An inappropriate inflammatory response is the cause of many common diseases, especially periodontitis. Considering that no studies have been carried out to investigate the effect of IL-36γ on chronic periodontitis, this study aimed to investigate the inflammatory mechanism of IL-36γ by stimulating macrophage cells using NF-KB pathway.
This experimental study was performed on 50 healthy individuals and 50 subjects with chronic periodontitis. In this study, macrophage cells were extracted first, and then RNA was isolated from all the samples using TRIzol method. Subsequently, the rate of IL-36γ gene expression was analyzed and compared using real-time PCR technique. Additionally, immunofluorescence (IF) technique was used to investigate the rate of inflammation. The rate of NF-Kb expression was also measured via western blot technique. Finally, statistical analysis of the samples was carried out using appropriate statistical methods with SPSS 17.
The results showed that the rate of IL-36γ expression in subjects with periodontitis was higher compared to healthy subjects (P<0.05). Moreover, the results showed that following treatment of cells with TLR4, the rate of IL36γ expression increased significantly, especially during the 12-hour period after treatment.
This indicates that after stimulating the TLR pathways, the rate of IL-36γ expression will probably increase.
不适当的炎症反应是许多常见疾病的病因,尤其是牙周炎。鉴于尚未开展研究来探究白细胞介素-36γ(IL-36γ)对慢性牙周炎的影响,本研究旨在通过使用核因子-κB(NF-κB)途径刺激巨噬细胞来探究IL-36γ的炎症机制。
本实验研究对50名健康个体和50名慢性牙周炎患者进行。在本研究中,首先提取巨噬细胞,然后使用TRIzol法从所有样本中分离RNA。随后,使用实时聚合酶链反应(PCR)技术分析并比较IL-36γ基因表达率。此外,采用免疫荧光(IF)技术来研究炎症率。还通过蛋白质印迹技术测量NF-κB的表达率。最后,使用SPSS 17软件的适当统计方法对样本进行统计分析。
结果显示,牙周炎患者的IL-36γ表达率高于健康受试者(P<0.05)。此外,结果表明,用Toll样受体4(TLR4)处理细胞后,IL-36γ表达率显著增加,尤其是在处理后的12小时内。
这表明刺激TLR途径后,IL-36γ的表达率可能会增加。
