Lymphocyte activation gene-3 (LAG-3) is an MHC class II ligand structurally and genetically related to CD4. Although its expression is restricted to activated

We show in this study that Tregs functionally inhibit DC activation in an Ag-dependent manner involving the interaction of LAG-3 and its ligand, MHC II. This LAG-3/MHC II molecular interaction provides a novel tolerogenic pathway that may endow Tregs the capacity to enforce tolerance by inhibiting DC function. The ability of Ag-specific Tregs to modulate DC function would potentially allow limited numbers of Ag-specific Tregs to inhibit many potential responding T effectors.. Expression in T cells of LAG-3 lacking its cytoplasmic tail was sufficient to confer regulatory activity, consistent with the notion that reverse signaling through MHC II in DCs, rather than LAG-3 signaling in T cells, was responsible for inhibition of DCs. Furthermore, inhibition of DC maturation required cell contact and bystander DCs were only modestly affected, indicating that release of inhibitory cytokines by regulatory cells were not primarily responsible. Prior studies have shown that LAG-3 engagement inhibits T ...

Plans are well advanced for the 8th Workshop (see www.hlda8.org), to be organized in Adelaide, Australia, in 2004 under the aegis of Prof. H. Zola (Child Health Research Institute, Adelaide, Australia). It is sometimes assumed that the catalog of surface molecules associated with human hemopoietic cells is now essentially complete, but there is abundant evidence in the literature for novel surface molecules that would merit study at the next Workshop, and that could provide the basis for new CD designations. Table III⇓ comprises a list of potential new molecules reported following the production of monoclonal antibodies, and also a more extensive list of surface molecules identified via gene cloning. In most instances, no antibodies are available against the putative new leukocyte/endothelial markers in this latter group. Specific and well characterized reagents, whether monoclonal or polyclonal, are needed not only for detecting these new virtual molecules but also for defining functional ...

T cells are major effector cells of the adaptive immune response from influencing antibody production to maintaining tolerance. The defining marker of the T cell is the T-cell receptor (TCR), and 2 distinct T-cell subsets have been characterized based on the structure of the TCR: TCRα/β and TCRγδ. The specificity of the TCRα/β T-cell repertoire is established during fetal development of the thymus, which develops at week 6 of gestation. Immature thymic cells develop from fetal liver cells and, after birth, from hematopoetic stem cells (HSCS) in the bone marrow. T cells develop from common lymphoid progenitor cells derived from HSCs within the thymus and undergo stages of differentiation, expressing 1 or both of the cytodifferentiation (CD) antigens CD4 and CD8. T cells expressing the α/β TCR are divided into various subsets based on surface CD antigens and function. CD4+ T cells, or helper T cells (TH), make up approximately 70% of T cells in the peripheral blood. TH cells recognize ...

CD248 (endosialin) is a transmembrane glycoprotein that is dynamically expressed on pericytes and fibroblasts during tissue development, tumour neovascularization and inflammation. Its role in tissue remodelling is associated with increased stromal cell proliferation and migration. We show that CD248 is also uniquely expressed by human, but not mouse (C57BL/6), CD8(+) naive T cells. CD248 is found only on CD8(+) CCR7(+) CD11a(low) naive T cells and on CD8 single-positive T cells in the thymus. Transfection of the CD248 negative T-cell line MOLT-4 with CD248 cDNA surprisingly reduced cell proliferation. Knock-down of CD248 on naive CD8 T cells increased cell proliferation. These data demonstrate opposing functions for CD248 on haematopoietic (CD8(+)) versus stromal cells and suggests that CD248 helps to maintain naive CD8(+) human T cells in a quiescent state.

Signaling lymphocytic activation molecule (SLAM)-linked protein (SAP) plays an essential role in the immune Ezatiostat system mediating the function of several members of the SLAM family (SLAMF) of receptors whose expression is essential for T NK and B-cell Rabbit Polyclonal to GABRD. responses. in mouse. However it is definitely less obvious whether other users of this family may also participate in the development of these innate T cells. Here we display that and strain suggesting that Slamf5 may function as a negative regulator of innate CD8+ T cell development. Accordingly B6 mice showed an exclusive growth of innate CD8+ T cells but not NKT cells. Interestingly the SAP-independent strain showed an growth of both splenic innate CD8+ T cells and thymic NKT cells. On the other hand and similar to what was recently demonstrated in BALB/c mice the proportions of thymic promyelocytic leukemia zinc finger (PLZFhi) NKT cells and innate CD8+ T cells significantly improved in the SAP-independent ...

This modification could also explain the Z-DEVD-FMK mouse increased resistance to Az in F. tularensis LVS. In addition, there are methylases that can confer increased resistance by targeted. modification (methylation) of a specific adenine residue of the 23S rRNA. There are some methylases that have been identified as critical virulence factors for Francisella that might carry out this modification [39]. Some methylases that are present in the genome of F. novicida are either absent or are pseudogenes/nonfunctional genes (such as FTT0010, FTT0770, FTT1430, FTT1719, and FTT1735c) in F. tularensis Temsirolimus order Schu S4, potentially contributing to the different sensitivities to Az between the strains [34]. Any potential role of these molecules in Az sensitivity or resistance in Francisella has not yet been determined. It has been suggested that Az attaches to the acidic LPS on the outer membrane of gram-negative bacteria, allowing the drug to penetrate through the outer membrane and enter the ...

1). The same pattern existed among strains producing the other Vsa isotypes. Strains producing short Vsa proteins attached to MLE-12 cells in statistically significant higher numbers than did those strains that produced long proteins. These findings were true for strains producing a short or long VsaA protein, a short or long VsaI protein, and VsaH. There is no long form of the VsaH because this protein lacks tandem repeats (Simmons et al., 1996, 2004). There were no statistical differences observed between the Vsa isotypes examined. The only significant differences. were between strains producing short and long Vsa proteins. The mutants that lack EPS-I that APO866 manufacturer are available all produce a long VsaG protein. The EPS-I mutants CTG1291 and CTG1701 exhibited statistically significant reduced attachment to MLE-12 cells as compared to all strains CT99021 of mycoplasma that produced the polysaccharide (Fig. 2). The complemented mutant that had restored EPS-I production, strain ...

Objectives: Although CD8+T cells play a critical role in the control of HIV-1 infection, their antiviral efficacy can be limited by antigenic variation and immune exhaustion. The latter phenomenon is characterized by the upregulation of multiple inhibitory receptors, such as programmed death-1 (PD-1), CD244 and lymphocyte activation gene-3 (LAG-3), which modulate the functional capabilities of CD8+T cells. Design and methods: Here, we used an array of different human leukocyte antigen (HLA)-B*15 : 03 and HLA-B*42 : 01 tetramers to characterize inhibitory receptor expression as a function of differentiation on HIV-1-specific CD8+T-cell populations (n=128) spanning 11 different epitope targets. Results: Expression levels of PD-1, but not CD244 or LAG-3, varied substantially across epitope specificities both within and between individuals. Differential expression of PD-1 on T-cell receptor (TCR) clonotypes within individual HIV-1-specific CD8+T-cell populations was also apparent, independent of clonal

The immunophenotypic profiles of low-grade B cell NHL are complex and still under investigation. Especially the T cell antigen CD5 is used to subclassify this group of B cell lymphomas. The MALT lymphomas express pan-B-cell antigens but typically lack CD5 expression [2]. CD5 is a T-cell antigen that is expressed on normal B-cells and occasionally on B-cell neoplasm [8]. The T cell antigen CD5 has been reported in B cell NHL between 3% and 40% [9].. Whether CD5 expression is relevant to the prognosis of patients with MALT lymphoma is controversial [5]. In the conjunctival region, we reviewed the cases of three patients with CD5-positive MALT lymphoma (Table 1). The cases of one patients formally reported by Wenzel et al. were presented as a more aggressive disease than typical MALT lymphoma [6]. Local recurrence was noted in this case, and patient had rapid generalization to the contralateral conjunctiva, mediastinal lymph nodes and the esophagogastric. The investigators suggested that CD5 ...

CD26 and CD31 surface antigen expression on human colostral T cells.: The expression levels of CD26 and CD31 surface antigens, two adhesion/activation molecules

Our study addresses the important clinical issue of resistance to CART-19 and establishes a novel combinatorial mechanism by which its cognate epitope could be removed from the cell surface without discarding the target protein entirely. This mechanism involves the clustering of nonsense and missense mutations in exon 2 of CD19. Distributed frameshift mutations would have prevented CD19 protein expression but also left the leukemic cells without the important activator of PI3K and SFTK signaling. In contrast, frameshift mutations clustered in the nonconstitutive exon 2 eliminate full-length CD19, but allow expression of the Δex2 isoform. Not only is this isoform mostly cytosolic and thus hidden from T cells, but expression of its membrane fraction does not trigger killing by CART-19, at least not at physiologic levels. At the same time, it was found to be even more stable than full-length CD19, which could be due to either the presence of a degron within exon 2-encoded amino acid sequence or ...

Leukocyte surface antigen CD53 is a protein that in humans is encoded by the CD53 gene. The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is a cell surface glycoprotein that is known to complex with integrins. It contributes to the transduction of CD2-generated signals in T cells and natural killer cells and has been suggested to play a role in growth regulation. Familial deficiency of this gene has been linked to an immunodeficiency associated with recurrent infectious diseases caused by bacteria, fungi and viruses. Alternative splicing results in multiple transcript variants encoding the same protein. Cluster of differentiation Tetraspanin GRCh38: Ensembl ...

We describe a high-throughput screening system to detect interactions between leucocyte surface proteins, taking into account that these interactions are usually of very low affinity. The method involves producing the extracellular regions of leucocyte proteins with tags so that they can be bound to nanoparticles to provide an avid reagent to screen over an array of 36 similar proteins immobilized using the Proteon XPR36 with detection by surface plasmon resonance. The system was tested using established interactions that could be detected without spurious binding. The ability to detect new interactions was shown by identifying a new interaction between carcinoembryonic antigen-related cell adhesion molecule 1 and carcinoembryonic antigen-related cell adhesion molecule 8.

Background: Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1), an immunoglobulin (Ig)-related glycoprotein, serves as cellular receptor for a variety of Gram-negative bacterial pathogens associated with the human mucosa. In particular, Neisseria gonorrhoeae, N. meningitidis, Moraxella catarrhalis, and Haemophilus influenzae possess well-characterized CEACAM1-binding adhesins. CEACAM1 is typically involved in cell-cell attachment, epithelial differentiation, neovascularisation and regulation of T-cell proliferation, and is one of the few CEACAM family members with homologues in different mammalian lineages. However, it is unknown whether bacterial adhesins of human pathogens can recognize CEACAM1 orthologues from other mammals.,br /,Results: Sequence comparisons of the amino-terminal Ig-variable-like domain of CEACAM1 reveal that the highest sequence divergence between human, murine, canine and bovine orthologues is found in the β-strands comprising the bacteria-binding ...

Our previous in vitro data suggested that CEACAM1 is involved in angiogenesis. This is supported by a recent proteomic screen for cell membrane components expressed in newly formed tumor vessels and the fact that CEACAM1 expression is upregulated in synergy with other angiogenic factors in cardiac hypoxia (17, 19). To date, however, evidence for a causal implication of CEACAM1 in angiogenesis in vivo was lacking. In the present study, we report on 2 different genetic mouse models in which the angiogenic action of CEACAM1 has been investigated: in CEACAM1endo+ mice, the expression of CEACAM1-L was targeted to endothelia via the Tie2 promoter, and in Ceacam1-/- mice, the Ceacam1 gene was inactivated by targeted disruption (29). In addition, endothelial cells were transfected with cDNAs coding for WT CEACAM1-L and for CEACAM1-L mutants harboring amino acid substitutions in the cytoplasmic domain. In these experimental systems, we provide conclusive evidence that CEACAM1 is involved in angiogenesis ...

To assess the importance of the SLAM-MV interactions for virus spread and pathogenesis, we generated a wild-type IC-B MV selectively unable to recognize human SLAM (SLAM-blind). This virus differs from the fully virulent wild-type IC-B strain by a single arginine-to-alanine substitution at amino acid 533 of the attachment protein hemagglutinin and infects cells through SLAM about 40 times less efficiently than the isogenic wild-type strain. Ex vivo, this virus infects primary lymphocytes at low levels regardless of SLAM expression. When a group of ...

Although dexamethasone (DEX), a synthetic glucocorticoid receptor (GR) analog with profound effects on energy metabolism, immune system, and hypothalamic-pituitary-adrenal axis, is widely used therapeutically, its impact on the brain is poorly understood. The aim of the present study was to explore the effect of repeated low-dose DEX administration on the activity and expression of the ectonucleotidase enzymes which hydrolyze and therefore control extracellular ATP and adenosine concentrations in the synaptic cleft. Ectonucleotidases tested were ectonucleoside triphosphate diphosphohydrolase 1-3 (NTPDase1-3) and ecto-5-nucleotidase (eN), whereas the effects were evaluated in two brain areas that show different sensitivity to glucocorticoid action, hippocampus, and cerebral cortex. In the hippocampus, but not in cerebral cortex, modest level of neurodegenerative changes as well as increase in ATP, ADP, and AMP hydrolysis and upregulation of NTPDase1 and eN mRNA expression ensued under t...he ...

Epub Apr 01, 2011 ISSN 1414-431X. http://dx.doi.org/10.1590/S0100-879X2011007500044.. Gadolinium (Gd) blocks intra- and extracellular ATP hydrolysis. We determined whether Gd affects vascular reactivity to contractile responses to phenylephrine (PHE) by blocking aortic ectonucleoside triphosphate diphosphohydrolase (E-NTPDase). Wistar rats of both sexes (260-300 g, 23 females, 7 males) were used. Experiments were performed before and after incubation of aortic rings with 3 µM Gd. Concentration-response curves to PHE (0.1 nM to 0.1 mM) were obtained in the presence and absence of endothelium, after incubation with 100 µM L-NAME, 10 µM losartan, or 10 µM enalaprilat. Gd significantly increased the maximum response (control: 72.3 ± 3.5; Gd: 101.3 ± 6.4%) and sensitivity (control: 6.6 ± 0.1; Gd: 10.5 ± 2.8%) to PHE. To investigate the blockade of ...

The great majority of mammalian genes yield multiple transcripts arising from differential mRNA processing, but in very few instances have alternative forms been assigned distinct functional properties. We have cloned and characterized a new isoform of the accessory molecule CD6 that lacks the CD166 binding domain and is expressed in rat and human primary cells. The novel isoform, CD6Deltad3, results from exon 5 skipping and consequently lacks the third scavenger receptor cysteine-rich (SRCR) domain of CD6. Differential expression of the SRCR domain 3 resulted in a remarkable functional difference: whereas full-length CD6 targeted to the immunological synapse, CD6Deltad3 was unable to localize at the T cell:APC interface during Ag presentation. Analysis of expression of CD6 variants showed that, while being more frequent in coexpression with full-length CD6, the CD6Deltad3 isoform constituted the sole species in a small percentage of T cells. In the rat thymus, CD6Deltad3 is less represented in double

Background T-cell depletion therapy is associated with diminished interleukin (IL)-7/IL-15-dependent homeostatic proliferation resulting in incomplete T-cell repopulation. Furthermore, it is associated with impaired T-cell functions. We hypothesized that this is the result of impaired cytokine responsiveness of T cells, through affected signal transducer and activator of transcription (STAT)5 phosphorylation and upregulation of coinhibitory molecules. Materials and Methods Patients were treated with T cell-depleting rabbit antithymocyte globulin (rATG) (6 mg/kg, n = 17) or nondepleting, anti-CD25 antibody (basiliximab, 2 × 40 mg, n = 25) induction therapy, in combination with tacrolimus, mycophenolate mofetil, and steroids. Before and the first year after transplantation, IL-7 and IL-2 induced STAT5 phosphorylation, and the expression of the coinhibitory molecules programmed cell death protein 1 (PD-1), T cell immunoglobulin mucin-3 (TIM-3), lymphocyte activation gene-3 (LAG-3), cytotoxic ...

The T cell surface molecule CD28 can provide costimulatory signals that permit the full activation of T cells. Here we demonstrate that stimulation of CD28, either by B7, its natural ligand, or by the anti-CD28 monoclonal antibody 9.3, induces an association between CD28 and phosphatidylinositol 3-kinase (PI3-K) in Jurkat T cells, raising the possibility that an interaction with PI3-K contributes to CD28-mediated signaling. To examine the mechanism of the association, we synthesized tyrosine-phosphorylated oligopeptides corresponding to each of the four tyrosines in the CD28 cytoplasmic domain. When added to lysates of B7-stimulated Jurkat cells, the oligopeptide corresponding to Tyr 173 inhibits the coimmunoprecipitation of PI3-K with CD28; the other oligopeptides have no effect. Tyr 173 is contained within the sequence YMNM, a motif that is also found in the platelet-derived growth factor receptor and that, when phosphorylated, forms a high affinity binding site for the p85 subunit of PI3-K. ...

T-cell infiltration of solid tumors is associated with improved prognosis and favorable responses to immunotherapy. Mechanisms that enable tumor infiltration of CD8+ T cells have not been defined, nor have drugs that assist this process been discovered. Here we address these issues with a focus on VE-cadherin, a major endothelial cell-specific junctional protein that controls vascular integrity. A decrease in VE-cadherin expression is associated with tumor pathology. We developed an oligonucleotide-based inhibitor (CD5-2), which disrupted the interaction of VE-cadherin with its regulator miR-27a, resulting in increased VE-cadherin expression. Administration of CD5-2 in tumor-bearing mice enhanced expression of VE-cadherin in tumor endothelium, activating TIE-2 and tight junction pathways and normalizing vessel structure and function. CD5-2 administration also enhanced tumor-specific T-cell infiltration and spatially redistributed CD8+ T cells within the tumor parenchyma. Finally, CD5-2 treatment ...

The emergence of immune checkpoint inhibitors for solid tumor treatments represents a major oncological advance. Since the approval of ipilimumab, a cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) antibody, for the treatment of metastatic melanoma, many drugs, especially those targeting PD1/PD-L1, have demonstrated promising antitumor effects in many types of cancer. By reactivating the immune system (IS), these immunotherapies have led to the development of new toxicity profiles, also called immune-related adverse events (irAEs). IrAEs can involve many organ systems, and their management is radically different from that of cytotoxic drugs; irAEs require immunosuppressive treatments, such as corticoids or tumor necrosis factor alpha (TNFα) antibody. Additionally, the occurrence of irAEs has raised significant questions. Here, we summarize progress that has been made toward answering these questions, focusing on 1) the impact of immunotherapy dose on irAE occurrence, 2) the correlation ...

We could not confirm the inhibitory effect of Th3 cells on immune responses at inflammatory sites, as TGF-β1 mRNA expression did not correlate with the frequency of sensitization or dose in this antigen induced inflammation model. CD4+CD25+T cells. express cytotoxic T-lymphocyte antigen 4 (CTLA-4) with membrane-associated TGF-β on the cell surface, which suppresses multiplication of positive effector T cells by direct cytoadherence [33, 34]. Foxp3, a master regulatory gene is constitutively expressed in CD4+CD25+T cells [35], and both Tr1 and Th3 cells see more are negative for Foxp3 [36, 37]. It was assumed that intrapulmonary Foxp3 mRNA expression is not increased as drastically in comparison with IL-10, as frequent and large quantity sensitization with M. pneumoniae antigens induced CD4+CD25+T cell translocation from thymus to the. lung. Additionally, we performed an in vitro analysis aimed to evaluate the specificity of immuno-inducibility and Th17-differentiation enhancability of M. ...

T cells (thymus cells) and B cells (bone cells) are the main cells of the adaptive immune response. They tackle infections, and they cause the immune system to remember the event. The function of T cells and B cells is to recognize foreign antigens. Antigens are surface molecules on a cell. Once they have identified an invader, the cells respond to remove pathogens or pathogen-infected cells. B cells respond to pathogens by producing large numbers of antibodies which then destroy foreign objects like bacteria and viruses. Some T cells, called T helper cells, produce cytokines that direct the immune response. Cytokines signal to other immune cells that there is a foreign antigen present. Other T cells, called cytotoxic T cells, produce toxic granules which cause the death of infected cells. Once they are made active, B cells and T cells produce memory cells. Throughout the lifetime of an animal, these cells will remember each specific pathogen encountered, and are able to make a strong ...

One reason for the poor immunogenicity of many tumors may be that they cannot provide signals for CD28-mediated costimulation necessary to fully activate T cells. It has recently become apparent that CTLA-4, a second counterreceptor for the B7 family of costimulatory molecules, is a negative regulator of T cell activation. Here, in vivo administration of antibodies to CTLA-4 resulted in the rejection of tumors, including preestablished tumors. Furthermore, this rejection resulted in immunity to a secondary exposure to tumor cells. These results suggest that blockade of the inhibitory effects of CTLA-4 can allow for, and potentiate, effective immune responses against tumor cells.. ...
