Molecules:Melittin可减弱PgLPS诱导的炎症反应用于牙周炎的治疗

2018-05-09 MedSci MedSci原创

牙周炎是一种慢性炎症性疾病,可导致牙周组织的破坏。牙龈卟啉单胞菌可通过其致病性脂多糖(LPS)引起牙周炎。Melittin是蜜蜂毒的主要成分,已知具有抗炎和抗菌作用。然而,蜂毒素在炎症反应中的作用尚未在牙周炎样人角质形成细胞中阐明。本研究旨在阐明蜂毒素对牙龈卟啉单胞菌LPS(PgLPS)处理的HaCaT人角质形成细胞系的抗炎作用。使用人角质形成细胞系HaCaT和细胞计数试剂盒-8来评估蜂毒素的细胞

牙周炎是一种慢性炎症性疾病,可导致牙周组织的破坏。牙龈卟啉单胞菌可通过其致病性脂多糖(LPS)引起牙周炎。Melittin是蜜蜂毒的主要成分,已知具有抗炎和抗菌作用。然而,蜂毒素在炎症反应中的作用尚未在牙周炎样人角质形成细胞中阐明。本研究旨在阐明蜂毒素对牙龈卟啉单胞菌LPS(PgLPS)处理的HaCaT人角质形成细胞系的抗炎作用。

使用人角质形成细胞系HaCaT和细胞计数试剂盒-8来评估蜂毒素的细胞毒性。利用蛋白质印迹、实时定量PCT和免疫荧光确定蜂毒素对PgLPS诱导的炎症的作用。

结果显示,PgLPS可上调肿瘤坏死因子-α(TNF-α)、白细胞介素(IL)-6、IL-8和干扰素-γ(IFN-γ)等炎症因子的表达。此外,PgLPS诱导活化的B细胞(NF-κB)、细胞外信号调节激酶(ERK)和蛋白激酶B/Akt的核因子κ-轻链增强子的激活。Melittin还通过抑制NF-κB信号通路、ERK和Akt的活化来抑制促炎细胞因子的表达。

综上所述,该研究结果表明,Melittin可减弱PgLPS诱导的炎症反应,因此可用于治疗牙周炎以达到抗炎效果。
