Comparing the two groups, we found people with ME-SA had an elevated frequency of CD69 expression on T cell subsets, including CD4+ and CD8+ T cells and MAITs cells, compared to people with ME-MM (p = 0.019 in CD4+ T cell, p = 0.010 in CD8+ T cells, p = 0.023 in MAIT cells) (Fig. 5b). Here, CD4 is linked to Miyoshi myopathy.
