Around 30% of individuals will develop herpes zoster (HZ), caused by the varicella zoster virus (VZV), during their life. While several risk factors for HZ, such as immunosuppressive therapy, are well known, the genetic and molecular components that determine the risk of otherwise healthy individuals to develop HZ are still poorly understood. We created a computational model for the Human Leukocyte Antigen (HLA-A, -B, and -C) presentation capacity of peptides derived from the VZV Immediate Early 62 (IE62) protein...

Previous research on the equine major histocompatibility complex (MHC) demonstrated strong correlations between haplotypes defined by polymorphic intra-MHC microsatellites and haplotypes defined using classical serology. Here, we estimated MHC diversity in a sample of 124 Arabian horses from an endangered strain native to Iran (Persian Asil Arabians), using a validated 10-marker microsatellite panel. In a group of 66 horses related as parent-offspring pairs or half-sibling groups, we defined 51 MHC haplotypes, 49 of which were new...

Dengue is the most prevalent arthropod-borne viral illness in humans worldwide. Single-nucleotide polymorphisms (SNPs) in genes involved in the immune response, such as dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN), IgG Fc receptor II-A (FcγRIIa), vitamin D receptor (VDR), and tumor necrosis factor alpha (TNF-α), were previously reported to be associated with susceptibility to dengue disease in different human populations. Therefore, due to the relevant association of host immune and genetic status with disease susceptibility/severity of dengue, this work aims to verify the frequency of anti-dengue virus antibodies and some dengue-associated risk SNPs in a population in Minas Gerais State, Southeast Brazil...

Bandicoots are omnivorous marsupials of the order Peramelemorphia. Conservation concerns and their unique biological characteristics suggest peramelomorphs are worthy research subjects, but knowledge of their genetics and immunology has lagged behind that of other high-profile marsupials. Here, we characterise the transcriptome of the long-nose bandicoot (Perameles nasuta), the first high-throughput data set from any peramelomorph. We investigate the immune gene repertoire of the bandicoot, with a focus on key immune gene families, and compare to previously characterised marsupial and mammalian species...

Objective Assimilation of SNPs Interacting in Synchrony (OASIS) is a locus-based clustering algorithm recently described that can potentially address false positives and negatives in genome-wide association studies (GWAS) of complex disorders. Diabetic nephropathy (DN) is incompletely understood due to a paucity of genes identified despite several GWAS. OASIS was applied to three DN dbGAP GWAS datasets (4725 subjects; 1.06 million SNPs). OASIS identified 19 DN genes which were verified using single variant replication in a standard association study and gene-based analysis using GATES...

Pig-tailed macaques (Macaca nemestrina, Mane) are important models for human immunodeficiency virus (HIV) studies. Their infectability with minimally modified HIV makes them a uniquely valuable animal model to mimic human infection with HIV and progression to acquired immunodeficiency syndrome (AIDS). However, variation in the pig-tailed macaque major histocompatibility complex (MHC) and the impact of individual transcripts on the pathogenesis of HIV and other infectious diseases is understudied compared to that of rhesus and cynomolgus macaques...

Regardless of sampling depth, accurate genotype imputation is limited in regions of high polymorphism which often have a heavy-tailed haplotype frequency distribution. Many rare haplotypes are thus unobserved. Statistical methods to improve imputation by extending reference haplotype distributions using linkage disequilibrium patterns that relate allele and haplotype frequencies have not yet been explored. In the field of unrelated stem cell transplantation, imputation of highly polymorphic human leukocyte antigen (HLA) genes has an important application in identifying the best-matched stem cell donor when searching large registries totaling over 28,000,000 donors worldwide...

In comparison to humans and chimpanzees, gorillas show low diversity at MHC class I genes (Gogo), as reflected by an overall reduced level of allelic variation as well as the absence of a functionally important sequence motif that interacts with killer cell immunoglobulin-like receptors (KIR). Here, we use recently generated large-scale genomic sequence data for a reassessment of allelic diversity at Gogo-C, the gorilla orthologue of HLA-C. Through the combination of long-range amplifications and long-read sequencing technology, we obtained, among the 35 gorillas reanalyzed, three novel full-length genomic sequences including a coding region sequence that has not been previously described...

In this study, a homolog of the TLR11 family gene from the sea urchin Strongylocentrotus intermedius (denoted as SiTLR11) was cloned and characterized. The full-length cDNA of SiTLR11 was 2096-bp long, which included 43 bp of 5' untranslated region (UTR), 238 bp of 3' UTR, and a putative open reading frame of 1815 bp encoding a polypeptide of 604 amino acid residues. Representative domains such as leucine-rich repeat (LRR) (residues 108-249) and a cytoplasmic Toll-interleukin-1 receptor (TIR) (residues 429-571) domains were detected in the predicted amino acid sequence of SiTLR11...

The domestic goat (Capra hircus) is an important ruminant species both as a source of antibody-based reagents for research and biomedical applications and as an economically important animal for agriculture, particularly for developing nations that maintain most of the global goat population. Characterization of the loci encoding the goat immune repertoire would be highly beneficial for both vaccine and immune reagent development. However, in goat and other species whose reference genomes were generated using short-read sequencing technologies, the immune loci are poorly assembled as a result of their repetitive nature...

The cluster of differentiation 4 (CD4) molecule functions as a co-receptor for MHC class II binding to TCR in T helper cells. A CD4 epitope deficiency was identified in the swine MeLiM (melanoblastoma-bearing Libechov minipig) strain, a model for spontaneous cutaneous melanoma development and regression. Extensive sequencing revealed a high genetic variability of CD4 and the existence of several haplotypes segregating in MeLiM. Forty polymorphisms were identified in the coding sequence, out of which 20 correspond to non-synonymous variants and 10 are located in the 3'UTR of CD4 transcripts...

The northern pig-tailed macaque (Macaca leonina) has been considered as an independent species from the pig-tailed macaque group. We have previously reported that this species macaque has the potential to be a useful animal model in HIV/AIDS pathogenesis and vaccine studies due to its susceptibility to HIV-1. To develop this animal into a potential HIV/AIDS model, we have studied the classical MHC genes of this animal. In this study, the non-classical MHC genes Malo-DM and Malo-DO alleles were first characterized by sequencing and cloning in 12 unrelated northern pig-tailed macaques...

The implementation of exome sequencing technologies has started to unravel the genetic etiology of familial multiple sclerosis (MS). A homozygote p.G587S mutation in NLRP1 has been suggested as potentially causative for the onset of MS in an affected sibling pair, who later developed malignant melanoma. To validate the proposed role of recessive NLRP1 mutations in the pathological mechanisms of MS, we examined exome sequencing data from 326 MS patients from Canada for the identification of NLRP1 missense and nonsense variants...

Susceptibility to malaria infection has been associated with host genetic polymorphisms that differs between groups. We hypothesize that Toll-interacting proteins (TOLLIP), vitamin D receptor (VDR) and tumor necrosis factor-α (TNF) genes are significant contributors to susceptibility and disease severity in Plasmodium falciparum (Pf) infection. Our aim is to explore the genomic diversity and haplotype frequency of these genes, as well as extrapolate possible association with markers of severity, between malaria-infected and healthy controls...

The current information on the polymorphism variation and haplotype structure of the domestic dog leukocyte antigen (DLA) genes is limited in comparison to other experimental animals. In this paper, to better elucidate the degree and types of polymorphisms and genetic differences for DLA-88, DLA-12 and DLA-64, we genotyped four families of 38 beagles and another 404 unrelated dogs representing 49 breeds by RT-PCR based Sanger sequencing. We also sequenced and analyzed the genomic organization of the DLA-88 and DLA-12 gene segments to better define these two-gene DLA haplotypes more precisely...

Exposure to neurotropic viruses, such as herpes simplex virus type 1 and human cytomegalovirus, has been reported to be associated with cognitive impairment in schizophrenia. These viruses have evolved highly sophisticated strategies for decreasing the efficacy of the host immune response and interfering with viral clearance. Particular immunoglobulin GM (γ marker) genotypes modulate these viral immunoevasion strategies, influence antibody responsiveness to viral proteins, and are also associated with susceptibility to schizophrenia, providing an excellent rationale for determining their possible involvement in the cognitive functions in this highly heritable neurodevelopmental disorder...

Dogs are an excellent model for human disease. For example, the treatment of canine lymphoma has been predictive of the human response to that treatment. However, an incomplete picture of canine (Canis lupus familiaris) immunoglobulin (IG) and T cell receptor (TR)-or antigen receptor (AR)-gene loci has restricted their utility. This work advances the annotation of the canine AR loci and looks into breed-specific features of the loci. Bioinformatic analysis of unbiased RNA sequence data was used to complete the annotation of the canine AR genes...

In sheep, the A and B loci encoding the α and β chains of the classical class II MHC molecules are DRA and DRB and DQA and DQB. Previous analyses described the duplication of the DQA and DQB genes. The majority of haplotypes include DQA1 and DQA2 loci, however, in a number of haplotypes, DQA1 appears absent and these haplotypes have been described as DQA1 null. In these haplotypes, the DQA2 locus is found in combination with a second locus which appeared more closely related to DQA2 than DQA1, hence the description of this locus as DQA2-like...

Influenza epidemics are a serious global public health and economic problem. The IFITM3 allele (rs12252-C) was suggested as a population-based genetic risk factor for severe influenza virus infection by A(H1N1)pdm09. We analyzed the population genetics of IFITM3 variants in the Portuguese general population (n = 200) and Central Africans (largely Angolan) (n = 148) as well as its association to influenza severity in Portuguese patients (n = 41). Seven SNPs, within the 352 bp IFITM3 amplicon around rs12252, were identified...
