One mechanism protecting the mucosa is the rapid shedding of epithelial cells, also termed exfoliation, but it is unclear how pathogens counteract this process. We found that carcinoembryonic antigen (CEA)–binding bacteria colonized the urogenital tract of CEA transgenic mice, but not of wild-type mice, by suppressing exfoliation of mucosal cells. CEA binding triggered de novo expression of the transforming growth factor receptor CD105, changing focal adhesion composition and activating β1 integrins. This manipulation of integrin inside-out signaling promotes efficient mucosal colonization and represents a potential target to prevent or cure bacterial infections.</dcterms:abstract> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> <dc:rights>deposit-license</dc:rights> <dc:contributor>Zimmermann, Wolfgang</dc:contributor> <dc:contributor>Hauck, Christof</dc:contributor> <dc:creator>Zimmermann, Wolfgang</dc:creator> <dc:contributor>Hentschel, Jochen</dc:contributor> <dc:creator>Muenzner, Petra</dc:creator> <dc:creator>Bachmann, Verena</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-06-21T09:12:26Z</dcterms:available> <dc:contributor>Muenzner, Petra</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-06-21T09:12:26Z</dc:date> <dc:contributor>Bachmann, Verena</dc:contributor> <dcterms:title>Human-Restricted Bacterial Pathogens Block Shedding of Epithelial Cells by Stimulating Integrin Activation</dcterms:title> <dcterms:bibliographicCitation>First publ. in: Science 329 (2010), 5996, pp. 1197-1201</dcterms:bibliographicCitation> <dc:creator>Hentschel, Jochen</dc:creator> <dc:creator>Hauck, Christof</dc:creator> <dcterms:issued>2010</dcterms:issued> </rdf:Description> </rdf:RDF>
