Objective(s): HTLVI-1 is the first human retrovirus with limited endemic regions in the world. The epidemiological studies have shown that the genetic background and immune response to the virus have a significant role in HTLV-I-associated diseases. Among the genes are involved in HTLV-I infection, the role of human leukocytes antigen (HLA) have been studied in different population. In the pre...
AIMS To study the expression of HLA-DR antigen in the different histological types of gastric polyps. METHODS Ninety five cases of gastric polyps were histologically classified and examined for the presence of Helicobacter pylori, and for degree and type of inflammation. Further sections were stained immunohistochemically for HLA-DR antigen expression in the epithelium using a monoclonal anti...
Abstract We investigated the genetic profiles of killer cell immunoglobulin-like receptors (KIRs) in Ebola virus–infected patients. studied relationship between KIR–human leukocyte antigen (HLA) combinations and clinical outcomes patients with virus disease (EVD). genotyped KIRs HLA class I alleles using DNA from uninfected controls, EVD survivors, persons who died EVD. The activating 2DS4–003 ...
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 ...
OBJECTIVE Associations between human leukocyte antigens (HLA) and sarcoidosis have been reported in several studies. We aimed to investigate these associations in Turkish patients. PATIENTS AND METHOD We performed HLA-A, HLA-B, HLA-C, and HLA-D typing in 83 patients with sarcoidosis and in 250 healthy controls using a microlymphocytotoxicity method to investigate genetic susceptibility to the...
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.
background occult hepatitis b infected (obi) patients cannot eradicate hepatitis b virus (hbv)-dna from their liver and peripheral blood, completely. objectives the main aim of this study was to investigate the rate of hla-a2 expression on peripheral blood mononuclear cells (pbmcs) of patients with obi. materials and methods in this experimental study, intensity of hla-a2 was measured on the pb...
Forty consecutive patients with uveitis constituted the probands. Behqet's disease was excluded by O'Duffy's criteria.2 The diagnosis and the localisation of the uveitis was based on clinical symptoms and signs. The nonspecific hypersensitivity to the needleprick pathergy test was done as previously described.3 The tissue typing for HLA B5 and HLA B27 was done with antisera against these 2 spec...
introduction: human leukocyte antigen (hla) genes are the most polymorphic loci in the human genome. they predict the outcome of transplantation by detecting self from non-self antigens. the best use of hla typing is to find a hla-match donor for bmt candidate patients. evidence suggests that matching unrelated donors and recipients for hla-a, -b and -drb1 loci is a prediction for an improved o...
Background: During pregnancy, the maternal immune system is in close contact with cells and tissue from the semiallogenic fetus .The Human Leucocyte Antigen (HLA) class Ib molecules, HLA-E, -F and -G, are expressed at the materno-fetal interface. Because of the apparent immunoregulatory functions of these proteins, they may be involved in successful acceptance of the semi-allogenic fetus during...
