沙粒病毒在人类中引起致命的出血性疾病。旧世界沙粒病毒糖蛋白(GP)主要与α-肌营养不良蛋白聚糖(α-dystroglycan)结合作为细胞表面受体,而新世界沙粒病毒则劫持转铁蛋白受体。然而,Lujo病毒(LUJV)糖蛋白不与新世界或旧世界沙粒病毒簇集。使用重组水泡性口炎病毒含有LUJV糖蛋白(LUJV GP)作为其唯一的附件和融合蛋白(VSV-LUJV),我们证明了感染是独立的已知沙粒病毒受体基因。全基因组单倍体遗传筛选鉴定跨膜蛋白神经纤毛蛋白2(NRP 2)和四跨膜蛋白CD 63为LUJV GP介导的感染的因子。LUJV GP结合NRP 2的N-末端结构域,而CD 63刺激pH激活的LUJV GP介导的膜融合。NRP 2或其N-末端结构域的过表达增强VSV-LUJV感染,并且缺乏NRP 2的细胞在野生型LUJV感染中是缺陷的。这些发现揭示了LUJV感染中的这组独特的宿主细胞进入因子,并且是治疗干预的有吸引力的焦点。
Arenaviruses cause fatal haemorrhagic disease in humans. Old-World arenavirus glycoproteins (GPs) mainly engage α-dystroglycan as a cell surface receptor, while New-World arenaviruses hijack transferrin receptor. However, the Lujo virus (LUJV) glycoprotein does not cluster with New-or Old-world arenaviruses. Using a recombinant vesicular stomatitis virus containing LUJV glycoprotein (LUJV GP) as its sole attachment and fusion protein (VSV-LUJV), we demonstrate that infection is independent of known arenavirus receptor genes. A genome-wide haploid genetic screen identified the transmembrane protein neuropilin 2 (NRP2) and tetraspanin CD63 as factors for LUJV GP-mediated infection. LUJV GP binds the N-terminal domain of NRP2, while CD63 stimulates pH-activated LUJV GP-mediated membrane fusion. Overexpression of NRP2 or its N-terminal domain enhances VSV-LUJV infection, and cells lacking NRP2 are deficient in wild-type LUJV infection. These findings uncover this distinct set of host cell entry factors in LUJV infection and are attractive focus points for therapeutic intervention.
