Human leukocyte antigens class II play an important role in immune response against HCV. We investigated whether HLA class II alleles influence susceptibility to HCV infection and response to interferon therapy. HLA-DRB1 and -DQB1 loci were genotyped using PCR-SSO Luminex technology. According to our regimen, 41 (66%) of patients achieved sustained virological response to combined treatment of ...

BACKGROUND The relationship between HLA-DRB1 alleles and asthma is controversial. The purpose of this study was to evaluate the relationship between HLA-DRB1 alleles and risk of asthma. MATERIAL AND METHODS We searched PubMed, Chinese National Knowledge Infrastructure (CNKI), Wan Fang (Chinese) database, and Chinese Biomedical Medical databases (CBM) to find studies on the relationship between ...

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...

To clarify the association between HLA-DRB1 alleles and chronic myelogenous leukemia (CML), the HLA-DRB1 allele frequencies in 50 Japanese patients each with b2a2 and b3a2 CML and 127 healthy Japanese individuals were examined. In the patients with b2a2 CML, the frequencies of HLA-DRB1*0405, DRB1*08032, and DRB1*1502 were low and that of HLA-DRB1*1201 was high in comparison with the healthy ind...

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...

BACKGROUND Little is known about the associations between human leukocyte antigens (HLAs) and food allergies. Our aim was to analyze the associations between the HLA class II polymorphism and food allergy using bioinformatics. METHODS A two-step algorithm was developed which mimics the food allergen processing in the human body. In the first step, the allergen is digested by pepsin, trypsin a...

Mechanisms for observed associations within the major histocompatibility complex (MHC) and autoimmune diseases including multiple sclerosis (MS) remain uncertain. Genotyping of the HLA Class II DRB1 locus in 4347 individuals from 873 multiplex families with MS highlights the genetic complexity of this locus. Excess allele sharing in sibling pair families lacking DRB1*15 and DRB1*17 (58.5% shari...

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...

26 Background. The frequency of autoantibodies against glutamic acid decarboxylase-65 27 (GAD65), and ICA512/IA2 (IA2) are a function of the specific human leukocyte antigen 28 (HLA) in type 1 diabetes mellitus (T1D). We investigated the association of HLA class II 29 (DR, DQ) alleles and haplotypes with the presence of GAD and IA-2 autoantibodies in T1D. 30 Methods. Autoantibodies were tested ...
