Gluten-specific T cells cross-react between HLA-DQ8 and the HLA-DQ2α/DQ8β transdimer.

Because susceptibility to celiac disease is associated strongly with HLA-DQ2 (DQA1*05/DQB1*02) and weakly with HLA-DQ8 (DQA1*03/DQB1*03), a subset of patients carries both HLA-DQ2 and HLA-DQ8. As a result, these patients may express two types of mixed HLA-DQ2/8 transdimers (encoded by DQA1*05/DQB1*03 and DQA1*03/DQB1*02) in addition to HLA-DQ2 and HLA-DQ8. Using T cells from a celiac disease pa...

Recent insight in the pathophysiology of coeliac disease: relevance to rheumatoid arthritis.

Coeliac disease (CD) is a T cell mediated inflammatory disorder of the small intestine that affects approximately 1% of the population (1, 2). CD is triggered by gluten ingestion, proteins found in wheat, barley and rye. CD4(+) T cells specific for post-translationally modified gluten peptides bound to the disease-predisposing HLA-DQ2 or HLADQ8 molecules are typically found in patients with CD,...

Molecular basis of celiac disease.

Celiac disease (CD) is an intestinal disorder with multifactorial etiology. HLA and non-HLA genes together with gluten and possibly additional environmental factors are involved in disease development. Evidence suggests that CD4(+) T cells are central in controlling an immune response to gluten that causes the immunopathology, but the actual mechanisms responsible for the tissue damage are as y...

Determinants of gliadin-specific T cell selection in celiac disease.

In HLA-DQ8-associated celiac disease (CD), the pathogenic T cell response is directed toward an immunodominant α-gliadin-derived peptide (DQ8-glia-α1). However, our knowledge of TCR gene usage within the primary intestinal tissue of HLA-DQ8 (+) CD patients is limited. We identified two populations of HLA-DQ8-glia-α1 tetramer(+) CD4(+) T cells that were essentially undetectable in biopsy samples...

HLA-DQ2 and -DQ8 signatures of gluten T cell epitopes in celiac disease.

Celiac disease is associated with HLA-DQ2 and, to a lesser extent, HLA-DQ8. Type 1 diabetes is associated with the same DQ molecules in the opposite order and with possible involvement of trans-encoded DQ heterodimers. T cells that are reactive with gluten peptides deamidated by transglutaminase 2 and invariably restricted by DQ2 or DQ8 can be isolated from celiac lesions. We used intestinal T ...
