We also showed that RV replication is required for barrier function disruption. However, the underlying biochemical mechanisms are not known. In the present study, we found that a double-stranded RNA (dsRNA) mimetic, poly(I:C), induced tight junction breakdown and facilitated bacterial transmigration across polarized airway epithelial cells, similar to the case with RV. We also found that RV and poly(I:C) each stimulated Rac1 activation, reactive oxygen species (ROS) generation, and Rac1-dependent NADPH oxidase 1 (NOX1) activity. Inhibitors of Rac1 (NSC23766), NOX (diphenylene iodonium), and NOX1 (small interfering RNA [siRNA]) each blocked the disruptive effects of RV and poly(I:C) on R\n            <jats:sub>T<\/jats:sub>\n            , as well as the dissociation of ZO-1 and occludin from the tight junction complex. Finally, we found that Toll-like receptor 3 (TLR3) is not required for either poly(I:C)- or RV-induced reductions in R\n            <jats:sub>T<\/jats:sub>\n            . Based on these results, we concluded that Rac1-dependent NOX1 activity is required for RV- or poly(I:C)-induced ROS generation, which in turn disrupts the barrier function of polarized airway epithelia. Furthermore, these data suggest that dsRNA generated during RV replication is sufficient to disrupt barrier function.\n          <\/jats:p>","DOI":"10.1128\/jvi.02074-10","type":"journal-article","created":{"date-parts":[[2011,4,22]],"date-time":"2011-04-22T00:14:32Z","timestamp":1303431272000},"page":"6795-6808","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":105,"title":["Rhinovirus-Induced Barrier Dysfunction in Polarized Airway Epithelial Cells Is Mediated by NADPH Oxidase 1"],"prefix":"10.1128","volume":"85","author":[{"given":"Adam T.","family":"Comstock","sequence":"first","affiliation":[{"name":"Department of Pediatrics and Communicable Diseases, University of Michigan, Ann Arbor, Michigan 48109"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shyamala","family":"Ganesan","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Communicable Diseases, University of Michigan, Ann Arbor, Michigan 48109"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asamanja","family":"Chattoraj","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Communicable Diseases, University of Michigan, Ann Arbor, Michigan 48109"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea N.","family":"Faris","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Communicable Diseases, University of Michigan, Ann Arbor, Michigan 48109"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin L.","family":"Margolis","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, University of Michigan, Ann Arbor, Michigan 48109"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc B.","family":"Hershenson","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Communicable Diseases, University of Michigan, Ann Arbor, Michigan 48109"},{"name":"Department of Molecular and Integrative Physiology, University of Michigan, Ann Arbor, Michigan 48109"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Umadevi S.","family":"Sajjan","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Communicable Diseases, University of Michigan, Ann Arbor, Michigan 48109"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1128\/jcm.35.11.2864-2868.1997"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.80.4.1629-1636.2006"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1152\/physrev.00044.2005"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cellsig.2008.12.001"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0891-5849(98)00233-0"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/jcp.10451"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1097\/INF.0b013e31812e52e6"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M512751200"},{"key":"e_1_3_2_10_2","first-page":"467","article-title":"Viral infections in exacerbations of asthma and chronic obstructive pulmonary disease","volume":"100","author":"Contoli M.","year":"2009","unstructured":"ContoliM. . 2009.
