We proposed to explore the pathogenesis of these oral defects, which are poorly studied. Sequence analyses of proteins from gluten (gliadins) and of proline\u2010rich enamel proteins (amelogenin and ameloblastin) suggested the presence of common antigenic motifs. Therefore, we analyzed, by ELISA and western blotting, the reactivity of sera from patients with CD against gliadin and enamel\u2010derived peptides. Correlation analyses between the levels of specific antibodies against gliadin and enamel derived peptides and inhibition experiments confirmed the presence of cross\u2010reactive antibodies. Immunoblot analysis revealed that the most prominent component in enamel matrix derivative (of approximately 18.6\u2003kDa), identified by an amelogenin\u2010specific antibody, is recognized by sera from patients with CD; in addition, several fractions of pure gliadin were recognized by amelogenin\u2010specific antibody. In agreement, sera from mice immunized with enamel matrix\u2010derived proteins generated antibodies that recognized a peptide (of approximately 21.2\u2003kDa) derived from gliadin. In conclusion, antibodies against gliadin generated in patients with CD can react <jats:italic>in vitro<\/jats:italic> with a major enamel protein. The involvement of anti\u2010gliadin serum in the pathogenesis of enamel defects in children with untreated CD can be hypothesized on the basis of these novel results.<\/jats:p>","DOI":"10.1111\/j.1600-0722.2012.00949.x","type":"journal-article","created":{"date-parts":[[2012,3,12]],"date-time":"2012-03-12T14:59:05Z","timestamp":1331564345000},"page":"104-112","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Enamel
