In patients with DM-related encephalopathy and with DM in remission, the percentage of naïve CD4+ T cells was increased in comparison to healthy controls (HC) (56.6% [26.8–76.5] vs. 6.43% [4.52–8.8] p = 0.011), and (43.8% [35.8–43.8] vs. 6.43% [4.52–8.8] p = 0.021) respectively (Figure 5c). Here, CD4 is linked to dermatomyositis.
