Brain TNF-α (both 26 and 51 kDa isoforms) did not differ between SLE and control mice (1.2 × 106 ± 6.1 × 105 vs. 3.4 × 105 ± 7.6 × 104 intensity units, p = 0.754 for 26 kDa; 6.4 × 105 ± 2.4 × 105 vs. 3.3 × 104 ± 7.9 × 103 intensity units, p = 0.766 for 51 kDa) (Figure 5B,C). Here, TNF is linked to systemic lupus erythematosus.
