The aim of the present study was to identify influenza A-derived peptides which bind to both HLA class I and -II molecules and by immunization lead to both HLA class I and class II restricted immune responses. Eight influenza A-derived 9-11mer peptides with simultaneous binding to both HLA-A*02:01 and HLA-DRB1*01:01 molecules were identified by bioinformatics and biochemical technology. Immuniz...

A substantial genetic contribution to systemic lupus erythematosus (SLE) risk is conferred by major histocompatibility complex (MHC) gene(s) on chromosome 6p21. Previous studies in SLE have lacked statistical power and genetic resolution to fully define MHC influences. We characterized 1,610 Caucasian SLE cases and 1,470 parents for 1,974 MHC SNPs, the highly polymorphic HLA-DRB1 locus, and a p...

background: papillon-lefevre syndrome (pls) is a rare autosomal recessive disorder characterized by diffused palmoplantar keratoderma and severe periodontitis. increased susceptibility to infections due to impairment of the immune system is considered to be involved in pathoetiology of this disease. objective: according to the crucial function of hla molecules in immune responses and associatio...

background: the human leukocyte antigen (hla) matching between organ donor and recipient is an acceptable strategy in clinical transplantation since 1964. however, in bone marrow transplantation, finding matched donors is often problematic. thus new method for down regulation of hla can be an alternative strategy to solve this problem. objective: to examine the effect of serum starvation on hla...

BACKGROUND In Caucasian populations, the tumor cells of Epstein Barr virus (EBV)-positive classical Hodgkin Lymphomas (cHL) patients more frequently express HLA class I and HLA class II molecules compared to EBV-negative cHL patients. HLA expression (in relation to EBV) in Asian cHL patients has not been previously investigated. METHODOLOGY/PRINCIPAL FINDINGS We randomly selected 145 cHL pati...

CD8+ T cells are thought to play an important role in protective immunity to tuberculosis. The major histocompatibility complex class I subtype HLA-A*0201 is one of the most prevalent class I alleles, with a frequency of over 30% in most populations. HLA-A*0201 transgenic, H-2Db/mouse beta2-microglobulin double-knockout mice (HHD) which express human HLA-A*0201 but no mouse class I, was shown t...

Purpose: Glioblastoma (GBM) shows downregulated expression of human leukocyte antigen (HLA) class I, thereby escaping from cytotoxic T cells and limiting the efficacy of immunotherapy. Loss of heterozygosity (LOH) of HLA class I (6p21) and/or b-2 microglobulin (B2m) (15q21) regions represents irreversible downregulation. In this study, we examined the prevalence of these LOH events and their re...

PURPOSE Glioblastoma (GBM) shows downregulated expression of human leukocyte antigen (HLA) class I, thereby escaping from cytotoxic T cells and limiting the efficacy of immunotherapy. Loss of heterozygosity (LOH) of HLA class I (6p21) and/or β-2 microglobulin (B2m) (15q21) regions represents irreversible downregulation. In this study, we examined the prevalence of these LOH events and their rel...

the hla class ii genes of human major histocompatibility complex (mhc) exhibit an extensive degree of genetic polymorphism. this region subdivides into four sub-regions dp, do, dq, and dr. there are five different dr haplotypes that all contain a highly polymorphic allele called hla-drb1. in most recent studies, the association between hla-drb1 and a large number of diseases such as multiple sc...
