Host factors mediating the cellular entry of OROV are undefined. Here, we show that OROV uses the host protein low-density lipoprotein\u2013related protein 1 (Lrp1) for efficient cellular infection. Cells from evolutionarily distinct species lacking Lrp1 were less permissive to OROV infection than cells with Lrp1. Treatment of cells with either the high-affinity Lrp1 ligand receptor-associated protein (RAP) or recombinant ectodomain truncations of Lrp1 significantly reduced OROV infection. In addition, chimeric vesicular stomatitis virus (VSV) expressing OROV glycoproteins (VSV-OROV) bound to the Lrp1 ectodomain in\u00a0vitro. Furthermore, we demonstrate the biological relevance of the OROV-Lrp1 interaction in a proof-of-concept mouse study in which treatment of mice with RAP at the time of infection reduced tissue viral load and promoted survival from an otherwise lethal infection. These results with OROV, along with the recent finding of Lrp1 as an entry factor for Rift Valley fever virus, highlight the broader significance of Lrp1 in cellular infection by diverse bunyaviruses. Shared strategies for entry, such as the critical function of Lrp1 defined here, provide a foundation for the development of pan-bunyaviral therapeutics.\n                  <\/jats:p>","DOI":"10.1073\/pnas.2204706119","type":"journal-article","created":{"date-parts":[[2022,8,8]],"date-time":"2022-08-08T15:16:07Z","timestamp":1659971767000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":73,"title":["Oropouche orthobunyavirus infection is mediated by the cellular host factor Lrp1"],"prefix":"10.1073","volume":"119","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9038-4655","authenticated-orcid":false,"given":"Madeline M.","family":"Schwarz","sequence":"first","affiliation":[{"name":"Center for Vaccine Research, School of Medicine, University of Pittsburgh, Pittsburgh, PA 15213"},{"name":"Department of Infectious Diseases and Microbiology, School of Public Health, University of Pittsburgh, Pittsburgh, PA 15213"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A.","family":"Price","sequence":"additional","affiliation":[{"name":"Department of Medicine, Washington University School of Medicine, St. Louis, MO 63110"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9014-6577","authenticated-orcid":false,"given":"Safder S.","family":"Ganaie","sequence":"additional","affiliation":[{"name":"Department of Pathology and Immunology, Washington University School of Medicine in St. Louis, St. Louis, MO 63110"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annie","family":"Feng","sequence":"additional","affiliation":[{"name":"Department of Pathology and Immunology, Washington University School of Medicine in St. Louis, St. Louis, MO 63110"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nawneet","family":"Mishra","sequence":"additional","affiliation":[{"name":"Department of Pathology and Immunology, Washington University School of Medicine in St. Louis, St. Louis, MO 63110"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan M.","family":"Hoehl","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases and Microbiology, School of Public Health, University of Pittsburgh, Pittsburgh, PA 15213"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6807-9670","authenticated-orcid":false,"given":"Farheen","family":"Fatma","sequence":"additional","affiliation":[{"name":"Department of Pathology and Immunology, Washington University School of Medicine in St. Louis, St. Louis, MO 63110"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3261-191X","authenticated-orcid":false,"given":"Sarah H.","family":"Stubbs","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Harvard Medical School, Boston, MA, 02115"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1564-8590","authenticated-orcid":false,"given":"Sean P.
