Background: Human leukocyte antigens (HLAs) are found to be significant genetic factors concerning the susceptibility of an individual to certain diseases. Objective: To determine the association between variants of class I (A and B) and class II (DRB1) HLA alleles and chronic renal failure (CRF), compared with healthy controls, in Yemen. Methods: A case-control study in the Urology and Nephrol...

background: human leukocyte antigens (hla) are polymorphic cell surface proteins. distribution of hla alleles vary among different racial and ethnic populations in unrelated stem cell registries. determination of hla allele frequencies in different ethnic groups is useful for population genetic analyses. materials and methods: based on data available from the iranian stem cell donor registry, h...

Abstract Sensitization to nickel (Ni2+) is the most common T cell mediated type IV hypersensitivity, although mechanisms by which Ni2+ alters antigen presentation are not understood. To study how TCR then recognizes bound MHC molecule, we performed paired single RNA sequencing of PBMCs from two highly sensitized subjects orthopedic implants and characterized three specific CD4+ clones. One rest...

asthma is a complex and multifactorial disorder. several studies have reported association between different hla- dqb1 and hla- drb1 alleles and allergic asthma. the aim of the present study was to investigate the association of hla-class ii alleles and haplotypes, with total serum ige and the results of the skin prick test in iranian children with allergic asthma. a total of 112 patients with ...

selective iga deficiency (igad) (serum iga concentration of pcr was used to type hla b, dr, and dq alleles in 29 iranian individuals with igad and 299 swedish individuals with igad. the results indicate a strong association with the hla b14, dr1 alleles in iranian subjects and hla b8, b12, b13, b14, b40, dr1, dr3, dr7, dq2 and dq5 alleles in swedish subjects. differences in hla association of i...

BackgroundIn patients with idiopathic inflammatory myopathies (IIM), autoantibodies are associated specific clinical phenotypes suggesting a pathogenic role of adaptive immunity. We explored if autoantibody profiles HLA genetic variants and manifestations in IIM.MethodsWe included 1348 IIM determined the occurrence 14 myositis-specific or –associated autoantibodies. used unsupervised cluster an...

Pemphigus vulgaris (PV) is an acquired autoimmune blistering disease characterized by the production of autoantibodies targeting desmosomal cadherins, primarily desmoglein 1 and 3, leading to acantholysis. The etiology PV multifactorial, including genetic susceptibility. This retrospective study aimed evaluate association HLA class II alleles examine impact PV-associated on concentration anti-d...

background: hla compatibility between transplant donor and recipient is one of the major determinants of transplant outcome. objective: to determine hla class i by pcr- sequence-specific oligonucleotide probe (pcr-ssop) in cord blood donors. methods: genomic dna of 142 cord blood samples registered at the cord blood bank of iran at hematology, oncology, and bone marrow transplantation research ...

objective: type 1 diabetes mellitus (t1d) is an autoimmune and multifactorial disorder. subsequent analysis on human leukocyte antigen ( hla) region shows that hla-drb1 and -dqb1 genes have the strongest association with t1d. in this study, for the first time, we investigated the influence of gender on the hla-drb1 and -dqb1 association with type 1 diabetes mellitus in iranian patients in order...

introduction: human leukocyte antigen (hla) genes are the most polymorphic loci in the human genome. they predict the outcome of transplantation by detecting self from non-self antigens. the best use of hla typing is to find a hla-match donor for bmt candidate patients. evidence suggests that matching unrelated donors and recipients for hla-a, -b and -drb1 loci is a prediction for an improved o...
