In addition, we further analyzed the association between autoantibodies and the expression of PPAR-γ in SLE circulating CD14+ monocytes and found a higher mRNA level of PPAR-γ in the SLE patients with positive anti-dsDNA Abs compared to those with negative anti-dsDNA Abs (Figure 2E). This evidence concerns the gene CD14 and systemic lupus erythematosus.
