expresses a broad array of virulence factors that enable it to play a central role in the etiopathogenesis of periodontitis. The objective of the present study was to assess the effects of a berry polyphenolic fraction (Orophenol®) composed of extracts from cranberry, wild blueberry, and strawberry on the main pathogenic determinants of . Orophenol® attenuated the growth of and decreased its hemolytic activity, its adherence to a basement membrane matrix model, and its proteinase activities. The berry polyphenolic fraction also impaired the production of reactive oxygen species (ROS) by oral keratinocytes stimulated with . Lastly, using an model of oral keratinocyte barrier, the fraction exerted a protective effect against the damages mediated by . In conclusion, the berry polyphenolic fraction investigated in the present study attenuated several pathogenic properties of . Although future clinical investigations are required, our study provided evidence that the polyphenols contained in this fraction may represent bioactive molecules of high interest for the prevention and/or treatment of periodontal disease.
表达了多种毒力因子,使其能够在牙周炎的病因发病机制中发挥核心作用。本研究的目的是评估一种由蔓越莓、野生蓝莓和草莓提取物组成的浆果多酚组分(Orophenol®)对……主要致病决定因素的影响。Orophenol®减弱了……的生长,降低了其溶血活性、对基底膜基质模型的黏附以及其蛋白酶活性。该浆果多酚组分还损害了由……刺激的口腔角质形成细胞产生的活性氧(ROS)。最后,使用口腔角质形成细胞屏障的……模型,该组分对由……介导的损伤发挥了保护作用。总之,本研究中所研究的浆果多酚组分减弱了……的几种致病特性。尽管需要未来的临床研究,但我们的研究提供了证据,表明该组分中含有的多酚可能是对预防和/或治疗牙周疾病具有高度兴趣的生物活性分子。
