J Periodontol:牙龈卟啉单胞菌的可溶性因子抑制滋养细胞浸润

2017-11-24 MedSci MedSci原创

牙周炎是影响支持组织的慢性炎症疾病。牙周炎患者的妊娠并发症风险增加;然而,其病理生理学机制仍然不清楚。此外,牙龈卟啉单胞菌(Pg)在妊娠病人的少量胎盘中可检测到。因此,本研究的目的是研究Pg产生的可溶性因子对体外滋养细胞侵袭作用,以阐明牙周炎对妊娠结局的影响。

牙周炎是影响支持组织的慢性炎症疾病。牙周炎患者的妊娠并发症风险增加;然而,其病理生理学机制仍然不清楚。此外,牙龈卟啉单胞菌(Pg)在妊娠病人的少量胎盘中可检测到。因此,本研究的目的是研究Pg产生的可溶性因子对体外滋养细胞侵袭作用,以阐明牙周炎对妊娠结局的影响。

方法:将滋养层细胞系HTR-8 / SVneo置于培养板上或通过悬滴培养进行培养,以评估Pg在培养上清液(PG-sup)的存活率,细胞凋亡和形态。将细胞溶解在富含细胞外基质的膜制备板上以评估细胞侵袭力。通过立体显微镜,光学显微镜和透射电子显微镜评估形态学变化。

结果:培养24小时后,PG-sup以剂量依赖的方式抑制细胞侵袭。尽管细胞活力和凋亡计数不受PG-sup影响,但悬滴培养中的球体形成受到抑制。在PG-sup的存在下球体变得脆弱和不规则。透射电子显微镜显示微绒毛缩短和细胞间隙增加。

结论:PG-sup抑制滋养细胞浸润并影响其形态,但无直接的细胞毒作用。这些结果表明,Pg产生抑制滋养层侵入和随后血管重塑的可溶性因子,且会影响胎盘生长和胎儿健康。目前的研究结果可以解释牙周炎患者妊娠并发症发生率的增加。
