HLA antibodies usually recognize epitopes rather than antigens. This case report reveals that acute antibody-mediated rejection (AMR) that occurred in a kidney transplant recipient with low-level donor-specific antibodies (DSAs) could be explained by shared epitope. A 39-year-old woman received a first kidney transplant from a deceased donor (HLA-DRB1 11:06, 12:02, DRB3 02:02, 03:01). She devel...
BACKGROUND Sarcoidosis is a systemic disease of unknown aetiology frequently affecting the lungs. CD4+ T cells, in particular, accumulate in the lungs, implicating them in the pathogenesis of the disease. METHODS T cell receptor (TCR) variable (V) gene expression on bronchoalveolar lavage (BAL) fluid T cells and the HLA DR alleles of 121 Scandinavian patients with sarcoidosis was determined. ...
background: major histocompatibility complex (mhc) comprises a group of genes, which plays a central role in immune response. the exon 2 of bula-drb3 is part of the mhc class ii in buffalo that highly polymorphic, found to be associated with resistance/susceptibility to infections and also with production parameters. objectives: the purpose of the present study is to identify bula-drb3 polymorp...
زمینه مطالعه: مجتمع اصلی سازگاری نسجی (MHC) شامل گروهی از ژن‌ها است که نقش مهمی در پاسخ‌های ایمنی دارند. اگزون 2 از ژن BuLA-DRB3 بخشی از MHC کلاس 2 در گاومیش است که تنوع بسیار بالایی داشته و آلل‌های آن با مقاومت/حساسیت به بیماریها و همچنین با خصوصیات تولیدی مرتبط هستند. هدف: شناسایی تنوع ژن BuLA-DRB3 در گاومیش‌های خوزستان و مقایسه آن با سایر جمعیت‌های گاومیش ایران و جهان. روش کار: نمونه‌های ...
HLA class II loci are useful markers in human population genetics, because they are extremely variable and because new molecular techniques allow large-scale analysis of DNA allele frequencies. Direct DNA typing by hybridization with sequence-specific oligonucleotide probes (HLA oligotyping) after enzymatic in vitro PCR amplification detects HLA allelic polymorphisms for all class II loci. A de...
We have updated the catalogue of common and well-documented (CWD) human leukocyte antigen (HLA) alleles to reflect current understanding of the prevalence of specific allele sequences. The original CWD catalogue designated 721 alleles at the HLA-A, -B, -C, -DRB1, -DRB3/4/5, -DQA1, -DQB1, and -DPB1 loci in IMGT (IMmunoGeneTics)/HLA Database release 2.15.0 as being CWD. The updated CWD catalogue ...
A single mismatch in highly expressed HLA-A, -B, -C, and -DRB1 loci (HEL) is associated with worse outcomes in hematopoietic stem cell transplantation, while less is known about the cumulative impact of mismatches in the lesser expressed HLA loci DRB3/4/5, DQ, and DP (LEL). We studied whether accumulation of LEL mismatches is associated with deleterious effects in 3853 unrelated donor transplan...
بز سرخ جبال بارز با جمعیتی بالغ بر 450 هزار رأس در منطقه جیرفت و کهنوج پرورش می یابد و با تولید کرک، گوشت قرمز و محصولات لبنی از منابع درآمد مهم عشایر و دامداران محسوب می شود. در این پژوهش که به منظور بررسی چند شکلی ژن gola-drb3 با استفاده از pcr-reflp در این دام ها صورت گرفت از 100 بز به صورت تصادفی و انفرادی خونگیری شد. سپس dna نمونه های خون دامها با استفاده از کیت استاندارد استخراج و تعیین ...
BACKGROUND Although inflammation in Crohn's disease is believed to be mediated by activated T cells, genotyping of all MHC class II alleles in white people with this disease has not been reported. AIMS To perform a detailed molecular analysis of HLA DPB, DQB, and DRB genes in white patients with Crohn's disease and controls in order to determine if the inheritance of any class II genes confer...
In previous reports of studies of Scandinavian sarcoidosis patients, we have described a strong association between lung-restricted expansions of T cells expressing T-cell receptor (TCR) AV2S3 and the human leukocyte antigen (HLA)-DRB1*0301 (DR17) and -DRB3*0101 alleles, suggesting the presence of a specific antigen in sarcoidosis. In the present study, the degree of lung-accumulated TCR AV2S3(...
