Comparison of TRAIL receptor expression on neutrophils of SLE patients with neutropenia before and after therapy. TRAIL receptor 3 expression levels significantly increased after treatment (**P < .05, Bonferroni/Dunn with a one-way factorial ANOVA). (A) Representative data from 8 individual experiments. Dotted line indicates IgG control intensity; solid line indicates TRAIL receptor expression intensity. (B) Data are shown with mean + standard deviations (n = 8 in each group).
