KRT1 mutations cause epidermolytic ichthyosis in humans, characterized by loss of barrier integrity and recurrent erythema. In search of the largely unknown pathomechanisms and the role of keratins in barrier formation and inflammation control, we show here that Krt1 is crucial for maintenance of skin integrity and participates in an inflammatory network in murine keratinocytes. Absence of Krt1 caused a prenatal increase in interleukin-18 (IL-18) and S100A8\/A9, accompanied by a barrier defect and perinatal lethality. Depletion of IL-18 partially rescued Krt1\u2212\/\u2212 mice. IL-18 release was keratinocyte-autonomous, KRT1- and caspase-1-dependent, supporting an upstream role of KRT1 in the pathology. Finally, transcriptome profiling revealed a Krt1-mediated gene expression signature similar to atopic eczema (AE) and psoriasis, but different from Krt5-deficiency and epidermolysis bullosa simplex (EBS). Our data suggest a functional link between KRT1 and human inflammatory skin diseases.<\/jats:p>","DOI":"10.1242\/jcs.116574","type":"journal-article","created":{"date-parts":[[2012,11,7]],"date-time":"2012-11-07T17:39:23Z","timestamp":1352309963000},"source":"Crossref","is-referenced-by-count":103,"title":["Keratin 1 maintains skin integrity and participates in an inflammatory network in skin\n                    <i>via<\/i>\n                    interleukin-18"],"prefix":"10.1242","author":[{"given":"Wera","family":"Roth","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vinod","family":"Kumar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans-Dietmar","family":"Beer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miriam","family":"Richter","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Wohlenberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ursula","family":"Reuter","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00f6ren","family":"Thiering","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Staratschek-Jox","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Hofmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatima","family":"Kreusch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joachim L","family":"Schultze","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Vogl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes","family":"Roth","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ingrid","family":"Hausser","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas M","family":"Magin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","published-online":{"date-parts":[[2012,1,1]]},"reference":[{"key":"2021042522011486100_b1","doi-asserted-by":"publisher","first-page":"1365","DOI":"10.1111\/j.1365-2133.2010.09657.x","article-title":"Identification of novel and known KRT5 and KRT14 mutations in 53 patients with epidermolysis bullosa simplex: correlation between genotype and phenotype.","volume":"162","author":"Arin","year":"2010","journal-title":"Br.
