Abstract HLA class I molecules that represent ligands for the inhibitory killer cell Ig-like receptor (KIR) 3DL1 found on NK cells are categorically defined as those HLA-A and HLA-B allotypes containing Bw4 motif, yet KIR3DL1 demonstrates hierarchical recognition of these HLA-Bw4 ligands. To better understand molecular basis underpinning differential recognition, HLA-ABw4 family were investigat...

Background: Human leukocyte antigen (HLA)-G is a nonclassical HLA class I molecule with modulatory effects on NK and T cells. Because HLA-G expression is frequently detected in different solid tumors, it may be involved in tumor immune evasion. Objective: This study was designed to elucidate the prognostic value of HLA-G in hepatocellular carcinoma (HCC) and pancreatic adenocarcinoma (PADC). Th...

CELL lines are widely used in laboratories for in vitro experiments, especially for investigating abnormal hallmarks in cancer cells and identifying therapeutic targets. Human cell lines are typically derived in academic laboratories from a wide range of cancer samples. To achieve a representation of intracancer heterogeneity, several laboratories, including ours, have established cell line col...

Objective(s): The population in Iran is a genetic admixture of the ancestral Aryan and other populations neighboring Iran. Different ethnic groups in Iran show wide regional distributions for many human leukocyte antigen (HLA) alleles. Therefore, it is necessary and sensible to study the differences in HLA allele distribution in different area. We studied the HLA class I and II allele frequenci...

Aim.To study the immunogenetic prerequisites of idiopathic recurrent spontaneous pregnancy losses in humans allo- and autoimmune genesis. Methods. PCR-SSP (polymerase chain reaction with sequence-specific primers). Results. A comprehensive analysis distribution frequency allelic variants HLA-DRB1, HLA-DQA1, HLA-DQB1 genes testifies to an increased risk a total homology 50 % or more couples pres...

 Background and purpose: Major histocompatibility antigens are the most polymorphic components of the immune system. The purpose of this study was to determine the frequency of human leukocyte antigens (HLA) in a population in Mazandaran province, Iran. Materials and methods: In a cross sectional study, peripheral blood samples were obtained from 550 people in Immunogenetics Research Center af...

We propose an approach to automated 3D reconstruction of plant architecture followed by a precise derivation of phenotypic traits. We applied and evaluated our approach within a grapevine phenotyping project. The reconstruction results and the derived phenotypic traits could be shown to be in line with given ground truth data. Furthermore, our approach that combines a generative modelling of pl...

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...

Background: Graves’ disease (GD), a highly rampant autoimmune disorder of the thyroid gland, is responsible for 60-80% of the clinical cases of hyperthyroidism. Over the past decades, genetic association studies have identified several GD susceptibility loci in CTLA-4, TSHR and major histocompatibility complex regions. The information on the association between the human leukocyte antigens (HLA...

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)...
