Effect of a TRAIL-neutralizing antibody against TRAIL-induced neutrophil apoptosis in SLE patients with neutropenia. The TRAIL-neutralizing antibody significantly inhibited TRAIL-induced neutrophil apoptosis in a dose-dependent manner (*P < .001, Bonferroni/Dunn with one-way factorial ANOVA). (A) Representative data from 8 individual experiments. (B) Data were shown with mean + standard deviation (n = 8 in each group).
