Multiple Sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. It is a clinically heterogeneous disorder especially in terms of disease severity. Current investigations suggest that genes and gene-gene interactions not only influence on susceptibility to MS but also affect the disease severity. In this study, we investigated the contribution of the HLADRB1*1501 ...

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...

OBJECTIVE Human leukocyte antigen (HLA) DRB1*04:36 is a low-frequency HLA-DRB1 allele. The aim here is to report the ethnicity of DRB1*04:36 and its associated HLA haplotypes among Taiwanese individuals. MATERIALS AND METHODS A sequence-based typing method was employed to confirm this low incidence allele. Polymerase chain reaction was performed to amplify exons 2 and 3 of the HLA-A and HLA-B...

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...

OBJECTIVE Type 1 diabetes mellitus (T1D) is an autoimmune and multifactorial disorder. Subsequent analysis on human leukocyte antigen ( HLA) region shows that HLA-DRB1 and -DQB1 genes have the strongest association with T1D. In this study, for the first time, we investigated the influence of gender on the HLA-DRB1 and -DQB1 association with type 1 diabetes mellitus in Iranian patients in order ...

OBJECTIVE The aim of this study was to determine the frequency of HLA DR-DQ haplotypes in children with type 1 diabetes mellitus (T1DM) in the Southeast Region of Turkey. METHODS Eighty children and adolescents with T1DM and eighty control subjects participated in the study. HLA-DR, DQ was typed using polymerase chain reaction and sequence-specific priming technique. RESULTS HLA DRB1*03 all...

Of identified genetic variants, HLA polymorphisms confer the greatest risk for developing autoimmune diseases, including rheumatoid arthritis (HLA-DRB1*04). There are strong influences of HLA polymorphisms on cell type-specific gene expression in B cells and monocytes. Their influence on gene expression in CD4(+) T cells is not known. We determined transcript and proteins levels of target genes...

PURPOSE Vogt-Koyanagi-Harada disease (VKH), an autoimmune disease targeted against melanocytes, is associated with HLA-DRB1*0405. This study was undertaken to analyze T-cell recognition and the cytokine expression profile induced by melanocyte epitopes in HLA-DRB1*0405-positive and -negative patients with VKH uveitis. METHODS Peripheral blood mononuclear cells (PBMC) proliferation and Th1 (IF...

OBJECTIVE We report here the human leukocyte antigen (HLA) allelic variety and haplotype composition in a cohort of the Taiwanese Chinese population and their patterns of linkage disequilibria on HLA-B: HLA-C alleles and HLA-DRB1: HLA-DQB1 alleles at a high-resolution level. MATERIALS AND METHODS Peripheral whole blood from 11,423 Taiwanese Chinese unrelated individuals was collected in acid ...
