Sci Rep :薄荷醇与间质性膀胱炎中的慢性炎症相关

2018-08-05 AlexYang MedSci原创

慢性炎症是许多膀胱功能障碍的一种潜在的系统性风险因子。包括了间质性膀胱炎(IC)。然而,一个健康的膀胱是通过怎样的机制来保护其免受炎症触发仍旧不清楚。最近,有研究人员从IC患者和健康对照的尿液中鉴定出了嗅味物质,并利用综合固相微萃取气相色谱飞行时间质谱法(PMNE-GC-TOF-MS)分析和生物信息分析发现了尿液中的挥发性代谢物水平,比如薄荷醇,与健康对照相比在IC患者中显著减少。为了理解挥发性代

慢性炎症是许多膀胱功能障碍的一种潜在的系统性风险因子。包括了间质性膀胱炎(IC)。然而,一个健康的膀胱是通过怎样的机制来保护其免受炎症触发仍旧不清楚。

最近,有研究人员从IC患者和健康对照的尿液中鉴定出了嗅味物质,并利用综合固相微萃取气相色谱飞行时间质谱法(PMNE-GC-TOF-MS)分析和生物信息分析发现了尿液中的挥发性代谢物水平,比如薄荷醇,与健康对照相比在IC患者中显著减少。为了理解挥发性代谢物数据的机制意义和薄荷醇在免疫系统中的作用,研究人员进行了2个独立的试验:细胞因子分析和DNA基因芯片。研究发现,脂多糖(LPS)刺激的炎症事件,比如炎症细胞因子的产生和分泌(比如TNF-α, IL-6和IL-1β)、NF-κB的激活以及在一个大的信号网络中相关的蛋白(比如Akt, TLR1, TNFAIP3和NF-κB)均由于薄荷醇的存在而受到抑制。

最后,研究人员指出,他们的发现扩宽了对尿液薄荷传在抑制炎症事件中的认知,并为挥发性物质和炎症相关的IC的减轻提供了潜在的新的治疗策略。
