(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) Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by autoantibody production and immune complex deposition. Previous evidence showed abnormal accumulation of B cells in the thymus of lupus-prone mice, but the role of this population remains undefined. We analyzed the distribution, function, and properties of thymic B cells in the BWF1 murine model of SLE. We found that B cells proliferate and cluster in germinal center-like structures along with autoantibody-secreting cells in the thymus of diseased-BWF1 mice. 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) Protein phosphatase 2A (PP2A), a serine/threonine phosphatase, has been shown to control T cell function. We found that in vitro activated B cells and B cells from various lupus-prone mice and patients with systemic lupus erythematosus display increased PP2A activity. To understand the contribution of PP2A to B cell function, we generated a Cd19CrePpp2r1aflox/flox (flox/flox) mouse which lacks functional PP2A only in B cells. more...

(Submitter supplied) Systemic lupus erythematosus (SLE) is an autoimmune disorder characterized by failure of self-tolerance mechanisms and the resultant production of autoreactive antibodies. The NZBWF1 mouse spontaneously develops a lupus-like syndrome and is used as model of SLE. The NZBWF1 model represents the F1 generation of a cross between New Zealand Black (NZB) and New Zealand White (NZW) mice. In this study we investigated the model and its progenitors (NZB, NZW) gene expression with single cell RNA sequencing on cells isolated from bone marrow and processed with the 10X Chromium.

(Submitter supplied) Systemic lupus erythematosus (SLE) is a complex autoimmune disease with significant morbidity - demanding further examination of tolerance inducing treatments. Short-term treatment of lupus-prone NZB/WF1 mice with combination CTLA4Ig and anti-CD40L but not single treatment alone, suppresses disease for > 6 months via modulation of B and T cell function while maintaining immune responses to exogenous antigens. more...

(Submitter supplied) The microphthalmia transcription factor Mitf has been shown to regulate B cell activation and tolerance. However, the underlying B cell-specific mechanisms responsible, and those that distinguish Mitf from closely related Mitf/TFE (MiT) transcription factors Tfe3, Tfeb, and Tfec, remain obscure. Two complementary mouse models of Mitf and MiT deficiency – the Mitfmi-vga9/mi-vga9 systemic loss-of-function mutation, and B-cell specific MiT family inactivation via transgenic expression of a trans-dominant negative (TDN) protein (TDN-B) – were used to identify MiT family candidate target genes and pathways. more...

(Submitter supplied) Sle2c1 is an NZM2410-derived lupus susceptibility locus that induces an expansion of the B1a cell compartment. B1a cells have a repertoire enriched for autoreactivity, and an expansion of this B cell subset occurs in several mouse models of lupus. Here we showed that expression of Sle2c1 enhances NZB cellular phenotypes that have been associated with autoimmune pathogenesis. A combination of genetic mapping and candidate gene analysis presents Cdkn2c, a gene encoding for cyclin kinase inhibitor p18INK4c (p18), as the top candidate gene for inducing the Slec2c1 associated expansion of B1a cells. more...

Analysis of peritoneal cavity B cells (B1a) and splenic B (sB) cells from B6.Sle2c1 mice. Sle2 induces expansion of the B1a cell compartment, a B cell defect consistently associated with lupus. Results provide insight into molecular mechanisms underlying susceptibility to lupus in the NZM2410 model.
