Platelets interact with activated endothelial cells and have been implicated in the pathogenesis of some forms of acute lung injury. Autopsy studies have revealed pulmonary microthrombi after influenza infection, and epidemiological studies suggest that influenza vaccination is protective against pulmonary thromboembolism; however, the effect of influenza infection on platelet-endothelial interactions is unclear. We demonstrate that endothelial infection with both laboratory and clinical strains of influenza virus increased the adhesion of human platelets to primary human lung microvascular endothelial cells. Platelets adhered to infected cells as well as to neighboring cells, suggesting a paracrine effect. Influenza infection caused the upregulation of von Willebrand factor and ICAM-1, but blocking these receptors did not prevent platelet-endothelial adhesion. Instead, platelet adhesion was inhibited by both RGDS peptide and a blocking antibody to platelet integrin \u03b1\n            <jats:sub>5<\/jats:sub>\n            \u03b2\n            <jats:sub>1<\/jats:sub>\n            , implicating endothelial fibronectin. Concordantly, lung histology from infected mice revealed viral dose-dependent colocalization of viral nucleoprotein and the endothelial marker PECAM-1, while platelet adhesion and fibronectin deposition also were observed in the lungs of influenza-infected mice. Inhibition of platelets using acetylsalicylic acid significantly improved survival, a finding confirmed using a second antiplatelet agent. Thus, influenza infection induces platelet-lung endothelial adhesion via fibronectin, contributing to mortality from acute lung injury. The inhibition of platelets may constitute a practical adjunctive strategy to the treatment of severe infections with influenza.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>IMPORTANCE<\/jats:bold>\n            There is growing appreciation of the involvement of the lung endothelium in the pathogenesis of severe infections with influenza virus. We have recently shown that the virus can infect human lung endothelial cells, but the functional consequences of this infection are unknown (S. M. Armstrong, C. Wang, J. Tigdi, X. Si, C. Dumpit, S. Charles, A. Gamage, T. J. Moraes, and W. L. Lee, PLoS One 7:e47323, 2012,\n            <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"http:\/\/dx.doi.org\/10.1371\/journal.pone.0047323\">http:\/\/dx.doi.org\/10.1371\/journal.pone.0047323<\/jats:ext-link>\n            ). Here, we show that this infection causes platelets to adhere to the lung endothelium. Importantly, blocking platelets using two distinct antiplatelet drugs improved survival in a mouse model of severe influenza infection. Thus, platelet inhibition may constitute a novel therapeutic strategy to improve the host response to severe infections with influenza.\n          <\/jats:p>","DOI":"10.1128\/jvi.02599-15","type":"journal-article","created":{"date-parts":[[2015,12,5]],"date-time":"2015-12-05T02:53:36Z","timestamp":1449284016000},"page":"1812-1823","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":66,"title":["Influenza Virus Infection Induces Platelet-Endothelial Adhesion Which Contributes to Lung Injury"],"prefix":"10.1128","volume":"90","author":[{"given":"Michael G.","family":"Sugiyama","sequence":"first","affiliation":[{"name":"Keenan Research Centre for Biomedical Science, Li Ka Shing Knowledge Institute of St. Michael's Hospital, Toronto, Canada"},{"name":"Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asela","family":"Gamage","sequence":"additional","affiliation":[{"name":"Keenan Research Centre for Biomedical Science, Li Ka Shing Knowledge Institute of St. Michael's Hospital, Toronto, Canada"},{"name":"Institute of Medical Science, University of Toronto, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roman","family":"Zyla","sequence":"additional","affiliation":[{"name":"Keenan Research Centre for Biomedical Science, Li Ka Shing Knowledge Institute of St. Michael's Hospital, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan M.","family":"Armstrong","sequence":"additional","affiliation":[{"name":"Keenan Research Centre for Biomedical Science, Li Ka Shing Knowledge Institute of St. Michael's Hospital, Toronto, Canada"},{"name":"Institute of Medical Science, University of Toronto, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suzanne","family":"Advani","sequence":"additional","affiliation":[{"name":"Keenan Research Centre for Biomedical Science, Li Ka Shing Knowledge Institute of St. Michael's Hospital, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Advani","sequence":"additional","affiliation":[{"name":"Keenan Research Centre for Biomedical Science, Li Ka Shing Knowledge Institute of St. Michael's Hospital, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changsen","family":"Wang","sequence":"additional","affiliation":[{"name":"Keenan Research Centre for Biomedical Science, Li Ka Shing Knowledge Institute of St. Michael's Hospital, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Warren L.","family":"Lee","sequence":"additional","affiliation":[{"name":"Keenan Research Centre for Biomedical Science, Li Ka Shing Knowledge Institute of St. Michael's Hospital, Toronto, Canada"},{"name":"Institute of Medical Science, University of Toronto, Toronto, Canada"},{"name":"Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, Canada"},{"name":"Division of Respirology and Interdepartmental Division of Critical Care Medicine, University of Toronto, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.289.2.179"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0950268807007923"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1172\/JCI103791"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1086\/591708"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2009.1536"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.164.5.2103040"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1165\/rcmb.2014-0373OC"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1086\/523584"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1097\/QCO.0b013e32834cfb43"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.vaccine.2008.07.025"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1083\/jcb.21.3.367"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1099\/0022-1317-76-11-2869"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0047323"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1172\/JCI29499"},{"key":"e_1_3_2_16_2","first-page":"3450","article-title":"Platelet depletion and aspirin treatment protect mice in a two-event model of transfusion-related acute lung injury","volume":"119","author":"Looney MR","year":"2009","unstructured":"Looney MR, Nguyen JX, Hu Y, Van Ziffle JA, Lowell CA, Matthay MA. 2009.
