Interestingly, LPR mice also expressed autoantibodies found in dermatomyositis patients (TIF1γ, Jo1, PL-7, SAE1/SAE2, MDA5, NXP2, mi-2, PM/Scl100) who also demonstrate photosensitivity (48), and some of these (Jo-1,NXP2, PM/Scl100) were also reduced with MLD (Figure 4, C and D). This evidence concerns the gene IFIH1 and dermatomyositis.
