The T-cells are defined by the ability to react to HLA-DQ8 and DQ2.5 restricted antigens and gliadin is one of the antigens. Gliadin is a favored dietary substrate for transglutaminase because of many enzyme reaction sites on gliadin.
HLA-DQ2 (DQ2) is a serotype group within HLA-DQ (DQ) serotyping system. The serotype is determined by the antibody recognition of β 2 subset of DQ β-chains. The β-chain of DQ is encoded by HLA-DQB1 locus and DQ2 are encoded by the HLA-DQB1 *02 allele group. This group currently contains two common alleles, DQB1 *0201 and DQB1 *0202.
HLA A30-Cw5-B18-DR3-DQ2 (A30::DQ2) is a multigene haplotype that extends across a majority of the major histocompatibility complex on human chromosome 6. A multigene haplotype is a set of inherited alleles covering several genes, or gene-alleles. Long haplotypes, like A30::DQ2, are generally the result of descent by common ancestry.
An example of a serotype is DQ2. Recognize HLA-DQB1*02 gene products which include gene products of the following alleles: HLA-DQB1*02:01; HLA-DQB1*02:02; HLA-DQB1*02:03; Sometimes DQ2 antibodies recognize other gene products, such as DQB1*03:03, resulting in serotyping errors. Because of this mistyping serotyping is not as reliable as gene ...
HLA region of Chromosome 6. The human leukocyte antigen (HLA) system is a complex of genes on chromosome 6 in humans that encode cell-surface proteins responsible for regulation of the immune system. [1] The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in many animals. [2]

HLA class I restrictions to gliadin are not well characterized. HLA-A2 presentation has been investigated. The HLA-A antigens can mediate apoptosis in autoimmune disease and HLA A*0201 in with the HLA-DQ8 haplotypes has been documented. [13] The class I sites were found on the carboxyl end of gliadin at positions 123–131, 144–152, and 172 ...
HLA DR3-DQ2 is the serotypic representation of a HLA-DRB1:DQA1:DQB1 cis-chromosomal haplotype on human 6p21.3 in a region known as the HLA complex. The DR3-DQ2 haplotype is notable because of the very strong linkage between genes that extends into the HLA-A , - B and - C regions of the HLA gene complex in northern and northwestern Europe.
