Context: Hepatitis C Virus (HCV) infection is a major cause of chronic cirrhosis and hepatocellular carcinoma. Approximately 30% infected persons with HCV spontaneously clear the viral infection; but, some remaining patients develop HCV. Studies show that HLA molecules play an important role in outcome by influencing efficiency antiviral immune response to infection. It now known polymorphisms ...
OBJECTIVES HLA-DRB1*03 is strongly associated with anti-Jo-1-positive idiopathic inflammatory myopathies (IIM) and there is now increasing evidence that Jo-1 antigen is preferentially expressed in lung tissue. This study examined whether smoking was associated with the development of anti-Jo-1 antibodies in HLA-DRB1*03-positive IIM. METHODS IIM cases were selected with concurrent information ...
In Arabidopsis thaliana, efficient microRNA (miRNA) production requires DICER-LIKE1 (DCL1) with the assistance of a partnering protein, DOUBLE-STRANDED RNA BINDING1 (DRB1) or DRB2. The presence of either of these DRB proteins is crucial to determine the mode of action of a miRNA; i.e., cleavage or translation inhibition. Here we studied the structural determinants for the role of DRB1 and DRB2 ...
Variation in major histocompatibility complex genes on chromosome 6p21.3, specifically the human leukocyte antigen HLA-DR2 or DRB1*1501-DQB1*0602 extended haplotype, confers risk for multiple sclerosis (MS). Previous studies of DRB1 variation and both MS susceptibility and phenotypic expression have lacked statistical power to detect modest genotypic influences, and have demonstrated conflictin...
AIM To determine the association between HLA-DRB1 haplotypes and risk of cervical cancer in unselected and samples from Chinese ethnicities. METHODS A comprehensive search for articles from their inception to April 1st, 2013 was conducted from PubMed, Medline, Elsevier Science, Springer Link, Cochrane Library database, China biology medical literature database (CBM),China National Knowledge I...
HLA DRB1, DQA1 and DQB1 alleles were determined by DNA PCR-SSO typing in a sample of 99 individuals originating from Wielkopolska (midwestern Poland). A high number of alleles (38 DRB1, 8 DQA1 and 14 DQB1) was detected at each locus, many of them presenting notable frequencies in this population. The three HLA loci are thus characterized by very high heterozygosity levels (93% for DRB1, 85% for...
Of 957 patients with type 1 diabetes without known Addison's disease 1.6% (n = 15) were positive for 21-hydroxylase autoantibodies. Among DQ8/DQ2 heterozygous patients, the percentage expressing 21-hydroxylase autoantibodies was 5% (10 of 208) vs. less than 0.5% of patients with neither DQ8 nor DQ2. Three of the diabetic patients found to have 21-hydroxylase autoantibodies on screening were sub...
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 identification of a vitamin D-responsive (VDRE) motif within the HLA-DRB1*15:01 promoter region provides an attractive explanation for the combined effects of HLA-DR inheritance and vitamin D exposure on multiple sclerosis (MS) risk. We therefore sought to incorporate HLA-DRB1 promoter variation, including the VDRE motif, in an assessment of HLA-DRB1-associated MS risk. METHODS ...
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...
