裂谷热病毒(RVFV)是一种在非洲发现的新出现的虫媒病毒。虽然裂谷热病毒是嗜性的,感染许多细胞和组织,但肝脏内的病毒复制和坏死在介导严重疾病中起着关键作用。低密度脂蛋白受体相关蛋白1 (Lrp1)是最近发现的RVFV进入细胞和感染的宿主因子。然而,Lrp1的生物学意义,包括其在体内肝脏疾病中的作用,仍有待确定。由于Lrp1在肝细胞中具有高表达水平,我们建立了一种小鼠模型,在肝细胞中特异性地缺失Lrp1,以测试肝脏中Lrp1表达缺失如何影响裂谷热的发病机制。肝细胞中缺乏Lrp1表达的小鼠肝脏中RVFV复制最少,死亡时间更长,并且神经系统疾病的临床症状发生改变。相比之下,其他组织中的裂谷热病毒感染水平在两种基因型之间没有差异。因此,Lrp1对小鼠裂谷热肝脏疾病至关重要。Lrp1对裂谷热病至关重要。
Rift Valley fever virus (RVFV) is an emerging arbovirus found in Africa. While RVFV is pantropic and infects many cells and tissues, viral replication and necrosis within the liver play a critical role in mediating severe disease. The low-density lipoprotein receptor–related protein 1 (Lrp1) is a recently identified host factor for cellular entry and infection by RVFV. The biological significance of Lrp1, including its role in hepatic disease in vivo, however, remains to be determined. Because Lrp1 has a high expression level in hepatocytes, we developed a mouse model in which Lrp1 is specifically deleted in hepatocytes to test how the absence of liver Lrp1 expression affects RVF pathogenesis. Mice lacking Lrp1 expression in hepatocytes showed minimal RVFV replication in the liver, longer time to death, and altered clinical signs toward neurological disease. In contrast, RVFV infection levels in other tissues showed no difference between the two genotypes. Therefore, Lrp1 is essential for RVF hepatic disease in mice. Lrp1 is essential for Rift Valley fever disease.
