BACKGROUND AND OBJECTIVE Risk haplotypes have been described in celiac disease (CD), but the influence of native genes on CD in Hispanic Americans is unknown. The aim of the study was to measure the frequency of Amerindian mitochondrial DNA (mtDNA) haplogroups (inherited by the maternal line) in mixed-blood patients with CD from Chile, Argentina, and Uruguay, and to assess the relation between ...
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...
زمینه و هدف: مولتیپل اسکلروزیس یک بیماری خود ایمن با اتیولوژی نامشخص می باشد. فاکتورهای محیطی و ژنتیکی در استعداد ابتلا به بیماری نقش دارند. مطالعات ژنتیکی نشان می دهد که ژنهای کد کننده آنتی ژن های سازگار نسجی (hla) با بروز برخی از بیماری های خود ایمن از جمله مولتیپل اسکلروزیس ارتباط دارند. مطالعات انجام شده نشان می دهد که در جوامع مختلف بین همراهی این ژن ها و بیماری مغایرت وجود دارد. با توجه ب...
OBJECTIVE The Israeli Yemenite Jewish community has displayed an exceptionally rapid increase in the frequency of type 1 diabetes, having the highest rate of all Israeli ethnic groups. We studied the role of the environment, in relation to the nature and frequency of HLA class II genes, to evaluate its possible involvement in the development of diabetes. RESEARCH DESIGN AND METHODS We intervi...
BACKGROUND Human leukocyte antigen (HLA)-DQ has emerged as the alloantibody most frequently associated with the generation of de novo donor-specific antibody (DSA), antibody-mediated-rejection, and unfavorable transplantation outcome. METHODS The generation of HLA-DQ de novo DSA was interrogated in 40 transplant recipients who were immunologically naive before their failed transplantation. Ep...
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...
The present study demonstrated genetic analysis of human leukocyte antigen (HLA) in a familial Graves' disease linked to autoimmune mechanism. The proband was a 17 year-old female. At 15 years, Graves' disease was diagnosed with serum TSH was <0.015 IU/ml; free T(3), 13.6 pg/ml; free T(4), 4.51 ng/dl; and TSH receptor antibody (TRAb), 94.1%. She had two brothers (19 and 13 years-old), who manif...
همانطور که می دانیم، پلی آمیدها و پلی ایمیدهای و پلی(آمید-ایمید)های آروماتیک میله ای سخت، بخاطر خواص مکانیکی و حرارتی و همچنین خواص ریخت شناسی منحصربه فرد، بسیار مورد توجه قرار گرفته اند. بهرحال بخاطر نامحلول بودن در حلالهای آلی و همچنین نقطه ذوب و دمای تبدیل شیشه ای بالا، فرایندپذیری این مواد مشکل می باشد. قسمتی از این مسئله مربوط به پیوندهای هیدروژنی قوی و برهمکنشهای دهنده/گیرنده گروههای آمید...
Although many studies have analyzed HLA allele frequencies in several ethnic groups in patients with scleroderma (SSc), none has been done in French Caucasian patients and none has evaluated which one of the common amino acid sequences, (67)FLEDR(71), shared by HLA-DRB susceptibility alleles, or (71)TRAELDT(77), shared by HLA-DQB1 susceptibility alleles in SSc, was the most important to develop...
Celiac disease is strongly associated with the HLA class II D-region serologic markers DR3 (DRw17) and DQw2. Moreover, by restriction fragment length polymorphism analysis, greater than 90% of DR3 (DRw17), DQw2 celiac disease patients have a polymorphic 4.0-kilobase Rsa I DP B gene DNA fragment. The present study sought to determine if there is a unique HLA class II D-region A or B gene structu...
