In CyTOF cohort, the expression levels of CCR10, CXCR3, CX3CR1, CD45RO, CD11b, CD11c, CD27, CD62L, HLA‐DR, p‐STAT3, and ERK were higher in MMD patients; the levels of CCR6, CXCR4, PD‐1, MYD88, NFκB, and AKT were lower than in the HC group in both CD4+T and CD8+T cells (Figure S11B,C). This evidence concerns the gene SELL and multiminicore myopathy.
