Effect of the indicated additions of LPS on the phagocytosis of (A) W6/32-opsonized, (B) nonopsonized, and (C) W6/32 F(ab′)2 fragment-bound CM-G–labeled human platelets by THP-1 cells. The data are presented as the mean phagocytic index (± SD) from 10 (A-B) and 5 (C) independent experiments and were calculated by the following formula: median channel FL1 fluorescence at 37°C/median channel FL1 fluorescence at 4°C. Statistical significance in panel A by a 1-way ANOVA was P < .001.
