IgG autoantibodies target the cell adhesion molecules desmoglein (Dsg)3 and plakins, but the nature and targets of infiltrating T cells are poorly characterized. Moreover, the lung involvement in this skin Ag-specific autoimmune condition represents a paradox. To mimic autoimmunity in PNP, we grafted wild-type skin onto Dsg3\u2212\/\u2212 mice, which resulted in graft rejection and generation of anti-Dsg3 IgG and Dsg3-specific T cells. Transfer of splenocytes from these mice into Rag2\u2212\/\u2212 mice induced a combination of suprabasilar acantholysis and interface dermatitis, a histology unique to PNP. Furthermore, the recipient mice showed prominent bronchial inflammation of CD4+ and CD8+ T cells with high mortality. Intriguingly, ectopic Dsg3 expression was observed in the lungs of PNP mice, mirroring the observation that squamous metaplasia is often found in the lungs of PNP patients. Dsg3 and other epidermal Ags were ectopically expressed in the lungs after pulmonary injuries by naphthalene, which was sufficient for recruitment of Dsg3-specific CD4+ T cells. These findings demonstrate that squamous metaplasia after pulmonary epithelial injury may play a crucial role in redirecting the skin-specific autoimmune reaction to the lungs in PNP.<\/jats:p>","DOI":"10.4049\/jimmunol.1203536","type":"journal-article","created":{"date-parts":[[2013,6,1]],"date-time":"2013-06-01T01:15:07Z","timestamp":1370049307000},"page":"83-90","source":"Crossref","is-referenced-by-count":47,"title":["Ectopic Expression of Epidermal Antigens Renders the Lung a Target Organ in Paraneoplastic Pemphigus"],"prefix":"10.1093","volume":"191","author":[{"given":"Tsuyoshi","family":"Hata","sequence":"first","affiliation":[{"name":"Department of Dermatology, Keio University School of Medicine , Tokyo 160-8582,","place":["Japan"]},{"name":"Cutaneous Research Section, Fundamental Research Laboratories, KOS\u00c9 Corporation , Tokyo 174-0051,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuhei","family":"Nishimoto","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Keio University School of Medicine , Tokyo 160-8582,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keisuke","family":"Nagao","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Keio University School of Medicine , Tokyo 160-8582,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hayato","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Keio University School of Medicine , Tokyo 160-8582,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazue","family":"Yoshida","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Keio University School of Medicine , Tokyo 160-8582,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manabu","family":"Ohyama","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Keio University School of Medicine , Tokyo 160-8582,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taketo","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Pathology, Keio University School of Medicine , Tokyo 160-8582,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koichiro","family":"Asano","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, Keio University School of Medicine , Tokyo 160-8582,","place":["Japan"]},{"name":"Division of Pulmonary Medicine, Department of Medicine, Tokai University School of Medicine , Kanagawa 259-1193,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masayuki","family":"Amagai","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Keio University School of Medicine , Tokyo 160-8582,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2013,7,1]]},"reference":[{"key":"2025032405021292500_r1","first-page":"417","volume-title":"Dermatology.","author":"Amagai","year":"2008"},{"key":"2025032405021292500_r2","doi-asserted-by":"crossref","first-page":"869","DOI":"10.1016\/0092-8674(91)90360-B","article-title":"Autoantibodies against a novel epithelial cadherin in pemphigus vulgaris, a disease of cell adhesion","volume":"67","author":"Amagai","year":"1991","journal-title":"Cell"},{"key":"2025032405021292500_r3","doi-asserted-by":"crossref","first-page":"271","DOI":"10.1038\/nrm1356","article-title":"Working out the strength and flexibility of desmosomes","volume":"5","author":"Getsios","year":"2004","journal-title":"Nat.
