TNF and systemic lupus erythematosus: Splenic TNF-α (26 and 51 kDa) did not differ between vehicle-treated SLE and control mice (3.0 × 106 ± 8.6 × 105 vs. 1.1 × 106 ± 2.2 × 105 intensity units, p = 0.231 for 26 kDa; 2.4 × 106 ± 2.1 × 105 vs. 1.6 × 106 ± 3.4 × 105 intensity units, p = 0.076 for 51 kDa) (Figure 5E,F).
