Project description:LRF, which is encoded by the ZBTB7A gene and formerly known as POKEMON (POK erythroid myeloid ontogenic factor), was originally identified as a PLZF (promyelocytic leukemia zinc finger) homologue interacting with BCL6 (B-cell lymphoma 6). LRF is a transcription factor that is broadly expressed in hematopoietic lineage cells, but its expression is particularly high in erythroblasts and germinal center (GC) B-cells. The goal of this study is to assess the effect of LRF loss on the LT-HSC transcriptome. Nine days after injection of adult mice with polyinosinic polycytidylic acid (pIpc) to activate Cre, total RNAs were isolated from double-sorted LT-HSCs from LRF Flox/+ Mx1-Cre+ and LRF Flox/Flox Mx1-Cre+ mice and processed for microarray analysis. We performed gene expression microarray analysis of FACS-sorted LT-HSCs (LSK IL7Ra-Flt3-CD150+CD48-) to assess the effect of Lrf loss on the LT-HSC transcriptome. Zbtb7a Flox/+ Mx1-Cre+ mice were used as a control to normalize the potential effects of Cre recombinase. LT-HSCs were FACS-sorted from three Lrf knockout (Zbtb7a Flox/Flox Mx1-Cre+) and two control (Zbtb7a Flox/+ Mx1-Cre+) mice, nine days after the first pIpC injection.

Project description:The chemokines CXCL13 and CXCL12 are reported to be important for the germinal center reaction. Since CXCL12-deficient mice are embryonically lethal, here we took advantage of the Cxcl13-Cre/TdTomato mouse models to genetically ablate CXCL12 from B cell-interacting reticular cells and examine the molecular consequence on germinal center B cells. Spatial segregation of follicular dendritic cells, germinal center B cells and follicular helper T cells is impaired in Cxcl13-Cre/TdTomato Cxcl12fl/fl mice. Single cell transcriptomic analysis revealed that all germinal center B cell subsets (corresponding to distinct stages of the germinal center response) are present in draining lymph nodes of immunized CXCL12-conditionally deficient mice. While most transcriptional regulators of the germinal center response are unperturbed by the genetic perturbation of CXCL12, Bach2 levels were elevated in germinal center B cells from lymph nodes of Cxcl12fl/fl mice. Moreover, single cell B cell receptor sequencing revealed that germinal center B cells in Cxcl13-Cre/TdTomato Cxcl12fl/fl mice harbour a lower mutational burden when compared to germinal center B cells isolated from immunized control mice. Gene expression profiles were validated by flow cytometry and suggest that the provision of CXCL12 by reticular cells governs efficient germinal center responses.
