FIG. 1.

P. gingivalis infection stimulates ICAM-1 and VCAM-1 expression in HUVEC. P. gingivalis strain A7436 cultures were added to a HUVEC monolayer at an MOI of 100:1 and incubated at 37°C for 2 h. Cells were then collected and processed for FACS analysis for surface-associated ICAM-1 and VCAM-1. Values are the means ± standard errors of the means for three independent experiments. Statistical significance was assigned when the P value was <0.05 (*) or <0.001 (**) compared to uninfected HUVEC (control).
