摘要(Abstract):
为分析猪日本乙型脑炎病毒(JEV)感染猪外周血单核细胞后对其促炎因子转录的影响,探讨JEV感染的分子免疫致病机制。采用real-time RT-PCR方法,测定并分析了JEV感染猪外周血单核细胞(PBMC)后病毒RNA含量及白细胞介素(IL-8、IL-12p35、IL-12p40、IL-17、IL-18)炎性细胞因子mRNA转录时相的变化。结果显示,JEV感染猪PBMC后引起IL-8,IL-12p35和p40的分泌呈现不规则的曲线,IL-18表达量持续升高;IL-17表达量持续下降,仅在感染后48 h的时候达到峰值。以上结果表明,JEV感染PBMC可促使炎性因子分泌增加,参与细胞免疫应答。
