Age-Associated B Cells are Heterogenous and Dynamic in Autoimmunity

ABSTRACT: Age-Associated B Cells (ABCs) are a population of CD11c+ and/or CD11b+ B cells expanded in autoimmune lupus. To understand potential heterogeneity within ABCs and the relationship of ABCs to other splenic B cell subsets, we performed scRNA-seq with 5' V(D)J and CITE-seq cell surface features using the 10x Genomics Chromium platform on total splenic CD19+ B cells sorted from lupus-prone MRL/lpr. We found that ABC are a distinct transcriptional lineage that resolved into two related clusters. Analysis of BCR heavy chains identified clones present in both ABC and plasmablast compartments. Inferred lineage trees based on V gene somatic hypermutation suggested that self-renewing ABC feed into the plasmablast compartment repeatedly while continuing to themselves undergo mutation and expansion.

Identification of common lupus-disease related microRNA expression pattern in three different murine models of lupus

Project description:In this study, miRNA expression in splenic lymphocytes from three genetically disparate lupus-prone mouse models (MRL-lpr, B6-lpr and NZB/WF1) were profiled. 49 miRNAs were found to be differentially expressed in MRL-lpr mice compared to MRL mice; and 24 miRNAs were differentially expressed in B6-lpr mice compared to B6 mice. Among these dysregulated miRNAs, we noted that 15 miRNAs were common to both lpr strains. Interestingly, microarray analysis of NZB/W and NZW at 3 months of age, an age when overt lupus disease is not evident in NZB/W mice, revealed that only one miRNA, miR-148a was significantly upregulated in NZB/W mice. The aim of this porject is to determine the common miRNA expression changes in splenocytes from different strains of murine lupus models. The splenocytes were prepared from genetically lupus-prone female mice including MRL/MpJ-Faslpr/J (MRL-lpr), NZBWF1/J (NZB/W), B6.MRL-Faslpr/J (B6-lpr) and their control mice MRL/MpJ (MRL), NZW/LacJ (NZW) and C57BL/6J (B6) mice (The Jackson laboratory, ME). Total RNAs, containing miRNAs were isolated from whole splenocytes using mirVana miRNA isolation kits (Ambion) following manufactory’s instructions and sent to LC Sciences (http://www.lcsciences.com/) for the microarray assay. The mouse miRNA array chips (Chip ID miRMouse 12.0 version), which included 617 unique, mature, mouse miRNA, based on the Sanger miRBase Release 12.0, were used in the assay.

miRNAs expression in the splenic CD4+ T cells and B cells isolated from MRL/lpr mice at 5 and 16 weeks of age

Project description:To identify any differentially expressed miRNAs in the CD4+ T cells of lupus. MicroRNAs (miRNAs) have been implicated as fine-tuning regulators controlling diverse biological processes at the level of posttranscriptional repression. Dysregulation of miRNAs has been described in various disease states, including human lupus. By using high-throughput microRNA profiling analysis, we identified that two miRNAs (miR-21 and miR-148a) overexpressed in CD4+ T cells from both lupus patients and lupus-prone MRL/lpr mice,which promote cell hypomethylation by repressing DNA methyltransferase 1 (DNMT1) expression. We isolated the splenic CD4+ T cells and B cells from MRL/lpr mice at 5 and 16 weeks of age.Cells were collected and total RNA was extracted for the TaqMan® Low Density Assay v2.0 Normalization was performed with snoRNA202, reference snRNAs for mouse.Comparative real-time PCR was performed in triplicate, including no-template.controls. Relative expression was calculated with the comparative cycle threshold method.

Microarray for B cells of TACI-IgG-treated MRL/lpr mice compared to control mice

Project description:Both multiple myeloma (MM) and systemic lupus erythematosus (SLE) are characterized with abnormal production of plasma cells. In both diseases, the process of B cells differentiate into plasmablast/plasma cell is disordered. Despite the continuous research on the development of prognostic factors and introduction of new agents, dysregulation of plasmablast/plasma cells in MM and SLE is still uncontrolled. Thus, it is necessary to explore the novel therapeutic target to plasmablast/plasma cells. We and other researchers have shown that BAFF inhibitor atacicept (TACI-IgG), leads to some degree of B cell depletion. BAFF-specific targeted therapy specifically affects early-stage B cells in the periphery without affecting late-stage compartments such as plasma cells. Specifically depletion of plasma cells could hold great potential for the treatment of autoimmune diseases. To explore the novel therapeutic target to plasma cells, we determined the gene expression profile in B cells (mainly plasma cells) from atacicept (TACI-IgG)-treated lupus-prone MRL/lpr mice by affymetrix microarrays.

Remodeling of Mouse Hippocampus Genomic Fabrics in Neuropsychiatric Systemic Lupus Erythematosus

Project description:TNF-like weak inducer of apoptosis (TWEAK) and its cognate receptor Fn14 have been shown to play an important role in neurocognitive dysfunction in murine lupus. We profiled and compared gene expression in the hippocampi of MRL/+, MRL/lpr and MRL/lpr-Fn14 knockout (Fn14ko) adult female mice to determine the transcriptomic impact of TWEAK/Fn14 on hippocampal gene expression in lupus. We found that the TWEAK/Fn14 pathway strongly affects the expression level, variability and coordination of the genomic fabrics responsible for neurotransmission and chemokine signaling. Dysregulation of the PI3K-Akt pathway in the MRL/lpr lupus strain compared with the MRL/+ control and Fn14ko mice was particularly prominent and therefore promising as a potential therapeutic target, although the complexity of the transcriptomic fabric highlights important considerations in in vivo experimental models.

Diagnosis and early detection of CNS-SLE in MRL/lpr mice using peptide microarrays (GPL14921)

Project description:We investigated whether mouse serum autoantibody binding patterns on random-sequence peptide microarrays (immunosignaturing) can be used for diagnosing and predicting the onset of lupus and its central nervous system (CNS) manifestations. Submitter states "We have no processed data to submit. We have no gpr files to submit." To identify possible predictive and diagnostic peptides of lupus and CNS-lupus, we carried out two studies and selected peptides in common across both studies. In the first study we tested 3-6 MRL/lpr, MRL/mp and C3H/HeJ mice at four months of age. For study two we tested 9-10 MRL/lpr and MRL/mp at 1.5 and 4 months of age. In both studies the mice sera were diluted 1/500 and analyzed using microarray peptides from platform GPL14921. We ran each sample in triplicate. The MRL/lpr and MRL/mp are the autoimmune strains and the C3H/HeJ is the control strain.

Remodeling of Neurotransmission and Chemokine Signaling Genomic Fabrics in Neuropsychiatric Systemic Lupus Erythematosus

Project description:Cognitive dysfunction and mood changes are prevalent and especially taxing issues to patients with systemic lupus erythematosus (SLE). TNF-like weak inducer of apoptosis (TWEAK) and its cognate receptor Fn14 have been shown to play an important role in neurocognitive dysfunction in murine lupus. We profiled and compared gene expression in the cortices of MRL/+, MRL/lpr and MRL/lpr-Fn14 knockout (Fn14ko) adult female mice to determine the transcriptomic impact of TWEAK/Fn14 on cortical gene expression in lupus. We found that the TWEAK/Fn14 pathway strongly affects the expression level, variability and coordination of the genomic fabrics responsible for neurotransmission and chemokine signaling. Dysregulation of the PI3K-Akt pathway in the MRL/lpr lupus strain compared with the MRL/+ control and Fn14ko mice was particularly prominent and therefore promising as a potential therapeutic target, although the complexity of the transcriptomic fabric highlights important considerations in in vivo experimental models.

RNA Sequencing Facilitates Quantitative Analysis of Lupus (MRL/lpr) and Control（MRL/mpj）Mouse Microglia Tanscriptomes

Project description:Up to 75% of systematic lupus erythematosus (SLE) patients experience neuropsychiatric (NP) symptoms, called neuropsychiatric SLE (NPSLE), yet the underlying mechanisms remain elusive. Microglia control synaptic pruning during early postnatal brain development. The process in NPSLE remains unclear. Here, we show that microglia-coordinated elimination of synaptic terminals participated in NPSLE in MRL/lpr mice, a lupus-prone murine model. We elucidated that lupus mice developed increased depression- and anxiety-like behaviors and persistent phagocytic microglia reactivation before overt peripheral lupus pathology. Microglial engulfment of synapses explained behavioral disorders. To elucidate the mechanism of synaptic pruning by microglia, we sequenced the gene expression in sorted microglia from both lupus (MRL/lpr) mice and the wild-type (MRL/mpj) controls.

Evaluation of microRNA levels in recipient BMMSCs of MRL/lpr mice after cell therapy (miRNA)

Project description:Mesenchymal stem cell transplantation (MSCT) has been widely used to treat a variety of human diseases. However, the detailed mechanisms underlying its success are not fully understood. Here we show that MSCT rescues recipient bone marrow mesenchymal stem cell (BMMSC) function in Fas-deficient-MRL/lpr systemic lupus erythematosus (SLE) mice via a miR-29b/Dnmt1/Notch epigenetic cascade. Using the microRNA microarray, we found that MSCT could rescue the high level of miR-29b in the recipient BMMSCs of MRL/lpr mice. In the present study, mesenchymal stem cell transplantation (MSCT) was used to treat MRL/lpr mice. One week after the treatment, normal control MSCs from C3H/HeJ mice (C3H), recipient MSCs from untreated MRL/lpr mice (LPR) and recipient MSCs from MSCT-treated MRL/lpr mice (MSC) were used for total RNA extraction and microRNA microarray for analysis of microRNA expressions.

Evaluation of global methylation profile in recipient BMMSCs of MRL/lpr mice after cell therapy (MeDip)

Project description:Mesenchymal stem cell transplantation (MSCT) has been widely used to treat a variety of human diseases. However, the detailed mechanisms underlying its success are not fully understood. Here we show that MSCT rescues recipient bone marrow mesenchymal stem cell (BMMSC) function in Fas-deficient-MRL/lpr systemic lupus erythematosus (SLE) mice via rescuing their hypomethylated DNA profile. Using the methylation microarray, we found the global hypomethylation pattern in the recipient BMMSCs of MRL/lpr mice could be rescued by MSCT. In the present study, mesenchymal stem cell transplantation (MSCT) was used to treat MRL/lpr mice. One week after the treatment, normal control MSCs from C3H/HeJ mice (C3H), recipient MSCs from untreated MRL/lpr mice (LPR) and recipient MSCs from MSCT-treated MRL/lpr mice (MSC) were used for total DNA extraction and DNA methylation microarray for analysis of global genome methylation patterns.
