Figure 3From: Serum level of soluble CX3CL1/fractalkine is elevated in patients with polymyositis and dermatomyositis, which is correlated with disease activityCX3CL1 and CX3CR1 expressions in lung with ILD in polymyositis patients. Lung specimens from (A, B, G, H) controls and (C to F and I to L) polymyositis (PM) patients with ILD were stained with anti-CX3CL1 mAb (A, C, E), anti-CX3CR1 antibody (G, I, K), or isotype-matched control antibodies (B, D, F, H, J, L). Arrows indicate the positive infiltrated mononuclear cells (I), alveolar macrophages (M), vascular endothelial cells (V), and epithelial cells (E). Original magnification, ×400.Back to article page
