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.

(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...

(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) We have found many differences between B1a cells from p40-/-CD25-/- mice and control mice. To better understand the whole change of transcriptions profile between B1a cells in PC of p40-/-CD25-/- mice and control mice. By using flow cytometry and high-resolution microarrays, we have studied qualitative and quantitative characteristics of B1a cells of p40-/-CD25-/- mice and control mice.

(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) Lupus susceptibility results from the combined effects of numerous genetic loci, but the contribution of these loci to disease pathogenesis has been difficult to study due to the large cellular heterogeneity of the autoimmune immune response. We performed single cell RNA, B cell receptor (BCR), and T cell receptor (TCR) sequencing of splenocytes from mice with multiple polymorphic lupus susceptibility loci. more...
