The risk of celiac disease is strongly associated with human leukocyte | The risk of celiac disease is strongly associated with human leukocyte antigen (HLA) DQ2 and to a lesser extent with HLA DQ8. Although the pathogenesis of HLA-DQ2-mediated celiac disease is established, the underlying basis for HLA-DQ8-mediated celiac disease remains unclear. We showed that T helper 1 (Th1) responses in HLA-DQ8-associated celiac pathology were indeed HLA DQ8 restricted and that multiple, mostly deamidated peptides derived from protease-sensitive sites of gliadin were recognized. This pattern of reactivity contrasted with the more absolute deamidation dependence and relative protease resistance of the dominant gliadin peptide in DQ2-mediated disease. We provided a structural basis for the selection of HLA-DQ8-restricted, deamidated gliadin peptides. The data established that the molecular mechanisms underlying HLA-DQ8-mediated celiac disease differed markedly from the HLA-DQ2-mediated form of the disease. Accordingly, nondietary therapeutic interventions in celiac disease might need to be tailored to the genotype of the individual. | ||
