Objective: This study aimed to investigate the association between HLA alleles and visceral leishmaniasis (VL) in a sample of Iraqi patients. Methods: A total of 30 patients were studied, in addition to 20 age, gender and ethnicity matched controls. All subjects were genotyped by polymerase chain reaction-sequence specific primers (PCR-SSP) method. Results: For HLA-class I region (A and B loci)...
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...
� 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...
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...
HLA-G is a nonclassical HLA class Ib, which is located on chromosome 6 (6p.21.3). In contrast to HLA class I molecules, HLA-G has restricted polymorphism. Expression of this molecule in the physiological conditions limits to certain tissues such as thymus, cornea, nail matrix, trophoblast and pancreas. Up to now, 50 alleles of HLA-G molecules have been discovered with 16 distinct functional pro...
