Passive protection effect of chicken egg yolk immunoglobulins on enterovirus 71 infected mice. Jenn-Fa Liou, Chih-Wei Chang, Jui-jane Tailiu, Chun-Keung Yu, Huan-Yao Lei, Lih-Ren Chen, and Chein Tai. The objective of this study is to evaluate the passive protective efficiency of immunoglobulin in yolk (IgY) specific against human enterovirus type 71 (EV71). The antibody was raised by intramuscular immunization to 10 White Leghorn hens, with inactivated human EV71 as antigen. The titer and specificity of the antibody were analyzed from purified IgY in the egg yolks of immunized hens. Results indicated that the titer of IgY specific against EV71 increased from the third week after the first immunization. The results of the neutralization effect of specific IgY in EV71-challenged mice demonstrated that the EV71-specific IgY, either by intraperitoneal injection or oral administration, was able to significantly reduce the morbidity and mortality in EV71 infected mice pups.. ...

摘要The malignant Hodgkin/Reed-Sternberg (HRS) cells of Hodgkin lymphoma (HL) are believed to derive from germinal center (GC) B cells, but lack expression of a functional B cell receptor. As apoptosis is the normal fate of B-cell receptor negative GC B cells, mechanisms that abrogate apoptosis are thus critical in HL development, such as epigenetic disruption of certain pro-apoptotic cancer genes including tumor suppressor genes. Identifying methylated genes elucidates oncogenic mechanisms and provides valuable biomarkers; therefore, we performed a chemical epigenetic screening for methylated genes in HI. through pharmacological demethylation and expression profiling. IGST4/CADM1/TSLC1, a pro-apoptotic cell adhesion molecule of the immunoglobulin superfamily, was identified together with other methylated targets. In contrast to its expression in normal GC B cells, IGSF4 was down-regulated and methylated in cell lines, most primary HL, and microdissected HRS cells of 3/5 cases, but not in ...

TY - JOUR. T1 - Regulation of immunoglobulin production in pokeweed mitogen-stimulated cultures of lymphocytes from young and old adults. AU - Ceuppens, J. L.. AU - Goodwin, James. PY - 1982. Y1 - 1982. N2 - Polyclonal (pokeweed mitogen-stimulated) humoral immune responses were studied in cultures of peripheral blood mononuclear cells (PBMC) or T + B cell combinations of young (20 to 40 yr) and aged (,65 yr) individuals. Immunoglobulin (Ig) production was measured in the culture supernatants with an ELISA method. Cultures of lymphocytes from old and young individuals produced similar amounts of IgG and IgM. In co-culture experiments of old or young B cells with old or young T cells, the old T cells consistently provided more help for old and young B cells than the young T cells did. In addition, isolated OKT4(+) cells of old people provided more help than OKT4(+) cells of young people, whereas the suppressor activity of isolated OKT8(+) cells from old people was diminished. Because young or old ...
Clinical measurements were obtained for Ramfjords six teeth (16, 21, 24, 36, 41, and 44 in the FDI two-digit notation system) in all subjects). The deepest probing depth (DPD), mean probing depth (PD), bleeding on probing (BOP), and OLeary plaque control record (PCR) were recorded. When one of the selected teeth was missing from the oral cavity, data were obtained from an adjacent tooth in the same area of the jaw. Two weeks after the first clinical measurement, all participants received full-mouth scaling and root planning, followed by professional mechanical tooth cleaning (PMTC). All procedures were performed by two trained periodontists. After that, the subjects in the test (IgY-GP) group took tablets containing anti-gingipain egg yolk antibodies (100 mg/tablet), without chewing, three times a day after a meal or brushing. Tablets stayed in the mouth for 3 to 5 minutes. Eight hours after two minutes mouth rinse with egg yolk immunoglobulin, active antibodies detected in the saliva from 18 ...

Immunoglobulins play an essential role in the bodys immune system. They attach to foreign substances, such as bacteria, and assist in destroying them. Immunoglobulin is abbreviated Ig. The classes of immunoglobulins are termed immunoglobulin A (IgA), immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin D (IgD) and immunoglobulin E (IgE). ...
Regulated emigration of blood-borne leukocytes plays a defining role in lymphoid organ development, immune surveillance, and inflammatory responses. We report here that mice deficient in the homeobox gene Nkx2-3, expressed in developing visceral mesoderm, show a complex intestinal malabsorption phenotype and striking abnormalities of gut-associated lymphoid tissue and spleen suggestive of deranged leukocyte homing. Mutant Peyers patches were reduced in number and size, intestinal villi contained few IgA(+) plasma cells, and mutant spleens were small and often atrophic, showing fused periarterial lymphoid sheaths, partially merged T and B cell zones, an absent marginal zone, and a dearth of macrophages in red pulp. Semiquantitative RT-PCR analysis and immunohistochemistry revealed down-regulation of mucosal addressin cell adhesion molecule-1 (MAdCAM-1) in endothelial cells in which Nkx2-3 is normally expressed. MAdCAM-1 is a member of the immunoglobulin superfamily, acting as an endothelial cell ...
Description: The alpha(4) integrin, alpha(4)beta(7), plays an important role in recruiting circulating lymphocytes to the gastrointestinal tract, where its ligand mucosal addressin cell adhesion molecule-1 (MAdCAM-1) is preferentially expressed on high endothelial venules (HEVs). Dual antagonists of alpha(4)beta(1) and alpha(4)beta(7), N-(2,6-dichlorobenzoyl)-(L)-4-(2,6-bis-methoxyphenyl)phenylalanine (TR14035) and N-(N-[(3,5-dichlorobenzene)sulfonyl]-2-(R)-methylpropyl)-(D)-phenylalanine (compound 1), were tested for their ability to block the binding of alpha(4)beta(7)-expressing cells to soluble ligand in suspension and under in vitro and in vivo shear flow. Compound 1 and TR14035 blocked the binding of human alpha(4)beta(7) to an (125)I-MAdCAM-Ig fusion protein with IC(50) values of 2.93 and 0.75 nM, respectively. Both compounds inhibited binding of soluble ligands to alpha(4)beta(1) or alpha(4)beta(7) on cells of human or rodent origin with similar potency. Under shear flow in vitro, ...

Kakunaga S., Ikeda W., Itoh S., Deguchi-Tawarada M., Ohtsuka T., Mizoguchi A., Takai Y.. Nectins are Ca2+-independent immunoglobulin-like cell-cell adhesion molecules and comprise a family of four members. At the mossy fiber terminals of hippocampus, nectin-1 and nectin-3 localize at the presynaptic and postsynaptic sides of synaptic junctions, respectively, and their trans-interactions play a role in formation of synapses in cooperation with N-cadherin. Nectins are associated with the actin cytoskeleton through afadin, a nectin- and actin-filament-binding protein. Five nectin-like molecules (Necls) which have domain structures similar to those of nectins have been identified and here we characterize Necl-1/TSLL1/SynCAM3, from now on referred to as Necl-1. Tissue distribution analysis showed that Necl-1 was specifically expressed in the neural tissue. Immunofluorescence and immunoelectron microscopy revealed that Necl-1 localized at the contact sites among axons, their terminals, and glia cell ...
Regulatory T cells (Tregs) are characterized by their role in maintaining peripheral self-tolerance and immune homeostasis. One such role is regulation of the humoral response, which is most clearly demonstrated by abundant auto-antibody production in Scurfin mice and IPEX patients, both of which lack functional Tregs. Indirect Treg regulation of the humoral response via their influence on helper T cells, in particular in germinal centers, is well established. Prior demonstration of direct Treg inhibition of B cells has also been demonstrated, primarily in mice, but is mostly attributable to Treg killing of B cells. This regulation may be especially relevant in B cell-mediated diseases, such as systemic lupus erythematosus (SLE). SLE is an extremely heterogeneous, autoimmune disease characterized in part by high titers of autoantibodies. We hypothesize SLE Tregs are deficient in their ability to suppress immunoglobulin secretion by B cells relative to Tregs isolated from healthy donors. We ...

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 ...
Perturbations in synaptic function could affect the normal behavior of an animal, making it important to understand the regulatory mechanisms of synaptic signaling. Previous work has shown that in Caenorhabditis elegans an immunoglobulin superfamily protein, RIG-3, functions in presynaptic neurons to maintain normal acetylcholine receptor levels at the neuromuscular junction (NMJ). In this study, we elucidate the molecular and functional mechanism of RIG-3. We demonstrate by genetic and BiFC (Bi-molecular Fluorescence Complementation) assays that presynaptic RIG-3 functions by directly interacting with the immunoglobulin domain of the nonconventional Wnt receptor, ROR receptor tyrosine kinase (RTK), CAM-1, which functions in postsynaptic body-wall muscles ...

The relative contributions of humoral and cellmediated immune mechanisms in the rejection of renal homotransplants is an important but still unresolved issue. The diversity of the clinical and pathological pictures in different patients suggests that more than one mechanism may be operating at various times. This study determined serum immunoglobulin levels and complement activity in a series of renal transplant patients and attempted to assess the humoral contribution to rejection. Serial serum samples were obtained from 11 patients receiving renal homografts. Eight patients had clinically apparent episodes of rejection in the first week after surgery, and 3 of these had ...
Immunoglobulins are glycoproteins in the immunoglobulin superfamily that function as antibodies. The terms antibody and immunoglobulin are often used interchangeably. They are found in the blood and tissue fluids, as well as many secretions. In structure, they are large Y-shaped globular proteins. In mammals there are five types of antibody: IgA, IgD, IgE, IgG, and IgM. Each immunoglobulin class differs in its biological properties and has evolved to deal with different antigens.[12] Antibodies are synthesized and secreted by plasma cells that are derived from the B cells of the immune system. An antibody is used by the acquired immune system to identify and neutralize foreign objects like bacteria and viruses. Each antibody recognizes a specific antigen unique to its target. By binding their specific antigens, antibodies can cause agglutination and precipitation of antibody-antigen products, prime for phagocytosis by macrophages and other cells, block viral receptors, and stimulate other immune ...
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.

Cell adhesion molecule (CADM) genes encode immunoglobulin superfamily molecules, which are involved in cell‑cell adhesion in a number of human epithelia. Through the maintenance of epithelia, CADM genes protect against malignant conversion and metastasis. Whilst numerous in vitro studies have investigated the molecular characteristics of CADM1 and CADM4 and in vivo studies have investigated CADM1 and CADM4 expression in a number of tumor types, the roles of CADM1 and CADM4 have yet to be elucidated. Therefore, in the present study, CADM1 and CADM4 expression levels were evaluated using immunohistochemistry staining in 208 patients with breast cancer and compared with clinicopathological factors. CADM1 and CADM4 expression levels were negative in 160 (76.9%) and 166 (79.8%) of the 208 cases, respectively. The lack of expression in these cases was associated with advanced tumor stage, suggesting that inactivation of CADM1 and CADM4 promotes breast cancer development. The prognostic role of CADM1 ...

Junctional adhesion molecule-C (JAM-C) is an adhesion molecule involved in transendothelial migration of leukocytes. In this study, we examined JAM-C expression in the synovium and investigated the role of this molecule in two experimental mouse models of arthritis. JAM-C expression was investigated by reverse transcriptase-polymerase chain reaction and immunohistochemistry. The effects of a monoclonal anti-JAM-C antibody were assessed in antigen-induced arthritis (AIA) and K/BxN serum transfer-induced arthritis. JAM-C was expressed by synovial fibroblasts in the lining layer and associated with vessels in the sublining layer in human and mouse arthritic synovial tissue. In human tissue, JAM-C expression was increased in rheumatoid arthritis (RA) as compared to osteoarthritis synovial samples (12.7 ± 1.3 arbitrary units in RA versus 3.3 ± 1.1 in OA; p | 0.05). Treatment of mice with a monoclonal anti-JAM-C antibody decreased the severity of AIA. Neutrophil infiltration into inflamed joints was
Synaptic cell adhesion molecules (SynCAMs) are crucial for synapse formation and plasticity. However, we have previously demonstrated that SynCAMs are also required during earlier stages of neural circuit formation because SynCAM1 and SynCAM2 (also known as CADM1 and CADM2, respectively) are important for the guidance of post-crossing commissural axons. In contrast to the exclusively homophilic cis-interactions reported by previous studies, our previous in vivo results suggested the existence of heterophilic cis-interactions between SynCAM1 and SynCAM2. Indeed, as we show here, the presence of homophilic and heterophilic cis-interactions modulates the interaction of SynCAMs with trans-binding partners, as observed previously for other immunoglobulin superfamily cell adhesion molecules. These in vitro findings are in agreement with results from in vivo studies, which demonstrate a role for SynCAMs in the formation of sensory neural circuits in the chicken embryo. In the absence of SynCAMs, ...
TY - JOUR. T1 - The role of B cell proliferation in the generation of immunoglobulin-secreting cells in man. AU - Jelinek, Diane F. AU - Lipsky, P. E.. PY - 1983. Y1 - 1983. N2 - The relationship of B cell proliferation and the generation of immunoglobulin-secreting cells (ISC) was explored in vitro by examining the effect of hydroxyurea (HU), an inhibitor of cellular DNA synthesis, on the generation of ISC from human peripheral blood mononuclear cells (PBM). HU completely inhibited the capacity of PBM to generate ISC in response to pokeweed mitogen (PWM) and other polyclonal B cell activators. Inhibition resulted from an effect on B cell proliferation, because HU also prevented the generation of ISC in cultures of purified B cells supplemented with either T cell supernatants or mitomycin C-treated T cells. Inhibiting B cell proliferation by treating them with mitomycin C before culture also abolished the generation of ISC. When ISC were enumerated after a 7-day incubation with PWM, the addition ...
TY - JOUR. T1 - Calorie restriction modulates Th-1 and Th-2 cytokine-induced immunoglobulin secretion in young and old C57BL/6 cultured submandibular glands. AU - Jolly, C. A.. AU - Fernandez, R.. AU - Muthukumar, A. R.. AU - Fernandes, G.. PY - 1999/12/1. Y1 - 1999/12/1. N2 - Immunoglobulin production by the salivary gland plays an important role in oral and upper respiratory tract immunity. Age and/or disease may compromise salivary gland function. In order to gain insight into the role of calorie restriction (CR) on immunoglobulin (Ig) production, we determined the effect of ad libitum (AL) feeding and CR in young (3 months) and old (18-24 months) C57BL/6 mouse submandibular glands (SM). The SM tissues were fragmented and cultured in the absence (control) or presence of either Th-1 cytokines, such as interleukin-2 (IL-2) and interferon-γ (IFN-γ), or Th-2 cytokines, e.g. IL-4 and IL-5, for seven days. Culture supernatants were then analyzed for immunoglobulin A (IgA), IgM, and IgG(2α) ...
|jats:p| The junctional adhesion molecules (JAMs) have been recently described as interendothelial junctional molecules and as integrin ligands. Here we show that JAM-B and JAM-C undergo heterophilic interaction in cell-cell contacts and that JAM-C is recruited and stabilized in junctional complexes by JAM-B. In addition, soluble JAM-B dissociates soluble JAM-C homodimers to form JAM-B/JAM-C heterodimers. This suggests that the affinity of JAM-C monomers to form dimers is higher for JAM-B than for JAM-C. Using antibodies against JAM-C, the formation of JAM-B/JAM-C heterodimers can be abolished. This liberates JAM-C from its vascular binding partner JAM-B and makes it available on the apical side of vessels for interaction with its leukocyte counterreceptor α|jats:sub|M|/jats:sub|β|jats:sub|2|/jats:sub| integrin. We demonstrate that the modulation of JAM-C localization in junctional complexes is a new regulatory mechanism for α|jats:sub|M|/jats:sub|β|jats:sub|2|/jats:sub|-dependent adhesion of
Immunoglobulins are made by white blood cells known as B cells (B lymphocytes). Any disease that harms the development or function of B cells will, therefore, affect the production of immunoglobulin antibodies. T cells, another type of white blood cell, may also be involved in immunodeficiency disorders. About 70 percent of immunoglobulin deficiencies involve B lymphocytes and 20-30 percent involve T lymphocytes. Another 10 percent may involve both B and T lymphocytes. Many of the infections that occur in children with immunoglobulin deficiency syndromes are caused by bacterial organisms or microbes. Certain of these invasive organisms form capsules when they enter the body, a mechanism used to confuse the immune system. In a healthy body with an adequately functioning immune system, immunoglobulin antibodies bind to the capsule and overcome the bacterias defenses. Streptococci, meningococci, and Haemophilus influenzae , organisms that cause diseases such as otitis media , sinusitis , pneumonia ...
Entyvio, an integrin receptor antagonist, is a humanized monoclonal antibody that specifically binds to the alpha4beta7 integrin and blocks the interaction of alpha4beta7 integrin with mucosal addressin cell adhesion molecule-1 (MAdCAM-1) and inhibits the migration of memory T-lymphocytes across the endothelium into inflamed gastrointestinal parenchymal tissue. Entyvio does not bind to or inhibit function of the alpha4beta1 and alpha E beta 7 integrins and does not antagonize the interaction of alpha4 integrins with vascular cell adhesion molecule-1 (VCAM-1). The alpha4beta7 integrin is expressed on the surface of a discrete subset of memory T-lymphocytes that preferentially migrate into the gastrointestinal tract. MAdCAM-1 is mainly expressed on gut endothelial cells and plays a critical role in the homing of T-lymphocytes to gut lymph tissue. The interaction of the alpha4beta7 integrin with MAdCAM-1 has been implicated as an important contributor to the chronic inflammation that is a hallmark ...

Natalizumab is a selective adhesion-molecule inhibitor and binds to the alpha4-subunit of human integrins, which is highly expressed on the surface of all leukocytes, with the exception of neutrophils. Specifically, natalizumab binds to the alpha4beta1 integrin, blocking the interaction with its cognate receptor, vascular cell adhesion molecule-1 (VCAM-1), and ligands osteopontin, and an alternatively spliced domain of fibronectin, connecting segment-1 (CS-1). Natalizumab blocks the interaction of alpha4beta7 integrin with the mucosal addressin cell adhesion molecule-1 (MadCAM-1). Disruption of these molecular interactions prevents transmigration of mononuclear leukocytes across the endothelium into inflamed parenchymal tissue. A further mechanism of action of natalizumab may be to suppress ongoing inflammatory reactions in diseased tissues by inhibiting the interaction of alpha4-expressing leukocytes with their ligands in the extracellular matrix and on parenchymal cells. As such, natalizumab ...
An investigation was conducted to determine whether there is a possible relationship between the X-ray changes, the number of asbestos (1332214) bodies and the level of serum immunoglobulins in a group of 52 asbestos workers. The workers were divided into three groups: group-1 was directly exposed to asbestos, with radiographic changes suggesting asbestosis; group-2 was directly exposed to asbesto

Egg yolk immunoglobulins (IgY) are considered as a promising tool of establishing passive immunity against enteric pathogens (e.g. Salmonella) in poultry (Kovacs-Nolan and Mine, 2005). In our previous works, in-feed incorporation of freeze-dried yolk powder (FYP) improved performances of Salmonella-infected broilers (Marcq et al., 2009). Nevertheless, no extra value could be attributed to the presence of specific IgY when a comparison was done between impact of hyperimmune or non immune FYP both concerning growth performances and Salmonella infection. We hypothesized that these inconclusive in vivo results were related to the sensitivity of IgY to gastrointestinal conditions. Egg yolks with ...
Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses ...

Infections post-transplant are common, but it is difficult to predict which patients are most at risk. Hypogammaglobulinemia is a known risk factor for infection. In this prospective, single-center observational study, low immunoglobulin levels were common post-transplant, and correlated with an increased risk of infection. This study raises the question of whether such monitoring should become routine practice, and whether giving immunoglobulin replacement to patients with demonstrated low levels would reduce infection rates.. ...
Plasma membranes from pig mesenteric lymph-node lymphocytes contain a large number of polypeptide chains ranging in molecular weight from 20,000 to greater than 470,000, with a major component of 46,000. There are approx. 12-15 glycoproteins. The membranes contain immunoglobulin G, which comprises 0.6% of the total protein. Immunoglobulin M is also detected, but has not been accurately quantified for technical reasons. Possible origins of the membrane-associated immunoglobulin are briefly discussed. It is concluded that the immunoglobulin is probably associated with the plasma membrane in the intact cell.. ...
Every cell that lies within the kidney glomerulus is affected by diabetes, and every cell that lies within the kidney glomerulus is affected by the actions of its neighbors. In the current study, we unearthed a signaling cascade that regulates expression of the adhesion molecule VCAM-1 by GECs. Specifically, ligand binding by the receptor CCR2 expressed by GECs induces VCAM-1 upregulation through a pathway that is regulated by the MSK1/2-dependent phosphorylation of H3Ser10. Heightened phospho-histone H3Ser10 levels in experimental and human diabetic kidney disease and recent improvements in MSK1/2 inhibitor specificity (19) should galvanize efforts to explore the modulation of histone phosphorylation as a means of attenuating kidney disease in diabetes.. As a marker of endothelial activation, we focused on the regulation of expression of VCAM-1, an immunoglobulin superfamily member that is expressed on the surface of endothelial cells in response to proinflammatory cytokines. VCAM-1 promotes ...

Constant region of immunoglobulin heavy chains. Immunoglobulins, also known as antibodies, are membrane-bound or secreted glycoproteins produced by B lymphocytes. In the recognition phase of humoral immunity, the membrane-bound immunoglobulins serve as receptors which, upon binding of a specific antigen, trigger the clonal expansion and differentiation of B lymphocytes into immunoglobulins-secreting plasma cells. Secreted immunoglobulins mediate the effector phase of humoral immunity, which results in the elimination of bound antigens (PubMed:22158414, PubMed:20176268). The antigen binding site is formed by the variable domain of one heavy chain, together with that of its associated light chain. Thus, each immunoglobulin has two antigen binding sites with remarkable affinity for a particular antigen. The variable domains are assembled by a process called V-(D)-J rearrangement and can then be subjected to somatic hypermutations which, after exposure to antigen and selection, allow affinity maturation for

Immunoglobulin Therapy can help people with weakened immune systems or other diseases fight off infections. Intravenous immunoglobulin
Antigen processing and presentation and cytotoxic targeting depend on the activities of several lysosomal enzymes that require mannose 6-phosphate (M6P) sorting signals for efficient intracellular transport and localization. In this paper, we show that mice deficient in the formation of M6P residues exhibit significant loss of cathepsin proteases in B cells, leading to lysosomal dysfunction with accumulation of storage material, impaired antigen processing and presentation, and subsequent defects in B cell maturation and antibody production. The targeting of lysosomal and granular enzymes lacking M6P residues is less affected in dendritic cells and T cells and sufficient for maintenance of degradative and lytic functions. M6P deficiency also impairs serum immunoglobulin levels and antibody responses to vaccination in patients. Our data demonstrate the critical role of M6P-dependent transport routes for B cell functions in vivo and humoral immunity in mice and human ...

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

The overall aim of the study was to determine the passive prophylatic effect of bovine milk immunoglobulin administered orally either as a bolus (once a day) or as continuously (three times a day) against diarrhoea caused by Escherichia coli K 88. As the piglets have gastrointestinal structural and physiological similarities to humans they were assumed to be an appropriate model for the study. The first part of the study was done to evaluate the quantity of undigested immunoglobulin G in the gastrointestinal tract of the piglet. This was conducted in two experiments. One was a pilot study and the other was to estimate the quantity of undigested immunoglobulin G in the gut. A pilot study was conducted to evaluate the rate of movement and the quantities of digesta that can be collected in the gastrointestinal tract regions at varying time intervals. Ten piglets were randomly divided into five groups of two in each. One from each group was selected, fed with an experimental diet which contained ...
My laboratory studies two aspects of lymphocyte development and diversification. The production of a diverse repertoire of immunoglobulin molecules is of paramount importance to the maintenance of a functional immune system. One project in my laboratory focuses on B cell development and mechanisms of generation of immunoglobulin diversity in cattle. Unlike mouse and human, species that generate diversity by the rearrangement of numerous gene segments, cattle appear to use a recombinational mechanism known as gene conversion to generate a diverse repertoire of immunoglobulin molecules. In addition to this novel mechanism of generating diversity, B cell development in cattle appears to differ from that observed in mouse and human; B cell development occurs in the ileal Payers patch, a specialized lymphoid organ, rather than in the bone marrow. Experiments designed to elucidate the exact mechanisms of diversification and processes that regulate B cell development are ongoing. Another area of ...

Carcinostatic products are formed by coupling, by covalent bonding, the A chain of ricin with an antibody which is capable of selectively recognizing a given antigen at the surface of cancerous cells. Such products can be made by the formation of a disulphide bridge between the free thiol group in the A chain of ricin and an immunoglobulin or immunoglobulin fragment into which a thiol group or an activated disulphide group has been introduced. The A chain of ricin and the immunoglobulin are carefully purified before use.
