Methods HUVECs infected with different fimA genotypes were divided into the fimA type I stimulation group, fimA type II stimu⁃ lation group, fimA type IV stimulation group. In addition, a positive control group (E. coli LPS stimulation) and negative control group (cell culture medium only) were included. Cell proliferation was detected by MTT assay, and cell apopto⁃ sis was detected by flow cytometry. IL⁃1β, IL⁃6, TNF⁃ α levels in the supernatant of HUVECs after P. g stimulation were assessed by ELISA at 2 h, 6 h and 24 h. Results HUVECs were infected by P. g with fimA type I, fimA type II and LPS for 24 h. Cell proliferation was inhibited compared with the negative control group (P < 0.05), but there was no significant difference in the apoptosis rate between P. g infection and the negative control group. IL⁃1β levels in cell culture supernatants were higher at 2th than 6 and 24 h after stimulation of HUVECs with different fimA genotypes, while the IL-6 levels were higher at 24 h than the other time, while the TNF-α levels were no significant difference at every time. After fimA type II and IV P. g infection, IL⁃1β, IL⁃6, and TNF⁃α levels were increased compared with fimA type I P. g (P < 0.05). Conclusion Different P. g fimA genotypes have different effects on stimulating HUVECs to in⁃ duce dysfunction. Here, fimA type II and IV P. g exhibit a strong ability to upregulate the secretion of IL⁃1β, IL⁃6 and TNF⁃alpha.http://www.kqjbfz.com/EN/10.12016/j.issn.2096-1456.2019.06.005Porphyromonas gingivalis,Interleukin,Tumor necrosis factor⁃α,Atherosclerosis,Periodontosis, |

Objective To study the effects of Porphyromonas gingivalis (P. g) infection with I, II and IV fimA genotypes
on the expression of IL⁃ 1beta, IL⁃6 and TNF⁃alpha in human umbilical vein endothelial cells (HUVECs). Methods
HUVECs infected with different fimA genotypes were divided into the fimA type I stimulation group, fimA type II stimu⁃
lation group, fimA type IV stimulation group. In addition, a positive control group (E. coli LPS stimulation) and negative
control group (cell culture medium only) were included. Cell proliferation was detected by MTT assay, and cell apopto⁃
sis was detected by flow cytometry. IL⁃1β, IL⁃6, TNF⁃ α levels in the supernatant of HUVECs after P. g stimulation
were assessed by ELISA at 2 h, 6 h and 24 h. Results HUVECs were infected by P. g with fimA type I, fimA type II
and LPS for 24 h. Cell proliferation was inhibited compared with the negative control group (P < 0.05), but there was no significant difference in the apoptosis rate between P. g infection and the negative control group. IL⁃1β levels in cell
culture supernatants were higher at 2th than 6 and 24 h after stimulation of HUVECs with different fimA genotypes,
while the IL-6 levels were higher at 24 h than the other time, while the TNF-α levels were no significant difference at
every time. After fimA type II and IV P. g infection, IL⁃1β, IL⁃6, and TNF⁃α levels were increased compared with fimA
type I P. g (P < 0.05). Conclusion Different P. g fimA genotypes have different effects on stimulating HUVECs to in⁃
duce dysfunction. Here, fimA type II and IV P. g exhibit a strong ability to upregulate the secretion of IL⁃1β, IL⁃6 and
TNF⁃alpha. |
