microarray analysis of genome-wide gene expression patterns in naÃ¯ve B-lymphocytes following CD40 signalling over multiple time points. The effect of LPS and LPS+antiCD40 on the transcriptome of IgD+ B cells was analyzed 24 hours after stimulation. The analysis used LPS-treated IgD+B cells as the control for comparison to LPS+anti-CD40-treated cells (test). Indirect comparisons were made across multiple arrays with raw data pulled from different channels for data analysis and comparison to the control data.

Single-cell RNAseq of phenotypically defined human B cell subsets

Project description:Separation of B cells has been historically important in discovering their functional relevance, particularly in relation to infection, immune disorders and vaccination. Traditional use of phenotypic markers often poses problems in distinguishing heterogeneous populations such as the Double Negative (DN, CD19+CD27-IgD-) cells. B cells represent a small subset of PBMCs; this represents challenges to use bottom-up approaches such as single-cell transcriptomics in defining B cell subpopulations. In this study we therefore used the 10X single-cell RNAseq platform on B cell populations already defined by FACS sorting (Transitional, CD19+CD27-IgD+CD10+; Naïve, CD19+CD27-IgD+CD10-; Classical Memory, CD19+CD27+IgD-; IgM Memory, CD19+CD27+IgD+; and DN). These data match known phenotypes to transcriptionally defined B cell subpopulations, and provide a reference atlas for researchers interested in better defining B cell subsets in their data.

ATAC-seq analysis of quiescent human splenic B cell populations

Project description:Memory B cells represent one of the pillar of humoral protection and are found in the circulation and secondary lymphoid organs several decades after initial pathogen or vaccine encounter. The exact cellular and biological mechanisms allowing long-term survival of quiescent cells in such a fluctuating microenvironment remain poorly understood. scRNA-seq analysis of long-lived Vaccinia-specific and total IgG+ memory B cells had helped us identify two subsets of quiescent switched memory B cells in the spleen of adult donors, separated by the expression of CR2(CD21). To better understand the relationship between these two resting splenic memory B cell subsets, we sorted CD21hiCD20hi and CD21intCD20int IgG+ memory B cells from the live IgD-CD27+IgG+CD20+CD3-CD14-CD16- compartment of the spleen of four organ donors, collected between 2015 and 2019. For all donors, both IgG+ memory B cell subsets were sorted alongside naïve B cells (IgD+CD27-CD38-CD24-CD20+CD3-CD14-CD16-). Assay for Transposase-Accessible Chromatin with high-throughput sequencing (ATAC-seq) was performed on 50000 cells of each sorted population, according to published methods (Buenrostro, Nature Methods, 2013, PMID: 24097267) and sent for library sequencing by Integragen (Evry, France). In parallel, RNA was extracted from remaining cells and sent for library preparation and sequencing by Integragen (Evry, France) (see related accession number).
