Fig. 2. Neutrophil activation.
Neutrophil activation was assessed by flow cytometry as the % of Ly6G positive cells expressing myeloperoxidase (MPO) and CD18 on the membrane surface above a threshold concentration present on control cells. Mouse groups and data are as described in Fig. 1. *P < 0.001 vs. control (ANOVA) and +P < 0.001 for those injected with F-positive MPs versus F-negative MPs (t test).
