Biased usage and preferred pairing of α- and β-chains of TCRs specific for an immunodominant gluten epitope in coeliac disease
13 Sept 2013
Abstract excerpt
CD4⁺ T cells that recognize dietary gluten antigens presented by the disease-associated HLA-DQ2 or DQ8 molecules are central players in coeliac disease. Unbiased sequencing of the human TCRα variable (TRAV) and humanTCRβ variable (TRBV) genes of 68 HLA-DQ2.5-glia-α2-specific T cells from coeliac disease patients confirmed previous reports of over-usage of the TRBV7-2 gene segment, a conserved Arg residue in the...
