Evidence shows that psychosocial factors are associated with immunoglobulin G response to medical vaccinations. As yet, there are no reports of whether the earlier immunoglobulin M response is similarly susceptible. This study examined the association between psychological stress, social support and the immunoglobulin M response to vaccination with pneumococcal capsular polysaccharides. Stressful life events in the previous year and customary social support were measured by standard questionnaires at baseline in 74 healthy students (41 females). The response to five common pneumococcal serotypes was assessed at baseline and five-days following vaccination. Social support, particularly tangible social support, was positively associated with the antibody response to two of five serotypes, after controlling for baseline titre. These associations survived adjustment for demographics and health behaviours. There was no association between life events stress and immunoglobulin M response. It appears ...
Abstract An enzyme-linked immunosorbent assay (ELISA) was developed to detect different hantavirus antigens in cell culture; i.e. Puumala (PUU), Hantaan (HTN), and Dobrava (DOB) viruses. The assay was based on binding human serum immunoglobulin M (IgM) antibodies to the solid phase by use of goat anti-IgM antibodies. The captured IgM antibodies were present in the acute phase serum from two patients: one infected in Sweden and the other in Bosnia. Antigens being bound to the solid phase by the human anti-PUU and anti-DOB/HTN IgM antibodies were detected by a broadly reacting polyclonal rabbit anti PUU-recombinant nucleocapsid protein antiserum. The IgM isotype was proven to be at least five times more efficient than IgG when used as the capturing antibody. The sensitivity of the PUU antigen ELISA was approximately 0.5 ng/ml, as measured by titration with a PUU recombinant nucleoprotein antigen. Cell-associated PUU antigen in tissue culture was seen after 48 hr by the PUU-ELISA and after 96 hr by
Japanese encephalitis (JE) virus is a major cause of neurologic infection in Asia, but surveillance has been limited. Three JE immunoglobulin M (IgM) antibody capture enzyme-linked immunosorbent assay kits have recently been developed. The aim of this study was to evaluate their sensitivity, specificity, and usability using 360 acute-phase serum samples containing JE, dengue, or neither IgM antibody. The kits, manufactured by Panbio Limited, Inbios International, Inc., and XCyton Diagnostics Ltd, had high sensitivities of 89.3%, 99.2%, and 96.7%, respectively. The specificities were 99.2%, 56.1%, and 65.3%, respectively. When dengue IgM-positive samples were excluded, the kits had specificities of 98.4%, 96.1%, and 96.1%, respectively. The Panbio kit includes both JE and dengue antigens and appears to have an advantage in settings where dengue virus co-circulates, although further assessments in clinical settings are needed. This information is helpful in considering options for strengthening the
We have identified a set of natural IgM antibodies in human serum that are reactive with protamines, a class of low molecular weight basic nucleoproteins that are synthesized de novo in the postpubertal testis and are unique to sperm. Those antibodies were detected by ELISA in significant titer in all of 100 sera of normal adult males and females and in 26 of 28 sera of normal pediatrics aged 7 d to 2 yr. Commonality between the protamine-reactive IgM antibodies of pediatric and adult sera was established by the demonstration of similarity in antigen recognition and reaction kinetics. Therefore, the role of protamines as either immunogenic stimulus or antigenic target of that set of natural antibodies is not likely. The antigenic site recognized by the protein-reactive serum IgM antibodies was characterized by comparison with the pattern of antigen recognition by a monoclonal antibody to human sperm protamines (HPmAb). By the use of synthetic peptides simulating the amino acid sequences of ...
TY - JOUR. T1 - Preparation of antigen-binding monomeric and half-monomeric fragments from human monoclonal IgM antibodies against colorectal cancer-associated antigens. AU - Ditzel, Henrik. AU - Erb, Karin. AU - Leslie, Graham. AU - Jensenius, Jens Chr. PY - 1993/1/1. Y1 - 1993/1/1. N2 - The large size of human IgM monoclonal antibodies (MAbs) may impede the tumor-localizing capacity. A procedure is described for the preparation of antigen-binding monomeric (IgMm) and half-monomeric (IgMI½m fragments from two human IgM MAbs, COU-1 and D4213. The fragments retained binding activity against colon carcinoma. Six different reducing reagents (dithiotreitol, 2-mercaptoethanol, 2-mercaptoethylamine, L-cysteine, metabisulphite, ascorbic acid) were investigated over a range of concentrations, pHs, and incubation periods. The reduced IgM preparations were alkylated with iodoacetamide and fractionated by high-performance gel permeation chromatography. The fractions were directly collected on ELISA plates ...
Delayed and variable antibody responses to HCV make it difficult to diagnose acute HCV infection reliably. Immunoglobulin (Ig)M and IgG anti-HCV may be observed simultaneously as disease persists. IgM plays a key role in mixed cryoglobulinemia (MC), an immune complex disease strongly associated with persistent HCV infection. In MC, clonal or oligoclonal IgM rheumatoid factors facilitate the deposition of immune complexes in small blood vessels and tissue, leading to inflammation, complement activation and tissue damage. Clonally expanded IgM(+)κ(+) B-cells expressing rheumatoid factor-like IgM are abundant in many HCV patients with MC. The observation that identical or similar IgM antibodies are expressed in different patients clonally expanded B-cells supports the hypothesis that MC is driven by antigen-specific B-cell activation, rather than polyclonal B-cell activation or HCV replication in B-cells. More study is required to identify the antigens that drive the development of MC.

Guidance for the deployment of the Emergency Use Approval (EUA) Zika virus testsOn March 25, CMS provided guidance regarding the deployment of the EUA Zika virus tests, approved by CLIA, to state and local Public Health Laboratories (PHL) by the CDC. Two Zika virus tests with corresponding protocols have been developed by the CDC for use by state PHLs and have received EUA by the FDA. If test kits are noted during surveys, Regional Offices (RO) must confirm that the Zika Immunoglobulin M Antibody Capture Enzyme-Linked Immunosorbent Assay and/or the Trioplex Real Time RT-PCR Assay was verified by each laboratory per the CDC protocol, and that corresponding CLIA policies and procedures are in place to ensure readiness and compliance in the event of an outbreak. Upon receipt of the Zika virus test system and corresponding instructions and information, state PHLs will verify the developed test specifications in their laboratory per the CDCs guidance.
Summary In July 2016, CDC issued Interim Guidance for Health Care Providers Caring for Pregnant Women with Possible Zika Virus Exposure - United States, July 2016 (https://www.cdc.gov/mmwr/volumes/65/wr/mm6529e1.htm) that includes Zika virus immunoglobulin M (IgM) testing of pregnant women. However, some flavivirus infections can result in prolonged IgM responses (,12 weeks) that make it difficult to determine the timing of infection, especially in testing of asymptomatic people. Emerging epidemiologic and laboratory data indicate that Zika virus IgM can persist beyond 12 weeks in a subset of infected people. Therefore, detection of IgM may not always indicate a recent infection. Although IgM persistence could affect IgM test interpretation for all infected people, it would have the greatest effect on clinical management of pregnant women with a history of living in or traveling to areas with Zika virus transmission. Pregnant women who test positive for IgM antibody may have been infected with ...
Immunoglobulin M (IgM) is the largest circulating antibody molecule in humans. It consists of a heavy chain (?-chain) and a light chain (κ- or λ-chain), as well as 5 base units and 10 binding sites, though it cannot bind all 10 simultaneously because of steric hindrance. IgM chain C refers to the constant region of the IgM heavy chain that is involved in immune regulation. IgM forms polymers by covalently linking multiple immunoglobulins together with disulfide bonds. It normally exists as a pentamer, but occasionally as a hexamer. Because of its polymeric nature, IgM has high avidity, and it is especially effective at complement activation. Due to its large size, IgM does not diffuse well, and it is found in the interstitium in very low amounts. IgM is mainly found in serum; however, because of the J chain, it is also important as a secretory immunoglobulin. IgM is the first immunoglobulin expressed by mature B cells, and it normally appears early in the course of an infection and does not ...

Lymphocyte recognition of characteristic structural features in microbial DNA may contribute to immune defense by promoting protective immune responses. The dinucleotide CpG is significantly under-represented in vertebrate DNA and is usually methylated. In contrast, CpG dinucleotides are generally present at the expected frequency in bacterial DNA and are unmethylated. These unmethylated CpG motifs induce B cells to secrete IL-6 and IgM, and can induce NK and CD4+ T cells to produce the immunoregulatory Th1 cytokine, IFN-gamma. IFN-gamma inhibits IgM secretion that is triggered by a different bacterial product, LPS. The present study demonstrates that in contrast to its antagonistic interaction with LPS, IFN-gamma causes a dose-dependent increase in the level of IgM secretion induced by CpG DNA. Like IgM secretion, B cell secretion of IL-6 more than doubles after the addition of exogenous IFN-gamma. Mice with disrupted IFN-gamma genes produced less than half as much IL-6 and IgM in response to ...

Effect of anti-γ chain and anti-µ chain on secondary antibody response of rabbit spleen cells was studied in vitro. Spleen cells from rabbits primed with dinitrophenylbovine γ globulin (DNP-BGG) were stimulated in vitro with the antigen either in the presence or absence of anti-heavy chain antibody. After 24 hr of incubation, the cells were washed and cultured in the absence of the antigen. Antibody response was evaluated by enumerating IgG and IgM antibody producing cells and by measuring anti-DNP antibodies in culture media. It was found that anti-γ chain suppressed both IgG and IgM antibody response, while anti-µ chain suppressed only IgM antibody response. When the primed cells were cultured without antigen stimulation, IgM antibody producing cells increased after 3 days culture. The response was also suppressed by treatment of the cells by either anti-γ or anti-µ chain. The treatment with anti-heavy chains did not inhibit secretion of antibodies from antibody producing cells. It ...

Objectives Increased rates of infection with Toxoplasma gondii have been found in individuals with schizophrenia as compared to control groups but this issue has not been studied in mania. Methods We measured immunoglobulin G (IgG) and IgM class antibodies to T.gondii in 57 individuals with mania who were assessed at up to three time-points. We also measured these antibodies in 743 individuals in other psychiatric groups and in 314 non-psychiatric controls. T.gondii antibody levels were compared among groups by multivariate analyses. IgG class and IgM class antibodies to cytomegalovirus were also measured in the same samples. T.gondii antibody levels were also compared over time in the mania group. Results The mania group had a significantly elevated level of IgM antibodies to T.gondii as compared to the control individuals without a psychiatric diagnosis [odds ratio (OR)=2.33, pOR=2.32, pT.gondii were not found in individuals with the other psychiatric diagnoses.

Introduction: It is hypothesized that IgM antibodies to oxidized LDL are anti-atherogenic. Myeloperoxidase from plaque-infiltrating neutrophils catalyzes the production of hypochlorite (HOCl), which oxidizes LDL. Here we study the IgM response to HOCl-modified LDL in comparison to titers of T15 clonotypic natural antibodies. Methods: Plasma of LDLR-/- mice fed a normal chow or high-fat diet was obtained after 6 and 16 weeks. The IgM responses to HOCl-modified LDL and T15 clonotypic natural IgM antibodies were measured by ELISA. Results: The IgM levels in response to HOCl-modified LDL increased dramatically in the atherosclerotic group after introduction of the high-fat diet, but not in mice on normal chow. The natural IgM T15 clonotypic antibody titers revealed a more moderate increase during atherogenesis. Conclusion: Our results show that during atherogenesis there is a strong induction of IgM antibodies to HOCl-modified LDL particles. Whether these induced IgM antibodies are pro- or ...
Major depression and chronic fatigue syndrome (CFS) are accompanied by signs of oxidative and nitrosative stress (O&NS) and an inflammatory response. Phosphatidyl inositol (Pi) is thought to play a role in depression. The aim of the present study is to examine whether depression and CFS are characterized by an IgM-mediated immune response directed against Pi. Toward this end, this study examines the serum IgM antibodies directed against Pi in 14 patients with major depression, 14 patients with CFS, 14 subjects with partial CFS, and in 11 normal controls. We found that the prevalence and mean value for the serum IgM levels directed against Pi were significantly greater in patients with major depression and CFS than in normal controls and patients with partial CFS. There were significant and positive correlations between serum IgM levels directed against Pi and two symptoms of the FibroFatigue Scale, i.e. fatigue and depression. The results show that an IgM-related immune response directed against ...

Waldenstroms Macroglobulinemia Symptom: A few patients dont have side effects. For the individuals who have side effects, the most well-known ones are shortcoming, serious weakness, seeping from the nose or gums, weight reduction, and wounds or other skin sores. Seriously large amounts of IgM can prompt hyperviscosity disorder, in which the blood turns out to be unusually thick. Waldenstroms Macroglobulinemia Symptoms of this disorder incorporate visual issues (e.g., obscuring or loss of vision) and neurological issues (e.g., migraine, discombobulation, vertigo). Amid a physical exam, a specialist might likewise discover swelling of the lymph hubs, spleen, and/or liver.. Waldenstroms Macroglobulinemia Causes:. Waldenstroms macroglobulinemia is a consequence of a condition called lymphoplasmacytic lymphoma. The reason for the overproduction of the IgM counter acting agent is obscure, yet specialists trust it is made by lymphoma cells. Overproduction of Waldenstroms Macroglobulinemia Causes ...
A solid-phase immune electron microscopy method that uses protein A, goat anti-human immunoglobulin M (IgM), and human serum is described. Evaluation of the method with different immunoglobulin fractions showed that human IgM constituted the major virus capture antibody. The method appeared to distinguish between two Norwalk-like virus serotypes and demonstrated specific IgM responses to these serotypes in infected individuals. Further work is being carried out to define the relationship of these two serotypes to the previously described Norwalk agent (A. Z. Kapikian, R. G. Wyatt, R. Dolin, T. S. Thornhill, A. R.

1Department of Pediatrics, Hitachiomiya Saiseikai Hospital, and 2Department of Viruses, Ibaraki Prefectural Institute of Public Health, Ibaraki, Japan. E-mail: [email protected] or [email protected] Measles is a highly contagious viral infection associated with clinical symptoms such as fever, cough, conjunctivitis, coryza, eruption and increased serum immunoglobulin M (IgM) antibodies. A clinical diagnosis is easily established when the chain of infection can be followed. However, Japan is currently experiencing sporadic measles outbreaks, which complicate the establishment of diagnosis. Furthermore, other exanthematous infections such as rubella, human parvovirus B19, human herpesvirus 6 (HHV-6) and HHV-7 present with clinical symptoms and IgM antibody levels similar to those in measles. Therefore, real-time polymerase chain reaction virogene testing has been part of Japans standard diagnostic protocol for measles since 2010. This report presents two pediatric cases clinically resembling ...

Antiglycolipid IgM antibodies are recognized to induce formation of extended or wide-spaced myelin, a distinctive type of dysmylination seen as a a repeat period ~2X or 3X regular, observed in diseases including multiple sclerosis also. to look at. Wide spacing tended to involve the external layers from the sheath and perhaps alternated with normally spaced lamellae. An attribute not noticed previously includes multiple extended myelin lamellae in a single sector of the sheath constant with normally spaced lamellae in another, leading to variant in sheath width across the axonal circumference. This unequal distribution of wide-spaced lamellae can be most simply described predicated on incorporation of IgM substances into immature sheaths during myelin development and indicates a style of CNS myelinogenesis more technical than basic spiraling. The periaxonal space under no circumstances shows widening of the kind, but the interface with adjacent myelin sheaths or oligodendrocytes may. Thus, wide ...

Seasons Greetings to All, I need to purify some IgM isotype monoclonal antibodies to allow me to conjugate them to fluorochromes. I do not have access to HPLC or FPLC. I have seen some info from a company called Sterogene that sells a pre-packed column that is designed to purify IgM mabs, has anyone experience with this product? It is quite expensive and I have already had my budget burnt by another commercial product that was inadequate, so all comments and advice would be appreciated.

We have investigated the importance of glycosylation in determining the function of membrane-bound and secreted immunoglobulin M (IgM). Hickman and Kornfeld (1978) previously observed that glycosylation is required for IgM to be secreted by 104E, a mouse plasma cell tumor. In order to determine whether this requirement is a general one for all forms of IgM, we have used WEHI 279.1, a mouse B lymphoma that synthesizes both the membrane and secreted forms of IgM. In the presence of 5 microgram/ml tunicamycin (Tm), glycosylation of both membrane and secreted IgM is at least 90% inhibited, but total protein synthesis is equivalent in control and Tm-treated cells. Despite the absence of carbohydrate, IgM molecules are properly assembled into monomers for membrane localization. Cells whose surfaces have been stripped of membrane IgM by treatment with anti-mu antibody resynthesize the IgM equally well in the presence or absence of Tm. It is more surprising that the assembly of IgM into pentamers and the

Results The results showed that ARG098 was well-tolerated and no serious adverse events were observed. Total 33 adverse events (AEs) in 19 patients, and drug-related AEs in 9 patients which included non-clinical hepatological and cardiological findings were confirmed, however those were occurred in low frequency and the severity was all mild. ARG098 serum concentration was below the limit of qualification level (,2.5 ng/mL). The clinical improvement was observed in most of the patients. Knee pain score by visual analogue scale (VAS) showed improvement at some assessment visits. The pain VAS of target knee was statistically improved at day 7 in 0.01 μg (-32.3±11.3 mm), day 14 and 28 in 1 μg (-27.3±19.3 mm, -27.5±19.6 mm) and day 7 and 14 in 10 μg (-37.4±26.0 mm, -35.4±26.0 mm) groups. The assessment with MRI showed improvement in more than half patients in 0.03 to 3 μg groups, and no deterioration was observed in all 43 patients.. ...

Nearly all immune-competent individuals will develop an immune response following SARS-CoV-2 infection. Like infections with other pathogens, SARS-CoV-2 infection elicits development of IgM and IgG antibodies, which are the most useful for assessing antibody response because little is known about IgA response in the blood.. Antibodies in some persons can be detected within the first week of illness onset. In SARS-CoV-2 infections, IgM and IgG antibodies can arise nearly simultaneously in serum within 2 to 3 weeks after illness onset. Thus, detection of IgM without IgG is uncommon. How long IgM and IgG antibodies remain detectable following infection is not known. It is also important to note that some persons do not develop detectable IgG or IgM antibodies following infection. Thus, the absence of detectable IgM or IgG antibodies does not necessarily rule out that they could have previously been infected.. In addition, development of neutralizing antibodies can also be assessed. Neutralizing ...
What Is Waldenstroms Macroglobulinemia Disease? Your immune system produces cells that protect your body against infection. One such cell is the B lymphocyte, which is also known as a B cell. B cells are made in the bone marrow. They migrate and mature in your lymph nodes and spleen. They can become plasma cells, which are … Continue reading. ...

Despite improvements in antimicrobial therapy and supportive care, sepsis is still a major public health issue. Recently, CD100 and its receptor in the immune system CD72 were shown to play a major role in immune regulation. The purpose of this study was to investigate the expression and clinical correlations of CD72 and CD100 on circulating lymphocytes of septic patients. In total, 24 healthy controls and 54 septic patients were enrolled in this study. Considering the focus of the current study was on the immunosuppressive phase of sepsis, blood samples of patients were collected at days 3-4 after the onset of sepsis. The levels of CD72 and CD100 expression on circulating lymphocytes were measured by flow cytometry and serum IL-6, IL-10, and immunoglobulin M levels were determined by enzyme-linked immunosorbent assay. Our results showed that the levels of CD100 expression on T cells and CD72 expression on B cells were significantly lower in septic patients. Similarly, a significant decrease in the

The diagnosis of parasitic infections is definitively made by the identification of parasites in host tissue or excreta. The detection of antibodies can be very useful as an indicator that an individual has been infected with a specific parasite. A positive result for a person with no exposure to the parasite prior to recent travel in an area where disease is endemic may be interpreted as indicating recent infection. In general, the detection of antibodies to parasitic diseases indicates only infection at some indeterminate time and not necessarily an acute or current infection. The detection of specific immunoglobulin M (IgM) and IgA antibodies may be of value in determining the approximate time of initial infection with Toxoplasma gondii, but it is not recommended for any other parasitic disease. The diagnosis of human intestinal protozoa depends on microscopic detection of the various parasite stages in feces, duodenal fluid, or small intestine biopsy specimens.

What reasons Waldenstroms Macroglobulinemia like numerous different diseases are obscure despite the fact that it is trusted that a change in DNA could be a reason. Despite this absence of assurance on the Waldenstrom Macroglobulinemia Causes there are thought to be elements which improve the probability of building up the malady. The lions share of instances of waldenstroms macroglobulinemia happen in those beyond 50 years old and the normal time of event is 61. Occurrence of the ailment is twice as much in men than ladies. The condition is likewise acquired which implies that those with family who have Waldenstroms or a kind of lymphatic tumor are more prone to get the condition.. Symptoms A first conclusion of Waldenstroms is mind boggling in light of the fact that there is typically an unlucky deficiency of Waldenstroms Macroglobulinemia Symptoms right off the bat. Typically the first sign of Waldenstroms originates from routine examinations indicating atypical results. These ...
