In both, cDC1-specific genes appeared to have stronger correlations with inflammatory markers (including TBX21, and, in PM-CD8, KLRG1) than in IBM patients, and, in PM-Mito patients, mregDC-specific genes also appeared to have stronger correlations with inflammatory markers than in IBM patients (Extended Data Figure 9B–C). This evidence concerns the gene KLRG1 and inclusion body myositis.
