Mouse models of SLE have proved so,12 and the improvement goes together with a lower atherogenic risk due to reduced expression of IL-12 and IFN-γ, reduced NF-κB activation, and the induction of T regulatory cells.13 It is likely that a tailored diet, possibly based on the genetic study of the affected individual, may improve through TLR7, the outcome of lupus disease. Here, TLR7 is linked to systemic lupus erythematosus.
