7532543
|
Culture of CD34+ HPC with granulocyte-macrophage-colony-stimulating factor and tumor necrosis factor alpha yielded a heterogeneous cell population containing cells with typical dendritic morphology.
|
6 |
7532543
|
Phenotypic studies demonstrated a loss of the CD34 molecule over 1 week and an increase in cells expressing surface markers associated with dendritic cells, CD1a, CD80 (B7/BB1), CD4, CD14, HLA-DR, and CD64 (Fc gamma RI).

|
The synergistic anti-tumor effects associated with combined application of B7.1- and IL-12-transfected tumors were partially negated by systemic administration of the CD28-B7.1/B7.2 antagonist CTLA4-Ig or by inoculation with neutralizing antibodies directed against murine interferon-gamma or tumor necrosis factor-alpha, two cytokines elicited in response to IL-12 stimulation.

|
LC were CD1a+2 DR+2, CD23+, CD36+, CD80-, CD86-, and CD25-, while DC were CD1a+/- DR+3, CD23-, CD36-, CD80+, CD86+2, and CD25+, CD40 and CD32 were moderately expressed and nearly unchanged on maturation, in contrast to monocyte-derived DC.

They neo-expressed CD1a, CD1b, CD1c, CD80, and CD5; they massively up-regulated CD40 (109-fold) and HLA-DQ and DP (125- and 87-fold); and significantly (>5-fold) up-regulated HLA-DR, CD4, CD11b, CD11c, CD43, CD45, CD45R0, CD54, CD58, and CD59.
|
16 |
8892615
|
CD14, CD15s, CD64, and CDw65 molecules were down-regulated to background levels, and no major changes were observed for HLA class I, CD11a, CD32, CD33, CD48, CD50, CD86, CDw92, CD93, or CD97.

|
The second, costimulatory signal can be provided by cell surface molecules on APCs such as B7-1 (CD80) and B7-2 (CD86), which interact with their counter-receptors on T cells.
|
22 |
9144470
|
Our approach is based on a chimeric fusion protein that consists of the extracellular domain of human B7-2 fused to a single-chain Ab domain (scFv) specific for the ErbB2 protein, a type I growth factor receptor overexpressed in a high percentage of human adenocarcinomas.
|
23 |
9144470
|
This B7-2(225)-scFv(FRP5) molecule expressed in the yeast Pichia pastoris and purified from culture supernatants is functionally active and binds to B7 counter-receptors and to ErbB2.
|
24 |
9144470
|
B7-2(225)-scFv(FRP5) localizes specifically to the surface of ErbB2-expressing target cells, thereby providing a costimulatory signal that results in enhanced proliferation of syngeneic T cells.

While of the 9 lines tested 4 (INT.Ov1, 2, 5 and 6) expressed the folate receptor (FR-alpha) and 6 (INT.Ov1, 2, 5, 6, 7 and 9) expressed the epidermal growth factor receptor (EGFR); MAGE-1 and p185HER-2/neu were only found in 2 lines (INT.Ov1 and 2) and GAGE-1 expression in 1 line (INT.Ov2).
|
36 |
9334822
|
The identification of class I MHC ligands and T-cell epitopes within protein antigens was achieved by applying several theoretical methods including: 1) similarity or homology searches to MHCPEP; 2) BIMAS and 3) artificial neural network-based predictions of proteins MAGE, GAGE, EGFR, p185HER-2/neu and FR-alpha expressed in INT.Ov lines.

Because these mice retained their ability to up-regulate the CTLA4 receptor (a negative regulator of T cell activation), we examined CTLA4's role in the response of wild-type BALB/c mice to NAV.
|
41 |
9510170
|
Intact anti-CTLA4 mAb but not Fab fragments suppressed the primary humoral response to pCIA/beta gal without affecting recall responses, indicating CTLA4 activation inhibited Ab production but not T cell priming.
|
42 |

Immunoliposomes containing monoclonal antibodies (MAbs) to the costimulatory molecules CD28 and CTLA4 and their counterreceptors B7-1 (CD80) and B7-2 (CD86) were evaluated for the ability to increase the immune response to recombinant envelope protein rgp120 of the MN strain of human immunodeficiency virus type 1 (HIV-1) during vaccination.
|
65 |
9546800
|
The DTH response was not accompanied by increased production of interferon gamma (IFN-gamma) or interleukin 4 (IL-4), implying that the primary cellular interaction was between the immunoliposomes and cells of the reticuloendothelial system and not helper T (Th) cells.

|
DC progenitors from peripheral blood mononuclear cells (PBMC) were enriched by adherence to plastic, and the adherent cells were then cultured in serum-free XVIVO-15 medium (SFM) for 7 days with added granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4).
|
68 |
9616162
|
Moreover, 14-day cultured DC generated in the presence of TNFalpha (when added at day 7) demonstrated marked enhancement in their capacity to stimulate a primary allogeneic mixed leukocyte reaction (8-fold increase in stimulation index [SI]) as well as to present soluble tetanus toxoid and candida albicans (10- to 100-fold increases in SI) to purified CD4+ T cells.
|
69 |
9616162

Enhancement of antitumor immunity by expression of CD70 (CD27 ligand) or CD154 (CD40 ligand) costimulatory molecules in tumor cells.
|
71 |
9622100
|
CD70 (CD27 ligand (CD27L)), CD153 (CD30L), and CD154 (CD40L) are members of the tumor necrosis factor family of costimulatory molecules and expressed on the surface of T cells that are important for both T- and B-cell help.
|
72 |
9622100
|
We examined the capacity for expression of these tumor necrosis factor family members on tumor cells to induce an antitumor response either in the presence or absence of interleukin 12.
|
73 |
9622100
|
Retroviral vectors were constructed that expressed high levels of membrane bound CD70, CD153, or CD154 following infection and selection of the murine tumor lines MCA 207 or TS/A.
|
74 |
9622100
|
When tested for tumor establishment, the expression of either CD70 or CD154 was able to slow tumor growth.
|
75 |
9622100
|
Similarly, CD70 or CD154 were able to induce antitumor immunity at a higher frequency when tested in vaccination and therapy models.
|
76 |
9622100
|
CD70 was able to induce antitumor immunity at a level similar to CD80 when tested either in the presence or absence of interleukin 12.

|
Moreover, coexpression of CD70 and CD80 was able to synergize the induction of a higher frequency of antitumor immunity in a vaccination model.
|
78 |
9622100
|
Taken together, our results suggest that CD154 and in particular CD70 are able to contribute to the induction of the immune response to tumor in murine models and thus may be of use for human clinical trials.

Gene transfer of costimulatory molecules into a human colorectal cancer cell line: requirement of CD54, CD80 and class II MHC expression for enhanced immunogenicity.
|
91 |
9640250
|
Using transfected variants of the human colorectal cancer cell line SW480 we tested various costimulatory molecules (CD80, CD86, CD54) and a class II major histocompatibility complex (MHC) allele (HLA-DR3) alone or in combination on their ability to support primary T-lymphocyte activation in vitro.
|
92 |
9640250
|
Expression of CD80 or CD86 similarly as the combination of both was not sufficient to induce proliferation of human allogeneic T cells.
|
93 |
9640250

Expression of CD54 together with CD80 strongly augmented the costimulatory function of CD80, as observed in the presence of a CD3 monoclonal antibody (mAb), but did not lead directly to a T-cell response against modified tumour cells.
|
94 |

|
Importantly, SW480 cells coexpressing CD54, CD80 and the HLA-DR3 allele effectively promoted T-lymphocyte proliferation.
|
95 |
9640250
|
Moreover, the use of such CD54+/CD80+/HLA-DR3+ SW480 variants for repetitive stimulations resulted in the generation of T-cell lines predominantly composed of CD8+ T cells exhibiting class I MHC restricted cytolytic activity towards untransfected SW480 tumour cells.

Gene transfer of costimulatory molecules into a human colorectal cancer cell line: requirement of CD54, CD80 and class II MHC expression for enhanced immunogenicity.
|
121 |
9640250
|
Using transfected variants of the human colorectal cancer cell line SW480 we tested various costimulatory molecules (CD80, CD86, CD54) and a class II major histocompatibility complex (MHC) allele (HLA-DR3) alone or in combination on their ability to support primary T-lymphocyte activation in vitro.
|
122 |

|
Expression of CD80 or CD86 similarly as the combination of both was not sufficient to induce proliferation of human allogeneic T cells.
|
123 |
9640250
|
Expression of CD54 together with CD80 strongly augmented the costimulatory function of CD80, as observed in the presence of a CD3 monoclonal antibody (mAb), but did not lead directly to a T-cell response against modified tumour cells.
|
124 |
9640250
|
Importantly, SW480 cells coexpressing CD54, CD80 and the HLA-DR3 allele effectively promoted T-lymphocyte proliferation.

After separation, the negative fraction of mobilized PBMCs from normal donors and cancer patients contained undetectable levels of CD34+ HSCs by flow cytometry.
|
139 |
9829733
|
This fraction of cells was then subjected to plastic adherence, and the adherent cells were cultured for 7 days in GM-CSF (100 ng/ml) and interleukin 4 (50 ng/ml) followed by an additional 7 days in GM-CSF, interleukin 4, and tumor necrosis factor alpha (10 ng/ml) to generate DCs.
|
140 |
9829733
|
Harvested DCs represented yields of 4.1+/-1.4 and 5.8+/-5.4% of the initial cells plated from the CD34+ cell-depleted mobilized PBMCs of normal donors and cancer patients, respectively, and displayed a high level expression of CD80, CD86, HLA-DR, and CD11c but not CD14.
|
141 |
9829733

We compared the efficacy of BM185 cell vaccine expressing CD80 alone or in combination with IL-2 or GM-CSF.
|
236 |
10498243

Mice injected with viable BM185 leukemia cells modified to express CD80 and GM-CSF (BM185/CD80+GM-CSF) showed the highest leukemia rejection rates.
|
237 |
10498243
|
Cell vaccines consisting of irradiated BM185/CD80+GM-CSF cells administered subcutaneously stimulated a potent cytotoxic T lymphocyte (CTL) response against parental BM185.
|
238 |
10498243
|
Administration of the BM185/CD80+GM-CSF cell vaccine before intravenous challenge with parental cells caused strong inhibition of leukemia development.

Rapid induction of CD40 on a subset of granulocyte colony-stimulating factor-mobilized CD34(+) blood cells identifies myeloid committed progenitors and permits selection of nonimmunogenic CD40(-) progenitor cells.
|
270 |
10498601
|
CD40 antigen is a costimulatory molecule highly expressed on dendritic cells (DC) and activated B cells, which induces T-cell proliferation through the binding with CD40L receptor.
|
271 |
10498601
|
CD40, CD80, and CD86 antigens were constitutively expressed on 3.2% +/- 4.5%, 0%, and 1.8% +/- 1.2% CD34(+) blood cells, respectively.
|
272 |
10498601
|
However, after 24 hours in liquid culture with medium alone, or with tumor-necrosis-factor-alpha (TNF-alpha), or with allogeneic mononuclear cells 10.8% +/- 3.8%, 75.3% +/- 15.0% and 53. 7% +/- 17.0% CD34(+) blood cells, respectively, became CD40(+).
|
273 |
10498601
|
After incubation for 24 hours with TNF-alpha CD34(+)CD40(+) blood cells expressed only myeloid markers and contained less than 5% CD86(+) and CD80(+) cells.
|
274 |
10498601
|
Also, a 24-hour priming with TNF-alpha or ligation of CD40 significantly increased the CD34(+) blood cells alloantigen presenting function.
|
275 |
10498601
|
Finally, purified CD34(+)CD40(+) blood cells stimulated an alloreactive T-cell response in MLC, were enriched in granulocytic, monocytic, and dendritic precursors, and generated high numbers of DC in 11-14 d liquid cultures with GM-CSF, SCF, TNF-alpha and FLT-3L.
|
276 |
10498601
|
In conclusion, a short incubation with TNF-alpha allows the selection of CD40(+) blood progenitors, which may be a useful source of DC precursors for antitumor vaccine studies, and also a CD34(+)CD40(-) blood cell fraction that could be exploited in innovative strategies of allogeneic transplantation across HLA barriers.

Previously, we demonstrated that a novel low-molecular-weight synthetic immune response modifier, R-848, induces IL-12 and IFN-alpha secretion from monocytes and macrophages.
|
286 |
10555997
|
Characteristic of dendritic cell maturation, R-848 treatment induces cell surface expression of CD83 and increases cell surface expression of CD80, CD86, CD40, and HLA-DR.
|
287 |
10555997
|
Additionally, R-848 induces cytokine (IL-6, IL-12, TNF-alpha, IFN-alpha) and chemokine (IL-8, MIP-1alpha, MCP-1) secretion from dendritic cells.
|
288 |
10559341
|
We now show that infection by rAd enhances the immunostimulatory capacity of immature human monocyte-derived DC through the upregulation of the costimulatory molecules CD80, CD86, and CD40 and the major histocompatibility complex class I and II molecules.
|
289 |
10559341
|
Although rAd infection fails to induce the secretion of interleukin-12 (IL-12) and only marginally induces the expression of the DC maturation marker CD83, it acts in synergy with CD40 triggering in rendering DC fully mature. rAd-infected DC triggered through CD40 produce more IL-12 and are more efficient in eliciting T-helper type 1 responses than DC activated by CD40 triggering only. rAd lacking one or more of the early regions, E1, E2A, E3, and E4, which play an important role in virus-host cell interactions are equally capable of DC activation.

After a 6-h incubation, phenotypic analysis of control-, imiquimod-, or R-848-treated LC indicated that such antigen-presenting cells were in an "intermediate" state of maturation (CD1a(+), HLA-DR, DP, DQ(bright+), CD40(low+), CD86(high+), and CD80(low+)).
|
291 |
10607486
|
RNase protection assays demonstrated that either imiquimod or R-848 treatments increased steady-state transcripts encoding for IL-12 p40, IL-1beta, TNF-alpha, and IL-1 receptor antagonist by LC.

Vaccination with mouse mammary adenocarcinoma cells coexpressing B7-1 (CD80) and B7-2 (CD86) discloses the dominant effect of B7-1 in the induction of antitumor immunity.
|
293 |
10623812
|
Nonreplicating TS/A mammary adenocarcinoma cells expressing B7-2 (CD86) (TS/A-2) are more immunogenic than those expressing B7-1 (CD80) (TS/A-1), indicating that B7-1 and B7-2 display nonredundant costimulatory effects in inducing antitumor responses.
|
294 |
10623812
|
The expression of B7-1 also modifies quantitatively the balance of endogenous IFN-gamma and IL-4 induced in vivo by TS/A-2 vaccines.
|
295 |
10623812
|
In fact, we find that vaccination with TS/A-2/1 cells results in the production of more IFN-gamma and less IL-4 than TS/A-2 vaccines, a pattern comparable to that induced by TS/A-1 cells.

|
These admixed cells were rejected by 14 of 15 (MC38) or seven of 15 mice (MCA205), whereas, a mixture of IFN-alpha and Neo cells or CD80 and Neo cells led to tumors associated with progressive growth.

It is well known that tumor cells that express B7 molecules can elicit antitumor immunity, but little is known regarding which B7 molecule, B7-1 (CD80) or B7-2 (CD86), can do so more efficiently.
|
343 |
10678367
|
In vivo depletion of lymphocyte subsets demonstrated that both CD4+ and CD8+ T cells were indispensable for B7-1- or B7-2-dependent antitumor immunity, whereas natural killer cells were not.

The generation of DC from blood monocytes in response to GM-CSF and IL-4 treatment was similar in cells from young and old persons.
|
345 |
10689136
|
The DC population thus obtained had a typical dendritic morphology and expressed DC surface markers, such as HLA class II, CD1a, CD11c, CD54, CD80 and CD86, but not CD14 for a period of up to three weeks in culture.
|
346 |

Irradiation of genetically modified plasmacytoma vaccines results in upregulation of CD80 molecule expression, IL-2 production and higher therapeutic efficacy of the vaccines.
|
349 |
10730877
|
In this communication, we have demonstrated that irradiation of murine IL-2-producing plasmacytoma vaccines resulted in upregulation of CD80 molecule expression and IL-2 production.
|
350 |
10730877
|
The upregulation of the CD80 membrane molecule expression in X63-m-IL-2 cells was higher after irradiation with 150 Gy than after irradiation with 50 Gy.
|
351 |
10730877
|
The results indicate that upregulation of the CD80 molecule expression and enhanced IL-2 production in irradiated X63-m-IL-2 cells was responsible for the higher therapeutic effectiveness of the irradiated plasmacytoma vaccine.

|
In this communication, we have demonstrated that irradiation of murine IL-2-producing plasmacytoma vaccines resulted in upregulation of CD80 molecule expression and IL-2 production.
|
354 |
10730877
|
The upregulation of the CD80 membrane molecule expression in X63-m-IL-2 cells was higher after irradiation with 150 Gy than after irradiation with 50 Gy.
|
355 |
10730877
|
The results indicate that upregulation of the CD80 molecule expression and enhanced IL-2 production in irradiated X63-m-IL-2 cells was responsible for the higher therapeutic effectiveness of the irradiated plasmacytoma vaccine.

Immunotherapy with vaccines combining MHC class II/CD80+ tumor cells with interleukin-12 reduces established metastatic disease and stimulates immune effectors and monokine induced by interferon gamma.
|
365 |
10782864
|
Two such mouse models are used in this report to demonstrate the therapeutic efficacy and to probe the mechanisms of a novel combination immunotherapy consisting of the cytokine interleukin-12 (IL-12) combined with a previously described vaccine based on MHC class II, CD80-expressing cells.
|
366 |
10782864
|
C57BL/6 mice with 7-day established intravenous B16 melF10 lung metastases show a similar response following immunotherapy with IL-12 plus a vaccine based on B16 MHC class II, CD80-expressing cells.
|
367 |
10782864
|
In both systems the combination therapy of cells plus IL-12 is more effective than IL-12 or the cellular vaccine alone, although, in the 4T1 system, optimal activity does not require MHC class II and CD80 expression in the vaccine cells.
|
368 |
10782864
|
The cell-based vaccines were originally designed to activate tumor-specific CD4+ T lymphocytes specifically and thereby provide helper activity to tumor-cytotoxic CD8+ T cells, and IL-12 was added to the therapy to facilitate T helper type 1 lymphocyte (Th1) differentiation.
|
369 |
10782864
|
In vivo depletion experiments for CD4+ and CD8+ T cells and natural killer (NK) cells and tumor challenge experiments in beige/nude/XID immunodeficient mice demonstrate that the therapeutic effect is not exclusively dependent on a single cell population, suggesting that T and NK cells are acting together to optimize the response.
|
370 |
10782864
|
IL-12 may also be enhancing the immunotherapy via induction of the chemokine Mig (monokine induced by interferon gamma), because reverse PCR experiments demonstrate that Mig is present in the lungs of mice receiving therapy and is most likely synthesized by the tumor cells.

The expression of major histocompatibility complex class II, CD80, CD86 and CD11c by BMDC after phagocytosing rBCG or inert beads, was inhibited when the BMDC were pretreated with IL-10.

Here, we test in this postsurgical model, a novel cell-based vaccine, combining MHC class II, CD80(B7.1), and SEB superantigen.
|
394 |

|
These therapeutic effects are particularly noteworthy because: (a) the postoperative model demonstrates that early metastases responsible for morbidity are established by 2 weeks after tumor inoculation with 7 x 10(3) parental 4T1 cells into the mammary gland; (b) the immunotherapy is started 4 weeks after tumor inoculation when the mice contain extensive, pre-established, disseminated metastases; and (c) CD4+ and CD8+ T cells are required for the effect.

For example, coadministration of costimulatory molecules (CD80 and CD86), proinflammatory cytokines (interleukin-1alpha [IL-1alpha], tumor necrosis factor-alpha [TNF-alpha, and TNF-beta), Th1 cytokines (interleukin-2 [IL-2], IL-12, IL-15, and IL-18), Th2 cytokines (IL-4, IL-5, and IL-10), and granulocytes-macrophage colony-stimulating factor (GM-CSF) with DNA vaccine constructs leads to modulation of the magnitude and direction (humoral or cellular) of the immune responses.
|
396 |
10841077
|
To further engineer the immune response in vivo, we compared the induction and regulation of immune responses from the codelivery of chemokine (IL-8, interferon-gamma-inducible protein-10 [gammaIP-10], macrophage inhibitory protein-1alpha [MIP-1alpha], and RANTES) genes with codelivery of cytokine genes.
|
397 |
10841077
|
We observed that coimmunization with IL-8, gammaIP-10, and MIP-1alpha genes increased the antibody response.
|
398 |
10841077
|
We also found that coinjection with IL-8, gammaIP-10, and RANTES resulted in a dramatic enhancement of T helper (Th) proliferation response.
|
399 |
10841077
|
This enhancement of CTL responses observed from the coinjection with RANTES was CD8+ T cell dependent.
|

|
Thus, LPS-matured dendritic cells (DC1) promote a Th1 response (increased generation of IFN-gamma and reduced production of IL-4) by Ag-stimulated CD4+ T cells from the DO.11.10 transgenic mouse expressing a TCR specific for an OVA peptide (OVA323-339).
|
401 |
10843701
|
In contrast, a phosphorylcholine-containing glycoprotein, ES-62, secreted by the filarial nematode, Acanthocheilonema viteae, which generates a Th2 Ab response in vivo, is found to induce the maturation of dendritic cells (DC2) with the capacity to induce Th2 responses (increased IL-4 and decreased IFN-gamma).
|
402 |
10843701
|
In addition, we show that the switch to either Th1 or Th2 responses is not effected by differential regulation through CD80 or CD86 and that a Th2 response is achieved in the presence of IL-12.

A strong delayed-type hypersensitivity (DTH) reaction was induced in mice co-injected via the intradermal (i.d.) route with a eukaryotic expression plasmid encoding the CD80 molecule (pCD80) and a plasmid encoding the glycoprotein D of the HSV-2 (pgD).
|
404 |
10886404
|
Furthermore, when spleen cells from these mice were cultured in the presence of inactivated HSV, a significant increase in the expression of interleukin-2 receptor (IL-2R) was observed in the CD4 subset compared with mice immunized only with pgD.
|
405 |
10886404
|
Analysis of cytokine synthesis at the single-cell level indicated that CD80 genes induce a significant increase in the number of interferon-gamma (IFN-gamma)-, IL-2- and IL-4-secreting cells in the spleen.
|
406 |
10886404
|
When a plasmid carrying the CD86 gene (pCD86) was co-injected via the i.m. route with the pgD plasmid, a small decrease in the number of IFN-gamma-secreting cells was observed.
|
407 |
10886404

Cells displayed a characteristic iDC phenotype (CD1a(+), CD14(-), CD80(+), CD86(+), HLA DR(+), CD83(-)), and had potent allogeneic and antigen dependent autologous T cell-stimulatory capacity.
|
420 |
10915850
|
Moreover, iDC could be further differentiated into mature DC by CD40 ligation as assessed by CD83 expression and the upregulation of HLA-DR and costimulatory molecules.

Influenza vaccine stimulated significantly lower production of interferon-gamma (IFN-gamma) compared with live and heat inactivated viruses, whereas both vaccine and heat-inactivated influenza induced lower levels of IFN-alpha compared with live virus.
|
431 |
11053627
|
A significant increase in monocyte expression of CD80, CD86, CD40, and human leukocyte antigen-DR (HLA-DR) was also induced by live influenza virus.
|
432 |
11053627
|
Our results suggest that immunization with live influenza vaccines might induce immune responses that would not be induced by conventional inactivated vaccines, including CTL generation, antiviral IFN-gamma and IFN-alpha cytokine production, and increased antigen presentation and costimulatory capacity on antigen presenting cells (APC).

11228537
|
FACS analysis of parental B78 melanoma cells and its B78/TNF genetically modified variant showed that a proportion of cells of both cell lines expressed 87-1 (CD80) costimulatory molecule and that the expression of this molecule was increased during incubation with IFN-gamma.
|
541 |
11228537
|
Moreover, IFN-gamma markedly augmented expression of major histocompatibility class (MHC) class I and II molecules on B78/TNF cells that were primarily MHC class I and II negative with no substantial effect on MHC-negative parental B78 melanoma.
|
542 |
11228537
|
IFN-gamma also synergized in cytostatic/cytotoxic effects with TNF-alpha against B78 melanoma in vitro.
|
543 |
11228537
|
The results suggest that, when used therapeutically, IL-12 and a vaccine containing TNF-alpha gene-transduced tumor cells may reciprocally augment their overall antitumor effectiveness by facilitating development of systemic antitumor immunity and by stimulating local effector mechanisms of the tumor destruction.

11591784
|
A carcinoembryonic Ag (CEA)-based DNA vaccine encoding both CEA and CD40 ligand trimer achieved effective tumor-protective immunity against murine colon carcinoma in CEA-transgenic mice by activating both naive T cells and dendritic cells.
|
583 |
11591784
|
Peripheral T cell tolerance to CEA was broken in a prophylactic model by this novel, dual-function DNA vaccine, whose efficacy was further enhanced by boosts with a recombinant Ab-IL-2 fusion protein (huKS1/4-IL-2).
|
584 |
11591784
|
Second, specific activation of dendritic cells was indicated by their marked up-regulation in expression of costimulatory molecules B7.1 (CD80), B7.2 (CD86), and ICAM-1.
|
585 |
11591784
|
Third, a decisive increase over control values was observed in both MHC class I Ag-restricted cytotoxicity of CTLs from successfully vaccinated mice and secretion of proinflammatory cytokines IFN-gamma and IL-12.
|
586 |
11591784
|
Fourth, activation of CTLs was augmented, as indicated by up-regulation of activity markers LFA-1, CD25, CD28, and CD69.
|
587 |
11591784
|
Taken together, these results suggest that a dual-function DNA vaccine encoding CEA and CD40 ligand trimer combined with tumor-targeted IL-2 may be a promising strategy for the rational development of DNA-based cancer vaccines for future clinical applications.

We have analysed the functional capability of DC generated in vitro from blood CD14(+) cells of chronic lymphocytic leukaemia (CLL) patients and healthy donors by culturing for 10 d with granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin 4 (IL-4) and tumour necrosis factor-alpha (TNF-alpha).
|
593 |

Expression of single-chain HLA was complemented step-by-step with costimulatory molecules, including CD54 and CD80, by co-infection with the relevant viruses.
|
628 |
11754359
|
We found that the HLA+peptide complex alone displayed on the surface of insect cells was sufficient to elicit IFN-gamma secretion from these freshly isolated CD8(+) T cells in ELISpot assays.
|
629 |
11754359
|
The amount of IFN-gamma produced by the individual reactive T cells was evaluated as spot size, and was also influenced by the costimulatory molecules: CD54 increased also the response magnitude of cultured CTL lines, while CD80 enhanced cytokine release from freshly isolated CD8(+) T cells.

634 |
11759072
|
Multiple subcutaneous administrations of tumor lysate-pulsed dendritic cells (TP-DCs) resulted in an approximately eightfold hypertrophy of the vaccine draining nodes, with an increased influx of dendritic (CD11c+/CD80+) cells and B (B220+) cells.
|
635 |
11759072

11777991
|
Maturation parameters such as production of IL-12 and increases in cell surface expression of HLA-DR, CD80, CD86, CD40, and CD83 were observed following DC treatment with MPL.
|
637 |
11777991
|
This is likely to be related to differences in the kinetics of extracellular signal-related kinase 1/2 and p-38 phosphorylation induced by both molecules.
|
638 |
11777991
|
The observed effect was related to the fact that MPL also acts directly on T cells, likely through their Toll-like receptors, by increasing their intracellular calcium and up-regulating their CD40 ligand expression.
|
639 |
11781244
|
Infection induced DC morphology and altered the expression of surface markers, including loss of CD14, de novo induction of CD83 and CD25, and strongly augmented expression of CD86, CD80, CD40, and HLA-DR and HLA class I molecules.

640 |
11792391
|
Characteristic immunophenotypic and functional DC maturation induced by standard monocyte conditioned medium (MCM) was compared to the activation induced by a panel of stimuli including soluble CD40L, LPS, Poly I:C, PGE(2)/TNFalpha, and a cocktail mixture of PGE(2)/TNFalpha/IL-1beta/IL-6.
|
641 |
11792391
|
Immunophenotypic analysis confirmed that all stimuli induced stable up-regulation of CD25, CD40, CD80, CD83, CD86, HLA-DR, DC-LAMP (CD208), and DEC-205 (CD205).

Adenovirus-mediated CD40 ligand gene-engineered dendritic cells elicit enhanced CD8(+) cytotoxic T-cell activation and antitumor immunity.
|
649 |
11857039
|
CD40L, the ligand for CD40 on dendritic cells (DCs), plays an important role in their activation and is essential for induction of antigen-specific T-cell responses.
|
650 |
11857039
|
Our data show that transfection of DCs with recombinant adenovirus AdV-CD40L resulted in activation of DCs with up-regulated expression of proinflammatory cytokines (IL-1beta and IL-12), chemokines (RANTES, IP-10, and MIP-1alpha), and immunologically important cell surface molecules (CD54, CD80, and CD86).
|
651 |
11857039
|
Our data also demonstrate that DCs transfected with AdV-CD40L (DC(CD40L)) are able to stimulate enhanced allogeneic T-cell proliferation and Mut1-specific CD8(+) cytotoxic T-cell responses in vitro.
|
652 |
11857039
|
Thus, DCs engineered to express CD40L by adenovirus-mediated CD40 ligand gene transfer may offer a new strategy in production of DC cancer vaccines.

We distinguished a population of dendrite-like cells among the cells derived from the silica-treated peritoneal cavity both by their phenotype (MHC II(+)/CD80(+)/CD86(+)) and by their ability to induce the proliferation of allogeneic T cells in a mixed leukocyte reaction.
|
655 |
11902830
|
Mature DCs expressed significantly heightened levels of their antigen-presenting machinery (e.g., CD54, CD80, CD86) and numerous cytokines and chemokines/chemokine receptors (i.e., Flt-3L, G-CSF, IL-1alpha and -1beta, IL-6, IL-12, CCL-2, -3, -4, -5, -17, and -22, MIP-2, and CCR7) and were significantly better at inducing effector T cell responses in vitro.
|
656 |
11902830
|
Nevertheless, intermediate-maturity DCs expressed substantial levels of Flt-3L, IGF-1, IL-1alpha and -1beta, IL-6, CCL-2, -3, -4, -9/10, -17, and -22, MIP-2, osteopontin, CCR-1, -2, -5, and -7, and CXCR-4.

We have used a murine B-cell lymphoma model (A20) to study the in vivo antitumor effect of the administration of tumor cells transduced with a recombinant adenovirus encoding CD40L (AdvCD40L).
|
660 |
12036933
|
After infection with AdvCD40L, A20 tumor cells up-regulate several T-cell costimulatory molecules (CD80, CD86, ICAM-1, and LFA-3) and Fas expression.
|
661 |
12036933

In vivo depletion studies demonstrate that both CD4(+) and CD8(+) T cells mediate the antitumor immunity provided by AdvCD40L-transduced tumor cells.

663 |
12111122
|
We showed that bone marrow-derived DC pulsed with Id-CD40L upregulated the expression of CD40, CD80, CD86, and major histocompatibility complex (MHC) class II molecules with the increased production of interleukin-12 (IL-12).
|
664 |
12134231
|
Both native PT (nPT) and genetically detoxified PT (dPT) efficiently promoted expression on DCs of CD80, CD86, human leukocyte antigen-DR, and CD83 markers, alloreactive antigen presentation, and cytokine production, primarily interferon (IFN)-gamma.
|
665 |
12134231
|
Although they did not affect interleukin (IL)-10 production by lipopolysaccharide (LPS)-stimulated DCs, both nPT and dPT strongly synergized with LPS for IL-12 production.
|
666 |
12134231
|
PTs plus LPS-stimulated DCs secreted soluble factors fostering IFN-gamma but not IL-4 and IL-5 production by naive T cells.
|
667 |
12149420
|
Although BRSV did not appear to replicate in MoDC or to affect expression of major histocompatibility complex (MHC) class I, MHC class II, or CD80/86, a higher percentage of cells exposed to live virus appeared to undergo apoptosis/necrosis.
|
668 |
12149420
|
Exposure of MoDC to live BRSV induced more interleukin (IL)-10 mRNA and markedly less IL-12p40 and IL-15 mRNA than did heat-inactivated virus.
|
669 |
12149420
|
Stimulation of CD4(+) T cells induced similar levels of IL-2-and IL-4-like activity and interferon-gamma.
|
670 |
12149420
|
These observations suggest that while IL-10, produced by MoDC as a result of exposure to live BRSV, may affect IL-12 and IL-15 synthesis by MoDC, it does not appear to affect the cytokine response of BRSV-specific memory CD4(+) T cells.

|
673 |
12167647
|
Upon ligation by CD80 (B7-1) or CD86 (B7-2), CD28 induces T cell proliferation, cytokine production, and effector functions, whereas CTLA-4 signaling inhibits expansion of activated T cells and induces tolerance.

Cells obtained from 24 patients with B-CLL were infected with AAV/EGFP or AAV/CD40L at a multiplicity of infection (MOI) of 100 resulting in transgene expression in up to 97% of cells as detected by flow cytometry 48 hours after infection.
|
698 |
12176885
|
Transduction with AAV/CD40L resulted in up-regulation of the costimulatory molecule CD80 not only on infected CLL cells but also on noninfected bystander leukemia B cells, whereas this effect induced specific proliferation of HLA-matched allogeneic T cells.

DC(RMAT) displayed an up-regulated expression of immune molecules (Ia(d), CD40, CD54, CD80 and CD86) and certain cytokines/chemokines, and enhanced ability of allogeneic T cell stimulation when compared to DC(IMAT).

We propose to develop cell vaccines by genetic modification of AML cells with CD80, an essential T cell costimulator that is lacking in the majority of AML cases, and GM-CSF, to induce proliferation and activation of professional antigen-presenting cells.
|
702 |
12200676

CD80 and GM-CSF expression by these vectors was higher than that reported with second generation vectors (Stripecke et al, Blood 2000; 96: 1317-1326).
|
703 |
12200676

The transition from monocyte to DC is characterized by the up-regulation of CD83, CD86, CD80, CD40 and the down-regulation of CD14.
|
717 |
12218781
|
Mature DC expressed significant amounts of mature DC markers (CD83) and the costimulatory molecules CD80 and CD86.
|
718 |
12218781
|
These clinical grade DC secreted high levels of the chemokines dendritic cell chemokine 1 (DC-CK1), interleukin-8 (IL-8), macrophage-derived chemokine (MDC), and thymus and activation-regulated chemokine (TARC).

|
A recruitment of B220(+) and MAC-1(+) cells with an up-regulated expression of MHC class I, CD80 (B7.1) and CD54 (ICAM-1) was observed in nasal associated lymphoid tissues from MALP-2 treated mice.

In particular, ex vivo culture of ALL cells with CD40 ligand, incubation of AML cells with granulocyte-macrophage colony-stimulating factor and interleukin-4 (GM-CSF/IL-4) and lentiviral transduction of ALL and AML cells for expression of immunomodulators (CD80 and GM-CSF) are current approaches under investigation for the development of autologous acute leukemia cell vaccines.

CD28, TNF receptor, and IL-12 are critical for CD4-independent cross-priming of therapeutic antitumor CD8+ T cells.
|
722 |
12391201
|
Previously, we have shown that priming of therapeutic CD8(+) T cells in tumor vaccine-draining lymph nodes of mice vaccinated with GM-CSF secreting B16BL6 melanoma cells occurs independent of CD4 T cell help.
|
723 |
12391201
|
In this study, we examined the contribution of the major costimulatory molecules, CD40 ligand (CD40L), CD80, and CD86, in the priming of CD8(+) T cells.
|
724 |
12391201
|
Priming of therapeutic CD8(+) T cells by a GM-CSF-transduced tumor vaccine did not require CD40 and CD40L interactions, as therapeutic T cells could be generated from mice injected with anti-CD40L Ab and from CD40L knockout mice.
|
725 |
12391201
|
However, costimulation via either CD80 or CD86 was required, as therapeutic T cells could be generated from mice injected with either anti-CD80 or anti-CD86 Ab alone, but administration of both Abs completely inhibited the priming of therapeutic T cells.
|
726 |
12391201
|
Blocking experiments also identified that priming of therapeutic T cells in MHC class II-deficient mice required TNFR and IL-12 signaling, but signaling through CD40, lymphotoxin-betaR, or receptor activator of NF-kappaB was not essential.
|
727 |
12391201
|
Thus, cross-priming of therapeutic CD8(+) T cells by a tumor vaccine transduced with GM-CSF requires TNFR, IL-12, and CD28 signaling.

735 |
12393401
|
Using confocal microscopy we have confirmed our previous observation that heat-stressed apoptotic 12B1-D1 leukemia cells (BCR-ABL(+)) express HSP60 and HSP72 on their surface.
|
736 |
12393401
|
However, when stressed apoptotic 12B1-D1 cells were coincubated with immature dendritic cells for 24 hours, this resulted in greater up-regulation of costimulatory molecules (CD40, CD80, and CD86) on the surface of dendritic cells.
|
737 |
12439347
|
In general, DC phenotype was CD14(low), CD86(high), CD40(high), CD80(low), and CD83(low).
|
738 |
12445291
|
In natural immune responses CD4+ T helper (Th) cells, reactive with peptide antigens presented by major histocompatibility complex (MHC) class II molecules on dendritic cells (DC), can drive the maturation of DC that is required for induction of CD8+ cytolytic T-lymphocyte (CTL) immunity.
|
739 |
12445291
|
Proper induction, expansion and maintenance of CTL responses are achieved through delicate interactions between CD4+ T cells, DC and CD8+ T cells involving several ligand-receptor pairs.
|
740 |
12445291
|
Th cells to a large extent operate through up-regulation of CD40L, which then interacts with CD40 on DC to cause DC maturation.
|
741 |
12445291
|
Subsequent CTL induction by activated DC requires CD80/CD86 on the DC to interact with the CD28 costimulatory receptor on CD8+ T cells.
|
742 |
12445291
|
Alternative molecular triggers of DC activation that can support induction of powerful CTL responses include agonistic anti-CD40 antibody or ligands of Toll-like receptors (TLR) such as LPS (TLR4 ligand) or oligodeoxynucleotides containing CpG-motifs (TLR9 ligand).
|
743 |
12460195
|
Furthermore, after exposure to BCG-infected necrotic macrophages, DCs underwent phenotypic changes, including the up-regulation of maturation specific markers (major histocompatibility complex class II, CD40, CD80, and CD86) and the capacity to stimulate antigen-specific CD4+ T cells with higher efficiency than when they were directly infected with a similar number of bacteria.
|
744 |
12460195
|
Antigen presentation following phagocytosis of BCG-infected necrotic macrophages was demonstrated by their ability to stimulate in vitro proliferation and interferon-gamma production of antigen-specific CD4+ T cells.
|
745 |
12496156
|
Splenic dendritic cells (DCs) obtained from mice at 48 h after Listeria monocytogenes infection exhibited up-regulation of CD80 and produced higher titers of gamma interferon (IFN-gamma) and interleukin-12 (IL-12) than did DCs obtained from uninfected mice.
|
746 |
12496156
|
Infected DCs stimulated proliferation of naive CD4(+) and CD8(+) cells in vitro, suggesting that in vivo-infected DCs activate CD8(+) T cells, which are critical in acquired antilisterial resistance, as well as CD4(+) T cells.
|
747 |
12496156
|
These results suggest that DC-derived IL-12, but not IFN-gamma, may play a critical role in induction of acquired antilisterial resistance.
|
748 |
12512800
|
BMDC were generated from bone marrow precursor cells as described previously by culturing the cells in medium containing GM-CSF and IL-4.
|
749 |
12512800
|
Forty to fifty percent of both samples, frozen/thawed as well as fresh BMDC, exhibited characteristic DC morphology, and the DC obtained from the frozen/thawed samples expressed a similar level of MHC class I-, MHC class II-, CD80-, CD86-, CD11c-, CD11b-, CD54- and CD205-molecule as fresh DC.
|
750 |
12513792
|
The phenotype of DC was detected by FCM with CD1a, CD40, CD80, CD86, HLA-A, B, C and HLA-DR monoclonal antibodies.
|
751 |
12513792
|
The level of IL-12 and IFN-gamma in supernatant of DC culture was measured by ELISA.
|
752 |
12513792
|
A high expression of phenotypes was found in HL-60-DC and THP-1-DC stimulated by GM-CSF + IL-4 + TNF-gamma and K562-DC with GM-CSF + IL-4 + IL-12.
|
753 |

|
Fas ligand-expressing tumors induce tumor-specific protective immunity in the inoculated hosts but vaccination with the apoptotic tumors suppresses antitumor immunity.
|
754 |
12536202
|
The interaction between Fas and Fas ligand (FasL) is involved in the apoptotic death of a number of cells including lymphocytes.
|
755 |
12536202
|
Expression of the CD80 costimulatory molecule in tissues where UV-treated A11/FasL cells were inoculated was lower than the expression at an untreated A11/FasL-injected site.
|
756 |
12536236
|
The ability of acute myeloid leukaemia (AML) cells to acquire dendritic cell (DC)-like characteristics in vitro with a rapid culture method based either on the phorbol ester PMA or calcium ionophores has been studied in comparison to conventional AML-DC cultures with the cytokines granulocyte-macrophage colony-stimulating factor (GM-CSF), tumour necrosis factor-alpha (TNF-alpha), interleukin-3 (IL-3), SCF, FLT3-L and IL-4.
|
757 |
12536236
|
The most mature APC were generated by calcium ionophore A23187 plus IL-4, as evidenced by the higher expression of CD40, CD80, CD86 and HLA-DR.
|
758 |
12547595
|
Upon stimulation by infectious agent products, dendritic cells (DC) become activated, express high levels of class I and class II antigens, CD80, CD86 and CD83 and migrate to secondary lymphoid organs where they can prime naive CD4-helper and CD8-cytotoxic T-cells.
|
759 |
12547595
|
Cognate CD4(+) T-cell help mediated by CD40L along with DC stimulation with another T-cell effector molecule, termed lymphocyte activated gene-3 (LAG-3 or CD223, a ligand for MHC class II) have been shown to induce this maturation process.
|
760 |
12547595
|
Both CD40L and LAG-3 have been used as vaccine adjuvants to induce CTL and CD4 Th1 responses.
|
761 |
12547595
|
LAG-3Ig, unlike CD40L, induced an inflammatory signal in terms of IL-8 and MIP-1alpha/CCL3 production and, in contrast to LPS, induced production of chemokines (MDC/CCL22 and TARC/CCL17) known to direct the migration of maturing DC to lymph nodes.
|
762 |
12547595
|
In LAG-3-matured DC, surface expression of CCR5 (a receptor for MIP-1alpha/CCL3) was down-regulated and CCR7 (a receptor for MIP-3beta and SLC) was up-regulated.
|
763 |
12547595
|
However, LAG-3-matured, but not LPS- or CD40L-matured DC retained their capacity to migrate in chemotaxis chambers and to respond to MIP-1alpha.
|
764 |
12547598
|
Immature human DC were generated from peripheral blood monocytes cultured with GM-CSF and IL-4.
|
765 |
12547598
|
Uptake of antigen by DC and the degree of expression of the cell surface markers MHC class II, CD80, CD86 and the DC maturation marker CD83, was investigated by flow cytometry following incubation with liposomes or solution containing FITC-conjugated antigen.
|
766 |
12571630
|
Human and murine leukemic cells were transfected with retroviral vectors or plasmids carrying beta-galactosidase, GM-CSF or CD80 genes.

CD28 is an important costimulatory molecule for T cells, and it has been shown that cell surface expression of its ligands, CD80 and CD86, can enhance cellular immune responses against tumor cells, however, these tumor cells do not normally express the ligands.
|
768 |
12594842
|
Many new vaccines will be based upon soluble recombinant antigens, and in vaccination with these antigens CD80 and CD86 would normally be expressed on activated antigen-presenting cells and additional stimulation through CD28 would not be predicted to enhance responses further.
|
769 |
12594842
|
The mode of action of CD28 antibodies appears to be linked to their ability to signal through CD28, but not to bind the negative feedback regulatory antigen, CTLA-4.

Sera obtained before and after vaccination were analyzed for antibodies to tumor cell lysate, MUC1, HER2/neu and p53.
|
774 |
12616108
|
Eight of 24 patients made an antibody response to HER-2/neu, four of 24 to MUC1 and one of 24 to p53.
|
775 |
12616108
|
Although antibody production to a variety of tumor cell-associated antigens was detected our results suggest that a whole cell vaccine comprising a CD80-transfected allogeneic breast cancer cell line with adjuvant BCG or GM-CSF was not a reliable method to induce significant antibody responses in women with advanced breast cancer.

Members of the TNF ligand superfamily and the TNFR superfamily contribute to this costimulatory molecule signaling.
|
777 |
12626542
|
Coexpression of 4-1BBL in these E7-expressing DCs increased effector and memory CTL responses when they were used for immunization. 4-1BBL expression up-regulated CD80 and CD86 second signaling molecules in DCs.
|
778 |
12626542
|
We also report an additive effect of 4-1BBL and receptor activator of NF-kappa B/receptor activator of NF-kappa B ligand coexpression in E7-transduced DC immunogens on E7-directed effector and memory CTL responses and on MHC class II and CD80/86 expression in DCs.

|
OM-197 upregulated the expression of HLA-DR, CD80, CD86, CD83, CD40 and CD54 at the surface of myeloid DC naturally present in blood as well as of DC generated in vitro from monocytes using IL-4 and GM-CSF.
|
783 |
12639819
|
OM-197 also induced the release of IL-12 and TNF-alpha from DC.
|
784 |
12639819
|
Finally, DC incubated with OM-197 after pulsing with hepatitis B surface antigen (HBs Ag) induced in vitro expansion of IFN-gamma-secreting HBs Ag-specific CD4(+) T lymphocytes from naive individuals.
|
785 |
12654787
|
The immunopotentiating capacity of CT- and CTB-linked antigen was associated with both upregulated secretion of interleukin-1beta by the pulsed DC and increased expression of CD80 and CD86 on the DC surface.
|
786 |
12669245
|
In vitro culture of immature DC generated from adherent peripheral blood mononuclear cells (PBMC) using granulocyte macrophage-colony stimulating factor (GM-CSF) and interleukin-4 (IL-4) with OK432 at various doses (0.01 to 0.1 KE/ml) for 2 days resulted in increased cell surface expression of CD80, CD83, CD86 and ICAM-1 in a dose-dependent manner.
|
787 |
12669245
|
Assay of cytokine production in OK-DC after 2 days in culture revealed that OK432 was a strong inducer of IL-12 and interferon-gamma (IFN-gamma).
|
788 |
12672905
|
We showed that BCG could promote cord blood monocyte-derived DC maturation by up-regulation of CD80, CD83, CD86, CD40, and MHC class II molecules and down-regulation of mannose receptor.
|
789 |
12672905
|
BCG was able to induce similar levels of tumor necrosis factor-alpha and IL-10 but no bioactive IL-12p70 production from cord blood DCs as from adult blood DCs.
|
790 |
12672905
|
Both non-BCG-treated and BCG-treated cord blood DCs efficiently induced a high level of IL-10, medium level of interferon-gamma, but little IL-4 production by cord blood naïve CD4+ T cells.
|
791 |
12672905
|
Heat shock protein 65, a key component of BCG, had no effect on cord blood DC maturation in terms of CD86, MHC class II, and mannose receptor up-regulation.
|
792 |
12706680
|
This effect was due to activation of MHC class I-restricted CD8(+) T cells coupled with an increased secretion of proinflammatory cytokines IFN-gamma, TNF-alpha and IL-2.
|
793 |
12706680
|
Also, specific activation of dendritic cells was indicated by a two-three-fold upregulation of their costimulatory CD80 and MHC class II molecules.
|
794 |
12739069
|
High levels of Fas ligand and MHC class II in the absence of CD80 or CD86 expression and a decreased CD4+ T cell Infiltration, enables murine skin tumours to progress.
|
795 |
12739069
|
It has been hypothesized that tumour cells might evade immunological destruction by expressing Fas ligand (FasL), a molecule which induces apoptosis in Fas(+) target cells.
|
796 |
12739069
|
Detailed flow cytometric analysis was used to study tumour cell expression of FasL, Fas, CD80, CD86 and MHC class II.
|
797 |
12739069
|
We also analysed the percentage of apoptotic tumour cells in vivo using annexin V and correlated skin tumour progression with CD4 and CD8 T cell infiltration.
|
798 |
12739069
|
The percentage of progressor tumours expressing MHC II was significantly greater than regressor tumours, while neither tumour expressed CD80 or CD86 costimulatory molecules.
|
799 |
12739069
|
The results suggest that progression of skin tumours occurs if tumour cells express high levels of MHC II but not costimulatory molecules such as CD80 or CD86.

High levels of Fas ligand and MHC class II in the absence of CD80 or CD86 expression and a decreased CD4+ T cell Infiltration, enables murine skin tumours to progress.
|
813 |

|
It has been hypothesized that tumour cells might evade immunological destruction by expressing Fas ligand (FasL), a molecule which induces apoptosis in Fas(+) target cells.
|
814 |
12739069
|
Detailed flow cytometric analysis was used to study tumour cell expression of FasL, Fas, CD80, CD86 and MHC class II.
|
815 |

|
We also analysed the percentage of apoptotic tumour cells in vivo using annexin V and correlated skin tumour progression with CD4 and CD8 T cell infiltration.
|
816 |
12739069
|
The percentage of progressor tumours expressing MHC II was significantly greater than regressor tumours, while neither tumour expressed CD80 or CD86 costimulatory molecules.

Immature monocyte-derived dendritic cells (imMo-DCs) isolated from human peripheral blood monocytes stimulated with granulocyte-macrophage colony stimulating factor and interleukin-4 were exposed to maturation factors, i.e., lipopolysaccharide (LPS), tumor necrosis factor alpha (TNF-alpha) plus prostaglandin E2 (PGE2), and OK-432 for 2 days.
|
1120 |
14627128
|
OK-432 increased expression of activation- and maturation-related molecules such as HLA-DR, CD80, CD83, and CD86 in imMo-DCs at levels similar to that of TNF-alpha plus PGE2, and higher than that of LPS.
|
1121 |
14627128
|
Only OK-432 caused significant production of interleukin-12 (IL-12) p70 and interferon gamma (IFN-gamma) at both the mRNA and protein levels in imMo-DCs.
|
1122 |
14627128
|
Neutralizing antibody against IL-12 p70 blocked IFN-gamma secretion from OK-432-stimulated Mo-DCs.
|
1123 |
14627128
|
IL-12 p70 produced by OK-432-stimulated imMo-DCs induced secretion of IFN-gamma by CD4+ T cells.
|
1124 |
14627128
|
Both secretion of IL-12 p70 and IFN-gamma and activation of NF-kappaB induced by OK-432 were suppressed when imMo-DCs were pretreated with cytochalasin B.
|
1125 |
14627128
|
These results indicate that uptake of OK-432 by imMo-DCs is an early critical event for IL-12 p70 production and that NF-kappaB activation induced by OK-432 also contributes partially to IL-12 p70 production.

MHC class II and CD80 tumor cell-based vaccines are potent activators of type 1 CD4+ T lymphocytes provided they do not coexpress invariant chain.
|
1153 |
14730400
|
MHC class II(+)CD80+ vaccine cells were transfected with hen eggwhite lysozyme targeted to the cytosol, nuclei, mitochondria, or endoplasmic reticulum, and used as antigen-presenting cells to activate I-Ak-restricted, lysozyme-specific CD4+ 3A9 transgenic T cells.
|
1154 |
14730400
|
Regardless of the cellular location of lysozyme, the vaccines stimulated release of high levels of IFN-gamma and IL-2.
|
1155 |
14730400
|
If the vaccines coexpressed the MHC class II accessory molecule invariant chain, then IFN-gamma and IL-2 release was significantly reduced.
|
1156 |
14730400
|
These studies demonstrate that in the absence of invariant chain the MHC class II and CD80 tumor cell vaccines (1) function as antigen-presenting cells to activate naïve, tumor-specific CD4+ cells to endogenously synthesized tumor antigens; (2) polarize the activated CD4+ T cells toward a type 1 response; and (3) present epitopes derived from varied subcellular locales.

These studies demonstrate that in the absence of invariant chain the MHC class II and CD80 tumor cell vaccines (1) function as antigen-presenting cells to activate naïve, tumor-specific CD4+ cells to endogenously synthesized tumor antigens; (2) polarize the activated CD4+ T cells toward a type 1 response; and (3) present epitopes derived from varied subcellular locales.

BCG-CWS was capable of activating DCs ex vivo by the criteria of CD80/CD86 up-regulation and cytokine (interleukin-12, tumor necrosis factor-alpha) induction.
|

|
Dendritic cells generated in the presence of GM-CSF plus IL-15 prime potent CD8+ Tc1 responses in vivo.
|
1169 |
14971031
|
DC progenitors can be stimulated to differentiate into immature DC by various growth factors, including GM-CSF and IL-4.
|
1170 |
14971031
|
Here we show that IL-15, in combination with GM-CSF, is a growth factor for murine DC.
|
1171 |
14971031
|
Murine bone marrow cells, depleted of T cells, B cells, I-A+ cells and Gr-1+ granulocytes, and cultured in the presence of GM-CSF plus IL-15 (IL-15 DC), yielded DC expressing high levels of CD11c and MHC class II molecules, as well as CD11b.
|
1172 |
14971031
|
These cells expressed significant levels of CD40, CD80 and CD86, and could stimulate allogeneic CD4+ T cells efficiently.
|
1173 |
14971031
|
Interestingly, IL-15 DC were far superior to DC generated with GM-CSF plus IL-4 in stimulating allogeneic CD8+ T cells in vitro.
|
1174 |
14971031
|
Consistent with this, IL-15 DC induced much more potent antigen-specific CD8+ T cell responses with high levels of Th1 cytokines in vivo, compared to DC generated with GM-CSF plus IL-4, or with GM-CSF plus TGF-beta, or with GM-CSF alone.
|
1175 |
14971031
|
Together, these data suggest that IL-15 promotes the development of DC, which induce potent Th1 and Tc1 responses in vivo.

Retroviral transduction of acute myeloid leukaemia-derived dendritic cells with OX40 ligand augments their antigen presenting activity.
|
1177 |
14984494
|
In the present study, we examined whether the transduction of leukaemia-DCs with OX40 ligand (OX40L), a member of the tumour necrosis factor (TNF) family, resulted in augmentation of their antigen presenting activity.
|
1178 |
14984494
|
Fresh leukaemic cells from five patients with acute myeloid leukaemia (AML) were isolated and retrovirally transduced with OX40L during the culture with a combination of cytokines from stem cell factor, fms-like tyrosine kinase (Flt)-3 ligand, granulocyte-macrophage colony stimulating factor (GM-CSF), interleukin-4 (IL-4) and TNF-alpha.
|
1179 |
14984494
|
After 7 d, the majority of cells showed DC-like morphology, and expressed higher levels of CD80, CD86 and HLA-DR than fresh leukaemic cells.
|
1180 |
14984494
|
Co-culture of allogeneic CD4+ T cells with OX40L-transduced leukaemia-DCs was superior in the generation of interferon (IFN)-gamma producing CD4+ T cells and in production of IFN-gamma.
|
1181 |

|
In vitro stimulation of immature murine DC with MALP-2 resulted in the induction of maturation with up-regulated expression of MHC class II, costimulatory (CD80, CD86) and adhesion (CD40, CD54) molecules.
|
1182 |
14991620
|
MALP-2 also enhances the secretion of cytokines (IL-1alpha, IL-6 and IL-12), and increases DC stimulatory activity on naive and antigen-specific T cells.
|
1183 |
14991620
|
Further studies demonstrated that MALP-2 treatment of DC results in a dose-dependent shift from the protein pattern of proteasomes to immunoproteasomes (up-regulation of LMP2, LMP7 and MECL1), which correlates with an increased proteolytic activity.
|
1184 |

We demonstrated previously that the vaccine cells present tumor peptides via the endogenous antigen presentation pathway to activate CD4(+) and CD8(+) T cells.

|
To obtain MHC class II(+)CD80(+)Ii(-) human tumor cells, we developed retroviruses encoding HLA-DR and CD80.
|
1186 |
14996751
|
SUM159PT mammary carcinoma and Mel 202 ocular melanoma cells transduced with the retroviruses DRB1/CD80 express high levels of DRB0101 and CD80 on the cell surface in the absence of Ii.
|
1187 |
14996751
|
Irradiated SUM159PT/DR1/CD80 vaccines stimulate proliferation of non-HLA-DRB0101 peripheral blood mononuclear cells and present an exogenous DR1-restricted tetanus toxoid (TT) peptide, indicating that the transduced DRB0101 is functional.
|
1188 |
14996751
|
SUM159PT/DR1/CD80 vaccines were further transduced with a retrovirus encoding the TT fragment C gene, as a model tumor antigen.
|
1189 |
14996751
|
Depletion and antibody blocking experiments confirm that MHC class II-restricted, endogenously synthesized epitopes are presented to CD4(+) T cells.
|
1190 |
14996751
|
Therefore, the MHC class II vaccines are efficient antigen-presenting cells that activate tumor-specific MHC class II-restricted, CD4(+) T lymphocytes, and they are a novel and potential immunotherapeutic for metastatic cancers.

|
The vaccine used mature DCs (CD1a+++, CD40++, CD80++, CD83+, and CD86+++) generated from peripheral blood monocytes in the presence of GM-CSF and IL-4.
|
1213 |
14999431
|
After 7 days, DCs were matured with a defined cocktail of cytokines (IL-1+IL-6+TNF-alpha+PGE2) and simultaneously pulsed with lysates of heterologous melanoma cell lines, for 2 days.

Nasal Flt3 ligand cDNA elicits CD11c+CD8+ dendritic cells for enhanced mucosal immunity.
|
1215 |
15004163
|
In addition, significant levels of OVA-specific CD4+ T cell proliferative responses and OVA-induced IL-4 and IL-2 production were noted in spleen and cervical lymph nodes.
|
1216 |
15004163
|
Further, marked increases in FL protein occurred in the nasal lamina propria and submandibular glands and the frequencies of CD11c+CD8+ dendritic cells (DCs) significantly increased in the mucosal tissues.
|
1217 |
15004163
|
Moreover, these DCs expressed high levels of CD40, CD80, CD86, and MHC class II molecules.
|
1218 |
15011756
|
According to the research group of Shortman, experimental results suggest a "dual" DC differentiation model, demonstrating the existence of both myeloid-derived (with characteristic IF: CD11b+, CD11c+, CD8alpha- and DEC205+) and lymphoid-derived DCs (showing CD11b- CD11c-, CD8alpha+ and DEC205+ IF).
|
1219 |
15011756
|
Most of the DCs express immunocytochemically detectable antigens like: S-100, CD1a, CD40 receptor, adhesion molecules (ICAM-1 or CD54, LFA-1 and LFA-3), integrins (CD11a, CD11c and CD18), CD45, CD54, co-stimulatory molecules (B7-1 or CD80, B7-2 or CD86), F418, MHC class I and II and DEC-205, multilectin receptor, immunostimulatory cytokine (IL-12) and, of course, Fc and complement receptors.
|
1220 |
15019294
|
CD14-positive cells cultured in the presence of PSK significantly increased the expression of HLA class II antigen and CD40; significantly increased the number and expression of CD80-, CD86- and CD83-positive cells; decreased Fluorescein isothiocyanate (FITC)-dextran uptake, augmented IL-12 production; augmented the allogeneic mixed lymphocyte reaction; and induced antigen-specific cytotoxicity.
|
1221 |
15075365
|
Flt3L-mobilized DCs exhibited slightly increased CD80/CD86 expression but typically still that of immature DCs and were resilient to freeze-thawing.
|
1222 |
15075365
|
Overnight culture activated the cells, up-regulating CD80/CD86 expression as well as interleukin-12 release, typically being boosted by CD40L.

1225 |
15083197
|
We constructed a recombinant adenovirus expressing the full-length cDNA of HCA661 gene and then transduced immature DCs, which had been generated with GM-CSF and IL-4 from peripheral blood mononuclear cell of HLA-A2(+) healthy donors.
|
1226 |
15083197
|
The resulting adenovirus-transduced DCs differentiated in the presence of monocyte-conditioned medium and poly [I] : poly [C], expressing the surface markers of mature DCs, including CD83, CD80, CD86 and HLA-DR.
|
1227 |
15085174
|
In both cases, antigen-specific CD4+ and CD8+ T cells were detectable after vaccination.
|
1228 |
15085174
|
Analysis of DC from Flt-3L-treated mice revealed an immature phenotype with low or absent expression levels of CD80, CD86 and CD40.
|
1229 |
15099757
|
Dendritic cell-like cells (Mo-DCs) generated from peripheral blood monocytes with interleukin-4 (IL-4) and granulocyte-macrophage colony-stimulating factor (GM-CSF) have been used as tools to treat cancer patients (DC-vaccines).
|
1230 |
15099757
|
In addition, we collected Mo-DCs from the collagen gels by collagenase treatment and analyzed the expression of antigen presentation-related molecules such as HLA-DR, CD80, CD83, and CD86 on Mo-DCs.
|
1231 |
15099760
|
The ingestion of MS did not change the cell surface expression of CD80, CD83, CD86 and HLA-DR of immature and mature DC, suggesting that MS uptake did not induce DC maturation but that maturation by cytokines or LPS was unaltered in the presence of MS.
|
1232 |
15099760
|
Furthermore, MS-loaded mature MoDC expressed normal levels of the chemokine receptor CCR7 and migrated as efficiently towards CCL19 or CCL21 as unloaded MoDC.
|
1233 |
15099760
|
DC viability and the secretion of TNF-alpha and IL-12 was not significantly changed by MS loading.
|
1234 |
15103504
|
In these studies, we demonstrate that exogenous soluble LIGHT or soluble CD40 ligand (CD40L) can promote monocyte-derived dendritic cell maturation in vitro by the up-regulation of CD86, CD80, CD83, and HLA-DR antigen expression.
|
1235 |
15103504
|
However, upon induction of maturation by LIGHT or CD40L, the expression of costimulatory and HLA-DR molecules is comparable between DCs from MDS and normal subjects.
|
1236 |
15103504
|
Exogenous LIGHT- and CD40L-stimulated mature DCs (mDCs) also displayed increased antigen presentation to autologous T lymphocytes (tetanus toxin) or allogeneic T lymphocytes in mixed lymphocyte reactions.
|
1237 |
15103504
|
DCs matured by LIGHT showed increased secretion of IL-6, IL-12p75, and TNF-alpha, but not IL-1beta.
|
1238 |
15103504
|
We conclude that both LIGHT and CD40L are immunoregulating factors that induce monocyte-derived iDCs from MDS patients to undergo maturation resulting in increased antigen presentation and T-cell activation.
|
1239 |
15120002
|
The in vivo adjuvant properties of N. meningitidis wild-type and mutant LPS was found to correlate with induction of co-stimulatory molecules, in particular CD80 and CD40, and with IL-12 production by LPS-stimulated bone marrow-derived BALB/c dendritic cells in vitro.
|
1240 |
15122754
|
HCs upregulate surface expression of major histocompatibility complex (MHC) class I molecules and CD1d but not MHC class II molecules Qa-1, CD80, CD86, CD54, or CD95; in addition, they expressed/secreted interleukin (IL)-10 and IL-4 but not IL-1, IL-6, IL-13, interferon (IFN)-gamma, tumor necrosis factor (TNF), IL-4, or IL-27 (i.e., they acquire the HC* phenotype).
|
1241 |
15122754
|
HCs* (but not HCs) induced specific activation, proliferation, and IFN-gamma, TNF, and IL-13 release of cocultured naïve CD8(+) T cells.
|
1242 |
15122754
|
Only recently activated CD8(+) T blasts (but not recently activated CD4(+) T blasts or activated cells of the innate immune system, including natural killer T [NKT] cells) induced the HC* phenotype that is prominent from day 10 to day 20 postvaccination (i.e., time points at which peak numbers of recently primed CD8(+) T blasts are found in the liver).
|
1243 |

|
Vaccination with membranes modified by protein transfer to express GPI-linked B7.1 (CD80), a costimulatory adhesion molecule, induces protective immunity in mice and allogeneic antitumor T-cell proliferation in humans in vitro.
|
1244 |
15193398
|
We also observed that at the molecular level Tomatine required both CD80 and CD86 costimulation to engender antigen-specific cellular immunity.
|
1245 |
15203918
|
CD11c (approximately 90%), MHC-II (approximately 70%), CD86 (approximately 20%), CD83 (approximately 5%), CD80 (approximately 40%), CD40 (approximately 40%), and CCR7 (approximately 5%).
|
1246 |
15204101
|
The performance of DCs in mixed lymphocyte reaction correlated significantly (p = 0.005) with the CD83 expression but not with the CD80, CD86, HLA-DR, CD1a, and CD1c expression.
|
1247 |
15207780
|
Vaccination with OVA-CT-pulsed DC concurrently induced strong CTL in vitro activity and anti-E.G7 tumor protection in vivo in WT, NK-depleted and CD4-deficient mice as well as in IL-12-/- and IFN-gamma-/- mice but not in CD8-deficient mice.
|
1248 |
15207780
|
Importantly, activation of CTL by OVA-CT-pulsed DC was dependent on CT-induced activation of adenylate cyclase and increased cAMP production by DC associated with increased expression of MHC class I and co-stimulatory molecules (CD80, CD86 and CD40).
|
1249 |
15214052
|
In this study, we demonstrate that pretreatment of monocytes with human HSP60 results in a suppression of TNF-alpha production on restimulation with HSP60.
|
1250 |
15214052
|
Furthermore, desensitization with HSP60 inhibits TNF-alpha expression in these cells in response to LPS stimulation, thereby inducing "cross-tolerance".
|
1251 |
15214052
|
In contrast to TNF-alpha suppression, IL-1beta expression was augmented in HSP60-pretreated monocytes on restimulation, while being suppressed in THP-1 cells.
|
1252 |
15214052
|
Addition of an anti-IL-10 neutralizing antibody had no significant effect on HSP60- or LPS-induced tolerance.HSP60 priming of monocytes also results in significant down-regulation of HLA-DR, CD86 and Toll-like receptor 4 expression, but minimally up-regulates CD80 expression, similar to that previously reported with LPS.
|
1253 |
15214052
|
By identifying a previously unrecognized "tolerizing" effect of extended exposure to autologous HSP60 on the innate immune system, as opposed to its recently identified pro-inflammatory stimulatory capacity, this study highlights a further level of complexity of our understanding of the biological activities of HSP.
|
1254 |
15242811
|
Human monocytes were cultured with GM-CSF and IL-4 for 6 days, followed by another 2 days in the presence of M1, M4 or TNF-alpha as a maturation stimulus.
|
1255 |
15242811
|
Stimulation with 20 microM of M1 or M4 increased expression level of CD80, CD83 and CD86 as expressed by mean fluorescence intensity (MFI) and decreased endocytic activity.
|
1256 |
15242811
|
In CTL assay, the production of IFN-gamma and 51Cr release on M4-primed mature DCs was more augmented than of immature DCs or TNF-alpha-primed mature DCs.
|
1257 |
15254744
|
OK432 and PSK were examined in vitro, and compared with lipopolysaccharide (LPS) and a cytokine cocktail (IL-1beta, TNF-alpha, IL-6 and PGE2).
|
1258 |
15254744
|
In the immunophenotypical analysis, the expression of CD80 and CD83 of DCs stimulated with OK-432 increased significantly compared with PSK and medium, and this up-regulation was the same as levels of DCs stimulated with cytokine cocktail.
|
1259 |
15254744
|
DCs stimulated with OK-432 showed significantly higher production of IL-12 and Th1-type cytokines (IL-2 and IFN-gamma) compared with DCs stimulated with LPS or cytokine cocktail.

There are two principle subsets of dendritic cells (DCs); CD11c(+)CD123(-) myeloid DCs (MDCs) and CD11c(-)CD123(+) plasmacytoid DCs (PDCs).
|
1261 |
15265893
|
Using lineage (Lin) markers to exclude non-DCs, Lin(-)HLA-DR(+)CD11c(+)CD123(-) MDCs and Lin(-)HLA-DR(+)CD11c(-)CD123(+) PDCs were identified in the blood of uninfected macaques and healthy macaques infected with SIV or simian-human immunodeficiency virus.
|
1262 |
15265893
|
Overnight culture of DC-enriched Lin-depleted cells increased CD80 and CD86 expression.
|
1263 |
15265893
|
IL-12 production and CD80/CD86 expression by MDC/PDC mixtures was further enhanced by CD40L and ISS-ODN treatment.
|
1264 |
15265893
|
A CpG-B ISS-ODN increased CD80/CD86 expression by PDCs, but resulted in little IFN-alpha secretion unless IL-3 was added.
|
1265 |
15265893
|
In contrast, a CpG-C ISS-ODN and aldrithiol-2-inactivated (AT-2) SIV induced considerable PDC activation and IFN-alpha release without needing exogenous IL-3.
|
1266 |
15265893
|
The CpG-C ISS-ODN also stimulated IL-12 release (unlike AT-2 SIV) and augmented DC immunostimulatory activity, increasing SIV-specific T cell IFN-gamma production induced by AT-2 SIV-presenting MDC/PDC-enriched mixtures.
|
1267 |
15265893
|
These data highlight the functional capacities of MDCs and PDCs in naive as well as healthy, infected macaques, revealing a promising CpG-C ISS-ODN-driven DC activation strategy that boosts immune function to augment preventative and therapeutic vaccine efficacy.

Using lineage (Lin) markers to exclude non-DCs, Lin(-)HLA-DR(+)CD11c(+)CD123(-) MDCs and Lin(-)HLA-DR(+)CD11c(-)CD123(+) PDCs were identified in the blood of uninfected macaques and healthy macaques infected with SIV or simian-human immunodeficiency virus.

Overnight culture of DC-enriched Lin-depleted cells increased CD80 and CD86 expression.
|
1279 |
15265893
|
IL-12 production and CD80/CD86 expression by MDC/PDC mixtures was further enhanced by CD40L and ISS-ODN treatment.
|
1280 |
15265893
|
A CpG-B ISS-ODN increased CD80/CD86 expression by PDCs, but resulted in little IFN-alpha secretion unless IL-3 was added.
|
1281 |
15265893
|
In contrast, a CpG-C ISS-ODN and aldrithiol-2-inactivated (AT-2) SIV induced considerable PDC activation and IFN-alpha release without needing exogenous IL-3.
|
1282 |
15265893
|
The CpG-C ISS-ODN also stimulated IL-12 release (unlike AT-2 SIV) and augmented DC immunostimulatory activity, increasing SIV-specific T cell IFN-gamma production induced by AT-2 SIV-presenting MDC/PDC-enriched mixtures.
|
1283 |
15265893
|
These data highlight the functional capacities of MDCs and PDCs in naive as well as healthy, infected macaques, revealing a promising CpG-C ISS-ODN-driven DC activation strategy that boosts immune function to augment preventative and therapeutic vaccine efficacy.

Nasal immunization of mice with ovalbumin (OVA) plus the Stx1-B or mStx1 induced OVA-specific serum IgG and mucosal IgA responses.
|
1285 |
15315856
|
IgG subclass analysis revealed that mStx1 and Stx1-B as mucosal adjuvants supported Ag-specific IgG1 followed by IgG2b Abs.
|
1286 |
15315856
|
The co-administration of either mStx1 or Stx1-B with OVA enhanced the production of IL-4, IL-5, IL-6 and IL-10 with low IFN-gamma, by OVA-specific CD4+ T cells.
|
1287 |
15315856
|
To better elucidate the mechanisms underlying mStx1's and Stx1-B's adjuvant activity, we next sought to examine whether or not dendritic cells (DC) residing in the nasopharyngeal-associated lymphoreticular tissue (NALT) were activated by nasal administration of Stx1-B or mStx1.
|
1288 |
15315856
|
We found that mice nasally administered with Stx1-B or mStx1 showed an up-regulation in the expression of CD80, CD86 and especially CD40 on NALT DCs.
|
1289 |
15315856
|
Taken together, these results suggest that non-toxic Stx derivatives could be effective mucosal adjuvants for the induction of Th2-type, CD4+ T cell mediated, antigen-specific mucosal IgA and systemic IgG Ab responses, and that they likely owe their adjuvant activity to the up-regulation of co-stimulatory molecules including CD80, CD86 and CD40 on NALT DCs.

TgHSP70 induced the maturation of human monocyte-derived dendritic cells as determined by increased levels of surface markers, namely, CD40, CD80, CD86, and HLA-DR.
|
1297 |
15336548
|
TgHSP70 also stimulated extracellular signal-regulated kinase and p38 kinase pathways in DCs, and TgHSP70-induced IL-12 production was inhibited by SB203580 but not by PD98059, thus indicating the role of p38 kinase in the maturation of DCs by TgHSP70.

Amplification of the lytic potential of effector/memory CD8+ cells by vector-based enhancement of ICAM-1 (CD54) in target cells: implications for intratumoral vaccine therapy.
|
1299 |
15354200
|
We demonstrated that enhanced expression of the costimulatory molecules CD80, CD54 and CD48 (designated rF-TRICOM) on target cells, as delivered via a recombinant fowlpox vector, results in an increased state of stimulation of CD8+ T cells, and consequent increased lysis of target cells.
|
1300 |
15354200
|
CTL studies in conjunction with antibody-blocking studies demonstrated that the enhanced effector activity of these CD8+ T cells is mediated mainly through CD54.
|
1301 |
15354200
|
The interaction of T cells with target cells that overexpress costimulatory molecules upon infection with rF-TRICOM leads to enhanced signaling through Lck, ZAP70, and STAT-1 in CD8+ T cells and heightened lytic activity of CD8+ cells through the formation of a greater number of immunological synapses.
|

|
Here, we show that BCG infection of monocytes causes their differentiation into mature dendritic cells (DCs) lacking CD1 molecules expression, coupled with suboptimal up-regulation of HLA class II, CD80 and CD40 molecules and a marked unresponsiveness to lipopolysaccharide stimulation.

A CD80-transfected human breast cancer cell variant induces HER-2/neu-specific T cells in HLA-A*02-matched situations in vitro as well as in vivo.
|
1304 |
15365776
|
Using CD80+ KS breast cancer cells and human leukocyte antigen (HLA)-A*02-matched peripheral blood mononuclear cells (PBMCs) of breast cancer patients in allogeneic mixed lymphocyte-tumor cell cultures (MLTCs), it was possible to isolate HLA-A*02-restricted cytotoxic T cells (CTLs).
|
1305 |
15365776
|
KS breast cancer cells were demonstrated to express already known TAAs such as CEA, MUC-1, MAGE-1, MAGE-2, and MAGE-3.
|
1306 |
15365776
|
To further improve antigenicity, HER-2/neu was added to this panel as a marker antigen known to elicit HLA-A*02-restricted CTLs in patients with breast cancer.
|
1307 |
15365776
|
Thus, the antigen-processing and antigen-presentation capacity of KS cells was further demonstrated by the stimulation of HER-2/neu-specific CD8+ T cells in PBMCs of breast cancer patients in vitro.
|
1308 |
15365776
|
These results gave a good rationale for a phase I/II trial, where the CD80+ HER-2/neu-overexpressing KS variant is actually used as a cellular vaccine in patients with metastatic breast cancer.
|
1309 |
15365776
|
As a proof of principle, we present data from two patients where a significant increase of interferon-gamma (IFN-gamma) release was detected when postvaccination PBMCs were stimulated by allogeneic vaccine cells as well as by HLA-A*02-restricted HER-2/neu epitopes.

We found that lipopolysaccharides (LPS), unmethylated CpG motifs (CpG ODN) and sorbitol enhanced CVLP-induced stimulation of C57BL/6 mouse BMDCs as revealed by increased levels of CD40, CD80, MHC II and CD54 at the cell surface.

|
After culture with clinical grade GM-CSF and IL-13, OM-197 at 20 microg/ml efficiently induced CD83+ Mo-DC.
|
1326 |
15481142
|
In comparison to immature Mo-DC that were derived by culture with GM-CSF and IL-13 only, CD40, CD80, CD86, HLA-ABC and HLA-DR molecules were up-regulated upon OM-197 or LPS treatment similarly.
|
1327 |
15481142
|
No significant difference in IFN-gamma quantification was shown between naive CD4+ T cells stimulated by LPS- or OM-197-Mo-DC suggesting that OM-197-Mo-DC can drive naive T cells towards a Th1 response profile that was mainly independent of IL-12 secretion.

Porin of Shigella dysenteriae type 1 increased the mRNA levels for Toll-like receptor (TLR) 2 and TLR6 by 1.5- and 2.9-fold respectively, of peritoneal cavity B-1a and B-1b cells, implicating that coexpression of TLR2 and TLR6 is essential as a combinatorial repertoire for recognition of porin by the B-1 cells.
|
1329 |
15482852
|
Among the two key TLRs, TLR2 and TLR4, which are primarily responsible for recognizing majority of the bacterial products, TLR2 and not TLR4, participates in porin recognition.
|
1330 |
15482852
|
TLR2 got increased on both the B-1 cell populations whereas the TLR4 expression remained unaffected.
|
1331 |
15482852
|
Both of the B-1 cell populations expressed strongly the mRNA for NF-kappaB in the presence of porin, that was 2.4-fold more than untreated control, conforming to the earlier finding that coexpression of TLR2 and TLR6, resulted in robust NF-kappaB activation for signaling.
|
1332 |
15482852
|
CD80 expression got enhanced on the B-1a cells whereas CD86 got solely expressed on B-1b cells.
|
1333 |
15482852
|
The porin-mediated induction of IgA was augmented by interleukin-6 on B-1a and B-1b cells, by 2.4- and 2.6-fold, respectively.

Incubation of immature human PBMC-derived DCs with SHIV VLPs for 48 h resulted in the significant up-regulation of CD40, CD80, CD83, CD54, CD86, HLA-A, B, C and HLA-DR, DP, DQ molecules on activated DC CD11c+ subpopulations.

The co-administration of costimulatory molecules CD80 (B7-1), CD86 (B7-2) and CD154 (CD40L) has been shown to enhance immune responses in several murine models.

15542201

In these studies, we demonstrate that the co-administration of CD80 and CD86, but not CD154, to an existing candidate subunit DNA vaccine (ESAT-6) against bovine tuberculosis, enhances protection after aerosol challenge with virulent Mycobacterium bovis.
|
1339 |
15542201
|
Two independent trials were conducted in cattle to determine the adjuvant effect of encoded antigen + CD80/CD86 and directly compare the adjuvant activities of CD80/CD86 to those of CD154.
|
1340 |
15542201
|
Co-administration of either CD80/CD86 or CD154 enhanced ESAT-6-specific IFN-gamma responses as compared to animals vaccinated with ESAT-6 DNA alone.
|
1341 |
15542201
|
However, following aerosol challenge, only animals vaccinated with CD80/CD86 possessed decreased pathology of the lungs and associated lymph nodes, as measured by gross examination, radiographic lesion morphometry and bacterial recovery.
|
1342 |
15542201

Collectively, these results demonstrate that the co-administration of costimulatory molecules with a protective antigen target enhances bovine immune responses to DNA vaccination, and that CD80/CD86 is superior to CD154 in augmenting DNA vaccine-induced protection in experimental bovine tuberculosis.

Concomitantly with HTLV-I-expression, these ATL cells expressed co-stimulatory molecules such as CD80, CD86 and OX40, and showed elevated levels of antigenicity against allogeneic T cells and HTLV-I Tax-specific cytotoxic T-lymphocytes (CTL).

The inactivation of the MAPK pathway in both macrophages and dendritic cells leads to inhibition of proinflammatory cytokine secretion, downregulation of costimulatory molecules such as CD80 and CD86, and ineffective T cell priming.

This study investigated the effects of the common gamma chain-binding cytokines, interleukin (IL)-2 and IL-15, on costimulatory properties of primary CLL cells from 51 patients.
|
1388 |
15566356
|
IL-2 improved the ability of CLL cells to stimulate T cell proliferation and increased the expression of costimulatory molecules (particularly CD80) in a dose-dependent fashion, especially in CLL cells with weak expression of CD38.
|
1389 |
15566356
|
CD80 and CD86 induction by IL-2 were positively regulated through the mitogen-activated protein kinase pathway, while CD86 expression was negatively regulated through Janus kinase pathways.
|
1390 |
15566356
|
However, further activation with protein kinase C agonists was required for IL-2 activated CLL cells to stimulate autologous T cells sufficiently to clear bystander CLL cells from mixed lymphocyte responses.
|
1391 |
15566356
|
These results suggest a role for IL-2, or IL-15, in immunotherapeutic strategies for CLL.

IL-2/B7.1 (CD80) fusagene transduction of AML blasts by a self-inactivating lentiviral vector stimulates T cell responses in vitro: a strategy to generate whole cell vaccines for AML.
|
1398 |
15585413
|
Specifically, syngeneic tumor cells genetically modified to express B7.1 (CD80) have been shown to induce rejection of previously established murine solid tumors, and transduction with IL-2 can further increase survival.

LTK63 treatment increased the pathogen-specific IgA response in the nasal mucosa and simultaneously decreased inflammatory cytokine production (IFN-gamma and TNF-alpha) after infection.
|
1403 |
15585869
|
The number of activated CD8(+)CD44(+) T cells and the respiratory syncytial virus- or influenza-specific CD8-proliferative responses increased, although the total inflammatory infiltrate was reduced.

Exposure to proteoliposomes from serogroup B Neisseria meningitidis (PL) induced up-regulation of MHC-II, MHC-I, CD40, CD80 and CD86 expression on the surface of murine bone marrow-derived dendritic cells (DC).
|
1405 |
15652674
|
CD40, CD80 and CD86 were up-regulated on bone marrow-derived macrophages (MPhi) upon stimulation with PL.
|
1406 |
15652674
|
A small increase in the expression of MHC-II, CD40 and CD86, as well as production of IL12(p70), was observed on the cell surface of DC, but not MPhi from LPS-non-responder C3H/HeJ after exposure to PL.
|
1407 |
15652674
|
DC, but not MPhi, incubated with PL containing ovalbumin (PL-OVA) presented OVA-specific peptides to CD4+ and CD8+ OVA-specific T-cell hybridomas.
|
1408 |
15652674
|
The work also shows the potential of PL as a general system to deliver antigens to DC for presentation to CD4+ and CD8+ T-cells.

|
Using one CpG-ODN, DSP30, we observed that it could upregulate not only Toll-like receptor 9 (TLR9) mRNA expression in activated B-cells, but also the early expression of CD69 followed by the sequential expression of CD80, CD86 and the nuclear factor (NF)-kappaB pathway.
|
1415 |
15653438
|
Furthermore, mRNA expression of certain B-cell-derived cytokines was influenced by exposure to DSP30, with a strong upregulation of interleukin 6 (IL-6) and downregulation of IL1-beta.
|
1416 |
15653438
|
Stimulation of B-cells, co-stimulated with IL-2, IL-10 and soluble CD40 ligand (sCD40L) with different CpG-ODNs, had differing effects on the terminal differentiation in vitro of B-cells into immunoglobulin-secreting cells.

|
Dendritic cells derived from metastatic cancer patients vaccinated with allogeneic dendritic cell-autologous tumor cell hybrids express more CD86 and induce higher levels of interferon-gamma in mixed lymphocyte reactions.
|
1418 |
15693140
|
Mononuclear cells were isolated from patients' peripheral blood by density gradient centrifugation, and adherent cells were cultured in medium containing GM-CSF plus IL-4 and, after 5 days, TNF-alpha.
|
1419 |
15693140
|
After 2 more days, Mo-DCs were harvested and their CD80, CD86, and CD83 expression was assessed by flow cytometry.
|
1420 |
15693140
|
They were also used as stimulators in mixed lymphocyte reactions (MLR), where IFN-gamma production was measured by ELISA.
|
1421 |
15693140
|
Mo-DCs from unvaccinated patients expressed significantly lower levels of CD86, and tended to express lower levels of CD83 than Mo-DCs from healthy donors.
|
1422 |
15693140
|
However, Mo-DCs generated after hybrid cell vaccination presented increased expression of the same markers and induced significantly higher levels of IFN-gamma in MLR.
|
1423 |
15710900
|
Lactobacillus-exposed MDCs up-regulated HLA-DR, CD83, CD40, CD80, and CD86 and secreted high levels of IL-12 and IL-18, but not IL-10.
|
1424 |
15710900
|
IL-12 was sustained in MDCs exposed to all three Lactobacillus species in the presence of LPS from Escherichia coli, whereas LPS-induced IL-10 was greatly inhibited.
|
1425 |
15710900
|
MDCs activated with lactobacilli clearly skewed CD4(+) and CD8(+) T cells to T helper 1 and Tc1 polarization, as evidenced by secretion of IFN-gamma, but not IL-4 or IL-13.
|
1426 |
15725957
|
Co-incubation of immature DCs with ghosts resulted in decreased expression of CD1a, CD80, and CD83 molecules, while addition of maturation mix (TNF-alpha, IL-1 beta, IL-6, and PGE2) to the cultures enhanced expression of these molecules.
|
1427 |
15725957
|
No marked changes were observed in the expression of the CD11c, CD40, and CD86 surface molecules.
|
1428 |
15731055
|
DC exposed to live EBs acquired a mature DC morphology; expressed high levels of major histocompatibility complex (MHC) class II, CD80, CD86, CD40, and ICAM-1; produced elevated amounts of interleukin-12 and tumor necrosis factor alpha; and were efficiently recognized by Chlamydia-specific CD4+ T cells.
|
1429 |
15731055
|
In contrast, UV-EB-pulsed DC expressed low levels of CD40 and CD86 but displayed high levels of MHC class II, ICAM-1, and CD80; secreted low levels of proinflammatory cytokines; and exhibited reduced recognition by Chlamydia-specific CD4+ T cells.

|
The intrinsic cellular activities of the lipopeptide analogues incorporated into liposomes were monitored, in vitro, by measuring the up-regulation of the cell-surface markers CD80, CD83, CD86 and HLA-DR.
|
1433 |
15782312
|
A decrease in the proportions of the major BDCA-1+, CD1b myeloid dendritic cell subset and a reciprocal increase in the minor BDCA-3+ dendritic cell subsets resulted at 3-4 days, then their levels returned to normal.
|
1434 |
15782312
|
No significant changes in percentages of CD86 and CD80 APCs or CD4+, CD25+ T-cells were documented.
|
1435 |
15787742
|
Murine bone marrow-derived dendritic cells (DC) can be generated by culture in the presence of granulocyte/macrophage colony-stimulating factor (GM-CSF) alone or GM-CSF in conjunction with interleukin-4 (IL-4).
|
1436 |
15787742
|
Also, the four culture conditions generated CD11c+ DC with comparable levels of major histocompatibility complex (MHC) class II, CD40, CD80 and CD86 expression, with the exception of cells cultured under serum-free conditions in the absence of IL-4, which displayed suboptimal levels of these markers.
|
1437 |
15787742
|
However, both DC populations displayed a similar capacity to take up fluorescein isothiocyanate (FITC)-albumin by macropinocytosis and FITC-Dextran by the mannose receptor and to secrete IL-12 in response to stimulation with lipopolysaccharide (LPS) or an agonistic anti-CD40 monoclonal antibody.
|
1438 |
15787742
|
Therefore, we conclude that although both DC culture methods result in the production of DC with similar functional abilities, under serum-free conditions, DC cultured in GM-CSF and IL-4 show an increased stimulatory potential over DC cultured in GM-CSF alone.
|
1439 |
15793803
|
Human monocytes were cultured with GM-CSF and IL-4 for 6 days, followed by another 2 days in the presence of piceatannol or LPS.
|
1440 |
15793803
|
The expression levels of CD1a, CD80, CD83, and CD86 as expressed by mean fluorescence intensity (MFI) on DCs differentiated from immature DCs after culture with 1 muM of piceatannol for 2 days were enhanced and decreased endocytic activity.
|
1441 |
15804174
|
Moreover, cationic liposome stimulates the expression of CD80/CD86 on dendritic cells (DCs), but not the release of TNF-alpha from DCs, suggesting the existence of a NF-kappaB-independent immunostimulation pathway for cationic lipids such as DOTAP.

|
Nonreplicating recombinant vaccinia virus expressing CD40 ligand enhances APC capacity to stimulate specific CD4+ and CD8+ T cell responses.
|
1443 |
15812230
|
Recently, we and others have demonstrated, in vitro and in vivo, that coexpression of CD80 and CD86 costimulatory molecules enhances the immunogenic capacity of a recombinant vaccinia virus (rVV) encoding different tumor-associated antigens.
|
1444 |
15812230
|
To further investigate the capacity of these vectors to provide ligands for different costimulatory pathways relevant in the generation of T cell responses, we constructed a recombinant virus (rVV) expressing CD40 ligand or CD154 (CD154rVV).
|
1445 |
15812230
|
Upon binding the CD40 receptor expressed on antigen presenting cells (APC), this molecule, physiologically expressed on activated CD4+ T cells, increases their antigen presentation and immunostimulatory capacities.
|
1446 |
15812230
|
CD154rVV infection of autologous fibroblasts, monocytes, or iDC promoted the expression of a number of cytokines, including GM-CSF, TNF-alpha, and IL-15 in iDC.
|
1447 |
15812230
|
Most importantly, IL-12 p40 gene expression and protein secretion were induced by CD154rVV but not by wild-type VV (WT VV) in either CD14+ cells or iDC, and these effects could be blocked by anti-CD40 monoclonal antibodies.
|
1448 |
15812230
|
Furthermore, phenotypic characterization of CD154rVV infected iDC revealed enhanced expression of CD83 and CD86 surface markers as compared with wild-type vaccinia virus infection.
|
1449 |
15812230
|
However, cytokine genes typically expressed by T cell receptor triggered T cells such as those encoding IL-2 and IFN-gamma, or T cell proliferation, were detectable to a significantly higher extent in CD154rVV infected cultures, as compared with WT VV.
|
1450 |
15812230
|
Activation of specific CD8+ T cells was then investigated using MART-1/Melan-A(27-35) epitope as the model of tumor-associated antigen (TAA).
|
1451 |
15814713
|
IL-10 deficiency caused early maturation and activation of pulsed DC (i.e., high CD11c, CD40, CD80, CD83, CD86, IL-1, IL-12, and the T cell-attracting chemokine CCL27/CTACK) and consequently an enhanced ability to process and present Ags for a rapid and robust T cell activation.
|
1452 |
15814713
|
Supporting comparative proteomics revealed further that IL-10 deficient DC possess specific immunobiological properties, e.g., the T cell-attracting chemokine CCL27/CTACK, calcium-dependent protein kinase, and the IL-1/IL-12 inducer, NKR-P1A (CD161), which differentiated them immunologically from wild-type DC that express molecules relating to anti-inflammatory, differentiative, and metabolic processes, e.g., the anti-IL-12 molecule peroxisome proliferator-activated receptor-alpha and thymidine kinase.
|
1453 |
15837362
|
A population of cells exhibiting bona fide dendritic cell (DC) morphological and functional characteristics was obtained by treating Aotus spp. monocytes with human IL-4 and GM-CSF.
|
1454 |
15837362
|
Although the purity of mature DCs was relatively low IL-4/GM-CSF-treated monocytes (hereafter called Aotus spp.
|
1455 |
15837362
|
DCs) down-regulated CD14 and up-regulated discrete levels of CD80, MHC-Class II and CD1b molecules in response to different maturation stimuli.
|
1456 |
15864589
|
Immunostimulatory properties of human dendritic cells generated using IFN-beta associated either with IL-3 or GM-CSF.
|
1457 |
15864589
|
In the present study, we analyze the features of type I IFNs DC generated in the presence of either IL-3 (IL-3-DC) or GM-CSF (GM-CSF-DC) and compare their capacity to respond to poly(I:C) and to subsequently trigger T-cell activation.
|
1458 |
15864589
|
After poly(I:C) maturation, both DC types display a marked upregulation of CD80, CD83 and CD86 and the same pattern of gene expression.
|
1459 |
15864589
|
Priming of autologous T cells by IL-3-DC or GM-CSF-DC pulsed with an HLA-A2 restricted melan-A derived peptide, lead to the expansion of peptide specific CTL secreting high amounts of IFN-gamma.
|
1460 |
15864589
|
We conclude that poly(I:C) matured IL-3-DC and GM-CSF-DC share similar phenotype and functional properties including the capacity to prime tumor-associated antigen specific CTL.
|
1461 |
15877606
|
Monocyte-derived dendritic cells (mDC), the most frequently applied DC subset in clinical studies, which can be obtained easily from peripheral blood monocytes after incubation with GM-CSF and IL-4, have not been clearly demonstrated to be activated by CpG oligodeoxynucleotides (ODN).
|
1462 |
15877606
|
However, we did not observe increased expression of maturation-associated and functionally relevant surface antigens (CD14, HLA-DR, CD40, CD83, CD80 and CD86), significant secretion of IL-12 and IFN-alpha in culture supernatant, or enhanced antitumour activation of cytokine-induced killer cells.
|
1463 |
15879130
|
Activated B cells exhibited increased expression of activation markers and ligands that are critical for cross-talk with T cells (CD19, CD25, CD80, CD86, MHC I, MHC II, and CD40).
|
1464 |
15891775
|
The DCs expressed CD11c, CD11b, and the costimulatory molecules CD40, CD80 and CD86, characteristic of mature DCs.
|
1465 |
15893625
|
As compared with soluble rPA, it was found that coculture of DC with rPA-loaded microparticles stimulated higher levels of MHC II, CD54, CD80 and CD86 expression (p<0.05).
|
1466 |
15936851
|
In this study, we demonstrated that WKYMVm enhanced the surface expression of CD80, but not that of CD40, CD86 and MHC class II, on mouse bone marrow-derived dendritic cells which is one of the essential costimulatory signals for the induction of immune responses.
|
1467 |
15936851
|
Furthermore, when WKYMVm was codelivered with HIV, HBV and Influenza DNA vaccines, WKYMVm selectively enhanced the vaccine-induced CD8(+) T cell responses in a dose-dependent manner, in terms of IFN-gamma secretion and cytolytic activity.
|

|
Immunization with HIV-1 Gag protein conjugated to a TLR7/8 agonist results in the generation of HIV-1 Gag-specific Th1 and CD8+ T cell responses.
|
1469 |
15944268
|
Injection of R-848 and CpG oligodeoxynucleotides alone enhanced the innate immune responses in vivo as demonstrated by high serum levels of inflammatory cytokines, including IL-12p70 and IFN-alpha, and increased expression of CD80, CD86, and CD40 on CD11c(+) dendritic cells.
|
1470 |
15944268
|
By contrast, R-848 was a relatively poor adjuvant for inducing primary Th1 or CD8(+) T cell responses when administered with HIV-1 Gag protein.
|
1471 |
15944268
|
However, when a TLR7/8 agonist structurally and functionally similar to R-848 was conjugated to HIV-1 Gag protein both Th1 and CD8(+) T cells responses were elicited as determined by intracellular cytokine and tetramer staining.
|
1472 |
15944274
|
Exposure of a LC-like cell line to ATPgammaS in the presence of LPS and GM-CSF augmented the induction of I-A, CD80, CD86, IL-1beta, and IL-12 p40 while inhibiting the expression of IL-10, suggesting that the immunostimulatory activities of purinergic agonists in the skin are mediated at least in part by P2Rs on APCs.
|
1473 |
15944302
|
Whereas RA reduced type 1 cytokines (IFN-gamma and IL-12), PIC enhanced both type 1 and type 2 cytokines (IL-4 and IL-12) and cytokine-related transcription factors.
|
1474 |
15944302
|
Despite the presence of PIC, the IL-4:IFN-gamma ratio was significantly elevated by RA.
|
1475 |
15944302
|
In addition, RA and/or PIC modulated NK/NKT cell populations and the level of expression of the costimulatory molecules CD80/CD86, evident 3 days after priming.
|
1476 |
15944302
|
Notably, the NKT:NK and CD80:CD86 ratios were correlated with the IL-4:IFN-gamma ratio, indicative of multiple converging modes of regulation.
|
1477 |
15944302
|
Whereas RA reduced type 1 cytokines (IFN-gamma and IL-12), PIC enhanced both type 1 and type 2 cytokines (IL-4 and IL-12) and cytokine-related transcription factors.

To identify DCs with differing abilities to direct Th1/Th2 cell differentiation, we cultured mouse bone marrow progenitors in granulocyte macrophage-colony stimulating factor (GM), GM + interleukin (IL)-4, or GM + IL-15 and generated three distinct DC populations.
|
1482 |
15961574
|
The GM + IL-4 DCs expressed high levels of CD80/CD86 and major histocompatibility complex (MHC) class II and produced low levels of IL-12p70.
|
1483 |
15961574
|
GM and GM + IL-15 DCs expressed low levels of CD80/CD86 and MHC class II.
|
1484 |
15961574
|
The GM + IL-15 DCs produced high levels of IL-12p70 and interferon (IFN)-gamma, whereas GM DCs produced only high levels of IL-12p70.
|
1485 |
15961574
|
Naive T cells stimulated with GM + IL-4 DCs secreted high levels of IL-4 and IL-5 in addition to IFN-gamma.
|
1486 |
15961574
|
In contrast, the GM + IL-15 DCs induced higher IFN-gamma production by T cells with little or no Th2 cytokines.

15961574
|
Naive T cells stimulated with GM + IL-4 DCs secreted high levels of IL-4 and IL-5 in addition to IFN-gamma.
|
1492 |
15961574
|
In contrast, the GM + IL-15 DCs induced higher IFN-gamma production by T cells with little or no Th2 cytokines.
|
1493 |
15972497
|
Our results showed that StxB1 and mStx1, but not native Stx1 (nStx1), resulted in enhanced expression of CD86, CD40, and major histocompatibility complex (MHC) class II molecules and, to some extent, also enhanced the expression of CD80 on bone marrow-derived DCs.
|
1494 |
15972497
|
StxB1-treated DCs exhibited an increase in tumor necrosis factor alpha and interleukin-12 (IL-12) production, a stimulation of DO11.10 T-cell proliferation, and the production of both Th1 and Th2 cytokines, including gamma interferon (IFN-gamma), IL-4, IL-5, IL-6, and IL-10.
|
1495 |
15972497
|
When mice were given StxB1 subcutaneously, the levels of CD80, CD86, and CD40, as well as MHC class II expression by splenic DCs, were enhanced.

OVA-specific CD4+ T cells isolated from mice immunized with OVA plus mStx1 or StxB1 produced IFN-gamma, IL-4, IL-5, IL-6, and IL-10, indicating that mStx1 and StxB1 elicit both Th1- and Th2-type responses.
|
1497 |
15972497
|
Our results showed that StxB1 and mStx1, but not native Stx1 (nStx1), resulted in enhanced expression of CD86, CD40, and major histocompatibility complex (MHC) class II molecules and, to some extent, also enhanced the expression of CD80 on bone marrow-derived DCs.
|
1498 |
15972497
|
StxB1-treated DCs exhibited an increase in tumor necrosis factor alpha and interleukin-12 (IL-12) production, a stimulation of DO11.10 T-cell proliferation, and the production of both Th1 and Th2 cytokines, including gamma interferon (IFN-gamma), IL-4, IL-5, IL-6, and IL-10.
|
1499 |
15972497
|
When mice were given StxB1 subcutaneously, the levels of CD80, CD86, and CD40, as well as MHC class II expression by splenic DCs, were enhanced.

In cellular activation, the CD28 ligands B7-1 (CD80) and B7-2 (CD86) are thought to play nearly identical roles in T cell activation.
|
1502 |
15981208
|
We monitored the T cell response upon co-culture with HLA Class I-matched and mismatched renal carcinoma cells, respectively, that express different levels of B7-1 and B7-2, respectively.
|
1503 |
15981208
|
In a HLA Class I-mismatched co-culture, T cell proliferation, IFN-gamma and GM-CSF secretion equally depend on the levels of B7-1 and B7-2 on tumor cells.
|
1504 |
15981208
|
In contrast, in a HLA Class I-matched situation, B7-2 is more effective in the induction of IFN-gamma and GM-CSF secretion than B7-1, but both B7 molecules induce T cell proliferation equally efficient.
|
1505 |
15981208
|
B7-2 is more effective than B7-1 in inducing TNF-alpha and IL-10 secretion in both HLA Class I-matched and mismatched situations.
|
1506 |
15981208
|
The distinct patterns of cytokine induction by B7-1 and B7-2 obviously depend on the HLA Class I compatibility.

|
Adenovirus vectors encoding carcinoembryonic antigen (Ad-CEA) or costimulatory molecules CD80, intercellular adhesion molecule-1 (ICAM-1) and leucocyte function-associated antigen-3 (LFA-3) (Ad-STIM) were used to transduce murine bone marrow-derived dendritic cells (BMDC).
|
1523 |
16179007
|
Transduction of cells grown in presence of heterologous serum increased the expression of costimulatory molecules, major histocompatibility complex class II, of IL-6 and IL-12.
|
1524 |
16179007
|
Nonetheless, CEA-specific CD8+ T-cell response was enhanced upon coinfection of Ad-STIM and Ad-CEA in both mouse strains, although this immune response was not sufficient to protect CEA-tg mice from tumour challenge.

|
1527 |
16197973
|
Cell surface expression of CD80, CD83 and CD86 on SUL-1-treated DC was inhibited by anti-DC-SIGN mAb, while anti-DC-SIGN mAb had no influence on allogeneic T cell proliferation by SUL-1-treated DC.

|
1533 |
16207252
|
Toxoplasma gondii antigen was shown to be taken up by these cells and to increase class I and class II major histocompatibility complex (MHC), CD40, CD80 and CD86 surface expression.
|
1534 |
16207252

16210624
|
Whereas CTB only delivered the Ag to MZ DC, the ADP-ribosyltransferase activity of CT was required for the maturation and migration of DC to the T cell zone, where these cells distinctly up-regulated CD86, but not CD80.
|
1536 |
16246469
|
However, both wild type meningococcal LOS and KDO(2)-lipid A, significantly up-regulated CD80, CD83 and CD86 and released significantly higher amounts of IL-12p70, IL-6, IL-10, TNFalpha, MCP-1, IP-10 and RANTES.
|
1537 |
16246469
|
Further, DCs stimulated with wild type or KDO(2)-lipid A but not meningococcal lipid A or penta-acylated KDO(2)-lipid A stimulated naïve allogeneic CD4+ T cells to secrete enhanced levels of IFN-gamma, relative to T cells primed with immature DCs.
|
1538 |
16246469
|
In contrast to Escherichia coli LPS, IL-5 production was enhanced or maintained in CD4+ T-cells stimulated with MDDC exposed to wild-type meningococcal LOS and KDO(2)-lipid A.
|
1539 |
16246469
|
These data suggest that KDO linked to a fully acylated meningococcal lipid A is required for meningococcal endotoxin's immunostimulatory activity of human MDDC via TLR4/MD-2 and that different endotoxin structures influence Th responses mediated by MDDC.

1551 |
16315029
|
To test the efficacy of vaccination with DC+B16-CD44, mice were vaccinated subcutaneously Lymphocytes from mice vaccinated with DC+B16-CD44 produced IFN-gamma in response to B16 melanoma lysates as well as an MHC class I restricted B16 melanoma-associated peptide, indicating B16 specific CD8 T cell activation.

Tumor cells transduced with the MHC class II Transactivator and CD80 activate tumor-specific CD4+ T cells whether or not they are silenced for invariant chain.
|
1559 |
16424052
|
Because expression of multiple MHC II alleles would facilitate presentation of a broader repertoire of tumor antigens, we have now transduced tumor cells with the MHC class II transactivator (CIITA), a regulatory gene that coordinately increases expression of all MHC II alleles.
|
1560 |
16424052
|
To determine if Ii expression affects presentation of MHC class II-restricted endogenously synthesized tumor antigens in human tumor cells, HLA-DR-MCF10 breast cancer cells were transduced with the CIITA, CD80 costimulatory molecule gene, and with or without small interfering RNAs (siRNA) specific for Ii.
|
1561 |
16424052
|
Ii expression is silenced >95% in CIITA/CD80/siRNA transductants; down-regulation of Ii does not affect HLA-DR expression or stability; and Ii(+) and Ii(-) transductants activate human CD4+ T cells to DRB1*0701-restricted HER-2/neu epitopes.
|
1562 |

C274 induced macaque CD20(+) B cells to proliferate more strongly than CD40 ligand or CpG-B ISS-ODN.
|
1579 |
16443827
|
Increased expression of CD40, CD80, and CD86 by B cells was apparent within 24 h of exposure to C274 and persisted for up to 1 week.
|
1580 |
16443827
|
C274-stimulated, B cell-enriched and peripheral blood mononuclear cell suspensions from naïve and immunodeficiency virus-infected monkeys secreted several cytokines [e.g., interleukin (IL)-3, IL-6, IL-12, interferon-alpha] and chemokines [e.g., monocyte chemoattractant protein-1/CC chemokine ligand 2 (CCL2), macrophage-inflammatory protein-1alpha/CCL3, IL-8/CXC chemokine ligand 8].

Culturing in the presence of granulocyte monocyte colony stimulating factor (GM-CSF) increased the in vitro differentiation and maturation of these cells into BM-derived DCs (CD11c+ and MHC class II+).
|
1582 |
16446175
|
Maturation of DCs was determined by increased CD80 and CD86 expression, IL-4 and IL-12 production, reduction in phagocytic capacity and increase in the antigen presenting ability to primed or naïve T lymphocytes.

In this study, we show that BLS stimulates bone marrow dendritic cells from mice in vitro to up-regulate the levels of costimulatory molecules (CD40, CD80, and CD86) and major histocompatibility class II Ag.
|
1585 |
16474127
|
Our results demonstrate that, in contrast to the rwt virus, rM51R-M virus induced the maturation of myeloid DC (mDC) populations, as indicated by an increase in the surface expression of CD40, CD80, and CD86 as well as the secretion of interleukin-12 (IL-12), IL-6, and type I IFN.
|
1586 |
16474127
|
Our studies also indicated that the production of costimulatory molecules on mDC by rM51R-M virus was dependent on the type I IFN receptor, while maturation induced by this virus was largely independent of MyD88.

Myeloid cells had a CD4+CD11b+CD11c+CD16+CD123(low)HLA-DR- phenotype, expressed myeloperoxidase, and included a population of M-CSFR+ monocyte-lineage committed cells.
|
1588 |
16493050
|
Further culture of myeloid cells in serum-free medium with GM-CSF and IL-4 generated cells that had typical dendritic morphology; expressed high levels of MHC class I and II molecules, CD1a, CD11c, CD80, CD86, DC-SIGN, and CD40; and were capable of Ag processing, triggering naive T cells in MLR, and presenting Ags to specific T cell clones through the MHC class I pathway.

These cells can be generated from peripheral blood monocytes cultured with granulocyte macrophage-colony stimulating factor (GM-CSF) and interleukin-4 (IL-4).
|
1593 |
16499575
|
We found that 24-h IFN-alpha co-culture of day 7 monocyte-derived DC generated with GM-CSF and IL-4 induces increased numbers of DC positive for CD54 and CD40 together with the co-stimulatory molecule CD80 but not the activation marker CD83.
|
1594 |
16499575
|
Also, IFN-alpha maturation leads to an increase in IP-10 and MCP-1 chemokine secretion, but only a minor increase in IL-12p40 secretion.

Dendritic cells express CCR7 and migrate in response to CCL19 (MIP-3beta) after exposure to Helicobacter pylori.
|
1596 |
16500130
|
Migration of DC to lymph nodes is regulated by chemokine receptor CCR7, expressed on mature DC, and the CCR7 ligands CCL19 and CCL21.
|
1597 |
16500130
|
Stimulation with H. pylori induced maturation of DC, i.e. up-regulation of the chemokine receptors CCR7 and CXCR4 and the maturation markers HLA-DR, CD80 and CD86.
|
1598 |
16500130
|
Despite low surface expression of CCR7 protein following stimulation with H. pylori compared to E. coli, the DC migrated equally well towards CCL19 after stimulation with both bacteria.
|
1599 |
16621031
|
Various adhesion molecules, such as B7-1 (CD80) and heat stable antigen (HSA, CD24), expressed on antigen presenting cells have been demonstrated to provide costimulatory signals to T cells.

16621190
|
The VLP induced an increase in expression of CD40, CD80 and CD86 but required an adjuvant, CpG DNA oligo-deoxy nucleotides (ODN) motifs, to enhance these responses.
|
1601 |
16630025
|
Interferon-alpha (IFN-alpha) alone was a poor inducer of MoDC maturation, but in association with tumour necrosis factor-alpha (TNF-alpha), or TLR ligands such as lipopolysaccharide and polyinosinic-polycytidylic acid I:C, an up-regulation of major histocompatibility complex II and CD80/86 expression was noted, along with reduced endocytic activity.
|
1602 |
16630025
|
Indeed, MoDC did not respond to transmissible gastroenteritis virus (TGEV), whereas NIPC produced high levels of IFN-alpha and TNF-alpha after TGEV stimulation.

We hypothesized that plasmacytoid dendritic cells, the cells that provide large amounts of IFN-alpha in response to Toll-like receptor 9 (TLR9) agonists, are defective in neonates.
|
1606 |
16690948
|
TLR9-stimulation of whole blood from adults and neonates resulted in comparable amounts of IFN-alpha production.
|
1607 |
16690948
|
However, we observed small but significant differences in IFN-alpha production from purified CD123+ plasmacytoid dendritic cells from neonates after stimulation with the TLR9 ligand CpG-DNA.
|
1608 |
16690948
|
While purified CD123+ plasmacytoid dendritic cells from adults up-regulated co-stimulatory molecules CD80 and CD86 with IL-3 alone those from neonates required the addition of CpG-DNA to reach adult levels.

16741971
|
Interestingly, BORIS induces demethylation and subsequent expression of many cancer-testis genes, including MAGE-A1 and NY-ESO-1, indicating that it is expressed very early in malignancy and might be an attractive candidate for immunotherapy.

Besides TLRs, mRNA for MyD88 and TRAF6, and nuclear translocation of NF-kappaB were enhanced that indicate their involvement in tandem in the activity of porin.
|
1613 |
16750567
|
The protein selectively up-regulated CD80 on the activated MPhi together with MHC class II molecule and CD40, and had no effect on CD86 expression.

|
The porin-induced profile of MIP-1alpha, MIP-1beta and RANTES showed strong bias for chemokines correlated with M1 polarization.
|
1615 |
16750567
|
Intracellular expression and release of TNF-alpha and IL-12 in presence of porin was found to be TLR2 and NF-kappaB dependent.
|
1616 |
16750567
|
Induction of TNF-alpha and IL-12 along with the chemokine profile suggests type I polarization of the MPhi that would influence Th1-type response.
|
1617 |

PL-OVA presented OVA-specific peptides to CD4+ and CD8+ OVA-specific T-cell hybridomas.
|
1622 |
16823912
|
PL exerts an immunomodulatory effect on DC and is a general system to deliver antigens for presentation to CD4+ and CD8+ T-cells possibly implicated in the induction CD8+ cytotoxic T lymphocytes (CTLs) responses.

Our results showed that LMP2 gene transfer did not alter the typical morphology of mature DC, and the representative phenotypes of mature DC (CD80, CD83, and CD86) were highly expressed in rAd-LMP2-DCs.
|
1636 |
16842756
|
In addition, phenotypic analysis demonstrated that the LMP2-specific CTLs consisted of both CD4(+) and CD8(+) T cells.

|
This activation induces the production of tumor necrosis factor alpha (TNF-alpha), an up-regulation of the surface molecules CD83, CD80, CD86, HLA-DR and HLA-I and increases the T cell stimulatory capacity of DCs.
|
1638 |
16917781
|
BMDCs activated with PLPs up-regulated CD40, CD80, CD86 and major histocompatibility complex (MHC) class II surface markers and produced proinflammatory cytokines.
|
1639 |
16917781
|
Chimeric PLPs [expressing the ovalbumin (OVA)-peptides OVA(257-264) or OVA(323-339)], but not wildtype PLPs, activated OVA-specific CD8 T cells and OVA-specific CD4 T cells, respectively, indicating both MHC class I and II presentation of the peptides by antigen-presenting cells.

16960116
|
Treatment of human monocytes with S. gordonii but not latex beads induced a clear up-regulation of CD83, CD40, CD80, and CD54 and the down-regulation of CD14.
|
1641 |
16960116
|
Furthermore, bacterial treatment stimulated an increased expression of Toll-like receptor 5 (TLR5), TLR6, and TLR7, production of the proinflammatory cytokines tumor necrosis factor alpha and interleukin 1 beta, and reduction of the phagocytic activity.
|
1642 |
16971487
|
Here, we describe an approach to enhance immunogenicity that involves the activation of NF-kappaB by the transgenic expression of an intracellular signaling molecule, NF-kappaB-inducing kinase (NIK).
|
1643 |
16971487
|
In vitro, NIK increases dendritic cell antigen presentation in allogeneic and antigen-specific T cell proliferation assays by potently activating NF-kappaB and consequently up-regulating the expression of cytokines (TNF-alpha, IL-6, IL-12, IL-15, and IL-18), chemokines [IL-8, RANTES (regulated on activation, normal T cell expressed and secreted), macrophage inflammatory protein-1alpha, monocyte chemoattractant protein-1, and monocyte chemoattractant protein-3], MHC antigen-presenting molecules (class I and II), and costimulatory molecules (CD80 and CD86).
|
1644 |
16971487
|
In vivo, NIK enhances immune responses against a vector-encoded antigen and shifts them toward a T helper 1 immune response with increased IgG2a levels, T cell proliferation, IFN-gamma production, and cytotoxic T lymphocyte responses more potently than complete Freund's adjuvant, a very efficacious T helper 1-inducing adjuvant.
|
1645 |
16971487
|
These findings define NIK, and possibly other inducers of NF-kappaB activation, as a potent adjuvant strategy that offers great potential for genetic vaccine development.

In this study, we showed that ovalbumin (OVA) protein-pulsed DC (DC(OVA))-derived EXO (EXO(OVA)) displayed MHC class I-OVA I peptide (pMHC I) complexes, CD11c, CD40, CD80, CCR7, DEC205, Toll-like receptor 4 (TLR4), TLR9, MyD88 and DC-SIGN molecules, but at a lower level than DC(OVA).
|
1683 |
17073943

Here, the presence of the ingested MP did not affect the MoDC maturation in terms of expression of the surface markers CD80, CD83, CD86, HLA-DR and MMR, irrespective of the MP surface coating.
|
1689 |
17118442
|
MP-loaded and subsequently matured MoDC expressed high levels of the chemokine receptor CCR7, whose functional activity was evidenced by the migration of MoDC towards CCL21, irrespective of the presence of ingested MP.
|
1690 |
17118497
|
Specifically, the co-culture with activated Vgamma9Vdelta2 T cells with BCG-infected DC resulted in a significant increase of the expression of CD80, CD86, CD40 and CD25 molecules on DC.
|
1691 |
17118497
|
Moreover, DC were able to produce increased levels of TNF-alpha and synthesize ex novo IL-15 without altering the IL-10/IL-12 immunoregulatory pathway.
|
1692 |
17118982
|
Only LT-IIa and LT-IIa(T14S), however, enhanced expression of major histocompatibility complex class II and the costimulatory molecules CD40, CD80, and CD86 on splenic dendritic cells.

We have shown that the CpG-C ISS-ODN C274 stimulates macaque blood dendritic cells (DCs) and B cells and augments SIV-specific IFN-gamma responses in vitro.
|
1694 |
17142751
|
This was particularly apparent at the level of CD80 (less so CD86) expression by CD123(+) plasmacytoid DCs and was further boosted in the presence of additional C274 in vitro.
|
1695 |
17142751
|
This was more pronounced when cells were exposed to additional stimuli in vitro, producing IFN-alpha, IL-3, IL-6, IL-12, TNF-alpha, CCL2, CCL3, CCL5, and CXCL8.
|
1696 |
17142751
|
Elevated IFN-alpha, CCL2, and CCL5 were also detected in the plasma after C274 injection.

DC pulsed with P. carinii did not demonstrate increased expression of the cell surface markers MHC II, CD40, CD54, CD80 (B7.1), and CD86 (B7.2).
|
1698 |
17198083
|
The release of interleukin (IL)-4 was increased, but there was no increase in the release of interleukin (IL)-12p40, IL-10, tumor necrosis factor-alpha, IL-6, and nitrite compared with naive DC.
|
1699 |
17198083
|
In vivo administration of DC pulsed with P. carinii induced a P. carinii-specific response, generating CD4+ cells that proliferated and released IL-4, but not interferon-gamma, in response to P. carinii-pulsed DC in vitro.

1703 |
17255244
|
In CYD-infected DCs, we observed an up-regulation of HLA-DR, CD80, CD86, and CD83.
|
1704 |
17255244
|
Cells exposed to CYD secreted type I interferons, monocyte chemoattractant protein 1 (MCP-1)/CC chemokine ligand 2 (CCL-2), interleukin-6 (IL-6), and low amounts of tumor necrosis factor-alpha (TNF-alpha), but no IL-10, IL-12, or IL-1alpha.
|
1705 |
17255244
|
Parental dengue viruses induced a similar array of cytokines, but more TNF-alpha, less IL-6, and less MCP-1/CCL-2 than induced by CYD.

DC were propagated from C3H (H2(k)) bone marrow (BM) using granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin-4 (IL-4).
|
1707 |
17275522
|
Expression of major histocompatibility complex (MHC) class I and II was not affected, while CD40, CD80, and CD86 costimulatory molecules on DC were significantly inhibited by treatment with TGF-beta.
|
1708 |
17275522
|
This observation correlated with reduced interferon-gamma (IFN-gamma) and increased IL-10 production.
|
1709 |
17277122
|
Human immature dendritic cells (DCs) cultured in the presence of c-di-GMP showed increased expression of costimulatory molecules CD80/CD86 and maturation marker CD83, increased MHC class II and cytokines and chemokines such as IL-12, IFN-gamma, IL-8, MCP-1, IFN-gamma-inducible protein 10, and RANTES, and altered expression of chemokine receptors including CCR1, CCR7, and CXCR4. c-di-GMP-matured DCs demonstrated enhanced T cell stimulatory activity. c-di-GMP activated p38 MAPK in human DCs and ERK phosphorylation in human macrophages. c-di-GMP is stable in human serum.

|
1712 |
17285277

|
The hybrid cells stimulated allogeneic and autologous T-cell proliferative responses in vitro to a considerably greater degree than their respective parent myeloma plasma cells, and directly activated both CD4+ and CD8+ T-cell responses.
|
1715 |
17302859
|
The enhanced T-cell stimulation correlated with expression of CD80 on the hybrid cells, and was inhibited by CTLA4-Ig fusion protein.

|
Supplementation with both anti-CD40 and OK432 resulted in induction of activated DCs with higher surface expression of CD80, CD83, CD86 and major histocompatibility complex class II antigens, compared with other mature DCs that were induced by the combination of anti-CD40 with tumor necrosis factor-alpha or lipopolysaccharide.
|
1717 |
17371857
|
Markedly different effects on the immune system were observed; an IS901-negative strain (WAg 207) induced significant up-regulation of cell surface activation markers (major histocompatibility complex II, CD80, and CD86) on in vitro-derived dendritic cells and induced the release of proinflammatory monokines (interleukin-1beta [IL-1beta], IL-6, and tumor necrosis factor alpha) in dendritic cell-macrophage cocultures following direct in vitro contact of cells with bacteria.

|
Maturation markers (CD80, CD86, MHC Class II molecules) showed significantly enhanced expression on DC pulsed with high density R8-modified liposomes containing mycobacterial CW.
|
1722 |
17467840
|
Moreover, R8-modified liposomes with mycobacterial CW incorporated induced production of IL-12 p40 by DC, at levels similar to those produced by lipopolysaccharide-pulsed DC.

Tumor lysate-pulsed DCs were rendered TGF-beta insensitive by dominant-negative TGF-beta type II receptor (TbetaRIIDN), leading to the blockade of TGF-beta signals to members of the Smad family, which are the principal cytoplasmic intermediates involved in the transduction of signals from TGF-beta receptors to the nucleus.
|
1724 |
17473921
|
Phosphorylated Smad-2 was undetectable and expression of surface co-stimulatory molecules (CD80/CD86) were upregulated in TbetaRIIDN DCs after antigen and TGF-beta1 stimulation.
|
1725 |
17473921
|
Vaccination of C57BL/6 tumor-bearing mice with the TbetaRIIDN DC vaccine induced potent tumor-specific cytotoxic T lymphocyte responses against TRAMP-C2 tumors, increased serum IFN-gamma and IL-12 level, inhibited tumor growth and increased mouse survival.

|
In addition, the study demonstrates that PIKA promotes the maturation of bone marrow-derived dendritic cells (BMDCs) including up-regulation of the co-stimulatory molecules CD80, CD86 and CD40, and the induction of cytokines such as IL-12p70, IL-12p40 and IL-6.

Both aluminum-containing adjuvants significantly increased the expression of CD86 on DCs but only aluminum hydroxide adjuvant also induced moderate expression of CD80.
|
1728 |
17485153
|
Aluminum-containing adjuvants stimulated the release of IL-1beta and IL-18 from DCs via caspase-1 activation.
|
1729 |
17485153
|
In contrast, DCs incubated with aluminum/OVA activated CD4(+) T cells to secrete IL-4 and IL-5 as well as IFN-gamma.
|
1730 |
17485153
|
Addition of neutralizing anti-IL-1beta antibodies decreased IL-5 production and addition of anti-IL-18 antibodies decreased both IL-4 and IL-5 production.
|
1731 |
17485153
|
Inhibition of IL-1beta and IL-18 secretion by DCs via inhibition of caspase-1 also led to a marked decrease of IL-4 and IL-5 by CD4(+) T cells.
|
1732 |
17485153
|
These results indicate that aluminum-containing adjuvants activate DCs and influence their ability to direct T(H)1 and T(H)2 responses through the secretion of IL-1beta and IL-18.

Human peripheral blood CD14(+) monocytes were purified by using a magnetic separation column and cultured with GM-CSF and IL-4 to differentiate into immature DCs (iDCs).
|
1759 |
17532057
|
In the presence of Talpha1, iDC surface markers CD40, CD80, MHC class I and class II molecules were significantly upregulated as measured by flow cytemotry analysis.
|
1760 |
17532057
|
Thus, Talpha1 significantly enhances DC differentiation, activation, and functions from human peripheral blood CD14(+) monocytes possibly through a mechanism of the activation of p38 MAPK and NFkappaB pathways.

Co-immunisation with DNA encoding RANK/RANKL or 4-1BBL costimulatory molecules does not enhance effector or memory CTL responses afforded by immunisation with a tumour antigen-encoding DNA vaccine.
|
1762 |
17544551
|
This 'second signalling' occurs through the B7 molecules CD80/86 expressed by DCs, and importantly through members of the TNF ligand/TNF receptor superfamilies.
|
1763 |
17544551
|
We have previously shown that co-expression of RANK/RANKL or 41BB-L in addition to tumour antigen in dendritic cells augmented cognate effector and memory tumour antigen-directed cytotoxic T cell responses when the DCs were used to immunise mice.

1767 |
17626150
|
The EXO(OVA)-uptaken CD4(+) aT(EXO) cell vaccine induces much more efficient CD8(+) T cell responses and immunity against challenge of OVA-transfected BL6-10 melanoma cells expressing OVA in wild-type C57BL/6 mice than EXO(OVA).
|
1768 |
17626150

The purpose of the present study was to determine the functional role of CD80 and CD86 in mediating systemic and mucosal immune responses to the recombinant HArep derived from the gingipain Kgp (Kgp-HArep) after intranasal (i.n.) immunization.
|
1777 |
17629367

The in vivo functional roles of CD80 and CD86 were assessed in C57BL/6 wild-type (wt), CD80(-/-), CD86(-/-) and CD80/CD86(-/-) mice following intranasal immunization with Kgp-HArep with or without adjuvant.
|
1778 |
17629367
|
Compared to wt and CD80(-/-) mice, CD86(-/-) mice had reduced serum IgG anti-Kgp-HArep responses following the second immunization with antigen alone or antigen+CTB, whereas similar levels of serum IgG anti-Kgp-HArep antibody activity were observed in wt, CD80(-/-) and CD86(-/-) mice immunized with antigen+MPL.
|
1779 |
17629367
|
Analysis of the serum IgG subclass responses revealed that CD80 influenced both Th1- and Th2-like IgG subclass responses, while CD86 preferentially influenced a Th2-associated IgG subclass response to Kgp-HArep.

1780 |
17629367

Compared to wt and CD80(-/-) mice, CD86(-/-) mice had reduced serum IgG anti-Kgp-HArep responses following the second immunization with antigen alone or antigen+CTB, whereas similar levels of serum IgG anti-Kgp-HArep antibody activity were observed in wt, CD80(-/-) and CD86(-/-) mice immunized with antigen+MPL.
|
1821 |
17629367
|
Analysis of the serum IgG subclass responses revealed that CD80 influenced both Th1- and Th2-like IgG subclass responses, while CD86 preferentially influenced a Th2-associated IgG subclass response to Kgp-HArep.

|
1823 |
17629367
|
Taken together, our results demonstrate that CD80 and CD86 can play distinct as well as redundant roles in mediating a systemic immune response and that CD86 plays a unique role in mediating a mucosal response to Kgp-HArep following immunization via the i.n. route alone or with adjuvant.

|
These EXO(OVA)-uptaken (targeted) CD4+ aT cells can stimulate CD8+ T cell proliferation and differentiation into central memory CD8+ CTLs and induce more efficient in vivo antitumor immunity and long-term CD8+ T cell memory responses than OVA-pulsed dendritic cells.

They can also counteract CD4+25+ regulatory T cell-mediated suppression of in vitro CD8+ T cell proliferation and in vivo CD8+ CTL responses and antitumor immunity.
|
1828 |
17709486
|
We further elucidate that the EXO(OVA)-uptaken (targeted)CD4+ aT cell's stimulatory effect is mediated via its IL-2 secretion and acquired exosomal CD80 costimulation and is specifically delivered to CD8+ T cells in vivo via acquired exosomal peptide/MHC class I complexes.

|
1832 |
17765973
|
Moreover, even if KLH stimulated the production of IL-12 and IL-10 by DCs, the final balance was clearly in favour of IL-12.

After priming with IFN-gamma and stimulation with NadADelta351-405, mo-DCs strongly up-regulated maturation markers CD83, CD86, CD80, and HLA-DR, secreted moderate quantities of TNF-alpha, IL-6, and IL-8, and produced a slight, although significant, amount of IL-12p70.
|
1834 |
17785828
|
Costimulation of mo-DCs with NadADelta351-405 and the imidoazoquinoline drug R-848, believed to mimic bacterial RNA, increased CD86 in an additive way, but strongly synergized the secretion of IL-12p70, IL-1, IL-6, TNF-alpha, and MIP-1alpha, especially after IFN-gamma priming.

The infection of mDCs induced apoptosis, reduced the expression of CD80/86 and major histocompatibility complex class II molecules, and increased the expression of interleukin-10, thus suggesting that such mDC modulation results in the impairment of T-cell activation.

We examined this vaccine's biologic characteristics and immune activity in vitro, finding that infection with the polyepitope adenovirus did not alter the typical morphology of mature DC and the typical markers of these cells (CD86, CD83, CD80, and HLA-DR) were highly expressed on rAd-pE-DCs.

We found that after the first recall stimulation with MAP4, the major cell population was predominantly CD4(+) T-cell subsets (68.5%), CD8(+high) (16%) and CD19(+) (10%).
|
1913 |
18565118

Additionally, MAP4 PIV cells significantly expressed CD4(+)-HLA-DR(+), -CD54(+), -CD45RO(+) (P < 0.0001) and -CD25(+) (P < 0.0004) together with significant expression of CD80(+) on CD19(+) B cells (P < 0.007).

Costimulatory molecules B7.1 (CD80) and B7.2 (CD86) have improved the efficacy of gene-based and cell-based vaccines in animal models and are under investigation in clinical trials.
|
1916 |
18600180
|
However, their efficacy as vaccine adjuvants is likely limited by the fact that they mediate both stimulatory and inhibitory signals to T cells via CD28 and CTLA-4, respectively.
|
1917 |
18600180
|
To overcome these limitations, we have generated a B7.1-like, chimeric costimulatory molecule with preferential binding to CD28, named CD28-binding protein (CD28BP), which we combined with a modified, nonself tumor antigen variant of epithelial cell adhesion molecule (EpCAM), named TAg25.
|
1918 |

In contrast, TAg25 combined with CD28BP induced both CD4 and CD8 T cells specific for EpCAM.

Abstract The development of tumor vaccines or generation of tumor-specific cytotoxic T lymphocytes (CTL) is limited by the fact that many tumor cells downregulate the expression of major histocompatibility complex (MHC) Class I and II molecules, as well as key co-stimulatory molecules such as CD80 and CD86.

|
1930 |

Here, the response of monocytes to CD40 ligand (CD40L) for patients with sepsis due to infection with gram-negative organisms has been analyzed.
|
1933 |
18945879
|
Compared to cells from controls, monocytes from septic patients showed significantly reduced production of tumor necrosis factor alpha, interleukin-1beta (IL-1beta), and IL-12 and were unable to acquire high levels of CD80 and CD86 molecules.
|
1934 |
18945879
|
In addition, costimulation of autologous CD4+ T lymphocytes by CD40L-activated monocytes from septic patients failed to induce cell proliferation and gamma interferon production.

|
The CD8 T cells expressed augmented levels of perforin, IFN-gamma and TNF-alpha and mediated CTCL cell apoptosis.
|
1937 |
18996429
|
Immunization with antigen (sAg) encapsulated in saccharosome resulted in enhancement of CD4+ and CD8+ T cell populations and also up-regulated the expression of CD80 and CD86 molecules on the surface of antigen presenting cells.
|
1938 |
18996429
|
Further, immunization with saccharosome-encapsulated sAg-induced elevated levels of both IFN-gamma and IL-4 cytokines in the immunized mice when compared to egg PC liposome encapsulated sAg or its IFA emulsified form.

During T cell interaction with APC, CD28 is recruited to the central region (cSMAC) of the immunological synapse.
|
1940 |
19017952
|
CD28-mediated signaling through PI3K results in the recruitment of protein kinase C-theta (PKCtheta) to the cSMAC, activation of NF-kappaB, and up-regulation of IL-2 transcription.
|
1941 |
19017952
|
In this report, we show that CD28 recruitment and persistence at the immunological synapse requires TCR signals and CD80 engagement.
|
1942 |
19017952
|
Addition of mAb to either MHC class II or CD80 results in the rapid displacement of CD28 from the immunological synapse.
|
1943 |
19017952
|
Ligand binding is not sufficient for CD28 localization to the immunological synapse, as truncation of the cytosolic tail of CD28 disrupts synapse localization without effecting the ability of CD28 to bind CD80.
|
1944 |
19017952
|
Mutation of tyrosine 188 also results in diminished activation of NF-kappaB, suggesting that CD28-mediated localization of PKCtheta to the cSMAC is important for efficient signal transduction.

|
To improve vaccine immunogenicity, we incorporated CD40 ligand (CD40L) into the dSIV envelope.
|
1960 |
19036823
|
Binding of CD40L to its receptor upregulates expression of major histocompatibility complex class I, class II, and costimulatory molecules on DCs and increases production of proinflammatory cytokines and chemokines, especially interleukin 12 (IL-12).
|
1961 |
19036823
|
Expression levels of CD80, CD86, HLA-DR, and CD54 on DCs transduced with the dSIV incorporating CD40L (CD40L-dSIV) were significantly higher than on those transduced with dSIV.
|
1962 |
19036823
|
Moreover, CD40L-dSIV-transduced DCs expressed up to 10-fold more IL-12 than dSIV-transduced DCs.

The 60 kDa heat shock protein (HSP60) has been reported to influence T-cell responses in two ways: as a ligand of toll-like receptor 2 signalling and as an antigen.
|
1964 |
19107191
|
Presentation of HSP60 by activated T cells was found to be MHC-restricted and dependent on accessory molecules - CD28, CD80 and CD86.
|
1965 |
19107191
|
Anti-ergotypic T cells responded to T-cell HSP60 by proliferation and secreted IFNgamma and TGFbeta1.
|
1966 |
19107191
|
In vivo, adoptive transfer of an anti-ergotypic HSP60-specific T-cell line led to decreased secretion of IFNgamma by arthritogenic T cells and ameliorated adjuvant arthritis (AA).

Typhi(F1) enhanced the activation and maturation of neonatal CD11c+ dendritic cells, shown by increased expression of CD80, CD86, CD40, and MHC-II cell surface markers and production of proinflammatory cytokines IL-12, TNF-alpha, IL-6, and MCP-1.
|
1969 |
19124765
|
Typhi(F1)-stimulated neonatal DC had improved capacity for Ag presentation and T cell stimulation in vitro and induced F1-specific CD4+ and CD8+ T cell responses when adoptively transferred to newborn mice.
|
1970 |
19141400
|
After 7 days of culture, DCs were harvested and the expression of CD1a, CD83, CD80, CD86 and HLA-DR antigens were analyzed by flow cytometry.
|
1971 |
19141400
|
The expression of co-stimulatory and maturation markers (CD86, CD83 and HLA-DR) was higher on DCs from the culture with tumor cell lysate compared with TNF-alpha culture as a control.
|
1972 |
19237530
|
Efficient uptake of the polymeric peptide in vitro resulted in higher expression of the coactivation markers CD80, CD40, and CD70 on dendritic cells and higher proinflammatory cytokine production than with the monomeric peptide.
|
1973 |
19278729
|
Peptidoglycan (PGN), lipoteichoic acid (LTA), lipoprotein (LP), and DNA were also isolated from the bacteria, and used to stimulate BM-DCs.
|
1974 |
19278729
|
Stimulation with TNF, S. gordonii, PGN, LTA, or LP all resulted in increased surface expression of MHCII, CD80, and CD86, compared to unstimulated BM-DCs.
|
1975 |
19278729
|
Stimulation with S. gordonii elicited IL-6, IL-10, and IL-12p70 production from the BM-DCs, while stimulation with the bacterial components induced some or all of the three cytokines.
|
1976 |
19278729
|
When BM-DCs were simultaneously stimulated with S. gordonii and TNF, a marginal increase in surface marker upregulation was observed, and the two stimuli synergized to elicit substantially greater quantities of IL-6, IL-10, and IL-12p70.
|
1977 |
19278729
|
The effect of TNF was abolished when BM-DCs were obtained from mice deficient for either TNFR1 or TNFR2, and cytokine induction by S. gordonii was entirely dependent on functional MyD88.
|
1978 |
19278729
|
Synergistic IL-10 induction by S. gordonii and TNF was not observed in TLR-2(-/-) BM-DCs, and TNF was found to cause TLR-2 upregulation, providing at least a partial mechanism for the observed synergy.
|

Immature dendritic cells (iDCs) are often produced by the stimulation of peripheral blood monocytes with interleukin (IL)-4 and granulocyte macrophage-colony stimulating factor.
|
1980 |
19342965
|
The purpose of this study was to determine if the DC maturation cocktail LPS plus IFN-gamma could be improved by the addition of 2 other DC maturation agents IL-1beta and tumor necrosis factor (TNF)-alpha.
|
1981 |
19342965
|
Monocytes were isolated from the peripheral blood mononuclear cell concentrates by elutriation and were incubated for 3 days with granulocyte macrophage-colony stimulating factor and IL-4 to produce iDCs. iDCs from each subject were divided into 3 and were incubated for 24 hours with LPS plus IFN-gamma; LPS, IFN-gamma, plus IL-1beta; or LPS, IFN-gamma, IL-1beta, plus TNF-alpha to produce mDCs.
|
1982 |
19342965
|
The DCs were compared by measuring the expression of costimulator and antigen presenting molecules (CD80, CD83, CD86, and human leukocyte antigen-DR) by flow cytometry, cytokine production (IL-12p70 and IL-10) by enzyme-linked immunosorbent assay and global gene expression using an oligonucleotide microarray.
|
1983 |
19342965
|
There was no benefit of adding IL-1beta and TNF-alpha to LPS and IFN-gamma to produce mDCs.

19494083
|
Adherent peritoneal cells from rats treated with PSC-CFA, however, also presented upregulated ED2, CD80, and CD86 expression compared to the level of expression for peritoneal cells from controls, but these cells showed an increase in arginase activity and decreased levels of production of IL-12 and tumor necrosis factor (TNF) compared with the activity and levels of production by peritoneal cells from CFA-PBS-treated rats.

Sheep were primed by particle-mediated epidermal bombardment with VMV gag and env gene recombinant plasmids together with plasmids encoding both CD80 and CD86 or CD80 alone, boosted with gag and env gene recombinant modified vaccinia Ankara virus and challenged intratracheally with VMV.
|
1993 |
19538997
|
Immunization in the presence of one or both of the B7 genes resulted in CD4+ T cell activation and antibody production (before and after challenge, respectively), but only immunization with CD80 and CD86 genes together, and not CD80 alone, resulted in a reduced number of infected animals and increased early transient cytotoxic T lymphocytes (CTL) responses.

T-cell activation requires both antigen presentation to the T-cell receptor and a second signal mediated by CD80 and CD86 on antigen-presenting cells and CD28 on the T cell.
|
1997 |
19556898
|
Ligand binding to CD28 on the T-cell surface leads to T-cell proliferation and expression of activating cytokines such as interleukin-2.
|
1998 |
19556898
|
Cytotoxic T-lymphocyte antigen-4 (CTLA-4), an inhibitory protein expressed on T cells, competes for the same ligands as CD28 and modulates T-cell activation.
|
1999 |
19556898
|
Because CTLA-4 has a significantly higher binding efficiency than CD28, CTLA-4 is critical in maintaining immune tolerance to self-antigens and may also limit responses to tumor antigens and vaccine therapy.

Uveal melanoma cell-based vaccines express MHC II molecules that traffic via the endocytic and secretory pathways and activate CD8+ cytotoxic, tumor-specific T cells.
|
2001 |
19557412
|
MHC II uveal melanoma vaccines are MHC class I(+) uveal melanoma cells transduced with CD80 genes and MHC II genes syngeneic to the recipient.
|
2002 |
19557412
|
We also demonstrate that uveal melanoma MHC II vaccines activate uveal melanoma-specific, cytolytic CD8(+) T cells that do not lyse normal fibroblasts or other tumor cells.
|
2003 |
19557412
|
Surprisingly, the CD8(+) T cells are cytolytic for HLA-A syngeneic and MHC I-mismatched uveal melanomas.
|
2004 |
19557412
|
Collectively, these studies demonstrate that MHC II uveal melanoma vaccines are potent activators of tumor-specific CD4(+) and CD8(+) T cells and suggest that the non-conventional intracellular trafficking pattern of MHC II may contribute to their enhanced immunogenicity.
|
2005 |
19557412
|
Since MHC I compatibility is unnecessary for the activation of cytolytic CD8(+) T cells, the vaccines could be used in uveal melanoma patients without regard to MHC I genotype.

2008 |
19578511
|
Naïve T cells co-cultured with allogeneic M1-primed DC, M4-primed DC, T-cadinol-primed DC or calamenene-primed DC turned into typical Th1 cells, which produced large quantities of IFN-gamma and released small amounts of IL-4 depending on IL-12 secretion.
|
2009 |
19578511
|
In the CTL assay (cytotoxic T-lymphocyte assay), the production of IFN-gamma and (51)Cr release on M4-primed DC was more augmented than of immature DC or TNF-alpha-primed DC.

WSL enhanced Th1 cytokine IFN-gamma expression in Con A primed splenocytes in vitro.
|
2014 |
19628058
|
When given orally for 2 weeks to BALB/c mice immunized with emulsion of OVA in Freund's adjuvant (OVA-FCA), it caused dose-dependent proliferation of T cells and improved their ability to secrete IL-2 and IFN-gamma, but moderately down-regulated Th2 cytokine IL-4.
|
2015 |
19628058
|
Flow cytometric analysis of lymphocyte surface markers of T cells CD3(+), CD4(+) and CD8(+), and B cells CD19(+) indicated prominent enhancement in proliferation and differentiation of lymphocytes.

Further, the effect of WSL in immunized mice elicited up-regulation of beta-integrins LFA (CD11a) and Mac-1 (CD11b) in splenocytes.
|
2017 |
19628058
|
Co-stimulatory molecules CD80 and CD86 that are important secondary signals for the activation of immune system elicited remarkable enhanced expression when observed in spleen-derived macrophages isolated from WSL treated mice.

|
2046 |
19711075
|
We have previously shown that in vitro stimulation of autologous peripheral blood mononuclear cells (PBMCs) with primary AML cells modified to express CD80 and IL-2 promotes proliferation, secretion of Th1 cytokines and expansion of activated CD8(+) T cells.
|
2047 |
19711075
|
In this study, we show that allogeneic effector cells (from a healthy donor or AML patients) when stimulated with IL-2/CD80 modified AML blasts were able to induce the lysis of unmodified AML blasts.
|
2048 |
19711075
|
Effector cells stimulated with IL-2/CD80AML blasts had higher lytic activity than cells stimulated with AML cells expressing CD80 or IL-2 alone.
|

Similarly, AML patient PBMCs primed with autologous IL-2/CD80 AML cells had a higher frequency of IFN-gamma secreting cells and show cytotoxicity against autologous, unmodified blasts.
|

The effect of R1, R2 and R3 on the expression of the pro- and anti-inflammatory cytokines (TNF-alpha, IL-6, and IL-12) and the co-stimulatory molecules (CD40, CD80, CD86, and MHC class II) in MDDCs was examined.
|
2070 |
19853910
|
The exposure of R1 caused a dose-dependent increase in the expression of TNF-alpha, IL-12, CD86 and CD40, while R2 and R3 did not up-regulate these cytokines and co-stimulatory molecules.
|
2071 |
19853910
|
Furthermore, we found that R1 significantly increased the NF-kappaB expression in the nucleus (in a dose-dependent manner) and promoted the degradation of total IkappaBalpha levels, indicating that the NF-kappaB signaling pathway might involve in an R1-induced DC activation.

Administration of CTX increased the percentage of CD3, CD4, and CD8 cells with the increase in tumors being significantly greater than in spleens, and it also increased the percentage of B cells in spleens and tumors.
|
2087 |
19952956
|
Furthermore, CTX dramatically increased the frequency of tumor-infiltrating CD4 and CD8 cells containing interferon gamma, of cells expressing NK1.1, and of cells expressing the dendritic cell markers CD11c, CD80, and CD86, with the greatest increases seen among tumor-infiltrating lymphoid cells (TIL) from mice with small tumors.
|
2088 |
19952956
|
Although CTX decreased the percentage of TIL that expressed CD4 or CD8 together with CD25 and FoxP3 and were therefore considered to be regulatory T cells, it increased the frequency of TIL that stained for Gr1/CD11b, a marker for myeloid-derived suppressor cells.

|
Maturation of DCs with lipopolysaccharide (LPS; TLR4) concurrently with R848 (TLR7/8) induced a heterogeneous population of DCs that produced high levels of IL12 p70.
|
2169 |
21493800
|

2170 |
21493800
|
Priming with a homogenous subpopulation of LPS/R848-matured DCs that were CD83(Hi)/CD80+/CD86+ reduced this CD28+ subpopulation and induced T cells with an effector cytokine signature, whereas priming with the less mature subpopulations of DCs resulted in minimal T-cell expansion.

|
2235 |
21722668
|
It also promoted secretion of inflammatory cytokines IL-6, TNF-α, and IL-1β by human PBMC-derived dendritic cells.
|
2236 |

A Salmonella vector vaccine expressing the saliva-binding region (SBR) of the adhesin AgI/II of Streptococcus mutans has been shown to induce a mixed Th1/Th2 anti-SBR immune response in mice and to require Toll-like receptor 2 (TLR2), TLR4, and MyD88 signaling for the induction of mucosal anti-SBR antibody responses.
|
2238 |
21746857
|
Bone marrow-derived DC from wild-type and TLR2, TLR4, and MyD88 knockout mice were stimulated with Salmonella vector BRD509, the SBR-expressing Salmonella vector vaccine BRD509(pSBRT7), or SBR protein, and the DC responses to different stimuli were compared by assessing costimulatory molecule expression, cytokine production, and signaling pathways.
|
2239 |
21746857

|
2240 |
21746857
|
The low IL-12p40 and high IL-6 cytokine profile expressed by BRD509(pSBRT7)-stimulated DC may represent a shift toward a Th2 response, as suggested by the increased expression in Jagged-1.

Gag-VLPs efficiently activated human monocyte-derived dendritic cells (MDDCs), eliciting MDDC maturation with an associated increase in the surface expression of CD80, CD86 and MHC classes I and II, MDDC proliferation and proinflammatory cytokine production.
|
2243 |
21811551
|
Dendritic cells (DC) are professional antigen presenting cells and with respect to impact of PFCE particles on DC function, we observed that markers of maturation for these cells (CD80, CD86) were also significantly elevated following labeling with larger PFCE particles (560 nm).

We find that, compared with control groups, modification of DCs with HBV S-ecdCD40L fusion gene resulted in the activation of DCs with upregulated expression of immunologically important cell surface molecules (CD80, CD86 and HLA-DR) and proinflammatory cytokines (IL-12).
|
2248 |
21983157
|
The activation markers MHC-class-II, CD40, CD80 and CD86 on DCs were significantly upregulated by BCG-CS as compared to wild-type BCG (wt-BCG).

|
We found that Rv0315 functionally activated DCs by augmenting the expression of the co-stimulatory molecules CD80 and CD86 as well as MHC class I/II molecules.
|
2250 |
21993523
|
Moreover, it increased DC secretion of the pro-inflammatory cytokines IL-6, IL-1β, and TNF-α.
|
2251 |
21993523
|
In addition, Rv0315-treated DCs accelerated the proliferation of CD4(+) and CD8(+) splenic T cells from Mtb-infected mice, with increased levels of IFN-γ, in syngeneic and allogeneic mixed lymphocyte reactions, indicating that Rv0315 contributes to Th1 polarization of the immune response.
|

Interestingly, we show that upon activation by anti-CD40 and gamma interferon (IFN-γ), B cells from PKR(-/-) mice show diminished major histocompatibility complex class II (MHC II), CD80, and CD86 levels on the cell surface compared to wild-type (WT) mice.
|
2253 |
21994357
|
Our data also show that PKR is necessary for optimal expression of adhesion molecules, such as CD11a and ICAM-1, that are necessary for homotypic aggregation of B cells.
|
2254 |
21994357
|
Furthermore, in this report we demonstrate for the first time that upon CD40 ligation, PKR is rapidly phosphorylated and activated, indicating that PKR is an early and novel downstream mediator of CD40 signaling pathways.
|

|
2257 |
22116674
|
To decrease viral vector antigenic immunodominance and MHC class-I driven clearance, we engineered recombinant vaccinia viruses (rVV) expressing ICP47 alone (rVV-US12) or together with endoplasmic reticulum (ER)-targeted Melan-A/MART-1(27-35) model tumor epitope (rVV-MUS12).
|
2258 |
22116674
|
In this study, we show that antigen presenting cells (APC), infected with rVV-US12, display a decreased ability to present TAP dependent MHC class-I restricted viral antigens to CD8+ T-cells.
|
2259 |
22116674
|
While HLA class-I cell surface expression is strongly downregulated, other important immune related molecules such as CD80, CD44 and, most importantly, MHC class-II are unaffected.

DCs were evaluated for antigen uptake, and following maturation with LPS and IFN-gamma, DCs were assessed for expression of CD80, CD40, CD86, ICAM-1 and CCR7, production of IL-12p70 and IP-10, and induction of tumor-specific T-cell responses.
|
2261 |

Rv0577 recognizes Toll-like receptor 2 (TLR2) and functionally induces DC maturation by augmenting the expression of cell surface molecules (CD80, CD86, and MHC class I and II) and proinflammatory cytokine production (TNF-α, IL-1β, IL-6, and IL-12p70) in DCs on MyD88-dependent signaling, mitogen-activated protein kinases, and nuclear factor κB signaling pathways.
|
2269 |
22415304
|
In addition, Rv0577-treated DCs activated naive T cells, effectively polarized CD4(+) and CD8(+) T cells to secrete IFN-γ and IL-2, and induced T-cell proliferation, indicating that this protein possibly contributes to Th1-polarization of the immune response.
|
2270 |
22415304
|
More important, unlike LPS, Rv0577-treated DCs specifically induced the proliferation of memory CD4(+)/CD8(+)CD44(high)CD62L(low) T cells in the spleen of M. tuberculosis-infected mice in a TLR2-dependent manner.
|
2271 |
22536391
|
MVA-C infection of human monocyte derived dendritic cells (moDCs) induced the expression of HIV-1 antigens at high levels from 2 to 8 hpi and triggered moDCs maturation as revealed by enhanced expression of HLA-DR, CD86, CD40, HLA-A2, and CD80 molecules.

|
Antibody blocking of monocyte TLR4 inhibited surface expression, determined by flow cytometry, of the major histocompatibility complex class I, CCR7, CD80, CD83 and CD86 on TAPCells, reduced interleukin (IL)-6 and tumor necrosis factor -α gene expression evaluated by qRT-PCR, and also inhibited the TAPCells-mediated interferon-γ (IFN-γ) secretion of melanoma-specific CD8(+) T cells determined by ELISpot (p < 0.01).
|
2274 |
22552381
|
Moreover, CD8(+) T-cell activation capacity was significantly reduced in TAPCells bearing the TLR4 Asp299Gly receptor (p < 0.05).

We have previously reported that defined cocktails of cytokines, involving TNFα and IFNγ, induce mature type-1 polarized DCs (DC1s) which produce strongly elevated levels of IL-12 and CXCL10/IP10 upon CD40 ligation compared to "standard" PGE₂-matured DCs (sDCs; matured with IL-1β, IL-6, TNFα, and PGE₂) and show higher CTL-inducing activity.
|
2276 |
22561311
|
Restimulated lymphocytes, or their culture supernatants, enhanced the maturation status of immature (i)DCs, elevating their expression of CD80, CD83 and CCR7, and the ability to produce IL-12p70 and CXCL10 upon subsequent CD40 ligation.
|
2277 |
22729616
|
The results indicate that both JEV strains are capable of inducing various cytokines (type-I IFN, TNFα, IL6 and IL8) and co-stimulatory molecules (CD86 and CD80) in MDMs.

2278 |
22884511
|
Our results showed that Ag85A gene transfected DCs expressed high levels of key surface markers such as CD80, CD86 and MHC-II.
|
2279 |
22884511

2280 |
22927979
|
RB51-infected wild type BMDCs were mature and activated as shown by significantly up-regulated expression of CD40, CD80, CD86, MHC-I, and MHC-II.
|
2281 |
22927979
|
RB51-infected WT BMDCs also stimulated the proliferation of CD4(+) and CD8(+) T cells compared to uninfected WT BMDCs.
|
2282 |
22939910
|
The hybrid cell lines expressed HLA class I and class II molecules, and the major T-cell costimulatory molecules, CD80 and CD86.
|
2283 |
22939910
|
The enhanced T-cell stimulation was inhibited by CTLA4-Ig fusion protein, and by blocking antibodies to MHC class I and class II molecules.
|
2284 |
22977597
|
The results indicated that the B16F10 tumor cell vaccine treated with MIT alone or in combination with reserpine (RP) and verapamil (VP) for 12 h triggered apoptosis, and that the expression of CD80, the MHC II class molecule, NKG2D and its ligand were significantly increased compared to the expression levels in the control group.
|
2285 |
23042534
|
We previously demonstrated that the ovalbumin (OVA)-specific CD4(+) T cell-based (OVA-T(EXO)) vaccine generated using OVA-pulsed dendritic cell (DC(OVA))-released exosomes (EXO(OVA)) stimulate CTL responses via IL-2 and costimulatory CD80 signaling.
|
2286 |
23060228
|
BMDCs in vitro and DCs in vivo also display upregulation of activation markers CD80 and CD86 when treated with microparticles, again with no difference in conjugated antibodies, even the agonistic CD40 antibody.
|
2287 |
23246902
|
Phenotypic maturation of BMDCs was confirmed by conventional scanning electron microscopy (SEM), flow cytometry (FCM) and functional maturation by transmission electron microscopy (TEM), cytochemistry assay, Acid phosphatase (ACP) activity, FITC-dextran, bio-assay and enzyme linked immunosorbent assay (ELISA).We found that RGP up-regulated the expression of CD40, CD80, CD83, CD86 and MHC II molecules of BMDCs, down-regulated pinocytosis and phagocytosis activity, induced IL-12 and TNF-α production of BMDCs.
|
2288 |

23277917
|
Secretion of the cytokines interferon-γ, interleukin-1β, interleukin-2 and interleukin-10 in the CD4(+) T cell : DC co-culture (with or without chemokine pre-treatment) were essentially the same.
|
2290 |
23277917
|

TRIF is required for TLR4 mediated adjuvant effects on T cell clonal expansion.
|
2292 |
23457630
|
Activation of TLR4 by its ligands is mediated by engagement of the adapter proteins MyD88 (myeloid differentiation factor 88) and TRIF (Toll-interleukin 1 receptor domain-containing adapter inducing interferon-beta).
|
2293 |
23457630
|
Previously, we showed that TRIF, but not MyD88, plays an important role in allowing TLR4 agonists to adjuvant early T cell responses.
|
2294 |
23457630
|
In this study, we investigated the T cell priming events that are regulated specifically by the TRIF signaling branch of TLR4.
|
2295 |
23457630
|
We found that TRIF deficiency prevented the TLR4 agonist lipid A from enhancing T cell proliferation and survival in an adoptive transfer model of T cell priming.
|
2296 |
23457630
|
Importantly, TRIF alone caused CD86 and CD40 upregulation on splenic DC, but both TRIF and MyD88 were required for CD80 upregulation.
|
2297 |
23457630
|
The impairment of T cell adjuvant effects and defective DC maturation in TRIF (lps/lps) mice after TLR4 stimulation was mainly due to loss of type I IFN production, indicating that type I interferons are central to TLR4's adjuvant effects.
|
2298 |
23474022
|
The two molecules stimulated the proliferation of T-lymphocyte sub-sets (CD4/CD8) as well as the production of soluble mediators of Th1 (IL-2 and IFN-γ) and Th2 response (IL-4) in spleen cell culture supernatant.
|
2299 |
23474022
|
Furthermore, the two lipidated tripeptides enhanced the CD4, CD8, CD3 and CD19 cell populations as well as CD4/CD8 derived IL-2, IL-4, IFN-γ and TNF-α in whole blood of treated mice.
|
2300 |
23474022
|
Moreover, the two lipidated tripeptides enhanced the population of CD80 and CD86 in spleen-derived macrophages and did not show any hemolytic effect on rabbit RBCs.

23620105
|
DCs were transfected with IDO small interfering RNA and mRNA encoding human telomerase reverse transcriptase (hTERT) or survivin, two universal tumour antigens.
|
2302 |
23620105
|
Silencing of IDO in DCs did not affect the expression of the co-stimulatory molecules CD80 and CD86, but enhanced the expression of the CCR7 and CD40 molecules.
|
2303 |
23620105
|
The immunisation with this novel DC cancer vaccine was well tolerated and all patients developed delayed-type hypersensitivity skin reaction and specific T-cell response against hTERT and survivin tumour antigens.
|
2304 |
23633956
|
Finally, we were able to reduce immunodominance after i.d., but not i.p. infection, using a VACV expressing the costimulators CD80 (B7-1) and CD86 (B7-2), which is notable because VACV-based vaccines incorporating these molecules are in clinical trials.
|
2305 |
23658796
|
The DCs that received the particle-bound PADRE displayed all features of fully mature DCs, such as high expression of the co-stimulatory molecules CD80, CD86, CD83, the MHC-II molecule HLA-DR, secretion of high levels of the biologically active IL-12 (IL-12p70) and induction of vigorous proliferation of naïve CD4(+) T cells.
|
2306 |
23658796
|
Furthermore, the maturation of DCs induced by particle-bound PADRE was shown to involve sphingosine kinase, calcium signaling from internal sources and downstream signaling through the MAP kinase and the p72syk pathways, and finally activation of the transcription factor NF-κB.
|
2307 |
23704211
|
Tumor-associated CD11c(+) cells invaded by cps were converted to immunostimulatory phenotypes, which expressed increased levels of the T-cell receptor costimulatory molecules CD80 and CD86.
|
2308 |
23704211
|
Indeed, intraperitoneal cps treatment triggered rejection of established ID8-VegfA tumors, an aggressive xenograft model of ovarian carcinoma, also conferring a survival benefit in a related aggressive model (ID8-Defb29/Vegf-A).
|
2309 |
23735481
|
In vitro experiments using mouse bone marrow-derived DC (BMDC) demonstrated that PSK induces DC maturation as shown by dose-dependent increase in the expression of CD80, CD86, MHCII, and CD40.
|
2310 |
23764536
|
The immunopotentiating activity of OmpA is mediated by its ability to bind and stimulate macrophages and up-regulate the surface expression of MHCII, CD80 and CD40, leading to activation of CD4(+) T cells to secrete cytokines and express chemokine receptor and IL-12Rβ2, thereby orchestrating the bridge between innate and adaptive immune responses.
|
2311 |
23774693
|
We demonstrated that LD1ED III possesses an inherent immunostimulation ability that can activate RAW 264.7 macrophage cells by up-regulating their expression of CD40, CD80, CD83, CD86 and MHC II, whereas D1ED III could not induce the up-regulation of these molecules.
|
2312 |
23781340
|
In this study, IFN-gamma treatment of bone marrow-derived DC, followed by incubation with the TLR2, TLR4, or TLR9 agonists, enhanced DC activation compared to TLR ligation alone.
|
2313 |
23781340
|
Most notably, the upregulation of CD40 with LPS stimulation and CD86 with CpG stimulation was observed in in vitro cultures.
|
2314 |
23781340
|
Similarly, IFN-gamma coinjected with TLR ligands was able to promote DC activation in vivo, with DCs migrating from the site of immunization to the popliteal lymph nodes demonstrating increased expression of CD80 and CD86.
|
2315 |
23799649
|
Afterwards, the investigation into the maturation activation on primary bone marrow-derived DCs (BMDCs) showed that both Man-LPD and Man-free LPD induced remarkable up-regulation of CD80, CD86 and CD40 on BMDCs.
|
2316 |
23804272
|
We have discovered a method to induce stable tolerogenic ability to dendritic cells ex vivo using a mixture of phosphorothioate-modified antisense DNA targeting the primary transcripts of CD40, CD80 and CD86.

23825389
|
DCs treated with RpfB displayed features of mature and functional status, with elevated expression of cell surface molecules (CD80, CD86, and MHC class I and II) and proinflammatory cytokine production (TNF-α, IL-1β, IL-6, and IL-12p70).
|
2318 |
23825389
|
RpfB-treated DCs effectively polarized naïve CD4(+) and CD8(+) T cells to secrete IFN-γ and IL-2.
|
2319 |
23825389
|
Importantly, RpfB induced the expansion of memory CD4(+)/CD8(+)CD44(high)CD62L(low) T cells in the spleen of M. tuberculosis-infected mice.

2320 |
23876802
|
Gastric DC-LAMP-positive (DC-LAMP(+)) DCs express CD11c and high levels of HLA-DR but little CD80, CD83, and CD86.

23881522
|
Using mouse models, we previously demonstrated that ovalbumin (OVA)-specific dendritic cell (DC)-released exosome (EXOOVA)-targeted CD4(+) T cell-based (OVA-TEXO) vaccine stimulates efficient cytotoxic T lymphocyte (CTL) responses via exosomal peptide/major histocompatibility complex (pMHC)-I, exosomal CD80 and endogenous IL-2 signaling; and long-term CTL memory by means of via endogenous CD40L signaling.
|
2322 |
23881522
|
We prepared HER2/neu-specific Neu-TEXO and HER2-TEXO vaccines using adenoviral vector (AdVneu and AdVHER2)-transfected DC (DCneu and DCHER2)-released EXOs (EXOneu and EXOHER2), and assessed their stimulatory effects on HER2/neu-specific CTL responses and antitumor immunity.

TLR3 agonists improve the immunostimulatory potential of cetuximab against EGFR+ head and neck cancer cells.
|
2324 |
23894722
|
We investigated the effect of TLR3 agonists on cetuximab-mediated antibody-dependent cellular cytotoxicity (ADCC) against head and neck cancer (HNC) cells, as well as on dendritic cell (DC) maturation and cross-priming of epidermal growth factor receptor (EGFR)-specific CD8+ T cells.
|
2325 |
23894722
|
The DC-mediated cross priming of EGFR-specific CD8+ T cells was monitored upon in vitro stimulation with tetramer-based flow cytometry.
|
2326 |
23894722
|
The cytolytic activity of TLR3-stimulated NK cells differed among cells expressing different polymorphic variants of FcγRIIIa, and NK cells exposed to both poly-ICLC and cetuximab expressed higher levels of CD107a and granzyme B than their counterparts exposed to either stimulus alone.
|
2327 |
23894722
|
Poly-ICLC plus cetuximab also induced a robust upregulation of CD80, CD83 and CD86 on the surface of DCs, a process that was partially NK-cell dependent.
|
2328 |
23894722
|
Furthermore, DCs matured in these conditions exhibited improved cross-priming abilities, resulting in higher numbers of EGFR-specific CD8+ T cells.
|
2329 |
23935688
|
DsII-TN5 stimulated the expression of CD40, CD80, CD86, and IL-1 β in TCL-loaded DCs and downregulated the expression of TGF- β 1.

2330 |
23953841
|
Nanofibers were internalized by dendritic cells and macrophages at the injection site, and only dendritic cells that acquired the material increased their expression of the activation markers CD80 and CD86.
|
2331 |
23954198
|
Based on in vitro assay, 6-O-palmitoyl Agnuside (AG-3) was further taken up for detailed in vivo activity and found to significantly enhance the production of anti OVA IgG titer, neutralizing antibody (IgG1 and IgG2a) titer as well as soluble mediators of a Th1 (IL-2, IFN-γ)/Th2 response (IL-4) and proliferation of T lymphocyte subsets (CD4/CD8) and co stimulatory molecules CD80/CD86.

24041689
|
Co-stimulatory signaling pathway triggered by the binding of B7.1/B7.2 (CD80/86) of antigen-presenting cells (APCs) to CD28 of T cells is required for optimal T-cell activation.
|
2333 |
24041689
|
Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) is a negative regulator of T cell activation, which competes with CD28 for B7.1/B7.2 binding with a greater affinity.
|
2334 |
24041689
|
To develop a novel therapeutics specifically targeting CTLA-4, we constructed a DNA vaccine by cloning the sequence of CTLA-4 fused with a transmembrane domain sequence of placental alkaline phosphatase (PLAP) into a mammalian expression plasmid, pVAC-1.
|
2335 |
24095953
|
We have shown that IFN-α 1) up-regulates the expression of MHC II, CD40, CD83, CD80 and CD86 molecules on BMDCs; 2) down-regulates the rates of pinocytosis and phagocytosis by BMDCs as evidenced by the results of decreased ACP, and FITC-dextran bio-assay; 3) enhances the ability of BMDCs to drive T cell function; and 4) induces higher levels of IL-12 and TNF-α secreted by BMDCs.

The vaccine, human papillomavirus peptides with Candida, demonstrated partial maturation effects on Langerhans cells indicated by significantly up-regulated CD40 (p=0.00007) and CD80 (p<0.00001) levels, and showed T-cell proliferative capacity (p<0.00001) when presented by Langerhans cells in vitro.
|
2337 |
24135577
|
The cytokine profile (IL-1β, IL-6, IL-8, IL-10, IL-12p40, IL-23Ap19, IFN-γ and TNF-α) of Langerhans cells treated with the vaccine or Candida alone showed that IL-12p40 mRNA was most frequently induced, and IL-12p70 protein was detected in the supernatants.

24135577
|
The presence of pattern recognition receptors known to associate with Candida albicans (DC-SIGN, dectin-1, dectin-2, galectin-3, mincle, mannose receptor, Toll-like receptors-1, 2, 4, 6 and 9) were demonstrated in all subjects.

24146068
|
Exosomes were isolated and the typical exosomal protein markers, CD9, CD63, heat shock protein (Hsp) 70 and Hsp90, were found to be enriched in the exosomes derived from Rab27a‑overexpressing cells.
|
2341 |
24146068
|
Subsequently, these exosomes were demonstrated to be capable of upregulating major histocompatibility complex class II molecules as well as the co-stimulatory molecules CD80 and CD86 on dendritic cells (DCs), suggesting that more potent maturation of DCs was induced.
|
2342 |
24198843
|
The expression of the leukocyte surface markers such as phagocytic receptors CD11b, CD11c, CD14, and CD16/CD32 and the expression of the costimulatory molecules CD80, CD83, and CD86 were tested as well as the production of proinflammatory cytokines (IFN γ and IL-1 α) and growth factors (GM-CSF and FGFb) for cells of individual granulomas.
|
2343 |
24252697
|
In vitro, PS-F2 stimulated dendritic cells (DCs) to produce proinflammatory cytokines, including TNF-α, interleukin (IL)-6, and IL-12/IL-23 p40.
|
2344 |
24252697
|
PS-F2 also stimulated DCs to express the maturation markers CD40, CD80, CD86, and MHC class II.
|
2345 |
24252697

Furthermore, an in vitro mechanistic study showed that wolfberry supplementation enhanced maturation and activity of antigen-presenting dendritic cells (DCs) in aged mice, as indicated by phenotypic change in expression of DC activation markers major histocompatibility complex class II, cluster of differentiation (CD) 40, CD80, and CD86, and functional change in DC production of cytokines interleukin-12 and tumor necrosis factor-α as well as DC endocytosis.
|
2348 |
24336457
|
Also, adoptive transfer of wolfberry-treated bone marrow DCs (loaded with ovalbumin(323-339)-peptide) promoted antigen-specific T cell proliferation as well as interleukin-4 and interferon-γ production in CD4(+) T cells.
|
2349 |
24338222
|
In addition, we assessed the capacity of activated DCs to induce cytokine production and proliferation of lymphocytes.Listeria-derived protein fractions induced fully mature DCs expressing high costimulatory molecules such as CD80, CD86 and CD40.
|
2350 |
24343727
|
Using flow cytometry, we showed that rSjcPRMT1 slightly upregulated the expression of CD40, CD80, CD86, and MHC-II molecules of mouse bone marrow-derived dendritic cell (BMDC), indicating that rSjcPRMT1 could induce mouse BMDC to mature and, therefore, activate their immune response.
|
2351 |
24362470
|
Here, we found that colorectal cancer (CRC) cells treated with oxaliplatin (OXA) and/or 5-fluorouracil (5-Fu) released high levels of high-mobility group box 1 (HMGB1) and heat shock protein 70 (HSP70).
|
2352 |
24362470
|
After OXA/5-Fu therapy, the sera of CRC patients also exhibited increased levels of HMGB1 and HSP70, both of which are well-known DAMPs.
|
2353 |
24362470
|
The supernatants of dying CRC cells treated with OXA/5-Fu promoted mouse and human DC maturation, with upregulation of HLA-DR, CD80 and CD86 expression and enhancement of IL-1β, TNF-α, MIP-1α, MIP-1β, RANTES and IP-10 production.
|
2354 |
24362470

Interestingly, mDCs prestimulated with CCL21 showed higher levels of CXCL10 (IP-10) production, but not the production of CCL22, compared with untreated mDCs.
|
2359 |
24383579
|
IP-10 treatment during CTL generation with DCs dramatically enhanced tumour-specific CTL response compared with untreated CTLs, and these enhanced CTL-inducing functions of CCL21-treated DCs were inhibited by anti-IP-10 treatment.
|
2360 |
24385384
|
It was observed that PA-MSHA activated PMSM towards a classical activation phenotype via a toll-like receptor4/9-dependent mechanism, which increased interleukin-12 levels and promoted the expression of co-stimulatory and antigen-presenting molecules like CD80, CD86, and MHC-II (P < 0.05).
|
2361 |
24445619
|
There was significant upregulation of maturation markers (CD80, CD86, MHC-I, and MHC-II) in argon-helium freeze-thawed lysate-pulsed DCs.
|
2362 |
24445619

|
We have found that LDN enhances maturation of BMDCs as evidenced by 1) up-regulating the expression of MHC II, CD40, CD83, CD80 and CD86 molecules on BMDCs; 2) down-regulating the rates of pinocytosis and phagocytosis accompanied by the results of decreased ACP, and FITC-dextran bio-assay; 3) mounting potential of BMDCs to drive T cell; and 4) inducing secretion of higher levels of IL-12 and TNF-α.

Lin(-)MHCII(+)CD11c(+)CD205(+) mDCs (0.2% blood mononuclear cells) isolated from bovine blood were heterogeneous in cell size and CD205 expression.
|
2376 |
24502939
|
Using highspeed cell sorting, Lin(-)MHCII(+)CD11c(+)CD205(+) DCs were sorted into CD205(Hi) and CD205(Lo) subpopulations which were phenotypically distinct and differed significantly (P<0.01) in TLR gene expression.
|
2377 |
24502939

Relative to BCG-GFP, BCG-TB1860 effected a significant near total reduction both in secretion of cytokines IL-2, IL-12p40, IL-12p70, TNF-α, IL-6 and IL-10, and up regulation of co-stimulatory molecules MHC-II, CD40, CD54, CD80 and CD86 by infected bone marrow derived dendritic cells (BMDC), while leaving secreted levels of TGF-β unchanged.
|
2472 |
24945624
|
Splenocytes from mice infected with BCG-SSI showed significantly less proliferation and secretion of IL-2, IFN-γ and IL-17, but secreted higher levels of IL-10 in response to in vitro restimulation with BCG-TB1860 compared to BCG-GFP.
|
2473 |
24945624
|
Spleens from mice infected with BCG-TB1860 also harboured significantly fewer DC expressing MHC-II, IL-12, IL-2 and TNF-α compared to mice infected with BCG-GFP.

Priming of CD8 T cells by adenoviral vectors is critically dependent on B7 and dendritic cells but only partially dependent on CD28 ligation on CD8 T cells.
|
2475 |

|
Moreover, we found that CD80/86, but not CD28, was essential for efficient generation of both primary effectors and memory CD8 T cells.
|
2476 |
24951814
|
Interestingly, the lack of CD28 expression resulted in a delayed primary response, whereas memory CD8 T cells generated in CD28-deficient mice appeared almost normal in terms of both phenotype and effector cytokine profile, but they exhibited a significantly reduced proliferative capacity upon secondary challenge while retaining immediate in vivo effector capabilities: in vivo cytotoxicity and short-term in vivo protective capacity.
|
2477 |
24951814
|
Overall, our data point to an absolute requirement for professional APCs and the expression of the costimulatory molecules CD80/86 for efficient CD8 T cell priming by adenoviral vectors.
|
2478 |
24951814
|
Additionally, our results suggest the existence of an alternative receptor for CD80/86, which may substitute, in part, for CD28.

The rTs-Hsp70-activated DCs enabled the stimulation, proliferation and secretion of Th1/2 cytokines (i.e., INF-γ, IL-2, IL-4 and IL-6) in CD4(+) T cells from T. spiralis-infected mice.
|
2491 |
24962751

In the presence of 17β-estradiol, DCs from aged rats exhibited an impaired ability to mature upon stimulation with LPS, as shown by the lower surface density of MHC II and costimulatory CD80 and CD86 molecules. 17β-Estradiol alone enhanced CD40 expression in OX62+ DCs without affecting the expression of other costimulatory molecules, thereby confirming that the expression of this molecule is regulated independently from the regulation of other costimulatory molecules.
|
2537 |
25479725
|
However, although R848 upregulated the expression of MHC II and CD80 and CD40 costimulatory molecules on DCs, 17β-estradiol diminished the effect of this TLR agonist only on MHC II expression.

Through intersection analysis of the microarray results, we found that the Toll-like receptor signaling pathway was significantly activated, and NF-kB, TRAF3 and IRF7 were activated as early as 12 h, and MyD88 was activated at 48 h post-stimulation.
|
2544 |

2548 |
25775390
|
In addition, sRCPS enhanced the expression of CD40(+), CD80(+), CD86(+), MHC I and MHC II in dendritic cells (DCs) and upregulated the mRNA levels of MHC I, MHC II. sRCPS downregulated the frequency of CD4(+)CD25(+)Foxp3(+) Treg cells. sRCPS increased both cellular and humoral immune responses by upregulating DC maturation, and suppressing the frequency of Treg cells.

In vitro studies with human tumor cells indicated that CD80-Fc was more effective than antibodies to either PD-1 or PD-L1 in sustaining T cell production of IFNγ.
|
2553 |
25792524
|
Studies with human T cells blocked for CD28 and with T cells from CD28 knockout mice demonstrated that CD80-Fc simultaneously inhibited PD-L1/PD-1-mediated immune suppression and delivered costimulatory signals to activated T cells, thereby amplifying T cell activation.

|
Furthermore, CALR/MAGE-A3-infected DCs stimulated CD8(+) cytotoxic T lymphocytes, which in turn secreted higher levels of interferon-γ, which induced cytotoxic effects on ESCC cells expressing MAGE-A3.

Moreover, CVPS increased the expression of IL-2, IFN-γ, and IL-4 in CD4(+) T cells and IFN-γ expression in CD8(+) T cells.
|
2576 |
25934108
|
Additionally, CVPS enhanced CD40(+), CD80(+), and CD86(+) expression on DCs.
|

|
In contrast, CVPS downregulated TGF-β mRNA expression and the frequency of CD4(+)CD25(+)Foxp3(+) Treg cells.
|
2578 |
25934108
|
Taken together, these results indicate that administering CVPS as an adjuvant enhances both cellular and humoral immune responses via the TLR-2 and TLR-4 signalling pathways, thereby promoting DC maturation and suppressing TGF-β expression and Treg frequency.

Here, we describe the generation of a cell-based tumor vaccine via fourfold transient gene modification of a human renal cell carcinoma (RCC) cell line for high expression of CD80, CD154, GM-CSF, and IL-7 by use of MIDGE(®) vectors.
|
2583 |

|
The two co-stimulatory molecules CD80 and CD154 are expressed at the cell surface, whereas the two cytokines GM-CSF and IL-7 are secreted yielding cells with enhanced immunological properties.

Taking advantage of single-cell flow cytometry analyses, HlaH35L-specific B cells were characterized for the expression of CD38 and GL-7, markers of memory and GC, respectively, and for CD80 and CD73 activation markers.

|
We demonstrated that immunization with MF59-, but not aluminum salt-adjuvanted HlaH35L, induced expanded Ag-specific CD73(+)CD80(-) GC B cells in proximal- and distal-draining lymph nodes, and promoted the persistence of GC B cells, detected up to 4 mo after immunization.

We found that POL-P3b upregulated the expression of CD80, CD86, CD83, and major histocompatibility complex class II molecules on DCs, stimulated production of more interleukin (IL)-12, tumor necrosis factor-α, and less IL-10.

The pathophysiologic basis of these immune defects is hypothesized to be associated with a wide range of immunologic abnormalities, including an inability to sufficiently express the B7 family (B7-1, CD80; B7-2, CD86) of T-cell costimulatory molecules.
|
2594 |
26310460
|
However, testing the hypothesis that a state of chronic uremia contributes to attenuated expression of CD80 or CD86 has been difficult because few animal models faithfully recapitulate the immune defects observed in human CKD patients.

The PE25/PPE41 protein complex induced maturation of isolated mouse DCs in vitro, increasing expression of cell surface markers (CD80, CD86 and MHC-II), thereby promoting Th2 polarization via secretion of pro-inflammatory cytokines IL-4 and IL-10.
|
2598 |
26318856
|
In addition, PE25/PPE41 protein complex-activated DCs induced proliferation of mouse CD4(+) and CD8(+) T cells, and a strong humoral response in immunized mice.

We found that the costimulatory CD86 and CD80 molecules were significantly upregulated on rBCGhIL-18-infected DCs, whereas the stimulation of DCs with nonrecombinant BCG was less effective.
|
2600 |
26339658
|
The rBCGhIL-18 increased IL-23, IL-10, and IP-10 production by DCs to a greater extent than nonrecombinant BCG.
|
2601 |
26339658
|
In a coculture system of CD4(+) T cells and loaded DCs, rBCGhIL-18 favoured strong IFN-γ but also IL-10 production by naive T cells but not by memory T cells.
|
2602 |
26339658
|
Thus the expression of IL-18 by recombinant BCG increases IL-23, IP-10, and IL-10 expression by human DCs and enhances their ability to induce IFN-γ and IL-10 expression by naive T cells, without affecting the maturation phenotype of the DCs.

DNV stimulation of immature dendritic cells (iDCs) resulted in a significantly higher expression of DCs maturation markers (CD80, CD86 and HLA-DR) and induction of various cytokine and chemokine productions than in UVI-DENV-treated iDCs, suggesting a potential use of BCG- CS-NPs as adjuvant and delivery system for dengue vaccines.

PPE26 functionally stimulates macrophage activation by augmenting pro-inflammatory cytokine production (TNF-α, IL-6 and IL-12 p40) and the expression of cell surface markers (CD80, CD86, MHC class I and II).
|
2606 |
26439698
|
We observed that PPE26-treated macrophages effectively polarizes naïve CD4(+) T cells to up-regulate CXCR3 expression, and to secrete IFN-γ and IL-2, indicating PPE26 contributes to the Th1 polarization during the immune response.
|
2607 |
26439698
|
Moreover, PPE26 effectively induces the reciprocal expansion of effector/memory CD4(+)/CD8(+) CD44(high)CD62L(low) T cells in the spleens of mice immunized with this strain.
