Figure 2From: Serum level of soluble CX3CL1/fractalkine is elevated in patients with polymyositis and dermatomyositis, which is correlated with disease activityCX3CR1 expressions in affected muscle of patients with polymyositis. The muscle tissues of polymyositis (PM) patients were double-stained with CD4, CD8, or CD68, as well as CX3CR1, and were analyzed with fluorescent microscopy: (A) CX3CR1, (B) CD4, (C) merged (A) and (B), (D) CX3CR1, (E) CD8, (F) merged (D) and (E), (G) CX3CR1, (H) CD68, and (I) merged (G) and (H). Arrows indicate double-positive cells. Original magnification, ×400.Back to article page
