猪繁殖与呼吸综合征是一种传染性疾病,给世界范围内的养猪业造成严重的经济损失。为了更好地了解猪繁殖与呼吸综合征病毒(PRRSV)的发病机制,采用3株具有不同分子标记和毒力的PRRSV感染MARC-145细胞。共鉴定出1804个蛋白,233个蛋白和72个信号通路参与病毒感染的MARC-145细胞的蛋白质组学分析,随着PRRSV毒株的毒力增加。这三种类型的病毒株在被感染的marc -145细胞中有一个共同的途径——线粒体中的电子传递反应。此外,反义信号通路是SX-1毒株高毒力的所有重要信号通路中变化最大的,表明这一独特的信号通路可能与SX-1毒株的高毒力有关。我们的研究是首次尝试提供不同毒力的PRRSV毒株感染的MARC-145细胞的蛋白质组谱,这些发现将有助于深入了解该病毒与其宿主之间的相互作用。
Porcine reproductive and respiratory syndrome is an infectious disease that causes serious economic losses to the swine industry worldwide. To better understand the pathogenesis of the porcine reproductive and respiratory syndrome virus (PRRSV), three PRRSV strains with different molecular markers and virulence were used to infect MARC-145 cells. A total of 1804 proteins were identified, and 233 altered proteins and 72 signaling pathways involved in the proteomic profiling of virus-infected MARC-145 cells increased with the virulence of the PRRSV strain. The three types of viral strains shared a common pathway—the electron transport reaction in mitochondria—in the infected-MARC-145 cells. Moreover, the antisense pathway was the most variable of all significant signaling pathways for the highly virulent SX-1 strain, indicating that this unique pathway may be connected to the high virulence of the SX-1 strain. Our study is the first attempt to provide a proteome profile of MARC-145 cells infected with PRRSV strains with different virulence, and these findings will facilitate a deep understanding of the interactions between this virus and its host.
