have demonstrated that the levels of regulatory T cells (Tregs), T helper 17 (Th17), and some of their related inflammatory cytokines—including Treg‐related TGF‐β and interleukin (IL)‐10 and Th17‐related IL‐17, TNF‐α, IL‐6, and IL‐23—are significantly elevated in patients with MMD compared with those with atherothrombotic stroke and healthy controls. The gene discussed is TGFB1; the disease is multiminicore myopathy.
