In consistent, serum expression of Treg-related TGF-β and IL-10 was enhanced by 121.67% [34.262 (28.016, 45.254) vs. 16.973 (12.117, 19.643), P < 0.001] and 8.83% [12.855 (12.210, 13.620) vs. 12.000 (11.155, 12.860), P = 0.0029] in MMD patients compared with control. This evidence concerns the gene IL10 and multiminicore myopathy.
