MRNA-seq of AID-expressing cells from mice infected with WT or M2.Stop 73.Bla MHV68

ABSTRACT: Gammaherpesviruses (GHV) are DNA tumor viruses that establish lifelong latent infections in lymphocytes. For viruses such as Epstein-Barr virus (EBV) and murine gammaherpesvirus 68 (MHV68), this is accomplished through a viral gene-expression program that promotes cellular proliferation and differentiation, especially of germinal center (GC) B cells. Intrinsic host mechanisms to control virus-driven cellular expansion are incompletely defined. Using a small-animal model of GHV pathogenesis, we identify the B cell-specific latency gene M2, an MHV68 mediator of GC B cell differentiation, as a viral gene product that is sufficient to induce p53 in a manner that is dependent on Src kinase activity. To understand the function of M2 in germinal center B cells in vivo, we infected AID-cre tdTomato reporter mice with WT or M2.Stop 73.Bla MHV68. At 16 dpi, draining lymph nodes were harvested and treated with CCF4-AM. AID+ and AID+Bla+ lymphocytes were sorted from WT and M2.Stop MHV68 infected tissue and sent for ultra-low input RNA-seq analysis.

mRNA-seq of wild-type or p53-deficient B cells expressing MHV68 M2

To understand the function of M2 in primary B cells, we performed retroviral transduction of M2 or M2.Stop in wild-type or p53-deficient B cells. Our results reveal p53 and cellular proliferation pathways enriched in M2-expressing B cells.

Transcription factor Ascl2 promotes geminal center B cell responses through directly regulating AID transcription

Project description:During germinal center (GC) reactions, activated B cells undergo clonal expansion and functional maturation to produce high-affinity antibodies, and differentiate into plasma and memory cells, accompanied with class-switching recombination (CSR) and somatic hypermutation (SHM). Activation-induced deaminase (AID) is responsible for both CSR and SHM in GC B cells. Transcriptional mechanisms underlying AID regulation and GC B cell reactions are still not well understood. Here, we show that expression of Ascl2 transcription factor is upregulated in GC B cells. Ectopic expression of Ascl2 promotes GC B cell development and enhances antibody production as well as affinity maturation. Conversely, deletion of Ascl2 in B cells impairs the germinal center response. Genome-wide analysis reveals that Ascl2 directly regulates GC B cell-related genes, including AID; ectopic expression of AID in Ascl2-deficient B cells rescues their antibody defects. Thus, Ascl2 regulates AID transcription and promotes germinal center B cell responses.

DNA Methylation Dynamics of Germinal Center B Cells Are Mediated by AID

Project description:Changes in DNA methylation are required for the formation of germinal centers (GC), but the mechanisms of such changes are poorly understood. Activation-induced cytidine deaminase (AID) has been recently implicated recently in DNA demethylation through its deaminase activity coupled with DNA repair. We investigated the epigenetic function of AID in vivo in germinal center B cells (GCB) isolated from wild type (WT) and AID-deficient (Aicda-/-) mice. We determined that the transit of B cells through the GC is associated with marked locus-specific loss of methylation and increased methylation diversity, both of which are lost in Aicda-/- animals. Differentially methylated cytosines (DMCs) between GCB and naïve B cells (NB) are enriched in genes that are targeted for somatic hypermutation (SHM) by AID and these genes form networks required for B cell development and proliferation. Finally, we observed significant conservation of AID-dependent epigenetic reprogramming between mouse and human B cells.

Transcriptional profiles of knockouts of m6A writer and readers in Germinal Center B cells

Project description:We performed RNA-seq (MARS-seq) on germinal center (GC) light zone and dark zone B cells sorted to purity from freshly dissociated mouse popliteal lymph nodes immunized with NP-KLH for 7 to 14 days. Germinal center B cell subsets were gated as follows: Dump (CD8, CD4, F4/80, Gr-1)- B220+ CD38- GL-7+ FAS+. Dark zone GC cells were in addition CD86lo, CXCR4hi; LZ cells were in addition CD86hi, CXCR4lo. Three different mouse models were used: AID-cre Mettl3-flox, AID-cre Ythdf2-flox, Igf2bp3-knockout. We used these data to derive differentially expressed genes between B cell subsets of control and knockout genotypes. We also performed m6A-IP on ex vivo activated wild type B cells and determined the m6A targets in B cells. These studies revealed that the GC response depends on m6A RNA methylation and the functions of specific methyl-readers Ythdf2 and Igf2bp3.

Id3 Orchestrates Germinal Center B Cell Development

Project description:Previous studies have demonstrated that E-proteins induce AID expression in activated B cells. Here we have examined the role of Id3 in germinal center (GC) cells. We found that Id3 expression is high in follicular B-lineage cells but declines in GC cells. Immunized mice depleted for Id3 expression displayed a block in germinal center B cell maturation, showed reduced numbers of marginal zone B cells and class switched cells, were associated with decreased antibody titers and lower numbers of plasma cells. In vitro Id3-depleted B cells displayed a defect in class switch recombination. Whereas AID levels were not altered in Id3-depleted activated B cells, the expression of a subset of genes encoding for signaling components of antigen receptor, cytokine receptor and chemokine receptor mediated signaling was significantly impaired. We propose that during the GC reaction Id3 levels decline to activate the expression of genes encoding for signaling components that mediate B cell receptor and or cytokine-mediated signaling to promote the differentiation of GC B cells.

Mettl1-mediated B cell responses

Project description:Germinal center (GC) response requires increased protein synthesis. We identify the methyltransferase METTL1 as a translational checkpoint during GC responses. Therefore, we immunized mettl1-cko mice and control mice with NP-OVA, and sorted spleen B cells on day 14.

Transcription profiling of mouse naive B cells and gernimal center B cells

Project description:Activation-induced cytidine deaminase (AID) is essential for the generation of antibody memory but also targets oncogenes among others. We investigated the transcriptional regulation of the AID gene, Aicda, in the class switchâinducible CH12F3-2 cells, and found that the Aicda regulation involves derepression by several layers of positive regulatory elements in addition to the 5â promoter region. The 5â upstream region contains functional motifs for the response to signaling by cytokines, CD40-ligand, or stimuli that activate NF-ÎºB. The first intron contains functional binding elements for the ubiquitous silencers c-Myb and E2f and for B cellâspecific activator Pax5 and E-box-binding proteins. To confirm involvement of these transcription factors in Acida regulation, we examined their expression profile of these factors in naÃ¯ve and germinal center B cells. Experiment Overall Design: NaÃ¯ve B cells were defined as B220+PNA-Fas- and germinal center B cells were defined as B220+PNA+Fas+ cells. These cells were purified from immunized mouse lymph nodes or mouse Peyer's patches by using FACS Aria. Samples are as follows: pLN GC, pLN naÃ¯ve, PP GC, PP naÃ¯ve, (each 1 sample, prepared from pooled 3-5 mice)

Non-apoptotic Fas signaling controls CD40 dependent mTOR activation and human B cell fate via PTEN nuclear exclusion

Project description:Defective Fas signaling causes autoimmune lymphoproliferative syndrome (ALPS). While defective apoptosis may impair negative selection and removal of autoreactive B lymphocytes, Fas transmits also non-apoptotic signals. We show herethat transient Fas ligation in CD40L-stimulated human B cells specifically decreased the mTOR axis activation without causing apoptosis. This signal modulation was absent in ALPS patients. Rather, mTOR signaling was enhanced in germinal center (GC) B cells and plasmablasts derived from a ALPS patient lymph node . Mechanistically, transient Fas engagement induced recruitment of DAXX to the activated Fas complex and nuclear exclusion of PTEN. Likewise, Fas stimulation promoted expression of transcripts like MYC and CXCR4, that regulate GC formation and fate decisions of established GC B cells. We suggest that non-apoptotic Fas signaling has a physiological impact on activated B cell fate decisions explaining the effectiveness of mTOR inhibitors in the treatment of ALPS autoimmunity.
