虫媒病毒的生命周期涉及脊椎动物宿主和节肢动物载体之间的病毒转移,并且通过载体从受感染的哺乳动物宿主获得病毒是该过程中的重要步骤。在这里,我们报告说,黄病毒非结构蛋白-1(NS 1),这是大量分泌到血清中的感染主机,起着至关重要的作用,在黄病毒收购蚊子。感染的干扰素-α和γ受体缺陷小鼠(AG 6)血液中存在登革病毒(DENV)和日本脑炎病毒NS 1,这有助于其原生蚊子载体获得病毒,因为这种蛋白质使病毒能够克服蚊子中肠的免疫屏障。用修饰的DENV NS 1主动免疫AG 6小鼠减少了蚊子对DENV的获取,并保护小鼠免受致命的DENV攻击,这表明用NS 1免疫可以减少携带病毒的蚊子的数量以及黄病毒疾病的发病率。我们的研究表明,黄病毒利用NS 1蛋白在其脊椎动物阶段,以提高其收购的载体,这可能是由于黄病毒进化,以适应多种宿主环境。
The arbovirus life cycle involves viral transfer between a vertebrate host and an arthropod vector, and acquisition of virus from an infected mammalian host by a vector is an essential step in this process. Here, we report that flavivirus nonstructural protein-1 (NS1), which is abundantly secreted into the serum of an infected host, plays a critical role in flavivirus acquisition by mosquitoes. The presence of dengue virus (DENV) and Japanese encephalitis virus NS1s in the blood of infected interferon-α and γ receptor-deficient mice (AG6) facilitated virus acquisition by their native mosquito vectors because the protein enabled the virus to overcome the immune barrier of the mosquito midgut. Active immunization of AG6 mice with a modified DENV NS1 reduced DENV acquisition by mosquitoes and protected mice against a lethal DENV challenge, suggesting that immunization with NS1 could reduce the number of virus-carrying mosquitoes as well as the incidence of flaviviral diseases. Our study demonstrates that flaviviruses utilize NS1 proteins produced during their vertebrate phases to enhance their acquisition by vectors, which might be a result of flavivirus evolution to adapt to multiple host environments.
