Autoimmune triggers induced exacerbated autoimmunity in Sh2b3E372K
mice. (A and B) Serum ANAs (A; +/+: n = 14, E372K/+: n = 4, E372K/E372K: n = 13) and anti-DNA IgG (B; +/+: n = 15, E372K/+: n = 8, E372K/E372K: n = 15) determined by ELISA. One-way ANOVA was used for statistical analyses. Results are pooled from two to four separate mouse cohorts and representative to two independent experiments. (C) Experimental plan of pristane-induced lupus-like autoimmune model in Sh2b3E372K mice. 14-wk-old female Sh2b3E372K mice were bled 1 day before the IP injection of 0.25-ml pristane or PBS (control) and later 2-, 10-, and 20-wk after injection and sacrificed 24-wk after injection for spleen and kidney analysis. (D–I) Levels of serum anti-DNA IgG in pristane-treated mice at 0 (D), 10 (E), and 20 (F) weeks after treatment, and PBS-treated mice at 0 (G), 10 (H), and 20 (I) weeks after treatment. Means are shown as bars in all dot plots. Data were pooled from two independent experiments, +/+: n = 8, E372K: n = 5, E372K/E372K: n = 11. Statistical analyses performed using lmer ANOVA; *: P < 0.05.
