In this paper, we provide evidence that the large guanosine triphosphatase dynamin2 and its partner, endothelial nitric oxide (NO) synthase (NOS [eNOS]), mediate bacterial entry. Overexpression of dynamin2 or treatment with the NO donor S-nitrosothiols increases, whereas targeted reduction of endogenous dynamin2 or eNOS expression with ribonucleic acid interference impairs, bacterial invasion. Exposure of mouse bladder to small molecule NOS inhibitors abrogates infection of the uroepithelium by E. coli, and, concordantly, bacteria more efficiently invade uroepithelia isolated from wild-type compared with eNOS\u2212\/\u2212 mice. E. coli internalization promotes rapid phosphorylation of host cell eNOS and NO generation, and dynamin2 S-nitrosylation, a posttranslational modification required for the bacterial entry, also increases during E. coli invasion. These findings suggest that UPEC escape urinary flushing and immune cell surveillance by means of eNOS-dependent dynamin2 S-nitrosylation and invasion of host cells to cause recurrent UTIs.<\/jats:p>","DOI":"10.1083\/jcb.201003027","type":"journal-article","created":{"date-parts":[[2011,1,10]],"date-time":"2011-01-10T17:09:43Z","timestamp":1294679383000},"page":"101-110","update-policy":"https:\/\/doi.org\/10.1083\/jcb.crossmarkpolicy","source":"Crossref","is-referenced-by-count":29,"title":["Dynamin2- and endothelial nitric oxide synthase\u2013regulated invasion of bladder epithelial cells by uropathogenic<i>Escherichia coli<\/i>"],"prefix":"10.1083","volume":"192","author":[{"given":"Zhimin","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Pathology, Medical College of Georgia, Augusta, GA 30912 1"},{"name":"Department of Urology 4 and 5"},{"name":"Prostate Disease Center, University of Florida, Gainesville, FL 32610 4 and 5"},{"name":"Department of Urology 4 and 5"},{"name":"Prostate Disease Center, University of Florida, Gainesville, FL 32610 4 and 5"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ceba","family":"Humphrey","sequence":"additional","affiliation":[{"name":"Department of Pathology, Medical College of Georgia, Augusta, GA 30912 1"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicole","family":"Frilot","sequence":"additional","affiliation":[{"name":"Department of Pathology, Medical College of Georgia, Augusta, GA 30912 1"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gaofeng","family":"Wang","sequence":"additional","affiliation":[{"name":"John P.
