Human leukocyte antigen (HLA) class II molecule is an integral component of the immune response on which the majority of host genetic studies have concentrated. Many different HLA-II alleles have been demonstrated to play roles in HBV infection. PCR-SSOP methods were applied to determine the HLA-DRB1 genotypes of 769 unrelated healthy individuals from Han Chinese of Northeast China. The frequen...

The aim of this study was to investigate the influence of killer cell immunoglobulin-like receptor (KIR) genes and their human leucocyte antigen (HLA) ligands in the susceptibility of chronic Chagas disease. This case-control study enrolled 131 serologically-diagnosed Chagas disease patients (59 men and 72 women, mean age of 60.4 ± 9.8 years) treated at the University Hospital of Londrina and t...

UNLABELLED The HLA-DRB1 alleles encoding an amino acid sequence (QKRAA/QRRAA/RRRAA) at position 70 74 of the third hypervariable region of the β1 chain of the HLA-DRB1 gene, called shared epitope (SE), are associated with increased susceptibility to and severity of rheumatoid arthritis (RA) in different populations. OBJECTIVE To determine the frequency of HLA-DRB1 alleles in Brazilian patient...

The involvement of the human leukocyte antigen (HLA) in liver graft acceptance is controversial, but the frequency of acute rejection (AR) remains high in spite of the use of the modern immunosuppressive agents. The present study was aimed at determining whether an association exists between liver recipient HLA-C polymorphism and AR development that could influence graft acceptance. Four hundre...

The work was done to study immunogenetic peculiarities of neuroinflammatory diseases among Korean children. A total of 13 children with neuroinflammatory diseases (8 males and 5 females; mean age 4.6 +/-2.6 yr) were consecutively recruited. Geno-mic typing was performed on their HLA DRB/HLA DQB genes using PCR-SSOP/SSP techniques with gel immunoelectrophoresis. The frequencies of HLA-DR1 *15 in...

The objective of this study was to investigate the influence of the genes encoding the KIR receptors and their HLA ligands in the susceptibility of ocular toxoplasmosis. A total of 297 patients serologically-diagnosed with toxoplasmosis were selected and stratified according to the presence (n = 148) or absence (n = 149) of ocular scars/lesions due to toxoplasmosis. The group of patients with s...

For the 31st KIR Exchange, 4 DNA samples (KDNA#121-124) were shipped to participating laboratories on May 8, 2013. A total of 68 laboratories submitted their KIR typing results. The majority of the laboratories used either commercial or in-house developed sequence-specific primer (SSP) based PCR and sequence-specific oligonucleotide probe (SSOP) typing systems. The results for the 31st KIR Exch...

OBJECTIVES This study was undertaken to investigate the possible association of Fas gene mutation(s) or polymorphism(s) with systemic lupus erythematosus (SLE) in Japanese. METHODS Screening for structural defects of the Fas gene was performed by using reverse transcriptase-polymerase chain reaction (RT-PCR)/single-strand conformation polymorphism (SSCP) analysis in 57 patients with SLE, foll...

UNLABELLED Biomarkers provide certain values for diagnosis, monitor treatment efficacy, or for the development of novel therapeutic approach for particular diseases. Thus, the identification of specific of biomarkers for specific medical problems, including malignant diseases may be valuable in medical practice. In the study, we have used the Wilms' tumor gene (WT1) as a biomarker to evaluate i...

This Study aims to determine the effect of application Good Manucturing Practices (GMP) and preparation Sanitation Standard Operational Procedure (SSOP) on processing frozen squid, Hazard Analysis Critical Control Point (HACCP) system as a moderating variable. The results research that love been carried out show influence implementation Manufacturing (GMP), Sanitasi squid. However, is not able ...
