BACKGROUND The human immunodeficiency virus type 1(HIV-1) epidemic in Chongqing, China, is increasing rapidly with the dominant subtype of CRF07_BC over the past 3 years. Since human leukocyte antigen (HLA) polymorphisms have shown strong association with susceptibility/resistance to HIV-1 infection from individuals with different ethnic backgrounds, a recent investigation on frequencies of HLA...
HLA class II genes are strongly associated with susceptibility and resistance to insulin-dependent diabetes mellitus (IDDM). The present study reports the HLA-DRB1 genotyping of 41 IDDM patients and 99 healthy subjects from the Southeast of Brazil (Campinas region). Both groups consisted of an ethnic mixture of Caucasian, African Negro and Amerindian origin. HLA-DRB1*03 and *04 alleles were fou...
Background Lupus nephritis (LN) is one of the main clinical challenges in systemic lupus erythematosus (SLE) and a cause significant morbidity mortality. Genetic contribution to SLE pathogenesis important, genetic profiling through polygenic risk scores has been shown useful stratify patients according dominating molecular disease mechanism. [1] This not, however, investigated for specific mani...
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...
objective The protective effect of HLA-DRB1 alleles on the development of rheumatoid arthritis (RA) is poorly understood. We performed a meta-analysis of four European populations to investigate which HLA-DRB1 alleles are associated with protection in anticitrullinated protein antibody (ACPA)-positive and ACPA-negative RA. methods More than 2800 patients and 3000 controls with information on HL...
BACKGROUND Type 1 diabetes (T1D) is a multifactorial autoimmune disorder where interaction and integration of immune response genes along with environmental factors play a role in autoimmune destruction of the insulin producing Pancreatic Beta cells. METHODOLOGY/PRINCIPAL FINDINGS We have studied four single nucleotide polymorphisms (FokI site in Exon 2, BsmI and ApaI sites in Intron 8 and Ta...
Idiosyncratic ximelagatran-induced hepatotoxicity has been reported to be associated with human leukocyte antigen (HLA)-DRB1*07:01 and ximelagatran has been reported to inhibit the binding of the ligand peptide to HLA-DRB1*07:01 in vitro. In order to predict the possible interaction modes of ximelagatran with HLA-DR molecules, in silico docking simulations were performed. Molecular dynamics (MD...
OBJECTIVE The HLA 8.1 ancestral haplotype (HLA-B*08/DRB1*03/DQA1*05/DQB1*02) is associated with adult/juvenile idiopathic inflammatory myopathy (IIM), but confers a greater strength of association in patients possessing anti-Jo-1 or anti-PM-Scl antibodies. The HLA-DPB1 gene is centromeric to other HLA class II loci and separated by a recombination hotspot. We investigated whether HLA-DPB1 assoc...
Hepatitis C virus (HCV) infection is a global medical problem. The current standard of treatment consists of the combination of peginterferon plus ribavirin. This regimen eradicates HCV in 55% of cases. The immune response to HCV is an important determinant of disease evolution and can be influenced by various host factors. HLA class II may play an important role in immune response against HCV....
The relative importance of various human leukocyte antigen (HLA) loci and the resolution level at which they are matched has not been fully defined for unrelated donor transplantation. To address this question, National Marrow Donor Program data from 3857 transplantations performed from 1988 to 2003 in the United States were analyzed. Patient-donor pairs were fully typed for HLA-A, -B, -C, -DRB...
