Furthermore, IFNγ and TNF co-producing bifunctional MAIT cell frequency was significantly elevated in the ME-SA group (56.1%) compared to the ME-MM group (48.4%) (p = 0.048) (Fig. 6e), whereas the proportion of IFNγ- TNF- double negative MAITs was reduced (p = 0.001). Here, TNF is linked to Miyoshi myopathy.
