The intestine is the largest lymphoid tissue in the body. One striking feature of intestinal immunity is its ability to generate great amounts of noninflammatory immunoglobulin A (IgA) antibodies that serve as the first line of defense against microorganisms. The basic map of IgA production includes induction of mucosal B cells in the Peyers patches, circulation through the bloodstream and homing to intestinal mucosa of IgA-commited plasma cells, and local antibody production for export across the intestinal membranes. Multiple cytokines, including TGF-{beta}, IL-10, IL-4, IL-5, and IL-6, are required to promote IgA class switching and terminal differentiation process of the B cells. Secreted IgA promotes immune exclusion by entrapping dietary antigens and microorganisms in the mucus and functions for neutralization of toxins and pathogenic microbes ...
Virus-like particles (VLPs) provide a well-established vaccine platform; however, the immunogenic properties acquired by VLP structure remain poorly understood. In this study, we showed that systemic vaccination with norovirus VLP recalls human IgA responses at higher magnitudes than IgG responses under a humanized mouse model that was established by introducing human PBMCs in severely immunodeficient mice. The recall responses elicited by VLP vaccines depended on VLP structure and the disruption of VLP attenuated recall responses, with a more profound reduction being observed in IgA responses. The IgA-focusing property was also conserved in a murine norovirus-primed model under which murine IgA responses were recalled in a manner dependent on VLP structure. Importantly, the VLP-driven IgA response preferentially targeted virus-neutralizing epitopes located in the receptor-binding domain. Consequently, VLP-driven IgA responses were qualitatively superior to IgG responses in terms of the ...

Immunoglobulin A (IgA) has a key part in defending mucosal surfaces against assault by infectious microorganisms. serum IgA, which is principally monomeric, and secretory forms of IgA are capable of neutralising and eliminating pathogens through a range of mechanisms, including triggering the IgA Fc receptor known as FcRI or CD89 on phagocytes. The effectiveness of these removal processes can be highlighted by the actual fact that different pathogens possess evolved systems to thwart such IgA-mediated clearance. As the structureCfunction human relationships governing the assorted capabilities of the immunoglobulin class enter into significantly clear concentrate, and methods to circumvent any natural limitations are created, IgA-based monoclonal antibodies are arranged LY2801653 dihydrochloride to emerge as powerful and fresh options in the therapeutic arena. and of the genital system, such as for example type 2 IgA1 protease, while for the sort 2 enzyme, different C3 residues expected to be ...

We have evaluated a novel B-cell FluoroSpot assay for the analysis of antibody responses in healthy individuals vaccinated intramuscularly with Influenza A (H1N1) antigen (Pandemrix®, GlaxoSmithKline). Using the FluoroSpot assay and an ELISpot assay run in parallel for comparison, we measured the frequency of cells secreting antigen-specific as well as total IgG or IgA antibodies seven days post vaccination. The assays were based on high affinity monoclonal antibodies for capture and detection of human IgG and IgA. Whereas conventional ELISpot analyzes IgG- and IgA-secreting B cells separately, fluorescent detection enabled simultaneous enumeration of B cells secreting IgG or IgA in the same well. The FluoroSpot protocol was also simpler as the assay could be performed without the need for an amplifying detection step. While having all the advantages of a conventional ELISpot assay, including high sensitivity, robustness and ease of performance, the FluoroSpot assay adds further value in reducing costs

| The immune system is one of the hardest working systems in the body. It is constantly working in the background, searching the body for bacterias and any potentially harmful pathogens. The first attacker in the line of defense is secretory IGA (SIgA). SIgA is the predominant immunoglobulin that is produced in the lining of the gut. SIgA Hard At Work Considering that the majority of the immune system is housed in the gut, the intestinal mucosa has to be able to recognize pathogens and other foreign objects to effectively keep them out. As previously mentioned, the first one on the scene is SIgA. This immunoglobulin differs from the other immunoglobulins the body produces (IgE, IgG, and IgM) in the way that it does not target a specific invader.

To test the hypothesis that IgA nephropathy can result from a mucosal immune response, mice were orally immunized with one of three protein antigens for 14 wk. Such mice exhibited an essentially pure mucosal antibody response characterized by specific IgA-producing plasma cells in exocrine sites and specific IgA antibodies in serum. Furthermore, 73% of immunized mice had IgA and 88% had immunogen deposited in the glomerular mesangium, and 64% of immunized mice examined ultrastructurally had electron-dense mesangial deposits. All three were present concurrently in 57% of the immunized mice. No differences in regard to IgG or IgM were observed between immunized and control mice for any of these parameters. Mucosal immunization therefore can result in a specific immune response that leads to mesangial deposition of immune complexes containing IgA antibody. In its fundamental features the experimental renal lesion resembles that seen in the human disease IgA nephropathy. ...

Y1 - 2015/6/1. N2 - Aim Data on clinicopathological features, treatment and outcomes of IgA nephropathy (IgAN) in elderly patients are limited. Methods Native kidney biopsies with a pathological diagnosis of IgAN (n = 1084) from Mayo Clinic Rochester in the years 1994-2013 were examined. After exclusion of the secondary IgAN, 45 elderly IgAN patients (age ≥65 years) were identified. One hundred sixty-two younger adults (age 18-64 years) with IgAN were randomly selected for comparison. Results Compared with younger adults, elderly patients showed a higher rate of chronic hypertension (62.2 vs 27.2%), higher pulse pressures (65 ± 17 vs 51 ± 15 mmHg), requiring greater number of antihypertensive medications (2.5 ± 1.2 vs 1.7 ± 0.7) and lower blood haemoglobin (11.1 ± 2.3 vs 12.7 ± 2.1 g/dL) at time of ...

TY - JOUR. T1 - Immune components of the intestinal mucosae of ageing and protein deficient mice. AU - Lim, T. S.. AU - Messiha, N.. AU - Watson, R. R.. PY - 1981/1/1. Y1 - 1981/1/1. N2 - The studies were designed to investigate the effect of ageing and low protein (4%) diet on antibody-dependent cell-mediated cytotoxicity (ADCC) and IgA concentration in the intestine. Both ADCC activity and IgA concentration were shown to reach mature levels at 17 weeks old. The effect of ageing was greater on ADCC activity which showed a drastic drop in activity at 75 weeks old than IgA which had only a slight decline in concentration at this age. The low protein diet has a greater suppressive effect on IgA concentration than on ADCC activity. As the duration of feeding low protein to the young mice increased, greater decline in IgA concentration in the intestine was observed. There was, however, no significant difference from the normal mice in ADCC activity and IgA concentration of aged and adult mice given ...

The effect of rat immunoglobulins and immune complexes on the locomotor function of rat polymorphonuclear leukocytes (PMN) was investigated in vitro. Rat immunoglobulin G1 (IgG1), IgG2a, IgG2b, and IgA monoclonal antibodies specific for the dinitrophenyl hapten were used. Both monomeric and polymeric IgA showed chemotactic activity in a dose-dependent manner. IgG1 and IgG2b also induced a dose-dependent locomotor response of PMN, but the nature of the induced migration was chemokinetic (enhancing random migration). IgG2a was chemotactic and induced maximal migration at a relatively low concentration. IgG1- and IgG2b-immune complexes induced stronger migration than antibody alone; however, IgA- and IgG2a-immune complexes did not. IgA was shown to modify the chemotactic movement of PMN induced by N-formylmethionyl-leucyl-phenylalanine (FMLP). In the presence of both IgA and FMLP in the lower chamber, the migration towards suboptimal concentrations of FMLP was enhanced. By contrast, IgA in the ...
Human colostrum contains many bioactive factors that must promote the development of intestinal mucosal immunity in infants. Especially, the presence of certain cytokines such as transforming growth factor (TGF)-β or IL-10 has been of great interest for IgA production as a function of mucosal immune response. In the present study, we attempted to investigate whether unidentified factors inducing generation of IgA-producing cells from naive B cells might exist in colostrum. For this purpose, colostrum samples were directly added to a culture consisting of naive B cells and dendritic cells from cord blood and CD40 ligand-transfected L cells, comparing with recombinant IL-10 (rIL-10) and/or rTGF-β. It was noted that most colostrum samples alone were able to induce IgA-secreting cells at higher levels than rIL-10 and/or rTGF-β. IgA-inducing activity of colostrum was abolished by neither anti-neutralizing mAbs against IL-10 nor TGF-β, though partially by anti-IL-6 mAb. We prepared partially ...
Secretory IgA (SIgA) antibodies directed against the O-antigen (O-Ag) component of lipopolysaccharide are the primary determinants of mucosal immunity to enteric bacterial pathogens, such as Shigella flexneri and Salmonella enteric serovar Typhimurium. In this report, we demonstrate that monoclonal IgA Abs against the O-Ag are effective inhibitors of the bacterial type 3 secretion systems (T3SS) required for bacterial entry into intestinal epithelial cells. While these Abs did not affect bacterial viability, they did transiently de-energize both S. flexneri and S. Typhimurium, possibly accounting for the paralysis that has been observed in the case of S. Typhimurium, following Ab treatment. O-Ag specific IgA Abs also elicited long lasting ultrastructural changes in the bacterial outer membranes, suggesting that S. flexneri and S. Typhimurium made undergo specific adaptations in response to SIgA. These findings may have implications for understanding immune surveillance in the gut. We have ...

Our immune system produces a number of different immunoglobulin complexes to defense against infections, allergens, etc. Among these are IgA, IgG, IgM, and IgE. In case of IgA Nephropathy, something appears to go wrong with either the form of the IgA immune complex itself, or with their production and clearance within the body, or the both. As a result, the immune complex will deposit in the glomeruli and lead to damages to the renal functional cells and tissues ...
Diarrheal diseases represent a major health burden in developing countries. Parenteral immunization typically does not induce efficient protection against enteropathogens because it does not stimulate migration of immune cells to the gut. Retinoic acid (RA) is critical for gut immunity, inducing upregulation of gut-homing receptors on activated T cells. In this study, we have demonstrated that RA can redirect immune responses elicited by s.c. vaccination of mice from skin-draining inguinal LNs (ingLNs) to the gut. When present during priming, RA induced robust upregulation of gut-homing receptors in ingLNs, imprinting gut-homing capacity on T cells. Concurrently, RA triggered the generation of gut-tropic IgA+ plasma cells in ingLNs and raised the levels of antigen-specific IgA in the intestinal lumen and blood. RA applied s.c. in vivo induced autonomous RA production in ingLN DCs, further driving efficient induction of gut-homing molecules on effector cells. Importantly, RA-supplemented s.c. ...

Researchers from the UCSD Superfund Research Center in an impressive collaborative study, have found that chronic liver inflammation can also promote cancer by suppressing immunosurveillance - a natural defense mechanism in which its thought the immune system suppresses cancer development.. The study, led by Drs. Michael Karin (Distinguished Professor of Pharmacology and Pathology) and Shabnam Shalapour (Assistant Professor of Pharmacology), have shown that chronic inflammation and fibrosis in humans and mice with non-alcoholic fatty liver disease is accompanied by accumulation of liver-resident immunoglobulin-A-producing (IgA+) cells.. Dr. Michael Karin indciated that This study provides one of the strongest and most direct demonstrations that adaptive immunity actively prevents liver cancer.. The researchers found that NASH-associated mutations provoke the immune system, including cytotoxic T cells, to recognize and attack the newly emerging cancer cells. However, chronic liver inflammation ...
Hepatitis A virus (HAV) replicates in the liver, and is excreted from the body in feces. However, the mechanisms of HAV transport from hepatocytes to the gastrointestinal tract are poorly understood, mainly due to lack of suitable in vitro models. Here, we use a polarized hepatic cell line and in vivo models to demonstrate vectorial transport of HAV from hepatocytes into bile via the apical cell membrane. Although this transport is specific for HAV, the rate of fecal excretion in inefficient, accounting for less than 1% of input virus from the bloodstream per hour. However, we also found that the rate of HAV excretion was enhanced in the presence of HAV-specific IgA. Using mice lacking the polymeric IgA receptor (pIgR(-/-)), we show that a proportion of HAV:IgA complexes are transported via the pIgR demonstrating a role for specific antibody in pathogen excretion.

Viral proteins are highly antigenic and referred to as potent stimulators of adaptive immune responses. useful tool for the investigation of mucosal immune responses or autoimmune diseases and extends the spectrum of antibodies with specific effector functions. by hybridoma technology occur in a polymeric or dimeric form analogue to produced IgA [4]. The obtained secretory IgA antibodies were used for experimental studies of mucosal surfaces and microfold (M) cells in order to investigate bacterial and viral intestine infections. Additional investigations showed that secretory IgAs appear to have got an increased functional stability and activity than IgG counterparts [5]. For their particular effector features, IgA antibodies are of high scientific interest because they are impressive in recruiting polymorphonuclear cells for antibody reliant mobile cytotoxicity (ADCC) [6] and in improving respiratory system burst and phagocytosis of individual leukocytes [7]. These data reveal that antibodies ...
The intestinal mucosa is constantly exposed to microbial and dietary antigens, all of which are considered to induce IgA-secreting plasma cells. Thus, the limited IgA repertoire diversity predicted in previous studies (Dunn-Walters et al., 1997, 2000; Holtmeier et al., 2000; Stoel et al., 2005; Yuvaraj et al., 2009) is difficult to reconcile with the broad range of intestinal antigens. In this study, we show that in fact each individual harbors a private polyclonal and highly diverse IgA repertoire. Because we analyzed switched Ig sequences, repertoire analyses performed in this study did not require sorting of plasma cells. Instead, RNA was isolated directly from intestinal tissue, and IgA-encoding transcripts were enriched during reverse transcription. This approach was equivalent to our results obtained when RNA was isolated out of sorted plasma cells. The IgA repertoire showed characteristics reminiscent of the T cell receptor repertoire of CD8+ memory cells (Naumov et al., 2003), i.e., the ...

IgA has two subclasses - IgA1 and IgA2, the latter lacks a specific amino acid sequence comprising the hinge region. The absence of this region confers more resistance to bacterial degradation. The majority of IgA in humans (95%) is monomeric, produced by plasma cells and freely circulates in the bloodstream. The remainder is produced by mucosal lymphoid cells and secreted in a dimeric form. The half-life is usually 4-5 days, with IgA molecules undergoing rapid hepatic metabolism ...
Background Infection with group A Streptococcus (GAS) can cause severe systemic and locally invasive disease. Invasive group A streptococcal (iGAS) disease incidence varies both seasonally and year-to-year, and it may exhibit clustered outbreaks. We observed an upswing in iGAS cases at a tertiary care Childrens Hospital, prompting further characterization of local iGAS disease. Methods Cases of iGAS disease were abstracted from the medical record by manual chart review of all positive screening tests and cultures for GAS over a 4-year span. Incidence rates per 1000 hospital admissions and per 100 positive GAS tests were calculated and compared. Selected isolates were further characterized by whole-genome sequencing. Results Significant year-to-year differences in per-admission iGAS incidence rate were observed in February and June, although per-positive test incidence rates were not significantly different. Whole-genome sequencing revealed 2 dominant serotypes-emm3 and emm6-with high rates of ...
