英文摘要
We analyzed a fate of Porphyromonas gingivalis, a periodontal pathogen, with human aortic endothelial cells by live-imaging. We detected the bacteria within the cells for 6-8 hs, but failed to find them for 18-24 hs, indicating that the bacteria is probably transported to the lysosomes.Futhermore, we performed live-imaging of P. gingivalis using mice. We found that the bacteria attached on blood vessels of bifurcation area and thin vessels. In ApoE-deficient mice, which is a model for arterial sclerosis, the attachment rate of the bacteria was increased. These results indicate that cholesterol in the blood probably interacts with P. gingivalis during endocytosis.
