Background: Based on the reports, high frequency of special alleles of HLA class II genes might be associated with susceptibility to or protective from a particular cancer. These alleles might vary depending on the geographical region. Here we investigate the association between alleles of HLA class II genes and breast cancer in Iranian women.Methods: 100 patients with pathologically proved bre...
Background: HLA-G is a non-classical human leukocyte antigen expressed primarily in fetal tissues at the maternal-fetal interface. The unique structure of HLA-G molecule permits a restricted peptide presentation and allows the modulation of the immune system. There is now general agreement that HLA-G is an important immunotolerant molecule with the capability of inhibiting immune cell functions...
Abstract Background The clinical findings of Behçet’s disease (BD) differ according to the country and race investigated. most important genetic factor known in pathogenesis BD is HLA-B51, this positivity high countries on “Silk Road” where as frequent it Turkey. Although HLA B51 proven be Turkey, there are no studies area western Black sea demonstrating its relation demographic. We aimed inves...
common variable immunodeficiency (cvid) is a heterogeneous heritable disease characterized by arrest in b cell differentiation. an association between cvid and two hla haplotypes, haplotype i (hla-a1, hla-b8, hla-dr3) and haplotype ii (hla-a29, hla-b44, hladr7)has been previously documented. in the present study, we have attempted to find an association between susceptibility to cvid and hla cl...
study of kir expression and hla ligands in cd56+ lymphocytes of drug resistant tuberculosis patients
analysis of receptor–ligand interactions in the context of diseases necessitates to understand how hla–kir genotypes function in diseases. although cd56+ lymphocytes are derived from multiple lineages, they share a functional association with immunosurviellance and antimicrobial responses. the present study aimed to determine whether kir phenotype in cd56 lymphocytes and corresponding...
human leukocyte antigen-g which is an immune tolerance effecter molecule has an important role in the maintenance of fetus during pregnancy. abortion is one of the complications of pregnancy period. in this research, we have studied levels of hla-g 5, hla-g7 isoforms in the abortion-threatened pregnant women in comparison with controls. in a case-control study, 101 abortion-threatened women an...
سابقه و هدف: علی رغم پیشرفت زیاد در تولید انواع آنتی بیوتیک ها، هنوز عفونت عامل اصلی مرگ و میر در سوختگی ها است. این موضوع ناشی از تخریب پوست به عنوان اولین سد دفاعی بدن در ضایعه سوختگی و تغییراتی است که در سیستم ایمنی بیمار سوخته ایجاد می شود. هدف این مطالعه بررسی اثر سوختگی بر سیستم ایمنی سلولی است. مواد و روش ها: دو گروه افراد مورد بررسی قرار گرفتند: گروه بیمار شامل 18 نفر بود که 20 تا 60 در...
Background: Natural Killer (NK) cells, through mechanisms such as cytotoxicity and cytokine production, are among the first line of defence against infections. The ability of NK cytotoxicity is related to Killer cell immunoglobulin-like receptors (KIR) found on the cell surface. Interaction between KIRs and human leukocyte antigen (HLA) class I molecules regulate NK cells responses to eliminate...
studies on hla-g, a nonpolymorphic antigen of non-classical hla class i, is of basic and clinical significance. in the present study, the expression of hla-g proteins in the human skin tissue sections of normal and autoimmune pemphigus vulgaris (pv) individuals were investigated using monoclonal antibodies. the antibodies recognized both membrane-bound and soluble isoforms of hla-g. rt-pcr was ...
serology and dna techniques are employed for human leukocyte antigen (hla) typing in different transplant centers. results may not always correlate well and may need retyping with different technique. all the patients (with aplastic anemia, thalassemia, and immunodeficiency) and their donors, requiring hla typing for bone marrow transplant were enrolled in the study. serological hla typing was ...
