摘要 【目的】探讨猪圆环病毒2型(PCV2)感染猪小肠上皮细胞(IPEC-J2)后,IPEC-J2中病毒载量和部分炎性因子的变化。【方法】病毒感染IPEC-J2细胞,于不同时间收取样品,提取总DNA,用荧光定量PCR方法测定病毒载量变化;提取总RNA反转录,用荧光定量PCR方法测定IL-6、TGF-β1、IL-12的含量变化。【结果】病毒载量随时间持续增高,且在72h达到顶峰。IL-6在48h显示明显上调,24h下调;TGF-β1在12h和72h均明显上调;IL-12在不同时间点变化不大。【结论】PCV2可在IPEC-J2中增殖,上调IPEC-J2中IL-6和TGF-β1的表达。该结论为进一步研究PCV2的肠道免疫致病机制提供研究数据。
