The vast majority (\u223c11,000) of these occurred during the 2013-2016 West African epidemic. Three out of five species in the genus are known to cause Ebola Virus Disease in humans. Several monoclonal antibodies against the ebolavirus glycoprotein are currently in development as therapeutics. However, there is still a paucity of monoclonal antibodies that can cross-react between the glycoproteins of different ebolavirus species, and the mechanism of these monoclonal antibody therapeutics is still not understood in detail. Here, we generated a panel of eight murine monoclonal antibodies (MAbs) utilizing a prime-boost vaccination regimen with a\n            <jats:named-content content-type=\"genus-species\">Zaire ebolavirus<\/jats:named-content>\n            glycoprotein expression plasmid followed by infection with a vesicular stomatitis virus expressing the\n            <jats:named-content content-type=\"genus-species\">Zaire ebolavirus<\/jats:named-content>\n            glycoprotein. We tested the binding breadth of the resulting monoclonal antibodies using a set of recombinant surface glycoproteins from Reston, Ta\u00ef Forest, Bundibugyo, Zaire, Sudan, and Marburg viruses and found two antibodies that showed pan-ebolavirus binding.

Several of our antibodies, including the broadly binding ones, protected mice from mortality despite lacking neutralization capability\n            <jats:italic>in vitro<\/jats:italic>\n            , suggesting their protection may be mediated by Fc-FcR interactions. Indeed, three antibodies displayed cellular phagocytosis and\/or antibody-dependent cell-mediated cytotoxicity\n            <jats:italic>in vitro<\/jats:italic>\n            . Our antibodies, specifically the two identified cross-reactive monoclonal antibodies (KL-2E5 and KL-2H7), might add to the understanding of anti-ebolavirus humoral immunity.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>IMPORTANCE<\/jats:bold>\n            This study describes the generation of a panel of novel anti-ebolavirus glycoprotein monoclonal antibodies, including two antibodies with broad cross-reactivity to all known ebolavirus species. The antibodies were raised using a heterologous DNA-viral vector prime-boost regimen, resulting in a high proportion of cross-reactive antibodies (25%). Similar vaccination regimens have been used successfully to induce broad protection against influenza viruses in humans, and our limited data indicate that this might be a useful strategy for filovirus vaccines as well. Several of our antibodies showed protective efficacy when tested in a novel murine challenge model and may be developed into future therapeutics.\n          <\/jats:p>","DOI":"10.1128\/jvi.00652-17","type":"journal-article","created":{"date-parts":[[2017,6,8]],"date-time":"2017-06-08T00:40:24Z","timestamp":1496882424000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":37,"title":["Novel Cross-Reactive Monoclonal Antibodies against Ebolavirus Glycoproteins Show Protection in a Murine Challenge Model"],"prefix":"10.1128","volume":"91","author":[{"given":"James","family":"Duehr","sequence":"first","affiliation":[{"name":"Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY, USA"},{"name":"Graduate School of Biomedical Sciences, Icahn School of Medicine at Mount Sinai, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teddy John","family":"Wohlbold","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY, USA"},{"name":"Graduate School of Biomedical Sciences, Icahn School of Medicine at Mount Sinai, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa","family":"Oestereich","sequence":"additional","affiliation":[{"name":"Department of Virology, Bernhard Nocht Institute for Tropical Medicine, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronika","family":"Chromikova","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatima","family":"Amanat","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4451-9608","authenticated-orcid":false,"given":"Madhusudan","family":"Rajendran","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergio","family":"Gomez-Medina","sequence":"additional","affiliation":[{"name":"Heinrich Pette Institute, Leibniz Institute for Experimental Virology, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ignacio","family":"Mena","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY, USA"},{"name":"Global Health and Emerging Pathogens Institute, Icahn School of Medicine at Mount Sinai, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin R.","family":"tenOever","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adolfo","family":"Garc\u00eda-Sastre","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY, USA"},{"name":"Global Health and Emerging Pathogens Institute, Icahn School of Medicine at Mount Sinai, New York, NY, USA"},{"name":"Department of Medicine, Icahn School of Medicine at Mount Sinai, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher F.","family":"Basler","sequence":"additional","affiliation":[{"name":"Center for Microbial Pathogenesis, Institute for Biomedical Sciences, Georgia State University, Atlanta, Georgia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7725-2586","authenticated-orcid":false,"given":"Cesar","family":"Munoz-Fontela","sequence":"additional","affiliation":[{"name":"Department of Virology, Bernhard Nocht Institute for Tropical Medicine, Hamburg, Germany"},{"name":"Heinrich Pette Institute, Leibniz Institute for Experimental Virology, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4121-776X","authenticated-orcid":false,"given":"Florian","family":"Krammer","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","volume-title":"Impact of the West African Ebola virus disease outbreak on food security","author":"Thomas A-C","year":"2014","unstructured":"Thomas A-C Nkunzimana T Perez Hoyos A Kayitakire F . 2014.
