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.
