Grading of numbers of cells positive for immunohistochemical markers of DCs (DC-LAMP for mature DCs, BDCA-1 for myeloid DCs, and BDCA-2 for plasmacytoid DCs) and for the type I IFN–induced gene product, MxA, in muscle and skin tissue sections. Samples from patients with juvenile dermatomyositis were compared with those from pediatric controls. The y-axis shows the semiquantitative scores of DC markers for DC-LAMP, BDCA-1, and BDCA-2 and for type I IFN signaling with MxA protein for muscle (A) and skin (B). Horizontal lines represent the median; bars represent the interquartile range. P values were calculated using the Mann-Whitney U test. See Figure 3 for definitions.
