Analysis of splenocytes from WT, B6.Sle1.Sle3 (lupus mice) and B6.Sle1.Sle3 Tcf4+/− (Sle/het) mice haplodeficient for the transcription factor E2-2 (Tcf4). E2-2 is a specific regulator of plasmacytoid dendritic cell (pDC) development. Results provide insight into role of pDC in SLE pathogenesis.

(Submitter supplied) Systemic lupus erythematosus (SLE) is an autoimmune disorder characterized by the production of antibodies to self-nucleic acids, immune complex deposition and tissue inflammation such as glomerulonephritis. Innate recognition of molecular complexes containing self-DNA and RNA and the ensuing production of type I interferons (IFN) contribute to SLE development. Plasmacytoid dendritic cells (pDCs) have been proposed as a relevant source of pathogenic IFN in SLE; however, their net contribution to the disease remains unclear. more...

(Submitter supplied) Mature neutrophis were freshly isolated from blood of pediatric systemic lupus erythematosus (SLE) patients and healthy donors. Illumina microarray was used to assess transcriptional changes between SLE group and Control group. To uderstand further the gene expression difference between SLE and healthy neutrofils, neutrophils from healthy donors were cultured with autologous sera, SLE sera or Interferon and microarray data was used to compare with fresh SLE neutrophils.

(Submitter supplied) The interferon-producing plasmacytoid dendritic cells (PDC) share common progenitors with antigen-presenting classical dendritic cells (cDC), yet they possess distinct morphology and molecular features resembling those of lymphocytes. It is unclear whether the unique cell fate of PDC is actively maintained in the steady state. We report that the deletion of transcription factor E2-2 from mature peripheral PDC caused their spontaneous differentiation into cells with cDC properties. more...

(Submitter supplied) Systemic Lupus Erythematosus (SLE) is among the most sex-biased autoimmune diseases identified to date, affecting 9-times more women than men. Recognition of self-RNA by Toll-like receptor 7 (TLR7) is implicated as a central pathogenic process leading to the aberrant production of type-I interferon (IFN) in SLE, but the specific RNA molecules contributing to this process have not been defined. Given the role of self-RNA and biological sex in SLE pathogenesis, we investigated which sex-biased self-RNAs are potentially responsible for aberrant TLR7 activation in SLE. more...

(Submitter supplied) Autoantibodies to nuclear antigens are hallmarks for diagnosis of the autoimmune disease systemic lupus erythematosus (SLE) and they contribute to SLE pathogenesis. However, there remains a gap in our knowledge regarding how different isotypes of autoantibodies contribute to key disease processes, including the production of the critical type I interferon (IFN) cytokines by plasmacytoid dendritic cells (pDCs) in response to immune complexes (ICs). more...

(Submitter supplied) Stimulation experiments were done with PBMC from SLE or healthy donors treated with CSL362 or isotype control before stimulation with various stimuli including the TLR9 agonist 0.25 μM CpGc; the TLR4 agonist 10 μg/ml LPS; and the TLR3 agonist 10 μg/ml POLY I:C. As well as the SLE specific stimuli SLE immunoglobulin (Ig) + necrotic cell lysates (NCL) to form immune complexes; control healthy donor Ig + NCL; and SLE sera + NCL; or healthy donor sera + NCL to understand the specific effects of pDC depletion on different inducible gene transcripts.
