Abstract: Atherosclerosis is an important morbidity and mortality cause of cardiovascular diseases such as coronary heart disease and stroke. It has been confirmed that periodontal disease is independently related to atherosclerosis. Fusobacterium nucleatum is a common pathogenic bacterium in the subgingival plaque of periodontitis. When periodontal tissue is in a state of inflammation, Fusobacterium nucleatum can enter the blood circulation through damaged capillaries, and then adhere to endothelial cells, destroying endothelial integrity and causing endothelial dysfunction. At the same time, Fusobacterium nucleatum and its heat shock protein can activate pro-inflammatory factors, enhance inflammatory response, lead to disorder of lipid metabolism, and eventually lead to the formation of atherosclerotic plaque. Therefore, this article reviews the possible molecular mechanisms of the interaction between Fusobacterium nucleatum and atherosclerosis.

Key words: atherosclerosis, Fusobacterium nucleatum, FadA, GroEL, inflammation, dyslipidemia
