FIG. 2.

zVAD-fmk partially abolishes P. gingivalis-induced early PS exposure, as determined by Annexin-V-PI staining and analyzed by flow cytometry. GECs were either uninfected (control) or infected for 30 min or 2 h in the absence or presence of 40 μM zVAD-fmk. The bars show the percentages of GECs stained for PS externalization under the different conditions. Data are expressed as the means from at least two separate experiments, and the values represent the means and standard deviations of separate measurements.
