The polymorphism of human leukocyte antigen (HLA), which is a genetic factor that influences the progression of hemorrhagic fever with renal syndrome (HFRS) after Hantaan virus (HTNV) infection, was incompletely understood. In this case-control study, 76 HFRS patients and 370 healthy controls of the Chinese Han population were typed for the HLA-A, -B, and -DRB1 loci. The general variation at th...

AIM To determine genetic polymorphisms at human leukocyte antigen (HLA)-A, -B, and -DRB1 loci in Han population of Xi'an city in China. METHODS Polymerase chain reaction-based reverse line-strip sequence specific oligonucleotide hybridization was used to determine the alleles of HLA-A, -B, and -DRB1 in 516 unrelated, healthy individuals of Han population in Xi'an. Allele frequencies at HLA-A,...

In this study, we aimed to explore the associations between HLA-A\B\DRB1 polymorphisms and the risks of vulvar lichen sclerosus (VLS) or squamous cell hyperplasia of the vulva (SCHV) in Han Chinese women. We enrolled 76 Han Chinese women with VLS (Group A), 74 with SCHV (Group B), and 66 healthy women (control group) in this study. Polymerase chain reaction amplification with sequence specific ...

background: human t cell lymphotropic virus type i (htlv-i)-associated myelopa-thy/tropical spastic paraparesis (ham/tsp) is an inflammatory disease which occurs in less than 2% of htlv-i -infected individuals. high proviral load, high htlv-i-specific cd8+ cytotoxic t lymphocyte frequency (ctl) and host genetic factors such as hla all appear to be associated with htlv-i infection. previous stud...

Background Following the launch of global COVID-19 vaccination campaign, there have been increased reports autoimmune diseases developing de novo following vaccination. These cases include rheumatoid arthritis, hepatitis, immune thrombotic thrombocytopenia, and connective tissue diseases. Nevertheless, vaccines are considered safe for patients with strongly recommended. Objectives The aim this ...

Background: Anti-citrullinated protein antibody (ACPA) production is observed in several organs even prior to the onset of rheumatoid arthritis (RA), and oral mucosa considered be one important tissues. Saliva reflect microbiota(oralMB) including periodontal disease. A gene-environment interaction between cigarette smoking shared epitope genes HLA-DRB1*shared (SE) provides a high risk ACPA-posi...

OBJECTIVE HLA-DRB1*16:35 is a low incidence allele in the HLA-DRB1 locus. The objective of this study is to report the ethnicity of DRB1*16:35 and its deduced probable HLA associated haplotype in two Taiwanese unrelated bone marrow hematopoietic stem cell donors and to determine its variation from DRB1*16:02:01 and DRB1*16:01:01. MATERIALS AND METHODS A sequence-based typing method was employ...

Increasing evidences indicate that the abnormal DNA methylation is involved in the pathogenesis of psoriasis. A number of SNPs in HLA-DRB1 have been found being associated with the risk of psoriasis, however it is unclear that metylation status within HLA-DRB1 in psoriasis. Here, DNA and RNA were obtained from epidermis of 56 patients with plaque psoriasis and 28 healthy volunteers served as th...

The current coronavirus disease 2019 (COVID-19) pandemic that is caused by the severe acute respiratory syndrome 2 (SARS-CoV-2) has a significant threat to public health. Although vaccines based on mRNA of SARS-CoV-2 spike protein have been developed induce both cellular and humoral immunity against SARS-CoV-2, there some concerns raised about their high cost, particularly in developing countri...
