Human leukocyte antigens (HLA) DRB1*03 and DRB1*02 have been associated with systemic lupus erythematosus (SLE) in Caucasians and black populations. It has been observed that certain HLA alleles show stronger associations with SLE autoantibodies and clinical subsets, although they have rarely been associated with lupus renal histologic class. In the present study, HLA-DRB1 allele correlations w...
BACKGROUND Knowledge of allele and haplotype frequencies of the human leukocyte antigen (HLA) system is important in the search for unrelated bone marrow donors. The Brazilian population is very heterogeneous and the HLA system is highly informative of populations because of the high level of polymorphisms. AIM The aim of this study was to characterize the immunogenetic profile of ethnic grou...
Clinical heterogeneity in multiple sclerosis is the rule. Evidence suggests that HLA-DRB1*15 may play a role in clinical outcome. Spinal cord pathology is common and contributes significantly to disability in the disease. The influence of HLA-DRB1*15 on multiple sclerosis spinal cord pathology is unknown. A post-mortem cohort of pathologically confirmed cases with multiple sclerosis (n = 108, 3...
Zinc transporter 8 autoantibodies (ZnT8A) were analyzed in sera from 1,504 subjects as part of the Type 1 Diabetes Genetics Consortium (T1DGC) Autoantibody Workshop. For these participants with type 1 diabetes (T1D), samples were collected within 3 years of T1D diagnosis. ZnT8A were detected in 862 subjects (57.3%), with the highest frequencies and median titers being associated with the shorte...
Objective : a retrospective analysis of the results obtained by typing HLA-A, -B antigens and HLA DRB1 allele groups in patients with rheumatoid arthritis (RA) Rostov population. Materials methods rheumatic inflammatory diseases who were on inpatient treatment rheumatology department SBI “OKB No. 2” was carried out LITT RO "BTS" 2019-2020. 41 (9 men, 32 women, median age — 42 years) diagnosed R...
Ten novel HLA-DRB1 and one DRB3 alleles are described. Eight of the variants are single-nucleotide substitutions, four resulting in an amino acid change (DRB1*1145, *1148, *0828 and *1514) and four with silent substitutions (DRB1*040504, *130103, *160502 and DRB3*020204). Two alleles differ by two nucleotide changes altering one (DRB1*1447 and *1361) amino acid and one allele alters three nucle...
The contribution of HLA DRB-DQB to type 1 diabetes (T1D) in Bahrainis, Lebanese, and Tunisians was investigated. DRB1*030101-DQB1*0201 was a locus that conferred susceptibility in three populations, while DRB1*040101-DQB1*0302 was a locus that conferred susceptibility only in Tunisians and Bahrainis. The DRB1*100101-DQB1*050101 (Bahrainis) and DRB1*150101-DQB1*060101 (Lebanese) loci were largel...
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...
Background: Human leukocyte antigen (HLA) complex is a gene family involved in antigen presentation associated with protection or susceptibility to inflammatory, infectious and autoimmune diseases. Atherosclerosis is a chronic inflammatory disease in which HLA molecules play a role in the initiation and development of the disease through presentation of self or foreign antigens to T cells. Obje...
OBJECTIVES To analyze association of different HLA genotypes for predisposition to type-I autoimmune hepatitis in Western India. METHODS This study was undertaken on patients of type-I autoimmune hepatitis (defined by international criteria by IAHG, 1999). HLA genotyping for class I and II was done in 20 patients of autoimmune hepatitis and 100 healthy controls. Statistics were done using Hal...
