Abstract Mumps is nowadays re-emerging despite vaccination. The contribution of T cell immunity to protection against mumps has not been clearly defined. Previously, we described a set 41 peptides that were eluted from human leukocyte antigen (HLA) class I molecules virus (MuV)-infected cells. Here, confirmed immunogenicity five novel HLA-B*07:02- and HLA-A*01:01-restricted MuV epitopes this pe...

Background and Aims: The human leukocyte antigen-E (HLA-E) is a member of non-classical HLA class-I genes which is highly conserved through evolution. In general, so far 25 alleles of HLA-E have been described. However, the existence of only two allelic group; HLA-E*01:01 and HLA-E*01:03 have been demonstrated in all the populations. HLA-E*01:01 and HLA-E*01:03 differ only at codon 107 of exon ...

Kidney Exchange Programs (KEP) are valuable tools to increase the options of living donor kidney transplantation for patients with end-stage disease an immunologically incompatible live donor. Maximising benefits a KEP requires information system manage data and optimise transplants. The input specifications systems that relate key on blood group Human Leukocyte Antigen (HLA) types HLA antibodi...

Background: Natural killer (NK) cells are the effector cells of innate immunity that respond to infection and tumor. Interactions between killer cell immunoglobulin like receptors (KIR) and human leukocyte antigen (HLA) class I molecules regulate NK cells responses to eliminate infected and transformed cells. Objective: To investigate the impact of KIR genes, HLA ligand genes, and KIR-HLA combi...

Whether autoimmune mechanisms play a role in the pathogenesis of inclusion body myositis (IBM) is unknown. Human leukocyte antigen (HLA) analysis in 52 patients, including 17 with autoimmune disorders (AIDs), showed that patients were more likely to have antigens from the autoimmune-prone HLA-B8-DR3 ancestral haplotype than healthy control subjects, irrespective of the presence of AIDs. Patient...

successful clearance of hepatitis b virus (hbv) is a promising event in which host's immune system will attempt to get rid of the virus. the immunological events of hbsag seroclearance have attracted great attention in both natural history investigations and therapeutic trials. recent genome-wide association studies (gwas) has confirmed polymorphisms in the human leukocyte antigen (hla)-dp locu...

The transporter associated with antigen processing (TAP) translocates the cytosol-derived proteolytic peptides to the endoplasmic reticulum lumen where they complex with nascent human leukocyte antigen (HLA) class I molecules. Non-functional TAP complexes and viral or tumoral blocking of these transporters leads to reduced HLA class I surface expression and a drastic change in the available pep...

Background & Objective: Unexplained recurrent spontaneous abortion (URSA) is defined as an unknown cause of occurrence of three or more clinically detectable pregnancy losses before 20 weeks of gestation, but it occurs presumably as a result of the immune system dysfunctions. We supposed that the disruption of semen or spermatozoa might be responsible for the dysfunction of the...

recurrent aphthous stomatitis (ras) is known as the most common chronic disease of the oral cavity, which affects a range of 5-25% of the population. ras appears to be associated with some human leukocyte antigen (hla) class ii alleles and haplotypes. this study attempts to survey the distribution of hla-drb and -dqb alleles among iranian ras patients and healthy controls. in order to evaluate ...

host genetic factors play a central role in determining the clinical phenotype of human diseases. association between two polymorphic loci in human genome, human leukocyte antigen (hla) and killer cell immunoglobulin-like receptors (kirs), and genetically complex infectious disease, particularly those of viral etiology, have been historically elusive. hence, defining the influence of genetic di...
