PPARG and systemic lupus erythematosus: PPARγ mRNA level in macrophages exposed to 10% plasma obtained from SLE subjects post-placebo treatment and 10% plasma obtained from SLE subjects post-atorvastatin-treatment showed no change at 1.13 (95% CI (0.67 to 1.90)) and 0.99 (95% CI (0.70 to 1.42), Finteraction (1, 29) = 0.206, p = 0.65; Figure 2) versus cells exposed to pre-placebo- or pre-atorvastatin plasma.
