摘要/Abstract

摘要：

目的: 探讨牙龈卟啉单胞菌(Porphyromonas gingivalis,P. gingivalis)引起的炎症和氧化应激反应对动脉粥样硬化的影响及作用机制。方法: 采用8周龄载脂蛋白e基因敲除(ApoE knockout,ApoE-/-)小鼠建立动脉粥样硬化动物模型,将小鼠随机分为两组:(1)磷酸盐缓冲液(phosphate buffered saline,PBS)健康对照组:8只ApoE-/-小鼠,普通饮食+PBS鼠尾静脉注射;(2)P. gingivalis感染组:8只ApoE-/-小鼠,普通饮食+P. gingivalis鼠尾静脉注射。1周3次,隔天1次,共10次。4周后处死,取心脏组织进行油红O染色,血清进行酶联免疫吸附测定(enzyme-linked immunosorbent assay,ELISA),主动脉进行实时荧光定量PCR以及Western blot检测。结果: P. gingivalis 感染组较PBS健康对照组可以显著加重ApoE-/-小鼠动脉粥样硬化斑块的形成,增加血清中炎症介质,如白细胞介素(interleukin,IL)-1β、IL-6和肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)以及氧化应激介质8-羟脱氧鸟苷(8-hydroxy-2-deoxyguanosine,8-OHDG)表达,增加主动脉组织中IL-1β、IL-6、TNF-α、NADPH 氧化酶(NADPH oxidase,NOX)-2和NOX-4基因的mRNA水平。P. gingivalis感染后在主动脉组织中观察到核转录因子-κB(nuclear factor-kappa B,NF-κB)表达有增高趋势。结论: P.gingivalis感染会加速ApoE-/-小鼠动脉粥样硬化进程,诱导氧化应激和炎症反应;NF-κB信号通路可能是P. gingivalis加速动脉粥样硬化形成的重要作用机制。

Abstract:

Objective: Studies have indicated that periodontal pathogen Porphyromonas gingivalis (P. gingivalis) infection may contributed to accelerate the development of atherosclerosis. The aim of this study was to investigate the effect of inflammation, oxidative stress and the mechanism on atherosclerosis in apolipoprotein-E knockout (ApoE-/-) mice with P. gingivalis infection. Methods: Eight-week-old male ApoE-/- mice (C57BL/6) were maintained under specific pathogen-free conditions and fed regular chow and sterile water after 1 weeks of housing. The animals were randomly divided into two groups: (a) ApoE-/- + PBS (n=8); (b) ApoE-/- + P.gingivalis strain FDC381 (n=8). Both of the groups received intravenous injections 3 times per week for 4 weeks since 8 weeks of age. The sham control group received injections with phosphate buffered saline only, while the P. gingivalis-challenged group with P.gingivalis strain FDC381at the same time. After 4 weeks, oxidative stress mediators and inflammation cytokines were analyzed by oil red O in heart, Enzyme linked immunosorbent assay (ELISA) in serum, quantitative real-time PCR and Western blot in aorta. Results: In our study, we found accelerated development of atherosclerosis and plaque formation in aorta with oil red O staining, increased oxidative stress markers [8-hydroxy-2-deoxyguanosine (8-OHdG), NADPH oxidase (NOX)-2 and NOX-4], as well as increased inflammation cytokines [interleukin (IL)-1β, IL-6 and tumor necrosis factor-α (TNF-α)] in the serum and aorta of the P. gingivalis-infected ApoE-/- mice. Compared with the control group, there was a significant increase protein level of nuclear factor-kappa B (NF-κB) in aorta after P. gingivalis infection. Conclusion: Our results suggest that chronic intravenous infection of P. gingivalis in ApoE-/- mice could accelerate the development of atherosclerosis by disturbing the lipid profile and inducing oxidative stress and inflammation. The NF-κB signaling pathway might play a potential role in the P. gingivalis-accelerated atherogenesis.
