FIG. 5.

Infection of HUVEC with a P. gingivalis fimA mutant does not stimulate P-selectin (A) and E-selectin (B) expression. HUVEC were infected with P. gingivalis strains 381 (wildtype [wt]) and DPG3 (fimA). Cells harvested at 2 h postinfection and processed for FACS analysis (upper panels) or for confocal microscopy (lower panels). Values are the means ± standard errors of the means for three independent experiments. Statistical significance was assigned when the P value was <0.05 (*) compared to uninfected HUVEC.
