The 26 kDa form of splenic TNF-α was not significantly elevated in LPS-challenged SLE mice compared to their counterparts (5.1 × 106 ± 1.8 × 105 vs. 3.0 × 106 ± 8.6 × 105 intensity units, p = 0.187), however, was increased in LPS-challenged controls compared to vehicle-treated controls (4.5 × 106 ± 6.5 × 105 vs. 1.1 × 106 ± 2.2 × 105 intensity units, p = 0.043). This evidence concerns the gene TNF and systemic lupus erythematosus.
