Further the counts of CD3+CD4+ T cells, CD3+CD8+T cells, CD5+CD19+ B cells, and NK cells were much lower, whereas the proportion of CD5-CD19+ B cells was higher in MDA5+ DM patients with RP-ILD than in ASS patients (all p values < 0.05) (Table 3). The gene discussed is CD19; the disease is dermatomyositis.
