Background Host genetic factors are the major determining factor for variation in response to HIV infection and are related to resistance among HIV patients. HLA dRB1*1501, DRB1*1502, DRB1*1301, DRB1*1302, DRB1*1101-05 are widely reported alleles associated with low viraemia in infected individuals. Computational predictions have made it possible to identify potentially strong peptide binders t...

Multiple sclerosis (MS) is a common inflammatory disease of the central nervous system unsurpassed for variability in disease outcome. A cohort of sporadic MS cases (n = 163), taken from opposite extremes of the distribution of long-term outcome, was used to determine the role of the HLA-DRB1 locus on MS disease severity. Genotyping sets of benign and malignant MS patients showed that HLA-DRB1*...

OBJECTIVE To use a panel of monoclonal antibodies (Mab) which recognise HLA class II alleles associated with rheumatoid arthritis for fluorescence activated cell sorter (FACS) analysis of peripheral blood mononuclear cells (PBMNC) from patients with early and established rheumatoid arthritis and to compare these results against DNA oligotyping of HLA class II molecules in the same patients. M...

OBJECTIVE To determine whether extraarticular manifestations (EAM) in rheumatoid arthritis (RA) patients from northwest (NW) Spain are associated with particular HLA-DRB1 alleles and/or TNF microsatellite polymorphisms. METHODS The frequencies of HLA-DRB1 alleles and TNF microsatellite polymorphisms were compared between RA patients with and without extraarticular disease in a population from...

BACKGROUND AND AIMS This study was comprised of Iranian children with oligoarthritis and rheumatoid factor negative (RF) polyarthritis subtypes of juvenile idiopathic arthritis (JIA) to determine the association of HLA-DRB1 alleles in Iran. METHODS HLA-DRB1 alleles were investigated in 33 Iranian children with oligoarthritis and RF negative polyarthritis JIA and compared with 45 healthy contr...

To investigate why human leukocyte-associated antigen-DRB1*0301 (HLA-DRB1*0301) positive Scandinavian patients have a better prognosis than HLA-DRB1*0301 negative patients, the present authors examined patterns of cytokine expression in bronchoalveolar lavage (BAL) cells and BAL fluid (BALF) from patients with pulmonary sarcoidosis and controls. Using real-time PCR, the mRNA expression of selec...

Idiosyncratic lapatinib-induced liver injury has been reported to be associated with human leukocyte antigen (HLA)-DRB1*07:01. In order to investigate its mechanism, interaction of lapatinib with HLA-DRB1*07:01 and its ligand peptide derived from tetanus toxoid, has been evaluated in vitro. Here we show that lapatinib enhances binding of the ligand peptide to HLA-DRB1*07:01. Furthermore in sili...

Bacterial adherence to the acquired dental pellicle, important in dental caries (caries), is mediated by receptor-adhesins such as salivary agglutinin binding to Streptococcus mutans antigen I/II (I/II). Ten selected I/II epitopes were chosen to determine their reactivity to human salivary IgA. Previous studies suggested that a specific HLA biomarker group (HLA-DRB1*04) may have differential in...

PURPOSE Juvenile idiopathic arthritis (JIA)-associated uveitis can lead to ocular complications and vision loss. Alleles HLA-DRB1*08, *11, and *13 are risk alleles for JIA, whereas HLA-DRB1*11 and *13 alleles increase uveitis susceptibility. We examined the association of common HLA-DRB1 alleles in children with JIA alone and JIA-associated uveitis. METHODS High-resolution HLA-DRB1 genotyping...

BACKGROUND Data on allele frequencies (AFs) and haplotype frequencies (HFs) of HLA-C and -DQB1 are limited in Koreans. We investigated AFs and HFs of HLA-A, -B, -C, -DRB1, and -DQB1 in Koreans by high-resolution sequence-based typing (SBT). METHODS Hematopoietic stem cells were obtained from 613 healthy, unrelated donors to analyze HLA-A, -B, -C, -DRB1, and -DQB1 genotypes by using AlleleSEQR...
