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...
To investigate the human leukocyte antigen (HLA) association with anti-synthetase syndrome (ASSD). We conducted largest immunogenetic HLA-DRB1 and HLA-B study to date in a homogeneous cohort of 168 Caucasian patients ASSD 486 ethnically matched healthy controls by sequencing-based-typing. A statistically significant increase HLA-DRB1*03:01 HLA-B*08:01 alleles compared was disclosed (26.2% versu...
the association of hla class ii genes with ulcerative colitis (uc) as an autoimmune disease has been investigated for several years. however, factors responsible for genetic predisposition of this disease have so far not been clearly understood. in this study, for the first time, we aimed to investigate the association between hla-drb1 types and uc in the population of kerman, a city southeast ...
background: the human leukocyte antigen-drb1 (hla-drb1) locus is one of the most polymorphic human loci and has a crucial role in the immune system. assessing the allelic frequencies of hla-drb1 locus would be a fundamental factor in defining the origin of populations, relationships with other populations, disease association studies and the constitution of unrelated bone marrow donor registrie...
Autoimmune diseases (AIDs) are characterized by a multifactorial aetiology and a complex genetic background, with the MHC region playing a major role. We genotyped for HLA-DRB1 locus 1228 patients with AIDs-213 with Systemic Lupus Erythematosus (SLE), 166 with Psoriasis or Psoriatic Arthritis (Ps + PsA), 153 with Rheumatoid Arthritis (RA), 67 with Systemic Sclerosis (SSc), 536 with Multiple Scl...
BACKGROUND The human leukocyte antigens (HLAs) are proteins found in the membranes of nearly all nucleated cells. People with certain HLA antigens are more likely to develop certain autoimmune diseases. The aim of this study was to determine the frequency of HLA-DRB1 in children with autoimmune hepatitis (AIH) as a risk factor for occurrence, its relation to preceding hepatitis A infection and ...
OBJECTIVE To provide a table indicating the risk for developing anti citrullinated protein antibody (ACPA) positive rheumatoid arthritis (RA) according to one's HLA-DRB1 genotype. METHODS We HLA-DRB1 genotyped 857 patients with ACPA positive RA and 2178 controls from South Eastern and Eastern France and calculated Odds Ratios (OR) for developing RA for 106 of 132 possible genotypes accounting...
Background: Human leukocyte antigens (HLA) are polymorphic cell surface proteins. Distribution of HLA alleles vary among different racial and ethnic populations in unrelated stem cell registries. Determination of HLA allele frequencies in different ethnic groups is useful for population genetic analyses. Materials and Methods: Based on data available from the Iranian Stem Cell Donor Registry...
BACKGROUND Previous studies on the influence of HLA-DRB1 alleles on multiple sclerosis (MS) susceptibility and clinical course have mostly employed the 2-point genotyping method. OBJECTIVE To assess the influence of HLA-DRB1 alleles and allele interactions on disease risk and clinical course in a large West Australian MS patient cohort using high-resolution genotyping. METHODS Four digit HL...
چکید ه سابقه و هدف ژن های مجموعه اصلی سازگاری نسجی( mhc ) دارای بیشترین تنوع ژنتیکی در ژنوم هر گونه می باشند. ژن هـای mhc انسانـی بـر روی کـروموزوم 6 واقـع شـده و hla نامیده می شوند. آنتی ژن های کلاس i و ii hla ، کنترل ژنتیکی پاسخ های ایمنی را به عهده دارند. شناسایی آلل های hla به طور وسیعی در امر پیوند، بیماری های مرتبط با hla و مطالعات جمعیت شناسی مورد استفاده قرار می گیرند. در میان ژن ها...
