Tumour necrosis factor (TNF)-mediated signalling plays a key role in inflammatory and neurodegenerative processes leading to the development of multiple sclerosis (MS). Recent studies have highlighted the role of tumour necrosis factor receptor superfamily member 1A (TNFRSF1A) gene encoding the type 1 TNF receptor in the genetic predisposition to MS. This study aimed to validate the association of TNFRSF1A rs1800693 and rs4149584 polymorphisms with susceptibility to MS in the Slovak population and analyse their influence on age at disease onset, severity, and disability progression...

Natural killer (NK) cells recognize targets that have been changed via malignant transformation or infection. Previously, NK cells were thought to be short-lived, but we now know that NK cells can be long-lived and remember past exposures in response to CMV. NK cells use a plethora of activating and inhibitory receptors to recognize these changes and attack targets, but tumour cells often evade NK cells. Therefore, major efforts are being made to hone in on NK cell antitumour properties in immunotherapy. In the clinical setting, haploidentical NK cells can be adoptively transferred to help treat cancer...

The distribution of human leucocyte antigen (HLA) allele and haplotype varied among different ethnic populations. In this study, we investigated the allele and haplotype frequencies of HLA-A, HLA-B and HLA-DRB1 loci in the Nanning Han population who live in Guangxi province of China. We identified 26 HLA-A, 56 HLA-B and 31 HLA-DRB1 alleles in 562 Nanning individuals of Han ethnic group by sequence-based typing method. Of these, the three most common alleles in HLA-A, HLA-B and HLA-DRB1 loci, respectively, were A*11:01 (32...

The human leucocyte antigen (HLA) is the most polymorphic region of the human genome. Compared with Sanger-sequencing-based typing (SBT) methods, next-generation sequencing (NGS) has significantly higher throughput and depth sequencing characteristics, having dramatic impacts on HLA typing in clinical settings. Here, we performed NGS technology with Ion Torrent S5 platform to evaluate the potential four novel HLA alleles detected in five donors from Chinese Marrow Donor Program (CMDP, Shaanxi Province) during routine Sanger SBT testing...

HLA-G is a nonclassical Class I major histocompatibility complex (MHC) gene. This gene has a limited protein alteration that is produced by alternative splicing and can be important in the preservation of pregnancy. Recent findings suggest that alteration in HLA-G gene expression can lead to pregnancy failure, such as recurrent pregnancy loss (RPL). As the promoter SNPs of the gene may impact the HLA-G expression levels, the study of these SNPs is very important. In this study, for the promoter region of HLA-G gene in the case group (100 women with a history of two or more repeated miscarriages) and the control group (100 women with at least two successful pregnancies), PCR reaction was performed...

The major histocompatibility complex (MHC) molecule plays an important role in the vertebrate immune system. However, we have a limited understanding of the MHC genomic structure in teleosts. Using gene cloning and family analysis, we isolate the MHC class II genes in the tongue sole (Cynoglossus semilaevis) and find that both class II A and class II B genes are duplicated (named Cyse-DAA and Cyse-DBA, Cyse-DAB and Cyse-DBB, respectively). The class II A genes consist of four exons with a highly conserved genomic structure, but each gene has unique and defining exon 2 and intron 2 sequences...

The development of techniques to define the human leucocyte antigen (HLA) region has proven to be challenging due to its high level of polymorphism. Within a clinical laboratory, a technique for high-resolution HLA typing, which is rapid and cost effective is essential. NGS has provided a rapid, high-resolution HLA typing solution, which has reduced the number of HLA ambiguities seen with other typing methods. In this study, the One Lambda NXType NGS kit was tested on the Ion Torrent PGM platform. A total of 362 registry donors from four ethnic populations (Europeans, South Asians, Africans and Chinese) were NGS HLA typed across 9-loci (HLA-A, -B, -C, -DRB1,-DRB345 -DQB1 and -DPB1)...

This study aimed to investigate the genetic basis of ankylosing spondylitis (AS) and polyarthralgia (PA) conditions among Indian subjects through genotyping two immune regulatory genes CD14 (-159C>T) and MIF (-173G>C) and find their association with the expression levels of three circulating inflammatory miRNAs. This investigation may provide early genetic cause of these two forms of arthritis and more optimal biological targets to predict early therapeutic outcomes. A total of 140 patients (AS: 70 and PA: 70) and 156 controls were recruited from Indian population...

A novel allelic variant in HLA-B*40 lineage, HLA-B*40:298:02, has been identified in an individual of Han ethnicity afflicted with nasopharyngeal carcinoma in Hunan province, southern China. Following polymerase chain reaction-Sanger sequence-based typing (PCR-SBT), this new variant was further confirmed by two distinct strategies of cloning and sequencing. HLA-B*40:298:02 differs from HLA-B*40:298:01 by a single synonymous cytosine substitution at nucleotide position 26 (T→C) in exon 3, which corresponds to codon 99 of the mature HLA-B mRNA molecule...

Mannan-binding lectin (MBL) and MBL-associated serine protease 2 (MASP-2) are components of the lectin pathway, which activate the complement system after binding to the HCV structural proteins E1 and E2. We haplotyped 11 MASP2 polymorphisms in 103 HCV patients and 205 controls and measured MASP-2 levels in 67 HCV patients and 77 controls to better understand the role of MASP-2 in hepatitis C susceptibility and disease severity according to viral genotype and fibrosis levels. The haplotype block MASP2*ARDP was associated with protection against HCV infection (OR = 0...

Ankylosing spondylitis (AS) is a complex inflammatory disease that represents a major health problem both in Algeria and worldwide. Several lines of evidence support that genetic risk factors play a role in AS etiology and the CTLA4 gene has attracted a considerable attention. In this study, we were interested in evaluating the HLA-B27 frequency and in exploring the CTLA4 gene in a sample of the North African population. The dataset of the current study is composed of 81 patients with AS and 123 healthy controls...

The Tie2 receptor is an important player in angiogenesis. The Tie2 mRNA and protein are abundantly expressed in the lungs and the associated pathway also has an important role in the development and function of the eye. Tie2 is encoded by the TEK gene in humans. Recently, variations in the TEK gene have been found associated with asthma. The objective of the present study was to investigate whether variations in the TEK gene influenced the susceptibility to pediatric asthma and/or associated phenotypes like GINA status, viral- or exercise-induced asthma, allergic asthma, indoor, outdoor, inhalative allergies, IgE and eosonophil levels, allergic rhinitis and allergic conjunctivitis...

Differential expression of HLA-DQA1 and HLA-DQB1 gene alleles was analysed in three different cell populations isolated from peripheral blood-B lymphocytes, monocytes and whole-blood cells. Interallelic differences in mRNA levels were observed: DQA1*03 alleles were among the most expressed in all cell types, whereas DQA1*05 alleles were least expressed in whole blood and monocytes and among the most expressed in B cells. For DQB1 gene, DQB1*06 group of alleles were the most expressed, and DQB1*02 group the least expressed within all cell populations examined...

We reported previously on the widespread occurrence of anti-HLA alloantibodies of the IgA isotype (anti-HLA IgA) in the sera of solid-organ re-transplantation (re-tx) candidates (Arnold et al., ). Specifically focussing on kidney re-tx patients, we now extended our earlier findings by examining the impact of the presence and donor specificity of anti-HLA IgA on graft survival. We observed frequent concurrence of anti-HLA IgA and anti-HLA IgG in 27% of our multicenter collective of 694 kidney re-tx patients...

Three new HLA class I alleles were described in the Spanish population. HLA-A*68:169 and -B*39:129 show one amino acid replacement at the α1-domain, compared to A*68:02 (P47 > L47) and -B*39:06 (S11 > A11), respectively. HLA-B*07:298 presents one nucleotide mutation within exon 1, resulting in a new amino acid position -14, L>Q, which has not been previously described in any HLA protein. Prediction of the B*07:298 signal peptide cleavage did not show significant differences in comparison with that obtained for the rest of HLA-B genes...
