HLA-DQ structural polymorphism in HLA-DR2 associated HLA-D clusters
Human Immunology, 1986Three homozygous cell lines with different cellular HLA-D specificities associated with HLA-DR2 including Dw2, Dw12, DB9 displayed structural variation in the products of the DQ locus. Nonglycosylated precursor polypeptides of DQ molecules immunoprecipitated by two-dimensional polyacrylamide gel electrophoresis (2-D gel) revealed distinct differences ...

Tissue Antigens, 1998
Abstract: Nine novel HLA‐A and HLA‐B alleles are described: A*2609, A*6803, A*6806, B*1539, B*1540, B*2712, B*4103, B*5109, and B*5603. Most appear to have arisen by gene conversion events. B*5603 appears to have arisen by a reciprocal recombination event joining exon 2 of a B*55/*56 allele with exon 3 of a B*15 allele.

Association of HLA‐DRBr with HLA‐DQw3
Tissue Antigens, 1988The antigen HLA‐DRBr, previously associated with HLA‐DQw1, has been found by RFLP to be associated with HLA‐DQw3.

Antigen Report: HLA-Bw70, HLA-Bw71, and HLA-Bw72
1984The antigens Bu (= Bw71) and SV (= Bw72) were originally identified in 1977 in English and Dutch populations [1, 2]. Both were recognised as low-frequency Bw6-associated antigens included in the tail of some multispecific sera defining the B5, 35, 18, 15, 21 (7b) cross-reactive group. A two-centre collaborative study established that Bu and SV were two

Association of HLA-Ib (HLA-G, HLA-E and HLA-F) with spontaneous HBV clearance
Infectious DiseasesThe natural history of HBV infection is highly heterogeneous. Failure to clear the virus during the acute phase of infection allows for viral persistence and progression to chronicity. Investigating the immune mechanisms involved in this process is crucial for effectively managing infection outcome.

Both HLA-DR and HLA-DQ determinants contribute to HLA-Dw typing
Human Immunology, 1987The respective contribution of HLA-DR and HLA-DQ gene products in the induction of allogeneic proliferative responses in primary mixed lymphocyte reaction and, therefore, in HLA-Dw typing, is still unclear or controversial. This is in part due to a strong linkage disequilibrium between HLA-DR and -DQ genes.
