As MAITs cells act as innate-like T cells in response to microbial infection, we performed a correlation analysis between the frequency of NK cells, another innate immune cell type, and MAITs to determine whether these innate immune cells’ appearance together would affect the first line of defence in microbial infection, and found that the frequency of CD28+ MAITs was moderately correlated with the frequency of NK cells (r = 0.569, p < 0.0001) in ME-MM. The gene discussed is CD28; the disease is Miyoshi myopathy.
