Functional reactivity against IgG as part of surface-bound collagen type II autoantibody (anti-CII) immune complex and polyclonal IgG. Amounts and functional reactivity against IgG as part of surface-bound collagen type II autoantibody (anti-CII) immune complex and polyclonal IgG directly coated to identical enzyme-linked immunosorbent assay (ELISA) plates. (a) ELISA reactivity of IgG against type II collagen (CII) aligned to known concentrations of directly coated IgG; these anti-CII levels (μg/ml) were thereafter used in the comparisons below. (b) Peripheral blood mononuclear cell-derived tumor necrosis factor alpha (ΤΝFα). (c), (d) Polymorphonuclear granulocyte expression of CD66b and of CD16 respectively were compared for different concentrations of anti-CII and polyclonal IgG. Panels depict one representative result out of two to four experiments performed for each comparison. MFI, mean fluorescence intensity; OD, optical density.
