Project description:NZB/WF1 female mice spontaneously develop autoimmune lupus nephritis. Expression profiling of kidney tissue from (a) 12 week NZB/W F1 female mice defined as asymptomatic for lupus nephritis, (b) 36 and 42 week NZB/W F1 female mice defined as diseased/symptomatic for lupus nephritis and (c) 36 and 42 week NZB/W F1 female mice that are diseased/symptomatic for lupus nephritis and treated with Sirolimus was carried out. The goal of the study was to identify genes associated with lupus nephritis and modulated by Sirolimus, an inhibitor of mTOR. In addition, lupus nephritis genes resistant to Sirolimus therapy were also identfied This series of samples comprises of kidney tissue from (a) 12 week old NZB/W F1 female mice defined as asymptomatic for lupus nephritis (N=4), (b) 36 (N=3) and 42 week (N=3) old NZB/W F1 female mice defined as diseased/symptomatic for lupus nephritis and (c) 36 (N=3)and 42 (N=3) week old NZB/W F1 female mice that are asymptomatic for lupus nephritis on treatment with Sirolimus

Project description:Transcriptomic analysis of gene expression of splenocytes from 16-week-old female NZB/NZW F1 (BWF1) mice, which are prone to lupus, and comparison to gene expression of splenocytes from male BWF1 and female BALB/c mice, which are not prone to lupus. Results provide insight into the differences in immunological activities that make female BWF1 mice more susceptible to lupus.
Project description:The purpose of this study was to examine the effect of aldosterone receptor blockade on the immunopathogenesis and progression of nephritis in the (NZBxNZW) F1 murine lupus model. Female NZB/W F1 mice (11 weeks old) were treated daily with 25 or 50 mg/kg of oral spironolactone or vehicle. Proteinuria, renal function and serum autoantibody levels were monitored. Renal histopathology, immune complex deposition, and immunohistochemistry were analyzed at various time points. Targeted microarray analysis was performed on renal tissue, with subsequent real time PCR analysis of several differentially expressed genes. Keywords: treatment study
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: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:We characterized the longitudinal gene expression profiles of kidneys from a lupus model nephtiris: NZB X NZW F1 (BWF1) mice treated with IFN-alpha using adenovirus delivery. 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.

Female NZB/W F1 mice (11 weeks old) were treated daily with 25 or 50 mg/kg of oral spironolactone or vehicle. Proteinuria, renal function and serum autoantibody levels were monitored. Renal histopathology, immune complex deposition, and immunohistochemistry were analyzed at various time points. Targeted microarray analysis was performed on renal tissue, with subsequent real time PCR analysis of several differentially expressed genes. At 36 weeks of age, 8 mice from each treatment group (vehicle, 25 mg/kg/d spironolactone and 50 mg/kg/d spironolactone) were anesthetized and perfused with cold saline; then one kidney per mouse was removed , homogenized in Tripure, and frozen at -80 until RNA extraction. RNA was extracted using Tripure and a Qiagen RNEasy Minikit. RNA was pooled equally by weight within each treatment group and frozen at -80. Subsequently, the three batches of pooled RNA were processed for microarray analysis.
Project description:Transcriptomes of splenocytes from 16-week-old lupus-prone female NZB/NZW F1 mice and non-lupus-prone male NZB/NZW F1 and female BALB/c mice
Project description:We've recently shown that we can accelerate disease in a model of SLE (the NZB/W F1 model) using an anti-Ox40 mAb treatment regimen. The disease acceleration is rapid (within 2 weeks) but its unclear, mechanistically, how OX40 functions to promote disease. To that end we want to perform RNASeq on the sorted OX40-expressing CD4 T cells during treatment to understand how they function in response to OX40 signaling in vivo
