A structural and immunological basis for the role of human leukocyte antigen DQ8 in celiac disease.

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.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
