Thrombus formation in whole blood. ( A ) Thrombus formation upon treatment with 600 ng/mL pneumolysin (Ply) or pneumolysin preincubated with IVIG or trimodulin. A quantitative assessment of thrombus formation was performed by analyzing the area of the collagen-coated microchannel slide that was covered by thrombi. Curves represent the mean of platelets of three donors. As a control, whole blood was incubated with PBS only. ( B ) Thrombus formation upon treatment with immunoglobulin preparations (without pneumolysin) to investigate their effects alone on the thrombus formation. A quantitative assessment of thrombus formation was performed by analyzing the area covered. Curves represent the mean of platelets of three donors. As a control, whole blood was incubated with PBS only. IVIG, intravenous immunoglobulin; PBS, phosphate-buffered saline.
