Figure 1From: Anti-type II collagen immune complex-induced granulocyte reactivity is associated with joint erosions in RA patients with anti-collagen antibodies Granulocyte expression of CD11b, CD66b, CD16, and CD32. Granulocyte expression of (a) CD11b, (b) CD66b, (c) CD16, and (d) CD32 after 18 hours of stimulation with surface-bound collagen type II autoantibody (anti-CII) immune complex (IC) prepared with a high-level anti-CII serum or with normal human serum. Eight healthy donors provided the cells. Horizontal bars, median values. Statistical comparisons were made with the paired Wilcoxon signed-rank test. CII, collagen type II; MFI, mean fluorescence intensity; NHS, normal human serum.Back to article page
