J Periodontol:牙周病中炎症小体调节转录的差异性表达

2020-05-31 网络 网络

炎症小体调节与牙周病发病机制相关的关键原发炎促炎细胞因子的释放。本研究旨在评估调节炎症小体的蛋白的表达,即POPs、CARD和TRIM蛋白在牙周病中的表达。

炎症小体调节与牙周病发病机制相关的关键原发炎促炎细胞因子的释放。本研究旨在评估调节炎症小体的蛋白的表达,即POPs、CARD和TRIM蛋白在牙周病中的表达。

本研究共纳入68名参与者(34名男性和34名女性),根据临床参数将其分为四组,包括牙周健康(H)、牙龈炎(G)、慢性牙周炎(CP)和侵袭性牙周炎(AgP)。获取受试者的牙龈组织样本,RT-PCR分析调控炎症小体表达的分子,包括ASC, caspase‐1,IL‐1β,IL‐18, nucleotide‐binding domain,NLRP3, NLRP2, AIM2 , POP1, POP2, CARD16, CARD18, TRIM16和TRIM20。

结果发现,与H组相比,NLRP3和IL-1β在G组、CP组和AgP组的表达上调(P <0.05)。与H组、G组和AgP组相比,AIM2在CP组的表达下调(P <0.05)。与H组相比,TRIM20、TRIM16和CARD18在G组、CP组和AgP组的表达下调(P <0.05)。POP1和POP2分别在CP和AgP、AgP和G组中的表达下调(P <0.05)。

因此,活动性牙周病可能导致炎性小体调节因子的下调,而牙周病中炎性小体调节因子可能会增加NLRP3和IL-1β的活性。
