Endemic pemphigus foliaceus in humans, known as Fogo Selvagem (FS) in Brazil, is mediated by pathogenic IgG4 autoantibodies against desmoglein 1 (Dsg1). Clusters of FS overlap with those of leishmaniasis, a disease transmitted by sand fly (Lutzomyia longipalpis) bites. In this study, we show that salivary Ags from the sand fly, and specifically the LJM11 salivary protein, are recognized by FS Abs. Anti-Dsg1 monoclonal autoantibodies derived from FS patients also cross-react with LJM11. Mice immunized with LJM11 generate anti-Dsg1 Abs. Thus, insect bites may deliver salivary Ags that initiate a cross-reactive IgG4 Ab response in genetically susceptible individuals and lead to subsequent FS. Our findings establish a clear relationship between an environmental, noninfectious Ag and the development of potentially pathogenic autoantibodies in an autoimmune disease.<\/jats:p>","DOI":"10.4049\/jimmunol.1200842","type":"journal-article","created":{"date-parts":[[2012,7,15]],"date-time":"2012-07-15T19:47:41Z","timestamp":1342381661000},"page":"1535-1539","source":"Crossref","is-referenced-by-count":88,"title":["Cutting Edge: Brazilian Pemphigus Foliaceus Anti-Desmoglein 1 Autoantibodies Cross-React with Sand Fly Salivary LJM11 Antigen"],"prefix":"10.1093","volume":"189","author":[{"given":"Ye","family":"Qian","sequence":"first","affiliation":[{"name":"Department of Dermatology, University of North Carolina at Chapel Hill , Chapel Hill, NC 27599"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph S","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of North Carolina at Chapel Hill , Chapel Hill, NC 27599"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mike","family":"Maldonado","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of North Carolina at Chapel Hill , Chapel Hill, NC 27599"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesus G","family":"Valenzuela","sequence":"additional","affiliation":[{"name":"Vector Molecular Biology Section, Laboratory of Malaria and Vector Research, National Institute of Allergy and Infectious Diseases, National Institutes of Health , Rockville, MD 20852"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Regis","family":"Gomes","sequence":"additional","affiliation":[{"name":"Vector Molecular Biology Section, Laboratory of Malaria and Vector Research, National Institute of Allergy and Infectious Diseases, National Institutes of Health , Rockville, MD 20852"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clarissa","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Vector Molecular Biology Section, Laboratory of Malaria and Vector Research, National Institute of Allergy and Infectious Diseases, National Institutes of Health , Rockville, MD 20852"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Flor","family":"Evangelista","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of North Carolina at Chapel Hill , Chapel Hill, NC 27599"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bahjat","family":"Qaqish","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, University of North Carolina at Chapel Hill , NC 27599"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valeria","family":"Aoki","sequence":"additional","affiliation":[{"name":"Departamento de Dermatologia , Universidade de Sao Paulo 01246-903,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr.","given":"Gunter","family":"Hans","sequence":"additional","affiliation":[{"name":"Departamento de Dermatologia, Universidade Federal de Mato Grosso do Sul , Mato Grosso do Sul 79070-900,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evandro A","family":"Rivitti","sequence":"additional","affiliation":[{"name":"Departamento de Dermatologia , Universidade de Sao Paulo 01246-903,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donald","family":"Eaton","sequence":"additional","affiliation":[{"name":"Departamento de Dermatologia, Universidade Federal de Mato Grosso do Sul , Mato Grosso do Sul 79070-900,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis A","family":"Diaz","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of North Carolina at Chapel Hill , Chapel Hill, NC 27599"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2012,8,15]]},"reference":[{"key":"2025032409222833100_r1","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1007\/978-1-4419-8216-2_6","article-title":"Environmental agents and autoimmune diseases","volume":"711","author":"Miller","year":"2011","journal-title":"Adv.
