The Hodgkin's lymphoma disease (HD) is a common malignant neoplasm with germinal centre B-cell origin. It has been suggested that the HLA class I and class II regions have susceptibility effects on HD. In different ethnic groups, different HLA class I and class II alleles affect HD. As a result, there is no consensus which of the different HLA alleles confers susceptibility to HD. In this study...

Purpose HLA class I-specific killer cell immunoglobulin-like receptors (KIR) gene and HLA gene combinations have been associated with autoimmune uveitis (e.g., birdshot chorioretinopathy (BCR) and Vogt-Koyanagi-Harada syndrome (VKH)). In oligoarticular juvenile idiopathic arthritis (JIA), uveitis is one of the most serious complications, affecting approximately 20% of patients. Multiple studies...

HLA gene system is one of the most polymorphic regions of the human genome. The association of HLA class II genes in T1DM pathogenesis has been reported for several ethnicities. Associations of HLA class II genes with T2DM have revealed inconsistent results. Moreover, correlations between DN and HLA alleles remain unclear. We carried out DNA typing chip by specific medium resolution typing prob...

Loss of expression of HLA class I antigens has been demonstrated in a wide variety of tumors and is considered to be one of the mechanisms whereby tumors escape T-cell surveillance. Genomic DNA of MHC class I/II molecules in seven lung cancer cell lines was investigated and compared with that in peripheral blood mononuclear cells. In three cell lines, OU-LC-A1, OU-LC-A2, and OU-LC-AS1, a loss o...

Abstract Human natural killer (NK) cells are essential for controlling infection, cancer, and fetal development. NK cell functions modulated by interactions between polymorphic inhibitory immunoglobulin-like receptors (KIR) HLA-A, -B, -C ligands expressed on tissue cells. All HLA-C alleles encode a KIR ligand contribute to reproduction immunity. In contrast, only some HLA-A -B they focus By hig...

Major histocompatibility complex (MHC) molecules expressed on the surface of human immunodeficiency virus (HIV) are potential targets for neutralizing antibodies. Since MHC molecules are polymorphic, nonself MHC can also be immunogenic. We have used combinations of novel recombinant HLA class I and II and HIV/simian immunodeficiency virus (SIV) antigens, all linked to dextran, to investigate wh...

in this paper, the antigen and gene frequencies of class i hla antigens were evaluated in 1000 individuals in khorasan province in northeast iran, and compared with statistics of other countries. the results and a general discussion are presented.

Staphylococcal enterotoxins (SEs) have been shown to bind to major histocompatibility complex (MHC) class II proteins and stimulate T cells in a V beta-specific manner, and these V beta specificities for various SEs have been well documented in mice and humans. This study was undertaken in order to examine the ability of human class II molecules to present SEs to human and murine T cell hybrido...

We have sequenced the Pan troglodytes class I (Patr) molecules from three common chimpanzees and expressed them as single molecules in a class I-deficient cell line. These lines were utilized to obtain purified class I molecules to define the peptide binding motifs associated with five different Patr molecules. Based on these experiments, as well as analysis of the predicted structure of the B ...
