Little is known about the major histocompatibility complex (MHC) in the genome of Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) (YFP) or other cetaceans. In this study, a high-quality YFP bacterial artificial chromosome (BAC) library was constructed. We then determined the organization and characterization of YFP MHC class II region by screening the BAC library, followe...
In traditional Chinese medicine (TCM), correct syndrome differentiation is the most important principle guiding the prescription of Chinese herbal formulae for the treatment of gastric cancer (GC). We aimed to reveal the genetic mechanisms underlying GC syndrome differentiation (ZHENG) in a population of 387 GC patients. Twenty-nine single nucleotide polymorphisms (SNPs) in EGF, TGFA, and EGFR ...
The MHC of cattle encodes two distinct isotypes of class II molecules, DR and DQ. Unlike humans, cattle lack the DP locus and about half the common haplotypes express duplicated DQ genes. The number and frequency of DQA and DQB alleles means that most cattle are heterozygous. If inter- and/or intrahaplotype pairing of DQA and DQB molecules occurs, cattle carrying DQ-duplicated haplotypes may ex...
The major histocompatibility complex (MHC) is central to maintaining the immunologic vigor of individuals and populations. Classical MHC class II genes were targeted for partial sequencing in sea otters (Enhydra lutris) from populations in California, Washington, and Alaska. Sequences derived from sea otter peripheral blood leukocyte mRNAs were similar to those classified as DQA, DQB, DRA, and ...
Jejunal biopsy specimens from 25 patients with IgA deficiency (IgAd) were studied immunohistochemically to find markers of inflammation. Five of the 25 patients had coeliac disease (CD): they were on a gluten free diet and had normal jejunal morphology. Only two of 15 specimens from control subjects had CD25+ cells in the surface epithelium, while this was seen in 19 out of 20 specimens from Ig...
مقدمه :یکی از انواع شایع آلرژی رینیت آلرژی است .عامل اصلی این نوع آلرژی گرده گل ها، درختان و علف های هرز است .این گیاهان به طور عمده در بهار و تابستان گرده افشانی می کنند . یکی از این گیاهان آرتمیسیا ولگاریس است که در اواخر تابستان گرده افشانی می کند و از شیوع با?یی در سراسر جهان از جمله ایران برخوردار است . ارتباط مهمی بین آلل های hla-drb1 و آلرژی به گیاه آرتمیسیا ولگاریس در شهرستان سبزوار واق...
Background: HLA disease association was investigated in several autoimmune, cancer and infectious diseases. The outcome of tuberculosis (TB) infection may be influenced by host genetic factors like MMP-1, MCP-1, IL-10, IL-12, TNF-α, IFN-γ and human leukocyte antigen (HLA). Given the paucity of information with regard to the association between the human leukocyte antigens (HLA) and TB infection...
OBJECTIVE The Type 1 Diabetes Genetics Consortium has collected type 1 diabetic families worldwide for genetic analysis. The major genetic determinants of type 1 diabetes are alleles at the HLA-DRB1 and DQB1 loci, with both susceptible and protective DR-DQ haplotypes present in all human populations. The aim of this study is to estimate the risk conferred by specific DR-DQ haplotypes and genoty...
هدف: روماتوئیدآرتریتیس (ra) شایعترین بیماری التهابی مزمن و مخرب مفصلی است که انتشار جهانی دارد و شیوع آن در سطح جهان حدود 5/0 تا 1 درصد می باشد. برای تشخیص قطعی بیماری ra در مراحل اولیه بیماری روش آزمایشگاهی مشخصی موجود نمی باشد و از آنجا که تشخیص سریع آن بسیار حایز اهمیت است، استفاده از روشهای مولکولی می تواند در تشخیص به موقع و دقیق بیماری بسیار مؤثر باشد. با وجود این که هنوز علت اصلی این بیم...
