| Research Abstract |
In this study, the effect of infection with periodontopathic bacteria on the lipid metabolism was analyzed. Periodontitis patients demonstrated the shift of serum lipid profile towards atherogenic with concomitant elevation of serum PCSK9 level. In mouse experimental periodontitis model induced by the infection with Porphyromonas gingivalis, various lipid metabolism-related genes including PCSK9 demonstrated changes towards proatherogenic. Serum HDL-cholesterol decreased in P. gingivalis-infected mice. These results suggest that infection with periodontopathic bacteria promotes atherosclerosis by suppression of cholesterol efflux and increased expression of LDL receptor in the liver.
