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)...
چکید ه سابقه و هدف با توجه به تاسیس مرکز پذیرش اهداکنندگان سلول‌های بنیادی خونساز در سازمان انتقال خون ایران (مرکز سپاس) در سال 1387, بر آن شدیم به بررسی آنتی‌ژن‌های سازگاری بافتی داوطلبان اهدای این سلول‌ها از قومیت‌های حاضر در شهر تهران طی سال 91-90 بپردازیم. مواد و روش‌ها در یک مطالعه توصیفی، 1513 نفر از افراد داوطلب عضو مرکز سپاس در محدوده سنی 18 تا 50 سال و با سابقه یک بار اهدای خ...
Background: Non-Hodgkin lymphoma (NHL) includes a wide range of diseases with different clinical and biological features. NHL is usually presented as localized or generalized lymphadenopathy. It has been suggested that the HLA class I and II are associated with susceptibility to NHL. Different ethnic groups have been found to have different HLA class I and II alleles which affect NHL. Objective...
The association of HLA and disease varies in different populations. We have . studied the association of HLA class I in Iranian psoriatic patients, in order to compare this association with other reports. Fifty-one Iranian patients with psoriasis were HLA typed. The frequency of HLA antigens in patients and patient subgroups, based on clinical patterns, age of onset, family history and prov...
Background: Human leukocyte antigen (HLA) class II has shown potential in determining prognosis, understanding medication reactions, and predicting onset of Graves’ disease. The aim this study is to further investigate the association between disease HLA II, specifically HLA-DQ HLA-DR, via meta-analysis find HLAs that can be examined for prognostic reasons.
Gene variants derived from Neanderthals or Denisovans can be associated with polygenic traits, validating the utility of notion about archaic gene flow. Endoplasmic reticulum aminopeptidase 1 (ERAP1) haplotypes control disease risk primarily mediated by HLA-C*06:02, HLA-B*27 and HLA-B*51 for psoriasis, ankylosing spondylitis (AS) Behçet's (BD). In this genetic interaction corresponds to differe...
Abstract Sensitization to nickel (Ni2+) is the most common T cell mediated type IV hypersensitivity, although mechanisms by which Ni2+ alters antigen presentation are not understood. To study how TCR then recognizes bound MHC molecule, we performed paired single RNA sequencing of PBMCs from two highly sensitized subjects orthopedic implants and characterized three specific CD4+ clones. One rest...
Background: HLA compatibility between transplant donor and recipient is one of the major determinants of transplant outcome. Objective: To determine HLA class I by PCR- Sequence-Specific Oligonucleotide Probe (PCR-SSOP) in cord blood donors. Methods: Genomic DNA of 142 cord blood samples registered at the Cord Blood Bank of Iran at Hematology, Oncology, and Bone Marrow Transplantation Researc...
مالتیپل اسکلروزیس (ms)یک بیماری التهابی سیستم اعصاب مرکزی است که از تعامل پیچیده فاکتورهای ژنتیکی و عوامل محیطی منشاء می گیرد. براساس مطالعات گسترده ژنومی (gwas) چندین پلی مورفیسم تک نوکلئوتیدی (snp) در ژن های مسئول عملکرد ایمنی به عنوان عوامل مستعد کننده بیماری شناخته شده اند. از طرف دیگربا توجه به اهمیت shla-g به عنوان یکی از فاکتورهای تعدیل کننده ایمنی و نقش حیاتی سلول های t تنظیمی در بیماری...
Psoriasis (PsO) is a T cell-mediated autoimmune disease without cure. The major risk-associated PsO susceptibility gene encodes for the human leukocyte antigen C*06:02 (HLA-Cw6). Half of patients carry this allele encoding HLA-I molecule which presents short peptides (together known as immunopeptidome) to CD8 cells, thereby initiating immune responses. It unclear presented by HLA-Cw6 are preval...
