摘要 目的:观察荆芥挥发油(VOHS)对流感病毒性肺炎小鼠Myd88、TRAF6蛋白表达的影响,探讨荆芥挥发油治疗流感病毒性肺炎的细胞信号调控转导机制。方法:60只小鼠随机分为6组,分别为空白对照组、模型对照组、阳性药对照组(利巴韦林),VOHS预防给药组(0.110mg/kg)、VOHS高剂量组(0.110mg/kg),VOHS低剂量组(0.028mg/kg),灌胃给药,除预防给药组于造模前3d给药外,其余各组均于造模前1d给药。以10倍LD50浓度的流感病毒滴鼻感染,第6d处死动物。用Western blotting法检测小鼠肺组织中Myd88、TRAF6蛋白表达。结果:与模型对照组比较,VOHS预防组可显著降低小鼠肺组织中的TRAF6相对蛋白表达量,差异有统计学意义,对于Myd88蛋白表达有一定抑制趋势,但无统计学意义。结论:荆芥挥发油可通过抑制TLR信号转导通路的重要接头分子Myd88和关键分子TRAF6的蛋白表达对抗流感病毒性肺炎。
