Journal description

The Journal of Immunological Methods is devoted to covering techniques for: (1) Quantitating and detecting antibodies and/or antigens and haptens based on antigen-antibody interactions. (2) Fractionating and purifying immunoglobulins, lymphokines and other molecules of the immune system. (3) Isolating antigens and other substances important in immunological processes. (4) Labelling antigens and antibodies with radioactive and other markers. (5) Localizing antigens and/or antibodies in tissues and cells, in vivo or in vitro. (6) Detecting, enumerating and fractionating immunocompetent cells. (7) Assaying for cellular immunity. (8) Detecting cell-surface antigens by cell-cell interactions. (9) Initiating immunity and unresponsiveness. (10) Transplanting tissues. (11) Studying items closely related to immunity such as complement, reticuloendothelial system and others. In addition the journal will publish articles on novel methods for analysing the organization, structure and expression of genes for immunologically important molecules such as immunoglobulins, T cell receptors and accessory molecules involved in antigen recognition, processing and presentation. Submitted full length manuscripts should describe new methods of broad applicability to immunology and not simply the application of an established method to a particular substance - although papers describing such applications may be considered for publication as a short Technical Note The Recombinant Technology section will contain articles relating to modification by recombinant techniques of molecules of immunological interest; isolation of novel binding proteins by phage display; gene therapy; transfection; and expression. Immunology Protocols is a section providing detailed, step-by-step descriptions of new and established techniques in immunology. Articles on the molecular biological analysis of immunologically relevant receptor binding sites are also invited.

    ABSTRACT: Severely immunodeficient mice such as the NOD/SCID/IL2rγ(null) (NSG) strain can be engrafted with human hematopoietic stem cells (HSCs), resulting in chimeric mice containing many components of the human immune system (Human Immune System mice or HIS mice). HIS mice can both support the replication of and recapitulate much of the immunological response to a variety of pathogens, including ones with strict human tropism, such as HIV-1. In an effort to develop a better mouse model for human infectious pathogen infection and possible immune resolution, we compared the human immune system reconstitution of NSG mice following injection with human CD34+ HSCs purified from either fetal liver (FL) or umbilical cord blood (UCB). We analyzed reconstitution in standard NSG mice as well as a derivative of these mice containing an HLA.A2 encoding transgene (NSG.A2). HSCs from both sources effectively reconstituted hematopoietic lineages when injected into NSG mice. In marked contrast, total CD45(+) human hematopoietic cells in NSG.A2 mice were well reconstituted by HSCs from UCB but very poorly by HSCs purified from FL. Moreover, the reconstitution of T cell lineages in NSG.A2 mice by HSCs from UCB was inferior to that obtained using NSG mice. We also found that FL CD34(+) HSCs contain a much higher percentage of cells with a phenotype consistent with primitive progenitors than UCB HSCs. We discuss possible explanations for the influence of the HLA.A2 transgene on hematopoietic reconstitution using the two sources of HSCs. Copyright © 2015. Published by Elsevier B.V.

    ABSTRACT: Recently the analytical power of the latest high throughput next generation DNA sequencing platforms has been used to analyse phage that have been selected from the panning of large combinatorial libraries displaying either peptide or antibody ligands. This process, commonly referred to as next generation phage display (NGPD), allows the researcher to determine the identity of specific phage that are being enriched against an antigen target by analysis of the DNA sequence encoding the displayed ligand. This method bypasses several steps in conventional phage panning that include laborious colony picking and functional ligand screening. A downside of this approach is that the only output from such experiments is the DNA sequence information of such enriched phage particles. In the case of peptides, the peptide sequence can be synthesised directly and used for further screening, however this is more difficult with larger antibody fragments such as ScFvs. In the case of ScFvs, their coding sequence would have to be fully elucidated, synthesised and re-cloned before expression. We describe here the application of an inverse PCR-ligation methodology that enables the specific recovery of ScFvs of interest from enriched sub-libraries of phage clones. Phagemid particles are recovered using sequence information derived from their unique heavy chain CDR3/FR4 domains and specific clones can be recovered irrespective of CDR3 size and at levels of abundance that would be refractory to their discovery during conventional phage panning and screening.

    ABSTRACT: A rabbit monoclonal antibody (Abcam ab124797), with high affinity for a synthetic peptide corresponding to the C-terminal region of the receptor activator of nuclear factor (NF)-κB ligand (RANKL), specifically recognizes a 37 kDa protein by immunoblotting, in good agreement with the molecular mass of RANKL. However, our mass spectroscopy analysis revealed that the protein recognized by the antibody is the α-subunit of NAD(+)-dependent isocitrate dehydrogenase (ICDH), a key Krebs cycle enzyme in mitochondria. Consistently, immunocytochemical staining with the antibody revealed a network organization characteristic of mitochondria, which overlapped with staining by MitoTracker and was lost after the siRNA-mediated downregulation of ICDH. The C-terminal peptide of ICDH contains similar chemical characteristics to that of the RANKL peptide and interacts with the antibody, although the affinity is a hundred times weaker. The present study provides an example of the preferential recognition of a surrogate protein by a rabbit monoclonal antibody. Copyright © 2015. Published by Elsevier B.V.

    ABSTRACT: The study aimed to evaluate cell surface mobilisation of CD107a as a general activation marker on chicken cytotoxic T cells (CTL). Experiments comprised establishment of an in vitro model for activation induced CD107a mobilisation and design of a marker panel for detection of CD107a mobilisation on chicken CTL isolated from different tissues. Moreover, CD107a mobilisation was analysed on CTL isolated from airways of infectious bronchitis virus (IBV) infected birds direct ex vivo and upon in vitro stimulation. Results showed that phorbol 12-myristate 13-acetate (PMA) in combination with ionomycin was a consistent inducer of CD107a cell surface mobilisation on chicken CTL in a 4h cell culture model. In chickens experimentally infected with IBV, a higher frequency of CTL isolated from respiratory tissues were positive for CD107a on the cell surface compared to those from uninfected control chickens indicating in vivo activation. Moreover, upon in vitro PMA+ionomycin stimulation higher proportions of CTL isolated from the airways of IBV infected chickens showed CD107a mobilisation compared to those from uninfected control chickens. Monitoring of CD107a cell surface mobilisation may thus be a useful tool for studies of chicken CTL cytolytic potential both in vivo and in vitro. Copyright © 2015. Published by Elsevier B.V.

    ABSTRACT: Cut points in immunogenicity assays are used to classify future specimens into anti-drug antibody (ADA) positive or negative. To determine a cut point during pre-study validation, drug-naive specimens are often analyzed on multiple microtiter plates taking sources of future variability into account, such as runs, days, analysts, gender, drug-spiked and the biological variability of un-spiked specimens themselves. Five phenomena may complicate the statistical cut point estimation: i) drug-naive specimens may contain already ADA-positives or lead to signals that erroneously appear to be ADA-positive, ii) mean differences between plates may remain after normalization of observations by negative control means, iii) experimental designs may contain several factors in a crossed or hierarchical structure, iv) low sample sizes in such complex designs lead to low power for pre-tests on distribution, outliers and variance structure, and v) the choice between normal and log-normal distribution has a serious impact on the cut point. We discuss statistical approaches to account for these complex data: i) mixture models, which can be used to analyze sets of specimens containing an unknown, possibly larger proportion of ADA-positive specimens, ii) random effects models, followed by the estimation of prediction intervals, which provide cut points while accounting for several factors, and iii) diagnostic plots, which allow the post hoc assessment of model assumptions. All methods discussed are available in the corresponding R add-on package mixADA. Copyright © 2015 Elsevier B.V. All rights reserved.

    ABSTRACT: T lymphocyte migration is crucial for adaptive immunity. Manipulation of signaling molecules controlling cell migration combined with in-vitro cell migration analysis provides a powerful research approach. Microfluidic devices, which can precisely configure chemoattractant gradients and allow quantitative single cell analysis, have been increasingly applied to cell migration and chemotaxis studies. However, there are a very limited number of published studies involving microfluidic migration analysis of genetically manipulated immune cells. In this study, we describe a simple microfluidic method for quantitative analysis of T cells expressing transfected chemokine receptors and other cell migration signaling probes. Using this method, we demonstrated chemotaxis of Jurkat transfectants expressing wild-type or C-terminus mutated CCR7 within a gradient of chemokine CCL19, and characterized the difference in transfectant migration mediated by wild-type and mutant CCR7. The EGFP-tagged CCR7 allows identification of CCR7-expressing transfectants in cell migration analysis and microscopy assessment of CCR7 dynamics. Collectively, our study demonstrated the effective use of the microfluidic method for studying CCR7 mediated T cell transfectant migration. We envision this developed method will provide a useful platform to functionally test various signaling mechanisms at the cell migration level. Copyright © 2015. Published by Elsevier B.V.

    ABSTRACT: Bioanalytical data from early human studies conducted in normal volunteers are often used for building pharmacokinetic/pharmacodynamic models that can predict outcomes of future studies in diseased patients. Thus, it's important to develop and validate reliable and accurate bioanalytical assays that instill confidence that the intended therapeutic species (total or free) are being measured. Assays quantifying the free therapeutic species, the partially bound (for multivalent therapeutics) and unbound species, require much more characterization than assays that quantify the total therapeutic species. We have developed an immunoassay to measure free BMS-962476, an Adnectin protein therapeutic against soluble proprotein convertase subtilisin kexin (PCSK)-9, and performed an in-depth characterization of the accuracy of this assay with the assistance of modeling. The experimental data correlates with modeled data within 15% at all clinically relevant levels of PCSK9 in normal and diseased populations. Copyright © 2015. Published by Elsevier B.V.

    ABSTRACT: Citrobacter rodentium is a natural mouse pathogen which reproducibly infects mice and causes intestinal disease. The C. rodentium model of infection is very useful for investigating host-pathogen immune interactions in the gut, and can also be used to understand the pathogenesis of several important human intestinal disorders, including Crohn's disease, ulcerative colitis, dysbiosis and colon tumorigenesis. Both innate and adaptive immune responses play a critical role in protection against C. rodentium. Here, we summarize the role of immune components in protection against C. rodentium and describe techniques for the analysis of innate and adaptive mucosal immune responses, including setting up the infection, analysis of colonic hyperplasia and bacterial dissemination, evaluation of antibody responses, and purification and analysis of intestinal epithelial and lymphoid cells.

    ABSTRACT: Immunoconjugates that deliver cytotoxic payloads to cancer cells represent a promising class of therapeutic agents which are intensively investigated in various clinical applications. Prerequisites for the generation of effective immunoconjugates are antibodies which efficiently deliver the respective cytotoxic payload. To facilitate the selection of human or mouse antibodies that display favorable characteristics as immunotoxins, we developed a novel Pseudomonas exotoxin A (ETA)-based screening protein. The α-Fc-ETA' consists of a multispecies-specific Fc-binding domain antibody genetically fused to a truncated ETA version (ETA'). α-Fc-ETA' non-covalently bound to human and mouse antibodies but did not form immune complexes with bovine immunoglobulins. In combination with antibodies harboring human or mouse Fc domains α-Fc-ETA' inhibited proliferation of antigen-expressing tumor cells. The cytotoxic effects were strictly antibody dependent and were observed with low α-Fc-ETA' concentrations. Mouse antibodies directed against CD7 and CD317/HM1.24 that previously had been used for the generation of functional recombinant immunotoxins, also showed activity in combination with α-Fc-ETA' by inhibiting growth of antigen-positive myeloma and leukemia cell lines. In contrast, α-kappa-ETA', a similarly designed human kappa light chain-specific fusion protein, was only specifically active in combination with antibodies containing a human kappa light chain. Thus, the novel α-Fc-ETA' fusion protein is broadly applicable in screening antibodies and Fc-containing antibody derivatives from different species to select for candidates with favorable characteristics for immunotoxin development.

    ABSTRACT: Specimen collection method and quality insurance is pivotal in biomarker discovery. Pre-analytical variables concerning blood collection and sample handling might affect analytical results and should be standardised prior application. In this study, we examine pre-analytical characteristics of blood samples using protein microarray. The influences of 1) standby times until centrifugation (1h, 4h, 24h and 48h), 2) four blood collection methods, and 3) IgG purified from those samples on differentially reactive antigens between samples ("DIRAGs") were investigated. Spearman correlation analyses of intra-individual arrays demonstrated remarkable differences (0.75-0.98 vs. 0.5-0.75) of antibody reactivities within and between serum and plasma samples. Class comparison showed that reactive antigen profiles were best preserved using IgG purified samples of serum tubes without separation gel as after 24hours 83% of the 1h baseline DIRAGs were re-found. Testing dilution series with protein microarrays and Luminex xMap® Technology, we found linear correlations (R(2)=0.94-0.99) between IgG concentration and read-out when using purified IgG instead of serum. Therefore, we highly recommend standardising pre-analytics and proposing the use of purified IgG for autoantibody immune-profiling with protein microarrays to reduce potential unspecific binding of matrix proteins abundant in serum and plasma samples. Although purified IgG cannot completely compensate the influence of pre-analytics, in highly parallel immune-profiling IgG enables reduction of unspecific effects, which occur when using serum or plasma for analysis on protein microarrays. Reproducibility problems due to pre-analytical processing of blood samples might explain discrepant results reported in various biomarker studies. Copyright © 2015 Elsevier B.V. All rights reserved.

    ABSTRACT: Isolation and characterization of anti HIV-1 broadly neutralizing antibodies (bNAbs) has elucidated new epitopes and sites of viral vulnerability. Anti-HIV-1 bNAbs typically show high levels of somatic mutations in their variable region genes. This feature potentially limits antibody identification, since the mutated antibody sequences are no longer complimentary to primers designed based on germline antibody sequences. Here we report a new set of primers for Igλ light chains that aligns to the 5' end of the leader sequence and is highly efficient for the amplification of antibodies that contain mutations and deletions in the 5' end of human Igλ.

    ABSTRACT: Soluble Glycoprotein VI (GPVI) is an attractive marker for disorders marked by platelet activation, such as thrombotic microangiopathy, myocardial infarction, and stroke. Several groups have already developed an immunoassay for soluble GPVI; however, there are several discrepancies between the groups' assays. In this study, we prepared the two types of recombinant soluble GPVI, the monomeric form GPVI (GPVI-His) and the dimeric form of GPVI (GPVI-Fc), moreover, we generated four anti-GPVI antibodies, F1232-7-1 (7S1), F1232-10-2 (10S2), F1232-19-1 (19D1), and F1232-21-1 (21D1). The former 2 antibodies (7S1 and 10S2) had a high affinity for both GPVI-His and GPVI-Fc, while the latter 2 antibodies (19D1 and 21D1) showed a high affinity for GPVI-Fc but low affinity for GPVI-His. All of the antibodies comparably recognized surface GPVI on resting platelets. Furthermore, we established two immunoassays for soluble GPVI, 7S1/10S2-HRP and 19D1/21D1-HRP (capture antibody/detection antibody). 7S1/10S2-HRP showed equivalent reactivity with GPVI-His and GPVI-Fc, whereas 19D1/21D1-HRP had high affinity for GPVI-Fc but low reactivity with GPVI-His. In terms of reactivity with platelet-derived soluble GPVI, 7S1/10S2-HRP demonstrated sensitive detection whereas 19D1/21D1-HRP was nonreactive. Taken together, 7S1/10S2-HRP is a suitable candidate for a reliable soluble GPVI immunoassay as it has a high affinity for monomeric GPVI.
