The ontogeny of the natural, public IgM repertoire remains incompletely explored. Here, high-resolution immunogenetic analysis of B cells from (unrelated) fetal, child, and adult samples, shows that although fetal liver (FL) and bone marrow (FBM) IgM repertoires are equally diversified, FL is the main source of IgM natural immunity during the 2nd trimester. Strikingly, 0.25% of all prenatal clonotypes, comprising 18.7% of the expressed repertoire, are shared with the postnatal samples, consistent with persisting fetal IgM+ B cells being a source of natural IgM repertoire in adult life...

OBJECTIVE: HLA-DPB1 matching may impact allogeneic hematopoietic stem cell transplantation (ASCT) outcomes; however, this locus is not in linkage disequilibrium with the remainder of the HLA genes. After classifying HLA-DPB1 mismatches based on T-cell epitope, avoiding non-permissive mismatches may impact survival. We tested this hypothesis at a single academic institution. METHODS: Retrospective HLA-DPB1 genotyping was performed on 153 adult patients who underwent ASCT and unrelated donors matched for HLA-A, B, C, DRB1 and DQB1 loci (10/10)...

The outcome of hepatitis B virus (HBV) infection is considered to be related to the host immunogenetic susceptibility. B cell activating factor (BAFF) is involved in both B cell and T cell mediated immunity and its circulating levels were shown to be significantly elevated in HBV-related liver diseases. This study examined BAFF rs9514828 and rs12583006 polymorphisms in 386 patients with various liver diseases related to chronic HBV infection, 69 HBV infection resolvers, and 191 healthy controls. Both rs9514828 and rs12583006 polymorphisms and serum BAFF levels were determined in 232 patients with chronic HBV infection, and 61 healthy controls...

T-cell acute lymphoblastic leukemia (T-ALL) results from leukemic transformation of T-cell precursors arrested at specific differentiation stages, including an 'early-cortical' thymic maturation arrest characterized by expression of cytoplasmic TCRβ but no surface TCR and frequent ectopic expression of the TLX1/3 NK-Like homeotic proteins (NKL). We designed a TCRα VJC PCR to identify clonal TCRα rearrangements in 32% of 127T-ALLs, including 0/52 immature/TCRγδ lineage cases and 41/75 (55%) TCRαβ lineage cases...

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by dysfunctions in social interactions resulting from a complex interplay between immunogenetic and environmental risk factors. Autoimmunity has been proposed as a major etiological component of ASD. Whether specific autoantibodies directed against brain targets are involved in ASD remains an open question. Here, we identified within a cohort an ASD patient with multiple circulating autoantibodies, including the well-characterized one against glutamate NMDA receptor (NMDAR-Ab)...

Many fishes express high levels of intraspecific variability, often linked to resource partitioning. Several studies show that a species' evolutionary trajectory of adaptive divergence can undergo reversals caused by changes in its environment. Such a reversal in neutral genetic and morphological variation among lake trout Salvelinus namaycush ecomorphs appears to be underway in Lake Superior. However, a water depth gradient in neutral genetic divergence was found to be associated with intraspecific diversity in the lake...

The aim of the present study was to estimate the relative contribution of immunogenetic and microbiological factors in the development of recurrent tonsillitis in a Mexican population. Patients (n = 138) with recurrent tonsillitis and an indication of tonsillectomy (mean age: 6.05 years ± 3.00; median age: 5 years, female: 58; age range: 1-15 years) and 195 non-related controls older than 18 years and a medical history free of recurrent tonsillitis were included. To evaluate the microbial contribution, tonsil swab samples from both groups and extracted tonsil samples from cases were cultured...

Chronic idiopathic neutropenia (CIN) is an acquired disorder of granulopoiesis characterized by female predominance and mostly uncomplicated course. Crucial to CIN pathophysiology is the presence of activated T lymphocytes with myelosuppressive properties in both peripheral blood (PB) and bone marrow (BM). We systematically profiled the T cell receptor beta chain (TRB) gene repertoire in CD8(+) cells of 34 CIN patients through subcloning/Sanger sequencing analysis of TRBV-TRBD-TRBJ gene rearrangements. Remarkable repertoire skewing and oligoclonality were observed, along with shared clonotypes between different patients, alluding to antigen selection...

INTRODUCTION: A constant interest to explore NUC is caused by the global trend showing a rise in colitis mobidity rate. According to a series of epidemiological studies, the highest incidence of NUC occurs in young age groups, which leads to significant loss of working capacity and high level of incapacitation. One of the leading roles in the pathogenesis of this disease is reportedly played by immunogenetic theory. To date, the main practical technique of NUC diagnostics is colonoscopy...

PURPOSE OF REVIEW: Next-generation sequencing (NGS) has now been established, and widely recognized, to be the preferred choice for human leukocyte antigen (HLA) typing. This transformation is based upon the many scientific, operational and economic benefits this technology affords. In this report, we review the major advantages, existing limitations and significant promise derived from adopting this technology in immunogenetics. RECENT FINDINGS: Significant benefits have emerged from the usage of NGS in a relatively short period, whereby we realize that this technology not only helps addressing the technical and operational problems we have had with the legacy methods for HLA typing, but equally important, it also allows for creative applications in stem cell and organ transplantation, new ways to investigate associations of the major histocompatibility complex (MHC) with many diseases and enhance our understanding regarding the MHC and non-MHC genomic interactions...

The advantages of chicken (Gallus gallus domesticus) antibodies as immunodiagnostic and immunotherapeutic biomolecules has only been recently recognized. Even so, chicken antibodies remain less-well characterized than their mammalian counterparts. This review aims at providing a current overview of the structure, function, development and generation of chicken antibodies. Additionally, brief but comprehensive insights into current knowledge pertaining to the immunogenetic framework and diversity-generation of the chicken immunoglobulin repertoire which have contributed to the establishment of recombinant chicken mAb-generating methods are discussed...

BACKGROUND: Several recent studies showed that next-generation sequencing (NGS)-based human leukocyte antigen (HLA) typing is a feasible and promising technique for variant calling of highly polymorphic regions. To date, however, no method with sufficient read depth has completely solved the allele phasing issue. In this study, we developed a new method (HLAscan) for HLA genotyping using NGS data. RESULTS: HLAscan performs alignment of reads to HLA sequences from the international ImMunoGeneTics project/human leukocyte antigen (IMGT/HLA) database...

HLA-G is a nonclassical HLA immunotolerogenic molecule expressed in different human cell types. Successful embryo implantation is a consequence of information exchange between the uterus and the blastocyst. It is widely accepted that HLA-G expression by the fetus promotes the establishment of several mechanisms that, ultimately, would protect the developing embryo from maternal immune rejection and seems to be essential to both an adequate implantation and a healthy pregnancy. MicroRNAs miR-148a and miR-152 down-regulate HLA-G expression...

Recurrent pregnancy loss (RPL) is defined as three or more consecutive pregnancy losses, and it affects 2-3% of couples trying to conceive. RPL is a multifactorial disorder, and only few evidence-based treatments are available. It is associated with an increased prevalence of stress and major depression, and also with immunogenetic markers, autoimmunity and an increase of the risk of cardiovascular disease in later life. Immunology seems to be a key element in RPL, and further research is needed to understand the pathogenesis of this heterogeneous condition in order to develop personalized treatment...

To obtain insight into the ontogeny of mantle cell lymphoma (MCL), we assessed 206 patients from a morphological, immunohistochemical, and immunogenetic perspective. Our series included nodal (n = 151), extranodal (n = 28), and primary splenic (n = 27) MCL cases. Skewing of the immunoglobulin heavy variable (IGHV) gene repertoire was noted, with only four IGHV genes accounting for 46% of cases and approximately 70% of cases (107/154) bearing an imprint of somatic hypermutation (SHM) ranging from minimal to pronounced...

Analysis and interpretation of Ig and TCR gene rearrangements in the conventional, low-throughput way have their limitations in terms of resolution, coverage, and biases. With the advent of high-throughput, next-generation sequencing (NGS) technologies, a deeper analysis of Ig and/or TCR (IG/TR) gene rearrangements is now within reach, which impacts on all main applications of IG/TR immunogenetic analysis. To bridge the generation gap from low- to high-throughput analysis, the EuroClonality-NGS Consortium has been formed, with the main objectives to develop, standardize, and validate the entire workflow of IG/TR NGS assays for 1) clonality assessment, 2) minimal residual disease detection, and 3) repertoire analysis...

Antigen Receptor Galaxy (ARGalaxy) is a Web-based tool for analyses and visualization of TCR and BCR sequencing data of 13 species. ARGalaxy consists of four parts: the demultiplex tool, the international ImMunoGeneTics information system (IMGT) concatenate tool, the immune repertoire pipeline, and the somatic hypermutation (SHM) and class switch recombination (CSR) pipeline. Together they allow the analysis of all different aspects of the immune repertoire. All pipelines can be run independently or combined, depending on the available data and the question of interest...
