However, there has not been any\n            <jats:italic>in vivo<\/jats:italic>\n            study of SIVcpz infection of humans. Also, it remains largely unknown why only specific SIVcpz strains have achieved cross-species transmission and what transmission risk might exist for those SIVcpz strains that have not been found to infect humans. Closing this knowledge gap is essential for better understanding cross-species transmission and predicting the likelihood of additional cross-species transmissions of SIV into humans. Here we show that humanized bone marrow, thymus, and liver (hu-BLT) mice are susceptible to all studied strains of SIVcpz, including the inferred ancestral viruses of pandemic and nonpandemic HIV-1 groups M (SIVcpzMB897) and N (SIVcpzEK505) as well as strains that have not been found in humans (SIVcpzMT145 and SIVcpzBF1167). Importantly, the ability of SIVcpz to cross the interspecies barrier to infect humanized mice correlates with their phylogenetic distance to pandemic HIV-1. We also identified mutations of SIVcpzMB897 (Env G411R and G413R) and SIVcpzBF1167 (Env H280Q and Q380R) at 14 weeks postinoculation. Together, our results have recapitulated the events of SIVcpz cross-species transmission to humans and identified mutations that occurred during the first 16 weeks of infection, providing\n            <jats:italic>in vivo<\/jats:italic>\n            experimental evidence that the origins of HIV-1 are the consequence of SIVcpz crossing over to humans. This study also revealed that SIVcpz viruses whose inferred descendants have not been found in humans still have the potential to cause an HIV-1-like zoonosis.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>IMPORTANCE<\/jats:bold>\n            It is believed that the origins of HIV-1 are the consequence of SIV from wild chimpanzees crossing over to humans. However, the origins of HIV-1 have been linked back to only specific SIVcpz strains. There have been no experiments that directly test the\n            <jats:italic>in vivo<\/jats:italic>\n            cross-species transmissibility of SIVcpz strains to humans. This is the first\n            <jats:italic>in vivo<\/jats:italic>\n            study of SIVcpz cross-species transmission. With the humanized-BLT mouse model, we have provided\n            <jats:italic>in vivo<\/jats:italic>\n            experimental evidence of multiple SIVcpz strains crossing over to humans and identified several important mutations of divergent SIVcpz strains after long-term replication in human cells. We also found that the cross-species transmission barrier of SIVcpz to humans correlates with their phylogenetic distance to pandemic HIV-1 group M. Importantly, this work provides evidence that SIVcpz viruses, whose inferred descendants have not been found in humans, still have the potential to cause a future HIV-1-like zoonotic outbreak.\n          <\/jats:p>","DOI":"10.1128\/jvi.00860-16","type":"journal-article","created":{"date-parts":[[2016,6,16]],"date-time":"2016-06-16T05:49:16Z","timestamp":1466056156000},"page":"7728-7739","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":36,"title":["Recapitulating Cross-Species Transmission of Simian Immunodeficiency Virus SIVcpz to Humans by Using Humanized BLT Mice"],"prefix":"10.1128","volume":"90","author":[{"given":"Zhe","family":"Yuan","sequence":"first","affiliation":[{"name":"Nebraska Center for Virology, School of Biological Sciences, University of Nebraska\u2014Lincoln, Lincoln, Nebraska, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guobin","family":"Kang","sequence":"additional","affiliation":[{"name":"Nebraska Center for Virology, School of Biological Sciences, University of Nebraska\u2014Lincoln, Lincoln, Nebraska, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fangrui","family":"Ma","sequence":"additional","affiliation":[{"name":"Nebraska Center for Virology, School of Biological Sciences, University of Nebraska\u2014Lincoln, Lincoln, Nebraska, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wuxun","family":"Lu","sequence":"additional","affiliation":[{"name":"Nebraska Center for Virology, School of Biological Sciences, University of Nebraska\u2014Lincoln, Lincoln, Nebraska, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenjin","family":"Fan","sequence":"additional","affiliation":[{"name":"Nebraska Center for Virology, School of Biological Sciences, University of Nebraska\u2014Lincoln, Lincoln, Nebraska, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christine M.","family":"Fennessey","sequence":"additional","affiliation":[{"name":"AIDS and Cancer Virus Program, Leidos Biomedical Research, Inc., Frederick National Laboratory for Cancer Research, Frederick, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brandon F.","family":"Keele","sequence":"additional","affiliation":[{"name":"AIDS and Cancer Virus Program, Leidos Biomedical Research, Inc., Frederick National Laboratory for Cancer Research, Frederick, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingsheng","family":"Li","sequence":"additional","affiliation":[{"name":"Nebraska Center for Virology, School of Biological Sciences, University of Nebraska\u2014Lincoln, Lincoln, Nebraska, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/ni.2735"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1256739"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/molbev\/msg207"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1101\/cshperspect.a006841"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1038\/345356a0"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1126531"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1038\/17130"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.287.5453.607"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.00012-13"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.295.5554.465"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1038\/428820a"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.79.7.3891-3902.2005"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1097\/00002030-198910000-00001"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1038\/nri3311"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1038\/nm1431"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.00009-06"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1318175111"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1097\/QAI.0000000000000687"},{"key":"e_1_3_2_20_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.78.20.11130-11141.2004"},{"key":"e_1_3_2_21_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature03513"},{"key":"e_1_3_2_22_2","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/gkh340"},{"key":"e_1_3_2_23_2","doi-asserted-by":"publisher","DOI":"10.1093\/sysbio\/syq010"},{"key":"e_1_3_2_24_2","doi-asserted-by":"publisher","DOI":"10.1002\/jcc.20084"},{"key":"e_1_3_2_25_2","doi-asserted-by":"publisher","DOI":"10.1101\/gr.849004"},{"key":"e_1_3_2_26_2","volume-title":"Applied survival analysis","author":"Le CT","year":"1997","unstructured":"Le CT. 1997.
