Effect of the C5aR antagonist AcF[OPdChaWR] on
E coli–induced oxidative burst in granulocytes.The left panel shows dose-response effect of the C5aR antagonist using 1 × 108E coli per milliliter (1 representative of 5 experiments is shown). The right panel shows the effect of 2 μM C5aR antagonist on E coli–induced oxidative burst by reducing the concentration ofE coli (median and range of triplicate). The oxidative burst is given as median fluorescence intensity (MFI). ▵ indicates baseline value (T0); ▴, whole blood incubated 10 minutes withE coli (1 × 108 bacteria per milliliter); ●, E coli plus C5aR antagonist; ○, E coli plus control peptide; and ■, E coli plus PBS.
