Formation of platelet-leukocyte complexes in response to stimulation with ADP or oral bacteria (Aggregatibacter actinomycetemcomitans [Aa], Porphyromonas gingivalis [Pg], Tannerella forsythia [Tf], Streptococcus sanguis [Ss] and Streptococcus mutans [Sm]). The number of CD61-positive (equivalent to platelet-conjugated) leukocytes (PLC) was recorded as a percentage of the total population. Data were plotted as fold change [% platelet-bound cells after stimulation/% platelet-bound cells in unstimulated sample in buffer] representing the change in number of complexes formed in response to stimulation with ADP or oral bacteria. Data are presented as means ± standard error of the mean (N = 25). The addition of stimuli induced formation of complexes when analyzed within each timepoint (P < 0.001 in repeated measures ANOVA). The comparisons between timepoints were analyzed by paired T- test (*P < 0.05 baseline vs. recall)
