The non-donor-specific anti-HLA-Ia antibodies correlate significantly with lower graft survival in organ transplant patients. Based on our earlier findings that anti-HLA-E murine monoclonal antibodies (MEM-E/02 and 3D12) reacted with different HLA-Ia alleles and the peptides shared by HLA-E and HLA class, Ia alleles inhibited the HLA-Ia reactivity of the anti-HLA-E antibodies in normal non-allo...

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 ...

Multiple sclerosis (MS) is a complex trait in which alleles at or near the class II loci HLA-DRB1 and HLA-DQB1 contribute significantly to genetic risk. HLA-DRB1*15 and HLA-DRB1*17-bearing haplotypes and interactions at the HLA-DRB1 locus increase risk of MS but it has taken large samples to identify resistance HLA-DRB1 alleles. In this investigation of 7,093 individuals from 1,432 MS families,...

Chronic kidney disease is becoming a global public health problem, which will usually cause uremia at the end stage of chronic kidney failure. So far, kidney transplant is the most effective and proper therapy for uremia, however, the short supply of matched donor kidney has been a persistent bottleneck for transplantation. HLA matching of HLA-A, -B and -DRB1 loci is very important for the allo...

The aim of the present study was to analyze the distribution of HLA-A, -B, -Cw, and -DRB1 alleles among patients with psoriatic arthritis (PsA) in Croatia. DNA was isolated from peripheral blood of 58 PsA patients (28 male and 30 female) and tested by PCR-SSP (Polymerase Chain Reaction - Sequence Specific Primers) method for polymorphism of the above mentioned HLA loci. The strongest associatio...

The objective of this descriptive study was to determine Felis domesticus (cat) and Canis familiaris (dog) protein epitopes that bind strongly to selected HLA class II alleles to identify synthetic vaccine candidate epitopes and to identify individuals/populations who are likely to respond to vaccines. FASTA amino acid sequences of experimentally validated allergenic proteins of house cat and d...

introduction several lines of evidence support the contribution of autoimmune mechanisms in the pathogenesis of meniere’s disease. the aim of this study was determining the association between hla-cw alleles in patients with definite meniere’s disease and patients with probable meniere’s disease and a control group.  materials and methods: hla-cw genotyping was performed in 23 patients with def...

background: non-hodgkin lymphoma (nhl) includes a wide range of diseases with different clinical and biological features. nhl is usually presented as localized or generalized lymphadenopathy. it has been suggested that the hla class i and ii are associated with susceptibility to nhl. different ethnic groups have been found to have different hla class i and ii alleles which affect nhl. objective...

Chronic lymphocytic leukemia (CLL) is a malignant disorder of B cell origin, with low incidence in Asian populations. In this study we investigated the HLA-class I A and B allele frequencies in 87 Iranian CLL patients and 64 healthy controls using sequence specific primer-polymerase chain reaction (SSP-PCR) technique. Our results showed increased frequencies of HLA-A11:01 (p=0.02) and HLA-B35:0...

Prior studies using polyclonal populations of natural killer (NK) cells have revealed that expression of certain major histocompatibility complex (MHC) class I molecules on the membrane of normal and transformed hematopoietic target cells can prevent NK cell-mediated cytotoxicity. However, the extent of clonal heterogeneity within the NK cell population and the effect of self versus non-self MH...
