In an assay for a target nucleotide sequence employing hybridization with a target probe nucleotide sequence, cross reaction between the target probe and a non-target nucleotide sequence, capable of hybridizing with the target probe, is prevented or diminished by introducing, at some point during the hybridization, a non-target probe which hybridizes preferentially with the non-target nucleotide sequence. The melting temperature for the non-target probe/non-target nucleotide sequence hybrid is preferably greater than that of the target probe/non-target sequence hybrid. The hybridization can be carried out under isothermal conditions or preferentially with gradual cooling.

Heterosubtypic immunity, defined as cross-reactive immune responses to influenza virus of a different serotype than the virus initially encountered, was investigated in association with virus-specific cytotoxic T lymphocyte (CTL) responses induced in systemic and mucosa-associated lymph nodes after immunization via different routes. Mice immunized by the pulmonary route with live nonpathogenic influenza virus, strain Udorn (H3N2), survived challenge with mouse-adapted pathogenic influenza virus, strain PR/8/34 (H1N1). These mice developed strong heterosubtypic CTL responses in spleen, cervical lymph nodes (CLN), and mediastinal lymph nodes (MLN). Alternately, only 20% of mice immunized intravenously, intraperitoneally, or intranasally survived the challenge; all of these developed CTL responses in spleen and CLN, but not in MLN. Direct correlation between short-term and long-term memory heterosubtypic CTL responses induced in MLN and host recovery after lethal infection indicates that these CTL

Why do T-cells behave like prostitutes? #MSBlog #MSResearch #ResearchSpeak. As you know I think EBV causes MS, i.e. I think it is the pivotal factor in the causal pathway that leads to the onset of the disease. Studies have consistently shown that the immune response to EBNA-1 (EBV associated nuclear antigen-1) is increased in people at risk of MS and/or who have MS. Please note the use of and/or, because most people develop biological disease, i.e. MS, before their first symptoms. EBNA-1 is a so called latency programme antigen and keeps the EBV genome in hibernation. Some feel EBNA-1 is a molecular mimic and triggers cross-reactive immune responses to self-proteins. This is one of the main EBV hypotheses. Another hypothesis is that EBV infects cells within the brain and spinal cord and hence stimulates immune responses, by up-regulating innate immune mechanisms, or danger signals. If EBV does infect the central nervous system you would expect the nervous system to be enriched for T-cells ...
To assess herd immunity to swine influenza viruses, we determined antibodies in 28 paired serum samples from participants in a prospective serologic cohort study in Hong Kong who had seroconverted to pandemic (H1N1) 2009 virus. Results indicated that infection with pandemic (H1N1) 2009 broadens cross-reactive immunity to other recent subtype H1 swine viruses ...

AbstractIdentification of protective T cell responses against SARS-CoV-2 requires distinguishing people infected with SARS-CoV-2 from those with cross-reactive immunity to other coronaviruses. Here we show a range of T cell assays that differentially capture immune function to characterise SARS-CoV-2 responses. Strong ex vivo ELISpot and proliferation responses to multiple antigens (including M, NP and ORF3) are found in 168 PCR-confirmed SARS-CoV-2 infected volunteers, but are rare in 119 uninfected volunteers. Highly exposed seronegative healthcare workers with recent COVID-19-compatible illness show T cell response patterns characteristic of infection. By contrast, |90% of convalescent or unexposed people show proliferation and cellular lactate responses to spike subunits S1/S2, indicating pre-existing cross-reactive T cell populations. The detection of T cell responses to SARS-CoV-2 is therefore critically dependent on assay and antigen selection. Memory responses to specific non-spike proteins
Heterosubtypic T cell-mediated immunity to influenza A viruses in humans has been widely reported (24-26, 36). While cross-reactive T cells cannot prevent establishment of infection, they can enhance recovery by promoting virus clearance and reduce the severity of illness (15). It has also been demonstrated that in vitro T cell cultures derived from healthy individuals can lyse target cells infected with swine or avian influenza viruses (28, 29). Together with a large number of studies in mice that demonstrated cross-protection conferred by influenza A-specific T cells during subsequent challenges (reviewed in ref. 11), these studies suggest that vaccines stimulating cross-reactive T cell populations, potentially used in conjunction with the current antibody-based strategy, may confer broader and more effective protection against a potential pandemic strain. However, most studies using T cell cultures expanded in vitro were unable to assess accurately the overall influenza-specific memory T cell ...
Control of swine influenza by vaccination has become more difficult in recent decades, as the evolution of the virus has resulted in inconsistent responses to traditional vaccines. Standard commercial swine flu vaccines are effective in controlling the infection when the virus strains match enough to have significant cross-protection, and custom (autogenous) vaccines made from the specific viruses isolated are created and used in the more difficult cases.[80][81] Present vaccination strategies for SIV control and prevention in swine farms typically include the use of one of several bivalent SIV vaccines commercially available in the United States. Of the 97 recent H3N2 isolates examined, only 41 isolates had strong serologic cross-reactions with antiserum to three commercial SIV vaccines. Since the protective ability of influenza vaccines depends primarily on the closeness of the match between the vaccine virus and the epidemic virus, the presence of nonreactive H3N2 SIV variants suggests that ...
Self-reactive CD4 T cells are thought to have a central role in the pathogenesis of many chronic inflammatory human diseases. Microbial peptides can activate self-reactive T cells, but the structural basis for such crossreactivity is not well understood. The Hy.1B11 T cell receptor (TCR) originates from a patient with multiple sclerosis and recognizes the self-antigen myelin basic protein. Here we report the structural mechanism of TCR crossreactivity with two distinct peptides from human pathogens. The structures show that a single TCR residue (CDR3α F95) makes the majority of contacts with the self-peptide and both microbial peptides (66.7-80.6%) due to a highly tilted TCR-binding topology on the peptide-MHC surface. Further, a neighbouring residue located on the same TCR loop (CDR3α E98) forms an energetically critical interaction with the MHC molecule. These data show how binding by a self-reactive TCR favors crossreactivity between self and microbial antigens.

Transglutaminase 2 (TG2) is a ubiquitously expressed enzyme that catalyzes the posttranslational modification of glutamine residues on protein or peptide substrates. 3-bromo-4 5 (DHI) scaffold have been widely used to study TG2 biology and are well tolerated in vivo but these compounds have only modest potency and their selectivity toward other transglutaminase homologues is largely unknown. In the present work we first profiled the selectivity of existing inhibitors against the most pertinent TG isoforms (TG1 TG3 and FXIIIa). Significant cross-reactivity of these small molecules with TG1 was observed. Structure-activity and ?selectivity analyses led to the identification of modifications that improved potency and isoform selectivity. Preliminary pharmacokinetic analysis of the most promising analogues was also undertaken. Our new data provides a clear basis for the rational selection of dihydroisoxazole inhibitors as tools for in vivo biological investigation. Kitl Introduction The mammalian ...
TY - JOUR. T1 - Epidemics in Competition. T2 - Partial Cross-Immunity. AU - Andreasen, Viggo. PY - 2018. Y1 - 2018. N2 - The competition between two pathogen strains during the course of an epidemic represents a fundamental step in the early evolution of emerging diseases as well as in the antigenic drift process of influenza. The outcome of the competition, however, depends not only on the epidemic properties of the two strains but also on the timing and size of the introduction, characteristics that are poorly captured by deterministic mean-field epidemic models. We describe those aspects of the competition that can be determined from the mean-field models giving the range of possible final sizes of susceptible hosts and cumulated attack rates that could be observed after an epidemic with two cross-reacting strains. In the limit where the size of the initial infection goes to zero, the possible outcomes lie on a (one dimensional) curve in the outcome space.. AB - The competition between two ...

A gray area at times. Have used the Scytek kit (check out website) for frozen sections, but did not use their peroxidase blocker, it ate frozens off the slide. Substituted a Dako peroxidase blocker for frozens was much friendlier. The kicker with this kit, their special blocker is excellent, and you have to use their chromogen with this kit. What really worked for us was to use their two blockers (not the peroxidase block though),a biotinylated primary in place of a secondary antibody with the Scytek kit since we did not have a purified primary on hand. We also diluted out the biotinylated primary further, so do a more extended dilution panel, this reduced our cross reaction background. This is the basis of the DAKO ARK kit, biotinylating the primary, some antibodies don biotinylate as well, a potential problem, but may work with yours, so another option - DAKO ARK kit. There are others on the market, Zymed, Innovex, Vector MOM kit, etc, all worth a try. Have heard some mixed reviews on Mouse ...

Hello, I work with fish in a resarch lab and with some of the antibodies I use I get what I would consider non-specific crossreactivity with mucus either covering the body surface or in mucocyte granules. More often this problem would arise with rabbit polyclonal anti-peptide antibodies using neat serum. I usually get around this by affinity purifying using the peptide but in some cases this is not possible. Someone once told me that mucoproteins have a large number of antigenic determinants increasing the likelyhood of crossreactivity but I could never find a reference. Ive searched through the archives but couldnt find an explanation except for a suggestion that it might be charge related. Could someone please shed some light on this situation for me. It is something that has bugged me for the longest time. Thank you for any insight. Sincerely, Jon _______________________________________________ Histonet mailing list [email protected] ...

In this thesis the role of bacteria for the induction of autoimmunity was investigated. In detail, it was examined whether bacteria are able to activate autoreactive CD4+-T-cells antigen-specific (cross-reactivity) or antigen-unspecific (bystander-activation). It was shown that the examined transgenic MBP-peptide specific T-cell-receptor recognized many natural occurring cross-reactive peptides of microbial origin, which induced an activation of the T-cells in vitro and which could induce autoimmune encephalomyelitis (EAE) in the T-cell-receptor transgenic mice in vivo. Furthermore, it was examined, whether lipopolysaccharide (LPS) as activator of the innate immune system could induce an unspecific activation of the autoreactive T-cells in vitro and whether administration of LPS in the transgenic mice could induce EAE in vivo. It was shown that LPS activates a small percentage of CD4+ - T-cells. Application of LPS to the transgenic T+alpha- mice induced EAE. Therefore, the role of ...

The properties of high affinity and specificity of antibodies are successfully employed in assays used for quantification of specific analytes in complex mixtures. The method is indirect in the sense that it is the antibody-analyte complex that is detected rather than the analyte per se. However, if the quality of the antibody is good, i.e., low cross reactivity with other molecules, there is a strong relationship between the measured signal from the complex and the concentration of the analyte. This relationship can be determined by the use of calibrators with known concentrations, which allow for a standard curve to be constructed and the concentration in a sample to be calculated.. ...

TY - JOUR. T1 - Generation of recombinant rotavirus with an antigenic mosaic of cross-reactive neutralization epitopes on VP4. AU - Komoto, Satoshi. AU - Kugita, Masanori. AU - Sasaki, Jun. AU - Taniguchi, Koki. PY - 2008/7. Y1 - 2008/7. N2 - Recombinant rotavirus (RV) with cDNA-derived chimeric VP4 was generated using recently developed reverse genetics for RV. The rescued virus, KU//rVP4(SA11)-II(DS-1), contains SA11 (simian RV strain, G3P[2])-based VP4, in which a cross-reactive neutralization epitope (amino acids 381 to 401) on VP5* is replaced by the corresponding sequence of a different P-type DS-1 (human RV strain, G2P[4]). Serological analyses with a panel of anti-VP4- and -VP7-neutralizing monoclonal antibodies revealed that the rescued virus carries a novel antigenic mosaic of cross-reactive neutralization epitopes on its VP4 surface. This is the first report of the generation of a recombinant RV with artificial amino acid substitutions.. AB - Recombinant rotavirus (RV) with ...
At the American Association for the Advancement of Science meeting in Boston last weekend, Emory Vaccine Center researcher Mark Mulligan presented some limited findings on immune responses in Zika-infected humans, who were returned US travelers or expatriates.. The results were intriguing, despite the small number of study participants: five, two of whom were pregnant. Detailed information has not been available about immune responses against Zika in humans, especially T cell responses.. Highlights from Mulligans abstract:. *All five seemed to have a hole in their immune systems - functional antiviral killer CD8 T cells were rare, despite activation of CD8 T cells in general and strong responses from other cell types.. *Cross-reactive immune responses, based on previous exposure to dengue and/or yellow fever vaccine, may have blunted Zikas peak.. *Even with prolonged maternal viremia, both pregnancies resulted in live births of apparently healthy babies.Zika infection during pregnancy can ...

Antigen cross-reactivity is an inbuilt feature of the T cell compartment. However, little is known about the flexibility of T cell recognition in the context of genetically variable pathogens such as HIV-1. In this study, we used a combinatorial library containing 24 billion octamer peptides to characterize the cross-reactivity profiles of CD8+ T cells specific for the immunodominant HIV-1 subtype B Nef epitope VY8 (VPLRPMTY) presented by HLA-B*35∶01. In conjunction, we examined naturally occurring antigenic variations within the VY8 epitope. Sequence analysis of plasma viral RNA isolated from 336 HIV-1-infected individuals revealed variability at position (P) 3 and P8 of VY8; Phe at P8, but not Val at P3, was identified as an HLA-B*35∶01-associated polymorphism. VY8-specific T cells generated from several different HIV-1-infected patients showed unique and clonotype-dependent cross-reactivity footprints. Nonetheless, all T cells recognized both the index Leu and mutant Val at P3 equally ...

In a subset of patients with limited cutaneous (lc) systemic sclerosis (SSc), anti-CENP-A antibodies (Ab) cross-react with a peptide (FOXE3p53-62) that presents striking homology with one of the two immunodominant epitopes of CENP-A (Ap17-30). We searched for clinical correlates of anti-FOXE3p53-62 Ab by measuring their levels along with those of Ab to Ap17-30 and to the second immunodominant epitope of CENP-A, namely Ap1-17. Serum samples were obtained from 121 patients with SSc, 46 patients with systemic lupus erythematosus (SLE) and 25 healthy blood donors (HBD). The reactivity of serum IgG to Ap1-17, Ap17-30 and FOXE3p53-62 was measured by ELISA. The corresponding anti-peptide Ab were affinity-purified from pooled SSc sera and used to establish standard curves for quantifying these Ab in patients and HBD. Receiver operating characteristics (ROC) analysis, comparing SSc patients who were positive for anti-CENP Ab (ACA+) to those who were negative, was used to find cut-off points for dichotomizing the

Swine flu has been in the headlines for days now. The headlines change every day. By the time this article is printed, the situation will have changed even more. Therefore, it is hard to write a timely article on this particular disease. There are some facts that bear no relation to time. The first is that we have flu epidemics every year. They usually occur in the December to February time frame. We start an immunization program for it prior to that. The viruses contained in the immunization are scientists best guesses as to which flu viruses are going to be prevalent that particular year. They usually guess correctly so many people are protected before each years outbreak. One of the issues with swine flu is that there is currently no immunization for it. Cross reaction to other flu strains is not present. Therefore, no one is immune to the virus. For that reason many more people would be affected by an outbreak. The second fact is that every year people who get the flu die from its ...
Centralized (ancestral and consensus) HIV-1 envelope immunogens induce broadly cross-reactive T cell responses in laboratory animals; however, their potential to elicit cross-reactive neutralizing antibodies has not been fully explored. Here, we report the construction of a panel of consensus subtype B (ConB) envelopes and compare their biologic, antigenic, and immunogenic properties to those of two wild-type Env controls from individuals with early and acute HIV-1 infection. Glycoprotein expressed from full-length (gp160), uncleaved (gp160-UNC), truncated (gp145), and N-linked glycosylation site deleted (gp160-201N/S) versions of the ConB env gene were packaged into virions and, except for the fusion defective gp160-UNC, mediated infection via the CCR5 co-receptor. Pseudovirions containing ConB Envs were sensitive to neutralization by patient plasma and monoclonal antibodies, indicating the preservation of neutralizing epitopes found in contemporary subtype B viruses. When used as DNA vaccines ...

A new paper has just appeared in PLoS Medicine on an old topic: whether seasonal influenza vaccines might also cause enough cross-reactivity to protect against H5N1. The basic idea is simple. The immune system sees the surface proteins on the flu virus and makes protective antibodies against them. The major stimulant for this is the hemagglutinin protein (HA), the H part of H5N1. There are 16 different immunological flavors of HA that cross-react very little.
Hi, I have a mouse anti-bovine glutamate dehydrogenase mAb and Im curious whether anyone would know whether it will crossreact with Human GDH. I think the two proteins are fairly similiar but how similiar are humans with cows??? Please send a reply to my E-mail dsho at med.unc.edu Thanx for any thoughts. Moo Moo, Dave Shock ...

We would like to thank Dr. Sylvain Lesne for his interest in our work and for his comments. We would like to clarify some of the points he raised concerning our report, since we disagree with some of his statements.. Regarding Aβ detection, we used the 6E10 antibody to monitor the level of APP transgene expression at the age we performed our analysis of spine density in vivo (i.e., three months postnatal), but our intention was not to characterize the presence of Aβ1-42 oligomers at this age in this mouse strain. They have been extensively characterized previously by others (see below). The 6E10 antibody is known to recognize human APP, CTF-β, and Aβ. We acknowledge that the band running below 15 kDa should be considered as a mixture of CTF/Aβ since tissues were homogenized in RIPA buffer. Regarding the APP signal at ~100 kDa, we could clearly detect a faint signal in the wild-type mice (after overexposure of the membrane), suggesting that the antibody can cross-react with mouse APP. This ...

Anne Schuchat: I think one possibility is that older people might have been exposed to H1N1 strains a long time ago that might have some relation to the strain were seeing now. Our virologists have compared it to all these other strains and this is really different. This is not a close, genetic relative of any of the H1N1s that have been a problem in people, but the immunologic characteristics might be different than the genetic characteristics and so it would be very great if older people had been exposed to some H1N1 a long time ago that had some relationship with this one immunologically and that might lead to that pre-existing immune they we hope is there, but were not sure is there. So we dont have a particular virus that were thinking about because the genetic characteristics are so different, but we are wondering about whether there were some viruses around back in the 30s, 40s or 50s that might be immunologically similar to the one were seeing now ...
Preamble: Stanford points out that the average 70-year-old is on 7 (seven) pharmaceutical agents1. Since literally hundreds of potential adverse reactions can occur with each medication, imagine the potential for cross reactivity (same reference quotes an average number of potential side effects per drug to be 69)…especially if a drugs metabolite can impart adverse reactions too?
