In this study, we provide evidence that PV\u2013immunoglobulin G (IgG) and PF-IgG induce skin blistering by interference with Rho A signaling. In vitro, pemphigus IgG caused typical hallmarks of pemphigus pathogenesis such as epidermal blistering in human skin, cell dissociation, and loss of desmoglein 1 (Dsg 1)\u2013mediated binding probed by laser tweezers. These changes were accompanied by interference with Rho A activation and reduction of Rho A activity. Pemphigus IgG\u2013triggered keratinocyte dissociation and Rho A inactivation were p38 mitogen-activated protein kinase dependent. Specific activation of Rho A by cytotoxic necrotizing factor-y abolished all pemphigus-triggered effects, including keratin retraction and release of Dsg 3 from the cytoskeleton. These data demonstrate that Rho A is involved in the regulation of desmosomal adhesion, at least in part by maintaining the cytoskeletal anchorage of desmosomal proteins. This may open the possibility of pemphigus treatment with the epidermal application of Rho A agonists.<\/jats:p>","DOI":"10.1083\/jcb.200605125","type":"journal-article","created":{"date-parts":[[2006,11,27]],"date-time":"2006-11-27T22:38:48Z","timestamp":1164667128000},"page":"721-727","update-policy":"https:\/\/doi.org\/10.1083\/jcb.crossmarkpolicy","source":"Crossref","is-referenced-by-count":140,"title":["Inhibition of Rho A activity causes pemphigus skin blistering"],"prefix":"10.1083","volume":"175","author":[{"given":"Jens","family":"Waschke","sequence":"first","affiliation":[{"name":"1Institute of Anatomy and Cell Biology, University of Wu\u0308rzburg, D-97070 Wu\u0308rzburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Volker","family":"Spindler","sequence":"additional","affiliation":[{"name":"1Institute of Anatomy and Cell Biology, University of Wu\u0308rzburg, D-97070 Wu\u0308rzburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paola","family":"Bruggeman","sequence":"additional","affiliation":[{"name":"1Institute of Anatomy and Cell Biology, University of Wu\u0308rzburg, D-97070 Wu\u0308rzburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Detlef","family":"Zillikens","sequence":"additional","affiliation":[{"name":"2Department of Dermatology, University of Lu\u0308beck, D-23538 Luebeck, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gudula","family":"Schmidt","sequence":"additional","affiliation":[{"name":"3Department of Pharmacology and Toxicology, University of Freiburg, D-79104 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Detlev","family":"Drenckhahn","sequence":"additional","affiliation":[{"name":"1Institute of Anatomy and Cell Biology, University of Wu\u0308rzburg, D-97070 Wu\u0308rzburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"291","published-online":{"date-parts":[[2006,11,27]]},"reference":[{"key":"2023072907553268800_BIB1","doi-asserted-by":"crossref","first-page":"869","DOI":"10.1016\/0092-8674(91)90360-B","volume":"67","year":"1991","journal-title":"Cell."},{"key":"2023072907553268800_BIB2","doi-asserted-by":"crossref","first-page":"895","DOI":"10.1111\/1523-1747.ep12606168","volume":"104","year":"1995","journal-title":"J.
