(Submitter supplied) Sle1c is a sublocus of the NZM2410-derived Sle1 major susceptibility locus. We have previously shown that Sle1c contributes to lupus pathogenesis by conferring CD4+ T cell-intrinsic hyperactivation and increased susceptibility to chronic graft-versus-host disease (cGVHD) that mapped to the centromeric portion of the locus. In this study, we have refined the centromeric sublocus to a 675Kb interval, termed Sle1c2. more...

(Submitter supplied) Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare SLE patients to Health donors PBMCs-derived transcriptome profiling (RNA-seq) to microarray and quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods and to discovery the potential pathway which can be used as a therapeutic target.

(Submitter supplied) Background: Dendritic cells (DCs) are critical for regulating CD4 and CD8 T cell immunity, controlling Th1, Th2, and Th17 bias, generating inducible Tregs, and inducing tolerance. Multiple DC subsets have been identified in the mouse that are thought to have evolved to control these different immune outcomes. However, how these subsets differentially respond to inflammatory and/or tolerogenic signals in order to accomplish their divergent functionality remains unclear. more...

(Submitter supplied) Recent literature has shown that neutrophils exert significant influence on the course of disease progression in lupus, but there is currently controversy in the lupus field regarding a) whether neutrophils are predominantly protective or deleterious toward the propagation of auto-reactivity, b) the specific mechanism of neutrophil influence on adaptive immune dysregulation, and c) identity and origin of functionally abnormal neutrophil subsets in lupus. more...

(Submitter supplied) Microarray analysis was performed on BWF1 mice spleenocyte cells in control and pCONS treated mice. Microarray analysis identified many genes differentially expressed in control vs pCONS treated mice spleenocytes. Some of the genes were uperegulated and some of the genes were down regulated. Microarray analysis was performed in CD4, CD8, and whole spleenocyte WBC cells. Keywords: One week after pCONS injection

(Submitter supplied) Loss of the interactions between lymphotoxin and its receptor was associated with MZM apoptotic cell clearance defects in BXD2 mice whereas loss of IFNAR in BXD2 mice normalized the function of MZMs. The analysis also intended to use MZMs isolated from BXD2-Ifnar-/- mice and BXD2 mice treated with sLTbR-Fc to identify the common pathways regulating the MZM function in these mice.

(Submitter supplied) A better understanding of the mechanisms involved in human plasma cell differentiation will accelerate therapeutic target identification in autoantibody-mediated diseases such as Systemic Lupus Erythematosus (SLE). Here, we describe a novel CXCR5- CXCR3+ PD1hi CD4+ T cell ‘helper’ population distinct from follicular helper T cells (Tfh) and expanded in blood and inflamed kidneys of SLE patients. Upon activation, these cells express IFNand high levels of IL10. more...

Here, we describe a novel CXCR3+ PD1hi CD4+ T cell ‘helper’ population expanded in blood and inflamed kidneys of SLE patients. Upon activation, these cells express IFNg and IL10 and display high levels of mitochondrial ROS (mtROS) as the result of reverse electron transfer (RET) fueled by succinate. more...

(Submitter supplied) Autoantibodies against nucleic acids are a hallmark of Systemic Lupus Erythematosus. We recently uncovered that human oxidized DNA of mitochondrial origin released by activated lupus neutrophils represents a distinct class of interferogenic TLR9 ligand for plasmacytoid dendritic cells. We now show that oxidized mitochondrial DNA-activated plasmacytoid dendritic cells skew naïve CD4+ T cells towards IL2low, IFNγhigh, IL10high secreting B helper cells different from follicular helper and Type 1 regulatory CD4+ T cells. more...

(Submitter supplied) Splenic long-lived plasma cells (PCs) are abnormally numerous and deleterious in systemic autoimmune diseases, yet how they accumulate remains poorly understood. We demonstrate here that a pathological role of spleen-derived CD11b+Gr-1+ myeloid cells (SPMCs) underpins the accumulation of splenic long-lived PCs in a lupus-prone model. SPMCs were a mixture of granulocytic and monocytic myeloid-derived suppressor cells (MDSCs) that were expanded and acquired proinflammatory phenotypes in situ during lupus progression. more...

(Submitter supplied) This experiment contains two mice genotypes – WT and Bcl3 flx/flx Zbtb46 cre knockouts (both C57BL/6 background). These mice were either infected with 15 cysts of Toxoplasma gondii (ME49 strain) or kept uninfected. Spleens were harvested from mice 7 days post infection and splenocytes were isolated. With four experimental groups (KO/WT and infected/uninfected) and two biological replicate mice per group, we have a total of 8 biological samples comprising of single cell suspensions of splenocytes enriched for CD11c. more...

(Submitter supplied) In lupus autoimmunity, pathogenic IgG autoantibodies that fix complement and bind FcGammaR on inflammatory cells, are produced with help from T helper (Th1 and Th17) cells specific for peptides from nucleosomes of apoptotic cells; and these Th cells also infiltrate vital organs (1-9). Macrophages (e.g. tingible body MΦ), and DCs are normally tolerant to apoptotic cell antigens (10), but they are activated to present such autoantigens after binding to IgG immune complexes (IC) containing apoptotic cell derived DNA/RNA, which then dually stimulate their TLR and FcGammaR (11-16). more...
