Background: There are several evidences that genetic factors besides environmental triggers have important role in initiating the rheumatoid arthritis (RA). The aim of this study was to investigate the association of rheumatoid arthritis with different subtypes of HLA DR4 in Iranian patients. Methods: In an un-matched case control study, 110 rheumatoid arthritis patients (case) and 56 knee ost...
BACKGROUND AND OBJECTIVE Dried blood spot (DBS) sampling has gained wide interest in bioanalysis during the last decade and has already been successfully applied in pharmacokinetic and phenotyping studies. However, all of the available phenotyping studies used small datasets and did not include a systematic evaluation of DBS-specific parameters. The latter is important since several of these fa...
� زمینه و هدف : بیماری سلیاک بیماری گوارشی است که عوامل ژنتیکی در بروز آن دخیل می&rlmباشند. مطالعه حاضر با هدف تعیین HLA DQ2 و HLADQ8 در بیماران با سرولوژی مثبت سلیاک تشخیص داده شده در بین بیماران مبتلا به سندرم روده تحریک پذیر انجام گرفت. � روش کار: این مطالعه توصیفی تحلیلی مقطعی بر روی 105 بیمار مبتلا به سندرم روده تحریک پذیر مراجعه کننده به درمانگاه گوارش مرکز آموزشی درمانی امام خمینی اردبیل...
A random sample of 500 healthy unrelated subjects from Esfahan province were HLA typed for A, 8 and C locus antigens. The lymphocytes were separated from 5 ml of whole peripheral blood and were typed for HLA _ A, 8 and C by using the standard two stage microlymphocytotoxicity NIH technique. The findings suggest that in the study population, frequency of HLA-Al' A2, A3, Ag HLA-8s, 83S and HLA-CW...
EuroPhenome (http://www.europhenome.org) and EMPReSS (http://empress.har.mrc.ac.uk/) form an integrated resource to provide access to data and procedures for mouse phenotyping. EMPReSS describes 96 Standard Operating Procedures for mouse phenotyping. EuroPhenome contains data resulting from carrying out EMPReSS protocols on four inbred laboratory mouse strains. As well as web interfaces, both r...
مقدمه: آنتی ژن های لکوسیتی انسان 1 (HLA) به دلیل وجود ارتباط بین برخی آلل های HLA با بیماریهای مختلف، در ارزیابی استعداد ابتلا به بیماریها و کمک به تشخیص آنها اهمیت دارند. بر اساس بسیاری از تحقیقات انجام شده در سراسر دنیا، قویترین این ارتباطات بین آنتی ژن HLA-B27 و اسپوندیلوآرتروپاتیها، بخصوص اسپوندیلیت آنکیلوزانت (جمود التهابی مهره های کمری ستون فقرات)، وجود دارد. هدف از این تحقیق...
Background: HLA-G gene contains 15 alleles including a null allele, HLA-G*0105N. Previous studies have shown that HLA-G*0105N does not encode the complete HLA-G1 or HLA-G5 isoforms but encodes a functional HLA-G protein with the ability to in-hibit NK cell cytolysis. Thus, although the biological functions of HLA-G1 and HLA-G5 proteins are abrogated, other isoforms such as HLA-G2 can replace th...
Abstract Background and Objectives Histocompatibility antigens (HLAs) have high genetic diversity and their frequency can be diverse in different ethnicities. Therefore, the determination of these antigens in different ethnicities can provide data used in the expansion of centers for the registration of stem cell donors. Materials and Methods In this descriptive study, donor DNA was extracted ...
Abstract Rationale: Increases in the number and size of lymphoid follicles (LFs) are present severe stages COPD have not been fully characterized. HLA complex is crucial enabling immune system to recognize “self” versus “non-self” antigens plays a major role responses cigarette smoke exposure. Methods: Lung from patients with milder (GOLD I–II) more III–IV) were sampled using GeoMX® Digital Spa...
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...
