Marginal zone B cells receive robust Notch2 signals within the B cell follicle in the absense of S1pr1 signaling.

ABSTRACT: Marginal zone (MZ) B cells have innate-like response characteristics due to a unique ability receive and integrate Notch2 signals in the spleen. There is evidence showing MZ B cells receive these signals both in the marginal sinus and the B cell follicle. The relative strength and conservation of these Notch signals is not yet clear. Therefore, we generated mice in which S1pr1 is deleted in mature B cells. These mice have MZ B cells by phenotype but these cells are retained in the follicle and unable to transit to the marginal zone. In this experiment we examined the impact of Notch2 signaling in these cells and cre expressing control animals using in vivo anti-Notch2 antibody blockade followed by RNA-sequencing.

Identification of Myc-dependent and -independent Notch2 signatures in marginal zone B cells.

Project description:Marginal zone (MZ) B cells leverage Notch2 signals to attain rapid differentiation responses and positional cues with in the spenic environment. While it is known that a major player in Notch2 signaling in MZ B cells is the proto-oncogene Myc, it is not clear to what extent MZ B cells use Notch2 signals in Myc-independent manner. In this study we conditinally and inducibly deleted Myc in mature B cells and then used in vivo delivery of anti-Notch2 antibodies to separated Myc-dependent and -independent Notch2 signaling in MZ B cells.

Transcriptomic analyis follicular and marginal zone B ells after in vivo Notch2 blockade.

Project description:Marginal zone B cells which make rapid mitosis-independent plasma cell responses are dependent on Notch2 signaling for their generation and maintenance. In order to determine the effect of ongoing Notch signaling on the maintenance of the MZ transcriptome, we performed RNA-seq on MZ and follicular B cells after 12, 24 and 48 hours of in vivo Notch2 antibody blockade

Identification of Notch ligand useage by splenic B cells using Dll1 and Dll4 Notch ligand blockade.

Project description:Marginal zone (MZ) B cells leverage Notch2 signals to attain rapid differentiation responses and positional cues with in the spenic environment.To determine the likely molecular source of Notch2 signals we sought to block the Notch ligands delta-like ligand 1 (Dll1) and delta-like ligand 4 (Dll4) in wildtype mice using in-vivo treatment with monoclonal blocking antibodies. Splenic populations of MZ B cells and follicular B cells were sort purified after 12, 24 and 48 hours of blockade and analyzed by RNA-seq.

Gene expression profiles from human splenic Marginal Zone and Naive (Follicular) B cells

Project description:Splenic Marginal Zone B cells mount innate-like T cell-independent (TI) antibody responses to blood-borne antigens upon receiving activation signals from TACI-engaging factors BAFF and APRIL. The transcriptome analysis of splenic Marginal Zone (MZ) B cells was performed to verify which transcriptional programs are enhanced in the innate-like MZ B cell subset and to study the involvement of mTOR in MZ B cells activated via TACI.

Transcriptomic analyis of donor (B6:SJL.C20) and host follicular and marginal zone B cells after adoptive transfer of follicular B cells into into lymphopenic (Rag2-/-) or replete animals (C57BL6)

Project description:The generation of marginal zone (MZ) B cells is a Notch2 dependent process. We observed that transdifferentiation of follicular (FO) B cells to an MZ-like phenotype is dependent on a lymphopenic environment. We therefore adoptively transftered congenically marked SJL.C20 (CD45.1) mature naive FO B cells into either lymphopenic Rag2-/- or intact C57BL6 (CD45.2) recipient mice and recovered and double sorted intermediate phenotype (MZ-FO) donor B cells at day 4 post transfer from Rag2-/- recipients or both MZ and FO phenotype donor B cells at day 8 post transfer from both recipient groups and performed RNA sequencing.

Genome-Wide Analysis of Splenic Marginal Zone Lymphoma

Project description:<p>Splenic Marginal Zone Lymphoma (SMZL) is a B-cell malignancy of unknown pathogenesis and thus orphan of targeted therapies. By integrating whole-exome sequencing and copy-number analysis of 8 paired tumor-normal DNAs from patients with SMZL, we show that the typical SMZL exome carries ~30 genetic alterations. Targeted resequencing of selected candidates in an extended panel of 40-117 samples revealed activating mutations of NOTCH2, a gene required for marginal-zone (MZ) development, as the most frequent and SMZL-specific lesion, accounting for approximately 20% of cases. Additional altered genes suggest that deregulation of signaling pathways normally involved in MZ development (NOTCH, NF-kappa B, and B-cell receptor) represents a critical event in SMZL pathogenesis. These findings have direct implications for the treatment of SMZL patients since drugs are available which can target NOTCH as well as other pathways deregulated in this disease.</p>

Project description:Marginal zone B cells can quickly respond to the bacterial invasion by providing the first-line of antibodies. Neutrophil can help marginal zone B cells activation and differentiation. We investigated the specific gene expression that interacts between the MZ B cells and neutrophils at the initial stage after Staphylococcus aureus infection.
