Figure 6From: Selective delivery of interleukine-1 receptor antagonist to inflamed joint by albumin fusionThe uptake kinetics of131I-labeled fusion protein and131I-labeled IL-1ra in the liver (A), kidney (B), spleen (C), and lung (D) of mice with (n = 5) and without CIA (n = 5). Data are expressed as mean ± SEM. * = p < 0.05 and ** = p < 0.01 versus uptake rates of 131I-labeled IL-1ra in liver, kidney, spleen, and lung of arthritic mice or healthy mice.Back to article page
