Between normal and DCM samples, we observed abnormal regulatory levels exhibited by gamma delta T cells, activated CD8 T cells, activated dendritic cells, CD56 bright natural killer cells, eosinophils, activated CD4 T cells, immature dendritic cells, MDSC, macrophages, mast cells, natural killer T cells, neutrophils, plasmacytoid dendritic cells, regulatory T cells, T follicular helper cells, type 1 T helper cells, type 17 T helper cells, and type 2 T helper cells (Figure 8A). Here, CD4 is linked to familial dilated cardiomyopathy.
