Objective: This study aimed to investigate the association between HLA alleles and visceral leishmaniasis (VL) in a sample of Iraqi patients. Methods: A total of 30 patients were studied, in addition to 20 age, gender and ethnicity matched controls. All subjects were genotyped by polymerase chain reaction-sequence specific primers (PCR-SSP) method. Results: For HLA-class I region (A and B loci)...

Background: The HLA class I molecules serve as ligands for both T cell receptors and killer cell immunoglobulin-like receptors (KIRs). Objective: We investigated the HLAC and HLA-Bw4 alleles as well as KIRs expression on CD56 positive lymphocytes to evaluate whether these genes and molecules could influence Ankylosing spondylitis (AS) susceptibility, alone or in combination. Methods: We typed 4...

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...

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: 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...

Background: Pulmonary tuberculosis (PT) is one of the endemic diseases in Iraq, and among the suggested predisposing factors are alleles of the human leukocyte antigen (HLA) system. We sought to investigate the association between HLA-class I (A and B) and -class II (DR and DQ) alleles in a sample of PT Iraqi patients.Methods: lymphocytes of 105 PT patients and 40 controls were phenotyped for H...

Background: It has been arguedthat unprecedented degree of human leukocyte antigen (HLA) loci polymorphism within a population is requiredto avoid the devastating effects of infectious diseases. The present study was conducted to determine the associations between some of HLA classI genes and the outcome of hepatitis B virus (HBV) infection. Methods: Using sequential sampling method, 64 individ...

background: interaction between killer cell immunoglobulin-like receptors (kir) and human leukocyte antigen (hla) class i molecules is important for regulation of natural killer (nk) cell function. objective: the aim of this study was to investigate the impact of compound kir-hla genotype on susceptibility to acute leukemia. methods: cohorts of iranian patients with acute myeloid leukemia (aml;...
