Gallic Acid Attenuates Platelet Activation and Platelet-Leukocyte Aggregation: Involving Pathways of Akt and GSK3β

Figure 2

Flow cytometric analysis of the effects of gallic acid on platelet-leukocyte aggregates (PLAs) after stimulation with ADP or U46619. Quantitative results of the influence of gallic acid (100 μM, 500 μM) on PLA induced by (a) ADP (2 μM) or (b) U46619 (2 μM) by means of the mean fluorescence intensity of CD42a. Platelet-monocyte (open bars) and platelet-granulocyte (filled bars) aggregates were both inhibited by gallic acid in a concentration-dependent manner. Results are presented as mean ± SEM, . *,** versus control samples stimulated with ADP or U46619. GA: gallic acid.
