TY - JOUR. T1 - Specific IgG Subclass Antibody Levels and Phagocytosis of Serotype 14 Pneumococcus Following Immunization. AU - KANIUK, A. St C.. AU - LORTAN, J. E.. AU - MONTEIL, M. A.. PY - 1992/12. Y1 - 1992/12. N2 - Complement and specific antibody directed against capsular polysaccharide are necessary for efficient phagocytosis of pneumococci. In normal adults, specific antibody to pneumococci is predominantly of the IgG2 subclass. However, the role of IgG2 in bacterial clearance is debatable. We therefore decided to investigate the relationship between specific IgG subclass antibody levels and phagocytosis of serotype 14 pneumococcus, before and after immunization with a pneumococcal capsular polysaccharide vaccine. Specific IgG subclass antibody was measured by an ELISA technique and the effect of serum on phagocytosis of radiolabelled pneumococci by normal polymorphs was determined. We found that in the presence of complement, phagocytosis correlated significantly with both specific IgGl ...
We sought to compare Pneumovax®23 responses in adults with subnormal IgG subclass concentrations. We studied adults with normal total IgG, frequent/severe respiratory infection, and subnormal IgG1, IgG3, or IgG1 + IgG3 before and after Pneumovax®23. We defined response as serotype-specific IgG | 1.3 μg/mL and aggregate response as IgG | 1.3 μg/mL for ≥70% of all serotypes tested. We compared patients with and without serotype-specific responses and performed logistic regression on aggregate responses using: age; male sex; body mass index; autoimmune condition(s); atopy; other allergies; subnormal IgGSc immunophenotypes; IgA; and IgM. There were 59 patients (mean age 44 ± 13 (SD) years; 83.1% women). Median days between pre- and post-Pneumovax®23 testing was 33 (range 19-158). The median post-vaccination summated concentration of serotype-specific IgG was higher in patients with subnormal IgG1 than subnormal IgG3 (responders and non-responders). All subnormal IgG1 + IgG3 non-responders responded
TY - JOUR. T1 - A cohort study of the association between serum immunoglobulin G concentration and preweaning health, growth, and survival in Holstein calves. AU - Pithua, P.. AU - Aly, Sharif S. PY - 2013. Y1 - 2013. N2 - The association between serum IgG concentration and preweaning health performance in Holstein calves were evaluated in a prospective cohort study design framework. Post colostral blood samples were collected from 561 calves and serum IgG concentrations were quantitated using a single radial immunodiffusion assay. Preweaning treatments for diarrhea, pneumonia, omphalitis and frequency of antibiotic therapy plus calf death events were recorded until calves were weaned at approximately 60 d of age. Logistic regression modeling was used to evaluate the association between failure of passive transfer of immunity (FPT, serum IgG , 10g/L) and risk of diarrhea, pneumonia, omphalitis, frequency of antibiotic therapy and death. Calves with FPT were twice as likely to suffer from scours ...
Mycobacterium tuberculosis-specific antibodies (immunoglobulin M [IgM], IgE, IgG, and IgG subclasses) were determined in 164 tuberculosis patients (pulmonary involvement, n = 135; lymph node involvement, n = 29), 59 healthy household contacts (HC), and 51 healthy endemic donors (EC) by a quantitative enzyme-linked immunosorbent assay for reactivity with culture filtrate. Among the isotypes, significant differences between tuberculosis patient groups with either pulmonary or lymph node involvement and healthy control groups (HC and EC) were detected only for IgG (P , 0.001) and IgG1 (P , 0.001) antibodies. Pulmonary patients also showed a significant difference with IgM (P , 0.01) and IgE (P , 0.05) antibodies. HC showed elevation of only IgM antibodies compared with EC, indicating that IgM antibodies may be an indicator of recent infection with M. tuberculosis. These results suggest that the switching of IgM antibody response to IgG1 is a critical event in disease progression. Polyclonal IgG1, ...

X-linked agamaglobulinemia (XLA) or Brutons disease is a genetic disease resulting from a mutation in the Brutons tyrosine kinase (Btk) gene. This mutation leads to B cell arrest during differentiation (1). This disease was first described by Ogden Bruton in 1952 (2). Approximately 85% of the affected subjects are male (3). This disorder is inherited as an X-linked recessive trait. Carrier females have no symptoms but have a 50% chance for transmission of the disorder to each of their sons. It is now possible to determine if the fetus of a carrier mother has XLA (4). The prevalence of the disease ranges from 1 in 10,000 to 1 in 50,000 (1). Half of the affected individuals are diagnosed during the first year of life and more than 90% of them are diagnosed up to fifth year (3). Diagnosis of the disease is suggested by lymphoid hypoplasia (minimal or no tonsillar tissue and no palpable lymph node) and total immunoglobulins level less than 100 mg/dl. Isohemagglutinins and antibodies to antigens given
After albumin, immunoglobulin G (IgG) are the most abundant proteins in human serum, with IgG1 and IgG3 being the most abundant subclasses directed against protein antigens. The quality of the IgG-Fc-glycosylation has important functional consequences, which have been found to be skewed towards low fucosylation in some antigen-specific immune responses. This increases the affinity to IgG1-Fc-receptor (FcγR)IIIa/b and thereby directly affects downstream effector functions and disease severity. To date, antigen-specific IgG-glycosylation have not been analyzed for IgG3. Here, we analyzed 30 pregnant women with anti-K alloantibodies from a prospective screening cohort and compared the type of Fc-tail glycosylation of total serum- and antigen-specific IgG1 and IgG3 using mass spectrometry. Total serum IgG1 and IgG3 Fc-glycoprofiles were highly similar. Fc glycosylation of antigen-specific IgG varied greatly between individuals, but correlated significantly with each other for IgG1 and IgG3, except for
Immunoglobulin G (IgG) that plays central role in adaptive immunity is the most abundant immunoglobulin found in human plasma. All IgG molecules are N-glycosylated.

3.3.2. Properties of Immunoglobulins. General. All immunoglobulins appear to be glycoproteins but the carbohydrate content ranges from 2-3% for IgG to 12-14% for IgM, IgD and IgE. The physicochemical proper-ties of the immunoglobulins are summarized in Table 3.2. Each class possesses a characteristic type of heavy chain. Thus IgG possesses g chains; IgM, m chains; IgA, achains, IgD, dchains and IgE, echains. Variation in heavy chain structure within a class gives rise to immunoglobulin subclasses. For example the human IgG pool consists of four subclasses reflecting four distinct types of g heavy chain. The physicochemical properties of the immunoglobulins vary between the different classes. Note that IgA occurs in a dimeric form {sigA) in association with a protein chain termed the secretory piece. The diversity of structure of the different classes suggests that they perform different functions, in addition to their primary function of antigen binding. In spite of this diver-sity all ...

Collectively, our data indicate that targeting Ags to CD180 induces rapid activation of Ag-specific B cells, leading to significant IgG production within 7 d. Remarkably, a single injection of Ag-αCD180 without any additional adjuvant also led to the development of both Ab affinity maturation and immunological memory (Fig. 3). Furthermore, although severely impaired, Ag-specific IgG production and responses to secondary immunizations were retained in CD40 KO mice (Fig. 3 H), even though CD40 KO mice did not make Ag-specific IgG or develop memory Ab-producing cells in response to Ag in alum, as reported previously (Kawabe et al., 1994). The Ab responses induced required the Ags to be attached to anti-CD180 and could be induced to both haptens and protein Ags.. Why is this mode of immunization so effective in rapidly raising IgG Ab responses? Previous studies showed that i.p. inoculation of high doses of αCD180 could induce increases in plasma cells (500 µg) and polyclonal Ig production (250 ...

Antibody. Computer graphic of a molecule of immunoglobulin G1, a type of antibody protein that the immune system uses to fight infections. Like all proteins, it is comprised of amino acid groups. Immunoglobulin G is the most common antibody found in blood. They are produced by lymphocytes (a type of white blood cell) in response to the proteins (antigens) found on foreign cells such as bacteria and viruses. Each antibody recognises a specific antigen, either destroying or neutralising it. Immunoglobulin G can cross a mothers placenta, making it important in the immune response of a developing foetus. - Stock Image P270/0045

Anti-Rabbit IgG (H&L) Biotin Antibody generated in goat detects reactivity to Rabbit IgG. Secreted as part of the adaptive immune response by plasma B cells, immunoglobulin G constitutes 75% of serum immunoglobulins. Immunoglobulin G binds to viruses, bacteria, as well as fungi and facilitates their destruction or neutralization via agglutination (and thereby immobilizing them), activation of the compliment cascade, and opsinization for phagocytosis. The whole IgG molecule possesses both the F(c) region, recognized by high-affinity Fc receptor proteins, as well as the F(ab) region possessing the epitope-recognition site. Both the Heavy and Light chains of the antibody molecule are present. Secondary Antibodies are available in a variety of formats and conjugate types. When choosing a secondary antibody product, consideration must be given to species and immunoglobulin specificity, conjugate type, fragment and chain specificity, level of cross-reactivity, and host-species source and fragment
Variations in the ability of homogeneous antibodies to absorb group a allotype antisera suggest that these V H region allotypes comprise a spectrum of specificities. While no homogeneous antibody tested would completely absorb antisera to the group a specificities, the total IgG preparations from individual rabbits was capable of doing so, including preimmune IgG from the rabbits that produced the homogeneous antibodies. Differences in the serologic reactivities of homogeneous antibodies indicate that each possesses only a portion of the spectrum of the allotypic specificities expressed by the total IgG ...

A system for production of recombinant Fc fragments of human IgG in Escherichia coli has been developed to allow for structural and functional studies of human Fc. The genes for the Fc fragments of human IgG subclasses 1 and 3, designated Fc(1) and Fc(3), were cloned from a human spleen cDNA library. The interactions to Staphylococcal protein A (SpA), a bacterial Fc receptor, that interacts with human IgG-Fc(1), but not with human IgG-Fc(3), were analyzed. To corroborate the involvement of amino acid residues in Fc, responsible for these differences in binding, two Fc variants were constructed; Fc(1(3)) and Fc(3(1)), each containing an isotypic dipeptide substitution. Production levels in E. coli of 1-10 mg/l of secreted Fc proteins, covalently linked as dimers, were routinely obtained. SpA-binding analyses of all four Fc variants using biosensor technology, showed that Fc(1) and Fc(3(1)) interact with SpA, while Fc(3) and Fc(1(3)) lack detectable SpA binding. The rendered SpA binding of the Fc ...

There is longstanding evidence for a role of immunoglobulin (Ig)G in protection against malarial disease and infection. IgG1 and IgG3 have been shown to be particularly efficient at associating with monocytes in potentially protective mechanisms (i.e. antibody-dependent cellular inhibition, opsonization and phagocytosis). Conversely, there is some evidence that IgG2 (and possibly IgG4) antibodies may be antagonistic to this protection. The protective effect of IgG subclass antibody activity present before the beginning of a malaria transmission season (preseason antibody levels) against severe malaria has not been tested in longitudinal studies. We measured IgG class and subclass antibody levels specific to crude Plasmodium falciparum lysates by enzyme linked immunosorbent assay in a case-control study of 76 children on the coast of Kenya. The mean optical density values for both IgG class and subclass antibodies were not significantly different between the children who developed severe malaria ...
IgG subclass levels of sera from 26 patients with juvenile chronic arthritis (JCA) were determined by means of mouse monoclonal antibodies. Patients were divided into three groups according to clinical activity of the disease: active disease, partial remission, and remission. One hundred and sixty four age matched, healthy children served as controls. IgG subclass concentrations were log transformed, and a robust regression method was applied to obtain expected values for the different ages. We found a significant increase of IgG3 (p less than 0.0001), IgG1 (p less than 0.002), and IgG2 (p less than 0.035) in JCA sera, while IgG4 values did not differ significantly from those of controls. When patients were divided according to clinical activity significant increases of IgG2 and IgG4 were observed in the patients in partial remission. Our data suggest that differential increase of IgG subclasses during the courses of JCA may be of relevance to the pathogenesis of the disease. ...
S. pyogenes has to employ specific strategies to avoid the action of opsonizing IgG antibodies during infection. The streptococcal cysteine proteinase IdeS represents a tailor-made defense against specific IgG antibodies (1, 12, 13, 22-25) and is widely expressed by clinically important serotypes (e.g., M1, M3, M4, and M12), as well as in newly validated serotypes, e.g., M122 (2) suggesting an important role for IdeS during S. pyogenes infections.. The main focus of this study was to characterize the immune response towards the IgG endopeptidase IdeS in acute-phase and convalescent-phase serum samples from patients suffering from streptococcal disease. In accordance with previous data (3, 12, 13), detectable levels of antibodies against IdeS were found in all samples investigated. The neutralizing abilities of these antibodies varied notably between different patient samples, but consistent results were obtained for patients suffering from pharyngotonsillitis and erysipelas, revealing that ...
Background/Aims: Primary biliary cirrhosis (PBC) is characterised by the presence of immunoglobulin (Ig) G antimitochondrial antibodies (AMA), which are routinely detected by indirect immunofluorescence (IFL) using composite rodent tissue substrate. The IgG subclass distribution and clinical significance of IFL-detected AMA in patients with PBC have not been previously studied in detail.. Methods: We have examined IgG subclass-specific AMA detected by IFL on rodent liver, kidney and stomach tissue substrate using affinity-purified IgG subclass monospecific antisera as revealing reagents in 95 AMA-positive PBC patients from Greece.. Results: AMA of any of the IgG1, IgG2 or IgG3 subclasses were present in 89/95 (93.7%) patients. Among those 89, 55 (61.8%) had IgG1, 2, 3 AMA positivity; eight (9%) had IgG1, 2; seven (7.9%) had IgG2, 3; eight (9%) had IgG1, 3; nine (10.1%) had IgG1 subclass and two (2.2%) single IgG3 AMA reactivity. IgG4 AMA was absent. IgG3 titres were higher than IgG2 and IgG1 ...
The ability of monoclonal antibodies (MAbs) to passively cure an influenza virus pneumonia in the absence of endogenous T- and B-cell responses was investigated by treating C.B-17 mice, homozygous for the severe combined immunodeficiency (SCID) mutation, with individual monoclonal antiviral antibodies 1 day after pulmonary infection with influenza virus PR8 [A/PR/8/34 (H1N1)]. Less than 10% of untreated SCID mice survived the infection. By contrast, 100% of infected SCID mice that had been treated with a single intraperitoneal inoculation of at least 175 micrograms of a pool of virus-neutralizing (VN+) antihemagglutinin (anti-HA) MAbs survived, even if antibody treatment was delayed up to 7 days after infection. The use of individual MAbs showed that recovery could be achieved by VN+ anti-HA MAbs of the immunoglobulin G1 (IgG1), IgG2a, IgG2b, and IgG3 isotypes but not by VN+ anti-HA MAbs of the IgA and IgM isotypes, even if the latter were used in a chronic treatment protocol to compensate for ...

Endpoint immunoglobulin G (IgG) titers and cytotoxic T-lymphocyte (CTL) activities were identical between mice immunized via the intramuscular and epidermal (gene gun) routes with 100 and 1 micrograms, respectively, of an influenza virus nucleoprotein (NP) expression vector. However, examination of the relative levels of two IgG subclasses demonstrated that muscle inoculation resulted in predominantly IgG2a responses, whereas gene gun immunization yielded a preponderance of IgG1 antibodies. Inasmuch as these data suggested that muscle inoculation and gene gun delivery elicited Th1-like and Th2-like responses, respectively, gamma interferon release profiles from antigen-stimulated splenocytes were remarkably similar between these groups. Interleukin-4 (IL-4) production assays, on the other hand, revealed qualitative differences that could be correlated with the divergent IgG subclass data. Waning gamma interferon production in gene gun-immunized animals was countered by a marked increase in IL-4 ...

Background/Objectives: The hallmark of cystic fibrosis (CF) is chronic lung inflammation. The severity of lung disease is closely correlated with immunoglobulin G (IgG) levels. Beyond its contribution to the bone health, the importance of vitamin D has not been fully recognized owing to the lack of human studies providing evidence of its benefit. In the context of the recently described immunomodulatory functions of vitamin D, we aimed to assess the relationship between vitamin D and IgG levels. Subjects/Methods: Eight hundred and ninety-six CF patients were included (0.53-65.9 years) from seven centers in Denmark, Norway and Sweden.

Bacillus anthracis, the causative agent of anthrax, is surrounded by an antiphagocytic capsule composed of poly-£^-D-glutamic acid (£^DPGA). Antibodies directed against the £^DPGA capsule are opsonic and protective, which makes the capsule an attractive target for vaccine development. However, antibodies of different IgG subclasses differ in their ability to activate effector functions, including activation of complement and phagocytosis. In addition, recent studies found differences in affinity and protective activity between variable region identical IgG subclass switch monoclonal antibodies (mAbs) directed against microbial capsules or outer membrane proteins. We recently generated six mAbs against the £^DPGA capsule and found that only mAbs of IgG3 subclass were protective in a murine model of inhalational anthrax. In order to investigate the role of IgG subclass to protective activity against anthrax, the goal of the study was to generate a full IgG subclass switch family (IgG3 ,,³ ...
Objective: Intravenous immunoglobulin (IVIG) is a human polyclonal IgG preparation developed for the treatment of patients with primary immunodeficiency (PID). Because of the anti-inflammatory and immunomodulatory effects of IVIG, beyond PID now IVIG is widely used in autoimmune and inflammatory diseases. The aim of this study was to determine the demographic characteristics of patients treated with IVIG treatment in the pediatric infectious diseases clinic, and to evaluate the indications, side effects and treatment outcomes of IVIG treatment. ...

Immunoglobulin G (IgG) is the only antibody isotype actively transferred across the placenta from around 13 weeks of gestation and increases exponentially during the third trimester such that the concentration of IgG in the newborn infant is similar to, or exceeds, that in the mother. IgG provides passive immunity to the infant in the first months of life.. The neonatal Fc receptor facilitates transcytosis of maternal IgG. IgG is transferred from maternal blood across the syncytiotrophoblast layer of the placenta, initially by endocytosis of IgG. Within the acidic endosome, IgG binds to membrane-bound neonatal Fc receptor, which is then released on the fetal side of the syncytiotrophoblast as the pH returns to physiologic pH. Neonatal Fc receptor is then recycled back to the maternal side of the syncytiotrophoblast to bind further IgG.. There are a number of factors that may affect the efficiency of IgG transcytosis, including gestation, IgG subclass and maternal infection.1 The concentration of ...

The 16-kDa cytosolic antigen of M. tuberculosis was purified to homogeneity by molecular sieving chromatography, and the diagnostic potential of the antigen was evaluated in various categories of patients by enzyme-linked immunosorbent assay (ELISA). The immunoglobulin G (IgG), IgA, and IgM antibody levels to 16-kDa antigen were estimated in the two polar groups, namely, smear- and culture-positive pulmonary tuberculosis (S�C�) patients and healthy subjects (HS). Sensitivities of 62, 52 and 11% with specificities of 100, 97, and 95% were obtained for the three isotypes, respectively. The total number of positives by a combination of the three isotypes was analyzed in the polar groups, and the sensitivity improved to 83% with a specificity of 93%. Even when a combination of IgG and IgA alone was considered, the sensitivity was 82% with a specificity of 97%. Polyethylene glycol precipitation of the circulating immune complex (CIC) in sera was carried out. The CIC-bound antibodies to 16-kDa ...

Author Summary After analysing glycans attached to human immunoglobulin G in 4,095 individuals, we performed the first genome-wide association study (GWAS) of the glycome of an individual protein. Nine genetic loci were found to associate with glycans with genome-wide significance. Of these, four were enzymes that directly participate in IgG glycosylation, thus the observed associations were biologically founded. The remaining five genetic loci were not previously implicated in protein glycosylation, but the most of them have been reported to be relevant for autoimmune and inflammatory conditions and/or haematological cancers. A particularly interesting gene, IKZF1 was found to be associated with multiple IgG N-glycans. This gene has been implicated in numerous diseases, including systemic lupus erythematosus (SLE). We analysed N-glycans in 101 cases with SLE and 183 matched controls and demonstrated their substantial biomarker potential. Our study shows that it is possible to identify new loci that

In this thesis, glycosylation of immunoglobulin G (IgG) was examined in 5818 individuals ranging in age from 16 to 100 years from five different populations - four European populations and a Han Chinese population by using ultra performance liquid chromatography (UPLC) in order to provide a comprehensive overview of changes in IgG glycosylation through lifetime. The results demonstrated that glycan profiles change in a similar way through lifetime across all examined populations. Nearly all IgG glycans were significantly associated with age. Sex differences in age-related changes in IgG glycosylation were observed. The combination of several IgG glycans was able to explain from 30 to 58% of variance in chronological age, with the remaining variance in the glycans attributed to physiological parameters. Analysis of IgG glycosylation in nearly 600 mice from the Collaborative Cross cohort ranging in age from 20 to 80 weeks showed that, generally, only the level of IgG glycan with ...

Anti-Human IgG F(ab)2 Antibody generated in goat recognizes the dimeric Fab portion of the human IgG molecule. Human IgG F(ab)2 is a proteolytic fragment of immunoglobulin G (IgG) obtained by limited digestion with the enzyme pepsin under controlled conditions of temperature, time and pH. F(ab)2 molecules lack the Fc portion of IgG and therefore receptors that bind human IgG F(c) will not bind human IgG F(ab)2 molecules. Secondary Antibodies are available in a variety of formats and conjugate types. When choosing a secondary antibody product, consideration must be given to species and immunoglobulin specificity, conjugate type, fragment and chain specificity, level of cross-reactivity, and host-species source and fragment composition.

Purification of IgG from patients and controls and generation of F(ab)2 fragments. Blood or plasma exchange fluid was obtained from patients with ANCA vasculitis or healthy controls and plasma stored at -80°C. Fibrinogen was precipitated by adding 18 g/100 ml of sodium chloride and IgG was purified with protein G chromatography (GE Healthcare). The endotoxin concentration in the final IgG preparations was measured by Lonza using a LAL kinetic chromogenic assay. For all 30 polyclonal IgGs used, the endotoxin was less than 0.25 eU/250 μg IgG. The concentration of IgG used for all neutrophil and monocyte assays was 250 μg/ml. To generate F(ab)2 fragments, whole IgG was buffer exchanged using PD10 columns into 20 mM sodium acetate and digested using immobilized pepsin (Thermo Fisher Scientific). The F(ab)2 fragments were separated from undigested IgG using protein A affinity columns (GE Healthcare). SDS-PAGE demonstrated the purity of whole IgG and the F(ab)2 fragments. Before all assays, IgG ...
In this study, we describe the clinical features and treatment practices of the largest cohort of IgG4-RD in our locality. After combination of our patients with all other published cases of IgG4-RD from Hong Kong, we analysed 104 cases comprising predominantly older men (mean age, 62 ± 13 years; male-to-female ratio=3:1), which is consistent with other reports.19 20 21 22 Over 95% of patients had serum IgG4 level of ,135 mg/dL and an IgG4:IgG ratio of ,8%. Although these cut-offs are often quoted in the diagnostic criteria for IgG4-RD,4 23 it is important to note that elevated serum IgG4 levels can be seen in a variety of other conditions such as malignancies, infections, or autoimmune disorders. Serum IgG4 level and IgG4:IgG ratio alone have poor specificity and low positive predictive value. The specificity and positive predictive value of serum IgG4 and IgG4:IgG ratio have been reported to be approximately only 0.6 and 0.3, respectively.24 Of note, 4/72 (5.6%) of our patients with ...

In this study, we compared the vasoactive effects of 16 intravenous immunoglobulin (IVIG) products from 10 different manufacturers, in anesthetized rats. Eight of the IVIG preparations showed no hypotensive effects (less than 15% decrease), whereas the other 8 had relatively strong effects (15%-50% decrease). The hypotensive effects correlated with the IgG dimer content of the preparations. Pretreatment of the rats with recombinant PAF acetylhydrolase completely prevented the hypotensive reaction on IVIG infusion, and administration after the onset of hypotension resulted in normalization of the blood pressure ...

TY - JOUR. T1 - Regulation of IgG antibody-dependent cellular cytotoxicity in vitro by IgM antibodies. Mechanism and characterization of effector lymphocytes. AU - Perlmann, H.. AU - Perlmann, P.. AU - Moretta, L.. AU - Ronnholm, M.. PY - 1981. Y1 - 1981. N2 - IgM antibodies have previously been reported to either inhibit or induce antibody-dependent lymphocyte cytotoxicity (ADCC). Here the authors show that human lymphocytes lyse bovine erythrocytes (Eb) in the presence of either IgM or IgG anti-Eb from rabbits. Seven out of 20 IgM preparations (Sephadex G-200) were ADCC-active. IgG-dependent ADCC was inhibited by human IgG but not by IgM. In contrast, IgM ADCC was inhibited by both IgG and IgM. The effector cells in IgM ADCC were a subpopulation of lymphocytes with distinct Fc receptors for both IgG and IgM. Most of them also had sheep erythrocyte receptors. Extensive purification of the ADCC-active IgM antibody preparations indicated that very small amounts of contaminating IgG anti-Eb were ...
Recently, a new dense granule protein (GRA7) from T. gondii was described, and the corresponding gene was characterized (9). To study the potential of this protein for serological assays, the gra7 gene was expressed in E. coliwith a short mTNF fragment and hexahistidine as a fusion partner. The subsequent purification of the recombinant protein allowed evaluation of this antigen as a diagnostic tool. In an indirect IgG ELISA, a sensitivity of 81% and a specificity of 98% were reached. High-titer IgG-positive sera (IF titer, ,1/1,024) were readily detected (100%). IgM-positive sera were detected in 94% of cases, and for chronic-phase sera (IgM negative) the sensitivity was 79%. In general, chronic-stage sera with low IgG titers by IF were more difficult to detect with GRA7. These results were in the same range as those obtained for a recombinant fragment of GRA2 (75% for chronic-phase sera, 82.6% for acute-phase sera) (17) and for Tg34AR (ROP2 fragment; 89% overall sensitivity) (27). The ...

Allergen specific antibodies of the type Immunoglobulin G (IgG) are responsible for the intermediation of allergic reactions of the cytotoxic as well as the immune complex type and for this play an important role in the extended allergy diagnostic. Antibodies, also known as immunoglobulins (Ig), play an important role in the humoral immune response to extrinsic, infectious agents. Furthermore Ig and in particular Ig of the IgG type can be generated to normally harmless antigens, e.g. inhalation antigens or food antigens. A typical disease represents the exogenic allergic alveolities (EAA), which can be caused by occupational exposition of substances in the air. Involved are normally moldy- and bacterial components but also excrements, flours or chemical components which are inhaled as dusts or aerosols during work. Farmer´s lung is caused by Thermophile Actinomycetes in moldy hay. Farmer´s lung, Malt- and Paper worker´s lung as well as Pigeon Breeder´s disease are well known to represent ...
