Antibodies elicited in a different species from which the antigen originated. These antibodies are directed against a wide variety of interspecies-specific antigens, the best known of which are Forssman, Hanganutziu-Deicher (H-D), and Paul-Bunnell (P-B). Incidence of antibodies to these antigens--i.e., the phenomenon of heterophile antibody response--is useful in the serodiagnosis, pathogenesis, and prognosis of infection and latent infectious states as well as in cancer classification.

When is a heterophile antibody not a heterophile antibody? When it is an antibody against a specific immunogen. (1/250)

Heterophile antibodies are antibodies produced against poorly defined antigens. These are generally weak antibodies with multispecific activities. Human anti-animal antibodies that develop as a result of treatments with animal immunoglobulins are antibodies with strong avidities, produced against well-defined antigens. Although heterophile antibodies and human anti-animal antibodies interfere with immunological assays by similar mechanisms, modes for identifying the sources of the antibodies and for circumventing or retarding the interference may differ. Unfortunately, there has not been a well-organized attempt to encourage correct definition of these antibodies. This problem of inexact definition is highlighted by recent articles in this Journal. In the present discussion, we examine the history leading to this problem and discuss the origins and the reasons that the nature of the antibody is important for rectifying the problem. We propose a simple nomenclature for general usage that should appropriately characterize these antibodies in most cases.  (+info)

Heterotypic protection and induction of a broad heterotypic neutralization response by rotavirus-like particles. (2/250)

The recognition that rotaviruses are the major cause of life-threatening diarrheal disease and significant morbidity in young children has focused efforts on disease prevention and control of these viruses. Although the correlates of protection in children remain unclear, some studies indicate that serotype-specific antibody is important. Based on this premise, current live attenuated reassortant rotavirus vaccines include the four predominant serotypes of virus. We are evaluating subunit rotavirus vaccines, 2/6/7-VLPs and 2/4/6/7-VLPs, that contain only a single VP7 of serotype G1 or G3. In mice immunized parenterally twice, G3 virus-like particles (VLPs) induced a homotypic, whereas G1 VLPs induced a homotypic and heterotypic (G3) serum neutralizing immune response. Administration of three doses of G1 or G3 VLPs induced serum antibodies that neutralized five of seven different serotype test viruses. The inclusion of VP4 in the VLPs was not essential for the induction of heterotypic neutralizing antibody in mice. To confirm these results in another species, rabbits were immunized parenterally with two doses of 2/4/6/7-VLPs containing a G3 or G1 VP7, sequentially with G3 VLPs followed by G1 (G3/G1) VLPs, or with live or psoralen-inactivated SA11. High-titer homotypic serum neutralizing antibody was induced in all rabbits, and low-level heterotypic neutralizing antibody was induced in a subset of rabbits. The rabbits immunized with the G1 or G3/G1 VLPs in QS-21 were challenged orally with live G3 ALA rotavirus. Protection levels were similar in rabbits immunized with homotypic G3 2/4/6/7-VLPs, heterotypic G1 2/4/6/7-VLPs, or G3/G1 2/4/6/7-VLPs. Therefore, G1 2/4/6/7-VLPs can induce protective immunity against a live heterotypic rotavirus challenge in an adjuvant with potential use in humans. Following challenge, broad serum heterotypic neutralizing antibody responses were detected in rabbits parenterally immunized with G1, G3/G1, or G3 VLPs but not with SA11. Immunization with VLPs may provide sufficient priming of the immune system to induce protective anamnestic heterotypic neutralizing antibody responses upon subsequent rotavirus infection. Therefore, a limited number of serotypes of VLPs may be sufficient to provide a broadly protective subunit vaccine.  (+info)

Enhancement of haemolysis by Newcastle disease virus (NDV) after pre-treatment with heterophile antibody and complement. (3/250)

Pre-treatment of Newcastle disease virus (NDV) with fresh human plasma enhances its haemolytic (HL) capacity by several factors. The effect is due to complement activation by the heterophile anti-chick antibody present in human plasma. All the adult human plasmas tested were effective, also 91/100 human cord blood sera. The antibody was mainly of the IgM class. The enhanced HL was due to integration and transference of the complement 'holed' virus envelope membrane and subsequent leakage of haemoglobin. High concentration of activated complement destroys the integrity of the virus enevelope. Treatment of chick erythrocytes and fibroblasts with human plasma also produced lysis of the cells.  (+info)

Heterophile antibodies to bovine and caprine proteins causing false-positive human immunodeficiency virus type 1 and other enzyme-linked immunosorbent assay results. (4/250)

Heterophile antibodies are a well-recognized cause of erroneous results in immunoassays.

Heterophile antibodies segregate in families and are associated with protection from type 1 diabetes. (5/250)

Markedly elevated levels of serum IL-4 were reported previously in 50% of a small group of type 1 diabetes nonprogessors. To determine the patterns of expression for this phenotype, a larger cohort of 58 families containing type 1 diabetic patients was examined. Analysis of the two-site ELISA assay used to measure serum IL-4 revealed evidence for heterophile antibodies, i.e., nonanalyte substances in serum capable of binding antibodies mutivalently and providing erroneous analyte (e.g., IL-4) quantification. Interestingly, relatives without type 1 diabetes were significantly more likely to have this phenotype than were patients with the disease (P = 0.003). In addition, the trait appears to have clustered within certain families and was associated with the protective MHC allele DQB1*0602 (P = 0.008). These results suggest that heterophile antibodies represent an in vivo trait associated with self-tolerance and nonprogression to diabetes.  (+info)

An immunoadhesin incorporating the molecule OX-2 is a potent immunosuppressant that prolongs allo- and xenograft survival. (6/250)

We have established that, in mice receiving donor-specific immunization by the portal vein, the increased graft survival seen is associated with the increased expression of a molecule (OX-2) on a subpopulation of dendritic cells (DC), and polarization of cytokine production to type 2 cytokines on Ag-specific restimulation of cells from these mice. Furthermore, infusion of a mAb to OX-2 blocks both the increased graft survival and the altered cytokine production seen. We have constructed an immunoadhesin in which the extracellular domain of OX-2 is linked to the murine IgG2a Fc region, and we have expressed this molecule (OX-2:Fc) in a eukaryotic (baculovirus) expression system. Incubation of lymphocytes with 50 ng/ml OX-2:Fc inhibits a primary mixed lymphocyte reaction in vitro, as assayed by proliferation and induction of cytotoxic T cells, and also alters cytokine production with decreased IL-2 (IFN-gamma) production and increased IL-4 (IL-10) production. Similarly, in vivo infusion of OX-2:Fc promotes increased allo- and xenograft (both skin and renal grafts) survival and decreases the Ab response to sheep erythrocytes. Our data suggest this molecule might have clinical importance in allo- and xenotransplantation.  (+info)

Accelerated development and aging of the immune system in p53-deficient mice. (7/250)

Development and aging of the immune system lead to an accumulation of memory T cells over the long term. The predominance of T cells of the memory phenotype in the T cell population induces an age-related decline in protective immune responses. We found that development and aging of the immune system were accelerated in p53-deficient (p53-/-) mice; the accumulation of memory T cells was spontaneously accelerated, and a strong T cell-dependent Ab response and Th2 cytokine expression (IL-4, IL-6, and IL-10) were induced by Ag stimulation in young p53-/- mice in the developmental stage. The high T cell proliferative response in the young mice rapidly progressed to a depressed proliferative response in adult mice. It was suggested that the loss of regulation of the cell cycle, DNA repair, and apoptosis by p53 deficiency potentially leads to immunosenescence with the accumulation of memory T cells.  (+info)

Accommodated xenografts survive in the presence of anti-donor antibodies and complement that precipitate rejection of naive xenografts. (8/250)

Hamster hearts transplanted into transiently complement-depleted and continuously cyclosporin A (CyA)-immunosuppressed rats survive long-term despite deposition of anti-donor IgM Abs and complement on the graft vascular endothelium. This phenomenon is referred to as "accommodation." The hypothesis tested here is that accommodated xenografts are resistant to IgM Abs and complement that could result in rejection of naive xenografts. After first hamster hearts had been surviving in cobra venom factor (CVF) + CyA-treated rats for 10 days, a time when the anti-donor IgM Ab level was maximal and complement activity had returned to approximately 50% of pretreatment levels, naive hamster hearts or hamster hearts that had been accommodating in another rat for 14 days were transplanted into those rats carrying the surviving first graft. The naive hearts were all hyperacutely rejected. In contrast, a majority of regrafted accommodating hearts survived long-term. There was widespread Ab and activated complement deposition on the vascular endothelium of accommodating first hearts, second accommodating hearts, and rejected second naive hearts. However, only the rejected naive hearts showed extensive endothelial cell damage, myocardial necrosis, fibrin deposition, and other signs of inflammation. Accommodating first and second hearts but not rejected second naive hearts expressed high levels of the protective genes A20, heme oxygenase-1 (HO-1), bcl-2, and bcl-xL. These data demonstrate that accommodated xenografts become resistant to effects of anti-donor IgM Abs and complement that normally mediate rejection of xenografts. We hypothesize that this resistance involves expression by accommodated xenografts of protective genes.  (+info)

Looking for heterophile antibody test? Find out information about heterophile antibody test. heterophile agglutination test Explanation of heterophile antibody test
The sheep cell agglutination test or heterophile antibody reaction, as it is also called, is a laboratory procedure of considerable value in clinical medicine. In this country one frequently speaks alternately of the Paul-Bunnell test; and in Europe it is often referred to as the Hanganutziu-Deicher reaction. In 1911 Forssman1 recognized the nonspecificity of certain antigen-antibody reactions. The terms heterogenetic, heterophilic, or heterophile are applied to those antibodies that react with an antigen (sheep erythrocytes) which seemingly had nothing to do with their development. One type of heterophile antibody is known as the Forssman antibody, but there are other varieties ...
article{f8408d0b-1483-466c-a428-b904b9c30791, abstract = {,p,Objectives: Heterophilic antibodies, such as rheumatoid factor (RF), are known to interfere with enzyme-linked immunosorbent assays (ELISAs). Treatment of rheumatoid arthritis (RA) with tumour necrosis factor (TNF)-α blockers is well established. The aims of this study were to develop a protocol for blocking the interaction of present heterophilic antibodies and to validate this procedure by evaluating the effect on correlations of cytokine levels to clinical response in RA patients treated with adalimumab. Method: Fourteen patients with active RA were evaluated at baseline and 3 months after starting adalimumab treatment. Cytokines were analysed with a commercial 12-plex bead ELISA. To block interference by RF, a commercial blocker (HeteroBlock) was used. To determine the optimal concentration of HeteroBlock, patient sera were analysed with different concentrations of HeteroBlock. Subsequently, baseline and follow-up sera from the 14 ...

Heterophile definition is - of, relating to, or being an antibody circulating in blood serum that is reactive with antigen originating in a different species. How to use heterophile in a sentence.
Interference from heterophilic antibodies. Heterophilic antibodies are found in human patient serum and plasma. They are poly-reactive antibodies recognising IgG from different animal species. These antibodies are non-specific, have no defined antigen and can bind to the Fc region of the assay antibody causing a false positive test signal. Heterophilic antibodies found in patient serum react with mouse (HAMA) and rat IgG. Since conventional specific and high affinity monoclonal antibodies can only be obtained from the mouse and rat, heterophilic antibodies can be a limitation in diagnostic tests. Chimeric monoclonal antibodies (in particular human chimeric antibodies) are a solution to this problem.. ...
In most cases of infectious mononucleosis, the clinical diagnosis can be made from the characteristic triad of fever, pharyngitis, and lymphadenopathy lasting for 1 to 4 weeks. Serologic test results include a normal to moderately elevated white blood cell count, an increased total number of lymphocytes, greater than 10% atypical lymphocytes, and a positive reaction to a mono spot test. In patients with symptoms compatible with infectious mononucleosis, a positive Paul-Bunnell heterophile antibody test result is diagnostic, and no further testing is necessary. Moderate-to-high levels of heterophile antibodies are seen during the first month of illness and decrease rapidly after week 4. False-positive results may be found in a small number of patients, and false-negative results may be obtained in 10% to 15% of patients, primarily in children younger than 10 years of age. True outbreaks of infectious mononucleosis are extremely rare. A substantial number of pseudo-outbreaks have been linked to ...

Heterophile antibodies, in patients with infectious mononucleosis, may be present as early as the fourth day of illness, and by the twenty-first day of illness, 90% of patients will exhibit a positive test. The Epstein-Barr virus causes infectious mononucleosis.
The virus is spread by intimate oral contact among adolescents, but how preadolescents acquire the virus is not known. During the incubation period of approximately 6 weeks, viral replication first occurs in the oropharynx followed by viremia as early as 2 weeks before onset of illness. The acute illness is marked by high viral loads in both the oral cavity and blood accompanied by the production of immunoglobulin M antibodies against EBV viral capsid antigen and an extraordinary expansion of CD8+ T lymphocytes directed against EBV-infected B cells. ,diet plan,healthy eating,healthy food,pregnancy tips,glucose tolerance test,diabetes test.

Human anti-mouse antibody (HAMA) is an antibody found in humans which reacts to immunoglobins found in mice. Antibody treatment is a type of therapy that is used to treat certain types of cancer and immune disorders. Antibodies are proteins which are naturally formed by the body in response to a foreign substance, known as an antigen. Antibodies can also be grown outside of the patients body and injected into them to help aid the immune system to fight disease. These types of antibodies are typically called monoclonal antibodies because they are created to target one specific antigen. Herceptin and Avastin, two widely used cancer fighting drugs, are examples of monoclonal antibodies. For several decades, and until recently, mice were used extensively in the production of monoclonal antibodies (MAbs). But the treatments were not as effective as doctors had hoped. One problem was that patients reacted to the mouse antibodies as if they were a foreign substance, and created a new set of antibodies ...
TSH or free T4 levels may be diagnostically misleading in cases of abnormalities in hypothalamus or pituitary function, in which the usual negative feedback is not seen and TSH may remain within normal limits.. Misinterpretation due to the inclusion of biologically inactive TSH isoforms in TSH assays can lead to a missed diagnosis of central hypothyroidism. TSH assays include biologically inactive TSH isoforms, which are secreted when the pituitary is damaged or when hypothalamic TRH stimulation is deficient.. Most thyroid testing is performed by either immunoassay, in which labeled and unlabeled ligands compete for a limited number of antibody sites, or immunometric assays, in which an antibody is bound to a solid surface rather than an antibody. Cross reactivity of auto-antibodies or heterophilic antibodies can affect diagnostic accuracy of competitive binding-based tests.. The term heterophilic antibodies is often loosely applied to relatively weak antibodies with multiple activity sites, ...

Interpretation of hormone levels in older patients: points for consideration. (Sztefko and Szybowska 2012) Download. Blood hormone and tumor marker concentrations are usually determined by immunochemical methods which are based on an unique reaction between antigen and assay capture antibody. Despite the speed and simplicity of assays performance on automatic immunochemistry platforms, the interpretation of final results requires a deep knowledge of method fallibility. General lack of immunoassays standardization, presence of cross-reacting substances in patients sample, limitation of free hormones measurement due to abnormal analyte binding protein concentrations, assay interferences due to patients autoantibodies, and heterophilic antibodies, as well as proper interpretation of very low- and very high-sample analyte levels, are the main points discussed in respect to hormones and tumor markers measurement in geriatric population..

The symptoms and signs of infectious mononucleosis are variable and imitative of many common diseases. The diagnosis is made by the laboratory findings of a lymphocytosis with atypical cells and of an increased titer of the heterophile antibody (Paul-Bunnell test). Often these tests should be repeated, for a single negative result does not rule out the presence of the disease. Infectious mononucleosis should be suspected in every case of sore throat and in every acute illness with lymph node enlargement and/or splenomegaly, but unfortunately no single physical sign is so characteristic that its finding invites the repetition of the diagnostic ...

They are initially expressed in germline configuration and are encoded by a small number of structurally-related germline progenitors. The transplantation of genetically-modified pig organs prevents hyperacute rejection, but delayed graft rejection still occurs, partly due to humoral responses. IgVH genes encoding induced xenoantibodies are predominantly, not exclusively, derived from germline progenitors in the VH3 family. We have previously identified the immunoglobulin heavy chain ...

article{3233604, abstract = {{Background: Previous studies showed that radiolabeled murine monoclonal antibody (mAb) 14C5 and its Fab and F(ab)2 fragments, targeting αvβ5 integrin, have promising properties for diagnostic and therapeutic applications in cancer. To diminish the risk of generating a human anti-mouse antibody response in patients, chimeric variants were created. The purpose of this study was to recombinantly produce chimeric antibody (chAb) derivatives of the murine mAb 14C5 and to evaluate the in vitro and in vivo characteristics. Methods: In vitro stability, specificity, and affinity of radioiodinated chAb and fragments (Iodo-Gen method) were examined on high-expressing αvβ5 A549 lung tumor cells. In vivo biodistribution and pharmacokinetic characteristics were studied in A549 lung tumor-bearing Swiss Nu/Nu mice. Results: Saturation binding experiments revealed high in vitro affinity of radioiodinated chAb, F(ab)2, and Fab, with dissociation constants (KD) of 1.19 ± 0.19, ...

Human Anti-Mouse Antibodies (HAMA) may be present in samples from patients who have received immunotherapy utilizing monoclonal antibodies. Additionally, other heterophile antibodies such as human anti-goat antibodies may be present in patient samples. Manufacturers formulate assays to minimize the effects of these antibodies; however careful evaluation of patient results must be done when patients are known to have such antibodies. These specimens should not be assayed with this Digoxin procedure.. Digoxin-Like Immunoreactive Factors (DLIF) or Digoxin-Like Immunoreactive Substances (DLIS) have been identified in blood from patients in renal failure, liver failure, newborns and pregnant women in the third trimester. Studies have established that the presence of DLIF or DLIS in a sample can result in a false elevation of Digoxin by this method.. Specimens from patients undergoing Digoxin Immune FAB (i.e. Digibind) treatment should not be assayed with this Digoxin procedure until 48 hours after ...
Infectious Mononucleosis in Adolescents What is infectious mononucleosis? Infectious mononucleosis, also known as mononucleosis, mono, or glandular fever, is characterized by swollen lymph glands and chronic fatigue. What causes infectious mononucleosis? Infectious mononucleosis is either caused by the Epstein-Barr virus (EBV) or the cytomegalovirus, both of which are members of the herpes simplex virus family. Consider the following statistics: In the US, almost 95 percent of adults between 35 and 40...

N2 - During a 50-month period the diagnosis of heterophil antibody negative infectious mononucleosis or of a mononucleosis-like illness was made in 43 patients with a variable clinical picture and significant numbers of atypical lymphocytes. Epstein-Barr virus (EBV)-related serologic tests revealed that seven patients had primary EBV infections based on the detection of immunoglobulin M (IgM) antibodies to EB-viral capsid antigens (IgM-VCA) and the absence of anti-Epstein-Barr virus associated nuclear antigen (EBNA) on most initial specimens (six of seven cases). Thirty cases were due to active cytomegalovirus (CMV) infections and both detectable ...
Severity of disease is markedly increased when infection with dengue virus type 2 (DENV-2) follows infection with DENV-1. Studies have shown that heterologous neutralizing antibody titers are inversely correlated with severity of a second infection. If this mechanism controlled disease severity in Cuba, heterotypic antibody titers should have declined over time. To determine whether phenotypic changes in dengue antibodies occur over time, we analyzed serum samples collected 4-8 and 20-22 years after DENV-1 infection. We found a significant increase in mean titer of homologous DENV-1 neutralizing antibodies and a significant decrease in heterologous antibodies to 1 of 2 genotypes of DENV-2 virus (the American genotype). Asian DENV-2 viruses were not neutralized during either interval; however, the American genotype underwent phenotypic changes in heterotypic viral neutralizing antibodies in the predicted direction. This finding may be related to the time-dependent changes in severity of disease found

Two-site immunometric assays for multideterminant antigens are described in which the antigen is reacted with an immobilized monoclonal antibody directed against one antigen determinant and a second monoclonal antibody that is directed against a distinct antigenic determinant and is of a different class or subclass than the immobilized monoclonal antibody. The second monoclonal antibody is labeled in direct versions of the assay and is reacted with a labeled antibody against it in indirect versions of the assay. The immobilizing medium and classes (subclasses) of the antibodies may be selected so as to reduce the likelihood of nonspecific binding enhance sensitivity and/or permit signal amplification.

Once a person has had mononucleosis, the virus remains dormant for the rest of that persons life. Once a person has been exposed to the Epstein-Barr virus, a person is usually not at risk for developing mononucleosis again..

Mononucleosis may also result from other viruses besides the Epstein-Barr. Typically, mono is not a very serious condition, and people who have had mono may not be infected again for the rest of their life since they develop immunity against the infection.
Many parents think of mononucleosis as a disease of teens and young adults. They dont know that young children are also commonly affected.
Mononucleosis - or mono - is an infection that produces flu-like symptoms, and usually goes away on its own in a few weeks with the help of plenty of fluids and rest.
