the association of hla class ii genes with ulcerative colitis (uc) as an autoimmune disease has been investigated for several years. however, factors responsible for genetic predisposition of this disease have so far not been clearly understood. in this study, for the first time, we aimed to investigate the association between hla-drb1 types and uc in the population of kerman, a city southeast ...

Background . Molecules of the major histocompatibility complex in cancer are currently being widely studied, and their clinical significance is still subject controversy. It reported that they might have an important predictive value effectiveness immunotherapy. The study expression HLA molecules status breast provides a deeper understanding biological properties tumor, particular to identify f...

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...

background hepatitis b virus (hbv) infection is a serious public health problem in china and worldwide. mother-to-child transmission is one of hbv’s main transmission routes in highly endemic regions. genome-wide association studies (gwas) identify single nucleotide polymorphisms (snps) at hla loci as associated with hbv infection. however, the mechanisms of hbv perinatal transmission and break...

objective: hla-g is a nonclassical major histocompatibility complex antigen and is expressed as seven isoforms, including four membrane bound (hla-g1 to –g4) and three soluble (hla-g5 to –g7) forms. the pattern of selective expression of hla-g transcripts in tissues shows the existence of a tight transcriptional control on the gene expression. it has been revealed that cytokines including inter...

Background: The Human Leukocyte Antigen (HLA) is the most polymorphic region in human genome. Moreover, HLA haplotype frequencies are largely used in transplantation, the treatment of autoimmune diseases, and population-based studies. The present study aimed to determine HLA-A, -B, -DR alleles and haplotype frequencies in 88 unrelated donors of Iranian Gilak ethnic group, by Polymerase Chain Re...

Severe cutaneous adverse drug reaction (SCAR) is considered to be a multifactorial drug side effect. This study was designed to investigate the epidemiology and human leukocyte antigen (HLA)-A and -B gene polymorphisms in pediatric patients with SCAR admitted in tertiary referral center, southwestern of Iran from 2013 to 2017. Demographic data, past allergy and autoimmune history, clinical pres...
