Project description:We previously showed that all-trans-retinoic acid (tRA), an active metabolite of vitamin A, exacerbated pre-existing autoimmunity in lupus; however, its effects before the development of autoimmunity are unknown. Here, using a pristane-induced model, we show that tRA exerts differential effects when given at the initiation vs. continuation phase of lupus. Unlike tRA treatment during active disease, pre-pristane treatment with tRA aggravated glomerulonephritis through increasing renal expression of pro-fibrotic protein laminin β1, activating bone marrow conventional dendritic cells (cDCs), and upregulating the interaction of ICAM-1 and LFA-1 in the spleen indicating an active process of leukocyte activation and trafficking. Transcriptomic analysis revealed that prior to lupus induction, tRA significantly upregulated the expression of genes associated with cDC activation and migration. Post-pristane tRA treatment, on the other hand, did not significantly alter the severity of glomerulonephritis; rather, it exerted immunosuppressive functions of decreasing circulatory and renal deposition of autoantibodies as well as suppressing the renal expression of proinflammatory cytokines and chemokines. Together, these findings suggest that tRA differentially modulate lupus-associated kidney inflammation depending on the time of administration. Interestingly, both pre- and post-pristane treatments with tRA reversed pristane-induced leaky gut and modulated the gut microbiota in a similar fashion, suggesting a gut microbiota-independent mechanism by which tRA affects the initiation vs. continuation phase of lupus.

Project description:To identifiy stage-dependent genes in Sertoli cells, we performed expression microarray analysis of the adult whole testes, cultured primary Sertoli cells, Sertoli cells directly isolated from wild-type and Nanos3 (germ-less) testes,seminiferous tubules at stages I-III, IV-VI, VII-VIII and IX-XII. Next to examine the relationship between stage-dependent gene expression change and retinoic acid signaling, we performed expression microarray analysis of the cultured primary Sertoli cells treated with retinoic acid and stage-specific seminiferous tubules injected with lentivirus containing Venus or dominat negative form of RARa, a dominant receptor for retinoic acid in Sertoli cells.

Project description:We characterized the longitudinal gene expression profiles of whole blood from a novel lupus model nephritis: SNF1 (SWR X NZB F1) mice treated with pristane. Genes from interferon, plasma cell, neutrophil, T-cell and protein synthesis signatures were differentially expressed in the pristane-SNF1 model compared to the untreated matched control animals.

Project description:Low capacity to produce reactive oxygen species (ROS) due to mutations in neutrophil cytosolic factor 1 (NCF1/p47phox) is strongly associated with lupus development both in humans and mouse models. Here, we aim to identify the major mechanisms of the Ncf1-disease association. We found that plasmacytoid dendritic cells (pDCs), the most potent producers of type I IFNs, exacerbate pristane-induced lupus in ROS-defective Ncf1-mutant and human NCF1-339 variant carrying mice. ROS deficiency in mouse models with Ncf1 mutation or human NCF1-339 variant leads to enhanced pDC generation via the TLR7/AKT/mTOR pathway and accumulation at sites of inflammation, resulting in an increased IFNα secretion. The produced IFNα further stimulates the JAK1/STAT1 pathway, which we found is hyperreactive in ROS-deficient pDCs. This, in turn, leads to increased type I IFN signature and enhanced proinflammatory responses. Our discoveries explain the causative effect of dysfunctional Ncf1 and pathogenicity of pDCs in lupus.

Project description:We characterized the longitudinal gene expression profiles of kidneys from a novel lupus model nephritis: SNF1 (SWR X NZB F1) mice treated with pristane. Genes from biological processes such as IFN response, complement, Fc gamma receptors, immune recruitment, innate immune pattern recognition, antibody response and fibrosis,were upregulated in diseased kidneys.

Project description:Retinoic acid (RA) is an important developmental signaling molecule responsible for the patterning of multiple vertebrate tissues. RA is also a potent teratogen, causing multi-organ birth defects in humans. Endogenous RA levels must therefore be tightly controlled in the developing embryo. In order to understand the RA function and regulation at the genomic level, we used a microarray approach to identify genes that function as negative feedback regulators of retinoic acid signaling. To that end, we treated embryos with different chemicals: DMSO as control, AGN193019 as RA antagonist at high concentration 10uM and low concentration 1uM, as well as 0.33uM RA. Each treatment has four biological replicates. We screened for genes expressed in early somite-stage embryos that respond oppositely to treatment with RA versus RA antagonists, and validated them by whole-mount RNA in situ hybridization.

Project description:Extracellular vesicles (EVs) are present in all body fluids. Shed by cells, their molecular make-up reflects that of their cell of origin and/or tissue pathological situation. Our working hypothesis was that analyzing the protein composition, protein abundance, and functional clustering of EVs released by peritoneal exudate cells (PECs) in the pristane experimental lupus model would allow us to identify predictive or diagnostic biomarkers that might discriminate the autoimmunity process in lupus from inflammatory reactions and/or normal physiological processes. Three pools of PE-EVs were isolated from pristane-treated mice (WT versus Cd38-/- mice) by qEV size exclusion column methodology (F5-12, F5-10 and F11-12). Protein extracts were analyzed by LC-MS/MS. Protein identification was performed with ProteinScape, and MASCOT data searching using Swiss-Prot database. For relative quantification the emPAI-based method was used. The functional enrichment analysis was based on the latest publicly available data from multiple annotation and ontology resources that can be automatically accessed through ClueGO + CluePedia apps within Cytoscape environment. STRING app and EnrichR tools were also used. Gene Ontology (GO) and signaling pathways enrichment analyses of F5-10 and F11-12 PE-EVs via ClueGO analyses showed that the proteins clustered in functionally distinct GO terms and signaling pathways. Moreover, the predominance of given GO terms in PE-EVs seemed to vary with the extent of the inflammatory/autoimmune reaction to pristane. Compared with the protein content and protein abundance in PECs (mainly Ly6Chi inflammatory monocytes and neutrophils), PE-EVs showed an enrichment in neutrophil-associated functions, in particular in PE-EVs from Cd38-/- mice.
