[ 1 ] - HLA Class I and Class II Genes Distribution of the Sistanis in Iran

Background: The high polymorphism in the human leukocyte antigen (HLA) genes can be used as an identity of individuals to compare with other populations. This extreme polymorphism in the HLA system is accountable for the differences in alleles and haplotypes among ethnic groups, populations, and the inhabitants of many regions. Objective: To define the frequency of HLA alleles and haplotypes am...

[ 2 ] - Association of Human Leukocyte Antigens Class I & II with Graves’ Disease in Iranian Population

Background: Graves’ disease (GD), a highly rampant autoimmune disorder of the thyroid gland, is responsible for 60-80% of the clinical cases of hyperthyroidism. Over the past decades, genetic association studies have identified several GD susceptibility loci in CTLA-4, TSHR and major histocompatibility complex regions. The information on the association between the human leukocyte antigens (HLA...

[ 3 ] - Increased Expression of Toll-Like Receptors 2 and 4 in Renal Transplant Recipients that Develop Allograft Dysfunction: A Cohort Study

Background: The incidence of ischemic reperfusion injury (IRI) in early phase post-transplantation and activation of toll-like receptor (TLR-2) and TLR-4 remarkably impact the outcome of a renal allograft. Objective: To investigate whether the expression of TLRs in peripheral blood mononuclear cells (PBMCs) can predict the clinical outcome of kidney allografts. Methods: We obtained blood sample...

[ 4 ] - Effect of TNF-α Blockade in Gingival Crevicular Fluid on Periodontal Condition of Patients with Rheumatoid Arthritis

Background: Periodontitis and rheumatoid arthritis (RA) share a number of clinical and pathologic features, one of which is the presence of the tumor necrosis factor alpha (TNF-α)-induced bone resorption that is involved in the pathogenesis of both. Objectives: To investigate the effect of TNF-α blockade on periodontal conditions in patients with active RA. Method: The periodontal statuses of 3...

[ 5 ] - Reference Values of Lymphocyte Sub-Populations in Healthy Human Immunodeficiency Virus-Negative Iranian Adults

Background: Lymphocyte subsets enumeration is considered prominent in the management of primary and acquired immunodeficiency disorders. Because of local variations due to race, age, gender, and environmental conditions on lymphocyte subsets, and to improve the accuracy of interpretation of laboratory findings, reference intervals must be determined in every population. Objective: To establish ...

[ 6 ] - Regulatory T Cell Subtypes and TGF-β1 Gene Expression in Chronic Allograft Dysfunction

Background: Regulatory T cells have been suggested to have a protective role against acute rejection in allograft recipients. However, there is little information available about their contribution to chronic rejection process. The role of transforming growth factor-beta 1 (TGF- β1) as a profibrogenic and/or immunoregulatory cytokine in renal allografts is also controversial. Objectives: To eva...

[ 7 ] - Association between HLA-DQB1*03:01 and Bullous Pemphigoid in Iranian Patients

Background: A common Human Leukocyte Antigen (HLA) class II allele, DQβ1*03:01, seems to be associated with Bullous pemphigoid (BP) in Caucasians whereas previous studies in other ethnic groups showed other HLA class II alleles as genetic predisposing factors for BP. Objective: To investigate the association of HLA class II alleles and haplotypes with BP in Iranian population. Methods: Fifty pa...

[ 8 ] - بررسی فراوانی آلل‌های HLA-DRB1, DQB در بیماران مبتلا به سل قومیت سیستانی در مقایسه با افراد کنترل سالم

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...
