CD8A and Miyoshi myopathy: Individuals from all cohorts had similar levels of CD3+CD8+TCRγδ+ cells (Figure 6A, left graph), but the expression of CD107a was mostly reduced in these cells of individuals with MM (3.0-fold; p = 0.0158) before vaccination, in comparison with healthy donors (Figure 6A, right graph), although it was significantly increased after one-dose vaccination (2.1-fold; p = 0.0374).
