摘要 为进一步了解猪圆环病毒2型(PCV2)引起断奶仔猪多系统衰竭综合征的机理,选取5头35日龄PCV2血清抗体阴性的断奶仔猪,无菌取脾脏制成单个细胞悬液,体外培养,分PCV2感染组与对照组。分别在培养后0 h、6 h、12 h、24 h收获细胞培养上清,用猪特异性ELISA试剂盒测定上清中白细胞介素-1β(IL-1β)、肿瘤坏死因子-α(TNF-α)、白细胞介素6(IL-6)和白细胞介素10(IL-10)的含量。结果显示:病毒组IL-1β和IL-6在不同时间点的含量变化均不显著(P>0.05),IL-1β在6 h、24 h略高于对照组,12 h则低于对照组;IL-6除在6 h高于对照组外,其余时间点均低于对照组;病毒组TNF-α和IL-10的含量在6 h、12 h、24 h均高于对照组,且TNF-α在6 h和24 h极显著升高(P<0.01),而IL-10在12 h显著高于对照组(P<0.05)。上述结果表明:PCV2能影响体外培养的仔猪脾细胞某些细胞因子的分泌,而且可能通过TNF-α的高表达促使机体产生全身炎症反应综合征甚至多系统衰竭,而通过IL-10的高表达促使机体产生免疫抑制。
