A central event in celiac disease (CD) is the recognition by TCRs of gluten epitopes presented by specific HLAs, with HLA-DQ2 being associated with 95% of CD cases. The molecular basis for these interactions are now revealed by crystal structures of TCRs from individuals with CD in complex with wheat gliadin epitopes presented by HLA-DQ2.
