Figure 2. Gingerols suppress ROS.

Human neutrophils were treated with various stimuli in the presence of different gingerol analogs for 1 hour. Hydrogen peroxide formation was measured by a colorimetric assay. Mean and SEM are presented for n = 3 independent experiments; *P < 0.05, ****P < 0.0001 as compared with the LPS-alone group (A), PMA-alone group (B), RNP ICs–alone group (C), or APS IgG–alone group (D) by 1-way ANOVA corrected with Dunnett’s test.
