![Phenotypic Characterization of Collagen Induced Arthritis in DBA/1J Mice. DBA/1J mice were immunized with bovine type II collagen (N = 11–55; arthritic: n = 6–18; non-arthritic: n = 5–37) or PBS (N = 4–14).

Figure Legend Snippet: Splenic T Cell Proliferation Following Stimulation with Type II Collagen Protein. Splenocytes isolated at day 49 post primary immunization from DBA/1J mice immunized with bovine type II collagen (bCII) (arthritic: N = 8; non-arthritic: N = 7) or PBS (N = 10) were cultured in media alone or 80 μg/mL bCII protein. Following 72 h incubation, A) CD4 + and B) CD8 + T cell proliferation following stimulation with bCII was measured by flow cytometry and is shown as a mean (±SD) stimulation index, with data points representing individual mice. Stimulation indices greater than 1.6 (dashed line) were considered a positive response. Statistical analysis was performed using one-way ANOVA with Tukey's multiple comparisons test, and the resulting p-values were p = 0.0054 and p = 0.0987 respectively, with p-values for pairwise comparisons indicated on the graphs. ns: not significant.
Techniques Used: Isolation, Cell Culture, Incubation, Flow Cytometry
Figure Legend Snippet: RA-Specific Serum IgG Antibodies in DBA/1J Mice. Sera were collected biweekly from DBA/1J mice immunized with bovine type II collagen (bCII) (arthritic: N = 9–18; non-arthritic: N = 17–37), or PBS (N = 14) and tested via indirect ELISA for A) anti-CitP, and B) anti-HomoCitP IgG antibodies. Graphs show the median [IQR] for each group, with a cut-off indicating the limit of detection (dashed line). Statistical analysis was performed using a mixed effects model with the Geisser-Greenhouse correction and Tukey's multiple comparisons test. The resulting p-values are indicated on the graphs.
