OBJECTIVE To study the influence MHC class II and TAP2 alleles exert on systemic lupus erythematosus (SLE) susceptibility and on the clinical and serological manifestations of the disease, in a cohort of Spanish patients. METHODS HLA-DR serological typing and HLA-DQA, DQB, and TAP2 DNA sequence specific oligotyping, were carried out in 85 unrelated Spanish SLE patients and 186 healthy control...
Coeliac disease is an inflammation of the small intestine, occurring in genetically susceptible individuals triggered by the ingestion of gluten. Human Leukocyte Antigens (HLA) DQ2 and DQ8 gene have been identified as key genetic factors in coeliac disease as they are presented in almost 100 % of the patients. These genes are encoded by the combination of certain alleles in the DQA and DQB regi...
OBJECTIVE The unfolding of type 1 diabetes involves a number of steps: defective immunological tolerance, priming of anti-islet autoimmunity, and destruction of insulin-producing beta-cells. A number of genetic loci contribute to susceptibility to type 1 diabetes, but it is unclear which stages of the disease are influenced by the different loci. Here, we analyzed the frequency of type 1 diabet...
Drug-induced idiosyncratic liver disease (DIILD) depends largely on host susceptibility factors. Small studies support the genetic influence of human leukocyte antigen (HLA) class II molecules on the predisposition to DIILD. We sought associations between HLA-DRB and -DQB alleles and DIILD considered collectively or according to the biochemical expression of liver damage. We studied a total of ...
DNA from 164 Caucasian type I (insulin-dependent) diabetic patients and 200 Caucasian nondiabetic control blood donors were analyzed by the polymerase chain reaction technique for HLA-DR4 and the associated Dw and DQB subtypes of DR4. The DQw8 subtype of HLA-DR4 was associated with type I diabetes in all DR4 subgroups (DR4/3 and DR4/non-3). Dw subtypes of DR4 other than DW10 did not confer addi...
OBJECTIVE To study the role of the HLA system in the genetic susceptibility to familial systemic sclerosis (SSc). METHODS HLA class I antigens were determined by classic serological methods and HLA-DRB, -DQA and -DQB genes were analysed by genetic typing in 36 individuals belonging to two families with several individuals affected by SSc. RESULTS The results did not show any association of ...
A partial 517 nucleotide long DQB cDNA was amplified and sequenced from water buffalo (Bubalus bubalis) and was named as Bubu-DQB*2. The Bubu-DQB*2 showed 96.6% and 92% homologies with cattle (BoLA)-DQB2 and -DQB1 sequences, respectively, whereas 95.6, 96, 90.3, 86 and 90% homologies with sheep, goat, pig, dog and human, respectively. The Bubu-DQB*2 showed 20 nucleotide changes including eight ...
The work was done to study immunogenetic peculiarities of neuroinflammatory diseases among Korean children. A total of 13 children with neuroinflammatory diseases (8 males and 5 females; mean age 4.6 +/-2.6 yr) were consecutively recruited. Geno-mic typing was performed on their HLA DRB/HLA DQB genes using PCR-SSOP/SSP techniques with gel immunoelectrophoresis. The frequencies of HLA-DR1 *15 in...
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...
