The power of a genetic mapping study depends on the heritability of the trait, the number of individuals included in the analysis, and the genetic dissimilarity among them. In experiments that involve microarrays or other complex physiological assays, phenotyping can be expensive and time-consuming and may impose limits on the sample size. A random selection of individuals may not provide suffi...
مقدمه: تعداد 500 نفر از مردم اصفهان که از سلامتی کامل برخوردار بودند، از لحاظ آنتی ژنهای گروه یک hla شامل c و b و hla-a مورد آزمایش قرار گرفتند. روش: لنفوسیتها از 5 میلی لیتر خون وریدی جدا شد و با استفاده از روش استاندارد دو مرحله ای میکرولنفوسیتوتوکسیسیتی nih، از نظر آنتی ژنهای c و b و hla-a بررسی گردید. نتایج: شیوع آنتی ژنهای b35 و hla-b5 و hla-cw4 و a9 و a3 و a2 و hla-a1، در جمعیت مورد مطالع...
background: the study aimed to examine the association between human leukocyte antigen (hla) class ii allele frequencies and breast cancer in iranian women. methods: a total of 100 patients with pathologically proven breast cancer who referred to cancer institute were randomly selected and compared with a group of age matched healthy blood donors (n = 80). hla class ii alleles were determined b...
HLA (Human Leukocyte Antigen) gene is located on chromosome 6’s short arm, including several loci. genotyping necessary for transplantation, especially in hematopoietic stem cell transplantation. A cross-sectional study to determine the frequency of HLA-A, HLA-B, and HLA-DRB1 alleles 122 patients admitted National Children’s Hospital Hematopoietic transplantation from year between 2010 2020. Th...
Background: The outcome of acute hepatitis B infection may be influenced by host genetic factors like human leukocyte antigen (HLA). To investigate the association between the HLA-DRB, DQA1 and DQB1 alleles and chronic hepatitis B infection, 50 patients with chronic hepatitis B (based on 6 months positive of HBsAg and HBc antibody and HBeAg and antibody by serological test), were selected from ...
A potential factor influencing hematopoietic stem cells transplantation (HSCT) outcome is the presence of donor-derived alloreactive natural killer (NK) cells. This retrospective analysis studied the impact of NK alloreactivity based on the missing KIR ligand, for acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) patients undergoing non-T-cell depleted HLA-identical sibling HS...
Background: HLA-G, as a tolerogenic molecule, expressed in cytotrophoblast cells and playing an important role in the suppression of the immune response in maternal decidua. Today Interaction of the extracellular domains of HLA-G protein with cell receptors of immune system, including CD8, LILRB1, LILRB2 and killer cell immunoglobulin-like receptor KIR2DL4, was well known. Materials and Methods...
Introduction: The major histocompatibility complex (MHC) is a group of cell surface proteins that are essential for recognizing foreign molecules in human and other mammals. The physiologic function of MHC molecules is the presentation of peptides to T cells. In this study, we evaluated the purification of a class II MHC molecule (HLA-DR) from a human Burkitt′s lymphoma cell line; Daudi...
