Background and Aim: Major Histocompatibility Complex (MHC) is the most polymorphic system in the genome of different species. In human beings, it named human leukocyte antigen (HLA). The association between genetics, particularly the genes of the MHC and many Infection diseases especially viral infection has been known. The aim of this study is survey of association of HLA-B*51 and -B*52 allele...

OBJECTIVE To find an association between human leukocyte antigen (HLA) class II DRB1, DRB3, DRB4, and DRB5 alleles frequencies in a sample of Iraqi patients with Guillain-Barre syndrome (GBS) and compare with a healthy control group. METHODS We performed a cross-sectional study consisting of 30 Iraqi Arab patients with GBS attending the Neurological Department in the Neuroscience Hospital, Ba...

To investigate why human leukocyte-associated antigen-DRB1*0301 (HLA-DRB1*0301) positive Scandinavian patients have a better prognosis than HLA-DRB1*0301 negative patients, the present authors examined patterns of cytokine expression in bronchoalveolar lavage (BAL) cells and BAL fluid (BALF) from patients with pulmonary sarcoidosis and controls. Using real-time PCR, the mRNA expression of selec...

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...

Human leukocyte antigen-G (HLA-G) is a low polymorphic nonclassical HLA-I molecule restrictively expressed and with suppressive functions. HLA-G gene products are quite complex, with seven HLA-G isoforms, four membrane bound, and other three soluble isoforms that can suffer different posttranslational modifications or even complex formations. In addition, HLA-G has been described included in ex...

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;...

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...

To define whether individual human leukocyte antigen (HLA) class I allotypes are used preferentially in human cytomegalovirus (CMV)-specific cytotoxic T lymphocyte responses, CD8+ T cell responses restricted by up to six HLA class I allotypes in an individual were measured in parallel using K562-based artificial antigen-presenting cells expressing both CMV pp65 antigen and one of 32 HLA class I...

The human leukocyte antigen-B27 is one of the class I molecules of the major histocompatibility complex which is strongly associated with ankylosing spondylitis (AS). The strength of the disease association with B27 varies markedly among racial and ethnic populations. It is an allele family, which constitutes about 31 subtypes, with a considerable geographic and ethnic difference in distributio...
