IL-7R signalling activates widespread VH and DH gene usage to drive antibody diversity in bone marrow B cells

Project description:Generation of the primary antibody repertoire requires V(D)J recombination of hundreds of gene segments in the immunoglobulin heavy chain (Igh) locus. It has been proposed that interleukin-7 receptor (IL-7R) signalling is necessary for Igh recombination, but this has been challenging to partition from the receptor’s role in B cell survival and proliferation. By generating the first detailed description of the Igh repertoire of murine IL-7Ra-/- bone marrow B cells, we demonstrate that IL-7R signalling profoundly influences VH gene selection during VH-to-DJH recombination. We find skewing towards usage of 3’ VH genes during de novo VH-to-DJH recombination that is more severe than the fetal liver (FL) B cell repertoire, and we now show a role for IL-7R signalling in DH-to-JH recombination. Transcriptome and accessibility analyses suggests reduced expression of B lineage-specific transcription factors (TFs) and their targets, and loss of DH and VH antisense transcription in IL-7Rα-/- B cells. These results refute models suggesting that IL-7R signalling is only required for survival and proliferation, and demonstrate a pivotal role in shaping the Igh repertoire by activating underpinning epigenetic mechanisms.

High-throughput sequencing of the IGH repertoire in human peripheral blood and bone marrow

Project description:We applied high-throughput sequencing of the IGH repertoire in peripheral blood and bone marrow (BM) of a primary immunodeficiency patient. We obtained 325994 IGH sequences from the BM sample and 72597 IGH sequences from the peripheral blood. After comparing with IMGT/GENE-DB database (http://www.imgt.org), we found obviously increased CDR3 clonality in the patient BM as compared to his peripheral blood. Furthermore, the frequency of IgG transcripts in the patient BM was higher than that in the peripheral blood while the frequency of IgM transcripts was similar.

Bone Marrow Transplantation in Treating Patients With Hematologic Cancer

Project description:RATIONALE: Radiation therapy uses high-energy x-rays to damage cancer cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation in treating patients who have hematologic cancer.

Expression data from mouse bone marrow late pre-B cells

Project description:B-cell development in the bone marrow proceeds through phenotypically defined stages. At the pre-B cell stage, cells stop cycling and rearrange the light chain of immunoglobulin. There are notable defects in the number of these cells and subsequent stages of B-cell development in mice with hematopoietic deficiency of the gene Ddx3x, when compared to wildtype control mice. We used microarrays to determine differences in gene expression between bone marrow pre-B cells in wild-type mice and those deficient in Ddx3x in hematopoietic cells (Vav1-cre x Ddx3x-floxed, male, hemizygous)

Bone marrow-selected antigen specific regulatory B cells

Project description:Autoimmunity is often regarded as pathogenic, but this view has gradually shifted over time. Based on insights from thymus selection, T cells are now known to be selected by self-antigens and positive selection in the thymus medulla leads to regulatory functions. B cells are selected in the bone marrow and the fundamental question is whether self-antigens in the bone marrow select antigen specific regulatory B cells. In this work, we show that B cells are indeed selected for proteins expressed in the bone marrow and develop into cells with regulatory function bearing distinct phenotypic fingerprint. Collagen type II specific regulatory B cells trigger the expansion of antigen specific regulatory T cells and protect against development of tissue specific autoimmune inflammation. These antigen specific regulatory B cells constitute a sizeable fraction of the normal B cell repertoire in both mice and humans.

The bone marrow microenvironment of pre-B acute lymphoblastic leukemia at single-cell resolution

Project description:The bone marrow microenvironment of leukemia plays a key role in leukemia progression, but its molecular complexity in pre-B acute lymphoblastic leukemia (B-ALL), the most common cancer in children, remains poorly understood. Here we use single-cell RNA sequencing to characterise the bone marrow microenvironment during B-ALL progression.

Gene expression profile at single cell level of pre-cDCs from the bone marrow, spleen and lung of mice

Project description:Type 2 pre-cDCs are considered as a homogeneous population in the bone marrow. We used single cell RNA sequencing to show that the bone marrow contains two subsets of pre-cDC2s that are commited to give rise to different different cDC2 subsets in peripheral tissues.
