RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Removal of non-specific serum inhibitors of haemagglutination of rubella virus by treatment with dodecylamine-gel. (1/5906)

The suitability of using dodecylamine-gel for removing the serum non-antibody-like inhibitors of haemagglutination by rubella was studied. Compared with kaolin and MnCl2/heparin treatment this new procedure appears to have a higher specificity since it removes the non-antibody-like inhibitors from serum without affecting the immunoglobulin level significantly. The potential application of this procedure in routine serological analysis for rubella virus infection is discussed.  (+info)

Staphylococcal protein A; its preparation and an application to rubella serology. (2/5906)

Good yields of staphylococcal protein A are obtained by growing the staphylococcus Cowan type 1 on cellophane agar. The activity of these preparations in removing immunoglobulin G (IgG) from human serum can be readily measured by the Mancini radial-diffusion technique and the correct in-use dilution determined. Treatment with protein A of sera from women with a history of rubella may help in the identification of those having specific antibody in the IgM and IgA fractions. This relatively simple procedure may have worthwhile application in the diagnosis of rubella.  (+info)

Cloning and functional studies of a novel gene aberrantly expressed in RB-deficient embryos. (3/5906)

The tumor suppressor RB regulates diverse cellular processes such as G1/S transition, cell differentiation, and cell survival. Indeed, Rb-knockout mice exhibit phenotypes including ectopic mitosis, defective differentiation, and extensive apoptosis in the neurons. Using differential display, a novel gene, Rig-1, was isolated based on its elevated expression in the hindbrain and spinal cord of Rb-knockout embryos. The longest open reading frame of Rig-1 encoded a polypeptide that consists of a putative extracellular segment with five immunoglobulin-like domains and three fibronectin III-like domains, a putative transmembrane domain, and a distinct intracellular segment. The Rig-1 sequence was 40% identical to the recently identified roundabout protein. Consistent with the predicted transmembrane nature of the protein, Rig-1 protein was present in the membranous fraction. Antisera raised against the putative extracellular and intracellular segments of Rig-1 reacted with an approximately 210-kDa protein in mouse embryonic CNS. Rig-1 mRNA was transiently expressed in the embryonic hindbrain and spinal cord. Elevated levels of Rig-1 mRNA and protein were found in Rb-/- embryos. Ectopic expression of a transmembrane form of Rig-1, but not the secreted form, promoted neuronal cell entrance to S phase and repressed the expression of a marker of differentiated neuron, Talpha1 tubulin. Thus Rig-1, a possible distant relative of roundabout, may mediate some of the pleiotropic roles of RB in the developing neurons.  (+info)

NKp44, a triggering receptor involved in tumor cell lysis by activated human natural killer cells, is a novel member of the immunoglobulin superfamily. (4/5906)

Surface receptors involved in natural killer (NK) cell triggering during the process of tumor cell lysis have recently been identified. Of these receptors, NKp44 is selectively expressed by IL-2- activated NK cells and may contribute to the increased efficiency of activated NK cells to mediate tumor cell lysis. Here we describe the molecular cloning of NKp44. Analysis of the cloned cDNA indicated that NKp44 is a novel transmembrane glycoprotein belonging to the Immunoglobulin superfamily characterized by a single extracellular V-type domain. The charged amino acid lysine in the transmembrane region may be involved in the association of NKp44 with the signal transducing molecule killer activating receptor-associated polypeptide (KARAP)/DAP12. These molecules were found to be crucial for the surface expression of NKp44. In agreement with data of NKp44 surface expression, the NKp44 transcripts were strictly confined to activated NK cells and to a minor subset of TCR-gamma/delta+ T lymphocytes. Unlike genes coding for other receptors involved in NK cell triggering or inhibition, the NKp44 gene is on human chromosome 6.  (+info)

Detection of antibody to bovine syncytial virus and respiratory syncytial virus in bovine fetal serum. (5/5906)

Batches of commercial fetal bovine serum, described by the suppliers as antibody-free, all contained antibody to bovine syncytial virus (BSV) when tested by indirect immunofluorescence. Antibody to bovine respiratory syncytial virus (RSV) was not detected in these sera. Twenty-four percent of individual fetal bovine sera contained antibody to BSV, and 14% contained antibody to RSV when tested by indirect immunofluorescence. BSV antibody titers in fetal sera from dams with high BSV antibody levels were variable but always higher than RSV antibody titers. Radial immunodiffusion studies with BSV-positive sera revealed the presence of immunoglobulin M (IgM), IgG, and IgA, but the quantity of these immunoglobulins was not directly related to the BSV antibody titers. The evidence suggests that the antibody present in fetal sera arose as the result of infection rather than from maternal transfer across the placenta.  (+info)

Detection of small numbers of immature cells in the blood of healthy subjects. (6/5906)

AIMS: To determine the frequency of immature haemopoietic cells in the peripheral blood of healthy persons. METHODS: Cytocentrifuge preparations were made using mononuclear leucocytes separated by a Ficoll-Hypaque density gradient. The slides were stained by May-Grunwald-Giemsa. The combination with immunoperoxidase technique allowed immunotyping of uncommon blood cells. RESULTS: Blast cells expressing the progenitor cell marker CD34 represented 0.11 (0.06) per cent (mean (SD)) of the total mononuclear leucocyte count; these were the haemopoietic progenitor cells in the peripheral blood. Dark blue cells expressing CD38, CD45, HLA-DR, CD4, CD11a, CD29, CD49d, CD50, and CD54 represented 0.30 (0.21) per cent of the mononuclear leucocytes; most of these cells did not express T, B, NK, myelomonocytic, progenitor cell, proliferation, activation, blood dendritic cell, or follicular dendritic cell markers. These were dendritic cell precursors in the peripheral blood. Very small numbers of cells expressing CD83 were found. Blast-like cells expressing CD45, HLA-DR, CD11a, and CD50 represented 0.15 (0.10) per cent of the mononuclear leucocytes; morphology and immunotyping supported the conclusion that these cells were poorly differentiated monocytes. CONCLUSIONS: Morphological investigation of mononuclear leucocytes in peripheral blood of healthy persons can be used to detect small numbers of blasts, dark blue cells, and blast-like cells. The immunoperoxidase technique can then be used for immunotyping of these cells. This simple method may be helpful in diagnosing haematological disorders.  (+info)

Characterization of a novel rat brain glycosylphosphatidylinositol-anchored protein (Kilon), a member of the IgLON cell adhesion molecule family. (7/5906)

In the central nervous system, many cell adhesion molecules are known to participate in the establishment and remodeling of the neural circuit. Some of the cell adhesion molecules are known to be anchored to the membrane by the glycosylphosphatidylinositol (GPI) inserted to their C termini, and many GPI-anchored proteins are known to be localized in a Triton-insoluble membrane fraction of low density or so-called "raft." In this study, we surveyed the GPI-anchored proteins in the Triton-insoluble low density fraction from 2-week-old rat brain by solubilization with phosphatidylinositol-specific phospholipase C. By Western blotting and partial peptide sequencing after the deglycosylation with peptide N-glycosidase F, the presence of Thy-1, F3/contactin, and T-cadherin was shown. In addition, one of the major proteins, having an apparent molecular mass of 36 kDa after the peptide N-glycosidase F digestion, was found to be a novel protein. The result of cDNA cloning showed that the protein is an immunoglobulin superfamily member with three C2 domains and has six putative glycosylation sites. Since this protein shows high sequence similarity to IgLON family members including LAMP, OBCAM, neurotrimin, CEPU-1, AvGP50, and GP55, we termed this protein Kilon (a kindred of IgLON). Kilon-specific monoclonal antibodies were produced, and Western blotting analysis showed that expression of Kilon is restricted to brain, and Kilon has an apparent molecular mass of 46 kDa in SDS-polyacrylamide gel electrophoresis in its expressed form. In brain, the expression of Kilon is already detected in E16 stage, and its level gradually increases during development. Kilon immunostaining was observed in the cerebral cortex and hippocampus, in which the strongly stained puncta were observed on dendrites and soma of pyramidal neurons.  (+info)

Characterization of an immunoglobin cDNA clone containing the variable and constant regions for the MOPC 21 kappa light chain. (8/5906)

Nucleotide sequence analysis and restriction endonuclease mapping have been used to characterize a cDNA copy of immunoglobulin MOPC 21 Kappa mRNA clones in the bacterial plasmid pMB9. Three regions of the inserted cDNA of plasmid pL21-1 have been sequenced and match the known protein sequence at amino acid residues 1-24, 128-138 and 171-179. With these sequences to provide absolute correlations between the restriction map and the structural gene sequence it has been possible to exactly deduce the positions of all 11 of the insert restriction sites mapped within the structural gene. The pL21-1 insert contains the complete variable and constant regions as well as parts of the 3' untranslated and polypeptide leader coding sequences.  (+info)

Class I-restricted T cell-associated molecule (Crtam) is an Ig-like cell surface protein that was originally found on activated NKT cells (Kennedy et al., 2000), NK cells, and CD8+ T cells (Arase et al., 2005; Boles et al., 2005; Galibert et al., 2005) and shown to bind the cell adhesion molecule 1 (Cadm1, also known as Nectin like [Necl] 2; Arase et al., 2005; Boles et al., 2005; Galibert et al., 2005). Cadm1 is a cell surface molecule of the nectin and Necl families that is expressed on CD8α DCs (Galibert et al., 2005; Poulin et al., 2010), epithelial cells, neurons, and tumor cells (Sakisaka and Takai, 2004; Mizutani et al., 2011). Crtam-Cadm1 interactions strengthen NK cell and CD8+ T cell effector functions (Arase et al., 2005; Boles et al., 2005; Galibert et al., 2005; Murakami, 2005) and promote the retention of virus-specific CD8+ T cells within LNs (Takeuchi et al., 2009).

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 ...

Examples include igg, igm, iga, IgD and ige. (2) A protein produced by plasma cells and lymphocytes and characteristic of these types of cells. 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 ...

The IgG subclass of immunoglobulins are the major type of immunoglobulin in normal human serum. Each IgG molecule is made up of two heavy chains and two light chains; in turn each light chain is made up of two Ig domains, one variable (V,sub,L,/sub,) domain and one constant (C,sub,L,/sub,) domain, whilst each heavy chain comprises four Ig domains, three constant (C,sub,H1,/sub,, C,sub,H2,/sub,, C,sub,H3,/sub,) domains and a single variable (V,sub,H,/sub,) domain. One V,sub,H,/sub, and one V,sub,L,/sub, domain at the end of each Fab arm together determine antigenic recognition. An example of a IgG1 C,sub,H1,/sub, domain is given below (CATH domain ID 1l6xA02 ...

Mouse IgG and IgA, with reactivity to dinitrophenol conjugated to carrier protein, have been isolated from myeloma proteins by means of a variety of affinity techniques. The IgA was predominantly in the dimeric form. The in vitro and in vivo biological activities of IgA-containing immune complexes were assessed in the rat. IgA-containing immune complexes were demonstrated, in a dose-dependent manner in vitro, to activate neutrophils and to generate O.-2. In addition, these immune complexes showed evidence of complement activation in vitro, by the use of immunofixation techniques. When IgA was instilled into the airways of rats and antigen was injected intravenously, acute lung injury occurred, as reflected by increases in lung permeability and morphological changes consisting of blebbing of endothelial cells, intra-alveolar hemorrhage, and fibrin deposition. The lung changes were directly proportional to the amount of IgA instilled into the airways and failed to occur if intravenous injection of ...
