Project description:This SuperSeries is composed of the following subset Series: GSE18023: Mice with FIA develop anti-native and anti-in vitro citrullinated fibrinogen antibodies GSE18024: FIA plasma induces arthritis in naïve mice GSE18025: Fibrinogen-reactive T cells transfer disease to naïve mice Refer to individual Series
Project description:Splenocytes harvested from mice with FIA were cultured in vitro and stimulated with 0.01 mg/ml fibrinogen for 3 days. Enriched T cells were transferred into 6-week-old naïve SJL mice, which developed visible signs of arthritis within 2 weeks. Synovial array profiling of plasma from the arthritic recipient mice demonstrated autoreactive B cell responses against peptides representing native fibrinogen, and further spreading of the responses to target collagen type V, cartilage gp39, and citrullinated vimentin. Custom-spotted protein slides were with plasma samples from individual mice. Four slides were probed with plasma derived from naïve mice and five slides were probed with plasma derived from mice injected with FIA T cells.
Project description:Synovial antigen arrays were probed with 1:150 dilutions of plasma derived from SJL mice immunized with fibrinogen emulsified in CFA or with CFA alone. Autoantibody binding was detected with a Cy3-conjugated goat-anti-mouse IgG/M secondary antibody. SAM was applied to identify antigens with statistically significant differences in array reactivity between FIA and CFA control plasma (q < 0.01) obtained from mice before boosting. The SAM hits were subjected to hierarchical cluster analysis and are displayed as a heatmap. Synovial array profiling of FIA plasma demonstrated autoreactive B-cell responses against peptides representing native fibrinogen, and B-cell epitope spreading resulting in additional targeting of citrullinated fibrinogen in the samples obtained before boosting. Custom-spotted protein slides were probed with plasma samples from individual mice. Four slides were probed with plasma derived from mice immunized with CFA and six slides were probed with plasma derived from mice immunized with fibrinogen emulsified in CFA.

Project description:Plasma collected from mice with FIA were pooled, and 0.3 ml was injected intravenously into 6-week-old naïve SJL mice on days 0 and 2. Synovial antigen array profiling of plasma from the arthritic recipient mice demonstrated autoreactive B-cell responses against peptides representing native fibrinogen and citrullinated fibrinogen, and further epitope spreading resulting in additional targeting of fibronectin, collagen type V, cartilage gp39, and clusterin. Custom-spotted protein slides were probed with plasma samples from individual mice. Four slides were probed with plasma derived from naïve mice and four slides were probed with plasma derived from mice injected with FIA plasma.
