Compared to the HC group, we found that the percentage of CD3 + T cells was lower (medium 45.1%, interquartile range (IQR) 34.5%-54.2% versus HC [60.8%, IQR 54.8%-66.4%]) (p < 0.001), while the percentage of CD14 + monocytes was higher (11.0%, IQR 8.0%-18.2% versus HC [5.7%, IQR 4.1%-7.8%]) (p < 0.001) in the peripheral blood of IIM patients (Fig. 1A). Here, CD14 is linked to acquired idiopathic inflammatory myopathy.
