CD8A and Miyoshi myopathy: In addition, the levels of cytokine production and degranulation were similar in MM patients with detectable spike-specific CD8+ T cells compared to HCs (IFNγ: 0.40 in MM patients vs. 0.41 in HCs (p = 0.7459); TNF: 0.35 in MM patients vs. 0.35 in HCs (p = 0.9445); CD107a: 0.28 in MM patients vs. 0.57 in HCs (p = 0.2275)) (Figure 3F).
